Abstract

The invention provides a manufacturing method of a partition plate in a multi-cylinder compressor. The partition plate is located between two adjacent cylinders, and is provided with a through hole Aused for allowing a crank shaft to penetrate through. The partition plate is manufactured of steel through a cutting technology. According to the manufacturing method, the technology is simple and effective, the cost is low, environment protection is achieved, pollution is free, and the integral strength, hardness and dimension precision of the partition plate can be guaranteed. Particularly, whenthe steel is cut by a laser cutting technology, or the steel is cut by a high-pressure water jet cutting technology, the manufacturing efficiency and manufacturing precision can be further improved.

Description

technical field [0001] The invention relates to the technical field of compressors, in particular to a method for manufacturing a partition in a multi-cylinder compressor. Background technique [0002] Rotary refrigeration compressors are widely used in air conditioners such as households because of their high refrigeration efficiency, compact structure, small size, and light weight. [0003] The compression assembly is an important part of the rotary refrigeration compressor, mainly including the cylinder, piston, vane, crankshaft, main bearing and auxiliary bearing. The multi-cylinder compressor includes at least two cylinders, each cylinder has a compression chamber, a partition is arranged between two adjacent cylinders, and a through hole is formed on the partition to allow the crankshaft to pass through. [0004] At present, the separator is generally made by a casting process or a powder metallurgy process. [0005] The casting process is generally a process in whic...
