How to assemble a reciprocating compressor

Abstract

The invention discloses an assembling method of a reciprocating compressor. The reciprocating compressor comprises a stander, a crankshaft, a piston connecting rod assembly and an air cylinder assembly, wherein the air cylinder assembly comprises an air cylinder and an air cylinder bracket. The assembling method comprises the following steps: (S1) assembling the air cylinder into the air cylinder bracket, and assembling a piston of the piston connecting rod assembly into the air cylinder; (S2) connecting a connecting rod of the piston connecting rod assembly with the crankshaft, and assembling the crankshaft to the stander; (S3) controlling the relation motion of the air cylinder assembly between the stander and the piston connecting rod assembly to enable the delivery capacity of the piston relative to the air cylinder to be a preset value; and (S4) welding the air cylinder bracket with the stander. According to the embodiment of the assembling method of the reciprocating compressor, the process is simple, and the gap value between a piston surface and the top surface of the air cylinder after the assembling can be a determined value, so that the number of parts is reduced, and the field management is convenient.

Description

technical field [0001] The present invention relates to the technical field of compressors, and more particularly, to a method for assembling a reciprocating compressor. Background technique [0002] In the related art, a hermetic reciprocating compressor is usually used in refrigeration equipment, which usually includes a crankshaft, a connecting rod, a crankcase, a piston, and a valve group component, wherein the valve group component includes a valve plate gasket, a suction valve plate, and a valve plate. , Cylinder head gasket, cylinder head, cylinder head screws. The valve plate gasket is mainly used to adjust the gap between the suction valve plate and the piston, and its thickness is mainly determined by measuring the gap between the top surface of the cylinder and the piston surface. However, in the related art, it cannot be guaranteed during assembly. After the piston and the cylinder are assembled, the clearance between the top surface of the cylinder and the pist...

Problems solved by technology

The valve plate gasket is mainly used to adjust the gap between the suction valve plate and the piston, and its thickness is mainly determined by measuring the gap between the top surface of the cylinder and the piston surface. However, when assembling in the related art, it cannot be guaranteed After the piston and the cylinder are assembled, the gap between the top surface of the cylinder and the piston surface is a certain value, so that the thickness of the valve plate gasket required is uncertain, for example, the thickness of the valve plate gasket is usually 0.2mm-0.6mm, Therefore, there are often the following disadvantages: 1. There are many types of valve plate gaskets, which is not conducive to on-site management; 2. If the valve plate gaskets are wrong, it is easy to bring quality risks; 3. There are many types of structural parts, which is not conducive to assembly
