Dynamic Test And Fault Forecast Analysis Of Compressor

The industrial production is becoming more modernization, machines and equipments is becoming larger, more continually, automatization and rapidly, it benefit from improving the productivity and depressing the cost and waster, but on the other hand, the inverse ratio of loss is increased because of the equipment failure and the charge of maintenance increased more and more. Modern equipments usually have advanced technology and complex structure, they need to do a lot of high quality examination. The hidden trouble of the machine is hard to be found by man's experience and sense. Complex and advanced machine isn't easy to be disassembled to check, so we must use advanced instrument and scientific ways to diagnose.This thesis is mainly focus on: By the different gathering signs of SINOPEC QILU LTD. PLASTICS COMPEX LDPE high pressure compressor, we use three technology-parameters technique, vibration technique and oil-liquid technique (also be called medium-metal technique)- to compare and diagnose piston-compressor. And the result is used to dynamic check and failure forecast analysis, so we have time to avoid suddenness shut-down and depress the economic losing.At present, the system of fault diagnoses and forecast analysis of compressor has been opening out successfully. The result that system get by compare and analysis ways is approximately the same as the LDPE compressor what was happened. It will effectually depress the number of the compressor failure and bring a lot of economic benefit.
