- 1. Extend the service life of the compressor.
VSD air compressor start the compressor from 0HZ, its starting acceleration time can be adjusted, thereby reducing the impact on the electrical and mechanical components of the compressor during starting, enhancing the reliability of the system, and ensuring the service life of the compressor extend. In addition, the frequency conversion control can reduce the current fluctuations when the unit starts. This fluctuating current will affect the power consumption of the grid and other equipment. The frequency converter can effectively reduce the peak value of the starting current to the minimum.
- 2. Save energy.
Compared with traditionally controlled compressors, energy saving is of the most practical significance. The operating conditions of the compressors supplied according to the air volume demand are economical operating conditions.
- 3. Reduce operating costs.
The operating cost of a traditional compressor consists of three items: initial purchase cost, maintenance cost and energy cost. Among them, energy costs account for approximately 77% of compressor operating costs. The energy cost is reduced by 44.3%, coupled with the reduction of the impact on the equipment after the air compressor frequency conversion energy-saving transformation, the maintenance and repair volume will also be reduced, so the operating cost will be greatly reduced.
- 4. mprove the accuracy of pressure control.
The frequency conversion control system has precise pressure control capability. Make the air pressure output of the compressor match 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. Because the accuracy of the frequency conversion control motor speed is improved, it can keep the system pressure change of the pipe network within the range of 3pisg, that is, within the range of 0.2bar, which effectively improves the quality of the working conditions.
- 5. Reduce the noise of the air compressor.
According to the requirements of the compressor's working conditions, after the air compressor's frequency conversion and energy-saving transformation, the motor's running speed is significantly slowed down, so the noise 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.
