Simulation analysis of the influence of f-type suction pipe on the high-frequency performance of rotary compressor
To clarify the changing trend of compressor performance after the removal of the accumulator in the twin cylinder large rotor compressor,the original accumulator of the compressor was replaced with an F-type suction pipe for performance testing.Through experiments,it was found that the high-frequency performance deteriorated significantly when the F-type suction pipe replaced the original liquid reservoir.Therefore,focuses on studying the impact of the F-type suction pipe on the high-frequency performance of the compressor.Uses CFD simulation technology to discover that the main reason for the deterioration of high-frequency performance after replacing the reservoir with an F-type suction pipe is that the F-type suction pipe does not have the phenomenon of suction acceleration inside the original reservoir,and there is a phenomenon of gas reflux inside the pipe.At the same time,it was found that the diameter and length of the F-type suction pipe cannot alleviate the attenuation of high-frequency capability,but the purpose of alleviating high-frequency capability attenuation can be achieved by using a tapered pipe form to increase the suction flow rate or reduce the loss along the inside of the pipe.
