Qiangsheng 4M80-23.34/23.5-139 fresh-hydrogen compressor · Zhejiang Qiangsheng
Datasheet
Product overview
Power: Selected driver/input required · Pressure: 2.35 → 13.9 MPaG example · Flow: 23.34 m³/min at inlet conditions
The official page identifies 4M80-23.34/23.5-139 as a fresh-hydrogen compressor and associates the example with CNOOC Ningbo Daxie. Its stated duty is 23.34 m³/min at inlet conditions, 2.35 MPa(G) suction and 13.9 MPa(G) discharge. The page lists 800 kN gas force and 630 kN combined piston force. These are different mechanical-force values, not power ratings.
This example must not be combined with the adjacent 4M80-29.23/19.5-171.5 duty or the separate recycle-hydrogen model. The full model string is an identifier; pressure values here come from the explicit parameter text. Motor power, stages, speed, cooling demand and package dimensions are not supplied on this example page.
Give hydrogen analysis, source-pressure/temperature envelope and the receiving process's required pressure and flow cases. The stated flow is inlet volume, not Nm³/min. A comparison using normal volume requires the gas and reference conversion basis, not a changed unit label.
Request the offered cylinder/stage configuration, gas-duty calculation, absorbed/driver input, regulation and operating limits. Agree contamination, seals/vent recovery, pulsation treatment, lubrication and cooling, instruments/protections and installation interfaces. Obtain the P&ID, actual foundation/nozzle loads, service clearances and agreed performance/mechanical/tightness tests. Define commissioning, destination documentation and critical-spares/warranty terms. The original photograph is the illustration on this exact official model page; it is not proof of your ordered package or customer acceptance.
