Abstract

The utility model relates to an impeller and particularly to a spiral impeller. The spiral impeller comprises an annular base plate, wherein the end port of the inner wall of the base plate is provided with a barrel which protrudes upwards and has the inner diameter as same as that of the base plate; multiple circular arc impeller vanes for protruding upwards are arranged around the barrel; a gap is remained between the barrel and each impeller vane; the impeller vanes are uniformly arranged around the barrel; and the inner wall of the barrel is provided with a groove matching with a transmission shaft. As the barrel with six circular arc impeller vanes uniformly arranged at the circumference thereof is adopted, the spiral impeller, disclosed by the utility model, has the advantages of longer service life and higher use efficiency.

Description

Screw impeller
Technical field
The utility model relates to a kind of impeller, especially a kind of screw impeller.
Background technique
Development along with industry and agricultural, the increasing local submersible pump that needs to use, and bring into play this extremely important effect as the important impeller in submersible pump the inside, common impeller on the market mostly is blade impellers, although simple in structure, easily manufactured, be easy to clean foreign material and maintenance impeller, but after long-time the use, particulate contamination can make blade impaired, thereby lowers efficiency.
The model utility content
The technical problems to be solved in the utility model is: for solving the problem of above-mentioned existence, provide a kind of screw impeller, solve impeller easy impaired problem of blade after long-time the use.
The technological scheme that its technical problem that solves the utility model adopts is: a kind of screw impeller, comprise annular bottom plate, offer the cylindrical shell identical with the base plate internal diameter that raise up on the plate inner wall port, be provided with the wheel blade that a plurality of circular arcs raise up around the cylindrical shell.
In order to prevent accumulating foreign material after long-time the use, leave the gap between cylindrical shell and the wheel blade.
In order to improve the rotation efficiency of impeller, wheel blade evenly is arranged in around the cylindrical shell.
In order to make impeller can not cause because of the High Rotation Speed of transmission shaft skidding, offer the groove that cooperates for transmission shaft on the cylinder inboard wall.
The beneficial effects of the utility model are, screw impeller of the present utility model adopts six the circular arc wheel blades that evenly distribute around the cylindrical shell, make the longer service life of impeller, and utilization efficiency is higher.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is structural representation of the present utility model.
1. base plates among the figure, 2. cylindrical shell, 3. wheel blade, 4. groove.
Embodiment
By reference to the accompanying drawings the utility model is described in further detail now.These accompanying drawings are the schematic diagram of simplification, basic structure of the present utility model only is described in a schematic way, so it only show the formation relevant with the utility model.
A kind of screw impeller as shown in Figure 1 comprises annular bottom plate 1, offers the cylindrical shell 2 identical with base plate 1 internal diameter that raise up on base plate 1 inner wall port, is provided with the wheel blade 3 that six circular arcs raise up around the cylindrical shell 2.
In order to prevent accumulating foreign material after long-time the use, leave the gap between cylindrical shell 2 and the wheel blade 3.
In order to improve the rotation efficiency of impeller, wheel blade 3 evenly is arranged in around the cylindrical shell 2.
In order to make impeller can not cause because of the High Rotation Speed of transmission shaft skidding, offer for the groove 4 that cooperates with transmission shaft on cylindrical shell 2 inwalls.
Take above-mentioned foundation desirable embodiment of the present utility model as enlightenment, by above-mentioned description, the relevant staff can in the scope that does not depart from this model utility technological thought, carry out various change and modification fully.The technical scope of this model utility is not limited to the content on the specification, must determine its technical scope according to the claim scope.
