The single-screw air compressor adopts a single-screw

The single-screw air compressor adopts a single-screw rotor to drive two symmetrically distributed star wheels for rotation. The screw groove and the inner wall of the casing form a closed element volume, so that the gas reaches the required pressure (its only advantage is: manufacturing) Low cost, simple structure, ideal force balance, no clearance volume, etc. The twin-screw air compressor consists of a pair of parallel-distributed, intermeshing rotors.

When working, one rotor rotates clockwise and one counterclockwise rotates. The required pressure gas is generated during the intermeshing process, and the advantages are: high mechanical reliability, excellent dynamic balance, stable operation, strong applicability, and the like.

The single-screw air compressor has no twin-screw maturity, no relevant industry standards and national standards. The machine has the right to explain the fault to the air compressor manufacturer. The twin-screw air compressor must meet the national standards and industry standards GB8542, TB/T6430. The single-screw air compressor meshes with the two star wheels to compress the air through a single screw, and the three directly contact each other, resulting in a serious friction between the star wheel and the rotor. (The material of the single-screw star wheel is a resin material, so the star wheel and the screw 。

When the meshing operation is easy to wear, the resin foam is mixed into the oil of the main machine, and the air compressor is prone to high temperature and shutdown. The use time is not long, the internal leakage of the machine head is large, and the exhaust volume is reduced. The twin-screw is engaged by the male and female rotors, and there is an oil film between the two rotors without direct contact, the friction is small, and the displacement does not change with time.
