An overview of the energy saving of air compressors

For an overview of the energy saving of air compressors, this article begins with an overview of the waste of electricity in traditional air compressors, and then summarizes the measures to save energy in air compressors.

Electric energy waste of traditional air compressors:

1. The displacement of the air compressor adopts the capacity adjustment method, so that no matter how the load is reduced, the compressor motor is always in the rated working state, resulting in energy waste;

2. In order to meet the gas requirements of production equipment, traditional air compressors use pressure control. That is, when the higher pressure set by the system is reached, the air compressor is unloaded, and the compressor is in light load operation (the power consumption is 30%-60% of the rated power); at this time, the air compressor is still in a state of wasting power

3. When the traditional air compressor is working under light load, if the gas pressure of the air storage tank does not change within the specified time, the compressor will stop working. The compressor will start frequently, although the Y-△ step-down start is used, the starting current is still 3-5 times the rated current, which has a greater impact on the power grid and other electrical equipment, and is easy to burn the motor and starting solenoid. switch (MCC), and the service life of the air compressor will also be shortened.

4. Moreover, the air supply of the traditional air compressor is constant, and the air consumption of the user is changed, which will also cause great waste of the power of the air compressor.
