摘要/Abstract

摘要：

中石油独山子石化分公司乙烯厂空压站TAE-100A/30型离心式压缩机主要为化工老区提供清焦风，在运行中该压缩机出现二级联锁停车，联锁复位后再次开机失败。针对该压缩机联锁停机的原因进行了分析，并对机组一级、二级和三级缸进行了解体检修。失效主要原因是压缩机长期运行叶轮疲劳断裂，通过制定防范措施，确保压缩机组的长周期运行。

Abstract:

The TAE-100A/30 centrifugal compressor of the air compressor station in the Ethylene Plant of PetroChina Dushanzi Petrochemical Company is mainly used to provide coke cleaning air for the old chemical plant area. During operation, the compressor experienced a secondary interlock shutdown and failed to start up again after interlock reset. The causes of the interlock shutdown of the compressor were analyzed, and the primary, secondary and tertiary cylinders of the compressor unit were repaired. The main cause of the failure was the fatigue fracture of impeller during the long-term operation of compressor. Some preventive measures were developed to ensure the long-term operation of the compressor unit.

Key words: coke cleaning air compressor, interlock shutdown, wear and scaling
