How to save energy for permanent magnet variable frequency air compressor

In today's air compressor market, the majority of manufacturers and users pursue energy saving. For screw air compressors, the energy-saving type can be divided into two types: ordinary frequency conversion series and permanent magnet frequency conversion series. Ordinary frequency conversion is to adjust the motor speed through an external frequency converter to achieve the effect of energy saving. Frequency conversion air compressors are often operated under partial load, and permanent magnet motors can make up for the low energy efficiency of frequency conversion air compressors.

　　 The biggest advantage of permanent magnet variable frequency air compressor is energy saving, generally it can save energy about 10%~30%. The amount of energy saving depends on the actual working condition of the air compressor and the parameter setting of the inverter. The biggest factor is the influence of actual working conditions. When the user's gas consumption situation fluctuates, the energy-saving effect is better. The most direct reflection is the proportion of the time when no load is in the total working time.

　　 Permanent magnet variable frequency air compressor can achieve soft start, low starting current, reduce the impact on electrical components, will not cause damage to electrical equipment, and extend the service life of the motor, host and bearings. The high-efficiency and energy-saving control system can prevent frequent loading and unloading of the air compressor. Various related solenoid valves and pneumatic components have greatly reduced the number of actions, greatly reducing the failure rate and maintenance costs.

The air compressor uses a frequency converter to control the speed of the permanent magnet motor, forming a frequency conversion closed-loop control system to achieve constant pressure air supply, more use and more production, less use and less production, stop when you don’t need it, and soft start when you use it. Useless energy loss. In addition, when the displacement is reduced, the speed of the motor slows down. At this time, the noise of the air compressor is much smaller than the noise when running at full speed.
