Abstract
The utility model discloses a guide vane of a submersible pump for a deep well, and is characterized in that a curved surface of the guide vane is provided with an upper contour line (1) and a lower contour line (2), which are round curves, the round curve of the lower contour line (2) is parallel to the upper contour line (1), and is downwards inclined at a certain angle on a water inlet (3) of the guide vane. The utility model has the advantages that: in comparison with the original cylindrical curved guide vane of the submersible pump, the lower contour line is downwards inclined at a certain angle, so that the guide vane of the submersible pump keeps a larger water inlet region, and a diffusion channel is formed by a cylindrical curved surface formed by a parallel part of the upper contour line and the lower contour line, and a cylindrical curved surface part of the next blade, so that the diffusion capacity of the guide vane is enhanced.
Description
Technical field
The utility model relates to a kind of well submersible pump guide vanes, relates in particular to a kind of stator that is overcoming the excessive well that higher overcurrent efficient can be arranged again of axial dimension and use with submersible pump.
Background technique
At present, well both domestic and external can be summarized as two kinds with submersible pump.A kind of S of being shape runner well submersible pump adopts spatial guide blade.The pump efficiency of this form is higher, and flow also conforms to the national Specification value with lift.But, the well submersible pump of this form, its axial dimension is larger, and the manufacture difficulty of blade is larger, and cost of production is higher, and therefore, its overall economic efficiency is very low.Another kind is stator well submersible pump radially, adopts the radial stator.The stator of this form, although overcome structural difficulty, its hydraulic performance is relatively not high.Hence one can see that, and the form of stator plays vital effect.Traditional radially stator is comprised of guide vane-annular space-inversion section, and its return guide vane entrance location is generally less than outside diameter, and it is inboard to be positioned at the guide vane outlet, and this stator is mainly used in sectional type multi-stage pump.And in recent years, at home and abroad some deep-well pumps and multistage centrifugal pump, developing gradually some new guide vane structures, its typical structure has: 1) be with positive and negative cylinder stator; The similar conventional construction form of this guide vane structure, but its front and back guide blade position is in same external diameter, does not have annulus.2) only be with the cylinder return guide vane; This guide vane structure does not have the guide vane part, and liquid stream out directly enters leg-of-mutton vane inlet district from the impeller periphery.3) return guide vane of import distortion; This stator is on the second basis, for better adapting to impeller liquid stream out, makes its smooth-going being transitioned in the stator, and vane inlet is designed to distorted shape.4) flow channel type guide blade.This guide vane structure compactness and positive and negative stator are connected, and its overcurrent efficient is higher than general positive and negative guide vane structure, but the casting difficulty.
Summary of the invention
In order to overcome existing well with the deficiency of submersible pump guide vanes, the invention provides a kind of novel well submersible pump guide vanes, axial dimension that can the customer service pump is excessive, can improve again the overcurrent efficient of stator, have simple in structurely, cost is low, the advantage of convenient processing and manufacture, thus reach the energy-conservation purpose that subtracts material.
A kind of well submersible pump guide vanes, it is characterized in that, be distributed with two upper profile line and lower whorl profiles that are circular curve on described each stator spoon of blade border, the circular curve of described lower whorl profile is parallel with described upper profile line and at the downward-sloping several angle in the water inlet of stator.
The beneficial effects of the utility model are, relatively original Cylinder Surface submersible pump guide vanes, the bottom profiled alignment several angle that has a down dip makes submersible pump guide vanes keep larger inlet area, the Cylinder Surface that upper profile line and bottom profiled line parallel partly consist of then can partly form the diffusion passage with the Cylinder Surface of next blade, strengthen the diffusion ability of stator, therefore improved the overcurrent efficient of stator.Simultaneously, the casting of this structure is also very convenient.
Description of drawings
Fig. 1 is the structural design drawing of stator blade.
Profile line, 2. lower whorl profile, 3. water intake on 1. among the figure.
Embodiment
Below in conjunction with drawings and Examples the utility model is further specified.
Starting point of the present invention is, on original submersible pump guide vanes basis that is Cylinder Surface, the submersible pump guide vanes curved surface is transformed into the distortion curved surface and two parts of Cylinder Surface form namely cylinder bending stator.Concrete operation step is: select an open well submersible pump guide vanes that is Cylinder Surface, the border of Cylinder Surface is distributed with two upper profile lines that are parallel to each other and lower whorl profile on the stator; With the bottom profiled alignment of stator in the water inlet several angle that has a down dip.
Shown in Figure 1 by reference to the accompanying drawings, a kind of well submersible pump guide vanes, it is characterized in that, be distributed with two upper profile line 1 and lower whorl profiles 2 that are circular curve on the described stator spoon of blade border, the circular curve of described lower whorl profile 2 and described upper profile line 1 are parallel and at water intake 3 places of stator downward-sloping 15 °.
By with the Cylinder Surface of submersible pump guide vanes the lower whorl profile of its inlet part 2 downward-sloping 15 °, relatively original Cylinder Surface submersible pump guide vanes, kept larger inlet area, the Cylinder Surface that upper profile line 1 and lower whorl profile 2 parallel portion consist of then can partly form the diffusion passage with the Cylinder Surface of next blade, strengthen the diffusion ability of stator, therefore improved the overcurrent efficient of stator.
Claims (2)
1. well submersible pump guide vanes, it is characterized in that, be distributed with two upper profile line (1) and lower whorl profiles (2) that are circular curve on the described stator spoon of blade, the circular curve of described lower whorl profile (2) is parallel with described upper profile line (1) and locate downward-sloping several angle at the water intake (3) of stator.
2. a kind of well submersible pump guide vanes according to claim 1 is characterized in that, the circular curve of lower whorl profile (2) is located downward-sloping 15 ° at the water intake (3) of stator.
