The utility model is that the technical scheme that solution technical problem is used is：
A kind of stent-type Simple sealing submerged pump, including connecting tube and the pump housing, pump shaft are placed in connecting tube and the pump housing.Its
In, pump support is provided between connecting tube and the pump housing, bearing block is provided between connecting tube and pump support, rolling is provided with inside bearing block
Bearing, pump shaft passes through roller bearings；The pump support is cylindrical in shape, and offers dismounting window in its correspondence both sides；Institute
State the upper end correspondence dismounting window of pump internal stent and be provided with machine envelope around pump shaft, and the lower end of pump internal stent and around pump shaft
It is provided with packing seal.
By implementing above-mentioned technical proposal, the utility model is using pump support of the both sides with dismounting window, so that connecting
Open type design is improved between adapter and the pump housing；The pump internal stent is provided with machine envelope and packing seal simultaneously.The machine envelope
For sealing the pressure produced by liquid level difference in night pond, do not allow liquid medium to penetrate into connecting tube and Bearing inner, the pressure value compared with
Small to avoid liquid medium into the service life of bearing block internal influence bearing, described filler sealing can seal pump body
Liquid medium, even if there is a small amount of leakage, it is also possible to flow back into night pond by dismantling window, nor affect on the use of bearing
In the life-span, finally ensure that the normal operation of submerged pump.The utility model devises dismounting window, facilitates the installation of seal assembly
And safeguard, and simple structure, must even not consider that pump body pressure causes liquid to penetrate into the influence of Bearing inner to it, from
And extend the service life of submerged pump.
Used as further improvement of the utility model, the pump housing described in the technical program is provided with delivery port, and delivery port connects
It is connected to outlet pipe；Flush pipe is provided with the position of correspondence fitting machine envelope, one end and the outlet pipe of the flush pipe are connected, and the other end is worn
Cross dismounting window and extend to machine envelope.So design is advantageous in that：When machine envelope is exposed on liquid level, can be by outlet pipe
And flush pipe is sealed to machine and sprayed water, occur so as to avoid the phenomenon burnt by machine envelope frictional heat.
As another improvement of the present utility model, in the lower section of bearing block and positioned at the top of machine envelope in the technical program
Tetrafluoro oil sealing is provided with around pump shaft, sealing property is further increased.
Used as the further improvement of above-mentioned technical proposal, the sealing of described filler described in the technical program is that tetrafluoro filler is close
Envelope.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
In figure：1. connecting tube；2. the pump housing；3. pump shaft；4. impeller；5. pump support；6. bearing block；7. flush pipe；8. tetrafluoro
Oil sealing；21. delivery ports；22. outlet pipes；51. dismounting windows；52. machines are sealed；53. packing seals.
Specific embodiment
The utility model is described in further details below in conjunction with the drawings and specific embodiments.
A kind of stent-type Simple sealing submerged pump as shown in Figure 1, it mainly includes connecting tube 1, the pump housing 2 and pump shaft 3, pump shaft
3 are placed in inside connecting tube 1 and the pump housing 2, and pump shaft 3 is by bearings in connecting tube 1；Pump shaft end inside the pump housing 2 is consolidated
Surely there is impeller 4, pump shaft 3 rotarily drives impeller 4, so as to the liquid in liquid pool is detached to operation area.In the utility model, even
Pump support 5 is provided between adapter 1 and the pump housing 2, the pump support 5 is cylindrical in shape, and its correspondence both sides offers dismounting window 51,
The closed design between the pump housing 2 and connecting tube 1 is thus changed to open type design.And set between connecting tube 1 and pump support 5
There is bearing block 6, rolling bearing is provided with inside bearing block 6, pump shaft 3 passes through roller bearings.Simultaneously also inside pump support 5
Upper end correspondence dismounting window 51 and it is provided with machine envelope 52 around pump shaft 3, and lower end inside pump support 5 and being provided with around pump shaft 3 is filled out
Material sealing 53, described filler sealing 53 can use tetrafluoro packing seal.
The utility model carries the pump support 5 of dismounting window 51 using both sides, so that changing between connecting tube 1 and the pump housing 2
It is open type design to enter, while machine is provided with inside the pump support 5 seals 52 and packing seal 53.The machine envelope 52 is used for sealing fluid
The pressure produced by liquid level difference in pond, does not allow liquid medium to penetrate into inside connecting tube 1 and rolling bearing, and the pressure value is smaller to be avoided
Liquid medium enters the service life of bearing block 6 internal influence rolling bearing, and described filler sealing 53 can be sealed in the pump housing 2
The liquid medium in portion, even if there is a small amount of leakage, it is also possible to flow back into liquid pool by dismantling window 51, nor affect on the axis of rolling
The service life held, finally ensure that the normal operation of submerged pump.The utility model devises dismounting window 51, facilitates sealing
The installation and maintenance of component, and simple structure, must even not consider that the internal pressure of the pump housing 2 causes liquid to penetrate into the axis of rolling to it
