Description
Technical field
The utility model is related to pump technical field of diving under water, more particularly, to a kind of well immersible pump.
Background technology
Well is that motor and water pump direct-connected integrated pull the plug the water lift equipment of work with immersible pump, it is suitable for carrying from deep-well
It takes underground water, can also be used for the water lifts engineering such as river, reservoir, water channel；Multiple Sinking Pump is mainly used for field irrigation and plateau
People and animals' water in area also uses for city, factory, railway, mine, building site water supply and sewage.After turn on pump, impeller high speed rotation,
In liquid rotated together with blade, under the influence of centrifugal force, fly away from impeller and project outward, the liquid of injection expands in pump case
Scattered interior speed is gradually slack-off, and pressure gradually increases, and is then flowed out from pump discharge discharge pipe.Some existing wells are deposited with immersible pump
It is larger in internal friction, run the problems such as unstable.
Invention content
The purpose of this utility model is to provide a kind of well immersible pump, and bearing portions uses bearing shell mechanism at three, makes operation
It is more steady.
The technical solution of the utility model is：A kind of well immersible pump, including pump ontology and in the pump ontology
Pump shaft, blade wheel structure is installed in the middle part of the pump shaft, the middle part of the blade wheel structure is divided into two sections by bearing shell stent, institute
It states and the first bearing shell is provided on bearing shell stent, the both ends of the pump shaft are additionally provided with the second bearing shell and third bearing shell, and described second
The axle sleeve to match with the second bearing shell is additionally provided in bearing shell, extrusion is further sleeved on the pump shaft between the second bearing shell and blade wheel structure
Shell is connected on stent and led on the extrusion shell, and the top led on the stent is installed with stent pressing plate, the pump the tip of the axis
It is fixedly connected by shaft coupling with motor shaft.
Further, it is fixed and seals by bolt and O-ring seal between being led on the stent pressing plate and stent.
Further, water inlet joint and water exit end is also respectively connected in the both ends of the pump ontology.
The utility model has the advantages and positive effects of：
1st, bearing portions uses bearing bush structure design at three, ensure that the concentricity of impeller and motor, it is unnecessary to reduce
Friction, operation it is more steady, substantially prolong the service life of immersible pump；
2nd, the middle part of blade wheel structure is divided into two sections by bearing shell stent, and space is greatly saved in segmented cascaded structure,
It is compact-sized, it is convenient for disassembly and assembly, it ensure that good conservancy property.

Specific embodiment
It elaborates below in conjunction with the accompanying drawings to the utility model.
As shown in Figs 1-4, a kind of well immersible pump of the utility model, including pump ontology 1 and in the pump ontology 1
Pump shaft 2,2 middle part of the pump shaft is equipped with blade wheel structure 3, and the middle part of the blade wheel structure 3 is divided into two by bearing shell stent 4
Section, the first bearing shell 5 is provided on the bearing shell stent 4, the both ends of the pump shaft 2 are additionally provided with the second bearing shell 6 and third bearing shell
7, the axle sleeve 8 to match with the second bearing shell 6, the pump shaft 2 between the second bearing shell 6 and blade wheel structure 3 are additionally provided in second bearing shell 6
On be further sleeved with and extrude shell 9, be connected on stent on the extrusion shell 9 and lead 10, the top that 10 are led on the stent is installed with branch
Frame pressing plate 11 is fixed and is sealed by bolt and O-ring seal 12 between leading 10 on the stent pressing plate 11 and stent, described
The end of pump shaft 2 is fixedly connected by shaft coupling 13 with motor shaft, and water inlet joint 14 is also respectively connected in the both ends of the pump ontology 1
With water exit end 15.
The course of work of this example：Pump ontology 1 is entered through water inlet joint 14 by conveying liquid, is constantly pressurizeed by blade wheel structure
It is discharged afterwards from water exit end 15, water exit end 15 can directly be connect with pipeline portions, convenient to use；Bearing portions uses axis at three
Tile structure designs, and ensure that the concentricity of impeller and motor, reduces unnecessary friction, operation is more steady, greatly prolongs
The service life of immersible pump.
One embodiment of the utility model is described in detail above, but the content is only the utility model
Preferred embodiment, it is impossible to be construed as limiting the scope of the utility model.It is all to be made according to application scope of the utility model
All the changes and improvements etc., should all still belong within the patent covering scope of the utility model.
