Abstract
The utility model relates to a double-suction submersible sewage pump capable of realizing bi-directional water flooding, which consists of a motor part, an oil chamber, a rear pump cover, an upper water absorption tube, a pump body, a lower water absorption tube and a double-suction impeller. The delivery fluid flows into the double-suction impeller from the upper water absorption tube and the lower water absorption tube and then are pressurized to be discharged from a discharging port of the pump body. The mechanical seal contacted with the delivery fluid is positioned at the low-pressure working area, and the double-suction impeller can automatically balance the axial force generated by the running of the pump.
Description
Affiliated technical field
The utility model relates to a kind of new structure submersible pump, is specially adapted to the submersible pump of big flow, high-lift conveying.
Background technique
At present, submerged sewage pump commonly used structurally all is to adopt single suction impeller, advances the mode of branch down, and promptly the liquid of Shu Songing enters impeller from the pump bottom, through the impeller pressurization, discharges from water pump side water outlet.Two cover series connection unbalanced type mechanical seals, a cover is installed in the zone of high pressure at the impeller back side, directly contacts with carrying liquid, and a cover is installed in the grease chamber, prevents to carry liquid to enter motor, burns motor.Submerged sewage pump commonly used is because structural reason, can only select unbalanced type mechanical seal, unbalanced type mechanical seal is applicable to low pressure, otherwise wearing and tearing are accelerated, cause the improper inefficacy of mechanical seal, therefore submerged sewage pump rated lift commonly used is lower, impeller produces a downward axial force when work in addition, under same flow, lift is high more, the axial force that produces is big more, and submerged sewage pump commonly used does not have axial thrust balancing devices, and the axial force pulling rotor axial that is produced moves, contact with retaining element, cause damage parts so that can not work.And all axial force and radial forces are born by motor bearings, reduce bearing working life,
Summary of the invention
In order to overcome the problem that submerged sewage pump need bear high pressure in big flow, excessive axial force that high-lift working zone produced and mechanical seal, the utility model provides a kind of submerged sewage pump, this submerged sewage pump is when big flow, the operation of high-lift working zone, mechanical seal is in low pressure area work, and the axial force that can the autobalance pump operation produces.
The technological scheme that its technical problem that solves the utility model adopts is: pump body is connected with upper and lower two horn shape suction sleeves, make and carry liquid to enter impeller from both direction up and down, impeller adopts double-sucking type, suck liquid from above-below direction simultaneously, after in impeller, mixing pressurization, discharge from the water outlet of pump housing side.The online tool sealing of two cover string unbalanced types, a cover is installed in suction port end on the double-entry impeller, directly contacts with carrying liquid, and a cover is installed in the grease chamber.When the diving sewage water pump operation, suction eye is a low pressure area, and mechanical seal can wear out failure cause having the impurity medium to enter the grease chamber because of the pressure height, damages the second cover mechanical seal, makes and carries liquid to enter motor cavity.Impeller is in operation process, the liquid that sucks from following suction sleeve is under the effect of impeller, produce a downward axial force F 1, from the liquid that last suction port sucks, the effect of process impeller, can produce an axial force F that makes progress 2, because the symmetrical configuration of double-entry impeller, therefore, two axial force F 1, F2 being produced are equal and opposite in directions, the power that direction is opposite, axial force automatic balancing.
The beneficial effects of the utility model are, have improved the submerged sewage pump reliability of operation, have enlarged the working zone.
