Without monitoring With monitoring 2 Recips can consume five times as many maintenance dollars as an equivalently sized centrifugal compressor. A monitoring system from GE will often more than pay for itself in the first year, and can save millions of dollars over the life of the compressor.
Monitoring vibration & impact Vibration transducers monitoring rotating machinery generate "stationary" signals; this means they have constant frequency content over each revolution of the rotor (Figure 4). In contrast, vibration measurements on reciprocating compressors present both stationary and non-stationary content.
It is remarkable that the first revision of the widely known API Standard 670 was released in 1976. It was named "Non-contacting Vibration and Axial Position Monitoring System," a standard focused on the application of proximity sensor-based machinery monitoring. The second revision of the same standard was released in 1986.

vibration probes (X and Y) shall be installed for a centrifugal compressor with fluid film bearings for shaft vibration monitoring. And the experience also recommends a minimum of one set of seismic vibration sensors to be mounted on the bearing case to monitor the overall house vibration.
Vibration Analysis and related data acquisition for industrial compressor applications. Ammonia screw and reciprocating compressors are a vital part of facilities running refrigerants for frozen food processing or commercial ice production, where cooling load applications are high. The compressors are also utilized in cooling storage facilities.
Monitoring of Operating Parameters Centrifugal Compressors typically produce more air per pound of machine weight than any other of the three major existing technologies, including double acting reciprocating and rotary screw types. This is due to their ability to run at very high speeds. In order to do this and avoid catastrophic failure ...
Vibration Monitoring of Compressors Applications A compressor is used to compress gas from a lower pressure at the intake to a higher pressure at the exhaust by reducing the volume of the gas. Applications are wide ranging, with the greatest applications in the refrigeration, chemical and petrochemical, food processing, pulp and paper,
Monitoring reciprocating gas compressors with 4-20 mA LPS™ vibration sensors Vibration monitoring introduction Vibration monitoring is well established as a tool for diagnosing the mechanical health of rotating machines. Machinery analysts and technicians have been successfully using vibration monitoring of rotating machinery for many years.
"I am seeing a clear compressor vibration increasing trend. Current level of vibration is not very high but a trend is obvious. I do not see any speed/load change on this unit." The vibration was still well below the alert level, but was recognized as abnormal by the remote monitoring specialist.
IMI Sensors offers industrial accelerometers to monitor rotary screw compressors, capable of detecting vibration through a very wide frequency band allowing the user to pick up faults such as pitting, oil injection issues, and rotor mesh.

Jan 22, 2019· Impact measurements have emerged due to the fact that traditional vibration monitoring techniques are hardly suitable for reciprocal compressors. This is due to the significant difference between a vibration signal and an impact signal. A vibration signal is seen as a stationary signal, to which traditional vibration measurements and techniques are applicable.
For reciprocating compressors, the approach outlined above is effective. However, for centrifugal compressors, there is more rotation/potential vibration at work. Equipment can be spinning at 10,000-plus rpms in a centrifugal compressor. Consequently, bearings and vibration monitoring on these compressors is crucial.
In spite of the criticality and importance of reciprocating compressors, they are sometimes unobserved by condition monitoring specialists. A portable vibration analyzer, which is routinely used on rotating equipment, is not well suited for reciprocating machines and has been unsuccessfully monitoring reciprocating compressors for years.
