Description
Technical field
The present invention relates to a kind of water pump, belong to mechanical equipment technical field.
Background technique
Water pump is the machinery of carrying liquid or making liquid supercharging.By the pump shaft impeller of prime mover, rotate liquid is done work, liquid energy is increased, rely on this energy that liquid is transported to appointed place.During water pump operation, impeller is done 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 continuously from pump outlet, be discharged from 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 during use.In During Process of Long-term Operation, each parts joint of unit can cause motor to burn out when easily infiltration is serious.
Summary of the invention
The above-mentioned technical problem that the present invention is directed to prior art, proposes a kind of obturation effect good, stable submersible pump.
The present invention is that the technological scheme that solves the problems of the technologies described above proposition is: a kind of submersible pump, is characterized in that: comprise motor casing, lid, the pump housing, motor, impeller, switch and power line; Motor is positioned at motor casing, and airtight top and the joint that is connected to motor casing of lid is provided with the first seal ring, and lid is provided with wire outlet and air nail, and power line is airtight to be fixed in wire outlet; The pump housing is fixedly connected on described motor casing bottom and joint is provided with the second seal ring, the pump housing comprises the connecting passage of the described water-inlet cavity of water-inlet cavity, water chamber and connection and water chamber, the bottom of described water-inlet cavity offers water intake, the top of described water chamber offers water outlet, pump housing bottom is also provided with sealing gasket, in the pump housing, be provided with stator, stator extends to water outlet from water intake; The bottom of motor casing is also provided with split washer, bearing and two outside framework oil seals, and motor shaft bottom, successively through split washer, bearing, outside framework oil seal and motor casing, 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: the sectional area of described connecting passage is less than the sectional area of water intake, and the sectional area of described water outlet is greater than the sectional area of water intake.
To being improved to of technique scheme: the ratio of the sectional area of described connecting passage and the sectional area of water intake is 1: 5 to 1: 3.
To being improved to of technique scheme: described wire outlet place is provided with switch.
To being improved to of technique scheme: described lid top is also provided with carrying handle.
The invention has the beneficial effects as follows: each parts joint of shell is all provided with seal ring, motor shaft bottom is also provided with outside framework oil seal, and pump housing bottom is also provided with sealing gasket; Thereby reach good obturation effect, water pump operation is stable.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the invention will be further described.
Fig. 1 is that the structure of the embodiment of the present invention is partly cutd open figure.
