Piston compressors are the indispensable equipment of oil-refining enterprises, the failure of which may lead to a significant decrease of production, and costly repairs, increasing the danger to life and health of workers.
One of the problems, arising from the operation of piston compressors and requiring an immediate detection, is a hydraulic impact. The hydraulic shock is a phenomenon, which is accompanied by an abrupt pressure increase in the decreasing space. The hydraulic impacts can cause the destructions of cylinder-piston group details and emergency situation occurrence.
The implementation of the automatic vibroacoustic condition monitoring and diagnostics of piston compressors COMPACS® allows to successfully prevent downtimes and accidents caused by hydraulic impacts. Diagnostics and monitoring are based on the control of the level of vibroacoustic sensor signal, axially proceeding from the cylinder cover at the moment of approach of the piston to the top dead center and the level of condensate in the separator. However, the diagnosis reliability increasing will always be an urgent task.
