Abstract
Provided is a water supplementing device for a centrifugal pump station unit. The water supplementing device for the centrifugal pump station unit comprises a water supplementing tank, an electromagnetic valve and a centrifugal pump. The lower portion of the water supplementing tank is connected with a water source through a water inlet pipeline, a one-way valve is installed in the water inlet pipeline, an upper liquid level meter and a lower liquid level meter are arranged on the water supplementing tank, and a one-way valve for exhaust is arranged on the top of the water supplementing tank. One end of the electromagnetic valve is connected with a water storage bin, and the other end of the electromagnetic valve is connected with the water supplementing tank. A water inlet of the centrifugal pump is communicated with the water supplementing tank, and a water outlet of the centrifugal pump is connected with the water storage bin. Opening and closing signals generated by the upper liquid level meter and the lower liquid level meter are used for controlling turn-off and turn-on of the electromagnetic valve respectively. When a water level is lower than the lower liquid level meter, the electromagnetic valve is opened through a control system, water supplementing is carried out on the water supplementing tank through a pump outlet, and in the process of the water supplementing, gases in the water supplementing tank can be discharged through the one-way valve for exhaust. When the water level is higher than the upper liquid level meter, the electromagnetic valve is closed through the control system, and the water supplementing is completed. The water supplementing device for the centrifugal pump station unit is simple in structure, convenient to manufacture, low in manufacturing cost, high in safety and capable of protecting the centrifugal pump against abnormal operation due to water shortage.

Embodiment
The utility model is a kind of water replenishing device for centrifugal pump pumping plant unit, and it comprises:
Replenisher tank, the replenisher tank bottom connects the water source through intake pipe, and one-way valve is housed in the intake pipe, arranges on the replenisher tank to have the level meter at two liquid level control points up and down, and the replenisher tank top is provided with the one-way valve that exhaust is used;
Solenoid valve, the one end connects water storing bin, and an end connects replenisher tank;
Centrifugal pump, its water intake is communicated with replenisher tank, and its water outlet is connected with water storing bin;
The switching signal of two liquid level control point generations is respectively applied to control shutoff and the connection of solenoid valve up and down.
Be described further below in conjunction with accompanying drawing.
As shown in Figure 2.Centrifugal pump pumping plant unit water replenishing device comprises:
Be illustrated in figure 3 as control circuit figure.Among the figure: upward connect power supply after the coil three series connection of level meter 13, following level meter 14, auxiliary reclay AK, it is in parallel with following level meter 14 that often the driving node AK-2 and solenoid valve 2 the two connects power supply after connecting of auxiliary reclay, another of auxiliary reclay are often left node AK-1.Last level meter 13 nodes are normally off when not triggering.It is open mode when the node of following level meter 14 does not trigger.
The utility model water replenishing device can be realized automatic water supplement, and its working principle is as follows:
When water level is lower than level meter 14, the node closure of following level meter 14, auxiliary reclay AK gets electric, and it is often opened node AK-2 closure and opens solenoid valve 2, to replenisher tank 1 interior moisturizing, auxiliary reclay AK often leaves node AK-1 by it and realizes self-insurance simultaneously by pump discharge.Gas during moisturizing in the replenisher tank 1 can be discharged by one-way valve 11.When water level was higher than level meter 13, the node of last level meter 13 was opened, auxiliary reclay AK dead electricity, and it is often opened node AK-2 and opens and close solenoid valve 2, and moisturizing is finished.
Because water replenishing device did not have water in the replenisher tank 1 before using, therefore be provided with the cup 12 of pouring water that communicates with replenisher tank at the top of replenisher tank 1 so that by this cup 12 of pouring water to replenisher tank 1 moisturizing.In the water replenishing device running, this cup 12 of pouring water is just ineffective.
