The sewage submersible pump is good in sealing effect and stable in running.
Description
Technical field
The present invention relates to a kind of water pump, belong to mechanical equipment technical field.
Background technique
Water pump is conveying liquid or the machinery making fluid pressurization.Rotated liquid acting by the pump shaft impeller of prime mover, liquid energy is increased, relies on this energy by Liquid transfer to appointed place.During water pump operation, impeller does high speed rotating motion in the pump housing, liquid in the pump housing is along with the rotation of one piece, impeller, liquid is thrown away by impeller at water outlet under the influence of centrifugal force, the liquid thrown away speed in pump housing explosion chamber is slack-off gradually, and after liquid is thrown out of, impeller central place forms vacuum low-pressure district, liquid in liquid pool, under the atmospheric effect in the external world, flows in water pump through water inlet.Liquid is continuously sucked up like this and is then continuously discharged from pump outlet again from liquid pool.
Submersible pump is the visual plant of deep-well water lift, and during use, whole unit pulls the plug work.In During Process of Long-term Operation, easily seep water and cause motor to burn out in each parts joint of unit.
Summary of the invention
The present invention is directed to the above-mentioned technical problem of prior art, propose a kind of obturation effect good, stable sewage submersible pump.
The present invention is the technological scheme solving the problems of the technologies described above proposition: 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, lid is airtight is connected to the top of motor casing and joint 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, second seal ring is bottom wire outlet and between power cord ends, pad is between power cord ends and the bottom of gland nut, gland nut screws in wire outlet, thus is pressed abd fixed in wire outlet by power cord ends; Pump cover is sheathed and be airtightly connected to the bottom of motor casing and joint is provided with the 3rd seal ring, and the pump housing is fixedly connected on pump cover, is provided with water intake side and is provided with water outlet bottom the pump housing; The bottom of motor casing is also provided with two outside framework oil seals, and successively through bearing, outside framework oil seal, motor casing and pump cover bottom motor shaft, stretch in the pump housing, impeller is sheathed to be fixed on motor shaft bottom and to be positioned at the pump housing.
Being improved to technique scheme: described wire outlet place is provided with switch.
Being improved to technique scheme: be also provided with leg bottom the described pump housing, 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, is also provided with outside framework oil seal bottom motor shaft, and power line and connection jaws joint are also provided with gland nut, and power line not easily loosens; Thus reaching good obturation effect, water pump operation is stablized.
