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.
In actual life, a lot of situations need to be carried sewage, and sewage bottom is conventionally piled up and had mud, and the water intake of submersible pump is usually located at pump housing bottom, so water intake is easily stopped up by mud.
Model utility content
The utility model, for the above-mentioned technical problem of prior art, proposes a kind of pump housing and is provided with leg, the not susceptible to plugging heavy sewage pump with leg of water intake.
The utility model is that the technological scheme that solves the problems of the technologies described above proposition is: a kind of heavy sewage pump with leg, comprises motor casing, lid, pump cover, the pump housing, motor, impeller, switch and power line; Motor is positioned at described motor casing, the two ends of motor casing are provided with bearing, the outer ring of bearing is fixedly connected on motor casing, bearing and the inner ring drive fit with bearing are passed in the two ends of motor shaft, the airtight top that is connected to motor casing of lid, lid is provided with wire outlet and air nail, power line is fixed in wire outlet by power line black box is airtight, pump cover is sheathed and be fixedly connected on the bottom of motor casing by screw, the pump housing is airtight to be 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, motor shaft bottom is successively through bearing, outside framework oil seal, motor casing and pump cover, stretch in the pump housing, impeller is sheathed to be fixed on motor shaft bottom and to be positioned at the pump housing, wire outlet place is provided with switch, pump housing bottom is also provided with leg, and lid top is also provided with carrying handle.
To being improved to of technique scheme: described power line black box comprises gland nut, pad and seal ring; Wire outlet inwall is provided with internal thread, the end of power line is stretched in wire outlet through gland nut, 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.
To being improved to of technique scheme: described impeller height and described pump housing aspect ratio are 1: 3 to 1: 2.
To being improved to of technique scheme: described wire outlet place is provided with switch.
The beneficial effects of the utility model are: because pump housing bottom is provided with leg, make whole water pump can stand on mud and make the pump housing away from mud, thereby water intake is not stopped up by mud.
Brief description of the drawings
Below in conjunction with accompanying drawing, the utility model is described in further detail.
Fig. 1 is the utility model embodiment's structure sectional view.
Fig. 2 is the structural drawing of the utility model embodiment's power line black box.
