Description
Technical field
The utility model relates to a kind of water pump, belongs to mechanical equipment technical field.
Background technique
Water pump is the machinery of carrying liquid or making liquid supercharging.Rotate liquid acting by the pump shaft impeller of prime mover, liquid energy is increased, rely on this energy that liquid is transported to appointed place.When water pump operation, impeller does high speed rotating motion in the pump housing, liquid in the pump housing is along with rotation of impeller, under the effect of centrifugal force, liquid is thrown away by impeller at water outlet, the liquid throwing away speed in pump housing explosion chamber is slack-off gradually, and after liquid is thrown out of, impeller center forms vacuum low-pressure district, liquid in liquid pool is under the atmospheric effect in the external world, in water inlet flows into water pump.Then liquid continuously drunk up and be continuously discharged from from pump outlet again like this from liquid pool.
Submersible pump is the visual plant of deep-well water lift, the whole unit work that pulls the plug when use.In During Process of Long-term Operation, the each parts of unit joint easily infiltration causes motor to burn out.
Model utility content
The utility model, for the above-mentioned technical problem of prior art, proposes a kind of obturation effect good, stable sewage submersible pump.
The utility model is that the technological scheme that solves the problems of the technologies described above proposition is: a kind of sewage submersible pump, is characterized in that: comprise motor casing, lid, pump cover, the pump housing, motor, impeller, switch and power line; Motor is positioned at described motor casing, airtight top and the joint that is connected to motor casing of lid is provided with the first seal ring, lid is provided with wire outlet and air nail, power line is fixed in wire outlet by power line black box is airtight, and power line black box comprises gland nut, pad and the second seal ring; Described wire outlet inwall is provided with internal thread, the end of power line is stretched in wire outlet through gland nut, the second seal ring is between wire outlet bottom and power line end, pad is between power line end and the bottom of gland nut, gland nut screws in wire outlet, thereby power line end is pressed abd fixed in wire outlet; Sheathed and airtight bottom and the joint that is connected to motor casing of pump cover is provided with the 3rd seal ring, and the pump housing is fixedly connected on pump cover, and pump housing bottom is provided with water intake one side and is provided with water outlet; The bottom of motor casing is also provided with two outside framework oil seals, and motor shaft bottom, successively through bearing, outside framework oil seal, motor casing and pump cover, is stretched in the pump housing, and impeller is sheathed to be fixed on motor shaft bottom and to be positioned at the pump housing.
To being improved to of technique scheme: described wire outlet place is provided with switch.
To being improved to of technique scheme: described pump housing bottom is also provided with leg, and lid top is also provided with carrying handle.
The beneficial effects of the utility model are: the each parts of shell joint is all provided with seal ring, and motor shaft bottom is also provided with outside framework oil seal, and power line and connection jaws joint are also provided with gland nut, and power line is difficult for loosening; Thereby reach good obturation effect, water pump operation is stable.
Brief description of the drawings
Below in conjunction with accompanying drawing, the utility model is described in further detail.
