Problems solved by technology

[0002] The six parts of the pump body of the existing rotary compressor use solid castings, which are heavy, high in cost, and have large rough machining chip allowances; secondly, the physical properties of the castings are not only good in wear resistance, but the other indicators are elastic modulus. The volume and tensile strength are low, which reduces the performance of the pump body

Abstract

The invention discloses a pump of a compressor and the compressor with the pump. The pump comprises an air cylinder, two bearings, a crankshaft, a piston and a sliding sheet. The air cylinder comprises a body part and an extension part which are independent machined pieces. The two bearings are arranged on the two sides of the air cylinder correspondingly, and at least one bearing is a spinning piece. The crankshaft comprises a spindle and an eccentric part arranged on the spindle. An upper anti-thrust piece is arranged on the top of the eccentric part, and a lower anti-thrust piece is arranged at the bottom of the eccentric part. The spindle and the eccentric part are both steel tubes. The piston is of a hollow structure and is a steel structure piece. The sliding sheet is a steel structure piece. According to the pump, the cost of the pump and the machining expense of parts can be reduced to a great extent, the wall thickness of the parts of the pump can be reduced to a proper extent, and the weight of the pump can be lowered; and due to the steel structure, the rigidity of the pump and the assembly clearance of the pump can be improved, and the performance of the compressor can be improved advantageously.

Description

technical field [0001] The invention relates to the field of compressors, in particular to a pump body of a compressor and a compressor having the same. Background technique [0002] The six parts of the pump body of the existing rotary compressor use solid castings, which are heavy, high in cost, and have large rough machining chip allowances; secondly, the physical properties of the castings are not only good in wear resistance, but the other indicators are elastic modulus. The weight and tensile strength are low, which reduces the performance of the pump body. Contents of the invention [0003] The present invention aims to solve one of the technical problems in the related art at least to a certain extent. [0004] For this reason, the present invention proposes a pump body of a compressor, which can greatly reduce the cost of the pump body, appropriately reduce the wall thickness of the parts of the pump body, reduce the weight of the pump body, and the steel structu...
