It manages, exhaust-valve is equipped with close to the position of evacuation port in the evacuated tube；It is equipped with and is stretched into inside liquid reserve tank at the top of the liquid reserve tank
Liquid level gauge.
In said program, the self-priming apparatus is water sprayer, and the gas access of water sprayer passes through piping connection liquid reserve tank top
Portion.
In said program, it is additionally provided with rinse mouth at the top of the liquid reserve tank, for periodically being cleaned to liquid reserve tank.
In said program, the liquid reserve tank is enclosed housing, using light anticorrosive PVC material.
In said program, the pedestal is equipped with mounting hole, prevents from generating displacement because of vibrations in operation, equipment size can
According to flexible in size adjusting device size and height between user equipment, to meet scene actual use.
Through the above technical solutions, the advantageous effect of the self-priming apparatus provided by the utility model for avoiding centrifugal pump from dallying is such as
Under：

Specific implementation mode
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe.
The utility model provides a kind of self-priming apparatus for avoiding centrifugal pump from dallying, as shown in Figure 1, the device construction party
Just, easy to operate, cheap, significant effect, consistent, service life is long.
As depicted in figs. 1 and 2 avoids the self-priming apparatus that centrifugal pump dallies, and includes the liquid reserve tank 1 being connect with centrifugal pump, storage
Liquid case 1 is enclosed housing, using light anticorrosive PVC material.Liquid reserve tank 1 is fixed on pedestal 6, is additionally provided on pedestal 6 certainly
Device is inhaled, self-priming apparatus is water sprayer 11, and the gas access of water sprayer 11 connects 1 top of liquid reserve tank, water sprayer by pipeline 12
11 included inlet and outlet, it is dynamic by pressure hose, make to form negative pressure in liquid reserve tank 1, to have suction capacity.Pressure
Water only plays the role of driving water sprayer 11, does not enter liquid reserve tank 1, therefore, this partial pressure water can be recycled.
1 top of liquid reserve tank is equipped with inlet tube 2 and overflow port 7, and bottom is equipped with evacuation port 10 and what is connect with centrifugal pump go out liquid
Pipe 3, overflow port 7 and evacuation port 10 are all connected with evacuated tube 9, and exhaust-valve 8 is equipped with close to the position of evacuation port 10 in evacuated tube 9,
It when liquid is excessive in liquid reserve tank 1, can be flowed out by overflow port 7, when needing to emptying rate of liquid in liquid reserve tank 1, can be opened
Evacuation port 10.
