Compressor generally refers to an air compressor, that is, an air compressor. An air compressor is a device that compresses gas. An air compressor is similar to a water pump in structure. Most air compressors are reciprocating piston, rotating vane or rotating screw. So, do you know where the importance of compressor impeller machining is highlighted? Next, let’s find out more with the editor!

Compressors are divided into two types: piston type and screw type. It is generally composed of shell, motor, cylinder, piston, control device (starter, thermal protection device), cooling system, etc. Refrigeration methods are divided into oil cooling and natural cooling.

Ordinary household refrigerators and air-conditioning compressors use single-phase AC power supply, and their structural principles are basically the same. Both refrigerants are different. According to its principle, compressors can be divided into positive displacement compressors and speed compressors. Volumetric compressors are divided into reciprocating and rotary compressors; speed compressors are divided into axial flow compressors and centrifugal compressors.

Existing household refrigerators and air-conditioning compressors are all positive displacement types, including reciprocating and rotating. Reciprocating compressors use piston, crank, connecting rod or piston, crank, sliding tube and other mechanisms. Currently, most rotary compressors used for rotation are rolling compressors. Commercial air conditioners mostly use centrifugal, vortex, spiral, etc.
