What is the difference between a frequency conversion air compressor and a traditional air compressor

Now is the era of energy saving, no matter what product you buy, it is energy saving and environmental protection. What kind of air compressor can meet this demand in the air compressor field? Of course it is a frequency conversion air compressor. Below, the air compressor manufacturer will tell you about the 6 differences between frequency conversion air compressors and transmission air compressors.

① Compared with the traditionally controlled air compressor, energy saving is of practical significance. The industrial control of the air compressor supplied according to the air volume demand is an economical operating condition. It saves about 20% of electricity bills, and the invested funds can be recovered in about half a year.

②Reduce operating costs. The price of an air compressor consists of three items: initial purchase cost, maintenance cost and energy cost. The energy cost accounts for about 77% of the operating cost of the air compressor. The energy cost is reduced 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.

③Improve pressure control accuracy. The frequency conversion control system has precise pressure control capability, so that the air pressure output of the air compressor matches the air volume required by the user's air system. The output air volume of the frequency conversion control air 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 ±0.2bar, which effectively improves the quality of the working conditions.

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

⑤The noise of the air compressor is reduced. According to the working conditions of the air compressor, 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 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.
