Structure of diaphragm compressor

In addition to the body and cylinder, the diaphragm compressor also has piston components, diaphragm groups, air valves, connecting rods and other components. It can be seen that the components of the diaphragm compressor are very fine!

【1】 Piston assembly

The piston assembly of diaphragm compressor is composed of piston, piston ring, piston rod (or piston pin), etc. the piston and cylinder form a compression volume. The reciprocating motion of the piston assembly is transmitted to the diaphragm group through the hydraulic oil in the cylinder

Reciprocating motion to complete the compression cycle of gas in the cylinder.

【2】 Diaphragm group

The diaphragm group of diaphragm compressor is a three-layer structure: two outer diaphragms are barrier layers, and the middle diaphragm provides a discharge path through a fixed 0-shaped seal. At the same time, the cylinder is divided into hydraulic oil chamber and working gas chamber. Diaphragm usually

It is made of rubber, plastic or metal. Most diaphragm compressors use metal diaphragms.

【3】 Air valve

The air valve of diaphragm compressor is used to control the gas suction and discharge cylinder. It opens and closes automatically under the action of pressure difference and spring force, so it is called automatic valve. Air valve is usually composed of valve body, valve plate and spring. The air valve is on the compressor

One of the most important components directly affecting operation, which is divided into inlet (suction) valve and outlet (exhaust) valve.

【4】 Connecting rod

The connecting rod of diaphragm compressor can be divided into split connecting rod and integral connecting rod according to its big end structure
