Abstract

A submerged double-suction sewage pump structure is composed of a motor assembly, a bearing base, a pump cover, a pump body and a double-suction impeller. Conveyed liquid enters the double-suction impeller from a right-cone-shaped suction chamber and a semi-spiral-shaped suction chamber, and is discharged out of a discharging port of the pump body after being pressurized. The double-suction impeller can automatically balance axial force produced when a water pump operates, the service life of a bearing is prolonged, and operation reliability of the water pump is improved.

Description

A kind of diving double suction pollution discharge pump structure
Technical field
The utility model relates to a kind of diving double suction pollution discharge pump structure, is specially adapted to large flow, the pollution discharge pump that high-lift, low water level is carried.
Background technique
At present, conventional sewage pump is all structurally to adopt single suction impeller, has flow little, and the feature such as lift is low, and axial force is large, far can not meet the demand of market to large flow high-lift sewage pump.
Summary of the invention
In order to overcome the excessive and cisco unity malfunction of excessive axial force that submerged sewage pump produces in large flow, high-lift working zone, the required water level of working is higher.The utility model provides a kind of diving double suction pollution discharge pump structure, this submerged sewage pump in the time of large flow, the operation of high-lift working zone, the axial force can autobalance pump operation producing, and can realize compared with low water level and can normally work.
The utility model solves the technological scheme that its technical problem adopts: liquid enters the pump housing from axial end, part liquid enters impeller through right cone type suction chamber, another part liquid enters impeller through semi-spiral suction chamber, make to carry liquid to enter impeller from upper and lower both direction, impeller adopts double-sucking type, in impeller, mix after pressurization, discharge from the water outlet of pump housing side, the liquid sucking from semispiral type suction chamber is under the effect of impeller, produce an axial force F 1 left, the liquid sucking from the capable suction chamber of right cone, through the effect of impeller, can produce an axial force F 2 to the right, due to the symmetrical configuration of double-entry impeller, therefore, two axial force F 1 that produce, F2 is equal and opposite in direction, the power of opposite direction, axial force automatic balancing, in addition due to suction port below, having realized ultra low water level pump also can normally work.
The beneficial effects of the utility model are, have improved submerged sewage pump reliability of operation, have expanded working zone, have realized ultra low water level and have normally worked.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is further illustrated.
1. double-entry impellers in figure, the 2. pump housing, 3. pump cover, 4. bearing support, 5. electric machine assembly, 6. impeller nut, 7. semispiral type suction chamber, 8 right cone type suction chambers.
Embodiment
In Fig. 1, bearing support (4) and electric machine assembly (5) are connected, pack into successively pump cover (3), impeller (1), get rid of tightly with impeller nut (6), the last same pump housing (2) connects, when work, liquid enters in the double-entry impeller (1) of High Rotation Speed from right cone type suction chamber (8) and semispiral type suction chamber (7), and liquid enters impeller, obtain after energy, discharge from pump housing side outlet.The axial force F 1 that the liquid entering from semispiral type suction chamber produces, with the axial force F 2 that the liquid from right cone type suction chamber produces, equal and opposite in direction, opposite direction, balance mutually, the working life of improving motor bearings, in addition due to suction port below, realized ultra low water level pump and also can normally work.

Claims (2)

1. a diving double suction pollution discharge pump structure, it is characterized in that: after bearing support connects with electric machine assembly, load onto pump cover, impeller in connection, gets rid of impeller tightly with impeller nut, and liquid enters the pump housing from axial end, part liquid enters impeller through right cone type suction chamber, another part liquid enters impeller through semi-spiral suction chamber, through impeller pressurization, discharges from pump housing side outlet.
2. diving double suction pollution discharge pump structure according to claim 1, is characterized in that: electric machine assembly connects with the pump housing after being connected with bearing support, pump cover, impeller.
