Air compressors are widely used in industry and are even called the "life source" of industrial product production. However, there are many types of air compressors. The most widely used one is the screw air compressor.

Screw air compressors are oil-injected single-stage twin-screw compressors, which are divided into single-screw air compressors and twin-screw air compressors. They use high-efficiency pulley transmission to drive the main engine to compress the air. The compressed air in the main engine is cooled by oil injection. The air and oil mixed gas discharged by the main engine is separated by coarse and fine separation to separate the oil in the compressed air, and finally obtain clean compressed air.

The single-screw air compressor consists of a cylindrical screw and two symmetrically arranged plane star wheels, which form a meshing pair and are installed in the casing. The screw has 6 screw grooves and the star wheel has 11 teeth, which is equivalent to 6 cylinders. When the two star wheels and the screw grooves are meshed with each other, each rotation of the screw is equivalent to the operation of 12 cylinders.

Single-screw air compressors also have many advantages: 1. High efficiency and energy saving

2. Reasonable structure, with relatively good force balance

3. Low noise and low vibration

4. Safe operation device

5. High reliability

6. Long life, the life of the bearing can reach 100,000 hours.

The core component of the twin-screw air compressor is the compressor host, which is a type of positive displacement compressor. The air compression is achieved by the volume change of the tooth grooves of the yin and yang rotors that are parallel and meshed with each other in the casing. The rotor pair rotates in the casing that is precisely matched with it, so that the gas between the rotor teeth and grooves continuously produces periodic volume changes and is pushed from the suction side to the discharge side along the rotor axis to complete the three working processes of suction, compression, and exhaust. Therefore, the profile technology of the twin-screw rotor determines the grade of the screw air compressor product positioning.

It has excellent reliability, light weight, low vibration, low noise, easy operation, few wearing parts, and high operating efficiency. Its biggest advantages are.

Nowadays, the leading manufacturers of screw air compressors are basically foreign brands, such as Copco Atlas, Ingersoll-Rand, SULLAIR, etc. Some domestic brands are also gradually rising.
