The reference answers will be visible after responding; points are awarded by identifying the key points. (Unless otherwise specified, all questions and answers are based on hydrogenation units.) ) 1. Excessive vibration in the compressor cylinders, pipelines, housing, and other components ； 2. Large current fluctuations ； 3. Large fluctuations in exhaust pressure and flow rate. Summary thread of Q&A questions for 2017 (updates available now): http://bbs.hcbbs.com/thread-1657793-1-1.html.

The press has cylinders installed in it; the machine vibrates heavily and the temperature is high!
Liquid slugging can occur in reciprocating compressors when they contain liquid. When it’s light, there is a knocking sound and the machine vibrates greatly. The heavy connecting rod broke, causing scratches on the cylinder block; in some cases, the compressor was even destroyed – the damage was extremely severe.
Abnormal vibrations occur in the engine body, cylinders, etc； Significant fluctuations in current ； Flow and pressure fluctuations ； Pipeline vibration, in severe cases, can lead to cylinder collision accidents
When liquid enters the compressor cylinder while it is in operation, the liquid cannot be compressed, which causes it to impact the compressor valves violently, leading to damage to those valves and other components. In the most severe cases, this can result in permanent damage to the compressing parts of the compressor (piston rod, piston body, cylinder).
Water hammer: the sound and vibration increase.
The engine will make unusual noises, and in severe cases this can lead to cylinder collision accidents
