What is permanent magnet frequency converter screw air compressor

Permanent magnet frequency converter screw air compressor is an advanced air compressor that combines permanent magnet motor technology and variable frequency speed regulation technology. The following is a detailed explanation of the permanent magnet frequency conversion screw air compressor:

Basic definition

Permanent magnet frequency conversion screw air compressor is based on a screw compression mechanism and rotates in the cylinder through two mutually engaging screws to compress the gas. Among them, as the driving source, the permanent magnet motor has the characteristics of high efficiency and energy saving, and can significantly improve the operating efficiency of the air compressor. The frequency conversion speed regulation technology allows the air compressor to adjust the speed and output power according to actual needs, thereby achieving more accurate energy control and energy-saving effects.

Working principle

1. Air compression process:
   • Air passing through the intake valve enters the screw compression chamber. There are two screws that engage each other in the screw compression chamber, and the gas is gradually compressed through their rotation.
2. Permanent magnet synchronous motor drive:
   • Permanent magnet synchronous motor is powered by a power supply to generate a magnetic field. Under the action of the magnetic field, the screw begins to rotate and the compressed air is gradually compressed.
3. Frequency conversion control system:
   • Frequency conversion control system can adjust the speed of the permanent magnet synchronous motor according to the needs of compressed air. By changing the rotation speed of the motor, the amount of air compression can be adjusted, thereby achieving energy saving effect.
4. Cooling system:
   • The air in the screw compression chamber is compressed, heat will be generated. The cooling system cools the air through equipment such as coolers and fans to prevent the machine from overheating.

Main features

1. High efficiency and energy saving:
   • Permanent magnet synchronous motors have high efficiency, high power density and a wide speed regulation range. Combined with frequency conversion technology, the motor’s operating speed can be adjusted according to actual needs to achieve energy-saving operation of the air compressor. Compared with the power frequency screw air compressor, the permanent magnet frequency converter has significant energy saving effect.
2. Pneumatic pressure stability:
   • Permanent magnet frequency converter screw air compressor can maintain a stable output pressure when the load fluctuates, ensuring the stability and reliability of the production process.
3. Still running:
   • Permanent magnet synchronous motor runs smoother, reducing noiseand vibration, providing a quieter and more comfortable working environment for the production workshop.
4. High reliability:
   • Use advanced permanent magnet materials and frequency conversion control technology to improve the reliability and stability of the air compressor, reduce the failure rate, and reduce the downtime loss.
5. Intelligent control: Some high-end models of permanent magnet frequency converter screw air compressors are equipped with intelligent control systems, which can monitor and adjust the quality, temperature, humidity and other parameters of compressed air to ensure the stability and reliability of the production process.
6. Remote monitoring and maintenance:
   • Under combination with Internet technology, remote monitoring and maintenance functions are realized. Users can check the operating status, fault alarm and other information of the air compressor anytime and anywhere through smart devices such as mobile phones, and promptly carry out remote maintenance and troubleshooting, which greatly improves the maintenance efficiency and convenience of the equipment.
