Abstract
It the utility model is related to a kind of two-way sand control installation of guide bearing of well immersible pump, it is characterised in that：It is made up of connection frame, spacer, key, sand-throwing ring, axle sleeve, guide bearing and pump shaft, two spacers, sand-throwing ring are symmetrical arranged the upper and lower of axle sleeve, sand-throwing ring, axle sleeve are fixedly connected by key with pump shaft, guide bearing is provided with connection frame, guide bearing 6 enters 1 inner hole of connection frame by pressure assembling force and ensures that guide bearing 6 does not rotate with connection frame 1, when pump shaft rotates, sleeve outer circle relatively rotates with guide bearing endoporus.The two-way sand control installation of guide bearing of the utility model well immersible pump, there is reasonable in design, simple in construction, assembly technology to require low, it is highly reliable, precision is easily controlled, the characteristics of cost is low, fault rate can be reduced, extend the service life of pump, axle sleeve abrasion is easily changed, and reduces maintenance cost.
Description
Technical field
The utility model is applied to the sand control installation of multilevel well diving, more particularly to a kind of guide bearing of well immersible pump
Two-way sand control installation.
Background technology
At present, domestic well in the prior art uses two kinds of materials with immersible pump guide bearing：One kind is quality of rubber materials, due to
There is the shortcomings of not wear-resisting, easy to aging in the reason for its material, the rate of wear is fast, service life is low.It is not particularly suitable in silt ring
Run under border.Another material is copper alloy, and current flow through in pump shaft and copper sheathing gap, it is easy to causes guide bearing to wear, ties up
It is high to repair expense.The common drawback of both materials is：Immersible pump is when conveying liquid containing silt, because guide bearing both ends do not have
Anti- device for silt, guide bearing and pump shaft Fast Wearing are caused, cause the problems such as life of product is low, and maintenance cost is high.
The content of the invention
The utility model overcomes above-mentioned defect, it is therefore an objective to is not ground to solve well with immersible pump guide bearing by silt particle
Damage, and the cooling of bearing is not influenceed, reduce maintenance cost, improve service life, there is provided a kind of guide bearing of well immersible pump is double
To sand control installation.
The two-way sand control installation of guide bearing of the utility model well immersible pump, it is characterised in that：Be by connection frame, spacer, key,
Sand-throwing ring, axle sleeve, guide bearing and pump shaft composition, two spacers, sand-throwing ring are symmetrical arranged the upper and lower of axle sleeve, sand-throwing ring, axle sleeve
It is fixedly connected by key with pump shaft, guide bearing is provided with connection frame, guide bearing is fixedly connected by interference power with connection frame, and pump shaft rotates
When, sleeve outer circle relatively rotates with guide bearing endoporus.
The two-way sand control installation of guide bearing of the utility model well immersible pump, there is reasonable in design, simple in construction, assembler
The characteristics of skill requires low, highly reliable, is easily controlled precision, and cost is low, can reduce fault rate, extend the service life of pump, axle
Set abrasion is easily changed, and reduces maintenance cost.
Brief description of the drawings
Fig. 1 is the two-way sand control installation structural representation of guide bearing of well immersible pump；
In figure：1 it is connection frame, 2 be spacer, 3 be key, 4 be sand-throwing ring, 5 be axle sleeve, 6 be guide bearing, 7 is pump shaft.
Embodiment
The utility model well is achieved in that to do have below in conjunction with the accompanying drawings with the two-way sand control installation of the guide bearing of immersible pump
Body explanation.
See Fig. 1, the two-way sand control installation of guide bearing of well immersible pump, be by connection frame 1, spacer 2, key 3, sand-throwing ring 4, axle sleeve
5th, guide bearing 6 and pump shaft 7 form, and two spacers 2, sand-throwing ring 4 are symmetrical arranged the upper and lower of axle sleeve 5, and sand-throwing ring 4, axle sleeve 5 are logical
Cross key 3 to be fixedly connected with pump shaft 7, guide bearing 6 is provided with connection frame 1, guide bearing 6 is fixedly connected by interference power with connection frame 1, pump shaft
During 7 rotation, axle sleeve 5 is cylindrical to be relatively rotated with the endoporus of guide bearing 6, and certralizing ability is played to pump shaft 7.
Join during pump work frame 1 be fixed to it is static do not rotate, guide bearing 6 enters connection frame 1 inner hole by pressure assembling force and ensures to lead
Bearing 6 does not rotate with connection frame 1,
Pump shaft 7 is rotates during pump work, and axle sleeve 5 is fixedly connected by key 3 with pump shaft 7, and two spacers 2, sand-throwing ring 4 are symmetrical
The upper and lower of axle sleeve 5 is set, and spacer 2, axle sleeve 5, the end face of sand-throwing ring 4 contact with each other guarantee axially without play
Axle sleeve 5 is cylindrical small with the endoporus sliding friction of guide bearing 6,4 inner hole of sand-throwing ring and the cylindrical formation of guide bearing 6 during pump work
Gap prevents silt particle from entering.Two sand-throwing rings 4 are rotated with pump shaft 7, and the endoporus of sand-throwing ring 4 is relative with the excircle of guide bearing 6 to be turned
It is dynamic, dynamic sealing space is formed to guide bearing 6, due to gap very little, the silt in liquid is not easily accessed guide bearing 6 and axle
In the gap of set 5, effectively prevent silt in liquid from entering, complete the both ends sediment prevention function of guide bearing 6.Axle sleeve 5 is mounted on pump shaft,
Friction is rotated against with guide bearing 6, reduces the rate of wear of guide bearing 6, reduces fault rate, extends the service life of pump,
The abrasion of axle sleeve 5 is easily changed, and reduces maintenance cost.
The two-way sand control installation of guide bearing of the utility model well immersible pump, there is reasonable in design, simple in construction, assembler
The characteristics of skill requires low, highly reliable, is easily controlled precision, and cost is low.
