Abstract

The invention discloses a piston type refrigerating compressor, which comprises a crankshaft (1), a connecting rod (2), a piston (4) and a cylinder seat (5). The piston (4) is provided with a wear-resistant spray coating (6) made of wear-resistant and high-temperature-resistant materials on the surface matched with the cylinder bore of the cylinder block (5); the body material of the cylinder block (5) and The material of piston (4) is aluminum alloy. Adopting the above technical scheme, adopting new structures such as aluminum cylinder seat and aluminum piston sprayed with Teflon material, can improve the gas transmission coefficient, reduce friction, increase cooling capacity and COP; significantly reduce the weight of the compressor; reduce Compressor noise and vibration, to save energy and raw materials, reduce noise.

Description

technical field [0001] The invention belongs to the technical field of refrigeration compressors, in particular, the invention relates to a piston refrigeration compressor. Background technique [0002] At present, the technology commonly used in the refrigerator compressor industry is: the compressor drives the crankshaft of the compressor to rotate through the motor rotation, and the eccentric rotation of the crankshaft is converted into the reciprocating movement of the small head of the connecting rod. The connecting rod drives the piston, and the piston is in the cylinder hole of the cylinder block. For reciprocating motion. [0003] Such as Figure 1 to Figure 5 Shown is a schematic diagram of a refrigeration compressor in the prior art. in, figure 1 is a schematic diagram of the shape; figure 2 is a sectional view of the compressor cylinder block 5; image 3 , Figure 4 is a schematic diagram of a conventional piston 4, Figure 5 It is an assembly drawing of c...
