The Energy Saving Effect of PM VSD Screw Air Compressor:

1. The biggest feature of the permanent magnet variable frequency air compressor is energy saving. Generally, the energy-saving effect reaches 8% and above. It mainly depends on the working conditions and the parameters of the inverter. When the gas pressure of the customer is unstable and fluctuates greatly, the energy-saving effect will be better.

2. Stable air pressure Since the variable-frequency screw air compressor utilizes the stepless speed regulation characteristics of the frequency converter, it can be started smoothly through the controller or the PID regulator inside the frequency converter. Quick adjustment response.

3. The shaft transmission efficiency of the host and the motor is 100%, no coupling, no gear, no belt drive. Permanent magnet motors do not require bearings, maintenance, and lubricants, eliminating failure points and reducing maintenance costs. Ordinary asynchronous motors often suffer from bearing wear and lead to coil burning and other faults, and the maintenance cost is high.

4. No shock current at start-up The inverter itself covers the function of soft start, the maximum start-up current is within 2 times of the rated current, and the start-up shock is very small. The power frequency start is generally more than 6 times the rated current. When the capacity of the factory power grid is limited, it will cause the air compressor switch to trip. Not only the impact on the grid, but also the impact on the entire mechanical system is greatly reduced.

5. Variable flow control Ordinary industrial frequency air compressors can only work at one displacement, while permanent magnet variable frequency air compressors can work in a wider range of displacement. According to the actual air consumption, the motor speed is automatically adjusted in real time to control the exhaust volume. How much gas is used to produce as much gas, and the air compressor can be automatically dormant when the gas consumption is low, greatly reducing energy loss.
