Automatic control system of water pump

The invention relates to the technical field of water pumps, in particular to an automatic control system of a water pump. A device comprises the automatic control system of the water pump. The automatic control system comprises a shell. The shell is sequentially provided with a water inflow joint, a hydraulic assembly, a drive mechanism, a controller and a water outflow joint. After water currents enter the water inflow joint, the water currents sequentially pass through the hydraulic assembly, a passageway between a machine seat of the drive mechanism and an outer shell and a passageway between a driver seat of the controller and the outer shell, the power supply end and the controlled end of the drive mechanism are connected with the controller, a pressure sensor is further arranged onthe water outflow joint, and the signal end of the pressure sensor is connected with a corresponding port of the controller. The automatic control system has the beneficial effects that water-cooled heat dissipation is used i
