Embodiment Construction

[0010] Such as figure 1 It is a schematic diagram of the structure of the present invention. A new type of submersible thruster impeller includes a blade 1 and a hub 2. The blade 1 and the hub 2 are integrally cast as a whole. There are two blades 1, which are symmetrical about the hub 2. The blade 1 is provided with a guide Flow slot 3. The guide grooves 3 are arc-shaped and evenly distributed on the surface of the blade 1. An arc-shaped guide groove 3 that conforms to the curve of the blade 1 is provided on the surface of the blade 1, which can guide the water flow when the blade 1 rotates and push the flow, reduce the flow split, and increase the force, thereby greatly improving the efficiency of the flow.

Abstract

The invention relates to the technical field of sewage treatment equipment and in particular relates to a novel submersible water impeller blade wheel. The novel submersible water impeller blade wheel comprises blades and a wheel hub, wherein the blades and the wheel hub are overall cast to form an integrated structure; two blades are symmetric about the wheel hub; diversion trenches are formed in the blades. The arc diversion trenches adaptive to the curved surfaces of the blades are formed in the surfaces of the blades, so that an effect of diverting water flow can be achieved when the blades rotate to implement impelling, bypass flow can be reduced, the acting force is enhanced, and the impelling efficiency is greatly improved.

Description

Technical field [0001] The invention relates to the technical field of sewage treatment equipment, in particular to a new type of submersible thruster impeller. Background technique [0002] The basic composition of the low-speed submersible thruster is: the submersible motor reaches the set output speed through the reducer, and the output shaft of the reducer is equipped with a pusher impeller. In the working state, the impeller rotates at a uniform speed, and the movement of the two blades on the impeller will be The water body is forcibly divided into an inverted cone, so the pressure difference between the front and back of the water body is established, and the water body advances to realize the equipment function. The existing thruster is a plug-in type, that is, two wing blades are inserted into a hub. This structure is used for a long time. It will affect the inclination angle of the blades and reduce the thrust effect. Moreover, if the hub is too large, it will destroy t...
