250hp 185kw Oil Less Electric Screw industrial air compressor silent type Machines Prices

The direct-connected air compressor is a new type of flexible coupling, elastic body, no need to disassemble the machine head, pipeline and valve, the speed of the direct-connected screw air compressor is relatively low, and the life and reliability of the new type of flexible coupling. The shaft is replaced with an elastic body every three years, and there is no other maintenance work. With the new flanged flexible coupling, it is very convenient to replace the elastomer without removing the machine head, piping and valves

 Electric Screw industrial air compressor silent type Working Principle

The screw type twin screw and air compressor are Oil Less Electric Screw industrial air compressors, which are single and double screw. The invention of the Oil Less Electric twin-screw air compressor is more than ten years later than the single-screw air compressor, and the design of the Oil Less Electric twin-screw air compressor is more reasonable and advanced.

The Oil Less Electric twin-screw air compressor overcomes the shortcomings of unbalanced and vulnerable bearings of the single-screw air compressor, and has the advantages of long service life, low noise and more energy saving. After the technology matured in the 1980s, its application range is expanding.

It has become an inevitable trend to replace the piston Oil Less Electric Screw industrial air compressors with more consumable parts and poor reliability with a highly reliable Oil Less Electric Screw industrial air compressors. According to statistics:  screw compressors accounted for only 27% in 1976 and rose to 85% in 1985. In the western countries, the market share of Oil Less Electric Screw industrial air compressors in the developed countries is 80%, and it keeps rising. The Oil Less Electric Screw industrial air compressors has the advantages of simple structure, small volume, no wearing parts, reliable operation, long service life and simple maintenance.

The single-screw air compressor is also called the worm Oil Less Electric Screw industrial air compressors, and the meshing pair of the single-screw air compressor is composed of a 6-head screw and two 11-tooth star wheels. The worm is meshed with two star wheels at the same time, even if the worm is balanced, the displacement is doubled. The volume of the Oil Less Electric Screw industrial air compressors is small, only 9 cubic meters per minute (9m3/min). The weight of the worm Oil Less Electric Screw industrial air compressors is only piston type. 1/6.
