Product advantages:

1, screw rotor and bearing force is small, reduce the pressure load of the host, can choose the material is economical, cost saving, improve the service life.

2, low pressure difference, reduce the internal leakage of the twin screw, improve the volume efficiency and production efficiency.

Two-stage compression screw air compressor has the above two advantages, the same power than ordinary screw air compressor gas production 10%~20% more, the same gas production than ordinary screw air compressor can save electricity 15%.

Air compressor is a general-purpose equipment, which is widely used in iron and steel, electric power, metallurgy, shipbuilding, textile, electronics, chemical industry and petroleum

Mining, light industry, machinery manufacturing, papermaking and printing, transportation facilities, food, casting and spraying, science and technology, automobile maintenance
Two-stage screw compressor (working principle)：

Two stage compression screw air compressor to two sets of screw combination within a single head, direct drive motor through two stage gear linkage, external compressed natural gas by level, to produce high temperature and mixture of oil and gas, after the middle cooling channel, contact with a large number of spray mist cooling, reduce the temperature, again into the secondary compression, the production of a high pressure air compressor. The screw air compressor on the market generally has only one level of compression, a group of Yin and Yang screw. Two-stage compressor can be driven by a motor, or by two motors.
