Advantages of frequency conversion energy saving transformation of air compressor

1. Compared with the compressor controlled by the energy-saving frequency converter, energy saving is the most practical. The industrial control of the compressor supplied according to the air volume demand is an economical operating condition. Save about 20% of electricity bills and recover the invested funds in about half a year.

　　2. Lower operating costs. The operating cost of a traditional compressor consists of three items: initial purchase cost, maintenance cost and energy cost. The energy cost accounts for about 77% of the compressor operating cost. By reducing the energy cost by 44, 3%, coupled with the reduction of the impact on the equipment after the frequency conversion start, the maintenance and repair volume will also be reduced, so the operating cost will be greatly reduced.

　　3. Improve the pressure control accuracy. The frequency conversion control system has precise pressure control ability, so that the air pressure output of the compressor matches the air volume required by the user's air system. The output air volume of the inverter controlled compressor changes with the change of the motor speed. As the accuracy of the frequency conversion control motor speed is improved, it can keep the system pressure change of the pipe network within ±0, 2bar, effectively improving the quality of the working conditions.

　　 4. Extend the service life of the compressor. The frequency converter starts the compressor from 0Hz, and its starting acceleration time can be adjusted, thereby reducing the impact on the electrical and mechanical components of the compressor when starting, enhancing the reliability of the system and extending the service life of the compressor.

　　 5. Reduced the noise of the air compressor. According to the requirements of the compressor's working conditions, after the transformation of frequency conversion speed regulation, the motor running speed is obviously slowed down, so the noise during the operation of the air compressor is effectively reduced. Field measurements show that the noise is reduced by about 3 to 7 decibels compared with the original system.

　　6. ​​In addition, the frequency conversion control can reduce the current fluctuation when the unit starts. This fluctuating current will affect the power consumption of the grid and other equipment, and the inverter can effectively reduce the peak value of the starting current to the minimum.
