双螺杆制冷压缩机异常声响的诊断

THE FAILURE DIAGNOSES THROUGH ABNORMAL SOUNDS FROM TWINSCREW REFRIGERATION COMPRESSOR

压缩机是轻烃回收装置的核心设备,其运行质量,直接影响着轻烃回收率,在一定程度上决定着该装置的经济效益,因此对该机组的运行、保养,维护就显得尤为重要,特别是前期的故障判断。采用设备故障诊断技术,对机组出现的异常声响进行分析、诊断,找出故障原因,使设备投入正常的生产运行。

As a key equipment in a light ends unit,the compressor and its operating quality have direct impact on the recovery ratio of light ends,and determines the economic benefit of the unit to a cer- tain degree.Thus the maintenance of the equipment,especially the failure diagnoses at earlier stage,is very important.The abnormal sounds sent by the compressor can be analyzed and diag- nosed to find out the causes of failures,so that the equipment works properly.
