Description
Technical field
The present invention relates to water pump technology, specially a kind of multi-stage water pump enclosed forces flow-guiding structure.
Background technology
Centrifugal pump refers to the centrifugal force generated when being rotated by impeller 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 leads to
Road is the loop that is continuously turned on generally all in outermost, water can in this region of pump shell 360 degree rotation, to improving pressure
Unfavorable, hurriedly there are angle un-reasonable phenomenons at the runner staggered floor turning of part water pump stator portion, it is impossible to round and smooth guiding flow stream
It crosses, it is unfavorable for improving flow and pressure.
Flow-guiding channel in common multistage pump is because of the channel for having staggered floor to commutate, 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 improving speed of production, 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, all there are production efficiencys for both the above
It is low, do not have facilitation to reducing cost.
Invention content
In view of the deficiencies of the prior art, the present invention provides a kind of multi-stage water pump encloseds to force flow-guiding structure, solves increasing
Press relatively low, processing step is more, and speed of production is slow, low production efficiency, to reducing the problem of cost is unfavorable.
In order to achieve the above object, the present invention is achieved by the following technical programs：A kind of multi-stage water pump enclosed pressure is led
Flow structure, including pump shell and the guide wheel being sleeved on inside pump shell；The front of the guide wheel is provided with integrated pressure
Splitter；Shunting crossover port is uniformly provided on the guide wheel and positioned at pressure splitter outer parabola direction；The water pump
The inside integrated setting of shell has pump shell circular arc flow deflector, and pump shell periphery is uniformly provided with pump group assembling screw
Hole；The center of the pump shell and guide wheel correspondence offers pump shaft hole.
As present invention further optimization scheme, dowel hole is offered on the guide wheel, and axis pin runs through positioning pin
Hole will be fixed between pump shell circular arc flow deflector and guide wheel.
As present invention further optimization scheme, the pressure splitter is at least provided with 8, and uniform circular is distributed
On guide wheel.
As present invention further optimization scheme, the back side of the guide wheel is evenly arranged with forcing splitter cooperation
Staggered floor water conservancy diversion inclined-plane.
As present invention further optimization scheme, the pump shell circular arc flow deflector at least provided with 8, and uniformly
The inside of pump shell is distributed in, and extends to the center of pump shell, until sencond stage impeller water inlet.
Advantageous effect
The present invention provides a kind of multi-stage water pump encloseds to force flow-guiding structure；Has following advantageous effect：
（1）, the multi-stage water pump enclosed force flow-guiding structure, can with it is more than two-stage it is multi-stage superimposed series winding use, the rim of the mouth of link is set
Identical size is calculated as, radial direction faying face is equipped with seal groove, can realize quick assembling and pressure-resistant function, the root before production is dispatched from the factory
According to the combination that series is needed to realize different series.
（2）, the multi-stage water pump enclosed force flow-guiding structure, after combination form 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 set 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 guiding flow staggered floor it is round and smooth rotate into subordinate'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, can be used numerically controlled lathe High-speed machining, 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.
