What are the advantages of VSD screw air compressor ?

Nowadays, the use of frequency conversion control for screw air compressors has become the norm, and the frequency conversion control technology has become increasingly mature. The power frequency air compressor uses a standard 50Hz alternating current, the power is fixed, and the relative host speed is also not variable. After using the frequency converter to control, you can achieve frequency conversion, and use frequency modulation to control the speed of the host. Its main functions are as follows:

To

　　Energy saving——Compared with traditionally controlled air compressors, energy saving is the most important and most important thing for inverter-controlled air compressors. The operating state of the supply air compressor can be adjusted according to the compressed air demand.

Stable air pressure——The variable frequency screw air compressor utilizes the characteristics of the stepless speed regulation of the frequency converter, and can start smoothly through the controller or the PID regulator inside the frequency converter. For occasions where the gas consumption fluctuates greatly, the response can be adjusted quickly.

To

　　Operating cost reduction——the operating cost of screw air compressor consists of three items: initial purchase cost, energy cost and maintenance cost. Among them, energy costs and maintenance costs account for the main part of the total cost of air compressors. Through the reduction of energy cost, coupled with the reduction of the impact on the equipment after the frequency conversion start, the maintenance and repair amount will also be reduced, so the operating cost will be greatly reduced.

To

　　Improve control accuracy and prolong service life——The frequency conversion control system has precise pressure control capability, so that the air pressure output of the screw air compressor matches the air volume required by the user's air system. Under the frequency conversion control, the air compressor's exhaust volume will change with the change of the motor speed. Because the accuracy of the frequency conversion control motor speed is improved, it can keep the system pressure change of the pipe network in a stable range, which effectively improves the quality of the working conditions.

  Reduced the noise of the screw air compressor——According to the actual working conditions of the air compressor, after the frequency conversion speed regulation transformation, the motor running speed is significantly slowed down, so the noise during the operation of the air compressor is effectively reduced, and the site is guaranteed The health of the staff.
