What are the advantages of the frequency conversion screw air compressor after the transformation?

Now the frequency conversion technology is progressing, and the maturity of the technology has also transformed the traditional air compressor. So, what are the advantages of the frequency conversion screw air compressor after the transformation?

1. Design principles of frequency conversion transformation scheme of frequency conversion screw air compressor

According to the problems existing in the original working conditions and combined with the production process requirements, the system after the frequency conversion of the air compressor should meet the following requirements:

1. The variable frequency operation of the motor keeps the outlet pressure of the gas tank stable.

 2. The system should have two control loops of frequency conversion and power frequency.

3. The system has two sets of control loops: open-loop and closed-loop.

4. A frequency converter can control two air compressor units, which can be switched by a transfer switch.

5. According to the working conditions of the air compressor, the system should ensure that the motor has a constant torque running characteristic 1.

6. In order to prevent the non-sine wave from interfering with the air compressor controller, the input end of the inverter should have effective measures to suppress electromagnetic interference.

7. In the case of small electricity consumption, when the inverter is running at low frequency, it should be ensured that the temperature of the motor winding and the noise of the motor do not exceed the allowable range.

8. Taking into account the future expansion of the system, the air compressor inverter should meet the requirements of future operating conditions expansion.

Second, the principle of the transformation scheme of the frequency conversion screw air compressor

It is composed of a frequency converter, a pressure transmitter, a motor, and a screw rotor. The pressure closed control system automatically adjusts the motor speed, so that the air pressure in the air storage tank is stable within the set range, and the working process of the air compressor is controlled by constant pressure. . The feedback pressure is compared with the set pressure, and the output step of the inverter is controlled in real time, so as to adjust the motor speed, so that the air pressure in the air storage tank is stable at the set pressure.

3. The benefits of the frequency conversion screw air compressor after the frequency conversion transformation

1. Energy saving

2. Lower operating costs

3. Improve the accuracy of pressure control

4. Extend the service life of the compressor

5. Reduced the noise of the air compressor

With the continuous progress and maturity of frequency conversion technology, it can be gradually incorporated into the transformation of traditional air compressors, so that air compressors will enter the era of real economic operation in the near future and become high-efficiency equipment for enterprises.
