Description
One, technical field
The present invention relates to a kind of submersible pump accessory, particularly relate to a kind of axial force balancing device for electric diving pump.
Two, background technology
At present, in order to solve the problem of northern China deep phreatic water drainage underground, water-filling submersible electric pump is typically used.
At present, the water-filling submersible electric pump of the existing production of China is the most all to use axial thrust balancing devices to bear the axial of electric pump
Power, but the most all there is leakage rate greatly in axial thrust balancing devices the most on the market, dustproof effect is poor, and structure is complicated, uses
The shortcomings such as the life-span is short.Sealing is strong the most on the market, it is possible to is prevented effectively from leakage, has outstanding dustproof effect, structure simultaneously
Simply, service life more lengthens, thus reduces loss, and the axial thrust balancing devices reducing production cost is not the most found, and has
To be developed.
Three, summary of the invention
In order to overcome the weak point of existing submersible pump accessory, the invention provides a kind of submersible pump axial force balance
Device.
The technical scheme is that and be achieved in that.
A kind of axial force balancing device for electric diving pump of this programme, including pressure release shell and pump shaft, sets inside described pressure release shell
Being equipped with stationary ring, described stationary ring is internally provided with cavity, is provided with rotating ring bottom described stationary ring, and described pump shaft is fixed with rotating ring center
Connect and stretch into inside stationary ring；The cavity inner wall of described stationary ring is provided with pressure release columella around pump shaft top and holds, described pressure release shell
Being provided with steel bushing between bearing and pump shaft, described stationary ring top is provided with the exhaust duct extended to outside pressure release shell, this exhaust duct
End is provided with screw；It is provided with sealing strip ringwise on described stationary ring and rotating ring contact surface, this sealing strip is provided with groove,
Seal in alloy bar it is provided with on position corresponding with groove on described rotating ring；It is positioned at pump shaft and the stationary ring top of described stationary ring cavity
Spring it is provided with between face.
Cavity after described stationary ring and rotating ring combination and between pressure release shell is higher-pressure region, is low-pressure area in described exhaust duct.
The invention have benefit that: this product-forming is attractive in appearance, cost-effective, and sealing is strong, it is possible to is prevented effectively from and lets out
Dew, has outstanding dustproof effect, simple in construction simultaneously, more lengthens service life, thus reduce loss, reduces production cost.
Four, accompanying drawing explanation
Fig. 1 is the structural representation of the present invention.
Five, detailed description of the invention
Below in conjunction with the accompanying drawings the detailed description of the invention of the present invention is made brief description.
A kind of axial force balancing device for electric diving pump as depicted, including pressure release shell 1 and pump shaft 4, in described pressure release shell 1
Portion is provided with stationary ring 2, and described stationary ring 2 is internally provided with cavity, is provided with rotating ring 3 bottom described stationary ring 2, and described pump shaft 4 is with dynamic
Ring 3 center is fixing to be connected and stretches into stationary ring 2 inside；The cavity inner wall of described stationary ring 2 is provided with pressure release columella around pump shaft 4 top
Holding 5, described pressure release columella holds and is provided with steel bushing 6 between 5 and pump shaft 4, and described stationary ring 2 top is provided with and extends to outside pressure release shell 1
The exhaust duct 7 in portion, this exhaust duct 7 end is provided with screw 8；Described stationary ring 2 is provided with sealing on rotating ring 3 contact surface ringwise
Bar 9, this sealing strip 9 is provided with groove 10, position corresponding with groove 10 on described rotating ring 3 is provided with seal in alloy bar
10；It is provided with spring 11 between pump shaft 4 and stationary ring 2 end face in described stationary ring 2 cavity.
Cavity after described stationary ring 2 and rotating ring 3 combination and between pressure release shell 1 is higher-pressure region, is low pressure in described exhaust duct 7
District.
The work process of this example: using the present invention when, pump shaft 4 is rotating when, and pump shaft 4 drives rotating ring 3
Rotating together, described stationary ring 2 is provided with sealing strip 9 on rotating ring 3 contact surface ringwise, and this sealing strip 9 is provided with groove 10,
Be provided with seal in alloy bar 10 on position corresponding with groove 10 on described rotating ring 3, seal in alloy bar 10 to arrange comparison traditional
Rubber seal etc., there is wearability higher, the most perishable, service life is longer a little, simultaneously rotating ring 3 rotate time
Waiting, can be thrown away by the gravel that enter between rotating ring 3 and stationary ring 2, effective sand prevention, when pump shaft 4 rotates when, liquid enters pressure release
A higher-pressure region can be formed after cavity between shell 1 inwall and stationary ring 2 and rotating ring 3, and exhaust duct 7 the most just becomes low
Nip, therefore pump shaft 4 can move to exhaust duct 7 direction, can be played the effect of opposite direction effect by the effect of spring 11 simultaneously
Really, this process can realize the axial force balance effect of pump shaft 4, and cost-effective, sealing is strong, it is possible to be prevented effectively from leakage, with
Time there is outstanding dustproof effect, simple in construction, more lengthen service life, thus reduce loss, reduce production cost.
Above one embodiment of the present of invention is described in detail, but described content has been only the preferable enforcement of the present invention
Example, it is impossible to be considered the practical range for limiting the present invention.All impartial changes made according to the present patent application scope and improvement
Deng, within all should still belonging to the patent covering scope of the present invention.
