Advantages of fine-numbered permanent magnet variable frequency screw air compressor

2020-11-17 00:00:00

Nowadays, the production technology of air compressors is developing rapidly, and the permanent magnet variable frequency screw air compressors that have emerged are well received by the majority of air compressor users. Popularity naturally has reasons for popularity. The following variable-frequency air compressor manufacturers will take you to see what are the advantages of permanent magnet variable-frequency screw air compressors.

1. Save energy

Compared with ordinary screw air compressors, permanent magnet variable frequency screw air compressors have practical significance in energy saving. Providing air source according to air demand is an economical operation state. It saves more than 20% of electricity costs and can be recycled in about one year. The capital of the frequency conversion part.

2. Reduce operating costs

The operating cost of a traditional compressor consists of three items: initial purchase cost, maintenance cost and energy cost. Among them, energy costs account for approximately 77% of compressor operating costs. The permanent magnet variable frequency screw air compressor reduces the energy cost to 44.3% through variable frequency operation. In addition, after the frequency conversion starts, the impact on the pen is reduced, and the amount of maintenance and repair is also reduced, so the operating cost will be greatly reduced.


3. Improve pressure control accuracy

The frequency conversion control system of the permanent magnet frequency conversion screw air compressor has pressure control capability. Make the air pressure output of the compressor match the air volume required by the user's air system. The output air volume of the inverter controlled compressor changes with the change of the motor speed. Because the accuracy of the frequency conversion control motor speed is improved, it can keep the system pressure change of the pipe network within the range of ±0.01Mpa, which effectively improves the quality of the working conditions.

4. Extend the service life of the compressor

The frequency converter of the permanent magnet variable frequency screw air compressor starts the compressor from OHZ, and its starting acceleration time can be adjusted, thereby reducing the impact on the electrical and mechanical parts of the compressor during starting, enhancing the reliability of the system and making the compression The service life of the machine is extended.

5. Improve the operating efficiency of transformers and power grids

The current fluctuations at the start or loading of ordinary units will affect the power consumption of the power grid and other equipment. The frequency conversion unit of the permanent magnet variable frequency screw air compressor smoothly starts and runs. The peak value of the effective starting current is reduced to the lowest possible level, thereby improving The operating efficiency of the transformer and the grid.

6. Reduce noise and be more environmentally friendly

Under normal working conditions, the motor speed of the permanent magnet variable frequency screw air compressor is only 60% to 70% of the rated speed, which effectively reduces the noise during the operation of the air compressor. Field measurements show that the noise is about 3 to 7 decibels lower than traditional machines.
