Abstract
The invention discloses a vortex pump cover with a splitter blade in an outlet. The vortex pump cover comprises the splitter blade, the outlet, an inlet, connecting holes and a passageway, wherein the outlet splitter blade is fixed in the outlet. The splitter blade is a constant splitter blade, the splitter blade can be designed to be of different types according to the flow velocity angle at the outlet under a rated working condition, and the mounting angle is the same as the flow velocity angle, so that it is guaranteed that a vortex pump operates with the highest efficiency under the rated working condition. Through the structural design, the outlet flow velocity characteristic and the efficiency-flow characteristic of the vortex pump can be improved, outlet noise can be lowered, and the performance of the vortex pump is improved.
Description
Technical field
The present invention relates to a kind of pump cover, relate in particular to a kind of peripheral pump pump cover with splitterr vanes for outlet, belong to stream
Body mechanical field.
Background technology
Existing peripheral pump product is usually operated under declared working condition, but because peripheral pump is less efficient, not more than
50%, the efficiency of most of peripheral pumps is in 10-40%, and the cavitation performance of peripheral pump is poor, leads to peripheral pump range of application narrow.By
The interaction result of fluid in the presence of radial direction vortex and longitudinal vortex and flow passage impeller, peripheral pump internal flow is very
Complexity, enters because the angle of current changes after pump cover exports from the fluid flowing out in impeller and runner through blending, may
There are larger flow losses, adopt homalographic cross-sectional exit traditional peripheral pump pump cover it is impossible to ensure the outlet angle of current and pump cover more
Exit bias is consistent.
Therefore, based on the description above, in the urgent need to designing a kind of new peripheral pump pump cover, the outlet improving peripheral pump is special
Property, the aggregate efficiency of peripheral pump is improved with this, and reduces vortex pump noise.
Content of the invention
The purpose of the present invention is that and solves the above problems.For this reason, the present invention provides a kind of rotation with splitterr vanes for outlet
Whirlpool pump pump cover is it is therefore an objective to from improving peripheral pump exit flow field, pressure field, wash away tail by arranging splitterr vanes in exit
Stream, is effectively prevented generation and the development of wake flow, thus increasing pump lift, can effectively improve exit velocity distribution, improving pump
Performance.
For achieving the above object, the technical scheme that the present invention takes is：
A kind of peripheral pump pump cover with splitterr vanes for outlet, including splitterr vanes 1, exports 2, import 3, connecting hole 4, runner 5, goes out
Mouth splitterr vanes are fixed in outlet.
Described splitterr vanes be etc. straight splitterr vanes, splitterr vanes blade profile should be according to flow velocity angle in exit under declared working condition
Difference be designed, established angle is identical with flow velocity angle.
Described splitterr vanes determine according to velocity flow profile in runner position, for just, being partial to low speed face during deflection high speed surface
When be negative, the 50% ~ 80% of a length of outlet flow length of described splitterr vanes, a height of outlet flow height of described splitterr vanes
90%~95%.
Brief description
Fig. 1 is the structural representation of the present invention.
Fig. 2 is embodiments of the invention 1 schematic diagram.
Fig. 3 is embodiments of the invention 2 schematic diagram.
In figure 1- splitterr vanes；2- exports；3- import；4- connecting hole；5- runner.
Specific embodiment
Below against accompanying drawing, by the description to embodiment, the specific embodiment of the present invention is made further details of
Illustrate it is therefore an objective to help those skilled in the art to have more complete, accurate and deep reason to the design of the present invention, technical scheme
Solution, and contribute to its enforcement.
The peripheral pump pump cover with splitterr vanes for a kind of outlet as shown in Figure 1, includes splitterr vanes 1, outlet 2, import 3,
Connecting hole 4, runner 5, outlet manifold blade is fixed in outlet.
Fig. 2 is a kind of embodiment of the present invention, and in outlet manifold blade, the string of a musical instrument is overlapped with outlet flow center line, splitterr vanes
Placement direction is consistent with Way out.When peripheral pump design point water export angle is equal to outlet flow drift angle, the present invention can
Reduce the secondary flow of outlet, reduce boundary layer loss.
Fig. 3 is another kind of embodiment of the present invention, and in outlet manifold blade, the string of a musical instrument is angled with outlet flow center line
α, middle mid-chord and outlet flow cross-section center distance are a.When peripheral pump exit flow field and outlet flow Incomplete matching
When, design parameter should be determined according to actual tests situation.
The invention has the beneficial effects as follows：Splitterr vanes are used in peripheral pump in order to improve the efficiency of pump.Using shunting leaf
Piece can improve impeller outlet and casing outlet mouth Flow Field Distribution, increase lift, improve cavitation performance, improve " penetrating of impeller outlet
Flow a tail " structure, reduces energy consumption, increases the stability run and reliability, reduce vibration and noise, improve stable
Property, impeller outlet diffusion can be reduced, improve slip coefficient, you can to improve pump head, or reduce under identical lift
Impeller diameter, thus reducing disc friction, improves efficiency.
Embodiment described above, the simply present invention more preferably specific embodiment, those skilled in the art is at this
The usual variations and alternatives carrying out in the range of inventive technique scheme all should comprise within the scope of the present invention.
