Abstract
A self-suction centrifugal pump consists of a pump body, a motor, an impeller, etc. The utility model is mainly provided with a through hole on the pump body; the through hole is communicated with a chamber body of the pump body and a water outlet end of the pump body; the positions of the water inlet and the water outlet of the pump are higher than the position of the impeller. By adopting the structure, the utility model well solves the problem that the centrifugal pump can not work normally in lower order position water pool, and increases the self-suction function of the centrifugal pump without increment of the cost.
Description
One. technical field
This novel a kind of water pump, particularly a kind of self priming centrifugal pump of relating to.
Two. background technique
In the prior art, water pump has been widely used in every field such as worker, agricultural and life often, and of a great variety, uses water pump not of the same race according to different purposes.But present most of water pump does not possess self-absorption function, often a lot of local ponds all are positioned at lower position, when water pump is positioned at this local work, water pump are used normally, bring a lot of troubles to work, in order to adapt to the demand that this low pool can normally use water pump, people have adopted various ways, the self-priming pump on for example present market, major part all is to add the vacuum water diversion device, or add other water diversion apparatus, cost is increased greatly, and performance is undesirable.
Three. summary of the invention
This novel purpose is: design a kind of self priming centrifugal pump, make the water pump application area more extensive, use convenient.
To achieve these goals, basis is novel structurally to be improved prior art, opens a through hole on the pump housing, makes through hole be communicated with the cavity of the pump housing and the waterexit end of the pump housing; And keep the water outlet of pump and the water inlet position of pump to be higher than the impeller position.
Adopt this kind structure, well solved centrifugal pump cisco unity malfunction problem in low pool, do not increasing under the condition of cost, increased the self-absorption function of centrifugal pump.
Four. description of drawings
This new pump of Fig. 1 body portion sectional view
Five, embodiment
This novel described self priming centrifugal pump is made up of motor (not shown), the pump housing, impeller etc.; Figure 1 shows that the sectional view of this new pump body portion, comprising: the pump housing 1, pump housing cavity 2, impeller 3, waterexit end 4, water intake end 5, water outlet 6, water inlet 7 motor shafts 8, through hole 9, this is novel to be improvement at centrifugal pump in the prior art, make it have self-absorption function, mainly be that the pump housing is improved, specifically: on the pump housing 1, open a through hole 9, make through hole 9 be communicated with the waterexit end 4 of cavity 2 with the pump housing of the pump housing; And keep the water outlet 6 of pump and water inlet 7 positions of pump to be higher than impeller 3 positions.
In the said structure, the impeller 3 of water pump can keep being in the liquid forever, when pump operation, the rotary blade 3 and the waterexit end 4 that are dipped in the liquid make carbonated drink separation by low toward high effect, make water get back to the cavity 2 of pump from pump housing through hole 9, gas in the pump is constantly discharged from the water outlet 6 of water pump, the water inlet of pump is in negative pressure state, in the automatic suction pump of liquid, thereby reaches the purpose of self-priming.
Basis is novel can also to have through hole on pump housing waterexit end, at the cavity by the pipe connecting through hole and the pump housing, can reach the purpose of self-priming equally.
Claims (2)
1. a self priming centrifugal pump is made up of the pump housing, motor, impeller etc., it is characterized in that: open a through hole on the pump housing, make through hole be communicated with the cavity of the pump housing and the waterexit end of the pump housing; And keep the water outlet of pump and the water inlet position of pump to be higher than the impeller position.
2. a kind of self priming centrifugal pump according to claim 1 is characterized in that: the through hole on the pump housing can directly leave in the waterexit end, by the cavity of the pipe connecting through hole and the pump housing.
