A kind of multi-stage water pump enclosed pressure flow-guiding structure
Technical field
The utility model relates to water pump technology, specially a kind of multi-stage water pump enclosed forces flow-guiding structure.
Background technique
Centrifugal pump refers to the centrifugal force by generating when impeller rotation to convey the pump of liquid, and centrifugal pump has vertical, horizontal, single
Grade, multistage, single suction, double suction and diversified forms, the vertical centrifugal pump such as self-priming are referred to as submerged pump, fused salt submerged pump.
The water pump in centrifugal water pump field is either single pump or is multistage pump, and the water conservancy diversion between the both stage impellers of multistage pump is logical
Road all in outermost is generally the loop being continuously turned on, water can in this region of pump shell 360 degree rotation, to improving pressure
Unfavorable, hurriedly there is angle un-reasonable phenomenon in the runner staggered floor turning of part water pump stator portion, cannot round and smooth guidance water flow stream
It crosses, it is unfavorable for improving flow and pressure.
Flow-guiding channel in common multistage pump is because there is the channel of staggered floor commutation, so generally sand core casting or evaporative pattern pour
Casting, needs to carry out filling or bonding casting die in advance, has considerable restraint to speed of production is improved, also there is part flow-guiding channel
It is that stainless steel plate is welded, needs to be located in using fixture after first punching press to be welded, both the above all has production efficiency
It is low, facilitation is not had to cost is reduced.
Summary of the invention
In view of the deficiencies of the prior art, the utility model provides a kind of multi-stage water pump enclosed pressure flow-guiding structure, solves
Pressurization is lower, and processing step is more, and speed of production is slow, and production efficiency is low, to reducing the unfavorable problem of cost.
In order to achieve the above object, the utility model is achieved by the following technical programs:A kind of multi-stage water pump enclosed is strong
Flow-guiding structure processed, including pump shell and the guide wheel being sleeved on inside pump shell;The front of the guide wheel is provided with integrated
Force splitter;Shunting crossover port is uniformly provided on the guide wheel and positioned at pressure splitter outer parabola direction;It is described
The inside integrated setting of pump shell has pump shell circular arc flow deflector, and pump shell periphery is uniformly provided with pump group assembly
Screw hole;The center of the pump shell and guide wheel correspondence offers pump shaft hole.
As the further preferred scheme of the utility model, dowel hole is offered on the guide wheel, and pin shaft is through fixed
Position pin hole will be fixed between pump shell circular arc flow deflector and guide wheel.
As the further preferred scheme of the utility model, the pressure splitter is at least provided with 8, and uniform circular
It is distributed on guide wheel.
As the further preferred scheme of the utility model, the back side of the guide wheel is evenly arranged with matches with splitter is forced
The staggered floor water conservancy diversion inclined-plane of conjunction.
As the further preferred scheme of the utility model, the pump shell circular arc flow deflector at least provided with 8, and
It is evenly distributed on the inside of pump shell, and extends to the center of pump shell, until sencond stage impeller water inlet.
Beneficial effect
The utility model provides a kind of multi-stage water pump enclosed pressure flow-guiding structure;Has following beneficial effect:
(1), the multi-stage water pump enclosed force flow-guiding structure, can be used with more than two-stage multi-stage superimposed series winding, the son of link
Mouth is designed as identical size, and radial faying face is equipped with seal groove, and quick assembling and pressure-resistant function may be implemented, and dispatches from the factory in production
Preceding series as needed realizes the combination of different series.
(2), the multi-stage water pump enclosed force flow-guiding structure, after combination constitute force enclosed diversion function, guide wheel centre bit
Placement location water pump vane, the water that impeller rotation is dished out is through forcing splitter to enter shunting crossover port, what is be arranged through the guide wheel back side
Circular arc flow deflector inside staggered floor water conservancy diversion inclined-plane and pump shell forms channel, can be obtained after combination it is round and smooth, slight drag
Staggered floor rotating flow guidance channel, flow-guiding channel guidance water flow staggered floor it is round and smooth rotate into junior's impeller center water inlet, Ke Yiyou
Effect increases the pressure of water pump, and is conducive to improve flow.
(3), the multi-stage water pump enclosed force flow-guiding structure, component is obtained by the quick die casting of anti-corrosion aluminium alloy, unilateral processing
0.5mm is measured, numerically controlled lathe High-speed machining can be used, it is high that production process lack production efficiency, pump closed pressure flow-guiding structure
The flow-guiding channel that production cost is cast with respect to sand core or evaporative pattern is cast and metal plate punching mode produces reduces very much.
