New hydrogen compressor compression ratio
Thread Content
Taking one of the 2D45 new hydrogen compressors installed in the unit as an example, the designed primary compression ratio is 1.52 and the secondary compression ratio is 1.62. However, during actual operation, the suction and discharge pressures of the unit do not reach these designated values; therefore, what is the allowable deviation for the compression ratios at the primary and secondary stages?
Based on the exhaust temperature and the pressure exerted on the liquid separation tank in the outlet pipeline, this compression ratio is merely a reference value
