Rugged handheld analyzer identifies scrap/ recycled metal

Oxford Instruments has added the mPulse handheld analyzer to its product line. Designed for the metal recycling market, the

instrument uses Laser Induced Breakdown Spectrometry (LIBS) and combines 1-sec. analysis speed with ease of use and rugged reliability. This scrap metal analyzer has been designed to allow quick, simple and reliable identification of scrap or recycled metal and determine its value, minimizing time and maximizing profits. It can be used to test large or small samples, including turnings and granules. The laser scans the surface of the sample and will bounce repeatedly across tiny samples to optimize the analysis. Samples can be held where convenient because the laser is microscopic, non-penetrating and cannot be felt. This is a surface analyzer so test pieces should be clean, but no specific sample preparation is normally needed. Anodized surfaces will usually be penetrated by the laser.

Bearing assembly improves safety of oil rig maintenance personnel

A bearing that helps increase safety and improve uptime on oil rigs has been introduced by Timken. Designed to eliminate the need to re-grease the travelling block or crown block on oil rigs, the Sheave Pac bearing assembly is sealed for life, helping to increase safety for rig workers and reduce expensive downtime.

The pre-greased, pre-set and unitized bearing can run an entire operating cycle between rebuilds without the need for re-lubrication or additional maintenance, and the assembly easily interchanges with current industry-standard bearing assemblies and seals.

Laser vibrometer performs acoustic inspections of noise-critical equipment

The non-contact SKF laser vibrometer (MSL-7000 series) measures vibration and structure-borne noise from fans, electric motors and pumps for every measurement surface, regardless of environmental conditions. This digital, singleunit laser tool cannot wear and does not require servo-mechanisms or noise protection gear during use. It can cover acoustic measurements from 0.2 Hz up to 22 kHz and can integrate easily into a manufacturing line and existing control systems. This integration can create a real-time quality control system for products enabling pass/fail decisions on the basis of structure-borne vibration. The vibrometer further supports flexible re-setting of manufacturing batches and test set-ups.

It can be combined in the field with SKF Microlog portable vibration monitoring and data collection instruments. A special package, the MSL-7000C, developed for laptop use with SKF FPM software and a mobile data acquisition card, also is available.

ECONOMIC GROWTH IN ALBERTA EXPECTED TO LEAD CANADA

ditures with resource revenue helps to keep provincial tax rates low. But a large decline in royalties, such as what occurred in 2008-09, would make achieving and maintaining a balanced budget much harder.”

Economic growth in Alberta is expected to be the strongest in the country in 2014 and 2015. Real GDP will rise by 3.5% in 2014 and by 3.1% in 2015. Strong economic growth will continue to fuel gains in employment and income, further increasing the government’s tax base.

As a consequence, Alberta is one of the few provinces set to have balanced books in 2014-15, along with BC and Saskatchewan. In addition, Alberta is the only province with a net surplus of financial assets. This implies that interest payments on debt will be negligible over the forecast period – a feat that no other province will accomplish.

While the Conference Board is projecting annual surpluses for three years starting in 2014-15, there are risks to the outlook: the potential constraints on economic growth if pipeline development stalls and the ability to limit growth in health care spending.

PTDA MEMBERS SAW GROWTH IN NEW ORDERS IN SECOND QUARTER Chicago, IL – The PTDA Business Index for the second quarter of the year (2Q2014) indicates strong growth in both business activity and new orders. From 1Q2014 to 2Q2014, business activity of distributor and manufacturer members of the Power Transmission Distributors

Association increased 12.7% (from 67.7 to 76.3) and new orders improved 14.5% (from 67.7 to 77.5).

This quarterly survey continues to point to growth, with the 2Q2014 Business Index at 68.7, up from the 1Q2014 reading of 63.6. However, when asked about their outlook for the entire year, survey participants’ expectations remained the same as the previous quarter at 6% growth.

The index reading indicates the rate of change compared with the previous period. For example, a reading of 50 indicates no change from the prior period, while readings above 50 indicate growth and below 50 indicate contraction. The further the index is above or below 50 suggests a faster or slower rate of change.

FOR HIGHEST SALARY INCREASES IN CANADA, LOOK TO THE OILPATCH Calgary – For the biggest pay hikes in Canada, look no further than the oilpatch. A new survey by Mercer, a global consulting firm, says the energy sector is leading the country in both actual and projected salary increases.

The average base salary increase across the country is expected to be 3% next year, the same as in 2014. But in the energy sector, the pay bump is forecast to be 3.7% in 2015 after an actual 3.9% increase this year.

When the energy sector is removed from the national sample, the average projected salary increase drops to 2.9%.

On the other end of the spectrum, transportation, equipment, consumer goods and retail/wholesale industries are expected to see the smallest salary increases. The Canadian Press

CO-OP DIPLOMA APPRENTICESHIP PROGRAM TO PROVIDE NEW MECHANICAL TECHNICIANS Oakville, ON – Sheridan College is offering a three-year Co-op Diploma Apprenticeship program in Mechanical Technician-Tool Making to make it easier, cheaper and faster for individuals to pursue in-school and on-the-job training in a sector that is poised to grow, according to a 2014 Outlook Report by KPMG. The seamless program enables individuals to train as apprentices, completing all in-school learning outcomes and significant on-the-job training, while concurrently obtaining a post-secondary diploma.

“Students complete a year-long, paid work experience in which they develop in-depth tool-making skills while accumulating up to 2,000 hours toward their apprenticeship,” said Alan Reid, associate dean of Sheridan’s Skills Training Centre in Oakville, where the program is based. “[Since] an employer consortium sponsors all participants, the program is available even to students who lack a

Ottawa – After six years in the red, Alberta is expected to balance its books in 2014-15, according to The Conference Board of Canada’s Alberta Fiscal Snapshot: Promising (But Potentially Risky) Prospects.

“Overall, Alberta is in a very sound position and our forecast for Alberta is even more optimistic than the government’s own budget projections, thanks to an expectation of higher resource revenues,” said Matthew Stewart, associate director, Canadian Outlook.

“Perhaps the greatest risk to Alberta’s future is its high reliance on royalty revenues to fund program spending.

“Without tool making, there is no manufacturing,” noted Reid. “Every time you change the shape of any product that is mass produced, a new tool is required.

This is the talent we’re cultivating at Sheridan. We’re building the foundational expertise that companies need to manufacture their products or make production happen, whether they operate in the pharmaceutical, automotive, electrical components, medical, food or aerospace industry.

“Our biggest challenge at Sheridan is that we have five times the job offers as we do graduates to fill them.”

BELTING GROUP AND PTDA TO HOLD JOINT MEETING IN 2017 Chicago, IL – The boards of directors of NIBA-The Belting Association and the Power Transmission Distributors Association (PTDA) are planning to hold a joint annual conference. The NIBA/ PTDA Joint Industry Summit is to take place in the fall of 2017.

The leaderships of both associations have dedicated much effort in designing a program that will continue to provide the exceptional experience already

enjoyed at each organization’s current annual meeting, as well as bring enhanced benefits that are only possible through a joint conference.

With the NIBA/PTDA Joint Industry Summit, members of both associations can expect enriched networking opportunities, enhanced educational content, and minimized conflicts and reduced multiple meeting attendance costs for shared members.

PTDA president Ken Miko, director of category management and strategic accounts for BDI, Cleveland, OH, believes the NIBA/PTDA Joint Industry Summit will bring membership innovative new ideas. “We set out to create an event that is truly a joint event – that is, maximizing the opportunities for members of both associations to meet and discuss their businesses,” said Miko.

NIBA president Tom Wujek, executive vice-president and chief operating officer of Flexco, Downers Grove, IL, agrees. “We took the best practices from each organization’s annual meeting and crafted a conference that elevates networking and education to a whole new level,” he said.

BEARING FIRM PARTICIPATES IN US COUNTERFEITING RAID Mt. Prospect, IL – NTN has announced the results of a joint raid that it participated in with the US Naval Criminal Investigative Service (NCIS). The raid was conducted on a bearing storage location near Charleston, SC, on June 25, 2014, after NCIS agents concluded that the warehouse was illegally distributing lowquality, counterfeited bearings directly to end users.

The search resulted in the seizure of hundreds of fake NTN products, as well as counterfeited merchandise of several other major Japanand US-based manufacturers.

The investigation was coordinated by NCIS and included engineers from major bearing corporations that volunteered to aid in the identification of the counterfeit parts. NTN application engineers supported US Naval agents in detecting suspect products and packaging with fake NTN company logos.

All of the suspicious products were confiscated and catalogued to assist in future prosecution and investigation of illegal bearing counterfeiting.

APPRENTICESHIP TRAINING INCREASING ACROSS CANADA Ottawa – Apprenticeship training programs across Canada received 104,280 new registrations and reinstatements in 2012, up 6.8% from 2011, according to the latest survey of registered apprenticeship training programs from Statistics Canada.

This marked the highest number of new registrations and reinstatements (individuals who were reinstated in 2012 after a year or more of absence) since the beginning of the economic downturn in 2008.

Total registrations in apprenticeship training programs across Canada increased 4.3% from 2011 to 444,672 in 2012.

New registrations in the Red Seal trades were up 6.8%, but the number remained below 2008 levels. New registrations in non-Red Seal trades

were up 11.5% from 2011.

In 2012, 56,913 certificates were awarded to both apprentices and trade qualifiers/challengers, up 2.7% from 2011.

The number of new registrations in the construction electrician trade has increased every year since the end of the economic downturn. The steamfitter/ pipefitter trade (+45.7%) posted the largest annual increase in new registrations in 2012, followed by the welder trade (+41.7%), where the number of new registrations exceed those recorded in 2008.

The proportion of females registered in trades has been constantly increasing over the years. In 2012, females accounted for 14.2% of all registrations.

The highest number of new registrations for females was in the user support technicians major trade group (4,095), where for the first time, new registrations exceeded those in the hairstylists and estheticians group.

ELECTRICAL INDUSTRY COUNTERFEITING SURVEY REVEALS PARTS REPORTING ISSUE Arlington, VA – The Electrical Safety Foundation International (ESFI) has released the complete results of its 2014 Counterfeit Electrical Products Survey, which was developed to measure the awareness and response to the presence of counterfeit electrical products among several sectors of the electrical industry.

The results reveal critical information about the observations, attitudes and perceptions of those who manufacture, distribute, install and inspect electrical products.

Over the past decade, US seizures of counterfeit products have increased more than 325%. Consumer electronics were the top commodity seized in 2011, with a value of nearly $40 million.

Counterfeit electrical products pose significant safety hazards if left undetected, and have been known to cause deaths, injuries and substantial property loss in the home and the workplace.

“Counterfeit electrical products don’t just have serious implications for the electrical industry, but they also endanger everyone who uses electricity,” said ESFI president Brett Brenner. “We developed this survey to better understand this complex problem so we could mobilize the electrical industry to work toward a solution.”

An overwhelming 96% of respondents believe that counterfeits are at least a moderate threat to public safety, yet only half reported a counterfeit electrical product upon discovery. Further, a strong majority of respondents reported that they do not have a process in place to report a counterfeit product. Other key findings included: • Almost 55% of respondents believe their company does not provide adequate training about the issues related to counterfeit products.

• Those who have discovered a counterfeit electrical product reported finding five, on average, in the past 12 months.

• Lighting, breakers and ‘other’ items such as appliances, signs and ground rods were the most frequently reported counterfeit products discovered.

“Effectively combating the counterfeit electrical product problem will require a collaborative effort among stakeholders from all industry sectors as well as cooperation from consumers.” said Evan Gaddis, president and CEO of the National Electrical Manufacturers Association.

The complete results can be viewed at esfi.org.

protection. The year’s accomplishments show that NSK saved 39,200 trees, equivalent to 485,688,000 sheets of newspaper; 3,891,400 litres of oil, enough to heat 6,456 homes for a year; 58,880,000 litres of water, enough to meet the daily needs of 207,413 residents in the US; 201,762 litres of gasoline, enough to drive a mid-size car 2,401,785 km; and 52,938,000 kWh of electricity, enough to power 6,456 homes

for a year. “NSK’s commitment to corporate social responsibility and our corporate environmental policy initiatives are producing meaningful results,” said Brian Lindsay, CEO. “The ongoing addition of new initiatives to complement our sustainability program continues to improve those results year over year.

Ultimately, that benefits the global environment and the health of the local communities in which we operate.”

Marcia Fournier, environmental and chemical manager, and the NSK’s frontline green ambassador, said the company has a master agreement with Safety-Kleen, which not only ensures responsible waste management and disposal, but enables NSK to track any issue that may arise, and quickly mitigate environmental risk. “In 2012, Safety-Kleen worked with us to help us better manage our mop water at our Bennington, VT, site, and now we are recycling that water in-house. The result is cleaner floors, which protect our customers’ products, and less waste, which reduces both environmental impact and cost,” Fournier added.

NSK continues to advance its bearing production processes by reducing scrap waste, increasing energy efficiency and reducing the use of harmful chemicals. Steel and metal recycling is in place in all seven US sites, and a

number of sites began recycling cardboard and plastic in the past 12 months.

NSK Canada is part of this program for its three facilities in Canada and its initiatives are included in the NSK Americas report. For more information, visit nskamericas.com.

Mr.0 The Practical Problem Solver

Reducing contamination during oil changes in a dusty plant

Problem: In a dusty plant, what is the best thing to do with a gearbox plug while changing the oil?

Solution: There is no good way to handle plugs, even in the cleanest of industrial environments. Plugs not only allow contaminants to enter through the opening, but also tend to attract dirt when removed.

An additional consideration is that the threads themselves will have a tendency to produce metallic debris during both removal and installation from the shearing contact at the mating surfaces.

I strongly recommend that these units be fitted with quick-connect couplings. This will protect the lubricant from becoming contaminated from the environment while it is being introduced, and will allow for the use of a filter cart more conveniently, either for periodic offline filtration or for new oil introduction.

wo questions about manufacturing equipment frequently come to mind: “Are there any flaws in the materials or equipment that could cause them to fail?” and “What caused the defect or equipment failure?”

Non-destructive testing (NDT) addresses the first question. As the name says, NDT causes no damage. It reveals material conditions and flaws, such as cracks, changes in material strength and other issues related to material quality, life-cycle use or changes in the operating environment.

NDT includes visual examinations, non-contact surface measurements, subsurface inspections and ongoing condition monitoring (CM) that can reveal growing problems.

As for the second question, non-destructive evaluation (NDE), a term often – if not entirely correctly – used interchangeably with NDT, can be thought of as more cause-oriented.

NDE is used to study flaws and changes in equipment condition or material properties, among other things, with the goal of understanding of what caused a failure and how to prevent its recurrence.

Here are some tips on what NDT/NDE and CM have to offer.

Understand the possibilities: “If you are living in the land of ‘you don’t know what you don’t know’, the first thing you should do is acquaint yourself with the [NDT] techniques,” says Larry Cote, president & CEO, Canadian Institute for NDE. The five main categories of NDT are magnetic particle, liquid penetrant, ultrasonics, eddy current and radiography.

However, Cote notes, “Other types of NDT and CM techniques include visual inspection, and other special technologies such as digital and computed radiography, phased array and time of flight diffraction UT (ultrasound technology), air-borne ultrasound, lubricant and vibration analysis and IRT (infrared thermography), to name just a few.”

Choosing what to monitor: More than just a suite of techniques to be dusted off during teardowns or following equipment failures, NDT can be used for proactive equipment condition monitoring. “At Dofasco,” Cote recalls, “we had a methodology worked out where we would use subject matter experts to review manufacturing areas that could benefit from judicious application of NDT and CM.” In your own plant, he suggests, “Think of using a broad-based survey technique such as IRT or air-borne ultrasound. Start in one spot and ask yourself, what can you see or hear? What must you know to be sure equipment is operating reliably?

“Try and understand what the normal operating condition of your equipment is. Then consider which [monitoring]

Using fasteners effectively in

harsh environments

Proper bolt torque Proper bolt torque is required for accurate threaded-connection tension and elongation. In calculating the required torque specifications for torque tightening, a friction factor (k) is based on the fastener geometry and friction coefficients of the load-bearing surfaces (threads and bolt head). In assembly, the torque energy must first overcome friction and then create elongation to provide the clamping force.

Effective lubrication can control the friction and k-factor to ensure proper tension and elongation for the specified tightening torque. Without lubrication, too much torque is used to overcome friction, which results in insufficient elongation (or clamping force).

Lubricants are not created equal Greases, pastes and anti-friction coatings are different by design. In greases, the base oil provides the lubricating film.

Once the base oil is gone, lubrication is gone. In pastes, the base oil is simply a carrier and surface-wetting agent for solid lubricants.

Similarly, AFCs use a solvent carrier

p12-23 MRO SEPT 2014 Features.indd 13

and a resin binder to carry and adhere solid lubricants to the friction surfaces.

With pastes and coatings, effective lubrication stays in place long after the carrier fluids are gone.

Anti-seize pastes: Anti-seize pastes create and maintain a strong lubricating film that withstands extreme loads and temperatures. Both metallic and nonmetallic lubricating solids are used with a mineral oil or PAO carrier fluid. These pastes provide wear protection, consistent coefficient of friction, water washout resistance and corrosion protection.

Anti-friction coatings: Anti-friction

W

coatings are paint-like materials that cure to form a lubricating film that is unaffected by dust, dirt and moisture. Typical lubricating solids are molybdenum disulfide, graphite or PTFE. These AFCs provide dry lubrication bonded on material surfaces, resistance to extreme heat and cold, protection against rust and corrosion, and long-term lubrication for difficult-to-access parts.

Regarding application, Dow Corning’s Molykote anti-seize pastes do not require surface preparation, so they are especially

useful for application on the jobsite, while its anti-friction coatings must be applied to clean, dry surfaces, so they are normally pre-applied to parts by a coating service.

MRO This advice first appeared in Dow Corning’s Smart Lubrication Technology News.

Selecting the proper nut

hat do all the different nuts do, and which type or types do you need to purchase? Let’s take a glimpse at the world of nuts.

The essential purpose of any nut is to mate with a bolt to discourage the bolt from loosening its grip against a surface. When you thread a nut on to a bolt until it sits tight against the opposite side of the surface from the bolt head, you create a kind of stress on the threads called preload, which holds both parts in position.

What is preload? It is the tension created in a fastener when it is first tightened. The preload must be greater than the external forces applied to the assembly to prevent joint failure.

Nuts come in a wide range of sizes and shapes, though the trusty six-sided hex nut is probably the most wellknown. Some nuts have shapes that

bolt, even if that bolt is secured by a nut. How can you forestall this problem if your structure will face constant vibration during its working life? Well, you can always place a second nut innermost to the surface. This nut receives about 50% of the torque of the outermost nut, which receives full torque.

Another solution involves the use of a locking nut. Locking nuts have internal or external teeth that bite into the surface for extra grip.

Finally, there are several kinds of thread-locking adhesives available that keep bolts and nuts together.

They can convert any threaded fastener to a locking fastener. Manufacturers of such products include Henkel Loctite and Devcon Permatex.

hreaded connections are the nuts and bolts for achieving strong equipment assemblies that can beat the stress of long-term service in harsh operating environments. However, microscopic differences in threads and metals can cause uneven coefficients of friction that make assembly with the proper tightening torque difficult and disassembly without damage nearly impossible.

Proper lubrication can help improve the performance of threaded connections, allowing proper tensioning during assembly and helping to prevent stickslip, stress-corrosion cracking, fretting, galling and seizing.

Anti-seize pastes and anti-friction coatings (AFCs), with high levels of solid lubricants, help ensure a consistent coefficient of friction and withstand harsh conditions such as scorching heat, freezing cold, crushing loads, vibration, blowing sand or salt spray, and airborne contaminants.

Key functions of effective lubrication for threaded connections include: • Providing a consistent coefficient of friction to 1) help achieve proper connector preload forces and torque specifications; 2) limit effects of temperature and load variations, reducing fatigue failure rates.

• Forming a barrier between substrates and air to prevent scale formation • P roviding protective layers between mating surfaces to a) minimize oxide layer depletion to reduce fretting, galling, seizing and shearing; b) reduce stress-corrosion cracking, and hydrogen and solder embrittlement.

allow for protruding bolt heads, such as the acorn nut with its hollow cap-shaped head. Wing nuts have wing-shaped handles for easy tightening by hand.

Sometimes the shape of the bolt determines the shape of a nut. If you’re using a square bolt, for instance, you’d want a square nut.

Vibration can eventually loosen a

Demand for industrial fasteners to reach $14.8 billion in 2017

D

emand for industrial fasteners in the United States is expected to increase 4.3% per year to $14.8 billion in 2017. Gains will be supported by rebounding levels of motor vehicle manufacturing, a segment that makes up roughly one-quarter of all fastener demand. The fastest growth in fastener sales will be found in the construction market, as construction activity – both residential and non-residential – makes a strong recovery from the declines posted during the 2007-2012 period.

These and other trends are presented in Industrial Fasteners, a recent study from The Freedonia Group, a Clevelandbased industry market research firm.

The original equipment manufac-

turing (OEM) market for industrial fasteners will outpace growth in the maintenance, repair and operations (MRO) market, as US manufacturing output continues to recover from the 2007-2009 recession.

Machinery and aerospace equipment shipments are forecast to expand at improved rates. US fabricated metal product output will rise, and the ongoing trend of ‘reshoring’ in a range of industries will support increases in fastener demand.

Growth in fastener sales in MRO applications will improve from the performance registered during the 2007 to 2012 period, as fixed investment rises and fastener-containing equipment sees

more use with expanding production.

Competition from alternative joining technologies, such as adhesives, clinching and welding, will prevent further gains in a number of applications. Moreover, fasteners are a mature product; while opportunities for value-added technological improvements certainly exist, they tend to be limited in many markets.

Externally threaded standard fasteners will remain the largest single product category, posting the fastest gains, along with application-specific products. MRO Industrial Fasteners is available for US$5,100 from The Freedonia Group Inc. at www.freedoniagroup.com.

Here is how a quarry used an Installed Base

Evaluation service to improve performance

by tracking its mechanical and motor products.

1 Baldor’s Installed Base Evaluation team surveyed products at Premier Silica’s Brady operation quarry. The team provided an accurate count of electrical and power transmission equipment and captured detailed nameplate information, as well as the application and location. All equipment was properly locked and tagged out during the survey. 2 Bills of material and other relevant historical product records had been lost at the plant. Without knowing what products were installed at the facility, plant officials could not put a preventive maintenance or inventory strategy in place. 3 By getting the detailed information on all of the bearings running in the plant, the maintenance team was able to begin a preventive maintenance program using the correct grease and the correct lubrication schedule. 4 The survey of inventoried parts in the warehouse supplied critical information for plant management to determine its inventory strategy moving forward.

W

hen Perry Finco began work as the maintenance manager at Premier Silica’s Brady operation in the spring of 2012, he set a goal of bringing the 35-year-old facility up to 90% efficiency. However, because he and his team had to deal with constant unplanned downtime, they didn’t have the time to get organized.

Their task was made even more difficult because they had no idea what products were installed at the quarry, which included two wet plants, three dry plants, two bagging facilities and two load-out facilities.

Over the years, the Brady operation – located in Texas – had been purchased and sold many times, and bills of material and other relevant historical product records had been lost by the time Premier Silica acquired the operation in April 2012.

“How can you put a preventive maintenance or inventory strategy in place when you don’t know what products you have running in your plant?” says Finco.

“We didn’t even know what products were stocked in our warehouse. Not having this information meant we were operating by the seat of our pants, chasing down parts trying to keep the plant running.”

While Finco knew where he wanted to end up, he understood that without knowing what products he had running in the plant and sitting on the shelf, he had no way to get there. But Finco did have experience with plant surveys at

p12-23 MRO SEPT 2014 Features.indd 14

previous facilities, and when he found an Installed Base Evaluation (IBE) service offered by Baldor, he was very interested.

What the motor manufacturer offered Finco was a team to survey the electrical and mechanical products installed and inventoried at the Brady operation, capturing detailed nameplate information, application information and location details in the facility. This was all the information Finco was missing.

“Because of the fact that we are in such a remote area and a somewhat small project, I was worried about finding a firm to come in and conduct a survey,” explains Finco. “But Baldor was willing to come in and take on the job, and the IBE team fit our needs perfectly.”

After the on-site survey was finished, the IBE team went to work analyzing the data and preparing a report. When the results of the IBE were presented, Finco immediately saw product standardiza-

tion opportunities, a critical step in his strategy to manage inventory better.

“After we had reviewed all the details with our local Dodge field sales engineer, Chris Teague, we made the decision to standardize on Baldor’s Dodge TorqueArm II gearing,” says Finco. “By choosing to use the same size gearbox on multiple pieces of equipment, we can reduce the number of gearboxes we keep in stock in our warehouse. We also believe converting to the new Dodge product will help improve our plant uptime.”

With the survey data uploaded to the Brady operation’s CMMS system, the maintenance team has created its own database, which Finco says is now the framework for a preventive maintenance strategy for both mechanical and motor products across the entire Premier Silica operation.

“We’re using some of the information from the IBE report to write the scope for our new preventive maintenance program,” says Finco. “Now that we know what we have, we are outlining what’s needed for each product, setting up lubrication schedules, as well as other preventive procedures. And because we are now better organized, with all the correct parts on hand, we are prepared to support planned maintenance shutdowns.”

Wrong grease caused constant bearing failures The effort has already had a tremendous impact on preventing the constant bearing failures that had been shutting down production. Finco says by knowing

exactly what kind of bearings were running in the plant, the team was able to upgrade products where necessary and also research the best way to maintain the bearings kept in service.

“What we found out is that we were using the wrong grease,” says Finco. “By conducting the right preventive maintenance with the correct grease and the correct lubrication schedule, bearings are no longer causing shutdowns as they had in the past. And because we know what kind of bearings we have, we are also carrying the right quantity of bearings in the warehouse.”

With strategic plans in place and work well underway, Finco is happy to report that plant performance has improved tremendously since the time the IBE was conducted. He says his team has changed from being reactive to proactive and is getting closer to the plant’s 90% efficiency goal. While there is still work to be done, Finco doesn’t hesitate to recognize that the Baldor IBE was the right tool to help his team move forward.

“This tool helped us refocus our energies to work on all the strategies that will bring this plant back to the reliability levels we know are possible,” says Finco.

“The IBE was just the beginning of our journey. Now we have to stay committed and follow through. However, we could not have begun this work without this survey to get us started.”

Preventing

corrosion in electrical systems The worldwide cost of corrosion is estimated at $2.2 trillion, more than 3% of global GDP. Here are three methods to help control it.

hen specifying electrical products for harsh environments, choosing the right materials to ensure adequate corrosion resistance is crucial. In offshore oil and gas operations, equipment is under constant exposure to seawater and salt spray, which are highly corrosive due to the autocatalytic action of sodium chloride and other dissolved chlorides. Corrosive substances such as hydrogen sulphide and carbon dioxide also occur naturally in oil and gas fields. Other corrosives that affect a wide range of industries include chlorine, bromine, hydrochloric acid and ammonia.

Corrosion can take many forms, and

the correct selection of materials and finishes is the key to preventing each type. Common corrosion control methods include the following.

Selecting materials according to their galvanic properties. Different metals and alloys have different electrode potentials. When two different metals are electrically connected in the presence of an electrolyte, such as seawater, the more active metal will become anodic – losing electrons and increasing its oxidation state in a process known as galvanic corrosion.

The Galvanic Series ranks metals from noble to active, based on the strength of ion bonding at the surface.

A relatively more noble metal, such as

Online Reader Inquiry No. 124

p12-23 MRO SEPT 2014 Features.indd 16

stainless steel, will resist corrosion better than a more active metal, such as cast iron.

Galvanic corrosion can be minimized by selecting metals close together in the Galvanic Series. Alternatively, a more active metal can be used as a sacrificial anode that attracts corrosion in order to protect the more noble metal from attack.

Using protective coatings. Various finishes can be applied to help isolate metallic surfaces from the surrounding corrosive environment. The most familiar example is ordinary paint applied to steel to prevent rust, but there are

many other methods, including baked enamel, epoxy powder coat and PVC coating.

For effective protection, coatings must be applied properly and protected against damage during installation and use. The zinc surface on galvanized steel serves both as a protective coating and, if damaged, a sacrificial anode that will corrode in preference to the exposed steel.

Taking advantage of passivation.

Certain metals form a layer of metal oxide on the surface, a few molecules thick, in a process known as passivation. This occurs naturally, but the process can also be enhanced through chemical passivation treatments or anodization.

Unlike ordinary rust, the passivated layer is tightly bound to the surface, preventing any further penetration of oxygen or corrosive chemicals. The most familiar examples are aluminum and stainless steel, which form passivated layers of aluminum oxide and chrominum oxide, respectively.

If the surface is damaged, the passivated layer normally re-forms quickly. However, adverse conditions can defeat the process. For example, pitting corrosion can occur in aluminum exposed to seawater when chloride ions interfere with passivation. Welded stainless steel can corrode when the carbon content is sufficiently high to form chromium carbides, depleting the chromium available for passivation in the weld zone and enabling a galvanic reaction between areas with differing chromium content.

When properly selected for the intended application, however, passivated materials can provide excellent protection, even in highly corrosive environments.

Choosing non-metallic components. Manufacturers are increasingly offering non-metallic products that are completely impervious to the environments and substances that can corrode metals. Non-metallic materials may be attacked by specific chemicals, however, depending on the composition of the plastics used. The vast majority of applications will never be exposed to these substances.

Prolonged exposure to UV radiation can also degrade plastics, and users in high-UV locations should account for this in their materials specifications.

Not all industries have the same corrosion problems, but all industries do need to take the possibility of corrosion seriously and choose the right materials and products for their particular operations and environment. NACE International-The Corrosion Society estimates the worldwide annual cost of corrosion at US$2.2 trillion, more than 3% of global GDP. Any money that can be saved by preventing corrosion – including the cost of downtime, labour and new equipment to replace failed parts – directly improves profitability.

Soft product,

techniques eliminate vibration in a tissue plant’s pulp dryer, increasing production potential.

I

n my business of providing alignment services, I get to see and work in a lot of harsh environments. In the past, I have written about doing this work in cement plants, which I think are some of the toughest because not only does the cement dust plug up the machines, it’s so abrasive that it wears them out quickly.

Recently, I calibrated a laser system that had been used for a long time in a coke plant at a steel mill and I was reminded of just how harsh and very dirty these facilities are. Another example is a plant that makes a nice soft product – but the environment is anything but – it’s a tissue mill. Can you imagine how much nice, soft tissue is used in North America per day? Per hour? Tons! It’s a large industry.

In one of the tissue plants I am working in currently, you could see some of the tissue or pulp floating in the air. It would get into every corner of the plant – including the machines. The motors would draw it in, adding a layer of insulation they did not need.

Unseen components of this harsh environment are the chemicals used in the process. They attack the motors by adding a coating that degrades them – and all the machines over time.

The main machine in the plant we are working on now is called a Yankee Dryer.

Imagine a large drum as big as a living room that is heated by steam and is spinning. The wet pulp is sprayed onto the drum as it rotates and the steam heat dries the pulp and creates the tissue.

The operators can control the density (the thickness) of the tissue by adjusting

p12-23 MRO SEPT 2014 Features.indd 17

the speed of the dryer. This dryer had a higher than normal vibration at different speeds, so Steve Cameron of Advanced Balancing had made the call that the drive shafts needed to be aligned. My company went in to support the alignment work.

This Yankee Dryer was driven by two separate motors that drive a single gearbox, which in turn drives the dryer. The connecting drive shafts are universal jointed shafts (also known as Cardan shafts).

The shafts are designed to compensate for offset misalignment. With offset, the shaft will run in an angled position (it will be slanted), but the shaft will compensate for the offset (up and down or left to right). However, the two connecting flange faces, one on the motor and the other on the gearbox, have to be parallel with each other in both the vertical and horizontal plane.

Yes, they can be offset with each other, but if there is any angle involved, they will move in the axial plane and vibrate if running at speed.

In essence, the shaft is opening and closing along its length as it rotates.

These shafts have a splined slip assembly to compensate for this movement. It works at very low rpm (even so, it will still wear out), but at higher speeds it will vibrate and eventually damage the motor, shaft and gearbox.

The solution is easy: align the flange faces.

Most good laser systems provide Cardan (universal joint) shaft alignment programs. In this case, we used an Easy

Laser E710 with specially ground, flat, anodized aluminum mounting brackets.

These brackets were attached to the flange faces because that’s what we were aligning – not the outer edge. This meant that we had to remove the shaft, which was worth doing if we wanted to get it right.

The dimensions and distances were input into the system. The heads were rotated after each measurement was taken and then we read the results live on the device’s display.

We made the vertical correction by shimming the moveable machine (in this case, the motor) at either the front or back feet. Then we adjusted horizontally at the front or back feet while watching the movement results live on the device’s screen. We only had to adjust the machines at one foot pairing because we were only correcting angular misalignment – not offset.

The next day, after the shutdown was over and the Yankee Dryer had been restarted, there were some happy faces in the plant. Why? Because we had removed the high vibration level.

This vibration had been restricting the speed of the dryer, so now that it was gone, the big bonus was that production could now speed up the process. This meant it has increased capacity and production output. In other words, the plant has more opportunity for more throughput, if it wants. This is a win-win scenario. The maintenance department increased the

reliability of a machine unit and production added potential capacity.

One note of caution is to be observed when aligning universal jointed shafts.

They are not designed to be perfectly in line. In fact, if they are aligned, they will damage the bearings in the joint. This is because they need a certain amount of misalignment to draw the lubricant through the bearing – the same way a gear coupling does.

This happens more so in shafts that have needle rollers as opposed to the ball bearings used in many industrial applications — but don’t worry, as a small amount of offset will look after this. (If you have the need to have a shaft inline, you should be using a jack shaft.)

There is also another winner – us. By doing the work correctly and working to the correct tolerances, we have achieved very good results that should prove to management that precision driven maintenance techniques should always be used.

or several years the vibration behaviour of the fans in a major industrial facility had been neglected. No predictive maintenance (PdM) program was in place, but eventually a new reliability engineer decided to reduce the vibrations of this equipment by getting the fans analyzed.

After performing several diagnostic tasks, the sources of vibration could easily be detected. Accumulation of dust and dirt on all rotor blades lead to a 1X vibration peak in the velocity spectrum.

The sine waveform and phase analysis confirmed the results. A static unbalance was the reason for the increased vibration.

The balancing procedure was successfully performed on-site during the next shutdown phase of the plant.

Pruftechnik’s VIBXpert II and Omnitrend devices were used for the balancing runs. The static unbalance requires only a one-plane balancing procedure, which was ideal for these fans.

The accelerometers were attached to the non-drive end (NDE) and drive end (DE) bearing in horizontal direction. VIBXpert offers a ‘second plane control feature’, where the second accelerometer controls any negative influence on the NDE bearing during the trim runs. This ensures that the vibration on both bearings will be equally reduced and balanced.

The target quality grade of 6.3 according DIN ISO 1940 was easily reached. The plant went back online a few days later and the customer was extremely satisfied with the result of the service. “In the past six years, I have never seen those fans run so smoothly,” the plant’s operator said.

A

bottling facility was troubled by glass bottles breaking at the end of a series of conveyor lines driven by #60 roller chain, which fed bottles into a labelling unit.

Differing rates of chain wear, stretch and elongation on the multi-stage drives caused variations in speed so that one end of the conveying line would begin running faster than the other. As a result, bottles were slammed against each other, breaking them and halting production.

When this happened, the entire operation had to be shut down to retension the chain drives, which took two hours of maintenance time and stopped all production downstream. The broken bottles had to be cleaned up and dumpsters full of them were sent to a recycling facility.

Additionally, each shift was spending two hours of preventive maintenance time in an attempt to keep the roller chain drives running properly. Regardless, the roller chain had to be entirely replaced every three months.

The facility’s managers solved the problem by converting to synchronous belts. After investigation, they chose Gates Poly Chain GT Carbon belt drive systems. The high power rating of these carbon fibre-reinforced synchronous belts allowed width-for-width replacement with the roller chain drives.

Because a synchronous belt doesn’t stretch over time as does roller chain, the conveying speed remained consistent across all the lines, preventing the bottles from piling up and breaking.

As a result, throughput increased by

Chain Change Converting from roller chain to a belt drive at a bottling facility solved multiple problems.

20%. Fewer bottles breaking reduced the need for and cost of recycling.

Synchronous belts don’t need lubrication, which eliminated the two hours per

shift of preventive maintenance time, freeing maintenance personnel to handle other tasks and eliminating the risk of contamination from the lubricant.

Machinery & Equipment MRO

Also, without metal-to-metal contact, the synchronous belts are less subject to wear. Life expectancy for the synchronous belts is two years, compared with three months for the roller chain.

The annual cost savings resulting from this chain-to-belt conversion was calculated at $330,000 per year, not including the recovery of lost production time and reduced recycling costs. Payback on this one conversion was less than one year.

In sum, the benefits of switching from a chain drive to a belt drive can include the following: • W hen considering investment costs, belts last three times longer than chain, and the sprockets 10 times longer. Total cost of ownership for a belt drive is significantly less than a chain drive.

• No stretch, no lubrication and no metal-to-metal part wear result in a lowmaintenance drive. Hours spent lubricating and retensioning can be refocused on more critical tasks.

• Production is lost every time the drive is shut down. Less maintenance means less downtime.

• The stronger-than-steel carbon fibre tensile cord construction of the belt gives the drive high horsepower-carrying capacity and compactness.

• The belt drive is impervious to washdown, resisting moisture, chemicals, and abrasion.

The importance of electrical

inspections for pump maintenance

Comparing offline testing to newly developed online testing technologies and methods.

tween coils, the insulation of the windings becomes carbonized, basically turning the material into a semiconductor. A semiconductor acts like an insulator until a barrier potential voltage is reached. Then it shorts and behaves like a conductor.

In the case of carbonized winding insulation, a multimeter cannot detect the ground fault because the test voltage of the meter (9-10 V DC) is too low to reach the barrier potential of the carbonized insulation.

In the past we used a hi-pot (high potential) test to find ground shorts: a high voltage potential (2,000 V) is placed across the windings and leakage through the insulation is measured to determine the condition of the insulation. Unfortunately, these testers can cause damage to the windings over time. If there is moisture or dirt present on the winding, then the hi-pot may cause an arc to flash, instantly ruining the windings.

Hi-pot tests are used at the factory to determine the dielectric breakdown

hy should electrical inspections be an integral part of your pump maintenance routine? The answer is simple: performing electrical inspections on pumps and their systems helps to locate faults before they become failures. This allows the maintenance technician to plan ahead by ordering parts or replacement pumps and by scheduling system maintenance well in advance, so that you can avoid costly downtime and emergency repairs.

Moreover, electrical inspections can tell you much about the overall condition of the pumping system. This is especially true for submersible pumps in which the motor and the pump are packaged as a single unit. Most of these pumps are equipped with internal sensors for winding temperature, bearing temperature and the presence of moisture. Over the past five years, vibration sensors have become standard equipment in larger pumps. The information these sensors provide can make the difference between

p12-23 MRO SEPT 2014 Features.indd 20

a simple rebuild or a more expensive stator rewind and rotor replacement.

In short, regular electrical inspections can help reduce each pump’s total cost of ownership and make significant contributions to system reliability and uptime.

Offline testing During a motor inspection there are several tests that are performed on the stator windings. Using a multimeter, we can test the resistance of the coils and compare them to each other.

For single-phase motors, the resistance readings can be compared to an ohms chart provided by the manufacturer. In three-phase motors, the resistance (ohms) on each phase should be within 2%.

Shorts to ground can only be found with a multimeter if there is a direct short. Other conditions, like moisture, dirt or carbonization, may not be detectable.

When there is electrical arcing between the windings and ground, or be-

voltage of new windings. A hi-pot test is also required for explosion-proof certification. Today, we use a ‘Megger’ (a registered trademark of the Megger Corporation) to test for shorts to ground. Megger tests work by sending a low amperage (0.001 A) pulse of DC voltage between the coil leads and the stator ground at two times the motor’s operating voltage (250-1,000 V).

The Megger displays the results in megaohms. The readings from the Megger can determine whether there is a direct short to ground or an insulation fault in the windings – such as from moisture or dirt. In the case of moisture or dirt, the stator can be washed, dried and re-dipped in varnish, saving the owner an expensive rewind.

For coil-to-coil and turn-to-turn shorts, multimeters and Meggers can only detect a major short. For minor shorts, you need a coil and winding tester. When there is a small turn-to-turn fault, there will typically be only a tiny change to the DC resistance. With larger motors

this change can be too small to detect with an ordinary multimeter.

To find the short we must look at the difference between the AC resistance (inductance) and the DC resistance.

While the DC resistance may change only slightly due to a minor short, the AC resistance will vary greatly with frequency. By comparing the three windings while testing over a range of frequencies, minor shorts can be easily detected.

There are two types of coil and winding testers. Both types input a low-voltage AC signal and read the output. A surge tester, the most common style of coil tester, has a screen that displays the waveform as the tester steps through the frequencies. Other types calculate the differential internally and display the results on a screen.

Online testing The most exciting new development in the world of pump electrical maintenance is the development of online testing. This new breed of instruments can be attached to a pumping system to monitor the pump and motor while they are running.

Using online testing, we can analyze the temperature, vibration, flow, pressure, power and electrical waveforms.

On the motor side, we can detect problems with the incoming power and bearings, as well as stator shorts and dirty or wet windings. On the pump side, we can measure the intake pressure, discharge pressure, fluid temperature, flow rate, bearing condition and vibration.

Another feature of online testing is the ability to collect measurements over a period of time. We call this data logging. The majority of pump system problems happen when an operator is not present, the so-called ‘ghost’ failures that occur in the late hours of the night.

Data logging can monitor multiple channels of information for long periods of time to capture these events as they happen. Examining data logger records collected over extended periods can also reveal trends that point to a gradual deterioration of pump or motor conditions before they become critical.

With a data logger, we can also see the operating parameters of the pump system and evaluate the exact duty point and duty cycles of the system. By comparing this information with the manufacturer’s pump curves, we can determine with high accuracy where the pump is operating on the curve, measure the system curve and also determine where the motor is running on the power curve. This information allows you to see the effects of pump wear, pipe restrictions and suction issues.

You can also accurately calculate the pump system efficiency, which allows the engineer to offer solutions that can improve efficiency, reduce wear and decrease downtime.

A great example of this is the KSB SES system, an advanced data collection tool capable of monitoring complete pumping systems. By using electrical inspections during pump maintenance, you can diagnose pump system issues, offer pump owners accurate data on their pump system and find failures before they happen. The result? Better pump performance, better system availability and lower total cost of ownership.

Is the way you’re doing pump startups wrong?

BY ROSS MACKAY

D

uring a recent in-house training program with a company in Trinidad, our discussions were directed to the problems of starting up a pump, and I was reminded of an experience I had with a plant engineer in an old chemical process facility some years ago in Europe.

For reasons that will become obvious, I will not identify the plant or even a more specific location.

We were walking through his facility to inspect one of his ‘bad actors’ (a pump that was giving him frequent and regular difficulties). As we passed another pumping unit, he paused briefly and pressed the green button to start up the driving motor, and immediately resumed walking.

Knowing that automated controls were unlikely to be connected to this particular installation, I stopped and asked him if he was going to open a valve or two. His response stunned me. He said, “Oh, we’ll just let it run for a little while to let it warm up, then we’ll put it online.”

It turned out his “little while” could be anything up to five or even 10 minutes.

When I asked if this was a regular practice, he assured me that it was standard with all pump startups, and had been practiced for all the years he had been employed in that facility (over 10 years).

We then reviewed some of the major problems of running a pump in the shutoff condition – challenges such as high temperature build-up and excessive radial loading, both of which result in reduced pump reliability. Since a high incidence of seal and bearing failures was a normal occurrence in that plant, we then agreed that their traditional startup process should be changed.

In general terms, there are only three things we need to do to start a pump.

First, we prime the pump. To do this with a flooded suction, the suction valves are opened and the liquid is allowed to flow into the pump. It may also be necessary to open an air-release valve at the highest point in the pump casing to ensure that all the air/vapour is bled from the pump as it fills with the pumpage.

When operating on a suction lift, the same effects must be achieved manually, while, if a self-priming pump is used, this step is unnecessary.

The next step is to start the pump and open the discharge valve.

Which comes first, the pump or the valve? This decision is based on two factors; the pressure in the system and the driver horsepower. With most process pumps, the driver is usually sized to accommodate the run-out condition, which allows the pump to be started against an open valve.

However, if the pressure in the system beyond the discharge valve needs to be maintained at an operating pressure, then the pump needs to be started

against a closed valve, with the valve being slowly opened as the pump comes up to speed.

The major exception to this is with pumps with a high specific speed impeller, such as the axial flow design found in vertical propeller pumps. With

Running a pump in the shutoff condition can lead to high temperature build-up and excessive radial loading, both of which result in reduced pump reliability.

this type of impeller, the highest power draw is at the shutoff condition and the driving motor horsepower does not usually cover the demand at that point. In view of this, the pump must be started up with an open discharge valve, thus allowing the pressure resistance in the

system to build gradually up to the required operating head.

pecial considerations need to be applied with equipment used for drinking water applications.

These applications are influenced by the NSF/ANSI Standard 61: Drinking Water System Components – Health Effects, which was first published in 1988 to establish minimum requirements for the control of potential adverse human health effects from products that contact drinking water (potable water).

Availability

NSF/ANSI 61 includes criteria for testing and evaluating products to ensure they do not leach contaminants into water, thus creating a health concern or hazard.

Developed by a team of scientists, industry experts and key industry stakeholders, NSF/ANSI 61 sets health effects criteria for many drinking water system components, including sealing materials such as rubber sheet.

products are required to comply with NSF/ANSI 61 by most governmental agencies that regulate drinking water supplies. As a result, NSF/ANSI 61-certified gasket materials are the preferred materials for drinking water and sanitary service applications.

NSF/ANSI 61 is quite comprehensive.

The standard establishes minimum criteria for impurities and contaminants that may be released indirectly into drinking water from products, components and materials, including the following: • Protective barrier materials (cements, paints, coatings) • Joining and sealing materials (gaskets, adhesives, lubricants) • Mechanical devices (water meters, valves, filters) • Pipes and related products (pipe, hose, fittings) • Plumbing devices (faucets, drinking fountains) • Process media (filter media, ion exchange resins) • Non-metallic potable water materials.

While the fluid sealing industry is affected by the requirements of NSF/ANSI 61, the industry has been somewhat slow to react to the standard. However, this is now changing, with wider adoption of the standard serving to drive an increased availability of gaskets and sealing materials that are NSF/ANSI 61 compliant.

NSF/ANSI 61 requires that only gaskets and seals approved by NSF certification can be used in facilities and in applications where the standard has been adopted as a requirement. Certification of gaskets and seals provides an assurance that the products have passed all the required physical property tests and that they are approved for use in situations where compliance to NSF/ANSI 61 is a requirement.

At the time of writing, there are now about six North American manufacturers of gasket and sealing materials offering a product that is certified to the requirements of NSF/ANSI 61.

The latest gasket material certified to NSF/ANSI 61 to come onto the market is the NA1002SAN sheet manufactured by Teadit North America, a manufacturer of gasket sheet material. NA1002SAN sheet is especially designed for sanitary service applications and it combines excellent physical properties and performance characteristics (see table) at a lower cost than many competitive offerings.

The advent and adoption of NSF/ ANSI 61 means that traditional materials used in water sealing applications, such as gaskets and seals fashioned from red rubber, will give way to newer-generation materials that are NSF/ANSI 61 compliant. It is therefore highly recommended that when purchasing gaskets for potable water applications that you source product from distributors and gasket cutters who can supply product that complies with NSF/ANSI 61. MRO Bill Searle is a technical sales specialist with Canada Rubber Group Inc. (CRGI), Bowmanville, ON, a provider of fluid sealing products and services. For more information on NSF/ANSI 61 compliant gaskets and seals, contact him at bsearle@ canadarubbergroup.com.

The importance of

training

Structured employee orientation and training processes are a way to give new employees a fair chance to show they are willing and able to work.

BY PETER PHILLIPS

This issue’s column continues a look at an ongoing project aimed at improving maintenance operations at an Ontario food plant. his plant needs to develop support systems for every position and activity that its personnel are responsible to perform. We have implemented some intermediate corrective actions to improve communications between maintenance and production, and at the shift handover meetings to improve communication with the day shift management.

The plant realizes that there are many areas that need attention. The plant is experiencing tremendous growth, with new products being developed and millions of dollars being invested in new equipment. There are days when five to 10 new employees are being hired.

We identified in our last visit to the plant that the new employee training process has little structure and employees do not receive quality instruction or and training. We will now address this issue and focus on new employee orientation and training. A process to monitor the progress will be implemented and

T

ongoing support will be provided as the new hires progress through on-the-job training.

Properly trained people result in fewer production errors, a higher retention of employees, and a faster transition into them being productive and happy employees.

We have noticed a common theme in industry across Canada. It is getting increasingly difficult to find and hire people with good work ethics. In another example, we recently were working at a food processing plant in Newfoundland. For those of you who are not familiar with the current Newfoundland economy, you may be surprised to learn that the province is booming. The oil, mining and electricalgeneration projects – along with various support companies – are driving a full economic expansion. Housing costs in many cases have doubled and anyone who wants to work can find employment.

A few months ago, I was staying in a town about two hours from St. John’s and it had a brand-new coffee shop sitting closed because, I was told, there were not enough unemployed people in the local area to hire and open it.

The management team at the St. John’s food plant explained to me they were having problems finding quality people to fill vacant positions in production and maintenance. They, like those in every other industry, want employees who want to come to work every day, want to work when they arrive, and who want to have an interest in doing a job in an efficient and effective way.

Unfortunately in Canada, many of our younger generation feel they are entitled to a job that pays well and requires little effort from them, regardless of their education or experience. Every person – young, middle-aged and older – must understand that companies need reliable, hard-working, dedicated employees so the company can make money and therefore pay them a salary. Companies across North America are struggling with this issue, especially in areas of high economic growth and low unemployment rates.

There are no easy answers or quick fixes to correct this issue.

However, we believe that structured employee orientation and training processes are a way to give new employees a fair chance to show they are willing and

able to work. It also gives the employer a way to measure the new employee’s skills, knowledge and attitude. It will also help the employer to determine if the employees will be offered permanent employment after their probation period.

Back at the Ontario plant, we will indeed start with new employee processes and support systems. As one experienced employee explained, poorly trained production employees cause problems all the way down the production line. We have seen this since our first visit, as the company struggles daily with production mistakes that cause startup delays, waste and rework.

It’s not because the people are incompetent, but because they do not know their roles and responsibilities. They have not been given meaningful and effective training from the beginning. As I look back at the employee questionnaire we did back in January with the plant’s production crew leaders, improvement in the training of new people scored very high in importance.

We will visit this plant again next month and will thoroughly examine its orientation and training programs. I plan to spend at least a full day acting as a new employee and experiencing the process first hand. I will be able to communicate with other new employees about how they feel on the first day at work. Then I’ll be able to do a full analysis and determine what changes and improvements need to be developed to properly introduce people to the company and the training process. This done, we can help them to develop an effective company orientation and a structured on-the-job training package for every production position and work activity.

We also will recommend that all recent new employees go through the new training process. We realize this development may take several months but we also know the company is committed to these improvements.

The goal here is to stop the daily reoccurrence of line problems caused by poorly trained people and to effectively address these problems at the source.

Once again, we will stick to our fundamental belief that we need to set up people to succeed every day. Doing so, we will have happier and more productive employees.

When we started this project, the plant manager estimated it would take two years with us on-site for one week a month to turn the plant around. We agreed to this and we are soon to have our seventh visit. Improvements are being noticed and people are totally on board with us, so we know success will be the result.

Schaeffler develops bearing supports for water power applications that can be directly installed in water, using a special steel that is resistant to corrosion for the rolling bearing rings. The rolling elements are made of ceramic, while the cages are manufactured from water-resistant plastics. There is no need to use oil and grease because the rolling bearings are lubricated by water. Reliability and low maintenance are important requirements since, once the plants are installed under the surface of the water, access to them is limited. Water power will make a significant contribution to supplying renewable energy in the future, including tidal stream and wave power sources, in which turbines are installed under water to use the energy from currents and tides. The company is involved in numerous projects of this type as a development partner.

Spherical washers optimize bolt mounting of machinery

▼

SKF Spherical Washers optimize bolt mounting of machinery and bolted equipment by integrating unique design features, promoting ideal performance in industrial, marine, and all other heavy-duty bolted joint applications.

The all-spherical two-piece washer automatically adjusts under compression to compensate for up to four degrees of angular deviations. This creates an exact parallel plane between the inner face of the bolt head and inner face of the nut to distribute the load evenly over the entire inner contact surface areas. Any need for on-site machining (spot facing) to achieve parallelism is eliminated. The washers ultimately serve to reduce the likelihood of bolt relaxation by distributing bolt tension evenly, retaining proper bolt tension by preventing bolt bending, and keeping bolts straight as intended. The extended length of the spherical washer allows for the use of longer bolts, resulting in additional bolt clamping length and elongation in the bolt.

A linear speed control option for Model RG rolling ring linear drives has been introduced by Amacoil/Uhing. Normally, the drive moves on a driven shaft with linear speed being adjustable via a pitch control lever located on the drive unit. The option lets users fix a specific linear travel speed in one or both directions of travel. The fixed travel speed is achieved using set screws that Amacoil inserts into the drive housing. No adjustments to motor speed or controls are necessary. Based on application needs, the company will work with customers to determine custom settings for the set screw speed control option. The option is inexpensive and is easily retrofitted to existing Uhing linear drive set-ups.

EDT has added Type E bearings to its Solution line of severe-service bearings.

These durable, cost-saving bearings have high load capacity and the same dimensional footprint as industry-standard Type E tapered roller bearings. Non-corrosive and completely greaseless, they are constructed with a 304 stainless housing, a Poly-Sphere plane bearing that is made from a high performance polymer, plus a 316 stainless locking sleeve. Plane bearings work without rolling elements, so grease is unnecessary and seals are eliminated, reducing maintenance.

Plane bearing design also makes it possible to offer completely split inserts in addition to split housings. The bearings are available in one-piece or split styles of pillow blocks, four bolts and piloted housings for shaft sizes from 1-3/16 in. to 5 in. Split units are drop-in replacements for RPB, RFB and RFP spherical roller bearings with the added options of split bearings and split sleeves.

Gearbox radial shaft seal material is for use with synthetic oils

Simrit’s 75 FKM 260466 fluoroelastomer material, a wear-resistant FKM, was developed for use in radial shaft seals that interact with aggressive oils in various industrial gearbox sealing applications. FKM material blends are commonly used in applications containing synthetic oils because of their high-temperature and chemical resistance. However, when blends encounter synthetic oils, they can demonstrate wear and material degradation, which reduces the service life of the entire application. Simrit’s material, in contrast, provides a high level of wear resistance when in contact with synthetic oils and good resistance properties over the service life of radial shaft seals across many temperature and load ranges. It has the potential to significantly extend the service life and decrease the downtime of industrial gear applications. In addition, the material can be processed in existing injection-

vent damaging shock and rebound. They also act as sound dampers, and can be used as levelling feet. The parabolic shape generates progressive resilience characteristics, and impact and shock effects are absorbed more gently. The product line includes inch and metric sizes, tapped and stud types, and cylindrical and conical styles to accommodate a wide range of applications.

Education opportunities abundant at PTDA Canadian Conference Quebec City – More than 200 people gathered June 5-7, 2014, at the historic Fairmont Le Château Frontenac, in Québec City, QC, for PTDA’s 13th annual Canadian Conference. Networking between channel partners and peers was a top priority at the event.

The Canadian Conference kicked off with an Industry Showcase and Welcome Reception, which featured tabletop displays by 28 manufacturer members. A highlight of the event was a reception and dinner at the Parliament Building, home of the Assemblée nationale du Québec.

Canadian Conference co-chairs Gerry Prezeau, Rotator Products Ltd., and Bruno Mylchreest, Timken Canada LP, alternated as the conference’s emcees. PTDA president Ken Miko, BDI, spoke on PTDA’s strategic plan and PTDA Foundation president Barb Ross, Garlock Sealing Technologies, addressed recent successes of the Industrial Careers Pathway program.

The conference program also included several other speakers: • A ndrew Bell, reporter and news anchor on Business News Network, interspersed his rather bleak outlook for manufacturing in Canada with clips of bloopers from various news media outlets.

• Nigel Southway, president of Nexus Consulting and chair of the Toronto chapter of the Society of Manufacturing Engineers (SME), informed

attendees about the need for and the goals of SME’s ‘Take Back Manufacturing’ initiative.

• A briefing on the aerospace market was presented by Dale Gordon, director of supplier quality assurance for Aerojet Rocketdyne. Speaking on behalf of the International Aerospace Quality Group, Gordon discussed the organization’s efforts in product and supply chain improvements.

• In response to recommendations for industry-relevant content, the Canadian Conference called up a panel made up of a quartet of industry executives to discuss how technology is affecting distributor/manufacturer relationships.

• Attendees were entertained, motivated and engaged by Stephan Maighan’s closing keynote. Interspersing his six lessons for achieving excellence with activities involving combination locks and dancing, Maighan used his own experience to demonstrate how a positive attitude can produce a positive result.

The PTDA is the global association for the industrial power transmission/ motion control (PT/MC) distribution channel. Headquartered in Chicago, it represents distribution firms that generate more than $16 billion in sales and span over 3,400 locations. PTDA members also include manufacturers that supply the PT/MC industry MRO
