Maintenance goes supersonic

MAKING maintenance valuable We read and hear the "R" word just about everywhere we turn lately, but what impact might a recession — if we're in one or if we slide into one — have on the maintenance sector?

Well, in any economic slowdown engineers might evaluate equipment purchases more closely, try to stretch equipment use with duct tape and baling wire, and hope to get by a little longer with what they already own. But research shows that industrial personnel are often more productive and more efficient — that means more profitable — when working with a newer technology and equipment that doesn't break down. Plus, if you're an engineer who borrows to buy, you might take a closer look at current interest rates. Recession or not this might be the perfect time to replace or upgrade.

Industry does not stop working, and this is more true now than it was 10 or even five years ago. Unlike many other industries, maintenance is recession resistant because the work is always out there. Equipment faults don't go away, they continue to cost money and deteriorate. Plus many industry managers, and public agencies have grasped the concept of preventive maintenance, and they understand that pennies spent now could be a pound saved later.

So your company is still going to need their equipment, repaired, and upgraded. Recession or not you can still use your expertise and your service to make an impact on your company’s productivity.

Performance, Precision, Partnership

Reliability and maintenance management expert, president of Idcon, Christer Idhammer, explains how manufacturing reliability enables cost effective process improvements

Lean on:

MANUFACTURING RELIABILITY Lean manufacturing, including lean maintenance, is a well known concept in the United States and in Europe – one which has increased in popularity in the past five years. Simply put, the lean concept should result in products being manufactured on time and with less resources. It doesn’t always mean doing more, as that can result in waste, but it does mean that items that have been sold should be produced when they need to be delivered.

To become lean it is imperative to prevent maintenance needs and to perform the remaining maintenance more effectively. If the previous concepts are implemented, then the production reliability will increase and thus the production costs, including maintenance costs and costs for storage, will decrease.

In effect, all losses in the manufacturing and delivery of raw material and delivery to the customer must be eliminated. Focussing on the manufacturing phase, the biggest losses in maintenance, and therefore the biggest improvement opportunities, include: Manufacturing reliability loss in quality stop times loss in speed

Partnership between operations – maintenance – engineering reliability and maintenance related design operator based maintenance Eliminating the root cause of the problem choose problem to eliminate eliminate problems educate and teach

Storage reduce store value while preserving service level to maintenance Integrating increased knowledge and skills educate and train to enable multi craft or multi skills implement flexible work systems

IMAGE 1. It isn’t always obvious where improvements in the manufacturing chain will be the most cost effective. Flow of a product is the result of Capacity x Reliability. At first glance you could believe that C is the bottleneck in the production chain since capacity there is 316 pieces per hour compared to the higher capacity in A (356) and B (333). If you calculate the flow you will find that the bottleneck is actually at manufacturing stage B. This is compensated and hidden by increased storage of work in progress (WIP) so it can sometimes seem that throughput is not a problem. WIP is a big hidden cost for a lot of companies. With low reliability, throughput of product in the manufacturing chain takes longer and the costs are increased for WIP.

Your Inefficient Motors are Wasting Money Are your motors overrated, are they running at their most efficient, perhaps their load is adversely affecting their operation?

Unless you test your motors you will not know the answers. With Baker condition monitoring equipment, data from on and off-line motors can be quickly collected and analysed and action taken to improve efficiency and avoid critical failure.

The Baker Explorer on-line tester offers a comprehensive view of motor health whilst the motor is running. It will also identify rotor bar, power quality, bearing and other mechanical issues.

The AWA Winding Analyser offers an automatic testing programme enabling less skilled staff to complete tests successfully, combining surge, polarization index, DC Hipot, megohm and winding resistance tests in one field-portable unit

IMAGE 2. By raising the reliability in step C to 83% the increased throughput is 260 per hour. WIP is reduced since the manufacturing steps are now balanced. Other solutions include increasing capacity by investing in a parallel machine for C. However, this would lead to unnecessarily high capacity in step C. Moreover the cost of buying more capacity is about ten times higher than investing in measures that will increase reliability.

Over manufacturing making more than has been sold manufacturing too early Over maintenance perform too much and incorrect preventive maintenance perform preventive maintenance before it is needed incorrectly prioritise corrective maintenance Use new technology less maintenance required better maintainability smart tools and methods All these areas need to be examined in detail, kicking off with the fundamental concepts behind manufacturing reliability.

The sub-target behind lean manufacturing is to reduce WIP and speed up throughput in the manufacturing chain.

This can be achieved by addressing reliability, which includes quality, time and speed. Lean maintenance therefore has a crucial role in improving the reliability of manufacturing equipment and with the manufacturing process ever more dependent on automation, good maintenance is increasingly important.

Availability or reliability?

Many organisations use availability as a key measurement for manufacturing efficiency, however availability encompasses only the percentage of planned time, or available time, that a production process produces. Availability excludes the quality of that which is produced. In fact, producing something that isn’t up to standard is often more expensive than producing nothing at all.

Conversely, to slow down a process because, for example, a part of the production process can’t operate at full speed, is also expensive.

For this reason, it is important to focus initiatives on all aspects of manufacturing reliability: quality, time and speed.

Manufacturing reliability can be measured in various ways and can be expressed simply as: how much is manufactured at the right quality divided by how much could have been manufactured at the right quality. Or, % Quality x % Time x % Speed. Overall nothing should be manufactured before it has been sold and is to be delivered.

In many heavy process industries it is still common practice to produce as much as possible. Lean thinking on the other hand teaches that nothing should be produced until it needs to be delivered because it has been sold.

Computer companies present a good example. When you order a computer from Dell, for example, the order is sent to production planning, which assembles the computer ready to deliver within a few days. Instead of having all types of computers in storage, the whole company’s economy including cash flow, liquidity, costs for materials and material storage and capital costs are affected.

Automation equals maintenance Producing things just in time via a lean production process is impossible if production reliability requirements are very high. With a raised automation level the company becomes more dependant on reliable equipment - in other words maintenance.

Reliable production equipment is the most important result of the maintenance operation and it can be seen as the maintenance department’s route to income generation. To become lean it is important to identify where the greatest savings could come from. What is the worth of reducing the difference between how good you are and how good you could be? In a market situation where you can sell everything you can produce, the equation is simple.

In certain industries the sale price of what you are selling can fluctuate

drastically. In that case calculations should be based on the average sales price and variable cost over, for example, five years.

Average sales price five years - £510/unit Average variable cost five years - £340/unit Benefit per produced, sold and delivered unit - £170/unit The value of producing and delivering a sold unit is £170. If you currently produce and deliver 25,000 units per year and your production reliability is 88% but it is possible to reach 94% then the value of increasing production reliability is 6%.

1500 units x 170 = 255,000 £ per year.

The next question is whether it is possible to reach even better results by focusing on lowering maintenance costs.

Could it be more beneficial to lower maintenance costs if manufacturing reliability is maintained at 88%?

The answer seems obvious, but it isn’t unusual that economists are so focused on lowering visible costs that they don’t see the invisible opportunities that are concealed in increased production or faster product throughput.

A concept worth repeating many times, is that by increasing manufacturing reliability, manufacturing costs, including maintenance costs will decrease.

If you can’t sell the increased volume that you can reach with the higher manufacturing reliability, then the savings most often lie in more reliable and faster delivery of goods sold, less energy expenditure, better safety and less overtime. www.idhammarsystems.com Reader Reply Number: 300

A thrilling performance Equipment from Ashtead Technology Rentals is set to appear in a television adaptation Ashtead's Olympus Iplex FX videoscope is to feature in TV thriller, Above Suspicion

of Lynda La Plante’s latest thriller.

The production company hired an Olympus Iplex FX videoscope to portray authentic crime investigation scenes when filming Above Suspicion, which will air in November.

The videoscope is designed for industrial inspection, providing portable and intelligent remote imaging with an internal battery providing two and a half hours operating time. Head of research at La Plante

Productions, Cass Sutherland, said: “The police use remote visual inspection equipment to investigate crime scenes without interfering with potential evidence so we needed an instrument to be used by the characters on screen.

“Ashtead not only helped us decide which videoscope would be most appropriate, they also delivered the device quickly and efficiently.” www.ashtead-technology.com Reader Reply Number: 302

WATER GOOD SOLUTION Predictive maintenance is proving increasingly popular in the water industry where it helps improve asset performance. One solution is the Artesis motor condition monitor (MCM), said to provide traditional condition monitoring benefits at a fraction of the complication and cost.

Using a model-based approach, Artesis MCM provides complete monitoring and diagnostic capabilities for most electric motor driven equipment. Installation costs are said to be low, with no need to access the driven equipment for sensor installation. Once installed, the system trains itself to recognise normal performance, following which it continuously monitors the equipment for possible faults. When a fault is detected, the system

provides a diagnosis and indicates severity so the user decide on the most appropriate intervention.

Artesis MCM is particularly good for inaccessible equipment like submersible and borehole pumps and has already been installed by one company providing water services to a major city.

In the first year of operation, the system reduced maintenance costs by around 10 per cent by avoiding breakdowns and reducing spare parts. After three years, no unpredicted breakdowns had occurred, leading to the inclusion of Artesis MCM units as a standard element in all new build specifications. www.artesis.com Reader Reply Number: 303

Service standards flying high Aircraft equipment manufacturer, Messier Dowty, is to install five new ovens fitted with ABB instrumentation, including temperature controllers and videographic data recorders.

The order expands ABB's 50-year service and support contract with the manufacturer of aircraft landing gear, which currently sees ABB take responsibility for around 200 temperature instruments across the site.

Instruments in the new ovens will be used to measure the performance of processes such as heat treatment and surface finishing to ensure they remain within strict tolerances.

ABB’s service engineer for Messier Dowty, Bob Clow, said: “Inaccurate temperature measurement during the heat treatment process could result in components not being properly treated, potentially leading to failure during operation.

Predictive maintenance ensures optimum instrument performance from routine checks through to installation, commissioning and equipment upgrades.”

As part of its service contracts, ABB also calibrates and certifies its temperature equipment to the AMS2750 standard covering thermal processing equipment used for heat treatment processes. www.abb.com Reader Reply Number: 304 Predictive maintenance keeps ABB instruments at optimum performance throughout their service life

FLOW METER CUTS ENERGY COSTS Suitable for use in gas, steam and liquid applications, Deltaflow flow meters from Flowline are said to offer precise and economical performance to achieve energy savings. These differential pressure probes measure flow in pipes and conduits and can be used in a variety of industries.

In power plants, for example, Deltaflow can meter all gaseous media including feed air, preheated air, recycled stack gas and flue gas. It can also meter media with high particulate content, less than 200g/m2, live steam, low/mediumpressure steam and feed water, all tested per PED97/23/EG with CE certification.

Exact measurement of combustion exhausts means efficiency levels can be adjusted for optimum performance and because pressure loss levels are low,

Deltaflow probes measure flow in gas, steam and liquid applications

users can specify pumps, blowers and compressors with narrow profiles, resulting in further energy savings.

The meters can also be used in chemical and petrochemical industries for metering products, exhaust or flue gasses, inert or aggressive media as well as for measuring biogases and sewage gasses in the water and wastewater treatment industries.

The Deltaflow series can be used on pipe diameters from three to 15,000mm and pressure ranges span zero to100 bar, up to zero to 690 bar. Temperature range is from -200 to 1240ยบC and the unit is available with a weather-proof casing for outdoor applications. www.flowline.co.uk Reader Reply Number: 305 Highlighting kerbs and steps reduces accidents such as slips and trips

Transforming oil management One of five HSL workstations supplied to EDF featuring reservoir tanks for oil extraction during transformer maintenance

Surface coatings and fabrication specialist, Hi-Tec Spray (HSL) has provided a spray booth, test booth and a full transformer oil management system to EDF Energy Networks. The equipment, supplied in partnership with Unipart, will be used by EDF as part of its ongoing substation maintenance programme.

Within the oil management system five, temporary, reservoir tanks with integral workbench tops enable the extraction of oil from the transformers to facilitate repair work. Each tank houses various level switches to assist controlled removal.

Each station also has a Graco air operated Husky 1040 double diaphragm pump that can transfer oil to or from any of the 500l stainless steel reservoir tanks. To safeguard against leaks or major spillage all are mounted on a fail-safe bund.

For straightforward oil changes, two 800l intermediate bulk containers, also with Graco 1040 pumps are used to vacate all oil from the transformer. As no repair work is necessary, these skid modules have no need for a benchtop facility, using a forklift truck instead to enable oil changeover in a more convenient environment.

Two custom built booths complete the project, including a spray booth equipped with an airless manual spray unit and a smaller test room enclosure.

Slips, trips and falls can be reduced using Watco high visibility paint to highlight hazards such as kerbs or steps. Suitable for use on concrete, stone, brick, masonry, asphalt and similar porous surfaces, the paint contains fluorescent pigments to improve visibility. It can be applied by brush or roller to damp surfaces and only one coat is normally required. The paint is also ideal for line marking and walkways and offers resistance to UV and weathering.

BRIGHT IDEAS ON SAFETY

Forces attracted to fuel savings Magnetic fuel conditioning units supplied by Magnatech Fuel Conditioning have been installed across five MOD bases in England. Magnatech installed the units on all types of gas and oil burners from a single domestic to a large CHP unit or main boiler room.

Previous MOD technology trials

indicated that the units achieve payback within a year, with the installed units now saving more than their purchase price every year with no maintenance or running costs. This figure is rising as fuel prices soar.

To realise these savings, the Magnatech units are fixed to the

outside of the gas train or oil line, while the boiler remains in full operation. No pipes are cut and there are no fees for third party assessment. According to Magnatech, fuel consumption is reduced by as much as 10 per cent with magnets losing just one per cent of their power in 100 years.

ABB's ABB's gas gas detection detection system system replaces replaces aa 30-year 30-year old old ancestor ancestor product product at at Snowdonia's Snowdonia's underground underground substation substation

When the Dinorwig hydroelectric substation in Snowdonia needed to replace its 30-year old gas detection system, engineers chose an ABB AK100 gas analyser to do the job. Interestingly, the technology at the heart of the new katharometer is exactly the same as its predecessor because the essential approach has not been bettered.

Designed to check for leaks of sulphur hexafluoride (SF6) from high-voltage contactors, the katharometer detects the presence of a gas by comparing the thermal conductivity of a sample with that of a reference gas – in this case air. Any leaks could lead to both suffocation and arcing in the switchgear. The £17k Dinorwig system therefore monitors six sample points using a common katharometer and a stream switching unit comprising a timer and valves.

ABB product systems manager, Andy Jones, said: “The AK100 uses established technology. The peripherals may have changed, but the basic technology is so robust that no-one has ever come up with a better alternative.” www.abb.com Reader Reply Number: 309

Teseo has extended its modular aluminium pipeline system with a new DT drilling jig, which allows use of a 19mm drill bit, the correct bore size for an outlet plate that carries 3/4inch treaded connectors. In addition a new outlet plate with 11/4 inch thread is now available for use with the HBS 80 and 110 pipeline profiles.

As ever, there is no need to turn off the compressor to expand the system using the new equipment. To open a new air point on an established system under full pressure, users fix the outlet

plate on the pipe run, screw a ball valve to the outlet plate, screw the Teseo drilling jig to the ball valve, open the ball valve to allow the drill bit through and drill the aluminium extrusion piping. Swarf is collected in the drilling jig.

Remove the drill bit and shut the ball valve, remove the drilling jig, couple up the additional airline to the ball valve and the new air point is installed.

Users experience no loss of pressure, no down time for the rest of the plant and an instant delivery for a new workstation.

VALUE DRIVEN MAINTENANCE Founder of maintenance consultancy, Mainnovation, Mark Haarman, asks what a valuable maintenance organisation really looks like

MAKING

maintenance valuable According to the value driven maintenance (VDM) philosophy, maintenance creates value for a company in four ways: reducing costs (cost control), improving equipment availability (asset utilisation), reducing the spare parts in stock (resource allocation) and improving compliance with regulations covering safety, health and environment (SHE). Using net present value (NPV)-formulas it is possible to calculate the value potential for every value driver. After that the maintenance organisation has to focus on the value driver with the highest value potential.

The question is: what does a maintenance organisation that creates maximum value for a company look like?

Is it centralised or are there decentralised maintenance organisations close to, or even under, production? Is all the work done in-house or is it outsourced to contractors? Which work processes are being applied and how are the EAM and CMMS being used?

To answer those questions we first have to understand how a maintenance organisation operates using the VDM competence model.

This competence model shows that there are two improvement loops - one around cost control and one around asset utilisation. A company focussed primarily on cost control will manage its improvement loop by implementing a maintenance budget, preferably per critical installation.

Within the competence of reliability engineering, the preventive maintenance program has to comply with financial targets.

After that competence planning and preparation addresses preventive and corrective maintenance jobs. Once these are completed, the costs have to be registered for analysis purposes, to appreciate the cost drivers and thus initiate corrective measures to comply with the financial targets. This closes the Demming circle: plan, do, check, act.

A maintenance organisation that focuses on uptime however, has to deal with a completely different Demming circle. Here the target is the service level agreement with production, in which performance targets regarding equipment availability and reliability are determined.

In this case it is also important to embed these agreements in the preventive maintenance program, after which the work orders will be prepared, planned and executed. For this improvement loop it is important that production losses caused by preventive or corrective maintenance are registered to be analysed and to locate the performance killers.

The VDM model demonstrates the importance of the competence reliability engineering, because it is the most important link between improving cost control and asset management.

Also, reliability engineering translates the demands from safety health and environment into the preventive maintenance program and sets boundaries for the four maintenance resources: technicians, spare parts, contractors and technical knowledge.

With this competence model we can determine the most valuable maintenance organisation. VDM provides best practices of leading maintenance organisations for each competence. RCM for example is known for best practice in the area of reliability engineering and TPM is mostly used to support asset utilisation improvement.

For cost control however, a method such as asset based budgeting is best suited and RBI is mostly used as best practice in the area of SHE management.

Re-using proven best practices accelerates the change process and increases the credibility of changes as they have already worked for other companies.

Can we conclude that there is one standard for the most valuable maintenance organisation? Yes and no.

Yes, with VDM there is a standard approach for designing and building the most valuable maintenance organisation.

No, because the outcome is different for every company.

Whether or not to apply best practices depends on where the most value can be created. For example TPM will not be applied by a maintenance organisation that has to focus on costs. Best practices always have to be translated to a companies’ specific situation. All too often RCM or TPM implementations fail because the feasible ambition level within the maintenance organisation wasn’t taken into account. Therefore the most valuable maintenance organisation is a custom made solution by definition.

One of the founders and managing partners of Mainnovation, Mark Haarman is an expert in maintenance and asset management and is the author of Value Driven Maintenance, new faith in maintenance.

CONDITION MONITORING

The Acoustic Emission (AE) technique is based on the detection of the high frequency component of naturally occurring stress waves (or structure borne elastic waves)

CONDITION MONITORING

based on acoustic emission comes of age There was a time when AE was regarded only as a means of monitoring defect growth in stressed materials and structures.

Despite numerous instances of its successful application to machinery condition monitoring since the 1960’s these successes tended to be dismissed by the Condition Monitoring (CM) community as being oneoffs and not relevant to main stream applications; a fair comment in its time since the AE equipment used was seldom suited to use by shop-floor personnel.

Today, however, the situation couldn’t be more different; interchangeable AE sensors are available and easy to use signal processing routines have been developed which make interpretation straightforward. As a result, AE is positioned as one of the four principal CM techniques alongside Infra-red Thermography, Lubrication Management & Analysis and Vibration Analysis as specified in ISO 18436. Furthermore, AE has its own CM standard ISO 22096 (Condition monitoring and diagnostics of machines – Acoustic emission) and ISO traceable certification of CM practitioners is available to Levels 1, 2 & 3.

Whilst these developments represent the culmination of much hard work undertaken by key AE practitioners over recent years they have only been made possible by the unique attributes of AE in the CM role which deliver important practical benefits for industrial use :a) A high Signal to Noise Ratio (SNR), which means that the presence of a small fault gives rise to a large change in the detected signal, giving AE the

following inherent benefits : sensitive to faults at an early stage the presence of a fault can be detected without having to first do a frequency analysis very slowly moving machinery can be monitored a broad range of fault types can be simultaneously detected b) It is based on the omni-directional detection of propagating high frequency waves, which simplifies AE detection and sensor installation in the following ways : there is no need for sensors to be mounted in specific orientations there is no need for sensors to be mounted in the same plane as bearings it is not necessary to consider the possibility of the sensor being mounted on a node or anti-node on the machine surface cross-talk or interference from adjacent machinery is seldom an issue it can be applied in noisy and high vibration environments The many benefits of AE listed above have underpinned its success as a routine CM method to assist maintenance personnel and not surprisingly it is incorporated in both portable CM instruments and permanently installed monitoring systems.

A key to the continued growth of permanently installed monitoring systems in industry is ease of integration into existing shop floor monitoring and control systems. Because of the high frequency nature of AE sensors, in the past this has necessitated the use of an AE instrument

to pre-process the signals. However as an example of the growing maturity of AE technology in the CM role, recent development have led to smart AE sensors (such as the MHC-DS1 - see photo) in which the entire AE instrument is integrated within the sensor itself. Such a smart sensor approach overcomes the difficulties for the end user of having to deal with high frequency signals and coaxial cables but instead has preprocessed DC and switched outputs on twisted pair cables for direct connection to PLC, SCADA etc.

In terms of machinery protection (i.e. detecting gross mechanical failures as they happen) rms responding and switched output Vibration sensors are a familiar site on the shop floor but such sensors are not suited to the CM role. This is because the benefits of CM, maximising machine utilisation and minimising maintenance costs, rely upon an early warning of degradation in order to allow the timely planning of appropriate service and maintenance activities. It is in this CM role that smart AE sensors look set to play an important part as a natural compliment to machinery protection sensors; in the foreseeable future they may even become as ubiquitous.

Trevor Holroyd is the Managing Director of Holroyd Instruments Limited and has been continuously active in the development and use of AE for industrial monitoring since 1974.

With many companies adopting lean manufacturing techniques, it seems that real risks are being taken. It stands to reason - if you cut down your spare capacity, remove your buffer stores and most of your WIP, your plant must be reliable and very well maintained in order to operate effectively.

Leaving major disasters, such as fire aside, a staggering 70 per cent of companies without effective risk management and business continuity plans suffer unplanned plant downtime at least once a year. As ever, maintenance is fundamental to plant availability or uptime, so effective maintenance is an essential part of strategic risk management.

Good maintenance is also a critical component of the lean ethos. Traditional manufacturing had lots of slack in the system however, as buffer stores are removed to improve flow through the plant, the ability to recover

from a breakdown also disappears. Lean may be the ‘in thing’ but it’s not effective unless you improve your maintenance methods at the same time.

Employee engagement is also vital within the lean maintenance mix. During loss management for example, you need to know what’s failing, when and for how long. A well trained operator is a mine of information who can provide much of the information needed to analyse performance issues. If the process can offer some real-time information in return, this will drive improvements at all levels.

It makes sense to keep the technology simple: sense when the machine stops electronically and record the stoppage time automatically.

Ask the operator to identify the reason for the stoppage at the time the event occurs and provide them with facts such as current performance, time to finish and worst stoppages.

For more information quote EMS Enquiry No. 121 on IBC

EMS September/October 2008 www.engineeringmaintenance.info

When the operator begins to point out long-standing minor stoppages and the true effects on performance the process is really working.

It’s worth mentioning that a push button, two line LCD screen is unlikely to enable this effective two-way information sharing. In order to engage with operators, we need to provide them with quality touch panel PCs for data capture and operator feedback, as well as single point lessons, standard operating procedures and fault diagnostics, to help the operator improve performance.

Improved measurement can also dramatically enhance performance. Good maintenance relies on an effective system that understands, and preferably talks to, the OEE management system. The key is to make every asset, every unit of energy and every second, count.

INDUSTRIAL PROTECTIVE COATINGS

Belzona Polymerics Ltd has a solution for improving the efficiency of pumps, significantly reducing operating costs

INCREASED

pump efficiency Belzona has seen pump applications increase dramatically of late, as companies seek to minimise running costs by tackling issues of reduced efficiency. According to National Sales Manager, Gordon Cairns, the number of repairs undertaken by the group has nearly doubled in the last two years, more than any other type. He commented: “Many companies are now working hard to reduce energy consumption, which forms the major part of a pump’s running costs.”

Independent testing from the Department of Trade and Industry at the National Engineering Laboratory, in Glasgow, has backed up Belzona’s claims of increased efficiency as a result of applying a smooth

hydrophobic coating system. Tests showed efficiency increases over new pumps of more than 5%. This, supported by industry knowledge that efficiency losses due to erosion corrosion can be 12 or more percent certainly substantiates the argument in favour of a Belzona coating solution.

Belzona’s partner contractor, SPP Pumps, has passed on the benefits of applying a Belzona efficiency enhancement coating system to its many customers.

SPP Pumps Business Manager, Martin Bagg, explained: “For a number of years, we have used Belzona 1341 (Supermetalglide) as an internal coating for split case pumps.

The coating is generally utilised for efficiency enhancement where experience

has shown that an improvement of around 2% can normally be achieved”.

In addition to the initial efficiency enhancement, the coating also assists in maintaining the condition of the pump over time as it acts as a barrier to erosive and corrosive deterioration of the casing’s internal surface.The coating has also been recognised due to its ease of application and its certified approval for use in contact with potable water.

INDUSTRIAL PROTECTIVE COATINGS

Belzona Polymerics Limited has introduced a scheme to differentiate and reward specialist service centres that invest heavily in surface preparation equipment and are dedicated to maintaining high levels of application procedures and customer service

NATIONWIDE NETWORK

of authorised coating centres launched To receive recognised status as a Belzona Authorised Coating Centre (BACC) service centres must first win the endorsement of a ‘Belzona Champion’, who nominates the company for assessment. Here, they will demonstrate up-to-date equipment and facilities, a dedicated coating room and temperature controlled area and, crucially, ongoing staff training in Belzona approved application techniques.

Steve Cooper, Commercial Manager for Belzona said, “The BACC concept was created to distinguish between regular machinery and equipment contractors and a specialist group of service centres that go the extra distance”.

BACC certified centres receive valuable sales and marketing support from Belzona, including referrals, lead and appointment generation and integration to national advertising and PR campaigns. They also

have the benefit of sales and technical training that keep them at the forefront of product and application breakthroughs; invitations to leading industry seminars; access to more ambitious contracts and a relationship with an industry leading international company.

The BACC network allows Belzona to broaden its service offer and reach.

Customers receive a full turnkey repair service on rotating equipment, such as pumps, fans, blowers, screw conveyors and agitators. This covers mechanical repair and replacement, as well as preventative long term coating protection.

Steve Cooper further commented, “This gives us the platform to target key industries that require a “total service”. These include Petrochemical, Power, Paper and Water”.

BACC status has already been granted to four companies. One of the latest to be presented

24 EMS September/October 2008 www.engineeringmaintenance.info

with an Authorised Coating Centre certificate is Hertel, Wilton Workshops, Teesside. Hertel is an international industrial services company, which builds, maintains, modifies and dismantles plants and installations for the (Petro) chemical, Process and Power industries.

Annette Salter, Workshop Manager said: "We have built up an excellent relationship with Belzona sales and technical people over the last 10 years, both at the Harrogate headquarters and across the UK. This partnership has allowed us to enter accounts together and secure business that, individually; we would have been unable to win”.

LIGHTING

Oil and gas giant Shell UK Limited has just completed an extensive lighting upgrade programme across twelve of its North Sea oil platforms, which involved the removal and installation of several thousand explosion-proof fluorescent lighting units

FLUORESCENT LIGHTING CUTS

maintenance and installation costs The programme is part of a much larger Enhancement & Rejuvenation project at Shell, which in-volves not only emergency lighting, but also other types of electrical equipment located in hazardous areas, including pumps, generators, switchgear, motors and control equipment. The programme is currently being expanded to include Shell U.K.’s onshore facilities.

For the lighting units, the original supply agreement between Cooper CrouseHinds (UK) and Shell U.K. Exploration and Production Europe, was made back in 2005. The eight-year contract involves the supply of lighting to both onshore and offshore installations, from Cooper CrouseHinds’ CEAG eLLK 92 range of fluorescent light fittings. The lights have been fitted to both indoor and outdoor locations across the12 Shell North Sea oil platforms. As part of the contract, technical support and installation training were also provided by Cooper Crouse-Hinds (UK).

John Ferguson is Senior Electrical Engineer at Shell U.K. He works in the Project Engineering de-partment and is also Technical Authority for Electrical Discipline Support at Shell U.K. Exploration and Production Europe. He comments: “In 2005, we evaluated three suppliers of explosion-proof fluorescent lighting. We needed to replace most of the fluorescent lights across twelve of our off-shore oil platforms, for obsolescence and other agerelated reasons. In awarding the contract, the key drivers for us were cost of ownership of the lighting and a range of other factors that were weighted and

scored accordingly. These factors included ease of installation and maintenance, warranties and innovation – the most important factor being ‘Product Reliability’.

This, in the end, led us to choose Cooper Crouse-Hinds UK, who scored very well in all these areas.”

Quality and reliability of the lighting were key factors for Shell. As Ferguson recalls: “Since 2005, in excess of 10,000 light fittings have been supplied to us and only around 20 fittings have had to be returned to the supplier. However, only two or three of these were due to design or technical faults with the product – the rest were because of incorrect installation on our behalf. Overall, we are very satisfied with the quality and reliability of the lights.”

Ease of installation and maintenance of the light fittings were also critical factors in selecting the lighting supplier. As Ferguson explains: “Cooper Crouse-Hinds went the extra yard for us by pro-viding a handy, pocket-sized reference guide for all our maintenance engineers and technicians.

This includes important installation and maintenance information and is very easy to use. In fact, most of our technicians now carry a copy in the pocket of their overalls.”

Cooper Crouse-Hinds UK also provided on-site installation training. “On the technical support side, Cooper CrouseHinds reacted very quickly to any queries that we had. In one particular example, the company modified the design of its light fitting ballast by incorporating new circuitry that detects the early stages of the tube ‘end-of-life’ phenomenon and

shuts down the fitting, thus avoiding a potential overheating problem with the fluorescent light. We were very pleased with such a fast response from their R&D team on this matter.”

The eLLK 92 range of fluorescent lighting units are available for ATEX Zone 1, Zone 2, Zone 21 and Zone 22 hazardous areas. The lighting units come in 2, 4 or 5 feet lengths, with twin lights. The 2 and 4 feet versions can be supplied as emergency lighting. These versions have an ‘intelligent’ NIB battery fitted, which monitors the lighting, providing onboard maintenance with LED indication for ‘capacity’ and ‘faults’. The eLLK 92 fluorescent lighting units are designed with a glass fibre-reinforced plastic enclosure and a polycarbonate protective bowl. The units are protected to IP66 (EN 60529).

Permissible ambient temperatures are from –20°C up to +50°C. This emergency light unit formed the bulk of the supply for the Shell offshore refurbishment project. www.ceag-crouse-hinds.co.uk Reader Reply Number: 318

BEARINGS

Robin Kyte, Sales Manager at The Barden Corporation (UK) Ltd, explains why bearing obsolescence is so important when it comes to safety-critical applications such as aircraft systems and nuclear power plant applications

The problem of

OBSOLETE BEARINGS Locating and sourcing a supplier of an obsolete mechanical component such as a bearing, is a growing concern for many organisations, particularly if the component is part of a safety-critical system on an aircraft or nuclear power plant application.

Sourcing a bearing for a mechanical system on a military aircraft, for example, can be a challenging process, particularly if the system is an ageing one. The aircraft itself may have been in operational service for more than 40 years and may also be projected to remain in service for many more years to come. However, if the operator needs replace the original bearings, the original supplier of the component may have ceased to exist, is now re-located overseas, or perhaps is no longer willing to manufacture the equivalent bearing in such small volumes (less than 1,000 units). This means that many aircraft (and other mechanical) system operators and managers are now facing significant bearing obsolescence issues, particularly if the quantity of bearings they require is relatively low.

In addition, there may be other design features about the bearings that make it equally unattractive, or even impossible, for a supplier to adhere to. For example, the bearing may require special materials, special lubrication, certification, special features such as tapered outside diameters, or may need to fit an Imperial chassis size.

There are similar issues in the nuclear industry too. Bearings are commonly found in nuclear power plants as part of actuation systems, which position the control rods into the fuel bundle. In an emergency situation, the control rods are dropped into the fuel bundle to absorb the reactor heat, which dictates that the bearings must not, under any circumstances, fail. This means bearing suppliers must offer full manufacturing traceability, controlled lubrication and complete retention of records, similar to the aerospace and defence industry.

The solution for the system operator is to find a bearing supplier who is able to manufacture the specified bearing to the same (or higher) quality standards as the original and who is also willing to supply in small batch sizes, anything between 10 and 500 units. Robin Kyte is a Sales Manager at Plymouth-based bearings manufacturer The Barden Corporation (UK) Ltd. The company manufactures a range of super precision angular contact and deep groove ball bearings. The focus is on special configuration bearings that add value and provide engineered solutions for the customer. As Kyte states: “In the UK and most of Europe, the problem of obsolete bearings is predominant in the military aerospace and nuclear sectors. The problem usually arises when the mechanical system is very old, usually more than 25 years. In this scenario, many

26 EMS September/October 2008 www.engineeringmaintenance.info

customers approach Barden because we are willing to manufacture direct replacement bearings in relatively small batch sizes and we have the manufacturing capability to produce special engineered bearings. Barden also have a strict non-obsolescence policy.”

Barden bearings are manufactured and controlled under strict aerospace procedures that the company employs, providing full traceability, controlled lubrication and complete retention of records.

“Often the bearing drawings on such legacy products will define only the chassis size, with little or no information regarding the internal design, materials or tolerances. With such a basic specification, a wide range of bearings could meet the requirements, ranging from low precision, commercially-produced bearings to high precision bearings with full traceability and inspection,” says Kyte.

“Some of these bearings may be relatively inexpensive to buy, but they were never designed to operate in these types of environments or applications.

Often, the buyer doesn’t actually realise that the bearing they have just purchased is not a like-for-like replacement. Certification, full traceability and quality should be the key issues here,” he advises. www.bardenbearings.co.uk Reader Reply Number: 319

PREDICTIVE MAINTENANCE The water industry is increasingly turning to predictive maintenance as it addresses the challenge of improving asset performance. Artesis has successfully combined advanced technology with a cost-effective implementation to meet their current and future needs

simplified predictive maintenance

FOR WATER INDUSTRY The nature of the challenge There is an increasing pressure on water companies to maximise the performance of their physical assets, a critical factor in optimising shareholder value and customer service. The water industry regulator (Ofwat) reviews the prices that companies charge, and takes into account the benefits of the capital investments planned and improvements in operating efficiency. This approach has forced water companies to focus on asset effectiveness in order to find the right balance between replacing existing equipment and developing new maintenance strategies.

The scale of the challenge is huge. United Utilities, for example, provides water and wastewater services to 7 million people in the North West of England. To achieve this, it maintains an asset base of more than 120,000 pieces of equipment on 3,540 sites, requiring an annual operating budget of ÂŁ371 million.

Adopting predictive maintenance Predictive maintenance initiatives in the water industry have become more accepted and widespread with the increased use of Reliability Centered Maintenance (RCM).

This provides an analytical framework for the selection of maintenance strategies based on the identification of failure modes, their effects, and their impact on the business. For each asset, the most appropriate strategy might be to run to failure, to maintain based on fixed time or operating intervals, or to predict future failures based on measurements.

Although run to failure is a common strategy, both in the water industry and elsewhere, it can lead to high costs resulting from loss of availability, secondary damage, and excessive spares inventory.

Planned maintenance is recognised as more cost-effective than run to failure for a wide range of equipment but often results in unnecessary maintenance interventions that can themselves introduce problems.

Predictive maintenance has become the preferred technique for critical assets in many industries, not only because it brings significant cost benefit advantages but also because it improves the level of control that engineers can exert over the future performance of their assets.

Predictive maintenance solutions Predictive maintenance typically relies on the implementation of a condition monitoring system, used to collect and analyse the measurements that allow the diagnosis and assessment of potential failures. For machinery, vibration-based systems have successfully been used for large, critical assets but have often proved expensive and difficult to interpret when applied to wider populations of equipment. Specialist techniques like oil analysis, motor current signature analysis, and infra-red thermography have proved excellent for detailed fault analysis once a potential failure has been identified in specific types of equipment, although they are each limited by the range of faults that can be detected.

Artesis MCM technology The recently introduced Artesis predictive maintenance system provides all the benefits of traditional condition monitoring systems at a fraction of the complication and cost. Originally developed under a NASA contract, Artesis MCM (motor condition monitor) uses an intelligent, model-based approach to provide complete monitoring and diagnostic capabilities for most electric motor driven equipment.

Each small monitoring unit covers a complete motor and the equipment driven by it, and is typically installed in the motor control cabinet. Since connections are required only to the motor supply cables, installation costs are low with no need to access the driven equipment for any sensor installation. Once installed, the system trains itself to recognise normal performance, following which it

continuously monitors the equipment for possible faults. When such a fault is detected, the system provides a diagnosis of one of a wide range of mechanical and electrical problems, and indicates severity so that the user can make decisions on the most appropriate intervention.

Artesis MCM has proved very attractive to water companies, and has also been successfully implemented in a very wide range of other industries. Because it is simple to install and requires little user intervention in operation, it combines low start-up costs with the significant benefits of predictive maintenance. Since it doesn’t require any sensor installation on the equipment itself, Artesis MCM is a particularly good solution for inaccessible equipment like submersible and borehole pumps. All diagnostic analysis is carried out in the monitoring unit itself, reducing the need for extensive communications between remote facilities and centralised control rooms.

Water industry solutions In a typical water industry application, Artesis MCM has been used to monitor a wide range of equipment providing water services to a major city. The water company, faced with the need to provide water to ever-higher standards and to become more cost-effective while coping with rapidlyincreasing demand, embarked on a set of initiatives to move from breakdown to predictive maintenance. As they had little existing diagnostic expertise, they needed a system that would do most of the routine analysis for them. And because much of their equipment was located in remote sites spread out over a wide area, access problems meant that they required a permanently-installed system. Trials and operational implementations of Artesis MCM are now taking place in many water companies in the UK and around the world. www.www.artesis.com Reader Reply Number: 320

CONTROL AND INSTRUMENTATION Samson Controls excel in providing optimum control for temperature regulation at London’s top exhibition venue

CONTROL VALVES HELP

ExCeL minimise energy costs

Achieving energy savings at ExCeL, London’s prestigious exhibition centre has always been a key objective, but especially valid today as a result of ever-rising energy costs. Opened in 2002, ExCeL has become the established ‘home’ for some of the UK’s best known events, such as the London Triathlon and the London Boat Show. The centre has 90,000m2 of events, conference and meeting space, as well as cafes and restaurants. A typical exhibition hall would cover about 6400m2 and as a result of the flexible layout of the halls, adjacent halls can be easily joined together, with single halls of up to 3200m2 possible.

As the centre is a year round venue, with almost limitless combinations of halls available, consideration was given to creating the most energy-efficient methods of heating and cooling the various exhibition spaces. Clearly, it was important that the energy costs could be optimised for a wide variety of demands ranging from only a few halls in use, to all the halls being occupied.

To help achieve the key objectives, variable speed pumps for water circulation in

the extensive heating and ventilation systems, were utilised to realise the potential for significant energy savings, especially when demands were lower. To ensure that the water distribution worked as the designers intended it was important that Differential Pressure Regulators were installed as the primary balancing device.

Enter Samson Controls, who provided over 225 valves ranging in size from series 45 valves, up to size 400mm series 2333 valves.

The 400mm valves are some of the largest globe valves manufactured and were installed to handle flow rates as high as 375 lit/sec. The use of very large valves, which have to operate against high pump heads, requires special construction and this was a challenge which Samson was pleased to accept.

The Samson valves enabled speedy commissioning of the water distribution network because each sub-circuit could be set independently of each other circuit, without the need to go back and adjust previously set circuits. The large stocks of valves held by Samson in the UK enabled the project to be completed to tight

ENERGY MATTERS

As part of a company wide energy drive, Victor Manufacturing has realised 48% energy savings per annum on their compressed air related energy costs by installing an energy efficient Boge SLF40 frequency controlled screw compressor

ENERGY SAVINGS

to catering equipment manufacturer Victor Manufacturing is a leading commercial catering equipment manufacturer. At their manufacturing site in Bradford an extensive range of food service equipment is manufactured which is used by all kinds of organisations such as hotels, restaurants, hospitals and universities to move, store and serve hot and cold foods.

Compressed air is used within the manufacturing process to power various applications such as the assembler’s air tools.

In recent months all areas of energy usage at the facility have been reviewed as part of a company wide energy drive. As such, Victor Manufacturing invited The Carbon Trust to audit the compressed air system and assess its energy efficiency.

Amongst the recommendations made, the Carbon Trust identified that energy savings could be made by replacing the existing compressor with an energy efficient version.

At this stage Bob Morris, the Production Supervisor, invited current compressed air partner Boge Compressors to review the system.

Dale Cellier, the Area Sales Manager at Boge Compressors consequently conducted an audit of the existing system to provide recommendations. The audit verified those of The Carbon Trust – that energy savings would be made by replacing the existing compressor with an energy efficient compressor.

The Boge SLF40 frequency controlled screw compressor was recommended.

Bob Morris said “The quantified energy savings were significant enough to convince us that investing in an energy efficient compressor would pay off in the long run.

Our experience with Boge to date has been excellent. We already had one Boge compressor installed over 12 months ago to power the laser cutting application which had run satisfactorily. In that time Boge had provided us with excellent service and backup support. As a result we chose to install a Boge SLF40.”

The Boge SLF series combines a direct coupled drive system with frequency control to provide the ultimate compressor for pressure control under variable output requirements. The SLF is therefore a low

30 EMS September/October 2008 www.engineeringmaintenance.info

carbon technology that works strictly in accordance with the compressed air demand by producing the exact volume of compressed air at the pressure required.

Frequency control minimises idling time and evens out air demand fluctuations. For Victor Manufacturing this meant creating a 48% reduction in their compressed air energy costs per annum!

Bob Morris concludes: “We have since been very satisfied with the performance of the Boge SLF40 – we don’t have to think about the compressor system anymore – it’s just doing its job, saving us money and contributing to our all up reduced carbon footprint!” www.boge.co.uk Reader Reply Number: 322

LEAN MAINTENANCE

Leicester based Cressall Resistors has put in place a lean programme, managed by manufacturing director Cy Wilkinson, that has helped increase turnover by 100 per cent in 18 months

LEAN PROGRAMME helps increase turnover The fundamental strategy was formed through the use of eight lean tools: value stream mapping, 5S, standard work, flow, pull, TPM (Total Productive Maintenance), mistake proofing and set-up reduction.

After producing a strategic plan, Wilkinson began the implementation process by providing uniforms for the manufacturing team and implementing a set of external lean training courses. These courses resulted in improved manufacturing efficiency and provided staff with the chance to obtain an NVQ Level two qualification. During the sessions, teams of five or six delegates focused on a particular area and carried out a kaikiaku (blitz) to deliver focused improvement, usually resulting in implementation of the first three 'S's (sort, straighten and shine) of 5S and a new layout to improve flow.

Cressall Resistors now has on ongoing training programme consisting of four day

seminars attended by a cross-functional teams consisting of shop floor operatives, sales engineers, designers, planners, engineers and directors.

In order to improve sale to delivery times, Cressall tackled the 'order entry' to 'issue to manufacturing' part of its process.

The company took a snapshot of the situation, using value streaming techniques, which highlighted areas of concern such as bottlenecks, delays and duplication of work and information, before developing ways to counteract these weaknesses.

This has resulted in major improvements in contract review and file location, information consolidation, shop floor access to CAD files and purchasing.

The company also applied its lean strategy to the manufacturing process, which reduced used-space by more than sixty per cent; reduced part associated employee movement and implemented single piece flow to reduce

WIP (Work In Progress). A Kanban was established to manage component inventory and the time needed to complete a physical stock-take was reduced by 50 per cent thanks to the 5S workplace organization.

"When I joined Cressall in June 2006, there had already been several attempts to roll out 5S and to implement flow, all with varying degrees of success," explained Wilkinson. "Though there was impetus from senior management, these earlier lean attempts failed due to lack of follow-up and buy in from the work force."

As well as tackling the present, Cressall has also made plans for the future. There are a minimum of six lean events happening at the company in 2008, and a minimum of 24 employees who will go through the Business Improvement Techniques NVQ formal qualification. www.cressall.com Reader Reply Number: 323

MECHANICAL ENGINEERING

War Pilots reunite with English Electric Lightning plane for honour award

BEST OF BRITISH is simply supersonic A British Cold War plane which soared through the skies with supersonic speeds of more than 1,500 mph is to receive its own ‘medal of honour’ in Warton, Lancashire.

Former pilots and staff who worked on the English Electric Lightning will be reunited with the plane (an FMk.6 registered XS928) at its current ‘home’ at BAE Systems to see the Institution of Mechanical Engineers’ (IMechE) honour it with an Engineering Heritage Award. Only 45 such awards have been made in the scheme’s 21 year history which recognises innovation and excellence in mechanical engineering.

In total 339 of the aircraft type were built – today just four remain that are able to fly. Back in the Fifties and Sixties, BAE Systems’ facilities at Preston, Warton and Samlesbury were hives of activity as thousands of Lancashire aerospace workers cut new ground by delivering one of the fastest fighters the world has seen.

Chartered Engineer, Professor Isobel Pollock, Chair of IMechE Heritage Committee said: “This is not just one of the world’s most proud engineering creations – it is an example of British excellence that made the rest of world sit up and notice. This year marks 50 years since it first reached Mach 2 – twice the speed of sound, so bestowing a heritage award on something that is still making history today is amazing.”

A stalwart of the RAF for a record 28 years, it was also used by the Saudi Royal Air Force. It was specifically designed as a point defence interceptor, essentially a guided missile¬armed, air superiority fighter with an aim to defend mainland Britain against bomber attacks. One of the criteria that made the Lightning a cut above its piston¬powered predecessors was its ability to ‘dash’ to heights of

18.3 km (60,000 feet). It even had a nickname of ‘Frightening’ in some cases, not just because of its challenging crosswind landing but its thunderous roar. Only experienced pilots were assigned to fly it.

British engineer W.E. ‘Teddy’ Petter designed the Lightning, having previously designed Britain’s first jet bomber ¬the Canberra ¬an aircraft so fast the Ministry of Supply realised that virtually no fighter could catch it – and if the Soviets could produce something similar then Britain would need a supersonic fighter to deal with any counter threat.

Simon Howison, Engineering Director, for BAE Systems Military Air Solutions business, said: “It is the spirit that gave birth to the Lightning that drives much of what we still do today at here at Warton.

We are still pushing boundaries, still

striving to astound through innovation and delivery and we are still getting the results. Indeed the F¬35 Lightning ll – the namesake of the original Lightning that we are now engaged in at Samlesbury is testament to that.”

He added: “It is a fantastic honour for us to receive this Award, and it is a tribute to all those who worked on such an incredibly ambitious and ground¬breaking programme. Few aircraft carry a reputation like that of the Lightning – still fewer have achieved similar levels of capability. Days like today remind us all that the UK can and should be proud of what it does in the fields of engineering and technology.” www.imeche.org Reader Reply Number: 324

ADVERTISEMENT FEATURE

Identifying particulate contamination is key to predictive maintenance.

Particle contamination in hydraulic oils and lubricants can have a significant impact on system efficiency, safety and operating costs. This is especially true in modern high performance systems, where tolerances are becoming ever tighter, and where equipment is used in critical industrial, mobile and process applications.

Together, we can ensure that fluid contamination doesn’t compromise your maintenance programme.

Parker’s IcountPD represents the most up-to-date technology in solid particle detection; delivering countless advantages to maintenance engineers worldwide.

The design dynamics, attention to detail, and small size of the permanently mounted, on-line particle detector combine to deliver a truly innovative product. The laser based, leading-edge technology means the IcountPD is a cost-effective market solution to fluid management and contamination control.

Recognising this fact, Parker Hannifin has developed innovative contamination monitoring technology that measures both the size and concentration of particles in oils and lubricants. The latest IcountPD particle detector is based on the company’s 20 years experience of particle analysis, and of working with customers in building predictive maintenance programmes.

IcountPD is designed as a simple to fit and operate instrument, that provides plant and maintenance

engineers with an extremely accurate, reliable and cost effective method of particle detection.

IcountPD can be permanently fitted on-line to any hydraulics or lubrication system and features proven laser detection technology for precise and repeatable particle detection. The instrument provides a continuous indication of the quality of oils or lubricants, with an easy to read digital status display, backed by appropriate alarms, to confirm that operating conditions are within safe parameters or are changing due to fluctuations in contamination levels.

With the ability to be used at flow rates from 6 to 380 l/min and at line pressures from 2 to 420bar, a choice of output signals, including 4-20mA, 0-5V, CANBUS, J1939 and RS232, plus an optional moisture sensor, IcountPD is ideal for a wide range of industrial, process and mobile applications.

PLANT EFFICIENCY

Monitoring critical components inside a hydraulic pump, fan, blower or compressor, can improve plant efficiency, eliminate production downtime and increase the operating life of plant equipment, says Ian Taylor of Corus Northern Engineering Services (CNES)

Improving life expectancy Although the cost of a component inside a hydraulic pump, such as a rolling element bearing, rotor or fastener, is often small compared to the total cost of the pump, the cost of production downtime and losses caused by component failure, are often significant.

For a processing plant, the typical cost of production downtime can equate to hundreds of thousands of pounds per day, however there are numerous technology safeguards out there that, when compared to the cost of lost production, are relatively inexpensive. They use the latest condition monitoring and predictive maintenance technology, including acoustic emissions monitoring, vibration monitoring and thermography, to protect plant and machines.

Business development engineer plant condition monitoring at CNES, Ian Taylor, said: “At Corus, we monitor all pumps, some every week, but each pump at least once per month. Where the pump is critical to our production process, such as the hood cooling pumps on our basic oxygen steelmaking plant, we have installed fixed CM systems to monitor the plant 24/7.”

Condition monitoring prevents maintenance teams replacing components unnecessarily and introducing possible new and unrelated problems. A number of techniques are available and these can be used individually, or in combination to protect the company’s valuable assets.

Good vibrations Taylor explained: “As most pumps run at a steady load and speed, patrol monitoring with vibration analysis equipment is usually the most effective condition monitoring technique however, it depends on the pump design. Acoustic emissions monitoring may be more effective if the pump speed is less than 80rpm or if the maintenance technician wants to monitor the condition of plain bearings inside the pump or motor.”

Vibration monitoring can identify a number of potential pump problems, including misalignment or coupling issues; mechanical looseness inside the pump, through to the condition monitoring of rolling element bearings; cavitation issues; or rotor erosion. Wear of gear teeth on gear pumps can also be monitored using vibration analysis.

Standby pumps are another application where vibration monitoring techniques can be useful. Companies often operate two identical pumps on a common bedplate, one as duty and the other as standby.

Unfortunately, constant vibration from the duty pump can cause bearing problems on the standby pump, referred to as false brinelling. Once the standby is switched on, it very quickly fails, resulting in two pumps out of service.

Perfect acoustics For hydraulic systems that rotate at less than 80rpm and operate under fluctuating load conditions, or only move through a part revolution, it is more difficult to collect meaningful data using vibration monitoring.

For this reason, CNES has developed its own, patented acoustic online condition monitoring system, Aquilla AE Pro. Acoustic emission monitoring equipment has a high sensitivity to machine faults but is also immune to audible noise and low frequency background vibration. It works by detecting the high frequency stress waves generated within a material during crack growth, plastic deformation or phase transformation. Surface-mounted transducers detect these stress waves, which lie within the 25kHz to 1MHz frequency range.

“The problem,” warns Taylor, “is that many companies do not possess the skills in-house to interpret data from acoustics emissions monitoring effectively.”

Correct selection of lubricant or hydraulic fluid can also significantly reduce component wear and associated energy costs. Analysing the level of degradation and debris present helps asses lubricant efficiency and facilitates correct lubricant selection and oil change periods. CNES can also monitor the condition of hydraulic fluid, ensuring a longer life of system components at minimum cost. www.corusnes.com Reader Reply Number: 325

Artesis MCM – Advanced Technology for Simple, Effective Condition Monitoring

Every now and then, a new solution comes along and changes your thinking.

Artesis MCM is a new approach to condition monitoring, providing all the benefits without the complication and costs of traditional systems.

Artesis MCM monitors the condition of equipment driven by electric motors, using the motor itself as a sophisticated transducer. It requires only connection into the motor’s electrical supply, avoiding the need to attach specialised sensors to the plant. Because Artesis MCM is permanently installed, it provides continuous fault monitoring and doesn’t require the manual data collection that represents a major cost of using walkaround systems. So Artesis MCM is especially applicable to situations where the plant is not easily accessible, either because it is remote or because the local environment is hazardous.

Artesis MCM uses advanced technology developed for NASA to bring you a selflearning capability in a compact, panel-mounted instrument. Over the initial period of operation, it teaches itself about the normal operation environment of your equipment so that it can accurately identify and diagnose faults when they start to occur. Artesis MCM doesn’t demand specialist setup or operating expertise, it just tells you what you need to know, when you need to know it. If you want all A S the benefits of condition monitoring but think it’s too difficult or expensive for you, Artesis MCM will make you think again.
