Abstract
The utility model discloses a high-efficiency multi-stage centrifugal water pump guide wheel, which makes an improvement on the basis of an original centrifugal water pump guide wheel. In the transition zone, the transition between two guide vane outlets adopts a slant face, and the slant face is arranged outside a guide vane which is between the two guide vane outlets; the slant face is gradually formed along the direction of the liquid flow from a high position to a low position. The high-efficiency multi-stage centrifugal water pump guide wheel is suitable for a molded multi-stage high-efficiency water pump; namely, the original dimension of a water guide water wheel does not need to be redesigned, the blade profile molded line of the guide water wheel of an original pump can not be affected, and a slim improvement is just needed at the time of casting. Also, a wedge with a slant face can be manufactured according to the shape of the part between the two guide vanes, and the wedge with the slant face is fixed on the existing guide water wheel. The novel water pump guide wheel can improve the pump efficiency by 3%.
Description
The utility model relates to a kind of high-efficiency multi-stage centrifugal pump water guide wheel, and this water guide wheel is suitable for multistage water pump.
Before this reality has novel making, the various multistage water pump of use (comprising homemade water pump and import water pump), because unreasonable structure, there is twice bump in current in transition zone.As shown in Figure 2, current enter the return guide vane runner from guide vane outlet ABCD through transition zone, exist strong bump vortex in transition zone.Current through behind the secondary impact, enter the return guide vane runner in transition zone, current enter dead angle area ABCDFE after guide vane outlet ABCD flows out, produce bump for the first time.Clash into dividing plate again on the current direction of bump back, produce bump for the second time, then import the return guide vane runner.So just produce bigger bump loss.
The purpose of this utility model is exactly a kind of high-efficiency multi-stage centrifugal pump water guide wheel of developing in order to overcome deficiency of the prior art.
The purpose of this utility model can reach by following measure:
This water guide wheel also is made up of guide vane, return guide vane and housing.Different is: as shown in Figure 3, in transition zone, adopt inclined-plane (7) transition between the outlet of two guide vanes, and this inclined-plane (7) guide vane outside between this two guide vanes outlet, inclined-plane (7) form from low to high gradually along liquid flow direction.
The purpose of this utility model can also reach by following measure:
Inclined-plane (7) can be a curved surface.
By the shape between two guide vanes, make a voussoir with an inclined-plane, ADEFAD as shown in Figure 3, and this voussoir is fixed between the outlet of two guide vanes.Fixedly voussoir is applicable to the technical innovation that existing water guide is taken turns between two guide vanes.
The explanation of accompanying drawing drawing:
Fig. 1 is an overall schematic of the present utility model.
Fig. 2 is the schematic representation of shape, wherein (8) return guide vane between the two guide vanes outlets in the prior art.
Fig. 3 is the schematic representation of shape between the two guide vanes outlets in the utility model.
Fig. 4 is the 1-6 position profile schematic representation of Fig. 1.
Fig. 5 be the A of Fig. 1 to schematic representation, (7) inclined-plane wherein.
The utlity model has following advantage:
1, reduces the bump of current, can improve pump efficiency 3%.
2, make simply small investment.
3, be applicable to the multi-stage, efficient water pump of having finalized the design, namely former other size to the water guide wheel does not need redesign, does not affect former pump water guide wheel blade profile molded lines. As long as when casting, improve slightly.
4, can be used for having the technological transformation of water guide wheel now.
Be described in further detail below in conjunction with accompanying drawing:
Shown in Fig. 1-5, this high-efficiency multi-stage centrifugal pump water guide wheel is the improvement of carrying out on the original structure basis.Water guide wheel before improving, in transition zone, between the outlet of two guide vanes is the plane, and this has just caused liquid hitting that transition zone is hit, in order to address this problem, on the original structure basis, in transition zone, adopt chamfered transition between the outlet of two guide vanes, the guide vane outside of this inclined-plane between the outlet of two guide vanes, the inclined-plane forms from low to high gradually along liquid flow direction.This inclined-plane can be by manufacturing a voussoir that has the inclined-plane, and this voussoir is welded on the method that former water guide takes turns between two guide vanes realizes; Also can keep original size and shape by when the casting water guide is taken turns, the method that just directly casts out an inclined-plane between the outlet of two guide vanes realizes.
