Hydrogen compressor
Thread Content
Medium-pressure hydrogen centrifugal compressor, 1000 cubic meters per hour, inlet pressure of 1.8 MPa, outlet pressure of 2 MPa
Is it better to choose a centrifugal compressor or a reciprocating compressor? What are their advantages and disadvantages?
What needs to be considered here are flow rate, exhaust pressure, compression ratio, routine maintenance, energy consumption, and initial investment; a reciprocating type should be chosen.

For a unit with a pressure increase of 2 kg, a small machine; a reciprocating pump or a high-speed centrifugal blower can be used. In terms of reliability, high-speed centrifugal pumps are better; in terms of cost, reciprocating pumps are more economical. FYI
Is the pressure difference too low as well? Just get a small booster pump
Entrance 1.8； With an exhaust compression ratio as low as 2.0, you can use a centrifugal type, right?
Centrifugal compressors operate reliably and stably, making them suitable for applications with a low compression ratio. Reciprocating compressors have many vulnerable components and are used in applications with high pressure differences at the inlet and outlet
If possible, it’s better to choose a centrifuge; reciprocating machines require too frequent repairs
Relatively speaking, reciprocating pumps are chosen for low flow rates and high pressures, while rotary pumps are used for high flow rates and low pressures; among rotary pumps, centrifugal pumps are selected when the flow rate is less than 1200 Nm3/h.
