Description
Technical field
The utility model design water pump field, is specially a kind of guide vane of water pump.
Background technique
The effect of stator is identical with spiral case, is used in multistage segmental type pump.Radial stator and flow channel type guide blade can be divided into by its structural type.Together with the forward stator of flow channel type guide blade is cast with reverse stator, there is a continuous flow path centre, and liquid is flowed in continuous print runner, not easily form dead angle and diffusion suddenly, velocity variations is relatively more even, and hydraulic performance is better, but complex structure, anufacturability is poor.
Stator is in the market ordinary construction, in use, often makes the internal pressure of water pump too low, and then causes water lift of pump to diminish, make the water-outlet quantity of exit of pump discontinuous, uneven simultaneously, and then impact is produced, and even causes water pump to damage.
Model utility content
For the deficiency that prior art exists, it is large that the purpose of this utility model is to provide a kind of lift, continuous, the uniform guide vane of water pump of water outlet.
For achieving the above object, the utility model provides following technological scheme: a kind of guide vane of water pump, comprise stator dish and baffle plate, stator dish is dish shaped in form, the center of stator dish is provided with through hole, the inner circumferential of stator dish is provided with six guide vanes, outside is provided with six pairs of guide plates, the first arc diversion groove is provided with between two guide vanes of arbitrary neighborhood, the degree of depth of the first arc diversion groove deepens to shallow from inside to outside on stator dish, described guide plate comprises the first guide plate and the second guide plate, the second guide plate in the guide plate that the first guide plate in any pair guide plate is adjacent is connected by baffle plate, the second arc diversion groove is provided with between first guide plate and the second guide plate, degree of depth ecto-entad on stator dish of the second arc diversion groove deepens to shallow, described first arc diversion groove is communicated with the second arc diversion groove.
Further, the width of described first arc diversion groove arrives greatly to little from inside to outside on stator dish.
Further, the curved shape of described baffle plate, several baffle plates described are positioned at same circle circumferentially.
Further, the curved shape of the first guide plate, the curved shape of the second guide plate, the arc core of the first guide plate overlaps with the arc core of the second guide plate.
Contrast the deficiencies in the prior art, the beneficial effect that the technological scheme that the utility model provides is brought: the utility model to be deepened with the width of the first arc diversion groove on stator dish from inside to outside to little to large design to shallow on stator dish from inside to outside by the degree of depth of the first arc diversion groove, cause water diminishing gradually in the runner of the first arc diversion groove, make water at the increased pressure entering pump body moment, the hydraulic pressure of pump body is increased, and then make lift become large, simultaneously, the effective anti-sealing of baffle plate stator dish outside occur adverse current phenomenon occur, and then the phenomenon effectively preventing the hydraulic pressure of pump body from reducing occurs, and then prevent lift from diminishing.Several baffle plates are located at same circle circumferentially, improve the sealability outside stator dish, finally when water enters in the second arc diversion groove, in order to reduce the frictional force of water between the first guide plate and the second guide plate, the arc core designing the first guide plate overlaps with the arc core of the second guide plate, and then the phenomenon preventing water from producing excessive resistance and make discharge of pump discontinuous, uneven occurs.
Accompanying drawing explanation
Fig. 1 is schematic top plan view of the present utility model.
Fig. 2 is elevational schematic view of the present utility model.
Embodiment
With reference to Fig. 1-Fig. 2, the utility model is described further.
A kind of guide vane of water pump, comprise stator dish 1 and baffle plate 2, stator dish 1 is dish shaped in form, the center of stator dish 1 is provided with through hole 11, the inner circumferential of stator dish 1 is provided with six guide vanes 12, outside is provided with six pairs of guide plates, the first arc diversion groove 14 is provided with between two guide vanes 12 of arbitrary neighborhood, the degree of depth of the first arc diversion groove 14 deepens to shallow from inside to outside on stator dish 1, described guide plate comprises the first guide plate 131 and the second guide plate 132, the second guide plate 132 in the guide plate that the first guide plate 131 in any pair guide plate is adjacent is connected by baffle plate 2, the second arc diversion groove 15 is provided with between first guide plate 131 and the second guide plate 132, degree of depth ecto-entad on stator dish 1 of the second arc diversion groove 15 deepens to shallow, described first arc diversion groove 14 is communicated with the second arc diversion groove 15.
Further, the width of described first arc diversion groove 14 arrives greatly to little from inside to outside on stator dish 1.
Because the first arc diversion groove 14 is communicated with the second arc diversion groove 15, water is entered by the second arc diversion groove 15, and discharged by the first arc diversion groove 14, because the degree of depth of the first arc diversion groove 14 to deepen with the width of the first arc diversion groove 14 on stator dish 1 from inside to outside to little to large design to shallow from inside to outside on stator dish 1, cause water diminishing gradually in the runner of the first arc diversion groove 14, make water at the increased pressure entering pump body moment, the hydraulic pressure of pump body is increased, and then makes lift become large.
Further, the curved shape of described baffle plate 2, several baffle plates 2 described are positioned at same circle circumferentially.
The effective anti-sealing of baffle plate 2 stator dish 1 outside occur that the phenomenon of adverse current occurs, and then the phenomenon generation effectively preventing the hydraulic pressure of pump body from reducing, and then prevent lift from diminishing.Several baffle plates 2 are located at same circle circumferentially, improve the sealability outside stator dish 1.
Further, the curved shape of the first guide plate 131, the curved shape of the second guide plate 132, the arc core of the first guide plate 131 overlaps with the arc core of the second guide plate 132.
Fluid enters in the second arc diversion groove 15 between the first guide plate 131 and the second guide plate 132, and guide water to enter the pump housing by the second arc diversion groove 15, and then decrease water and enter the pump housing together and the degree producing convection current, make the water pump housing more fast, and then make pump discharge produce continuous, uniform fluid.
When water enters in the second arc diversion groove 15, in order to reduce the frictional force of water between the first guide plate 131 and the second guide plate 132, the arc core designing the first guide plate 131 overlaps with the arc core of the second guide plate 132, and then the phenomenon preventing water from producing excessive resistance and make discharge of pump discontinuous, uneven occurs.
The foregoing is only preferred embodiment of the present utility model, not in order to limit the utility model, those skilled in the art carries out common change and replaces should being included in protection domain of the present utility model within the scope of technical solutions of the utility model.
