Increase in air volume of reciprocating compressors
Thread Content
The hydrogenation unit of our company’s new hydrogen compressor (reciprocating compressor) is currently operating at full capacity, with a gas flow rate of 26,000 standard cubic meters. We plan to increase this flow rate to 30,000 standard cubic meters. Do any experts have proven solutions that have been successfully implemented in practice? I beg you :) Compressor parameters: 1) Volumetric flow rate (at suction condition): 23 m3/min 2) Suction pressure: 2.2/4.848 MPa(G) 3) Discharge pressure: 4.848/9.1 MPa(G) 4) Suction temperature: 40/40 ℃ 5) Discharge temperature: 121/105 ℃ 6) Cylinder diameter: Φ430/300 mm 7) Stroke: 315 mm 8) Crankshaft speed: 333 r/min 9) Main shaft diameter: φ360 mm 10) Shaft power: 1650 kW 11) Lubricating oil supply temperature for the moving parts: ≤45 ℃
Expand the cylinder, recalculate shaft power – is it exceeding the motor’s power capacity?
Increase the speed of the reciprocating machine? Stop misleading newcomers
Hehe, the only way is to lower the temperature during the compression process, thereby reducing the pressure at the back. We can only study the process to see if it’s possible to meet your required specifications. It’s better not to think about the other options; there are too many things involved. There are no unmodified versions, and it’s best not to attempt anything without a specific plan. A complete plan is necessary in order to carry out such tasks; one can’t act on whimsical ideas. There have been cases where work stopped halfway, leaving the equipment unusable. It’s better to back down and think of a solution from a technical perspective. For reference.
It is feasible to consider increasing the rotational speed, but an assessment is required; please have the manufacturer conduct such an assessment.
