Abstract
The invention relates to a heavy sewage pump. The heavy sewage pump comprises a motor casing, a box cover, a pump cover, a pump body, a motor, an impeller, a float switch and a power line. The motor is located in the motor casing, the box cover is connected to the top of the motor casing in a sealed mode through a screw, a line outlet and a pneumatic nail are arranged on the box cover, the power line is fixed into the line outlet in a sealed mode through a sealing assembly, the pump cover is arranged at the bottom of the motor casing in a sleeved mode and fixedly connected to the bottom of the motor casing through a screw, the pump body is connected to the pump cover through a screw, a water inlet is formed at the bottom of the pump body, and a water outlet is formed in one side of the pump body. Two framework oil seals are arranged at the bottom of the motor casing, the bottom of a motor shaft sequentially penetrates through bearings, the framework oil seals, the motor casing and the pump cover and stretches into the pump body, the impeller is fixed to the bottom end of the motor shaft in a sleeved mode and located in the pump body, and the ratio of the height of the impeller to the height of the pump body ranges from 1:3 to 1:2. Due to the fact that a pumping chamber of the pump body is large in space and the impeller shrinks away from a passageway of the pumping chamber, through capacity of impurities in water is good, and the pump is not prone to abrasion or blockage.
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.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 in sewage, contain the fibre object of solid particle and easy winding or pack, easily cause impeller and pump housing inner wall abrasion and impeller obstruction etc., can make pump efficiency reduce in long-time running.
Summary of the invention
The present invention is directed to the above-mentioned technical problem of prior art, propose a kind of heavy sewage pump that can carry sewage that is difficult for causing wearing and tearing and obstruction.
The present invention is that the technological scheme that solves the problems of the technologies described above proposition is: a kind of heavy sewage pump, comprises motor casing, lid, pump cover, the pump housing, motor, impeller, switch and power line; Motor is positioned at 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, lid is by the airtight top that is connected to motor casing of screw, 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 connected on pump cover by screw is airtight, 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, and impeller height and pump housing aspect ratio are 1: 3 to 1: 2.
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 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 invention has the beneficial effects as follows: because pump housing pumping chamber space is large, the passing capacity of the impurity such as solid particle and fibre object is good, and impeller contracts from pump housing pumping chamber runner, in running, impeller does not contact with impurity such as fibre object with solid particle, the situation of blade wear is lighter, is not prone to stopping state and can not causes in long-time running the problem of efficiency degradation.
Brief description of the drawings
Below in conjunction with accompanying drawing, the invention will be further described.
