Abstract

The invention discloses an air suction silencer with a conical air suction pipeline structure. The silencer comprises a silencer box, a partition plate and a silencer cover, wherein an air inlet pipeline is arranged on the silencer box, an inner inserting pipeline is arranged on the partition plate, an air outlet pipeline is arranged on the silencer cover, the air inlet pipeline, the inner inserting pipeline and the air outlet pipeline form an air suction pipeline of an air suction silencer, inner pipes of the air inlet pipeline, the inner inserting pipeline and the air outlet pipeline are allconical, and according to the inner pipes of the air inlet pipeline, the inner inserting pipeline and the air outlet pipeline, the pipe diameters of inlet ends are larger than the pipe diameters of outlet ends. According to the silencer, a flow channel structure is further improved, so that the air transmitting capacity of the air suction silencer is well improved, the flow loss of the silencer is reduced, the air suction mass flow is increased, and the refrigerating capacity and the complete machine energy efficiency ratio of a compressor are improved; and meanwhile, the flow loss and the transmission loss of the air suction silencer can be effectively balanced by adjusting the expansion ratio, so that noise of the compressor is reduced, and the comprehensive performance is optimized.

Description

technical field [0001] The invention relates to the technical field of compressors, in particular to a suction muffler with a tapered suction pipeline structure applied to a reciprocating piston compressor. Background technique [0002] The suction muffler is a key component that affects the energy efficiency ratio and noise of the compressor. During the suction process of the compressor, the refrigerant gas enters the suction orifice of the valve plate through the suction muffler, and then enters the cylinder. When the refrigerant gas passes through the internal pipeline of the suction muffler, there will be a problem of insufficient gas delivery, which will affect the mass flow during the suction process, thereby affecting the cooling capacity, and ultimately affecting the energy efficiency ratio of the compressor. Therefore, in order to increase the air delivery capacity of the suction muffler and reduce the flow loss of refrigerant gas in the internal pipeline of the su...
