Screw air compressor is how to load it

Screw air compressor loading methods are mainly the following:

manual loading: First, open the air compressor switch and start the compressor. Set the desired pressure value in the loading pressure gauge, then open the intake valve and adjust the flow of the intake valve to the appropriate position. At this time, the air enters the compressor from the intake valve, compresses through the compression screw, and finally enters the unloading state after reaching the set pressure value.

Automatic loading: This is a control system of the air compressor, which can automatically adjust the intake valve and the outlet valve to control the output of the compressor. By setting the control system, the air compressor can automatically start and stop at the right pressure, and the intake valve flow will automatically adjust to meet the demand.

Electronic control loading: The electronic control system will control the loading according to the system demand and pressure difference. When the system demand increases or the pressure difference is large, the electronic control system will send a signal to increase the load of the compressor and increase the exhaust pressure.

Frequency conversion loading: Some advanced screw compressors use frequency conversion loading technology to control the loading of the compressor by changing the speed of the motor. When the system demand is small, the electronic control system will reduce the motor speed and reduce the load to achieve the effect of energy saving.

Differential pressure loading: In this way, by setting a differential pressure valve, when the system differential pressure exceeds the set value, the valve opens to increase the loading; when the differential pressure decreases, the valve closes to reduce the loading.

In general, there are various loading methods for screw air compressors, and the appropriate loading method can be selected according to actual needs and usage scenarios. These loading methods are designed to ensure that the compressor can operate efficiently and stably under different requirements.
