Why the selection of permanent magnet frequency conversion air compressor to reduce the energy loss of air compressor permanent magnet frequency conversion screw machine by frequency conversion speed control technology, the unit can be infinite start and stop, really 0-100% stepless speed change. Can let the compressor exhaust, and the user's gas demand can be perfectly combined [ variable frequency control compressor output gas can change with the motor speed change ] . Compared with ordinary screw air compressor save electricity cost about more than 30% to extend the life of the compressor frequency converter from idle to full load start compressor, its starting acceleration is gradual [ can effectively reduce the starting current peak to a minimum ] . Thus, the impact on the electrical and mechanical components of the compressor during starting is reduced, and the reliability of the system is enhanced. The service life of the compressor is prolonged. The operation cost of traditional compressor is composed of three parts: initial purchase cost, maintenance cost and energy cost, of which energy cost accounts for about 80% of the compressor operation cost. 20% of the maintenance costs and procurement costs are reduced by 30% or more through the frequency conversion energy, plus the frequency conversion after starting the impact on the equipment to reduce the maintenance and maintenance volume, so the operating costs will be greatly reduced. The noise of the air compressor is reduced according to the working condition of the compressor, the motor running speed is obviously slowed down after the frequency conversion speed adjustment reform. Therefore, the noise of the compressor running is effectively reduced. Field measurements show that the noise is reduced by about 3-7 decibels compared with the original system.
