Working principle of single screw air compressor

The air end of air compressor is composed of one cylindrical worm and two symmetrical plane star wheels, which are engaged and mounted in a casting. The worm groove, casting and the tooth surface form a sealed cavity. The worm rotates the star wheels. When the star wheels ove in the worm groove, the air

in the groove is compressed and exhausted. The worm has 6 grooves and is separated horizontally by two star wheels into two working cavities, each of which realizes separate suction, compression and exhaustion. Therefore,one single screw air compressor equals one unit of six double cylinder pistion

compressor.

 

Our products have ISO2000 and CE certification. They are widely used in different types of industries, such as Power Station, steel industry ,mining, steel or textile.

 

Main Features:

1.Rational Structure

The star wheels are paired on both sides of the screw shaft to counteract the radial force acted on the shaft and the axial force on the channel by air. Hence the screw is free from any radial or axial force to achieve the absolute balance status.

 

2.High Efficiency
While running, each screw works twice per rotation so the channel space is fully utilized to achieve more exhaling volume compared with the same structural & dimension air compressor. The screw slot depth of screw decreases with the increase of pressure. When exhaling finishes and the star wheel separate from the screw slot, the depth is zero without any clearance volume, then high volume efficiency is achieved. As apply unloading device and servo automatic air volume adjustment, the energy save effects is significant which as much as more than 60% of lower consumption when running at no load.

 

3.Extended Maintenance Cycle
Free from any radial or axial forces and pressures in the air compression process, the shaft life of the air compressor can be as long as 50,000 hours, overcoming the easy wearability of the bearing and shaft seals of double screw air compressor, extending the maintenance cycle, and its durability exceeds other counterparts.

 

4.High Reliability

The star wheels of air compressor is made from PEEK materials, which has been proved of its high reliability in terms of air quality, energy saving, continual running, and low maintenance etc. over the years.
