A Brief Introduction To Screw Air Compressors

Screw air compressor is a kind of air compressor, there are two kinds of single and double screws. The invention of twin screw air compressor is more than ten years later than that of single screw air compressor, and the design of twin screw air compressor is more reasonable and advanced.
Twin screw air compressor overcomes the shortcomings of single screw air compressor imbalance and fragile bearings, and has the advantages of long life, low noise and more energy saving. After the maturity of technology in the eighties, its application range is gradually expanding.
It has become an inevitable trend to replace piston air compressors with many wearing parts and poor reliability with screw air compressors with high reliability. According to statistics: Japanese screw compressors accounted for only 27% in 1976, and rose to 85% in 1985. The market share of screw air compressors in western developed countries is 80%, and it maintains an upward momentum. Screw air compressor has the advantages of simple structure, small size, no wearing parts, reliable work, long life and simple maintenance.
Single screw air compressor is also known as worm air compressor, the meshing pair of single screw air compressor is composed of a 6-head screw and 2 11-tooth star wheels. The worm meshes with two star wheels at the same time, even if the worm is balanced by force, the displacement is doubled, and the size of the air compressor is small, only 9 cubic meters (9m3/min) per minute, and the weight of the worm air compressor is only 1/6 of the piston type.
