The frequency conversion of air compressor is to control the input voltage frequency according to the load change, keep the stability of pressure, flow, temperature and other parameters, so as to improve the working performance of air compressor. Air compressor can be more energy-saving from the following four aspects:
(1) The operation cost of traditional air compressor consists of three parts: initial purchase cost, cost maintenance clause: energy. Among them, the cost of energy. The cost accounts for about 77% of the operating cost of the air compressor. The energy cost is reduced by 44.3%. In addition, the impact on the equipment will be reduced after the air compressor frequency conversion energy-saving transformation, and the maintenance and repair quantity will also be reduced, so the operation cost will be greatly reduced.
(2) Reduce the noise of air compressor: according to the working condition requirements of air compressor, after the energy-saving transformation of frequency conversion of air compressor, the running speed of motor is obviously slowed down, so the noise of air compressor is effectively reduced. Frequency conversion technology is a mature energy-saving technology in China. In recent years, with the appearance of synchronous permanent magnet frequency conversion air compressor, it has replaced the original external variable frequency technology, and has obvious advantages compared with ordinary frequency converter.
(3) Improve the accuracy of pressure control - the frequency conversion control system has accurate pressure control ability, so that the air pressure output of the air compressor matches the air volume required by the user's air system. The output gas volume of variable frequency compressor changes with the change of motor speed. Due to the improvement of the accuracy of motor speed control, frequency conversion can keep the system pressure change in the range of 3pisg, i.e. 0.2 bar, which effectively improves the working condition quality.
(4) Prolonging the service life of air compressor frequency conversion energy-saving transformation of air compressor starting air compressor from 0Hz, its starting acceleration time can be adjusted, so as to reduce the impact on the electrical and mechanical parts of the air compressor during starting, enhance the reliability of the system, and prolong the service life of the air compressor. In addition, frequency conversion control can reduce the current fluctuation when the unit starts, which will affect the power consumption of power grid and other equipment. The inverter can effectively reduce the peak value of starting current to a low level.
