Does the compressor stop when the air compressor is unloaded?
There are two cases,First: the gas consumption of the pipeline is 0, the pressure in the pipeline is increased, and the exhaust pressure of the air compressor is automatically unloaded when the exhaust pressure rises. Unloading time,Normal operation of air compressor. Only the intake valve is closed, and the inlet valve is a small hole on the butterfly valve (no hole will not close).The oil release valve on the oil separation cylinder opens and is discharged to the intake valve (which is said to be atmospheric), and the pressure of the oil separation cylinder is smaller. Therefore, the minimum pressure valve for the gas supply in the direction of the oil separation cylinder is closed so that the air supply is not backward.Second: you press down, attention is not an emergency stop.Air compressor motor will not immediately power off, but will turn off the intake valve, open the vent valve, usually through about 7S, after the completion of the bleeding stop.Special circumstances, if the emergency state press the "stop" button, the air compressor motor immediately power-off, air release valve to open the bleeding.
These two values, different manufacturers do not have absolute relationship, sure is the loading pressure < calibration work pressure < unloading pressure.
The air compressor in the boot operation state, the pressure sensor unit gas outlet pipe, the detection value reaches the minimum working pressure, the preset value, the air compressor start loading (it begins to compressed air), the preset minimum working pressure, the pressure of air compressor is loaded; similarly, in the loading process of air compressor to be completed when the pressure sensor reaches a preset maximum working pressure, triggering the air compressor unloading (i.e. inlet valve plate to close the stop, the compressed air) preset the maximum working pressure of the air compressor is the unloading pressure.
The compressor does not stop when the compressor is unloaded.
