Permanent magnet variable frequency screw air compressors

Application of rare earth permanent magnet motor � Equipped with high efficiency rare earth permanent magnet motor (EPM motor), compared with common frequency modulation host, energy saving performance is better. 22KW full load efficiency of 95%, while the same asynchronous motor efficiency is only 88%, only this one can save 7%. A 22KW can save electricity 6300 degrees / year Application of frequency conversion technology � If the load rate of a 22KW air compressor is 60%, it means that 40% of the time is running in empty load, while the energy consumption of 12.5KW is wasted in empty. If the air compressor is used for 6000 hours in 1 years, the energy consumption of 12.5KW is wasted in 2400 hours, and the use of EPM-22 can save the electric charge 30000 degrees / year air compressor will not work under full load. The average industry statistics load rate was 60%. When there is no load, the motor must continue to run no-load, resulting in waste. Pressure without pressure fluctuation � The 0.8MPA machine of the general machine is actually a no-load pressure of 0.8MPA, and the load pressure is 0.65MPA, which means that 0.65MPA is enough for production. PM85-22 can transfer pressure to 0.65MPA, thereby saving electricity charges by 5850 degrees / year.
