Early Detection Of Bolt Looseness Prevents ReCip Failure

Predictive Maintenance Analytics Enables Early Detection & Targeted Action

Observations​

  • A rapid rise in total vibration energy (TVE) levels was flagged via our email alarm notification for a reciprocating compressor.
  • Vibration trends monitored on compressor bearings showed increasing values.
  • Vibration values on cylinder 1 showed a sharp and significant increase.
  • Upon spectrum analysis, cylinder looseness was suspected and identified to be the primary cause for this upset.

Alarm raised on Shoreline APM Platform

Supporting Data

Users received links to the data collected by Shoreline APM platform, showing the rapid increase in readings from specific points where the looseness was starting to deteriorate. A rapidly rising trend on Cyl 1 was predominantly visible.

Evidence Of Success

Upon inspection, cylinder support bolts on compressor Stage 1 were found to be loose. These bolts were tightened.

Additionally, at least one bolt between the cylinder and the distance piece had come loose, perhaps resulting from higher-than-usual vibrations. This was repaired.

Conclusion:

A timely alarm raised by the Shoreline APM platform resulted in prompt follow-up preventive maintenance actions, saving this machine from a catastrophic failure.
