Abstract
The present invention discloses a kind of high-efficiency abrasion-proof ore pulp impeller of pump, including wheel hub and cover board, wheel hub is equipped with the interconnecting piece being connected with driving device, the cover board is located at the outer whole body of the wheel hub, the cover board includes front shroud and back shroud, the circumferentially-spaced of back shroud is disposed with multiple blades, and the thickness of the back shroud is 1.3~2.1 times of protecgulum plate thickness.Traditional design is that front and rear cover plate is equally thick, since the wear extent of inlet pressure and solid inertial flow back shroud is significantly greater than front shroud, the application uses the thickness of back shroud for 1.3~2.1 times of protecgulum plate thickness, so that front and rear cover plate theoretically wears synchronization, reduce the number for replacing back shroud, it avoids wasting, has saved the cost of enterprise.
Description
Technical field
The present invention relates to a kind of ore slurry pumps, and in particular to a kind of high-efficiency abrasion-proof ore pulp impeller of pump.
Background technology
Ore slurry pump is that the equipment for sending ore pulp is raised in ore dressing plant, is the capital equipment of tailing Hydraulic Transportation System, tailing pumping plant
Host.There is two class of centrifugal ore slurry pump and reciprocating ore slurry pump.
The impeller of traditional ore slurry pump is that front and rear cover plate is equally thick, due to inlet pressure and solid inertial flow, back shroud
Wear extent is significantly greater than front shroud, this allows for front shroud when back shroud needs replacing and remains to use, and causes the waste of resource；It passes
The impeller the Hydraulic Design of system ore slurry pump is 5 blades, and impeller quantity is more, and weight is big, and passability is poor, is unfavorable for the logical of bulky grain
It crosses.
Invention content
To solve the above-mentioned problems, the present invention provides a kind of high-efficiency abrasion-proof ore pulp impeller of pump so that front and rear cover plate abrasion is same
Step, reduces the replacement number of cover board, cost-effective.
To achieve the goals above, the present invention uses following technical scheme：A kind of high-efficiency abrasion-proof ore pulp impeller of pump, including wheel
Hub and cover board, wheel hub are equipped with the interconnecting piece being connected with driving device, and the cover board is located at the outer whole body of the wheel hub, described
Cover board include front shroud and back shroud, the circumferentially-spaced of back shroud is disposed with multiple blades, and the thickness of the back shroud is
1.3~2.1 times of protecgulum plate thickness.
What the present invention was brought has the beneficial effect that：Traditional design is that front and rear cover plate is equally thick, due to inlet pressure and efflux of solids
The wear extent of dynamic inertia back shroud is significantly greater than front shroud, the application use the thickness of back shroud for protecgulum plate thickness 1.3~
2.1 times so that front and rear cover plate theoretically wears synchronization, reduces the number for replacing back shroud, avoids wasting, saved enterprise at
This.
Description of the drawings
Fig. 1 is the partial sectional view of the present invention；
Fig. 2 is the front view of the present invention；
Fig. 3 is the stereogram of the present invention.
Specific implementation mode
The present invention is further detailed in 1-3 below in conjunction with the accompanying drawings.
As shown in Figs. 1-3, a kind of high-efficiency abrasion-proof ore pulp impeller of pump, including wheel hub and cover board 1, wheel hub is equipped with to be filled with driving
Connected interconnecting piece is set, the cover board 1 is located at the outer whole body of the wheel hub, and the cover board 1 includes front shroud 11 and rear cover
Plate 12, the circumferentially-spaced of back shroud 12 are disposed with multiple blades 2, and the thickness of the back shroud 12 is 11 thickness of front shroud
1.3~2.1 times.The thickness of back shroud is 1.3~2.1 times of protecgulum plate thickness so that front and rear cover plate theoretically wears synchronization, subtracts
The number for replacing back shroud less, avoids wasting, has saved the cost of enterprise.
Further, the blade 2 includes big blade 21 and vanelets 22, and each big 21 side of blade is fixed with leaflet
Piece 22.The design for increasing vanelets 22 between big blade 21 on back shroud 12, eliminates the vortex between runner, impeller is made to go out
Mouth flow velocity is uniformly smooth, reduces concentrated wear and energy loss, improves impeller service life and hydraulic efficiency.
Further, the big blade 21 is 4, and the vanelets 22 are 4.Conventionally employed is 5 great Ye
The form of piece, the application keep impeller passability good, are more advantageous to passing through for bulky grain, subtract simultaneously by reducing big blade quantity
The light weight of impeller.
Further, 1 molded line of blade is adjusted after being analyzed according to CFD fluid analysis softwares.
The molded line of blade is analyzed and optimized using advanced CFD fluid analysis software, has found influence efficient point
Key component, there is what is be directed to modifying to these places and verifying again so that the efficiency of impeller is significantly improved,
Impeller newly designed to impeller simulation test through CFD fluid analysis software, solid particle energy identical as the use parameter of 5 blade impellers
It is enough quickly pass through region at this.3-5% is improved through actual loading test reduced parameter same efficiency.
Further, the size of the blade 2 is consistent with existing traditional leaf blade size, the impeller size with it is existing
There is traditional impeller in the same size.Using the identical size design of traditional blades impeller, to enable the impeller being changed without
It is fitted into the case of other parts in pump, accomplishes the complete exchange with prophyll wheel.
Preferably, the thickness of the back shroud 12 is 1.5 times of 11 thickness of front shroud.Before the thickness of back shroud 12 is
1.5 times of 11 thickness of cover board, the wear-resisting synchronous degree highest of front and rear cover plate.
The basic principles and main features and the features of the present invention of the present invention have been shown and described above.The technology of the industry
Personnel are it should be appreciated that the present invention is not limited to the above embodiments, and the above embodiments and description only describe this
The principle of invention, without departing from the spirit and scope of the present invention, various changes and improvements may be made to the invention, these changes
Change and improvement is both fallen in the range of claimed invention.The scope of protection of present invention is by appended claims
And its equivalent thereof.
