Description

Two-way centrifugal pump
Technical field
The utility model relates to a kind of suction pump, relates in particular to a kind of two-way centrifugal pump.
Background technique
Centrifugal pump utilizes vane rotary and makes water generation centrifugal motion carry out work.Water pump, before startup, must make to be full of water in pump case and suction sleeve, and then starting electrical machinery makes pump shaft impeller and water do high speed rotary motion, and water generation centrifugal motion, is thrown toward impeller outer edge, flows into the setting-out pipeline of water pump through the runner of volute pump case.Impeller is the core of centrifugal pump, and the blade on impeller plays again Main Function, and blade of the prior art is often arcuation, and this just makes impeller to rotate and just can make water generation centrifugal motion to a direction.In addition, the bearing that impeller is rotated tends to damage because of water inlet, and working life is extremely low.
So, be necessary to provide a kind of two-way centrifugal pump, can realize no matter forward is still reversed all can be drawn water, and can improve the working life of bearing, to overcome above-mentioned technological deficiency.
Model utility content
Technical problem to be solved in the utility model is: a kind of two-way centrifugal pump is provided, can realize no matter forward is still reversed all can be drawn water, and can improve the working life of bearing, have one-way rotation and bearing low defect in working life to overcome centrifugal pump in prior art.
For solving the problems of the technologies described above, the technical solution of the utility model is:
A kind of two-way centrifugal pump is provided, comprises: with the pump housing of water intake and water outlet, and bearing support; Described bearing support is connected with the described pump housing by bolt, in described bearing support, be provided with bearing, in the described pump housing, be provided with impeller, one end of described bearing support is connected by main shaft with described impeller, the other end is connected with external driving end by main shaft, and described bearing support also has the cavity flowing out for the water in seal area; Described impeller annular is evenly provided with several prismatic blades, and described impeller is separated into several water dumping mouths wide outside and narrow inside by described several prismatic blades, forms the overcurrent district that can not change with described impeller forward, reversion.
In above-mentioned two-way centrifugal pump, one end that described bearing support connects external driving end is provided with belt pulley.
In above-mentioned two-way centrifugal pump, on described bearing support, be provided with stiffening rib.
In above-mentioned two-way centrifugal pump, described water intake becomes 90 degree to be disposed on the described pump housing with water outlet.
Adopt technique scheme, the beneficial effects of the utility model are: compared with prior art, two-way centrifugal pump of the present utility model, impeller annular is evenly provided with several prismatic blades, impeller is separated into several water dumping mouths wide outside and narrow inside by several prismatic blades, form the overcurrent district that can not change with impeller forward, reversion, realized no matter pump forward is still reversed all can be drawn water, and improved pumping load; In addition, on bearing support, be provided with flowing water cavity, solved the problem that causes water to enter bearing because of mechanical oil seal necrosis, improved the working life of bearing.The utlity model has two-way pumping function, and improved the working life of pumping load and bearing.
Brief description of the drawings
Fig. 1 is the structural representation of the utility model embodiment's two-way centrifugal pump;
Fig. 2 is the structural representation of the impeller of the utility model embodiment's two-way centrifugal pump;
Wherein, 1 is the pump housing, and 2 is bearing support, and 3 is water intake, and 4 is water outlet, and 5 is impeller, and 6 is cavity, and 7 is prismatic blade, and 8 is water dumping mouth, and 9 is belt pulley, and 10 is stiffening rib.
Embodiment
Below in conjunction with drawings and Examples, embodiment of the present utility model is described in further detail.Following examples are used for illustrating the utility model, but can not be used for limiting scope of the present utility model.
Fig. 1 is the structural representation of the utility model embodiment's two-way centrifugal pump; Fig. 2 is the structural representation of the impeller of the utility model embodiment's two-way centrifugal pump.
As depicted in figs. 1 and 2, the utility model embodiment's the two-way centrifugal pump of one, comprise: with the pump housing 1 of water intake 3 and water outlet 4, and bearing support 2,4 one-tenth 90 degree of water intake 3 and water outlet are disposed on the pump housing 1, after the water of generation centrifugal motion has water intake 3 to enter, flow out from water outlet 4.Preferably, this pump housing 1 is roughly circle.
Bearing support 2 is connected with the pump housing 1 by bolt, in bearing support 2, is provided with bearing, is provided with impeller 5 in the pump housing 1, and one end of bearing is in transmission connection by main shaft and impeller 5, and the other end is connected with external driving end by main shaft.Specifically, one end that bearing support 2 connects external driving end is provided with belt pulley 9, by belt pulley 9, external transmission is accessed to bearing and drives to impeller 5, impeller 5 and water do high speed rotary motion, water generation centrifugal motion, be thrown toward impeller 5 outer rims, flow to water outlet 4 through the water intake 3 of the circular pump housing 1.
On bearing support 2, be provided with stiffening rib 10, bearing support 2 also has the cavity 6 flowing out for the water in bearing, the arranging to have solved because mechanical oil seal necrosis causes water of cavity 6 enters the problem of bearing, because the water in inflow bearing can be thrown out of from cavity 6 under the effect of centrifugal force, and then has improved the working life of bearing.
It is worth mentioning that, impeller 5 annulars of the present utility model are evenly provided with several prismatic blades 7, impeller 5 is separated into several water dumping mouths 8 wide outside and narrow inside by several prismatic blades 7, form the overcurrent district that can not change with impeller 5 forwards, reversion, realize the function of this centrifugal pump Double-directional rotary, because no matter impeller 5 forwards are still reversed, the shape of the water dumping mouth 8 that prismatic blade 7 forms can not change, the problem that there will not be like this workman to misapply, make the use of this centrifugal pump very simple, practical.
