Description
Technical field
The utility model relates to a kind of water pump more particularly to the deflector structures of water pump.
Background technique
Water pump is that impeller is made to generate centrifugal force by electric machine main shaft wheel rotor, promotes liquid from unit fixed on water pump suction to exit movement
Process, liquid from impeller outflow after, enter pump chamber through deflector water conservancy diversion and flow out exit of pump again.And liquid export process is because of stream
Body has certain loss when being converted into and being axially moved from radial centrifugal movement, therefore realizes that correct water conservancy diversion is to improve reliability and efficiency
Core component.Currently, baffle is to be connected by front flow guiding plate with the non-flow-passing surface of flow guiding disc, flow guiding disc has certain thickness, makes
Liquid, which exports to pump chamber to go out to receive certain resistance by exit of pump again, forms loss；And the flow-passing surface of flow guiding disc has liquid export
Outlet, can not be formed with rear deflector and reliably be fully sealed (and after generation deflector axial vibrations, directly influence installation
Mechanical seal sealing reliability and service life on rear deflector), make guiding fluid pump housing inner wall, in radial centrifugal force and
Under reaction force, export interference is formed to flow guiding disc flow-guiding mouth, keeps export not smooth to influence flow and lift enough.
Utility model content
The utility model provides a kind of water pump selection formula flow-guiding structure, the purpose is to solve the disadvantage that the prior art, reduces
Flow loss improves effective discharge and lift, improves water pump service life.
The technical scheme adopted by the utility model to solve the technical problem is as follows:
A kind of water pump selection formula flow-guiding structure, the pump housing, front flow guiding plate, flow guiding disc, rear deflector, electricity including sequential connection
Machine, fixing sleeve is equipped with impeller on motor shaft, and impeller is between front flow guiding plate and rear deflector, it is characterised in that: flow guiding disc
Flow-passing surface is equipped with the baffle of several protrusions, and baffle has the side of arc, shape between the side of the arc of adjacent guide body
The honeycomb duct of camber.
It is equipped with card slot towards the face of front flow guiding plate on baffle, front flow guiding plate is equipped with the fixture block towards baffle, above-mentioned
Fixture block is fastened in card slot.
The mating surface of flow guiding disc and rear deflector is equipped with O-ring slot and is embedded O-ring in O-ring slot, after O-ring contact
Deflector.
The utility model has the beneficial effect that
1: twisted shape honeycomb duct is arranged in the flow-passing surface flow-passing surface of flow guiding disc, and liquid is made to export the generation that do not liquidate with pump housing inner wall
Friction, to improve effective discharge and lift.
2: the non-flow-passing surface of flow guiding disc namely "O"-ring slot being set with the mating surface of rear deflector and is equipped with O-ring, make to lead
Flow table is fully sealed with the realization of rear deflector, because being axial soft seal between O-ring and rear deflector, makes to be mounted on rear deflector
On mechanical seal can reduce vibration and improve service life.
3: card slot is arranged in flow guiding disc, cooperates with front flow guiding plate, move radially flow guiding disc will not.It is not easy after fixing in this way
It is moved because being hit pressure, improves certain service life.
Detailed description of the invention
The present invention will be further described with reference to the accompanying drawings and examples.
Fig. 1 is the utility model stereogram exploded view；
Fig. 2 is the utility model combination section；
Fig. 3 is the utility model front flow guiding plate side view；
Fig. 4 is the utility model flow guiding disc side view；
Fig. 5 is the utility model flow guiding disc perspective view.
Specific embodiment
In order to illustrate more clearly of the technical solution of the utility model, attached drawing needed in description will be made below
Simply introduce, it should be apparent that, the drawings in the following description are merely some embodiments of the present invention, for this field
For those of ordinary skill, without creative efforts, it can also be obtained according to these attached drawings other implementations
Example.
As shown in Figure 1 and Figure 2, the main structure of the water pump of the utility model includes the pump housing 1 being linked in sequence, front flow guiding plate
2, flow guiding disc 3, rear deflector 8, motor 9, are equipped with impeller 6 with 5 fixing sleeve of nut on motor shaft, and impeller 6 is located at 2 He of front flow guiding plate
Afterwards between deflector 8, mechanical seal 7 is equipped between motor shaft and rear deflector 8.
The utility model thes improvement is that:
As shown in Figure 4, Figure 5, it is equipped with the baffle 31 of several protrusions in the circumference side of flow guiding disc 3 namely flow-passing surface, leads
Fluid 31 has the side of arc, and the honeycomb duct 30 of arc is formed between the side of the arc of adjacent guide body 31.Pass through in this way
Arc namely twisted shape honeycomb duct 30 are set, so that liquid export is not liquidated with the inner wall of the pump housing 1 and generates friction, to improve effective
Flow and lift.
As shown in Fig. 2, Fig. 3, Fig. 4, Fig. 5, card slot 32, preceding water conservancy diversion are equipped with towards the face of front flow guiding plate 2 on baffle 31
Plate 2 is equipped with the fixture block 22 towards 31 protrusion of baffle, and above-mentioned fixture block 22 is fastened in card slot 32 after assembling.It is set on flow guiding disc 3
Card slot 32 is set, cooperates with the fixture block 22 of front flow guiding plate 2, move radially flow guiding disc 3 will not.It is not easy after fixing in this way because being rushed
