Abstract
The utility model relates to a multi-stage multi-outlet centrifugal pump, which is composed of a pump housing 13, a water inlet 3, an impeller 2, a radial guide vane 7, a water outlet 12, a pump shaft 1, the front bearing body member 14 of the pump, and the back bearing body member 15 of the pump. The utility model is characterized in that every stage pump is provided with the water outlet 12. The structure of a back blade is used for balancing the axial force of the rotor of the multi-stage centrifugalpump. The structure of the utility model is novel, the safe operation of the pump can be ensured, and simultaneously, the fire spraying with different height for a high building or the requirement of the life water feeding can be satisfied.
Description
The utility model relates to a kind of multistage multiple exit centrifugal pump, is mainly used in the plumbing in high building fire fighting spray, domestic water and city, mine.
Multistage centrifugal pump in the market is single outlet pump, and Balance disc or balancing drum are set behind impeller, and with balancing axial thrust, its shortcoming is: single outlet pump can not satisfy the needs of different floor height fire-fightings of tall building and domestic water; Balance disc or balancing drum easily kill or heavy wear after the disequilibrium effect, influence the safe operation of pump.
The purpose of the utility model provides a kind of multistage multiple exit centrifugal pump, and axial force balance adopts back vane structure, and residual axial force supports with angular contact ball bearing, can guarantee the safe operation of multi-stage fire pump.
In order to realize above-mentioned purpose, the utility model is by pump case 13, water intake 3, impeller 2, back blade 9, radially fore bearing body component 14, the rear bearing body component 15 of stator 7, water outlet 12, pump shaft 1 and pump are formed, one water outlet 12 all is set in every grade of stage casing, one back blade 9 is set at the back of every grade of impeller 2, the rotation of back blade 9 force fluids, reduce the back pressure of impeller 2, reach the purpose of balancing axial thrust.
The utlity model has novel structure, characteristics safe and reliable to operation, adopt single suction multiple exit structure, can satisfy the needs of different floor height fire-fighting sprayings of tall building or domestic water.
Now in conjunction with the accompanying drawings and embodiments the utility model is described as follows:
Fig. 1 is the utility model External view;
Fig. 2 is the utility model cut-away view.
The utility model is by pump case 13, water intake 3, impeller 2, back blade 9, radially fore bearing body component 14, the rear bearing body component 15 of stator 7, water outlet 12, pump shaft 1 and pump are formed, the fore bearing body component 14 of pump is connected with pump case 13 by bolt with rear bearing body component 15, impeller 2 is fixed on the pump shaft 1 by key 10, the back of impeller 2 is provided with back blade 9, angular contact ball bearing 16 respectively is installed in the forward and backward bearing body part 14,15, radially stator 7 is connected with pump case 13 by pin 11, and piece housing all is provided with a water outlet 12 in every grade.
Prime mover is by epitrochanterian impeller 2 rotations of coupling parts 17 driven pumps, with water in water intake 3 suction pump suction chambers 4, enter the suction port 5 of impeller 2, blade 6 force fluids rotation in the impeller 2, liquid under action of centrifugal force to around throw away, enter radially stator 7, radially the return guide vane 8 on the stator 7 inserts the liquid into the suction port of next stage impeller, and liquid can be transported to high-rise each flooring with water by the water outlet 12 of piece housing in every grade.
