Abstract

The invention discloses an efficient low-noise reciprocating piston type refrigerator compressor. The efficient low-noise reciprocating piston type refrigerator compressor comprises an air suction valve slice, an exhaust valve slice and a valve plate, wherein the compressor operates back and forth in the manner that a motor drives a crankshaft and the crankshaft drives a piston, and a coating is arranged on the surface of either the air suction valve slice or the exhaust valve slice; or the surfaces of the air suction valve slice and the exhaust valve slice are respectively provided with a coating; the coatings are made of polytetrafluoroethylene or PEEK engineering plastics. In addition, the invention further relates to the manufacturing process of the refrigerator compressor. By means of the technical scheme, the noise of the valve slices of the compressor is largely lowered, fatigue strength is improved, the gas transmission coefficient of the compressor is increased, and therefore the refrigerating capacity is increased. The effect of eliminating the exhaust pulse of the compressor is good, and pressure loss is reduced, so that the gas transmission coefficient is increased. The noise of the compressor is lowered, the energy efficiency ratio of the compressor is improved, and the purposes of saving energy and protecting the environment are achieved.

Description

technical field [0001] The invention belongs to the technical field of refrigeration compressors, and relates to a reciprocating piston refrigerator compressor with high efficiency and low noise. More specifically, the present invention relates to the valve plate and valve plate for the refrigerator compressor. In addition, the present invention also relates to the manufacturing process of the refrigerator compressor. Background technique [0002] Among the noise sources of refrigerator compressors, mechanical noise is one of the main noise sources of compressors. [0003] Friction between mechanical kinematic pairs is the relative sliding or rotation of one part on the surface of another part. Since the parts need to ensure a certain assembly gap during the assembly process, and at the same time, the gap is filled with lubricating oil film, so the mechanical noise generated by the relative sliding and rotation of the parts is not high. [0004] In the existing technology...
