China 37kw 50HP Low Pressure Single Screw Air Compressor for Spray Paint

Permanent Magnet Frequency Conversion Screw CompressorTuowei PM Frequency Conversion Screw Compressor saves 10%-15% energy more than variable speed screw compressor, while it saves 30%-40% more than standard screw compressor.High Efficiency PM Motor. With the highperformance permanent magnet material, PM motor won't lose magnetism even under 120ºC and can run for more tha n 15 years. No motor bearing: permanent magnet rotor is installed directly on the stretch out shaft of male rotor. This structure doesn't have the bearing and eliminates the motor bearing fault.Comparing to normal variable speed motor, the permanent magn et synchroous motor performs with even better energy efficiency.Especially in the low-speed condition, it can still maintain a high motor efficiency.Technical data:

Significant energy saving effect
Permanent magnet synchronous variable air compressor is always running in the loaded state, no uninstall run phenomenon, and this no power wastage. Permanent magnet synchronous motor efficiency is very high compared with ordinary motor efficiency by at least 2%, with less power consumption and greater output torque, energy-saving effect is remarkable, fee energy consumption remained at the level of the most economical.
Introduction of permanent magnet synchronizing variable frequency compressor
The permanent magnet synchronizing variable frequency compressor is a most recent compressor with excellent quality and high efficiency and energy saving at present. It is an advanced technique owned by only a few advanced countries and zones in the world. It is a high-end tendency for the future compressor development. The design concept and technical measure has broken through the tradition technical concept. It integrates the most sophisticated and energy saving technical factors.
Strong support of frequency converter to compressor
The permanent magnet synchronizing variable frequency compressor is equipped with special frequency converter with wider frequency converting rang. With the rapid development of techniques, the variable frequency compressor has become a high-grade machine in the energy saving area. It can realize maximum energy saving effect with the permanent magnet synchronizing motor.
