Described sub-propeller is arranged between rear backplate and the rear pump cover.Described pump shaft is connected with the pump housing by axle sleeve.Described sub-propeller and pump shaft are affixed, in the axle sleeve arranged outside of pump shaft Packing seat are arranged, and described Packing seat is connected with lubricating cup; The described axle sleeve outside is provided with Gland with Packing seat tip butt, and described Gland is affixed by bolt and rear pump cover.The described axle sleeve outside also is provided with seal cage.The end of described pump shaft lacks column structure for ease of the circle that connects fast drive motor.Described rear pump cover lower end is provided with the positioning plate of being convenient to connect front pump cover.
The beneficial effects of the utility model:
1, the performance range of the utility model slag stock pump is wide, cavitation performance good, efficient is high, loss is few.
2, the utility model slag stock pump so that pump under best industrial and mineral, move, long service life, on-road efficiency is high, can satisfy the abominable transport condition of multiclass.
3, the operational efficiency of the utility model slag stock pump is very high, and flow passage components are relatively long working life, save production cost.
4, the stable operation of the utility model slag stock pump can not affect because of the running problem of pump the work of whole industrial and mineral system.
