Suction Line Sizing
Suction Line Sizing
(OP)
Is there a way to figure out exactly how much compressor BHP will rise if a suction line is under sized? Also, what is the maximum allowable pressure one could have in a suction line?

RE: Suction Line Sizing
RE: Suction Line Sizing
The compressor manufacturer has indeed calculated the temperature rise for the maximum ΔP to which the piston would be exposed.
Since a higher ΔP results in a higher discharge temperature, monitoring it serves to activate a high-discharge temperature trip to prevent overstressing the piston rod.
It is sometimes worth repeating that the high-temperature trip is not meant to protect mechanical components from wear and tear due to high temperatures, but to protect the machine from the consequences of a piston-rod failure.
