　　The difference between Kaishan permanent magnet variable frequency screw air compressor and power frequency screw air compressor

　　Once the power frequency screw air compressor with higher energy efficiency deviates from the rated working condition, its efficiency will decrease to varying degrees, and energy-saving air compressors will also become less energy-saving. Kaishan permanent magnet frequency conversion technology can adjust the motor speed according to changes in air consumption, thereby adjusting the exhaust volume, so that the air compressor can maintain high efficiency under any air consumption situation. Therefore, compared with ordinary power frequency screw air compressors, permanent magnet variable frequency screw air compressors have obvious energy-saving advantages when the system air consumption fluctuates, and the greater the fluctuation, the more obvious the energy-saving effect, with a comprehensive energy savings of up to 50%.

　　Comparison table of energy-saving effects

　　Taking the 37kW screw air compressor as an example, based on experimental test results and an average annual operating time of 8000 hours, it is calculated that Kaishan permanent magnet variable frequency screw air compressor is better than ordinary screw air compressor.

　　Annual power savings: 281200-183520=97680 KW.

　　The difference between Kaishan permanent magnet variable frequency screw air compressor and ordinary variable frequency screw air compressor

　　The ordinary screw air compressor can adjust the motor speed through a common external frequency converter, thereby adjusting the exhaust volume, making the gas production and consumption suitable, and achieving energy-saving effects. However, the motors used in ordinary screw air compressors have rated speed, rated power, and rated efficiency. The external frequency converter forcibly forces the air compressor motor to deviate from the rated speed. Once a regular motor deviates from the rated speed, its efficiency will significantly decrease, with the more deviation, the greater the efficiency reduction. The permanent magnet variable frequency screw air compressor using a permanent magnet variable frequency motor can maintain higher motor efficiency at any speed, thus the energy-saving effect is far superior to ordinary screw air compressors with external frequency converters.

　　In addition, the adjustment range of the ordinary screw air compressor with an external frequency converter is 40-100%, which means that when it deviates from the working condition by more than 60%, the external frequency converter will not be able to adjust the motor speed. However, the adjustment range of the Kaishan permanent magnet variable frequency screw air compressor is 20-100%, which means that the Kaishan permanent magnet variable frequency screw air compressor can still work normally when it deviates from the working condition by 80%.

　　Comparison of energy-saving effects of 37kW screw air compressor

　　Annual power consumption of Kaishan permanent magnet variable frequency screw air compressor: 183520kW.

　　Annual power consumption of ordinary screw air compressor: 281200kW.

　　Annual electricity consumption of ordinary permanent magnet variable frequency screw air compressor: 201280kW.

　　Annual power consumption of external frequency converter screw air compressor: 236800kW.

　　Taking the 37kW screw air compressor as an example, based on experimental test results and an average annual operating time of 8000 hours, the Kaishan permanent magnet variable frequency screw air compressor is better than the * * variable frequency screw air compressor.

　　Annual power savings: 236800-183520=53280 kW.

　　Kaishan permanent magnet variable frequency screw air compressor has technical advantages in three aspects: screw host, motor efficiency, and control technology compared to ordinary permanent magnet variable frequency air compressors.
