Specific implementation mode
For that can further appreciate that present disclosure, feature and effect, the following examples are hereby given, and coordinates attached drawing detailed
It is described as follows：
As shown in Figures 1 to 6, a kind of anti-silt particle turbulent flow blade guiding wheel is present embodiments provided, is led by single-stage impeller 6 and single-stage
Shell 7 is assembled, and innovative design on the basis of conventional centrifugal impeller of single-stage impeller 6 is turbulent flow impeller, the outer diameter of turbulent flow impeller
Size is consistent with same discharge capacity routine impeller size.Turbulent flow impeller leads 7 inner rotation of shell in single-stage, constitutes single-stage turbulent flow blade guiding wheel.
Single-stage turbulent flow blade guiding wheel constitutes turbulent flow pump after single-unit pump discharge 8 and single-unit pump intake 9 are installed respectively.
As shown in Figure 1 to Figure 3, the blade of the single-stage impeller 6 of the present embodiment includes lifting 4 two kinds of blade 1 and turbulent flow blade,
It is identical with the quantity of turbulent flow blade 4 to lift blade 1.It is identical with the blade construction of conventional centrifugal impeller to lift blade 1, turbulent flow
Blade 2 increases the design of fracture 5 on the basis of lifting 1 conventional structure of blade, the setting of fracture 5 in 4 centre position of turbulent flow blade, by
The root of turbulent flow blade 4 extends to outer end edges, and turbulent flow blade 4 is made to form the structure type similar to U-shaped, such fluid stream
When through fracture 5, it will the variation of flow regime occurs due to circulation area variation.As shown in figure 4, the fracture of turbulent flow blade 4
There are 45 ° of rounded corners, the rounded corners, to increase the interference performance to fluid, can make within the scope of 45 ° -60 ° at edge
Turbulence effects are more obvious.
The thickness of turbulent flow blade 4 is that preferably 2-3mm, the thickness can ensure the intensity of turbulent flow blade 4.Turbulent flow blade 4
Entrance laying angle be preferably arranged to 25 ° -35 °, this angular range can reduce flow resistance, make the drainage of turbulent flow blade 4
Effect is more preferable.
Blade 1 and turbulent flow blade 4 are lifted according to 1:1 is evenly distributed on single-stage impeller 6 circumferentially at equal intervals, and lifts leaf
Piece 1 and turbulent flow blade 4 it is spaced be alternately arranged arrangement, can effectively be realized while lifting liquid in this way its flow shape
The change of state.The quantity of turbulent flow blade 4 is traditionally arranged to be 4-7 pieces, which can guarantee the lasting turbulence state of fluid.
The impeller cover 3 of single-stage impeller 6 is provided with a circle rectangle gear teeth 2, and the rectangle gear teeth 2 are radially uniform to be arranged in impeller cover
On the outer ring anchor ring of plate 3, and the thickness of all rectangle gear teeth 2 is impartial.2 one side of the rectangle gear teeth is for stirring sedimentary clay
Sand, gap can keep in part precipitated mud and sand between the another aspect rectangle gear teeth 2, prevent blade wear, therefore in single-stage impeller 6
Rotation process in, provide help to prevent mud and sand silting and precipitated mud and sand from handling.Single-stage is led shell 7 and is provided with and the rectangle gear teeth 2
Matched structure, to which single-stage leads shell 7 with single-stage impeller 6 with the use of turbulent flow blade guiding wheel is formed, as shown in Figure 5.
As shown in fig. 6, the present invention installed respectively in the single-unit pump discharge 8 and single-unit pump intake 9 of oil-immersed pump it is a certain proportion of
Above-mentioned turbulent flow blade guiding wheel constitutes turbulent flow pump.The turbulent flow leaf that the single-unit pump discharge 8 and single-unit pump intake 9 of turbulent flow pump assemble respectively
Guide wheel series is equal, and turbulent flow blade guiding wheel series and conventional blade guiding wheel series ratio are 8：1~10:1.In this way, turning in turbulent flow pump
Dynamic process, lifting blade 1 provide centrifugation lifting effect, and turbulent flow blade 4 changes fluid flow state by fracture 5, plays anti-mud
Sand deposition blocks the effect of runner, bearing.
It is concatenated in use, only in upper section oil-immersed pump outlet section and lower section oil-immersed pump when needing multistage oil-immersed pump in practical application
Entrance installs turbulent flow blade guiding wheel.
The present invention is used increases by 2 structure design of the rectangle gear teeth in impeller cover 3, changes simultaneously impeller blade routine distributed mode
Formula is realized that lifting blade 1 is handed over the interval of turbulent flow blade 4 and is mutually arranged, in the case where ensureing that single-stage blade guiding wheel lift height is constant,
Change flow regime of the liquid in runner, to reduce accumulation of the silt particle in impeller channel and bearing, ensures submersible electric pump
Unit normal operation under the hole condition containing silt particle.
Although the preferred embodiment of the present invention is described above in conjunction with attached drawing, the invention is not limited in upper
The specific implementation mode stated, the above mentioned embodiment is only schematical, be not it is restrictive, this field it is common
Technical staff under the inspiration of the present invention, is not departing from invention objective and scope of the claimed protection, can be with
The specific transformation of many forms is made, within these are all belonged to the scope of protection of the present invention.
