Description
Technical field
The utility model belongs to blade wheel of slurry pump technical field, more particularly to a kind of for conveying high rigidity, low granularity liquid
The centrifugal slush pump supercharging impeller of body.
Background technology
Unshrouded impeller, without cover plate, is simple to manufacture in blade both sides, is easy to clean, containing relatively large suspension suitable for conveying
Material, less efficient, the fluid pressure of conveying is not high.In general delivery pump is mostly such.Double shrouded wheel is in impeller in blade
There are front and rear cover plate, efficiency high, suitable for conveying cleaning liquid free from foreign meter in both sides.In general centrifugal pump impeller is mostly such.
Half-opened impeller, without cover plate, and has cover plate in suction inlet side in opposite side, suitable for conveying easily precipitation or the thing containing particle
Material, efficiency are relatively low.In general slush pump is mostly such.
Slush pump, refer in drilling process to the machinery of the conveying flushing liquor such as mud or water in drilling.Slush pump is to bore
Visit the important component of equipment.And centrifugal mud pump can be used generally for various liquid streams and pressure head condition.But in slurry
Particle and liquid can pass through impeller at different paths, i.e., the vortex that slurry is formed offset or divided from the face of pump blade
From there is turbulent phenomenon.This imagination can cause the abrasion of impeller and the loss of liquid stream, reduce pressure of the liquid stream to impeller,
Transfer efficiency is reduced simultaneously, causes the waste of the energy.
At present, the guidance quality very little that impeller cover, blade and housing can provide to slurry, turbulent phenomenon occur frequent.In
A kind of blade wheel of slurry pump is disclosed in state utility application prospectus CN206111655U, to blade diameter, is gone out
Mouth diameter and outlet stream width are improved, and are directly justified provided with front end water conservancy diversion at impeller inlet, and blade is close to import
Position is formed to the inclined guiding intermediate incline of import, and the guiding that angle of inclination is gradually reduced is formed in succession after guiding intermediate incline
Inclined-plane.The transport of solid-liquid two-phase bulky grain fluid is mainly used in, is advantageous to the flowing of bulky grain fluid, reduces the viscous wall of fluid
Wall attachment effect, and the abrasion between impeller.But the phenomenon for still not overcoming turbulent flow to frequently occur, the loss of liquid stream be not slow
Solution, pressurized effect unobvious, and conevying efficiency is not improved accordingly.
Utility model content
It is intended to overcome above-mentioned the deficiencies in the prior art, the technical problems to be solved in the utility model is to propose one
Kind slush pump supercharging impeller, to improve impeller to the pressurized effect of slurry and the conevying efficiency of slurry.
Technical scheme is used by the utility model solves its technical problem：Slush pump supercharging impeller, the impeller are
Half-opened impeller, including wheel disc, an end face of the wheel disc are provided with multiple camber blades, and the camber blades are from the wheel disc
Center extend laterally, the front of the camber blades is pusher working face, and the back side of the camber blades is non-working surface,
Another end face of the wheel disc is provided with multiple prismatic blades, radial laterally point of center of the prismatic blade along the wheel disc
Cloth；The pusher working face of the camber blades is provided with slurry runner.
Further, the slurry runner is arranged at the camber blades and the joint portion of the wheel side surface.
Further, the slurry runner is that the outward flange of the pusher working face of the camber blades is outwardly with the wheel
The groove that the combination end face of disk is formed.
Further, the slurry runner is the groove being opened on the pusher working face of the camber blades.
Further, the bearing of trend of the slurry runner is consistent with the bearing of trend of the camber blades.
After employing above-mentioned technical proposal, the beneficial effects of the utility model are：
The bending direction of camber blades is consistent with the direction of rotation of impeller, and the pusher working face of camber blades is provided with slurry
Runner.The outward flange outwardly (arc transition) of the pusher working face of camber blades and the combination end face of wheel disc form recessed
Groove, or the groove being opened on the pusher working face of the camber blades, these grooves are exactly slurry runner.Slurry runner
Bearing of trend is towards the direction of rotation of impeller.When impeller rotates, the slurry runner of blade pusher working face is used to be pressurized water conservancy diversion,
Non-working surface can form negative pressure, and slime water can flow rapidly into the presence of atmospheric pressure.The setting of slurry runner makes in slurry
Particle and liquid impeller can be passed through with specific path, avoid slurry from being offset from the face of blade, separate and turbulent flow occur and show
As.Improve impeller and conevying efficiency is also improved to the pressurized effect of slurry.Wheel backface designs prismatic blade, main to play sealing work
With.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model；
Fig. 2 is the schematic rear view of Fig. 1 slush pump supercharging impellers；
In figure：1- wheel discs, 2- camber blades, 21- slurry runners, 3- prismatic blades.
Embodiment
The utility model is described in further detail with reference to drawings and Examples.
As depicted in figs. 1 and 2, slush pump supercharging impeller is half-opened impeller, and an end face of wheel disc 1 is provided with multiple bendings
Blade 2, camber blades 2 extend laterally from the center of wheel disc 1, the bending direction of camber blades 2 and the direction of rotation one of impeller
Cause, the front of camber blades 2 is pusher working face, and the pusher working face of camber blades 2 is provided with slurry runner 21.Slurry runner
21 are arranged at the joint portion of camber blades 2 and the end face of wheel disc 1.The bearing of trend of slurry runner 21 and the extension side of camber blades 2
It is consistent to (bending direction).That is the bearing of trend of slurry runner 21 is towards the direction of rotation of impeller.
The formation of slurry runner 21 has a two ways, 1, slurry runner 21 be camber blades 2 pusher working face outside
The groove that the combination end face of edge outwardly (arc transition) and wheel disc 1 is formed,；2nd, slurry runner 21 is to be opened in camber blades
Groove on 2 pusher working face.
The back side of camber blades 2 is non-working surface.Another end face of wheel disc 1 is provided with multiple prismatic blades 3, the edge of prismatic blade 3
The radial distribution laterally of the center of wheel disc 1, prismatic blade 3 are mainly used in sealing.
