Description

Compressor cylinder base

Technical Field

The invention relates to the technical field of compressor accessories, in particular to a compressor cylinder base.

Background

As is well known, a compressor (compressor) is a driven fluid machine for delivering and increasing a pressure of a gas, and is a heart of a refrigeration system, which sucks a low-temperature and low-pressure refrigerant gas from a suction pipe, compresses the refrigerant gas by driving a piston through operation of a motor, and discharges the high-temperature and high-pressure refrigerant gas to an exhaust pipe to provide power to a refrigeration cycle, thereby implementing the refrigeration cycle of compression → condensation → expansion → evaporation (heat absorption). The compressor is divided into a piston compressor and a screw compressor, and the piston compressor generally comprises a shell, a motor, a cylinder body, a piston, a control device and a cooling system. The cylinder base is used for fixing the crankshaft and the cylinder body, so that the stability of the cylinder base plays a role in lifting the normal work of the compressor.

Most compressor cylinder bases in the market at present have multiple fixing modes when used, and because the existing fixing modes are single and are all fixed by triangular positioning holes, the stability of the compressor cylinder bases is not ideal, and the structure of the compressor cylinder bases needs to be further improved.

The damping device comprises a fixing seat and damping rods, wherein the fixing seat is respectively installed at the upper end of the bottom plate and the lower end of the middle plate, the damping rods are rotatably connected to the fixing seat through rolling shafts, the damping rods are of two groups of cross structures, and the damping rods are connected in a cross rotating mode through connecting shafts.

The cylinder hole is a cylindrical groove, and the inner wall of the cylindrical groove is of a threaded structure.

And a sealing gasket is arranged on the outer side of the cylinder column, and two sides of the sealing gasket are provided with adhesive layers.

And damping springs are arranged between the cross connections of the damping rods and are symmetrically arranged in two groups.

Compared with the prior art, the invention has the beneficial effects that: the invention has the characteristics of stable structure and good silencing effect, and the column base is provided with the damping telescopic device, thereby reducing vibration and being convenient to install.
