离心空压机扩压器损坏原因分析及预防

Analysis of Diffuser Breakdowns of Centrifugal Compressor

湘潭钢铁股份有限公司动力厂离心式空压机扩压器出现普遍性损坏,自洁式空气过滤器过滤精度低、工作介质不能满足设备工况要求,是导致一级扩压器叶片出现裂纹或前缘边角脱落的主要原因。为此,采取了相应的预防措施。

The diffusers of centrifugal compressors at the Power Plant of Valin Xiangtan Steel were widely broken down. That Low filtering fineness of the self-cleaning air filters and work media could not satisfy operation requirement had been the main cause of cracking in the vanes and falling off of front edge corners of primary diffusers. Therefore, corresponding prevention measures were taken.
