AirBooster air amplifier systems are designed to boost plant air pressure at point-of-use workstations and pneumatically operated machinery when the available working pressure is insufficient. This energy-saving system allows for pinpointed increased air pressure without increasing the pressure on the entire plant air system. Easy to install and low-maintenance, the units are available in standard and custom configurations with 2:1, 5:1, 15:1 and 30:1 ratios. They can be used in explosion-proof applications, because they do not need electrical power, using the same compressed air source for both driving and amplifying.

Motor offers enhancements over earlier model

The compact CB1120 motor from Hägglunds is designed as a replacement for the Marathon MB1150 motor. Improvements over the Marathon motor include a strengthened connection block and a new casting to cope with the higher loads to which the motor is subjected. The number of components has been reduced, in line with the company’s commitment to modular motor construction. Besides the ad-

vantages of lower weight and smaller diameter, the CB1120 motor is more versatile, since it can be built with smaller steps in torque capacity (seven torque levels).

The motor will only be produced in splined output, but will also be available with a separate adapter for use in applications where a shaft coupling is required. The motor is suitable for mining, materials handling and pulp and paper industries.

Linear guide offers accuracy

NSK’s HA series of linear guides provides high motion accuracy, rigidity and load capacity. Featuring improved dust resistance, the guides are suitable for machining centres, high-precision lathes and grinding machines.

Ultralong ball slides minimize posture changes in the bearing that would normally result from ball passage vibration or rail waviness. To reduce the rail deflection that occurs when the rail is bolted to the base component, the series offers greater counterbore depth of the rail mounting hole. The series features a reduced body size that enables use in compact machinery. Despite the smaller size, the number of balls has been increased to improve rigidity, load capacity and friction.

Being prepared F

orget the lousy economy. You already have enough trouble keeping your machinery and equipment running effectively. Also, it’s often difficult to keep your team motivated and enthusiastic about its work. On top of that, it’s even a challenge to find the skilled workers you need in the first place.

And now this: What are you going to do if Canada faces a flu pandemic in the weeks ahead? Not only could the H1N1 flu virus decimate your maintenance, production and management staff, it could affect the regular flow of equipment and components from distributors and suppliers. It could affect

power and communications too.

And then again, it may all just be a lot of worry over nothing. Who’s to know?

But just in case, you should be prepared. That’s why we asked our Safety File columnist Simon Fridlyand to talk in this issue about preparing for a pandemic. Follow this advice (see page 24), and think carefully about the issues this article discusses, and you’ll be as ready as anyone in industry to deal with the consequences of a flu pandemic.

You can also forget the lousy economy because things finally seem to have bottomed out. Even in Ontario, manufacturing’s decline has stopped. Again,

with so many factors in the global economy affecting every aspect of industry here, from price-bouncing commodities to the plethora of made-in-China replacement products killing our export markets, who’s to know what’s really going to happen next?

Know this, though. Those who study and read and research say things really are starting to improve at Canada’s mines, mills, factories and other industrial facilities. It may be as slow as trying to turn around an ocean liner but it’s happening. And like everything else, you should also be prepared for it.

You may have been taking advantage of the economic slowdown by investing in staff training, catching up on all those non-urgent work orders, or finally getting all your equipment keyed into a CMMS system. If so, you’ll be ready to roll when the production lines speed up again, when dormant processes start pumping through product, and when

drill bits and saw blades need to be sharpened more frequently.

Continuing our role of helping you be prepared, this issue contains a variety of stories, from the cold, hard, frustrating facts of running the maintenance operations at a Quebec shingle plant, to tips on choosing the best work gloves for the job. Plus we present technical articles on gear drive replacement in variable speed drives, thermal imaging for predictive maintenance, and how to avoid air compressor failures.

There’s more, of course, as you’ll see by reviewing this issue’s Contents page.

So despite our diminished page count — a direct effect of that lousy economy — we’re still packing plenty of knowledge into every issue to help you in your work. And we’ve got lots more planned for future issues. As you might expect, we’re prepared!

Bearing market to reach $10.6 billion by 2013 Cleveland, OH — Ball, roller and plain bearing demand in the United States is projected to expand 3.0% per year through 2013 to $10.6 billion, according to a new study, Bearings, from The Freedonia Group Inc., a Cleveland-based industry research firm.

Sales increases for ball and roller bearings, including both mounted and unmounted types and associated parts, will outpace those of plain bearings, reaching $8.5 billion in 2013 (all figures are in US currency). Advances will be supported by sales of high-value, largediameter bearings as the wind energy and heavy equipment markets expand.

Continued, albeit moderating, growth

in the production of aerospace equipment and machinery will also support gains.

Recovery in motor vehicle production from the low levels of 2008, particularly in heavy truck and bus manufacturing, will also benefit bearing suppliers. Market gains will be dampened, however, as US companies in a variety of bearingusing industries continue to move manufacturing operations to offshore areas where labour costs are lower.

The strongest market gains through 2013 will be posted by roller bearings, benefitting from renewed strength in US production of motor vehicles and from sales of advanced, high-value products for applications such as wind

PT SALES UP IN THE US, DOWN IN CANADA Chicago, IL — US manufacturers experienced an increase in sales while Canadian manufacturers had a drop in sales in August 2009, according to the latest sales data released by the Power Transmission Distributors Association (PTDA). Confidence in the Canadian market (as measured on a scale of 1 to 10 with 10 being most optimistic) fell by 0.4 from the previous month to 4.1, the first drop since February 2009. US confidence is holding at a current negative position of 4.7 for the second consecutive month.

US manufacturers’ sales rose by 10.7% in August 2009 when compared to July 2009. Sales in August 2009 were down 30.6% compared to the same period last year. Orders in August 2009 increased by 10.4% over July 2009 orders.

Canadian manufacturers’ sales fell 6.6% compared to July 2009. Sales were down 23.8% when compared to the same period last year.

Product-by-product sales between July 2009 and August 2009 reflect the change in sales experienced by US and Canadian manufacturers. Six of nine product categories for US manufacturers — mounted bearings, positioning systems/linear motion products, shaft couplings, standard industrial motors, unmounted bearings and variable speed drives — posted sales gains.

For Canadian manufacturers, three product categories posted sales gains — shaft couplings, positioning systems/linear motion products and variable speed drives.

MANUFACTURING FINALLY SEES EMPLOYMENT UPTICK Ottawa, ON — Employment in Canada increased for the second consecutive month, up 31,000 in September 2009, driven by large full-time job gains, reports Statistics Canada in its latest Labour Force Survey. The unemployment rate fell by 0.3 percentage points to 8.4%, the first monthly decline since the beginning of the labour market downturn in the fall of 2008.

September’s full-time increase of 92,000, the largest since May 2006, was partially offset by part-time losses of

I N D U S T R Y November 2009

61,000. The increase in full-time work was mainly among youths and women aged 25 and over and in Ontario.

Despite September’s gains, full-time employment has fallen by 395,000 or 2.8% since the employment peak in October 2008.

Construction, manufacturing and educational services saw employment increases in September, while there were declines in transportation and warehousing.

British Columbia, New Brunswick and Prince Edward Island were the only provinces with notable employment gains in September. In Ontario, employment rose slightly as large full-time gains were dampened by losses in part time.

Since the peak in October 2008, employment has fallen by 2.1% (-357,000), with the bulk of the decline occurring between October 2008 and March 2009. Since then, the trend in employment has levelled, with the number employed almost the same in September as it was in March.

Canadians have been working more hours since April 2009. While the number of actual hours worked decreased 4.2% from October 2008 to April 2009, since then, there has been an increase in hours worked of 2.0%. In contrast, employment edged down 0.2% from April to September.

The increase in average hourly wages slowed to 2.5% compared with September 2008. This was the lowest year-overyear growth in two-and-a-half years.

Manufacturing employment increased by 26,000 in September, the first notable increase since February 2009. Employment in this industry had the sharpest rate of decline since the start of the labour market downturn in the fall of 2008, down 10.6% (-210,000).

By province, the most notable employment gain in September was in British Columbia, up 14,000. Although down 1.7% since October 2008, employment in this province has been increasing since March 2009 (+1.3% or +30,000). The unemployment rate, at 7.4%, declined by 0.4 percentage points in September.

In Ontario, a large full-time increase (+62,000) was dampened by a loss in part time (-49,000), leaving employment up only slightly in September. The unemployment rate declined by 0.2 percentage points to 9.2%.

September marks the third consecutive month of small employment increases in Ontario, totalling 39,000. Despite this increase, Ontario has suffered the fastest rate of employment losses since October (-2.9%), mostly in full-time and in manufacturing, construction and a number of service industries.

Employment also increased in New Brunswick in September, up 2,900, bringing the unemployment rate down 1.2 percentage points, to 8.1%.

Quebec’s employment level was little changed in September for the second consecutive month. The unemployment rate declined by 0.3 percentage points to 8.8%, as fewer people participated in the labour market. Since October, employment in this province has fallen by 1.6%, less than the national average of 2.1%.

The next release of the Labour Force Survey will be on November 6, 2009.

DEMAND FOR FILTERS TO RISE 3.3% ANNUALLY Cleveland, OH — Demand for filters in the United States is expected to increase 3.3% per year to US$12.4 billion in 2013.

Advances will be spurred by pending changes in environmental regulations, particularly those involving reduced emissions from power plants and diesel engines, and improved operational efficiency of motor vehicle engines.

Demand will also be boosted by manufacturers’ increasing interest in reducing costs by reclaiming production inputs from process water and recycling process water for reuse.

Gains will be driven by ongoing sales in the aftermarket, which accounts for the vast majority of demand.

These and other trends are presented in Filters, a new study from The Freedonia Group, Inc., a Cleveland-based industry research firm.

In 2008, internal combustion engine filters (oil, air intake, fuel, cabin air and other filters) accounted for the largest share of filter shipments with 39%. Although this is a relatively mature product group, sales will benefit from the ongoing development of new types of emissions filters, particularly for diesel engines, and the growing aftermarket for cabin air filters.

Shipments of fluid filters (e.g., fluid power, municipal water and waste, consumer water and industrial fluid filters) accounted for the second largest share of total shipments, with 35%. Although they compete with membrane separation technologies, fluid filters will also benefit from their use as pretreatment steps for these technologies.

Shipments of air filters are expected to post the strongest growth through 2013, driven by changes in environmental regulations and advances in the consumer market.

Filters (published 08/2009, 333 pages) is available for US$4,800 from The Freedonia Group Inc., www.freedoniagroup.com.

MRO Editor’s note: More detailed versions of many of these stories, along with additional news items, can be found online at www.mromagazine.com.

When you think “Quality”, you think about bearings that can withstand high speed, shock loads, misalignment and marginal lubrication conditions. We think about maximizing uptime and lowering maintenance costs with quality components supported by 24-hour service and worldwide distribution.

• Pumpmaker KSB, Mississauga, ON, has marked the 50th anniversary of its relationship with Vancouver-based engineering firm Inproheat Industries

Ltd. by awarding it the Partnership of Excellence, its highest recognition of a partner’s contribution to KSB’s success.

“What started half a century ago with the sale of KSB’s first boiler feed pump in North America through Inproheat is still a lively and extremely vibrant business connection,” says Jens-Uwe Strunk, president and CEO of KSB’s Canadian subsidiary. It was Inproheat — and its still-energetic founder and owner, Eric Panz, 81 — that helped to put KSB on the map in North America. Long before the pump manufacturer launched its own subsidiaries in the US in 1963 and Canada in 1990, the Austrian-born engineer introduced KSB’s boiler feed pumps to the North American market.

KSB recognizes its 50-year relationship with Inproheat.

• In other news, KSB has received an order for boiler feed and reactor coolant pumps worth around €50 million. The

Mr.0 The Practical Problem Solver

Getting technicians to read work orders

Call your sales office now to get more information!

Reader Service Card No. 120

Problem: One of the most difficult habits to form when trying to establish planned work methods is getting people to actually read work orders. In the past, work orders may not have contained much useful information, so nobody read them. But once your work orders have a full work plan attached, with instructions, drawings, parts lists, safety considerations and permits, how can you effectively change how maintenance technicians use them? If no one reads these work packages, they have no value.

Solution: Here’s a fun trick to help build a new habit for reading work orders. Find a simple reward, like movie tickets or gift certificates to a local store. Have your maintenance planners add some text to a few work orders every week like this: “The first person who sees this message, and calls me, gets two free tickets to the movies.” Bob, The Planner.

For just a few dollars weekly, you can drive some change, and make it fun to read work orders. Try placing the messages in different places in the materials to encourage thorough viewing. Don’t make it too easy. Once this system gets rolling, you’ll see a great response to it. Give it a try!

Bringing Maintenance

BY CARROLL MCCORMICK

Tapping knowledge on the shop floor helped fixed a broken PM system for BP Canada.

Photos by Carroll McCormick

Above: The grit and grime of an exceptionally harsh production environment made a farce out of the old PM program. Right: It took a mechanic to suggest belts that last months longer. Bottom: Maintenance manager Henri Boucher loves machinery, and his thoughtful strategies transformed the plant’s PM program into something usable.

A

fter more than a decade of trying to implement a preventive maintenance program, Building Products of Canada Corporation, a huge roofing shingle manufacturer in Lasalle, QC, was still light years away from success.

“For me, I was at a 25% confidence level on the effectiveness of the PM,” says Denis Lanciault, vice-president of operations at the company, which goes back over 100 years. “The costs were really high, we were changing things we did not need to change, but output was still the same because other things were breaking.”

A year and a half after pulling Henri Boucher, the paper mill foreman, back from the brink of retirement to do brain surgery on the critically-ill PM patient, Lanciault’s confidence in the PM program has soared. “Our downtime has been cut by half. I think Henri will be able to deliver everything in three years,” Lanciault says.

The secret to unballing the mess and returning maintenance to good health

has had nothing to do with complex, impenetrable methods. Rather, say Lanciault and Boucher in unison, as though reciting an oft-practiced pitch, “It is back to basics.”

The Lasalle plant, only a few kilometres from downtown Montreal, has two production lines: RF1 and RF2. In places two storeys high, these giant “machines,” as everyone refers to them, churn out a very healthy percentage of the 45 million bundles of shingles the Canadian marketplace consumes each year.

The preventive maintenance (PM) program Boucher inherited had mechanics swarming like flies all over each other on the machines and saw none of them responsible for anything. The checklists — created by maintenance consultants — were so huge that during shutdowns the men spent more time playing PM catch-up than dealing with current problems or repairs.

The mechanics quickly learned that many items on the list were pointless.

They gradually became contemptuous of the white-shirted PM creations and fell back onto breakdown maintenance

A Thoughtful Mechanic A lifelong gearhead with a grip like a bench vice, Henri Boucher ran a tight ship for 15 years as foreman in BP Canada’s paper mill until it closed in 2006. After consulting on the overhaul of the mutant PM program in the shingle plant for a few months, he took over full-time as maintenance manager in August, 2008.

He likes his work and has a smile or a joke for everyone he meets as he roams the production floor. He likes to see engineers with dirty hands and grubby clothes.

He points to a young P. Eng. buck working with a mechanic on some spray gear, and he says: “My dream is to have mechanics and engineers working together.”

strategies. “The consultants copied what they knew from outside. But they never understood how we ran our machines,” Lanciault says.

Boucher, starting with RF1, divided it into 14 sectors and assigned one mechanic to be responsible for each sector and do a daily inspection. Boucher created efficient routes with no wasted steps. At first the routes took up to five hours to do, but with practice that dropped to a couple of hours.

“Every day all our machines are

looked at by our guys — look, feel, take temperatures. I want to know everything that is going on with our machines,” Boucher explains.

Now the mechanics draw up the repair orders and decide when shutdowns are necessary. Compare this to the learned helplessness created by the old PM. “We were all controlled by the system. The guys were waiting for it to tell them what to look at, rather than doing what they should do,” Lanciault explains.

The old system not only frequently told them to look in the wrong places, its creators never incorporated the maintenance team’s knowledge. “The guys on the floor were saying, ‘you are spending a lot of money on consultants. You are not asking us’,” Lanciault adds.

The consultants had ignored the realities of the production environment, where equipment lives and dies by the conditions in which it operates. Boucher points to a shaft and bearing, half-covered with some kind of corruption, where the machine applies sand to hotcontinued on page 14

tarred felt. “This bearing might last 25 years, but here — maybe three months. The PM was not based on reality. We have sand, asphalt, gravel, limestone, hot and cold water, tar … these are really hard on machines. A contaminated bearing might last only three weeks.”

Since the mechanics now have responsibility and control, they can apply their knowledge to making the PM fit the machines as they are actually being used. As each became familiar with his sector, he began noticing that certain checks might not have to be made so often, and the PM routine was modified.

Boucher was also prepared to listen to their ideas.

“Most of the suggestions come from the mechanics,” he says. One mechanic, for example, pointed out that belts on a die cutter were being replaced every few weeks, year after year. He suggested a different kind of belt, which has lasted six months and counting.

“The guys were given empowerment. They liked that,” Lanciault says. “The guys were also responsible for failures. Henri would ask them questions about that, say if a part was installed improperly and broke. How do you expect guys to take care of the machines if you don’t empower them? If they have a lack of knowledge, you train them.”

Speaking of lack of knowledge, Lanciault, who sounds more like Boucher’s agent than his boss, tells a curious story: “The big difference between Henri and his predecessors is that Henri does not pretend to know what he does not. He questioned the way that the engineers installed things. He read, and installed things the way the manufacturers asked for.

Some of the previous managers did not do this.”

The palletizer, which does the work of strong men stacking heavy packages of shingles, was causing major migraines. “We lost time like you wouldn’t believe,” Lanciault recalls. “Henri, because he didn’t know about the palletizer, read the book on it. He discovered that an exhaust valve was not properly set up. He fixed it and the problem went away.”

The limestone filter screen was also causing grief.

Boucher did not know it from bananas, but it was not a problem: He read the book and discovered that there were eight ways to install it, and someone had

figured out a ninth, wrong way. Boucher made the change and that problem vanished. There have been many cases like these, according to Lanciault.

Boucher keeps track of the 1,200 pieces of equipment and his maintenance scheme in a computerized maintenance management software (CMMS) program, the Ross ERP Maintenance Management module. Between the CMMS and paper records, the maintenance team is beginning to build up a history.

“There was a little bit of maintenance history, but when I took over, I made it more rigorous, like having all of the details — for example, parts, cost, time — on the work order. Now I can look a year back and see the people, parts, etc., for a repair,” Boucher says.

As for comparing the performance of the equipment under his watch with before he took over, Boucher cannot see the value: “I don’t want to compare now with before I started on this project.” What both Boucher and Lanciault do know is that mechanical downtime on RF1 has steadily dropped.

The secret to the success of the turn-around of the plant’s PM, according to Lanciault and Boucher, is to take it away from the white-collar office crowd and give it back to the people who run the equipment, who know how it is used and who are the most capable of judging what makes sense and what has to be changed.

Lanciault says, “When you go to an outside firm, [you are saying that] they have knowledge and that you don’t. This is an abdication of responsibility. The job to make PM work has to be done on the floor.”

Making hand safety your policy

November 2009

It is important to remember that it takes only seconds for a life-changing event to occur.

BY GIL LEVERNE

Chemical-resistant gloves are available to protect the hands of anyone who comes in contact with harsh substances.

G

lobally, worker safety is becoming a critically ranked priority in industry. With more than 250,000 serious injuries to fingers, hands and wrists each year in North America alone, hand safety is a leading concern.

Because lack of attention and human error are responsible for most hand, finger, wrist and lower arm injuries, it becomes imperative for employers to create a high level of hand safety awareness among workers.

Worker’s compensation claims are directly tied to how a company manages its safety programs. If a worker is injured because the employer did not provide the correct personal protective equipment

(PPE), then the claim can be much higher against the employer.

It is important to remember that it takes only seconds for a life-changing event to occur. In addition, without clear direction, workers often carelessly place their non-dominant hand in harm’s way while performing tasks with their dominant hand.

A strong hand-protection program begins with providing proper-fitting protective gloves designed for a specific task.

Because no single glove provides protection from all types of hand injuries, selection is based on performance characteristics of the gloves in relation to the task being performed.

In metal construction, these might be

cut-resistant gloves, while gloves that absorb oil for sure grip are key in environments where workers handle slippery components. Chemical-resistant gloves are available to protect the hands of anyone who comes in contact with harsh substances. In fact, the varying chemicalresistance requirements of different tasks have led to the development of a website, www.chemrest.com, that is devoted to helping companies select the right glove for the right job.

Providing the right hand protection is one thing. Establishing a safety program that achieves a high level of awareness and makes wearing PPE second nature for workers is quite another. The answer lies in creating a safety culture that penetrates every level of an organization, from the executive suite to the manufacturing floor, the maintenance department and the mailroom.

Fortunately for companies addressing hand safety for the first time, there are many templates available for safety programs that can be customized to meet an individual organization’s situation and criteria. There also are companies that will come to your facility and develop a program for you. Most importantly, whether you develop the program in-house or outsource the work, successful program development requires that every worker position be evaluated in terms of risks, safety protocols and the PPE required.

This is hard work that cannot be done from an ivory tower. It requires involving workers, their team leaders, their superintendents and anyone else who can provide valuable input. Worker surveys and interviews can be used to dig deep into safety requirements and best practices.

Safety protocols can then be documented and PPE prescribed department-by-department, position-by-position.

Once the program is down on paper,

the hard work begins. This is essentially an internal marketing assignment to sell the entire company workforce on hand safety. This involves all of the following: • Creating worker information sheets that make hand-protection protocols understandable • Establishing a safety board that includes members from all stakeholder groups in the organization, from the factory floor to the executive suite • Training workers on hand protection, including glove selection, glove storage and techniques for testing previously worn hand protection to be certain it is still effective • Making it easy for workers to obtain the proper hand protection for their specific tasks through convenient glove stocking and intuitive labelling.

Use every internal communication vehicle available to you to promote hand protection, including: • Displaying posters and worksite banners • Using employee newsletters to communicate safety alerts that talk about new protocols and discuss near misses and minor accidents and what is being done about them • Posting break-room announcements • Using paycheque stuffers • Discussing hand protection at worker meetings.

These are just a few of the many ways to keep hand safety in high profile. Promotions of the type described here are a good way to keep safety on the minds of workers. They will help ensure that your hand safety program will jump off the paper and stick in the workplace. MRO Gil LeVerne is the manager, marketing communications, for Best Glove Inc., Coaticook QC.

Cutting out cuts Electrician relies on work gloves that provide both dexterity and cut protection.

B

arbara Monk of Odessa, ON, says there have been few times during her 21-year career that her hands have not been covered with cuts and nicks. As a journey-level electrician and member of the International Brotherhood of Electrical Workers, Monk typically works on new construction and retrofit projects.

As part of her job, Monk strips insulation from electrical wires and cables to make electrical connections and uses a hacksaw to cut cable and conduit. She frequently handles fixtures and cable trays that have sharp edges.

In the past, the electrical contractors for whom Monk worked provided her and other electricians with leather-cotton gloves that often deteriorated quickly and did not provide the cut protection required.

Sometimes the gloves were so large that they fell off, leaving her hands exposed.

In recent years, some contractors supplied ‘pimple grip’ cotton gloves, which fit better and offered greater cut resistance, but did not provide the dexterity and tactile sensitivity needed for finite handling of small objects.

More recently, Monk began using different gloves while working at the con-

struction site for a refinery in Sarnia, ON. The HyFlex 11-500 gloves she received include a foam nitrile coating to protect workers handling sharp-edged materials and tools, and have a DuPont Kevlar liner.

“We were doing a retrofit so the plant could produce ethanol,” Monk said. “The safety rules at the site required everyone to wear gloves at all times, and the contractor provided the HyFlex gloves.

Because the product was available in different sizes, I had no problem finding a size to suit me. The HyFlex gloves fit me like a second skin, which is important, since I am wearing them nine to 11 hours a day.”

After the Sarnia project, Monk said she continued to wear the HyFlex gloves while she was working on three other jobs, laundering them as needed. The contractor at an ethanol plant construction site in Johnstown, ON, where she presently works, also provides HyFlex 11-500 gloves to every

electrician using a knife for any task.

Monk said since she began wearing these gloves, she has not suffered from the nicks and cuts that required a quantity of bandages in the past.

“When I wear the HyFlex gloves, my hands feel safe from cuts for the first time,” Monk said. “The gloves are comfortable and because they fit so well. I

have the dexterity I need to perform the majority of jobs. I remove the gloves only for the most finite tasks.”

She added that she often recommends the gloves to other electricians who are not familiar with the product.

Protecting hands from chemicals BP’s staff uses very strong acids and corrosive chemicals so it dare not get its health and safety and PPE approach wrong.

W

ith 750 staff working at the large BP plc chemical manufacturing plant in Hull, UK, producing over one million tonnes of chemical products per year, site health and safety manager Andy Bell faces a constant challenge to ensure the wellbeing of workers.

Working with a range of hazardous materials, including acetic acid, ethyl acetate and vinyl acetate, which are used in a wide range of chemical-based products, including adhesives and paints, health and safety is the number one priority.

With the hands of staff throughout the plant in the direct firing line for potential injury, BP works with hand protection experts from Marigold Industrial to provide the right gloves for

members of its plant and lab staff.

“A large proportion of the staff is working constantly with very strong acids and corrosive chemicals so we really cannot afford to get the health and safety and PPE approach wrong. “In addition to manufacturing chemicals, we also have a large lab where staff is constantly looking at developing new formulations or creating new ways to manufacture our chemicals,” says Bell.

“Whilst we ensure working practices

on site reduce the need for direct contact between staff and chemicals to an absolute minimum, we cannot engineer this out completely.

“As a result, we have to ensure that where PPE is required, it is extremely high performance and provides the level of protection that we require,” says Bell.

With a wide range of hand hazards on site, two particular personal protective equipment (PPE) solutions are provided in the shape of Marigold Industrial’s G25B and GO4Y gloves. The G04Y is used almost exclusively by staff working in the BP laboratory, while the G25B is used across the site. The blue nitrile G25B is resistant to a wide range of solvents and oil-based chemicals. It has a flock lining for comfort

and a raised palm pattern for enhanced grip. The GO4Y is ideal for use in chemical, electronic and preproduction areas.

“The Marigold Industrial gloves perform extremely well from a protective perspective but they also provide a good fit, which is very important when staff have to wear them throughout their shift,” adds Bell. “They also come in a wide range of sizes, which again is important when you have a lot of staff working on site, as we do.

“We place great faith in our PPE suppliers — whether it is for chemical suits, breathing apparatus or gloves. Their products are an essential ingredient in our health and safety approach, so we are extremely careful to select the best products for the many varied jobs being carried out on site.

Selecting the best glove materials According to Marigold Industrial, the key drivers of industrial glove design are to achieve optimal comfort, dexterity and grip. Gloves can be made from natural rubber latex, synthetic rubber latex or textiles. The characteristics of each vary and the level of protection offered has to be considered glove by glove, chemical by chemical, for individual applications.

Using natural rubber latex to manufacture gloves provides a number of advantages, including high tensile strength, superior tear resistance, and good acid and alkali resistance.

However, natural rubber gloves do not hold up well in organic solvents, oils, greases or fuels such as kerosene or gasoline. Also, natural rubber latex has been shown to cause allergic reactions in sensitized individuals.

Natural rubber latex is produced from the sap of the rubber tree Hevea brasiliensis, which is mainly harvested in Malaysia and Thailand.

This latex is widely used in glove manufacturing and provides highly effective protection against chemicals as well as offering comfort, flexibility and dexterity.

Using synthetic rubber latex to manufacture gloves provides a number of advantages, including enhanced physical properties against abrasion and good chemical resistance to oil-based compounds such as grease, petrol and diesel.

Chemical-resistant glove materials other than natural rubber include butyl rubber, neoprene, nitrile, polyurethane and PVC — sometimes in combination and in differing thickness and styles.

Using textiles to manufacture gloves provides a number of advantages, including enhanced performance against cuts and thermal protection against the extremes of both heat and cold.

Today’s range of textile gloves uses many specialist types of yarn that are sourced from various suppliers.

How to get the best, easiestto-install replacement drive for your application.

Images courtesy SKF Group

Proper planning simplifies gear drive replacement Completed drop-in drive package was designed to replace an obsolete drive without requiring changes to the existing equipment.

BY RICK LYNCH AND NICK DERUS

S

ooner or later, all gear drives will wear out. Whether it’s 60 years or six years after they were installed, the time will come when they have to be replaced. Proper planning and a well thought out replacement strategy can ensure continued smooth operation.

When a gear drive needs to be replaced, it can be frustrating when an exact replacement isn’t readily available.

Because the number of US-based gear drive manufacturers has dwindled over the past 20 years, there may be no direct replacement or spare parts inventory available for much of their installed base.

With ever more frequent design changes, some drives only a few years old have become obsolete. This can leave a user no choice but to search used equipment lists or buy a new and different drive. When the substitute equipment arrives, it may not fit properly or be as suited for the intended use as the original drive.

When replacing a gear drive, there are several important questions to ask and factors to consider.

1. How does the replacement fit the envelope of the existing drive?

The most obvious concern is the base-tocentreline distance. If the old drive measured 10 in. from the base to the shaft centerline, and the replacement measures 11 in., this is obviously a big problem, especially if the drive is mounted on a concrete foundation.

If the drive being replaced is very old, it may not be an issue, since drives have gotten smaller over each generation, but it can be a deal breaker if the drive being replaced is of a newer generation.

Other important dimensional con-

cerns include space considerations and interference with connected equipment or structures. Also consider what must be done with the motor to accommodate the new drive.

2. How does the replacement fit the connected/connecting equipment? Changes in solid-shaft diameters will affect couplings, sheaves, sprockets and other mounted equipment. Changes in bores of hollow-shaftmounted drives may make installation difficult or impossible.

In some cases these changes can be accommodated by changing bushings or re-boring. In others, a new hub, bushing or sprocket may be required. If such modifications become too expensive, it may be preferable to replace the drive with one having a special shaft to suit the application, if it is available.

3. Are there any foreseeable mechanical issues? Any time a drive is replaced, application parameters should be confirmed. Older drives were designed conservatively, so users could increase power over time without causing any problems. In some cases, motor horsepower and loads were increased by 50% to 100%. However, newer drives are developed with less conservative design practices and will not last long if misapplied or overloaded.

Ratios are another major concern, since it is unlikely a new drive will have exactly the same gear ratio as the drive it replaces. In most applications, ‘close’ is good enough, but in some cases, a change in ratio will be detrimental. These may include certain pump applications, dual drives and metering conveyors, among others. In these cases, it may be necessary to request a special ratio that is the

same or near that of the old drive.

Relative shaft rotations also may be an issue. If the old drive is a double-reduction gearbox and the replacement is a triple-reduction gearbox, the extra reduction and change in rotation can cause insurmountable problems.

This is more of a concern where the driver is an engine with a fixed direction of rotation. On electric motors, the leads can be switched to change the direction of motor shaft rotation. Relative rotation can also be an issue if there is some element in the drive train that must rotate in a specific direction, such as some variable-fill fluid couplings and clutches.

site visit to see the application.

Ask for a written quotation of what is being proposed, and insist that it include full information on what will be required in the interchange. Will it require moving the motor, ordering a new coupling, sheave or sprocket, re-drilling the foundation or other changes?

Finally, make every attempt to simplify the change-out. Ask the bidder to provide a drop-in with an adapter base or bedplate to suit the existing foundation, new coupling, hub, etc. What could be easier than taking the new drive off the truck and bolting it in place of the original drive?

How to choose a replacement drive With all these considerations, how can you get the best, easiest-to-install replacement drive? Here are some suggestions: First, work with a supplier that you know has the experience and attention to detail to handle the undertaking.

This is not a job to shop around to the lowest bidder.

Work with a gear drive manufacturer that has a good library of competitive drive information. Knowing critical dimensional and rating information of the drive to be replaced is extremely important, and the manufacturer’s competitive knowledge can help offset the lack of detailed user records.

Next, make sure the bidder is given all the information regarding the application. Original paperwork and drawings are certainly a plus, but if they are not available, get full information from the existing drive nameplate, then verify that it reflects the current operation. Make sure the bidder includes a

An example from the field When a world-class producer of industrial chemicals needed to replace the gear drive on an agitator vessel at one of its North American plants, a replacement wasn’t available from the original manufacturer. A custom gearbox built to fit the application would have required a 25week lead time. Instead, the company’s contract engineering firm worked with Rexnord Industries, LLC, which made a transition base that allowed a drop-in replacement with a standard Falk gear drive in less than four weeks.

Because the company was rebuilding the equipment, time was less of an issue than in a breakdown situation. However, the long lead time and considerably higher cost of a custom gearbox made the alternative of a standard gearbox with a custom base a better choice.

The solution included a Falk M1150DBC3 reducer with a 64.67:1 ratio, a transition base, AirMax breather kit, sealed dipstick to exclude moisture, Wrapflex 20R10 high-speed coupling, Steelflex 1130T10 low-speed coupling, and a coupling guard.

The project manager said the company has similar equipment at other plants, some of which has been running for 45 years. He noted that the combination of the standard gear drive and adapter base provides a standard design that will make it easier to replace these drives when necessary. In fact, the company already has ordered two more of the drive packages for similar equipment at one of its plants in France.

Identifying equipment problems before failure

Predictive maintenance (PdM) programs monitor equipment condition, with the goal of identifying problems in advance and avoiding equipment failure. One powerful tool for monitoring rotating equipment such as motors and gearboxes is thermal imaging.

Left: Colour infrared images clearly highlight overheating. Centre: Overheating can be caused by a variety of problems, from inadequate airflow to insulation failure. Right: Thermal images make pretty pictures, but the story they reveal is anything but pretty.

T

hermal imagers capture heatbased images, using colour to correlate every pixel of an electronic image to a specific surface temperature. For motors and gearboxes in mechanical drives, overheating often signals impending breakdown. A thermal image makes it immediately clear what part of the motor is overheating, and to what extent.

Standard practice follows three basic methods: 1. Regularly compare the operating temperatures of like equipment, performing similar functions. 2. Regularly compare the operating temperature of a single unit to manufacturer’s standards. 3. Regularly compare the operating temperature of a single unit to previous images of the same unit.

More specific inspection guidelines follow.

Motors Ideally, you should check a motor while it is running at a minimum of 40% of its typical load. That way, measurements can be properly evaluated and compared to normal operating conditions.

By capturing an image of a whole motor, you can determine the operating temperatures of bearings as well as the temperature and temperature variations of the unit’s entire surface.

All motors have a normal thermal

pattern. Training and experience with both motors and thermal imagery make a thermographer familiar with motor heat patterns and how they relate to their operation. An experienced thermographer can use thermal imaging to identify conditions such as inadequate airflow, unbalanced voltage, impending bearing failure, and insulation degradation in a motor’s rotor or stator.

An experienced thermographer can also identify a misalignment in a shaft coupling associated with the motor.

And even a novice can spot anomalies in a motor compared to other similar motors under similar loads and then flag that deviant motor for further investigation.

Troubleshooting motors If overheating appears to be due to one of the following situations, consider the action described.

• Inadequate airflow. If a brief shutdown is possible without affecting vital processes, shut off the motor long enough to perform minor cleaning on the air intake grills. Under any circumstances, schedule a thorough motor cleaning during the next planned facility shutdown.

• Unbalanced voltage or an overload.

The usual cause — a high-resistance connection in the switchgear, disconnect, or motor connection box — can usually be pinpointed by an infrared

inspection and confirmed using a multimeter, clamp meter or a power quality analyzer.

• Impending bearing failure. When the thermal images indicate an overheating bearing, generate a maintenance order to either replace or lubricate the bearing. Vibration analysis will help you determine the best course of action.

• Insulation failure. If it will not too greatly affect production, de-rate the motor in accordance with NEMA standards. Under any circumstances, generate a work order to replace the motor as soon as possible.

• Shaft misalignment. In most cases, vibration analysis will confirm a misaligned coupling. If a shutdown is possible, dial indicators or laser alignment devices can be used and the misalignment can be corrected then and there.

Gearboxes The lifeblood of any gearbox is the oil in it that lubricates the gears. If the oil level in a gearbox gets too low or loses its ability to lubricate, the gearbox will eventually fail, preceded by overheating.

Traditionally, preventive maintenance for gearboxes has consisted of regularly checking their oil levels and replenishing lost oil. Some maintenance departments add a predictive element to gearbox maintenance in the form of oil sampling and analysis. Oil analysis, usually performed by an outside labora-

tory, reveals if the oil in a gearbox has lost its ability to lubricate and will detect any metal particles in the oil, a telltale sign of gear wear that foreshadows a possible failure.

These gearbox maintenance measures are time-consuming and expensive and require shutting down the equipment. Also, gearboxes often are inaccessible or in unsafe locations, making oil-level checking and oil sampling difficult. Fortunately, thermal imaging is an alternative PdM approach.

Since gearboxes generally overheat before they fail, an infrared (IR) camera can detect when a gearbox is running hotter than normal and/or hotter than similar gearboxes performing similar work in similar environments.

Because thermography is a non-contact, non-destructive technology, even inaccessible gearboxes in dangerous locations can be scanned while they are running. These devices can capture thermal images as well as visible-light digital images of all critical gearboxes that are running hotter than normal.

Look, too, for leaking seals. Thermal images can reveal hot oil running down gearbox cases.

Be aware that while all excessive heat generated in mechanical gearboxes is the result of friction, it may have a source other than inadequate lubrication. For example, its source might be friction caused by faulty bearings, misalignment, imbalance, misuse, or just normal wear. Thermography is a good first step toward a complete analysis of a critical gearbox’s condition.

Troubleshooting gearboxes When you find an overheating gearbox, its thermal image may offer hints as to the cause of its abnormal operating temperature. For example, if an oil pump has failed, its inlet and outlet temperatures will be the same. But whatever the suspected cause of overheating, maintenance personnel can arrange to follow-up by checking the oil level, oil quality and metal-particle content of the oil, or perform acoustical testing or vibration analysis.

In general, it is a good idea to create a regular inspection route that includes all critical motor/drive combinations.

Then, save a thermal image of each one on a computer and track measurements over time, using the software that comes with the thermal imager. That way, you’ll have baseline images to compare to, that will help you determine whether a hotspot is unusual or not, and, following repairs, help you verify if the repairs were successful.

How to avoid compressor failures A preventive maintenance program is essential for maximizing the service life of a rotary screw compressor airend. The key is to make sure your program matches your application.

BY DAN WISE

T

he oil-flooded rotary screw compressor is the most common type of compressor used in industrial plants. There are several reasons why this style of compressor has become so popular. The price of the unit and low installation costs provide the initial attraction for many customers.

In addition, the rotary screw compressor requires less maintenance over the long term. This is especially true when comparing it to a reciprocating compressor of the same size.

One primary objective of rotary screw maintenance involves monitoring the filtration system and oil change intervals in such a way that prevents outside contaminants from damaging the compressor. This helps protect the airend, which is the most expensive part of a rotary screw.

Our research into the airend aspect of the business found a company providing exceptional service and value with an airend exchange program. This company

has evaluated several thousand failed airends that were exchanged as cores for remanufactured units. It has a unique insight into the common factors that cause premature airend failure and its staff have shared the following observations.

Bearings The bearings used in a rotary screw compressor airend are expected to maintain internal clearances of a few thousandths of an inch for many years of continuous service.

These bearings will wear out at a rate dependent on many design and environmental variables. These variables include such factors as number, quality and type of airend bearings (they are not all the same), speed and pressure at which the airend is run, and provisions for filtration and coolant capacity.

Above: Contaminated lubricant causes more airends to fail prematurely than any other factor.

Right: Normally, compressor manufacturers quote an average airend bearing life expectancy of 40,000 hours or more.

Left: All compressors need ongoing preventive maintenance.

Normally, compressor manufacturers quote an average airend bearing life expectancy of 40,000 hours or more. This is equivalent to five years or more of 24-hour-per-day duty. You must avoid some of the causes of premature failure if you are to achieve this longevity.

Contaminated lubrication Contaminated lubricant causes more airends to fail prematurely than any other factor.

Air compressors ingest airborne contaminants every minute they are operating. Inlet filters slow the process but usually only catch particles over 20 to 30 microns. Also, they do nothing to stop chemical vapours that can attack the lubricant as well as the compressor.

Any particles smaller than the micron rating of the inlet filter will enter the airend. In addition, when the filter begins to plug, dirty air can suck past the filter gaskets, pulling larger debris inside.

ent models from the same supplier.

It is not likely that you will find a recommended oil injection pressure in the compressor manual. Injection pressure is the sump pressure minus the pressure drops through the cooler, oil filter, piping and any valves in the lubrication system.

On a typical 100-psi unit, you will usually see oil injection pressure at 70 to 80 psi when the compressor is under loaded conditions. Lower injection pressure is a key indicator of a problem that can cause major damage to the airend.

An inspection will be required to find the source of the pressure drop.

Lack of oil flow at start-up If there is little or no lubricant supplied to an airend on start-up, the bearings may last for hours. However, within minutes (or less), the rotors will lose critical discharge end clearances and seize.

Failures of this type are most often due to a complete blockage in the oil flow.

This could be a bad oil stop valve or oil pump (where applicable). It could also

Advanced lubricants have made it possible for extended operation between oil changes. However, you must not assume that your lubricant will remain clean for those advertised 8,000-hour oil change intervals.

Some oil filters have a pressure bypass designed into them to prevent oil starvation should the filter element become plugged. Usually, these operate at from 15 to 30 psig of pressure drop.

In extremely dusty installations or environments, this can occur consistently within a week of filter replacement. Oil analysis and careful monitoring of compressor vital signs must accompany extended oil change intervals.

Lubrication flow to the airend The lubricant injected to the airend serves the important function of removing the heat of compression. This refers to the heat released when the air or gas is compressed. As an example, a 100 hp rotary screw compressor will typically generate from 250,000 to 400,000 BTUs of heat per hour of running time.

In the 1980s, most compressor manufacturers simplified the design of the rotary screw compressor to eliminate the oil pump. This means the compressor must rely on sump pressure to inject oil into the airend.

Compressor lubricant flows from the sump to the cooler before going to the oil filter. The oil is then piped from the oil filter to the injection ports of the airend.

There is no reservoir between the oil filter and the airend. Any blockage in the oil filter, oil cooler or within the oil piping system will lower the pressure of the oil supplied to the airend or reduce the oil injection pressure.

The amount of oil pressure combined with the size and location of the injection ports will determine the oil flow you have available to remove the heat of compression. This means normal oil injection pressure may vary between brands or even within differ-

mean that there is an obstruction in the oil filter, oil cooler, oil piping system or in any valves within the lubrication system.

In these failures, it is common for the compressor to run for several minutes before seizure. The following are a few indicators of an impending problem: 1. The compressor is making very little compressed air. Lubricant is also required to seal the rotors to each other and to the airend housing.

2. There is no hot air blowing from the

oil cooler. Normally, within very few minutes, a significant amount of heat is released into the cooler by the circulating lubricant.

3. The oil piping system is not getting hot, since no lubrication is returning to the airend. A compressor package with a thermostatic bypass valve will circulate lubricant from the airend to the sump through the thermal valve, oil filter and back to the airend until the lubricant reaches operating temperature.

Heat should be present throughout the piping system.

4. The discharge side of the airend is getting very hot. Don’t rely on oil temperature shutdown switches to protect against lubricant starvation. If there is no lubricant flow, hot oil temperature switches and even some hot air temperature switches may not function properly.

5. All new or remanufactured airends should be primed with lubricant at start-up to help begin the oil circulation. This procedure alone is not likely to prevent this type of catastrophic failure. However, it may give the technician the opportunity to identify a lack of oil flow before it becomes a problem.

In the early stages of build-up, varnishing begins to give the compressor oil a burnt smell. This can be noticed when checking or adding lubricant as recommended in the owners manual. However, the recommended approach to identifying the problem is to perform regular oil analysis.

The oil analysis will reveal the high acid number and increased viscosity associated with a varnish problem before it becomes severe. You can also use an analysis to monitor many other issues that affect compressor service life.

A major concern is the effect that varnishing has on the other components of the compressor package. It is well accepted that even small amounts of varnish left in the oil system will accelerate more varnish formation in the future.

All components coming in contact with compressor oil need thorough cleaning. This includes the oil cooler, sump, oil lines, thermal valve, oil filter assembly, oil stop valve or oil pump where applicable.

A de-varnishing agent may also be added to the fresh oil at startup. However, be prepared with more fresh lubricant and replacement filters. Any varnish deposits left in the oil system will break loose and collect in the filters, causing them to plug up and begin the cycle over again.

This article is part of an ongoing series.

The introduction appeared in Machinery & Equipment MRO’s February 2005 issue and the series has run in every issue since. Previous instalments are archived online at www.mromagazine.com. In this issue, we pick up where we left off in the September 2009 edition, as maintenance manager Bob Edwards and members of his team begin to implement what they learned during an information-gathering visit to a big US paper mill. We join Bob at the end of his first day back on the job.

W

hen I got home in the evening after work, I explained to Sandy, my wife, what had taken place at the mill and how I wasn’t sure if I could get Joe, the plant manager, to be the champion we needed — or even if I was the right person to try to convince him to do so.

“Well, Bob, you’re beginning to see that you need to manage both directions in some circumstances and it’s usually harder to manage up than down. As to whether you’re the right person to do it — who else? Joe has told you the corporate office is watching what you’re doing with your group, so you’re going to have the greatest influence. You’ve seen what the future looks like when you were visiting the mill in Wisconsin, so whether you like it or not, you’re going to have to guide the rest.”

“That’s part of the problem — I’m not sure I know how to get there. I’m not sure that I’m up to doing all of this.”

“You’re forgetting one important thing — something you seemed to have figured out before — you’re not alone.

You have your reliability manager, Carol, who seems to know everything about the technologies and is not afraid to challenge the status quo. You have the millwright, Stan, who, because he didn’t believe but does now, will give support and credibility. Then there’s Dave from plant services, who’ll take whatever you give him and run with it. And I’ve heard you talk about the other millwrights, Pete and Ivan, as wanting to take responsibility — so let them.”

“Thanks, Sandy. You’re right, of course. In fact, I think that group is better prepared for this than I am. It still leaves Joe and the production manager, Fred — and his production group — who all need to be part of this.”

“As far as they are concerned, you need to show them how it’s important for them and then they’ll join in. I remember reading a quote from Dwight Eisenhower that went something like: ‘Leadership is the art of getting someone else to do something you want because he wants to do it.’ So you and Joe have to become the leaders.”

With Sandy’s words firmly implanted in my mind, I set off for the mill the next morning, where I knew I had to pull a team together to set up our plan. I called Carol and asked her to bring Stan up to my office so we could go over the highlights of our US trip before we rolled out a presentation to the rest of the maintenance group.

When they arrived, they both seemed excited and eager to talk about the trip.

“Did you see how well the shop was set up?”

“Their work order system! Wow, imagine! It’s set up to communicate to everyone automatically — and then there were those KPI calculations.”

“I’m glad you’re both enthusiastic,” I said.

I then told them about Sandy’s comments and how they would be crucial to

How much would he involve me? But the fact that he had acted so soon was encouraging. After I had given Carol my report, I went down to the shop to see how the day was going.

Dave was in the shop rebuilding a wastewater pump.

“Hi Dave, what happened with your modification? Did it hold up, or is this a different failure?”

“No, in fact it’s the opposite. The pump is working fine. This is the spare to which I’m adding the modified back plate that the manufacturer sent us for free. In fact, they sent us a complete spare parts kit for free!”

“Hey, that’s a good deal. Thanks for your effort, Dave.”

“It’s not as good as it seems, Bob.” “Why do you say that? We’ve spent quite a bit of money on these pumps, so everything will help.”

“That’s right, Bob, but that was before I came up with the solution. This kit will be sitting in the stores gathering dust — if not, you can transfer me to stock prep.”

“Wow, given how much you dislike the stock prep area, you must be pretty confident.”

“How was the mill in Wisconsin?

Stan’s been pretty tight-lipped about it.

I’m not sure he was the right guy to go after all.”

“No, Dave, your suggestion that he go was inspired. We hope to have a meeting tomorrow to talk about the trip. We just want to make sure we captured everything and that everyone gets the same message. One of the things I can say is that in the environment we saw there, you would have a great time. We’re going to try and get that environment here.

“Not only will you enjoy it, you’ll also be very instrumental in creating it. One lesson we learned was that we need to create a situation where everyone can reach their potential, irrespective of position and title. And as we’ve talked about before, I’m not sure if even you know your potential.”

“Sounds good, Bob. It seems like something to look forward to.”

I headed up to the meeting room for Joe’s gathering, to find Fred, Debbie and Josh already there.

“This must be important,” claimed Josh.” I had a meeting already booked for this time but Joe told me to get someone else to attend as this was one meeting I wasn’t allowed to miss.”

Just at that moment, Joe arrived and set up his presentation, which he had entitled ‘The Way Forward’.

“All right everyone, this might seem a little bit sudden, but I’ve been talking with corporate over the past few months and they’ve repeatedly told me that as a company, we need to get more efficient, production- and cost-wise. They’ve watched what Bob and the maintenance group have been trying to do and have committed money to support their move toward condition monitoring.

“This is a good start but it’s not enough, so I’m going to sponsor a new program called Project 600. We’ll look at what is preventing us from producing 600 tonnes per day and then each of you will sponsor projects within your departments to get us there.”

Joe had certainly taken the bull by the horns. I couldn’t wait to hear more. MRO Cliff Williams is the corporate maintenance manager at Erco Worldwide in Toronto, ON, and a consultant with TMS — Total Maintenance Solutions Inc., Markham, ON. He can be reached by e-mail at williamscliff@rogers.com.

dvanced CMMS modules can be used to record measurements you take on critical equipment, and some CMMS programs are able to take the measurements for you and analyze the data. Surprisingly, there are not many programs that will create trend reports and graphs that use statistical tools to create charts that show the results of measurements taken over an extended period of time.

Machinery that must run in order to produce your end product often receives a lot more attention than other redundant equipment in the process.

For example, a gypsum quarry near my home monitors its main conveyor systems and crusher with vibration analyses, as well as temperature and motor amperage measurements.

These readings are taken at regular intervals and are set up in its CMMS, which prints the predictive maintenance work orders. The vibration analysis is contracted out to a local contractor. Once the measurements have been taken, the contractor prepares a comprehensive report on the condition of the rotating equipment.

Vibration analysis provides a longterm picture of the condition of the equipment and identifies problems very early in the machine’s life cycle. Any suspect equipment can be more closely monitored and repairs can be scheduled when the plant is down.

This particular vibration analysis company has very sophisticated equipment and the software it uses analyzes the data and creates trending graphs and quickly identifies impending equipment failures. A complete report is sent to the plant. A work order is then created and parts obtained to complete the repair.

There exists other, less-sophisticated vibration analysis equipment that only provides a reading on the unit itself and identifies the condition of the equipment at that given time. It offers no software to do a trend analysis from previous measurements. Many facilities have purchased these units over the years, as they are fairly inexpensive. They show if the equipment either passes or fails.

Sometimes the measurement tool simply shows red, yellow or green to indicate the equipment condition.

The same holds true for temperature and motor amperage measurements.

Although these two readings provide on-the-spot, at-the-moment, numerical values, they are not often compared to

previous measurements; the temperature or motor amperage either falls into an acceptable range or it doesn’t.

So what if your CMMS could take these readings and do the analysis for you? There are CMMS programs that enable you to enter the values you record.

It will then analyze the data based on the parameters you set in the program.

One CMMS that does this very well is an Infor product called MP2.

The Statistical Predictive Maintenance (SPM) module goes beyond preventive maintenance into a predictive mode by identifying equipment readings outside preset control limits, alerting you to schedule maintenance before the equipment fails.

For example, you may create a SPM record that monitors amperage readings

of a 100-hp rock transporting conveyor.

First you set the minimum and maximum possible readings for the motor, as obtained from the manufacturer’s specifications. Then you would enter each reading in the equipment record and periodically generate reports and graphs to recognize trends and readings that fall outside the specified range.

The MP2 software also automatically generates a repair work order when readings fall outside predetermined SPM limits. The software lets you choose the type of analysis you prefer. Use the manufacturer’s minimum and maximum values or use Standard Deviation Calculations for a more sophisticated Statistical Process Control (SPC) to produce charts (see graphs below).

In other CMMS programs, you can

Machinery & Equipment MRO

input the specifications of a piece of machinery. For example, the temperature of a motor should fall between two values that create what is called a ‘condition’. This condition is then transferred to the predictive maintenance work order, where the craftsperson can then note the temperatures on the work order and visually see from the normal condition whether the measurement passes or fails. A report can then be created to view the trend of the readings.

Your CMMS may have one of these SPM features. Predictive maintenance, sometimes called just-in-time maintenance, demands regular monitoring but can provide substantial cost savings by delaying maintenance until failure is imminent.

For example, by reading and analyzing vibration readings on a rock conveyor, you can extend the useful life of the part without risking downtime on the equipment.

I know that many facilities struggle to get just the basic information recorded in their CMMS. Getting PM work orders generated and distributed to the craftspeople, and retrieving and completing them properly in the software, are about all they can manage.

However, as they improve their preventive maintenance program and get breakdowns and repairs under control, there will be time to be more proactive in this area.

Using a CMMS SPM module will get you into predictive mode and provide an even higher level of service to operations.

As a reminder, we are getting close to the end of 2009. Last year, in the December issue, I wrote about the ups and downs of previous year. I’ll be doing it again this year. If any MRO Magazine reader has stories about successes or challenges implementing a CMMS during 2009, I really would like to hear from you.

How will maintenance get done with a flu outbreak?

BY SIMON FRIDLYAND

We all hope that a pandemic will not affect us, however we need to be ready should it arrive.

T

he flu season is upon us. Scary headlines about H1N1 — the swine flu virus — appear in the media almost daily. The infectious pandemic obviously should be taken seriously, because it could affect our health, our employment and a company’s business performance. In order to deal with the issue, we need to understand the basics and develop a plan of action.

A pandemic occurs when a new strain of virus spreads around the globe, infecting many people at once. The reason it spreads quickly is because it is a new virus and people have no immunity to it. The World Health Organization suggests that the H1N1 flu virus has the potential to infect 25% to 30% of the world’s population.

A pandemic like this may: • arise rapidly and spread quickly • make people very ill; many likely will die • generate unprecedented levels of fear and panic • occur in several waves, each lasting for several months • require government, businesses and many community agencies to be involved in a whole-of-society response • result in health care services not being able to provide direct care in some cases, and • result in very high staff absence rates for some periods during the pandemic.

With these factors in mind, your company will need to develop contingency plans to manage the impact of a potential pandemic on its business.

The contingency plan should consist of the following points: 1. Identify your business’ core people and skills.

What are your business’ core activities, who carries out the essential roles and what skills do they need? How might your business operations be affected by a 30% to 50% drop in staff at the peak of the pandemic? Will you be able to maintain your equipment and keep your machines running?

2. Consider the effects of supply shortages on operations.

Are there any products or external suppliers that are essential to your business functions? What would you do if you couldn’t access these products or people?

Can items you need be stockpiled or sourced from another supplier, distributor or buying group?

3. Plan for staff absences.

Arrange for staff to learn other peoples’ jobs, especially the important ones, so that there are a number of people who can backfill the positions of those who are away.

4. Consider human resource issues.

Update leave policies (e.g. sick leave, carergivers leave and other provisions) and advise staff about staying away from work if they are ill during a pandemic. Concern about lost wages might make it difficult for some to stay at home, even if they are sick.

Staff might also need to stay home to care for family, particularly children.

5. Decide if your business will stay open or will close in a pandemic.

Remember, if you provide an essential service for community functioning, you should make every effort to stay open. Businesses that are considering a temporary closure should examine their insurance policies (especially Loss of Profit insurance) and consult with their insurers before making a decision to close during a pandemic.

If you are not a key service provider, you will need to consider at what point you might close temporarily. If you do stay open, your business planning might include consideration of employee risks and your duty of care as an employer.

Will you need to rely more on online or phone services? Does your business have the necessary infrastructure to cope?

You should also consider that there may be interruptions to services such as power or telecommunications.

6. Encourage good personal hygiene practices.

You don’t need to wait for a pandemic to practice good hygiene that could reduce the spread of infection. Encourage proper coughing/sneezing etiquette and ensure you have a good supply of handwashing products in stock. Your business premises, especially hard surfaces such as doorknobs, sinks, railings and counters, should be cleaned regularly.

You should also ensure you have a wellventilated work area and check that your air conditioning is serviced regularly.

7. Understand social distancing measures.

In a pandemic, staff should be encouraged to minimize contact with others.

This might include restrictions on congregating in staff rooms. During shift changeovers, you could have one shift leave before a new shift begins.

8. Communicate your plans to staff and customers.

In the lead up to and during a pandemic, your staff will likely be concerned about and be preoccupied with the wellbeing of their families. Their commitment to their jobs or their ability to work may not be their major concern. Staff and customers will feel reassured by your pandemic planning activities and will be

pleased to know you are thinking ahead, and are preparing as best you can.

Tell your staff about your expectations of them during a pandemic (i.e. to report any illness and not to come to work if ill).

9. Look at the financial implications.

Think about how a downturn in business might affect your business’ cash flow.

Do you have some cash reserves? Remember that credit facilities might be limited.

10. Test your plan and know when to use it.

Once you have developed your continuity plan, it is worthwhile to test it.

This way you’ll know how well it might work in a real situation and if you have overlooked anything. Decide when you will activate your plan.

In order to minimize the spread of the virus, special attention must be paid to the following points: Hand washing • A dopt good hand washing/hand hygiene practices, particularly after coughing, sneezing or using tissues.

• Immediately dispose of used tissues.

• Keep hands away from the mucous membranes of the eyes, nose and mouth.

• Ensure that adequate supplies of hand hygiene products are available. (This is a high planning priority as there may be an interruption in the supply or shortages of soap and hand towels).

• Have a supply of tissues available and provide no-touch receptacles for used tissue disposal.

• Consider having conveniently located dispensers of alcohol-based hand sanitizer.

• Provide soap and disposable towels for hand washing near all sinks.

Coughing and sneezing • Cover the nose and mouth when sneezing and coughing (preferably with a disposable, single-use tissue).

• Dispose of tissues in the nearest waste receptacle after use. Do not store them in your pockets.

• Wash your hands after coughing, sneezing or touching used tissues.

Personal protective equipment (PPE) • The most commonly used PPE equipment would be masks and protective barriers. Disposable masks help prevent exposing others to respiratory secretions of those who are ill. Dispose of any mask as soon as it becomes moist or after any cough or sneeze, and wash the hands thoroughly.

• Protective barriers in the form of Plexiglas or glass may provide useful protection for people such as front counter staff,

whose duties require them to have frequent face-to-face contact with members of the public and where social distancing is not practical.

Social distance • Businesses should use the concept of social distancing at work. If possible, teams should split into different work locations to allow for a backup team and to help prevent cross-infection.

• Avoid face-to-face meetings, even at work (use telephone conferencing).

• Avoid public transportation.

• Bring and eat lunch at your desk; don’t use the cafeteria or at least use staggered lunch times to avoid large numbers of people congregating.

• Cancel non-essential training sessions and meetings.

• Shift changes should be managed in a way to prevent cross-contamination, i.e. provide an interval before the next shift begins; this helps reduce the number of people meeting in the locker room, etc., and provides an opportunity to ventilate the work site during the shift change (windows opened, increased HVAC).

• If face-to-face meetings are absolutely necessary, try to use a large room and sit at least three feet apart.

Cleaning • There’s no doubt that cleaning should be enhanced during a pandemic.

• Disinfecting solutions should be applied to all common area surfaces, such as counters, railings, sinks, shared telephones, shared computer keyboards and toilet bowls.

HVAC • HVAC systems should continue running, but try to increase the amount of outside air and reduce recirculation.

There is no clinical indication for cleaning air filters during a flu pandemic.

Since the spread of flu is still primarily by droplets, thus is not airborne, filters will not make a difference. Additionally, most industrial HVAC filters will not filter virus-sized organisms anyway.

We all hope that a pandemic will not affect us, however we need to be ready should it arrive.

Industrial show unveils innovative products, services Toronto, ON — From three-dimensional printers that turn ideas into hand-sized plastic models and laser systems that cut more parts in less time using less energy, to new developments in smart robotics, exhibitors at the Canadian Manufacturing Technology Show 2009 (CMTS 2009), held in Toronto Oct. 19-22, 2009, unveiled technological innovations available to manufacturers looking to reinvent their businesses on the heels of the economic downturn.

“More than 60% of Canadian manufacturers see their business increasing over the next 12 to 18 months,” said Mark Tomlinson, executive director and general manager of the Society of Manufacturing Engineers (SME), organizer of CMTS 2009.

A showcase for the latest machine tools, automation technologies, metal forming, measurement technologies, tooling solutions, production methods and management strategies, the event included a comprehensive exhibitor showcase, Town Hall meetings, panel presentations and a simultaneous technical conference called Automation Rendez-vous 2009.

“This is where they come to evaluate, purchase and compare the technologies that will take their business to the next level,” said Tomlinson, noting that manufacturing remains Canada’s largest business sector with more than $594 billion in manufactured goods and in excess of $400 billion in exports each year.

The exhibitor portion of CMTS 2009 featured a roster of more than 500 Canadian vendors, including such exhibits as: • The first North American demonstration of the TRUMPF TruLaser 303, an

innovative laser cutting machine that cuts more parts in less time, while consuming less energy.

• Automation Cell Live, a premiere event designed to display the latest developments in factory automation using real world settings. Representing a mini replica of a factory floor, it demonstrated the latest in smart robotics, including robots used for high-volume welding and cutting applications, as well as robots equipped with infrared vision systems that enable them to perform tasks normally carried out by humans.

• A Green Solutions Program featuring products designed to help manufacturers make their operations more environmentally friendly, including a heat exchanger that recycles heat from outgoing air, oil purification technology, an eco-friendly cutting fluid that extends the life of cutting tools, large ceiling ventilation fans that use 20% less electricity, and an electromagnetic control system that reduces the amount of non-productive current in electrical systems, helping to reduce electrical costs.

• Three-dimensional printers, including the uPrint Personal 3D Printer from Dimension and Simulate Complete from StampingSimulation.com, which turn ideas into durable plastic models users can hold, discuss and test right at their desk.

• Hearing protectors that custom fit to individual workers; high-performance plastic screws, nuts and bolts; a programmable band saw that stores up to 20 cutting jobs at a time; the latest in mobile communication technology; planning software that optimizes distribution centre inventory; new machine monitoring and control techniques, and more.

UNMATCHED ENGINEERING EXCELLENCE FROM THE SCHAEFFLER GROUP Spherical Roller Bearings T41D Vibrating screens for grading material and other machinery where vibration stress exists are among the most severe bearing conditions encountered in machinery construction. For a number of years Schaeffler has offered special design FAG E1 spherical roller bearing with specification T41A to accommodate the punishing operating conditions found in vibrating machinery such as: • high loads and high speeds • high radial accelerations • revolving shaft deflections • sliding motion within the bearing In order to prevent fretting corrosion between the bearing bore and the shaft, Schaeffler now offers the same series and design of spherical roller bearings with a thin-layer chromium plated bore (specification T41D). This coating ensures that the displacement ability (floating bearing function) between the bearing and the shaft – necessary

due to thermal influences - is maintained for a long period of operation.

With the addition of thin-layer chromium plating, FAG spherical roller bearings for vibrating screens offer unparalleled operating benefits: • highest load carrying capacity • supports heavy shock loads and radial acceleration • no fretting corrosion • unhindered thermal shaft expansion • prevention of shaft damage • longer service life

Hydraulic Extractors PowerPull SPIDER Hydraulic extractors PowerPull SPIDER are used where higher extraction forces are required that preclude the use of standard mechanical methods and devices. The 10 available extractor sizes have a range of extraction forces from 40 to 400 kN, covering a very wide range of possible applications.

These devices allow rolling bearings, gears, sleeves and many other shrink fitted parts to be quickly and easily dismounted. In addition, the light weight of the extractors mean that they can be used in virtually any position.

Through Rock-Solid Obstacles The combined technologies of INA and FAG offer the broadest possible range of bearing solutions to guide mining and processing machinery and equipment through the most demanding operating conditions.

From standard bearing products to highly specialized application solutions, including monitoring and maintenance services, INA and FAG commit decades of innovation to optimizing the performance of boring and excavation machinery, hoisting and conveying equipment, grinding mills and vibrating screens.

Operational reliability and cost-effective innovation from INA and FAG – bearing solutions that move the earth.

SCHAEFFLER GROUP

If necessary, greater grip depth can be achieved through the use of extra long extraction arms (available integrally if specified, or separately as accessories).

For protection of operators, the extractors SPIDER 40 to 80 have a safety grid. All larger hydraulic extractors are supplied with a transparent, tough safety cover to capture any parts that may fly off under extreme load. All parts under load are made from high quality chromiummolybdenum steel, and an integral pressure control valve prevents overload of the extractor.
