Industrial Machine Vibration Analysis and Condition Monitoring

Industrial Vibration Analysis and Condition Monitoring - industrial pumps and motors Parker Kittiwake A condition monitoring system is concerned with the early detection of failure. Vibration monitoring systems, whether they use traditional techniques based on displacement or acoustic emission sensor techniques, form part of your condition monitoring (CM) tool chest. 

Machinery vibration analysis equipment is part of a machine monitoring system that aims to provide months of warning of developing issues before they become bigger problems. This can save your company from serious disruption by avoiding unnecessary downtime and delays. There is also the potential for both on and offline implementation of these systems, subject to capability and level of available technology for the techniques, which makes them perfect for the food and beverage, power generation, marine and offshore industries.

Vibration monitoring techniques

Vibration monitoring equipment uses techniques based on the use of accelerometers, which are well known in the field of CM, and can be classified into three main categories:

VM Vibration Monitoring (ISO 10816): Perfect for maintenance engineers, vibration monitoring ISO 10816 offers an instinctive understanding that a machine is vibrating unusually from the non-rotating parts. Great for small machines, electric motors and pumps and production motors.

VA Vibration Analysis (ISO 13373): A mainstream CM option and essential addition to any other technique used, vibration analysis offers a more sophisticated improvement in signal to noise ratio for repetitive defect signals. This highlights what is internally causing the vibration.

AE Acoustic Emissions (ISO 22096): This technique looks for high-frequency signals from cracks or impact rather than a repetitive movement from vibration. As a passive technique, acoustic emissions can diagnose incipient machinery prior to undertaking a lengthy diagnosis. Highly effective in detecting the very early onset of machinery fault conditions where needed most.
 

Acoustic emission machinery

There are many approaches which fall under the umbrella term condition monitoring, each with its own features and areas of excellence. These include machinery vibration monitoring and analysis, and also acoustic emission analysis systems.

Techniques in BLUE = Technologies available from Parker Kittiwake


Parker Kittiwake focuses on techniques such as an acoustic emission system that provides for the greatest protection or longest period of warning for potential damage and eventual failure. While machine vibration monitoring systems can help prevent the worst cases of damage. 

The use of two (or more) appropriate technologies can provide a more complete picture of the likely failure mechanism, thus offering you reduced machinery downtime and more efficient recovery. The table below identifies the variations of expertise that different condition monitoring options cover.
