It is provided with second pressure sensor, the pump case to be additionally provided with and is passed with the vibrating sensor, noise transducer, first pressure
Sensor and the controller of second pressure sensor connection.
Further, liquid level gauge is provided with the pump case lateral wall, the liquid level is calculated as glass-tube liquid level meter, its one end
Connected with pump case bottom, the other end at the top of pump case with connecting.
Further, liquid level gauge is provided with the top of the inside pump casing, the liquid level is calculated as liquid level sensor, the liquid
Level sensor is connected with controller.
Further, the motor is the variable-frequency motor being connected with controller.
The beneficial effects of the utility model are：Filling pump situation can be observed by liquid level gauge, it is ensured that the normal of water pump is opened
