Equipped with impeller shaft hole and impeller shaft hole is through cover board, and the impeller shaft hole side is fixedly connected with support plate, the support plate one
Side offers diversion trench, and the impeller shaft hole inner wall surface offers limiting slot, and one side surface of the cover board is fixedly connected with set
Cylinder, described sleeve one end offers jack and jack runs through sleeve, and the jack side has been fixedly connected with reinforcing plate.
Further, another side surface of the cover board is fixedly connected with blade, and the blade is evenly distributed on lid surface
On.
Further, described impeller shaft hole one end is fixedly connected with flange and flange protrudes from lid surface, the flange
Diameter is slightly less than impeller shaft hole diameter.
Further, the reinforcing plate side is fixedly connected with convex block.
Compared with prior art, the present invention has the advantages that：
1. by being fixedly connected with support plate in blade and cover board junction, since two-phase flow pump needs to extract mud, and mud
A large amount of handstone can be adulterated in slurry, damage can be caused even to deform to blade, it can effective reinforced blade by support plate
Structural strength.
It 2. by being provided with diversion trench in blade surface, can effectively accelerate the flow velocity of mud, can also reduce blade in mud
The resistance rotated in slurry effectively can be such that cover board is docked with motor by being fixedly connected with sleeve in one side surface of cover board,
And offer jack in sleeve one end, in sleeve with when motor shaft is combined, sleeve passed through with pin, can to motor shaft into
Row is fixed, and effectively can be prevented cover board from generating displacement on motor shaft, be improved job stability.
3. by being fixedly connected with reinforcing plate in sleeve and cover board junction, the torsion of sleeve can be effectively improved, is passed through
It is fixedly connected with convex block in another side surface of cover board, the anti-friction power of cover board can be improved, extend its service life.
