For solving the problems of the technologies described above, the technological scheme that the utility model adopted is: a kind of slag stock pump, comprise carriage, the bracket support pump housing, the pump housing comprises impeller, main shaft and pump case, pump case is fixed on the carriage front end, carriage is by the rotary pair supports main shaft, the front-end of spindle assembling is arranged on the impeller of pump case inner chamber, terminal by coupling connection motor, described pump case comprises suction chamber, one-level pump case and secondary pump case, the three is the cylinder type housing, its end face head and the tail connect successively, the one-level impeller is set in the one-level pump case, in the secondary pump case sencond stage impeller is set, one, sencond stage impeller is installed relatively, and the suction chamber sidewall is offered material feeding mouth, the suction chamber terminal surface is axially established the suction chamber outlet, the suction chamber outlet is communicated with the one-level pump case import that is opened in one-level pump case front-end face, one-level pump case sidewall is provided with the outlet of one-level pump case, and the outlet of one-level pump case is communicated with the secondary pump case import that is arranged on secondary pump case exterior edge face by connecting tube, and the sidewall of secondary pump case is offered discharge port;
Described suction chamber front end is provided with shaft sealing, and described shaft sealing comprises the axle sleeve that cooperates with main shaft, and sleeve outer surface cooperates two outside framework oil seals, and the space between two outside framework oil seals is a seal ring, stores lubricating grease, the stuffing box packing of outside framework oil seal arranged outside in the seal ring.
Further improvement of the utility model is:
Described one-level pump case Way out is provided with along one-level pump house wall tangent direction, and the outlet of one-level pump case connects pipe.
The blade face of described impeller is designed to distorted shape.
Because the technological progress of having adopted technique scheme, the utility model to obtain is:
The utility model suction chamber, one-level pump case and secondary pump case head and the tail are connected successively, and the I and II impeller is installed relatively, makes suction chamber form relative negative pressure when impeller is worked, and makes the axial seal of water pump easier.
Drip ring and two filled multi-sealed forms of outside framework oil seal are adopted in shaft sealing, make axial sealing effect better.
One-level pump case Way out is provided with along the pump house wall tangent direction, and the outlet of one-level pump case connects pipe,
The water conservancy characteristic that meets fluid has reduced fluid at the endoceliac resistance of pump, the favourable air horsepower that reduces.
The blade face of impeller is designed to twist the blade face, and resistance, energy saving in the time of can reducing fluid by impeller are raised the efficiency.
