| Abstract: | A model of vibration mechanics was developed by examining the movement law of mini-reciprocating compressors and by studying the vibration principle of valve plates.This paper points out that fault information of valve plates are likely to be found in frequencies when valve plates take rotor frequency as its own frequency and on free vibration components of valve life guards.The model was explicated coupled with case studies and will lay theoretical basis for vibration diagnosis of compressor valves. |
