Summary of the invention
The technical problems to be solved in the utility model is, a kind of leakage that do not produce is provided, and floor space is little, and the vertical slag slurry pump that the impeller clearance is adjustable is in order to overcome the defective of background technique.
Solve the problems of the technologies described above and adopt following technological scheme: a kind of vertical slag slurry pump, comprise the pump housing, impeller, back backplate, pump shaft, bearing, bearing support, bearing housing, fluid bend pipe, bearing places in the bearing housing, the pump housing is provided with the liquid inlet/outlet, and liquid entering hole is communicated with the lower end that is positioned at the pump housing with the pump housing, and liquid outlet is positioned at the end of the fluid bend pipe that is connected with the pump housing, impeller is installed on the pump shaft, and motor is connected with the pump shaft belt.Its structure outline is, a, described bearing are two cover tapered roller bearing and one group of roller bearing composite structures, a pair of tapered roller bearing is fixed in the top of pump shaft, its bearing outside is fixed on the bearing support, between bearing support and the bearing housing Spielpassung, bearing support and bearing housing with connecting bolt with adjust bolt and is connected to adjust and fixes; Roller bearing is installed in the middle part of pump shaft, is positioned at the bottom of bearing housing, and the bottom of bearing housing is fixed on the pump seat; B, impeller, the pump housing and back backplate are installed in the bottom of pump, and impeller is threaded with pump shaft, cooperates with the adjustment of liquid entering hole gap; C, the pump housing are connected with bearing housing with support tube by land.
Adopt technique scheme, this pump is a vertical structure, and floor space is 1/3 of a horizontal pump.During work, the working portion of the pump housing immerses in the liquid pool, by the sealing of the liquid in pond axle envelope, and also can proper functioning under the situation of ore pulp deficiency.This pump is with transmission with V in addition, can change wheel speed by the mode of changing belt wheel, thereby realize the adjustment to pumping head and flow, satisfies the usage requirement of different lifts and flow.Its bearing unit adopts the compound mode of double tapered bearing and roller bearing, has overcome larger axis that pump produces at work to pressure, prolongs the working life of bearing, and makes the running of pump more stable.This pump rotor part can be adjusted easily, so when impeller and the pump housing are worn, can easily the optimum position be adjusted in the impeller clearance, makes the running of pump more efficient.The impeller of this pump and the pump housing partly pass through optimal design, so this pump is energy-efficient, and long service life, easy to maintenance.
Description of drawings
Accompanying drawing 1 is the utility model overall structure schematic representation.
Below in conjunction with the drawings and the specific embodiments the utility model is further described.
Embodiment
The utility model is made up of the pump housing 1, impeller 2, back backplate 3, land 4, fluid bend pipe 5, bearing housing 8, bearing 10, pump shaft 19, support tube 20, motor 17 etc.
Referring to accompanying drawing 1, drive part of the present utility model is made up of motor 17, pump shaft 19, bearing 10,18, and motor wheel 16 usefulness V-shape belts are connected with the belt pulley 12 of pump shaft 19.The use of V-shape belt can change the rotating speed of pump by the method for changing belt pulley, realizes the adjustment to pumping head and flow.Bearing adopts a pair of tapered roller bearing 10 and roller bearing 18 fabricated structures of installing back-to-back, is positioned at bearing housing 8, and the top that a pair of tapered roller bearing 10 is fixed in pump shaft 19 is installed back-to-back, with nut and shaft locking.Its bearing outside is fixed on the bearing support 9, is connected adjustment with connecting bolt 14 and adjustment bolt 13 between the bearing support 9 and bearing housing 8 Spielpassung, bearing support 9 and bearing housing 8 and fixes.The upper end of tapered roller bearing 10 covers completely with bearing gland 11.Roller bearing 18 is installed in the middle part of pump shaft 19, is positioned at the bottom of bearing housing 8, and is fixing with jump ring and pump shaft 19, and cooperates with the bottom gap of bearing housing 8.The bottom of bearing housing 8 is fixed on the pump seat 6.This set can carry bigger axial pressure and radial pressure, makes the operation of pump more firm, and can adjust the gap of the pump impeller 2 and the pump housing 1 easily.
Impeller 2, the pump housing 1 and back backplate 3 are installed in the bottom of pump, and wherein impeller 2 is installed in the inside of the pump housing 1, is threaded with pump shaft 19, cooperates with liquid entering hole 23 gap adjustment; Liquid entering hole 23 is communicated with the lower end that is positioned at the pump housing 1 with the pump housing, liquid outlet 7 is positioned on the fluid bend pipe 5.Fluid bend pipe 5 is positioned at a side of the pump housing 1, and an end is communicated with pump housing side, and the other end is fixed on the pump seat 6, and its end is a liquid outlet 7.
