Abstract
The utility model provides an impeller. The impeller comprises an impeller main body and an air outlet passage, wherein the air outlet passage is communicated with the inner part of the impeller main body, a plurality of air inlet parts are opened in the impeller main body, each air inlet part comprises multiple air inlet passages, and the inner walls of the air inlet passages are in a shape of an arc line; one end of each of the air inlet passages is served as an air suction end, and the other end of each of the air inlet passages is served as an air outlet end, and the air outlet end is communicated with the air inlet passage. In comparison with the conventional impeller, a multilayer air inlet passage of the design increases an air suction port and the medium processing amount, the volume is small, and no leakage is generated, and the working efficiency is improved.
Description
Technical field
The utility model relates to exhaust or draining process field, is specifically related to a kind of parts of air thrust.
Background technique
At present, rely on the equipment of promotion air or water acting a lot, such as equipment such as blower or pump classes, rely on wheel rotation to produce certain thrust or pressure, the kind of impeller is a lot, and the impeller matching is therewith also varied.More common impeller has the forms such as the air-breathing or propeller of individual layer, and gettering quantity is less, and volume ratio is larger, after common impeller reaches certain pressure or temperature, is easy to will produce modification or fracture, and noise is high, and inefficiency.
Model utility content
The purpose of this utility model is to provide impeller, solves one or more in above-mentioned prior art problem.
According to an aspect of the present utility model, the impeller providing, comprises impeller body and outlet passageway, outlet passageway and impeller body internal communication, in impeller body, offer multilayer air input part, every layer of air input part comprises multiple gas-entered passageways, and the madial wall of gas-entered passageway is arc shaped; Gas-entered passageway one end is suction end, and the other end is outlet side, and outlet side is communicated with described outlet passageway.This design have a multilayer gas-entered passageway, relatively existing impeller, has strengthened air-breathing port, has increased the total amount for the treatment of media, volume is little, without leaking, has improved working efficiency.
According to an aspect of the present utility model, gas-entered passageway entirety progressively raises up, and the upper end of outlet side and outlet passageway seamlessly transits.Make gas-entered passageway become a bend, and bend is tangent therewith to make outlet passageway as far as possible, forms a complete and level and smooth air by bend with this, reduced air flow resistance and loss, flow passage structure makes it firmer, not flexible type or damage.
According to an aspect of the present utility model, the upper-end inner diameter of outlet passageway is greater than bottom diameter.The upper end of outlet passageway is one end of giving vent to anger of gas, the increasing smooth outflow that contributes to gas of internal diameter of outlet passageway, the loss of further having avoided gaseous exchange to produce.
Accompanying drawing explanation
Fig. 1 is the schematic perspective view of a kind of mode of execution of the present utility model;
Fig. 2 is the plan view of a kind of mode of execution of the present utility model;
Fig. 3 is the A-A sectional view in Fig. 2;
Fig. 4 is the B-B sectional view in Fig. 2.
Embodiment
Below in conjunction with Figure of description, the utility model is described in more detail.
As shown in Figure 1, the impeller that the utility model provides, comprises impeller body 1 and outlet passageway 2, and outlet passageway 2 is vertically through impeller body 1; In impeller body 1, offer multilayer air input part, every layer of air input part comprises multiple gas-entered passageways 11, and the madial wall of gas-entered passageway 11 is arc shaped; Gas-entered passageway 11 one end are suction ends, and the other end is outlet side, and outlet side is communicated with outlet passageway 2.Wherein, impeller body 1 is in the form of annular discs, and outlet passageway 2 and impeller body 1 are one-body molded.In every layer of air input part, all have multiple gas-entered passageways 11, between the plurality of gas-entered passageway 11, have sidewall to separate.Gas-entered passageway 11 between each layer has roof to separate.It is to be convenient to and the seamlessly transitting of outlet passageway 2 that the madial wall of gas-entered passageway 11 is arc shaped, being convenient to gas enters after gas-entered passageway 11 from the suction end of gas-entered passageway 11, enter outlet passageway 2 from the outlet side of gas-entered passageway 11 reposefully, reduce the loss of gas, improve the working efficiency of air compressing.
In addition, gas-entered passageway 11 entirety progressively raise up, and the upper end of outlet side and outlet passageway 2 seamlessly transits.It should be noted that, this is the another improvement for further being avoided the loss of gas in the time that gas-entered passageway 11 enters outlet passageway 2.The entirety of gas-entered passageway 11 herein progressively raises up, and object is to make gas-entered passageway 11 to become a bend, and make outlet passageway 2 bend is tangent therewith as far as possible, forms a complete and level and smooth air pass through bend with this.
The upper-end inner diameter of outlet passageway 2 is greater than bottom diameter, and the upper end of outlet passageway 2 is one end of giving vent to anger of gas, and the increasing smooth outflow that contributes to gas of internal diameter of outlet passageway 2, has further avoided convection loss in gas communication.
More than statement is only optimal way of the present utility model; it should be pointed out that to those skilled in the art, do not departing under the prerequisite of the utility model creation design; can also make some distortion and improvement, within these also should be considered as protection domain of the present utility model.
