Screw air compressor is a kind of air compressor, there are two kinds of single and double screws. The invention of the twin-screw air compressor is more than ten years later than the single-screw air compressor, and the design of the twin-screw air compressor is more reasonable and advanced.
The twin-screw air compressor overcomes the disadvantages of unbalanced and easily damaged bearings of the single-screw air compressor, and has the advantages of long life, low noise, and more energy saving. After the technology matured in the 1980s, its application scope is expanding day by day.
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 keeps rising. The screw air compressor has the advantages of simple structure, small size, no wearing parts, reliable operation, long life, and simple maintenance.
The single-screw air compressor is also called the worm air compressor. The meshing pair of the single-screw air compressor is composed of a 6-head screw and two 11-tooth star wheels. The worm meshes with two star wheels at the same time, even if the force on the worm is balanced, the displacement is doubled. The volume of the air compressor is small, only 9 cubic meters per minute (9m3/min). The weight of the worm air compressor is only piston type. 1/6 of.
