Predictive Maintenance Services (PdM) will save you money by detecting bearing faults before they can cause catastrophic failure of the compressor or motor. As industry specialists know, an unplanned shutdown will cost a company thousands of dollars in lost production. With rotating equipment, vibration monitoring frequently offers the fastest and biggest payback by increasing the time between rebuilds and providing early warnings of potential machine problems. Overall vibration readings will not detect the early stages of bearing defects until it's too late. The early stages of bearing wear can only be detected by analyzing the spectra of their high frequency envelopes. Below are the actual bearing defects in a rotary screw compressor. This FES Model 32L has defects in the female rotor bearings, Vibration analysis caught the problem before the compressor had catastrophic failure.
This Compressor motor has a high 2x Line Frequency Amplitude, indicating a rotating variable air gap between the rotor and stator. An electric repair shop replaced the faulty motor before it had a catastrophic failure. Vibration analysis will detect this problem and other motor problems. PdM Services can tailor a Predictive Maintenance Program for your plant and provide you with a report of any faults that are detected. Not only are we experts in compressor vibration analysis, we can perform vibration analysis and balancing on your rotating equipment.
