Description
Technical field
The utility model is related to a kind of without submersible sewage impeller of pump is blocked, without stifled specifically in machinery field proof submersible sand discharging pump
Fill in impeller.
Background technology
Submersible sewage pump is the sewage pump of submersible type, can be torn the substances such as sewage medium-length fibre, bag, band, grass, cloth, cut-out,
Then smooth discharge, particularly suitable for conveying containing rigid solid, the liquid of fibre object and especially dirty, viscous, sliding liquid.Have
Two types：AS, AV type submersible sewage pump, water pump vane are cylinder iron made.Blade on water pump vane plays a major role again,
The shape and size of water pump vane have substantial connection with pump performance.Water pump vane generally can be divided into single-suction and double-suction type two
Kind, single-suction impeller is unilateral water suction, and small flow water pump impeller is mostly such pattern.Double-sided impeller absorbs water for both sides, big to flow
It measures water pump vane and uses double-sided impeller.Impeller is the core component of water pump, is the main influence element of working efficiency.Specific
Under operating mode, if Impeller Design is bad will to generate hydraulic loss and gap loss at pump intake and blade.So selecting
Aspect has to the water pump vane manufacturer of selection profession, the problem of most critical is that reliability is asked for proof submersible sand discharging pump
Topic, because the use occasion of dredge pump is under liquid；The medium of conveying is the mixing liquid that some contain solid material；Pump and electricity
Machine is in close proximity；It pumps as vertical, rotatable parts weight bears that water pressure is in the same direction, and impeller rises in proof submersible sand discharging pump with impeller
To key effect, therefore situations such as impeller can be potentially encountered blocking in use.
Utility model content
The technical problems to be solved in the utility model is the defects of overcoming the prior art, is provided a kind of without blocking submersible sewage
Impeller of pump, anti-clogging simple in structure, working efficiency are efficient.
In order to solve the above-mentioned technical problem, the utility model provides following technical solution：
The utility model is a kind of without submersible sewage impeller of pump is blocked, including wheel hub on blade, on the blade below wheel hub
Upper cover plate is provided with, blade is provided with below the upper cover plate, quantity is five, and the blade is in crescent, respectively with described
It is arranged in a ring centered on the wheel hub center of circle on blade, cutting sheet described in cutting sheet is each provided on five blades positioned at described
The outer side of blade, and vertical with the direction of the blade cuts, is provided with lower cover below the blade, under the lower cover
Side is provided with blade lower hub, and wheel hub and the blade lower hub are in pie shape on the blade.
As a kind of optimal technical scheme of the utility model, the blade is fixed with the cutting sheet by screw and nut
Connection.
The advantageous effect that the utility model is reached is：The utility model is easy to use, in the hub altogether there are five settings
Blade, blade quantity multipotency increase runner number, and liquid flow velocity is allowed to accelerate to increase efficiency, ensure that blade is to liquid in runner
Control so that the working efficiency of blade is also more efficient, is contacted more comprehensively with dirty impurities in water, according to principle of hydrodynamics need
The medium to be pumped is directed in pump chamber, and pumped medium is from impeller by-pass flow.In this way, the length in pumped liquid medium
Fiber or solid matter are also pumped away together, can shred larger blocks of solid substance, so as to no longer block.In order to
It prevents filiform from being blocked caused by being wound on blade, is provided with cutting sheet on five blades, the cut direction phase with blade
Instead, the sundries that can not be cut for cut-off blade, the device structure is simple, highly practical.
Description of the drawings
Attached drawing is used to provide a further understanding of the present invention, and a part for constitution instruction, with this practicality
Novel embodiment for explaining the utility model, does not form the limitation to the utility model together.In the accompanying drawings：
Fig. 1 is the utility model subjectivity structure diagram；
Fig. 2 is the utility model side structure schematic diagram；
Fig. 3 is the utility model inner vanes distribution schematic diagram；
In figure：1st, wheel hub on blade；2nd, upper cover plate；3rd, blade；4th, lower cover；5th, cutting sheet；6th, blade lower hub.
Specific embodiment
The preferred embodiment of the utility model is illustrated below in conjunction with attached drawing, it should be understood that described herein excellent
Embodiment is selected to be only used for describing and explaining the present invention, is not used to limit the utility model.
Embodiment：As shown in Figs. 1-3, including wheel hub on blade 1,1 lower section of wheel hub is provided with upper cover plate 2 on the blade,
2 lower section of upper cover plate is provided with blade 3, and quantity is five, and the blade 3 is in crescent, respectively with wheel hub 1 on the blade
It is arranged in a ring centered on the center of circle, cutting sheet 5 described in cutting sheet 5 is each provided on five blades 3 it is located at the blade 3 leaning on
Outer side, and it is vertical with the direction of the blade 3 cutting, and 3 lower section of blade is provided with lower cover 4,4 lower section of lower cover
It is provided with blade lower hub 6, wheel hub 1 and the blade lower hub 6 are in pie shape on the blade.
In order to make this kind, without submersible sewage impeller of pump is blocked, easy to use, working efficiency is high, and the blade 3 is cut with described
Pitch cutting 5 is fixedly connected by screw and nut.
The utility model is easy to use, safety and stability, highly practical, by this without blocking submersible sewage impeller of pump dress during use
Enter in proof submersible sand discharging pump, start proof submersible sand discharging pump.The medium that needs pump is directed in pump chamber according to principle of hydrodynamics,
Pumped medium is from impeller by-pass flow.In this way, long fibre or solid matter in pumped liquid medium also together by
Pumping is gone out, and can shred larger blocks of solid substance, so as to no longer block.The cutting angle of blade 3 can not in order to prevent
Cut to filiform, on blade 3 winding cause blade 3 can not be cut and caused by blocking, on five blades 3 respectively
Cutting sheet 5 is provided with, cutting work is shared for the blade 3 in wheel hub, the medium-and-large-sized impurity of sewage is cut into small-sized impurity, with leaf
The perpendicular 90 degree of directions of cut direction of piece 3, cutting sheet 5 can not be cut miscellaneous for cut-off blade 3 because of cutting angle
Object, prevents blade 3 from cutting less than being wound into blade 3, the pressure of artificial work cleaning, manpower consumption after being reduced in this way per task
Alleviated, the device structure is simple, easy to use, safe.
Finally it should be noted that：The above descriptions are merely preferred embodiments of the present invention, is not limited to this
Utility model, although the utility model is described in detail with reference to the foregoing embodiments, for those skilled in the art
For, it can still modify to the technical solution recorded in foregoing embodiments or to which part technical characteristic
Carry out equivalent replacement.Within the spirit and principle of the utility model, any modification, equivalent replacement, improvement and so on,
It should be included within the scope of protection of this utility model.
