In the whole process of using permanent magnet variable frequency air compressor, the problem of reducing the exhaust volume is often encountered. In fact, there are many factors that affect the displacement of permanent magnet variable frequency air compressors. Today, Changshengda will show you the following common reasons.

1. Leak

In the whole process of operation, there is no contact between the rotor and the rotor and the casing, and there is a certain gap, which will cause gas leakage. In order to reduce the probability of leakage, sealing teeth can be set on the tooth top of the moving rotor and the rotor is positive The gear teeth are equipped with sealing grooves, and the inner hole is equipped with ring or strip sealing teeth during production and processing.

2. Inhalation

The permanent magnet variable frequency air compressor is a capacity refrigeration compressor, and its suction volume will not change. However, when the suction temperature rises or the suction pressure decreases due to excessive frictional resistance of the suction pipe, the relative density of the gas decreases, which will relatively reduce the quality deviation of the gas.

3. Cooling effect

If the cooling effect is not good, the temperature of the air compressor is prone to rise, which will lead to the problem of reduced exhaust.

4. Rate

The displacement of a permanent magnet variable frequency air compressor is proportional to the speed ratio, but the speed ratio often changes with the working voltage and frequency. When the working voltage or frequency decreases, the speed ratio will decrease, thereby reducing the displacement.

The above points are the factors that affect the displacement of permanent magnet variable frequency air compressors integrated by air compressor manufacturers. I hope to help you. If you have other supplements or questions, please contact our company for your answers.
