HMI-6080 Series Air Compressor Controller

How do you control the air flowing through a compressor?

Over the years, compressor manufacturers have developed many different types of control strategies. Controls such as start/stop and load/unload respond to a decrease in air demand by shutting down the compressor or unloading it to increase the compressor discharge pressure so that it no longer delivers air for a period of time. However, each of these methods has its own disadvantages.

Different control methods for different types of compressors

For most compressor systems, air flow is generally controlled by changing the angle of the valve disk. The structure is simple and the response is quick. However, for centrifugal compressors, the performance of the compressor is controlled by adjusting the angle of the guide vanes to change the flow and direction of the air entering the compressor. At present, the most effective method is to control the work through the frequency converter, mainly by adjusting the speed of the motor to control the output flow of the compressor. Changing the operating frequency of the motor can precisely control the air flow and pressure of the compressor. It realizes effective control of the air flowing through the compressor and ensures that the compressor can operate efficiently and stably under various working conditions.
