Abstract

A high-water-level self-absorption device for centrifugal pumps comprises a centrifugal pump, a motor connected with the centrifugal pump and a water tank arranged between the centrifugal pump and a water source; and the lower part of the water tank is communicated with the water inlet of the centrifugal pump, and the upper part of the water tank is communicated with the water source through the water inlet pipe. The self-absorption device has the advantages of simple structure, convenience in operation, low maintenance cost and strong reliability.

Description

Centrifugal pump high water level self-priming apparatus
Technical field
The utility model belongs to a kind of centrifugal pump hydrotechny.
Background technique
Among a lot of industrial and mining enterprise and agricultural irrigation, all can use centrifugal pump, a check valve all must be installed in each centrifugal pump pump intake intake pipe bottom, in case close the water backflow in the intake pipe and centrifugal pump behind the centrifugal pump; In case check valve damages, just must carry out pump priming and could normally draw water, and it is very inconvenient to change check valve; If water level in water pool is too high; Just can't change, so it is in use, very inconvenient.
The model utility content
The utility model provides a kind of centrifugal pump high water level self-priming apparatus in order to solve the problem of shipwreck on the low water level.
Adopt following technological scheme in order to solve the problems of the technologies described above: a kind of centrifugal pump high water level self-priming apparatus; Comprise the motor that centrifugal pump is connected with centrifugal pump; Between centrifugal pump and water source, water tank is set; The water intake of water tank bottom and centrifugal pump is communicated with, and water tank upper is communicated with the water source through intake pipe.
Tank top is provided with the filler, and the place, filler is provided with valve.
The volume of water tank is more than 2 times of intake pipe volume.
The volume of water tank is 2.5 ~ 3.5 times of intake pipe volume.
The utility model adds water when using for the first time, need not add water all the life then, water tank of centrifugal pump serial connection; When closing centrifugal pump, the interior water of pipe refluxes and is stored in the water tank, and next time is when using; Centrifugal pump is extracted the water in the water tank out; Because atmospheric pressure is pressed into the water in the pond in the water tank by water inlet pipe, and it can be evacuated.The utility model is simple in structure, easy to operate, maintenance cost is low, good reliability.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Embodiment
As shown in Figure 1; A kind of centrifugal pump high water level self-priming apparatus comprises the motor 2 that centrifugal pump 1 is connected with centrifugal pump, and water tank 3 is set between centrifugal pump 1 and water source; The water intake 4 of water tank 3 bottoms and centrifugal pump 1 is communicated with; Water tank 3 tops are communicated with the water source through intake pipe 5, and water tank 3 tops are provided with filler 6, and the place, filler is provided with valve.The volume of water tank is 2.5 times of intake pipe volume.
