Screw Compressor pulsations
Screw Compressor pulsations
(OP)
Hello all,
I am trying to measure the dynamic pressure out of a screw compressor (Atlas Copco GA7) with WCT-312 pressure transducer, but I cannot capture any pulsations
I have investigated GA7, and I think that it doesnot contain a muffler or silencer.
Does anyone can help me to know why the pulsations are suppressed
Thank you

RE: Screw Compressor pulsations
In a screw, there is never a shut-off/turn-on (no valves) event so the flow is micro-smooth (there are macro variations, but on a micro basis it is darn smooth).

In screw compressor; the compression mechanism will create pulses in the flow because the lobes from each screw will be forced close together at specific points in the rotational line, which creates
pulses in the compressed gas flow.

What device are you using, a CSI, like a 2130?

The screws certainly can/do scream during operation but I'd expect the outlet pressure to be smooth and pulsation free unlike a recip or a roots type.
