Why is an interlock for low inlet pressure required for hydrogen compressors?
Thread Content
Why is an interlock for low inlet pressure installed on the Tier 4 piston hydrogen compressor of Delaiselan, with an outlet pressure of 33 MPa? Is this based on process considerations or on equipment protection? If we set aside the process-related reasons, what are the consequences of not installing a low inlet pressure interlock?
A low inlet pressure can cause suction in the pipeline connected to the inlet
To prevent a range of issues such as negative pressure formation, pipeline deformation, container deformation, deformation of gas tanks due to negative pressure, air leakage caused by negative pressure at flanges leading to explosions, and malfunction of pressure sensors
From the compressor’s perspective, the suction pressure is low; to achieve the desired outlet pressure, the compressor’s load increases, the pressure ratio rises, and accordingly the temperature also increases, which is not favorable for the operation of the unit
Do you think a low interlock of 1.2 MPa is reasonable? I don’t think it’s for that reason.
To prevent negative pressure from occurring, high oxygen content in the air entering the front system can lead to explosions, as well as deformation of pipes and containers, and deformation of gas tanks due to negative pressure
A low pressure results in an increased compression ratio; the exhaust temperature is high, and if it’s too low, it will cause the buffer tank to collapse!
Prevent the buffer tank from deflating and protect the compressor pipes
To prevent a range of issues such as negative pressure drawing, pipeline deformation, container deformation, deformation of gas tanks due to negative pressure, air leakage caused by negative pressure at flanges leading to explosions, and malfunction of pressure sensors

Low inlet pressure in the centrifuge can cause surging; low inlet pressure in the reciprocating machine leads to an increase in piston temperature, eventually resulting in shutdown of the equipment. Personal experience
