1、 frequency conversion speed regulation mode
The variable frequency speed regulation is adopted to reduce the shaft power output of air compressor motor.Before the transformation, when the pressure of the air compressor reaches the set pressure, it will automatically unload;After the transformation, the air compressor does not unload, but reduces the gas production of the compressor by reducing the speed, so as to maintain the minimum pressure required by the gas network.Here are two ways to save energy:
1) Reduce the power consumption caused by the sudden change from the unloading state to the loading state of the compressor.
2) The operating frequency of the motor will be reduced to below the power frequency for some time, so that the output power of the motor shaft is reduced.
2、 Centralized control mode
Centralized control mode is adopted for multiple air compressors.According to the use of gas automatically control the number of air compressor operation.Power consumption is saved by automatic shutdown and reduced loading time.
3、Heat energy recovery of air compressor (system renovation)
Heat energy recovery of air compressor is a very environmentally friendly way to save energy.
Working principle of heat energy recovery device: the high temperature oil of the air compressor transfers heat to the cooling water through the heat exchanger, and the cooling water is heated and then flows to the heat preservation bucket, so that the purpose of heat energy recovery can be achieved.
