Product Structure

Working Principle

A permanent magnet frequency conversion air compressor adopts a pressure sensor to instantly sense the actual use pressure and air consumption in the system, and through the precise control of electric and frequency converter, it changes the motor speed without changing the torque of the air compressor motor, so as to regulate the system pressure in order to realize the output of compressed air according to the demand. When the system air consumption decreases, the amount of compressed air provided by the compressor is larger than the system air consumption, the inverter air compressor reduces the rotational speed, thus decreasing the amount of compressed air output; on the contrary, it raises the motor rotational speed to increase the amount of compressed air in order to maintain a stable system pressure.

Adopting vector control technology, the unit can operate at a wide range of speeds, and at the same time ensure that the motor temperature rise is minimized to get the appropriate and sufficient torque to drive the air compressor smoothly. The motor current consists of the torque component generated by the motor and other vector control technology distributes the current values of the motor to determine the values of the motor current component that generates torque and other current components. Vector control techniques can optimally compensate for this by responding to a voltage drop at the motor end, allowing the motor to output the maximum torque without increasing the current.


Advantages of Permanent Magnet Variable Frequency Screw Air Compressor

High efficiency and energy saving
Frequency conversion regulation can reduce the actual power consumption of frequency conversion compressor in the same proportion, and the energy can be effectively applied to air compression.

Cost Reducing
The energy cost of permanent magnet frequency conversion technology is reduced by more than 35%, and the life cycle cost of compressors can be reduced by an average of 22%. The extra cost of the compressor can be recovered within 1 to 2 years.

Steady Pressure
The PID(proportional, differential, integral) method is used to accurately adjust the exclusive compressor to maintain the stability of the system pressure.

Life Extension
Frequency conversion starts to reduce the impact of meta-collection on the power grid and machinery and prolong the service life.

Top quality
The use of Top-quality imported bearings and the latest research and development of rotor profile, large rotor, large displacement, low speed, low noise, improve efficiency and production quality.
