2BV Explosion Proof Vacuum Pump Working Principle

The CX-D series variable frequency constant pressure water-saving irrigation automatic control device, in addition to the multi-stage pressure setting conversion circuit, operates on the same principle as the CX-B series variable frequency constant pressure water supply automatic control device. The multi-stage pressure setting conversion circuit is designed with four pressure levels corresponding to sprinkler irrigation, micro-sprinkler irrigation, drip irrigation, and pipeline irrigation. During irrigation, the PLC outputs the corresponding control signal according to the irrigation method, the pressure setting conversion circuit automatically switches to the corresponding pressure level, and the device supplies water at a constant pressure at this set pressure, achieving water-saving irrigation.
