Only 1% of an electric motor’s lifecycle costs are spend on maintenance

In a recent paper delivered to the Motor Summit in Zurich it claimed that only 1% of the total lifecycle cost of an electric motor was attributable to repair and maintenance. Only 2% represented the initial purchase price. The claim made in a paper entitled ‘Policy Guidelines for Electric Motor Systems’ may not come as Read more…

Raising Reliability

If a repair looks right then the there is a good probability is that it is right. Reliability should be built into every repair that is undertaken with the minimum standard being that of returning the machine (a pump in this instance) to the condition it was manufactured to and wherever possible to improve the Read more…

Pump Cavitation

One of the more serious causes of pump failure is cavitation, CPM see the symptoms of cavitation on a regular basis and through their regular technical updates hope to ensure that engineers are more aware of the symptoms. We are sure that everyone has seen the resultant damage from Cavitation and CPM often advise on Read more…

42% of End-Users employ a reactive electric motor strategy

In a survey of end-users of electric motors performed by our International Trade Association EASA (Electrical Apparatus Service Association) it revealed that 42% of those questioned described their strategy as ‘reactive’ compared with 30% who stated they employed a ‘preventative maintenance’ approach. As a company who see the results of such a strategy and with Read more…

Thermography extends MTBF from 2 years 3 months to 5 years

Long before equipment fails it will experience a significant rise in temperature. Although you cannot physically see this rise in temperature, you can use certain tools to recognise it. The application of thermography detects temperatures via infrared radiation and converts it into visible light, which allows for a condition monitoring engineer to detect static electrical Read more…

Vibration Analysis – Reading the Vibration Signature

Vibration analysis as part of a condition based monitoring program can help to detect machine failure before it becomes an issue and impacts any unplanned downtime. With correct use it can allow for the repair of a machine before the occurrence of an expensive unplanned failure. While there are simple ‘go, no-go’ instruments which will Read more…

Gearboxes and EASA: Best practice repairs

  No one disputes that gearbox overhauls and repairs need to be as good as when the machine was originally manufactured but being EASA-certified, CPM takes it a stage further. The EASA Accreditation Programme was devised specifically for electric motors but with all gearboxes incorporating a drive source, the benefits extend to the driven component Read more…

Managing the risk 100% Uptime can be achieved – A Case Study

Case study – Working with the customer to manage risk Vertically mounted, Ingersoll-Dresser 14HHS 300 multistage centrifugal pumps, driven by a Brook Hanson 110kw Flange mounted 4 pole, 415v ac motors. The duty cycle of these pumps can be extreme operating 24hrs a day and they are highlighted as critical plant by the operator, therefore Read more…

70% operate a ‘run to fail’ strategy

Lots of papers and articles have been written on the costs of industrial downtime caused by the unplanned failure of rotating machines and the consequential effect caused by loss of production, health & safety issues, process contamination and the resources required to get the plant operational again. Much less however, has been written about the Read more…

Asset Failure Reports

Knowing why an asset failed and you’re most of the way towards avoiding it happening again. Sounds so simple but this important part of Asset Management is often overlooked.   There are various steps taken in the event of an asset having failed and from CPM’s experience, almost all plant operators have their own preferred Read more…
