Permanent magnet variable frequency air compressor advantages and disadvantages

although the permanent magnet variable frequency air compressor is the hottest product in the air compressor market today, it has become a hot spot in the industry with its energy-saving and efficient characteristics. But it is not to say that it is the best, as the so-called "gold is not perfect, no one is perfect", there can be no perfect product, permanent magnet frequency conversion air compressor also has shortcomings. But the advantages are much greater than the disadvantages, and just meet the needs of the current air compressor users.

Let's take a look at its advantages: ① Significant energy saving: The biggest feature of permanent magnet variable frequency air compressor is energy saving. The general energy-saving effect of permanent magnet variable frequency air compressor reaches more than 30%, mainly depending on the working conditions and frequency converter parameters. When the user's gas pressure is unstable, the greater the fluctuation, the better the energy saving effect. Pressure stability: Because the air compressor uses the stepless speed regulation characteristics of the inverter! Through the PID regulator inside the frequency converter, it can start smoothly and adjust the response quickly when the gas consumption fluctuates greatly. ③Low operating noise: Compared with ordinary air compressors, permanent magnet variable frequency air compressors have low vibration and low noise, and are suitable for more occasions. The start does not impact current: the inverter itself covers the soft start function, the maximum starting current within 2 times of the rated current, starting impact is very small. The power frequency start is generally more than 6 times the rated current, when the factory power grid capacity is limited, it will cause the air compressor switch trip. ⑤ can achieve constant pressure air supply: ordinary power frequency air compressor can only work in a displacement, while the permanent magnet variable frequency air compressor can work in a relatively wide range of displacement. According to the actual gas consumption, the motor speed is automatically adjusted in real time to control the displacement. How much gas is used to produce how much gas, and when the gas consumption is low, the air compressor can be automatically dormant, greatly reducing the loss of energy. Wow, so many advantages.

But the permanent magnet variable frequency air compressor also has shortcomings, let's look:

① Demagnetization risk: The motor used in the permanent magnet variable frequency air compressor is a permanent magnet synchronous motor, and the main disadvantage of this motor is the fear of demagnetization. The magnetic steel determines the demagnetization. If the motor is in a high temperature state for a long time, it is easy to appear Demagnetization.

Maintenance trouble: In addition, compared with the ordinary screw air compressor, the maintenance of the permanent magnet variable frequency air compressor is relatively troublesome. In the process of maintenance of the machine head, the motor must be disassembled before the machine head can be disassembled. Professional tools are also required and professional personnel are required to carry out. The advantages and disadvantages of permanent magnet variable frequency air compressors are that the advantages outweigh the disadvantages, so the market for permanent magnet variable frequency air compressors is so large and there are many customers. Our energy-saving air compressor has added two-stage compression on the basis of permanent magnet frequency conversion technology, which is more energy-saving and more energy-saving. The after-sales service team is strong. We will make up for the shortcomings and give customers the best quality air compressor!
