Abstract

The invention discloses a pulse sound attenuation device for a screw rod type refrigerating machine. The pulse sound attenuation device for the screw rod type refrigerating machine comprises a hollow cylindrical sound attenuation cylinder body, and the two ends of the sound attenuation cylinder body are each provided with an annular connecting clamping ring; an annular positioning clamping ring is arranged on the outer wall of the sound attenuation cylinder body; and a sound attenuation tile strip array composed of C-shaped sound attenuation tile strips is circumferentially arranged on the inner wall of the sound attenuation cylinder body. The pulse sound attenuation device for the screw rod type refrigerating machine has the advantages that in the use process, a user enables the connecting clamping rings to be connected with an exhaust opening of a compressor of the refrigerating machine, when pulse exhaust of the screw rod compressor passes through the sound attenuation cylinder body, due to the flow guide effect of the sound attenuation tile strips, the exhaust pulse pressure of the compressor is greatly reduced, and therefore the exhaust noise of the screw rod compressor is greatly reduced, and the performance of the screw rod type refrigerating machine is effectively improved.

Description

technical field [0001] The invention relates to a refrigeration device, more precisely, a pulsation silencer for a screw refrigerator. Background technique [0002] The screw refrigerator is a common industrial refrigeration equipment. The refrigerant is squeezed through the mutual cooperation of the male and female rotors. Therefore, the pulsating exhaust of this refrigerator is likely to cause great noise and affect the performance of the refrigerator. Contents of the invention [0003] The invention mainly solves the technical problems existing in the prior art, so as to provide a pulsation silencer for a screw refrigerator. [0004] Above-mentioned technical problem of the present invention is mainly solved by following technical scheme: [0005] A pulsation muffler for a screw refrigerator, the pulsation muffler for a screw refrigerator includes a hollow cylindrical muffler body, two ends of the muffler body are respectively provided with a An annular connecting sn...
