Can centrifugal air compressor use inverter control?
Understand the principle of centrifugal air compressor
The centrifugal air compressor is a speed type compressor. The impeller drives the gas to rotate at a high speed to generate centrifugal force. Due to the diffusing flow of the gas in the impeller, the flow rate and pressure after the gas passes through the impeller are improved, and the production is continuously performed. Compressed air.
Why can't it be unnecessary?
The frequency conversion control is very effective for the screw compressor. Through the pressure feedback, the frequency conversion adjusts the speed of the speed. The screw type "the change in the rotational speed is independent of the exhaust pressure", while the centrifugal type is "the exhaust pressure changes with the change in the rotational speed". That is, the rotation speed of the centrifuge drops, and the pressure also decreases. Therefore, when a certain degree of pressure is required at the end, the capacity adjustment of the centrifugal compressor cannot be controlled by frequency conversion.
