Description
Technical Field
The utility model relates to an impeller technical field, concretely relates to self priming pump vacuum impeller.
Background
The working principle of the vertical self-priming pump is as follows: before the water pump is started, the pump shell is filled with water, after the water pump is started, the impeller rotates at high speed to make the water in the impeller channel flow to the outlet of the water pump, at this time, the inlet is vacuumed, so that the one-way check valve opens the air in the suction pipe, and the air enters the pump and reaches the outer edge through the impeller, therefore, one of the important parts determining the performance of the pump is the impeller, and the impeller is widely applied in daily life and industrial production as a necessary part of the water pump.
The impeller that has now is in the in-service use in-process, and the fluid is big and the cavitation phenomenon can damage the impeller to high-speed rotatory impeller resistance, and nevertheless traditional impeller blade is very troublesome to its maintenance work of dismantling the replacement, and is very inconvenient, and in addition, the impeller probably collides with the grit in the aquatic when absorbing water and leads to the damage of blade, can lead to beating the tooth seriously for the inside damage that produces of self priming pump.
SUMMERY OF THE UTILITY MODEL
In order to overcome the defects of the prior art, the utility model provides a novel self-priming pump vacuum impeller can solve the technical problem in the background art.
The utility model discloses a following technical scheme realizes: a vacuum impeller of a self-priming pump comprises an impeller body, wherein the impeller is sleeved on a main shaft, and a shaft sleeve is arranged between the main shaft and the impeller;
the impeller comprises an impeller body and is characterized in that blades are arranged on the impeller body, the blades are uniformly arranged along the circle center of the impeller body, each blade consists of a plurality of blade assemblies, two blades are arranged on each blade assembly, a mounting plate is arranged at the root of each blade assembly, three mounting holes are formed in each mounting plate, threaded holes are formed in corresponding positions of the impeller body, and the blade assemblies are fastened to the impeller body through screws;
still be provided with the protective sheath on every blade subassembly, the protective sheath cover is established at the outer edge of flabellum, and the outer edge of flabellum is hugged closely to the protective sheath, be provided with the screw hole on the protective sheath, be provided with corresponding through-hole on the outer edge of flabellum, the protective sheath passes through the screw fastening to the flabellum on.
Preferably, the protective sleeve is a tungsten steel alloy protective sleeve.
The utility model discloses for prior art, be provided with the independent blade subassembly of several on the impeller of design, set up the flabellum on this blade subassembly, the blade subassembly passes through the screw-up to the impeller body on, can realize dismantling fast, simultaneously, has set up the protective sheath on the flabellum, adopts the alloy protective sheath to prevent that the flabellum from being damaged, the life of extension self priming pump.

Detailed Description
The present invention will be further described with reference to the accompanying drawings and the detailed description, and it should be noted that the embodiments or technical features described below can be arbitrarily combined to form a new embodiment without conflict.
The utility model is further explained with the attached figures 1 and 2, and the self-priming pump vacuum impeller comprises an impeller body 1, wherein the impeller is sleeved on a main shaft 2, and a shaft sleeve 3 is arranged between the main shaft 2 and the impeller;
the impeller comprises an impeller body 1 and is characterized in that blades are arranged on the impeller body 1, the blades are uniformly arranged along the circle center of the impeller body 1, each blade consists of a plurality of blade assemblies 4, each blade assembly 4 is provided with two blades, the root of each blade assembly 4 is provided with a mounting plate 41, the mounting plate 41 is provided with three mounting holes 42, the corresponding position of the impeller body 1 is provided with a threaded hole 51, and the blade assemblies 4 are fastened to the impeller body 1 through screws;
constitute a blade subassembly 4 through two flabellums, loop through the screw fastening to impeller body 1 with blade subassembly 4 on, can make things convenient for blade batch change when damaging, avoid appearing the blade part damage on the impeller but will change the problem of impeller.
Simultaneously, still be provided with protective sheath 5 on every blade subassembly 4, the outer edge at the flabellum is established to protective sheath 5 cover, and protective sheath 5 hugs closely the outer edge of flabellum, be provided with screw hole 51 on the protective sheath 5, the flabellum is provided with corresponding through-hole on following outward, protective sheath 5 passes through the screw fastening to the flabellum on. The protective sheath 5 that sets up can prevent that the impeller from at the during operation, the flabellum and the grit striking in the rivers, the flabellum damage that leads to.
Further, the protective sleeve 5 is a tungsten steel alloy protective sleeve 5. The tungsten steel alloy has higher strength and can effectively protect the weakest outer edge part on the leaf idea component.
The above embodiments are only preferred embodiments of the present invention, and the protection scope of the present invention cannot be limited thereby, and any insubstantial changes and substitutions made by those skilled in the art based on the present invention are all within the protection scope of the present invention.
