Abstract
A kind of impeller for self-priming pump, relate to pump valve field, comprise connecting bottom board and blade, described blade is fixed on the side of connecting bottom board, solve the self-suction pump impeller of prior art in actual use, drainage water transmitting ability is poor, and water flow is less, usually causes self-priming pump load to increase the weight of, the problem that energy consumption is larger, save cost of production, improve manufacturing efficiency, reduce the energy consumption in production process.
Description
Technical field:
The utility model relates to pump valve field, is specifically related to a kind of impeller for self-priming pump.
Background technique:
The working principle of self-priming pump is: first in pump case, fill water (or in pump case, self has water) before starting mode of pump.After starting, impeller High Rotation Speed makes the current direction volute in impeller conduit, and at this moment enter interruption-forming vacuum, make to open into water non-return flap, the air in suction pipe enters in pump, and arrives outer rim through impeller conduit.Self-priming pump extensive use, in actual use, drainage water transmitting ability is poor, and water flow is less for the self-suction pump impeller of prior art, and usually cause self-priming pump load to increase the weight of, energy consumption is larger.
Model utility content:
Technical problem to be solved in the utility model is to overcome existing technological deficiency, there is provided a kind of rational in infrastructure, drainage water transmitting ability is strong, the impeller that self-priming pump energy consumption is low, solves the self-suction pump impeller of prior art in actual use, and drainage water transmitting ability is poor, water flow is less, usually cause self-priming pump load to increase the weight of, the problem that energy consumption is larger, save cost of production, improve manufacturing efficiency, reduce the energy consumption in production process.
Technical problem to be solved in the utility model adopts following technological scheme to realize:
For an impeller for self-priming pump, be stainless steel integral type precision casting, comprise connecting bottom board and blade, described blade is fixed on the side of connecting bottom board, it is characterized in that:
Described connecting bottom board is round structure, is provided with the attachment hole through connecting bottom board itself, is connected and fixed, is rotated by motor driven impeller by the motor shaft of attachment hole and self-priming pump itself.
Inside described attachment hole, fixed card slot is set, is fixed by fixed card slot and motor shaft, avoid connecting bottom board to be thrown out of in rotation process.
Described connecting bottom board side arranges multiple guiding gutter, guides current into self-priming pump inside by guiding gutter.
Described blade ring around being arranged on outside attachment hole, and is fixed as one with connecting bottom board.
Described blade arranges multiple, at least arranges 4.
The side of described blade both sides arranges flow guide recesses, forms drainage channel, be convenient to guide current into self-priming pump inside between two adjacent flow guide recesses, thus reduces the energy consumption of self-priming pump further.
The beneficial effects of the utility model are, there is provided a kind of rational in infrastructure, drainage water transmitting ability is strong, the impeller that self-priming pump energy consumption is low, solves the self-suction pump impeller of prior art in actual use, and drainage water transmitting ability is poor, water flow is less, usually cause self-priming pump load to increase the weight of, the problem that energy consumption is larger, save cost of production, improve manufacturing efficiency, reduce the energy consumption in production process.
Accompanying drawing illustrates:
Fig. 1 is structural representation of the present utility model.
Embodiment:
The technological means realized to make the utility model, creation characteristic, reaching object and effect is easy to understand, below in conjunction with concrete diagram, setting forth the utility model further.
As shown in Figure 1, a kind of impeller for self-priming pump, be stainless steel integral type precision casting, comprise connecting bottom board 1 and blade 2, described blade 2 is fixed on the side of connecting bottom board 1, it is characterized in that:
Described connecting bottom board 1 is round structure, is provided with the attachment hole 11 through connecting bottom board 1 itself.
Inside described attachment hole 11, fixed card slot 111 is set.
Described connecting bottom board 1 side arranges multiple guiding gutter 12.
Described blade 2 around being arranged on outside attachment hole 11, and is fixed as one with connecting bottom board 1.
Described blade 2 arranges 4.
The side of described blade 2 both sides arranges flow guide recesses 21, forms drainage channel between two adjacent flow guide recesses 21.
The utility model is used for self-priming pump, by the impeller that the utility model provides, solve the self-suction pump impeller of prior art in actual use, drainage water transmitting ability is poor, and water flow is less, usually causes self-priming pump load to increase the weight of, the problem that energy consumption is larger, save cost of production, improve manufacturing efficiency, reduce the energy consumption in production process.
More than show and describe basic principle of the present utility model and major character and advantage of the present utility model.The technician of the industry should understand; the utility model is not restricted to the described embodiments; what describe in above-described embodiment and specification just illustrates principle of the present utility model; under the prerequisite not departing from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
