Abstract
The utility model relates to a submersible pump vortex electric pump with a ruffled blade, wherein an impeller of the vortex electric pump uses a bending blade, the bending blade is added with a part of front cover plate on the side of a common blade outlet. Circular flow is limited to convert to axial direction from the radial direction after adding a part of the front cover plate, thereby reducing the circular flow loss, and obviously increasing the lift and the efficiency in the total flow range.
Description
Technical field
The utility model relates to fluid machinery, refers in particular to the diving eddy current electric pump of band edge folding blades.
Background technique
The special construction of turbulence pump is that its impeller is held back among the pump chamber of pumping chamber back, make the bigger space of the interior formation of spiral case promptly not have phyllocyst, in the no phyllocyst of impeller front, form during the impeller rotation and connect stream and circular flow, perforation stream enters pump chamber by runner between impeller blade and flows out, and circular flow then circulates in no phyllocyst.Because the good passing capacity of turbulence pump, so it is increasingly extensive in sector applications such as mine, chemical industry.But owing to there is circular flow, the turbulence pump hydraulic loss is very big.
At present, what known turbulence pump adopted is the radioactivity impeller, and this impeller hydraulic performance is bad, can not effectively improve turbulence pump internal flow situation, and eddy current lift of pump and efficient are reduced greatly.
Summary of the invention
For addressing the above problem, the utility model adopts the blade of band flanging, and it has effectively limited diving eddy current electric pump and has radially transferred axial circulating to, has reduced the circular flow loss, has improved eddy current lift of pump and efficient.
Realize that above-mentioned purpose adopted technological scheme be:
Turbulence pump adopts the blade of band flanging, and it is for to add the part front shroud at the common blade outlet side.After adding the part front shroud, limited and radially transferred axial circulating to, reduced the circular flow loss.
The beneficial effects of the utility model are: reduce hydraulic loss, lift and efficient all are significantly improved in whole range of flow.
The utility model is on probation through the user, and reaction effect is good, can reduce investment outlay effectively, energy saving.

Among the figure: 1. motor, 2. main shaft, 3. impeller, 4. spiral case, 5. support, 6. blade, 7. wheel hub, 8. back shroud, 9. flanging.
Embodiment
As Fig. 1～shown in Figure 4, the used impeller 3 of diving turbulence pump that the utility model is established described band edge folding blades comprises blade 6, wheel hub 7 and back shroud 8.What described among the figure is radial impeller, if make the band bending blade impeller, does not also influence enforcement of the present invention, because the present invention's control is the structure of blade.Impeller 3 is installed in the spiral case 4, with spiral case outlet place face certain distance is arranged.When diving turbulence pump when operation, the impeller 3 with edge folding blades can improve the mobility status in the spiral case 4.
The blade of described impeller 3 has flanging 9.During the operation of diving turbulence pump, flanging 9 can limit and radially transfer axial circulating to, has reduced the circular flow loss, improves lift and efficient.
