The guide vanes of the guide vane body are provided with the flow spoiler bars having the flow spoiling effect, and therefore formed turbulent flow can be dispersed under the effect of the flow spoiler bars, the turbulent flow is prevented from striking the flow channel wall violently, friction is reduced, the conversion rate of energy is increased, the performance of the water pump is improved, and the water pump can be operated stably.
Description
Technical field
The utility model relates to Submerged Motor Pumps technical field.
Background technique
Pump series products development in recent years is rapid, due to its plurality of advantages such as simple in structure, convenient for installation and maintenance, advanced in performance, the fields such as application and industry, agricultural, mine, urban construction, chemical industry, oil exploration widely, becoming a kind of desirable underground water lift, the instrument of plumbing, is a kind of indispensable universal machine product instrument in the modern life.Stator is that turning of water pump can device, and effect is that impeller is thrown away to the liquid collection coming, and the flow velocity of liquid is reduced, and part kinetic transformation is become to potential energy, by the introducing next stage of uniform liquid, is the important component part of water pump.
In use, along with the running meeting turbulization phenomenon of impeller, liquid is at this moment done irrgular movement to water pump, has perpendicular to the component velocity of runner axial direction and produces, and has many little whirlpools in flow field.When liquid is made turbulent flow, the large flow of resistance is little, and energy loss increases, and these flowing instability phenomenons have caused a lot of harm to the operation of pump.
Existing diffuser throws away impeller the liquid collection coming, and part kinetic transformation is become to potential energy, by the introducing next stage of uniform liquid.In the time having the liquid of turbulent flow to enter diffuser runner, can constantly clash into flow path wall; The liquid rotating in turbulent flow can with flow path wall friction, produce unnecessary energy loss, water pump water conservancy hydraulic performance decline is also unfavorable for the smooth running of water pump simultaneously.
So for the problems referred to above, need now a kind of novel diffuser, can break up the turbulent flow entering in diffuser, reduce energy loss.
Model utility content
The technical problems to be solved in the utility model is to provide a kind of submersible pump guide vanes body with flow-disturbing grid, this diffuser is with the flow-disturbing grid that play flow-disturbing effect, under the effect of flow-disturbing grid, break up the turbulent flow in runner, prevent the shock flow path wall that current are violent, reduce friction, improve energy transformation ratio, improve water pump performance, make water pump smooth running.
For addressing the above problem the technological scheme that the utility model takes be: a kind of submersible pump guide vanes body with flow-disturbing grid is provided with the flow-disturbing grid that are convex structure on the flow-passing surface of every stator of diffuser.
Preferably, described flow-disturbing grid are strip along the water conservancy diversion direction of flow-passing surface and distribute, the rounded or rectangle of the sectional shape of described flow-disturbing grid.
Preferably, be distributed with gully at the surface uniform of flow-disturbing grid.
Preferably, described gully undulate.
The beneficial effect that adopts technique scheme to produce is: 1, should be with the diffuser of flow-disturbing grid, can effectively the turbulent flow that affects pump performance be broken up in diffuser runner, most of liquid keeps the mobile next stage impeller intake place that enters into of monobasic, ensure the smooth flow of liquid, make water pump have the performance of stability and high efficiency, and this turbulence structure does not affect liquid and flows normally in runner, ensure the steady of each grade of water inlet current of water pump, ensure to greatest extent energy conversion efficiency, be potential energy output as much as possible by liquid kinetic transformation.2, the flow-disturbing grid in the utility model are realized the lifting to diffuser function by simple structure.

Embodiment
As shown in Figure 1: a kind of submersible pump guide vanes body with flow-disturbing grid is provided with the flow-disturbing grid 5 that are convex structure on the flow-passing surface 7 of the every stator 2 of diffuser.
As shown in Figures 2 and 3: described flow-disturbing grid 5 are strip along the water conservancy diversion direction of flow-passing surface 7 and distribute, the rounded or rectangle of the sectional shape of described flow-disturbing grid 5, is distributed with gully 6 at the surface uniform of flow-disturbing grid 5, described gully 6 undulates.
Flow-disturbing grid 5 are strip projected parts, along the direction setting of the flow-passing surface 7 of stator 2, length is identical with the length of flow-passing surface 7, the cross section of these flow-disturbing grid 5 can be circle or rectangle, also can be irregular arbitrary shape, it can break up turbulent flow in current in the process of meeting current, and the quantity of flow-disturbing grid 5 can be one or more.Evenly be provided with the gully 6 of undulate at the outer surface of flow-disturbing grid 5, this gully 6 makes the surface of flow-disturbing grid 5 become rough, and current its obstruction effect in impacting is better, is more conducive to break up turbulent flow.
Liquid can form the turbulent flow with whirlpool after impeller throws away in runner, and turbulent flow can be collided with flow path wall, be rubbed, and this can produce unnecessary energy loss, affects the stable operation of water pump simultaneously.Existing stator blade throws away impeller the liquid collection coming, and part kinetic transformation is become to potential energy, by the introducing next stage of uniform liquid.In the time having the liquid of turbulent flow to enter gate vane channel, can constantly clash into flow path wall, the liquid rotating in turbulent flow can with flow path wall friction, produce unnecessary energy loss, pump performance declines, and is also unfavorable for the smooth running of water pump simultaneously.
Flow-disturbing grid 5 are to move towards banded projection of being of setting with the perpendicular direction of stator 2 blade profiles along flow-passing surface 7, this protruding length is identical with the length of flow-passing surface 7, direction is identical with the bearing of trend of flow-passing surface 7, its effect is that the turbulent flow forming in impeller is broken up in the time entering stator 2, the turbulent flow that can effectively hinder flow-disturbing grid 5 in stator 2 continues to form and motion in runner, and the turbulent flow having formed can be cut apart and break up by it after running into flow-disturbing grid 5.Prevent that the turbulent skn friction, the collision flow path wall that in runner, form from producing unnecessary energy loss and affecting the smooth running of water pump.
Shape, position, quantity, size, arrangement on flow-disturbing grid 5 place stator 2 blades of the present utility model can change as required; protection domain of the present utility model is not limited to the description in mode of execution, and any similar variation and equivalence are replaced all within protection domain of the present utility model.
The beneficial effect that adopts technique scheme to produce is: 1, should be with the diffuser of flow-disturbing grid, can effectively the turbulent flow that affects pump performance be broken up in diffuser runner, most of liquid keeps the mobile next stage impeller intake place that enters into of monobasic, ensure the smooth flow of liquid, make water pump have the performance of stability and high efficiency, and this turbulence structure does not affect liquid and flows normally in runner, ensure the steady of each grade of water inlet current of water pump, ensure to greatest extent energy conversion efficiency, be potential energy output as much as possible by liquid kinetic transformation.2, the flow-disturbing grid in the utility model are realized the lifting to diffuser function by simple structure.
