Intelligent water spray system of water spray type plunger slurry pump

The invention discloses an intelligent water spray system of a water spray type plunger slurry pump. Two clear water flushing pipelines are connected to each spraying system of the pump in parallel and are each connected with a high-pressure clear water pipeline and a low-pressure clear water pipeline through solenoid valves in parallel. A signal transmitter is arranged at the tail end of each plunger of the pump, two signal receivers are arranged on each pump case side by side, and when the plungers are about to enter a slurry discharge high pressure area and slurry discharge is about to be finished, the signal receivers correspond to the signal transmitters up and down. The signal transmitters and the signal receivers are connected with the input end of a PLC control system, the output end of the PLC control system is connected with the control ends of the solenoid valves, the PLC control system is used for controlling the solenoid valves to be connected with the high-pressure clearwater pipeline and the lo
