What is the working principle of screw air compressor?

2026-04-10Views:

We can first look at several different types of screw air compressor host mechanism diagram:

the structure of the single-screw air compressor head is currently applied to the "water-lubricated air compressor" scene by "Shanghai Granklin Group". This series of products have the characteristics of compressed gas without oil and simple maintenance.

100% oil-free air system, the use of "single screw air compressor head" in the application of compressed air is more extensive.

Different products apply different scenarios, and the difference in energy consumption will be relatively large.

The working process of the twin-screw air compressor is divided into four processes: suction, sealing and conveying, compression and exhaust. When the screw rotates in the shell, the screw and the tooth groove of the shell mesh with each other, and air is sucked in from the air inlet and the oil is also sucked in. Due to the rotation of the tooth groove meshing surface, the sucked oil and gas are sealed and transported to the exhaust port; In the process, the tooth groove meshing gap gradually becomes smaller, and the oil and gas are compressed; when the tooth groove meshing surface rotates to the exhaust port of the shell, the higher pressure of the body.
