Abstract
The utility model relates to a stirring-type discharge submersible electric pump. The defects of low efficiency, easy blockage and serious cavitation phenomenon exist in the existing discharge submersible electric pump. The utility model comprises a motor, a pump body, an impeller which is positioned in a pump cavity and is driven by a motor shaft. The motor shaft is extended to the lower side of the impeller, and is installed with an agitating wheel. The utility model is characterized in that an axial water inlet and a radial drainage hole which is communicated with the water inlet are provided on the agitating wheel; a chassis is provided on the lower side of the pump body; a protecting seat is provided on the position of the chassis corresponding to the agitating wheel, and a back water port corresponding to the water inlet of the agitating wheel is provided on the protecting seat; a back water channel is provided between the back water port and the high-pressure area of the pump cavity. The stirring-type discharge submersible electric pump prevents the contamination from stacking, ensures the smoothness of the water current, extends the service life, accelerates the water current velocity, and raises the pump efficiency.
Description
[technical field]
The utility model relates to a kind of pump, especially a kind of blowdown Submerged Motor Pumps that sewage dirt is had stirring action.
[background technique]
In sewage disposal process, need to use the blowdown Submerged Motor Pumps, its operating conditions is very abominable.At present, general blowdown Submerged Motor Pumps is the single drain function of tool, pump in the course of the work, the dirt in the sewage can be stacked into the ingress of pump chamber gradually, can cause the obstructed of current, influences its working efficiency.
In addition, usually be dissolved with many acid bubbles in the sewage, the intersection of these bubbles and sewage can produce acid solution, in the working procedure of pump, the parts that contact with sewage (as impeller, motor shaft) can frequently contact above-mentioned bubble, and serious cavitation phenomenon (promptly being corroded by acid solution) takes place, influence the working life of pump.
[model utility content]
In order to solve low, the easy obstruction of efficient that exists in the existing blowdown Submerged Motor Pumps, the defective that cavitation phenomenon is serious, the utility model provides a kind of stirring type blowdown Submerged Motor Pumps, and further reaches the effect of improving current.
The technological scheme that the utility model adopted is: stirring type blowdown Submerged Motor Pumps, comprise motor, the pump housing be positioned at pump chamber by the shaft-driven impeller of motor, described motor shaft extends the downside of impeller and stirring wheel is installed, and it is characterized in that the radially weep hole that described stirring wheel is provided with axial water inlet and is communicated with water intake; Downside at the described pump housing is provided with the chassis, and the position corresponding with described stirring wheel, this chassis is provided with anti-guard housing, and should offer the backwater mouth corresponding with the water intake of described stirring wheel on the anti-guard housing, is provided with backwater channel between the zone of high pressure of this backwater mouth and described pump chamber.The current of pump chamber zone of high pressure flow to backwater mouth through backwater channel, flow into stirring wheel by axial water inlet again, discharge at a high speed around weep hole radially under the effect of pressure medium in centrifugal force and pump chamber at last.Because agitator disk rotates with motor shaft, the current of discharging from weep hole radially form stirring and wash away current near the pump chamber water intake, can stir dirt, prevent its deposition, simultaneously can accelerate drainage flow, reduce the time of contact of bubble and electric pump parts, and the bubble separation that is dissolved in the sewage is gone out, reduce the air bubble content in the sewage, thereby alleviate cavitation phenomenon; Anti-guard housing can be protected motor shaft extending portion and stirring wheel, makes its proper functioning.
Backwater channel of the present utility model is opened on the chassis.Can utilize the existing parts of electric pump like this, after it is transformed, needn't add part in addition, and its position help cooperating better with stirring wheel.
The lower end of stirring wheel of the present utility model is positioned at described backwater mouth.The lower end of stirring wheel is stretched in the backwater mouth, and the current that are convenient to backwater channel enter stirring wheel, and can be better the extending portion and the stirring wheel of motor shaft be played location and protection.
Have three uniform agitators on the stirring wheel of the present utility model, described weep hole is positioned on the described agitator, and described three agitator shape settings in the shape of a spiral.Spiral helicine agitator can further strengthen stirring action, can also promote current simultaneously and enter the pump chamber inlet, accelerates the flow velocity of water, improves the efficient of pump, reduces the possibility that cavitation erosion takes place more effectively.
The beneficial effects of the utility model are: prevent dirt accumulation, guarantee that current are unobstructed, increase the service life, accelerate water velocity, improve the efficient of pump.
[description of drawings]
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the structural representation of the utility model stirring wheel.
[embodiment]
Stirring type blowdown Submerged Motor Pumps as shown in the figure, motor 1 and the pump housing 2 parts more than the pump chamber are all similar with electric pump commonly used, the pump housing 2 downsides connect chassis 7, on chassis 7, offer backwater channel 5, one end of this passage and the zone of high pressure 3 of pump chamber (are the pump chamber zone in impeller 9 outsides, because of being subjected to the impeller action of centrifugal force to form high pressure in this zone) be communicated with, the other end extends chassis 7 centre and is connected with the backwater mouth 8 that is located at chassis central authorities.
The lower ends downward of motor shaft 4 is extended the pump chamber water intake and the stirring wheel 6 that is spirally connected, and stirring wheel 6 offers water inlet 13 vertically, radially is evenly distributed with three helical agitators 10, all is provided with the weep hole 12 that is communicated with water inlet 13 on each agitator 10.
The lower end of stirring wheel 6 is stretched in the anti-guard housing 11 on the chassis 7, and backwater mouth 8 is communicated with water inlet 13.
During work, 4 while of motor shaft impeller 9 and stirring wheel 6 rotations, the current of zone of high pressure 3 flow into stirring wheels via backwater channel 5, backwater mouth 8, discharge at a high speed by weep hole 12, near the sewage the stirring pump chamber water intake, and promote the sewage upper reaches.
