Description
Technical field
The utility model is related to pump technical field of diving under water, more particularly, to a kind of novel sectional multilevel 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.In order to obtain higher lift, one
As using setting multi-stage impeller and diversion component on pump shaft, but Multiple Sinking Pump operation currently on the market is not steady enough, knot
Structure is further improved.
Invention content
The purpose of this utility model is to provide a kind of novel sectional multilevel well immersible pump, using multisection type multi-stage impeller
Cascaded structure, compact-sized, lift is high, and circulation is good, safe and reliable to operation.
The technical solution of the utility model is：A kind of novel sectional multilevel well immersible pump, including water inlet joint, casing
Cover, extrudes shell, water exit end and pump shaft, and the pump shaft is equipped with multi-stage impeller structure, passes through axis in the middle part of the multi-stage impeller structure
Watt stent is divided into two sections, and bearing shell is provided on the bearing shell stent, and suit extrudes shell on the end pump shaft of multi-stage impeller structure,
The blade wheel structure includes leading shell and is installed in the impeller led in shell, and impeller is connect by clamp spring and tabletting with pump shaft, after pump shaft
End is fixedly connected across water inlet joint through shaft coupling with motor shaft.
Further, adjacent lead is sealed by dual O-ring seal between shell in each section of multi-stage impeller structure, bearing shell stent
And it is sealed positioned at leading for its both sides also by dual O-ring seal between shell.
Further, water inlet is connected in the water inlet joint, water outlet is connected on the water exit end.
The utility model has the advantages and positive effects of：
1st, immersible pump uses segmentation structure, and lift is high, and circulation is good, convenient for disassembly and assembly, safe and reliable to operation；
2nd, space is greatly saved, and multi-stage impeller structural portion dress is flexibly adjustable in multi-stage impeller segmented cascaded structure, can
Impeller quantity is adjusted according to user demand, but very high integrity is compact-sized, improves conservancy property, can meet user not
Flow together, lift need；
3rd, pump is coaxial with motor integral, improves the concentricity of rotor block, and loss when reducing pump operating to axis extends
The service life of immersible pump；
4th, it is sealed at the static seal of immersible pump using dual O-ring, ensure that the good sealing performance of immersible pump.

Specific embodiment
It elaborates below in conjunction with the accompanying drawings to the utility model.
As shown in Figs. 1-2, a kind of novel sectional multilevel well immersible pump of the utility model, including water inlet joint 1, casing cover
2, shell 3, water exit end 4 and pump shaft 5 are extruded, the pump shaft 5 is equipped with multi-stage impeller structure, passes through in the middle part of the multi-stage impeller structure
Bearing shell stent 6 is divided into two sections, and bearing shell 7 is provided on the bearing shell stent 6, is set on the end pump shaft 5 of multi-stage impeller structure
Have and extrude shell 3, the blade wheel structure includes leading shell 8 and is installed in the impeller 9 led in shell 8, and impeller 9 passes through clamp spring 10 and tabletting 11
It is connect with pump shaft 5, adjacent lead is sealed by dual O-ring seal 12 between shell 8 in each section of multi-stage impeller structure, bearing shell stent 6
And sealed positioned at leading for its both sides also by dual O-ring seal 12 between shell 8,5 rear end of pump shaft passes through water inlet joint 1 through shaft coupling 13
It is fixedly connected with motor shaft, water inlet 14 is connected in the water inlet joint 1, water outlet 15 is connected on the water exit end 4.
The course of work of this example：The pump housing is entered through water inlet joint 1 by conveying liquid, is constantly pressurizeed by multi-stage impeller structure
It is discharged afterwards from water exit end 4, lift is adjusted, and water exit end 4 can directly be connect with pipeline portions, convenient to use.
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.
