Cause Analysis and Solution Measures for Valve Failure of New Hydrogen Compressor
At the beginning of 2021,due to the renovation and upgrading of the large oil refining plant,the required flowrate of the 2D50-19.77/19-82 compressor in the hydrogenation refining unit is no longer sufficient,and needs to be increased from the current 16000 Nm3/h to 18000 Nm3/h.According to the design of this compressor,the rated flowrate can reach 20000 Nm3/h,but after various adjustments,the flowrate still cannot reach the required value,and the service life of the air valve has been significantly shortened,mainly due to the damage of the exhaust valve disc.This not only affects the normal operation of the entire machine,but also affects the efficiency of factory.This paper will introduce how to find and eliminate the cause of the fault in this situation,and how to improve the design of the compressor air valve to achieve better performance.
