Treatment and Cause Analysis of Abnormal Noise in Hydrogen Diaphragm Compressor of a Petrochemical Plant
During the start-up and operation of the hydrogen diaphragm compressor GB821A in a petrochemical plant on March 9,2023,there was an abnormal sound of"dong,dong,dong",which was much louder than normal operation.The sound did not disappear after 20 minutes of operation,so it was arranged to be shut down for maintenance.This article analyzes the abnormal noise of the hydrogen compressor,and analyzes factors such as the tightness of the flywheel and key assembly,the tightness of the connecting rod big head bearing bolt assembly,the plunger rod of the supplementary oil pump,the inlet and outlet one-way valve of the supplementary oil pump,the bottom check valve of the diaphragm head,the overflow valve at the top of the diaphragm head,bearings,crankshafts,connecting rods and other components,and whether they are damaged.The fault diagnosis methods and measures to be taken are gradually investigated in order from shallow to deep and from simple to difficult.It can provide troubleshooting ideas and solutions for similar devices,and has strong guiding significance.
