Abstract
The utility model discloses a kind of screw pump/screw drilling tool motor improving greasy property, including stator case, be fixed with rubber bushing in described stator case, the inner chamber of described rubber bushing is provided with screw rotor；The inner surface of described rubber bushing is interval with the pit for retaining lubricating fluid；Or the outer surface of described screw rotor is interval with the pit for retaining lubricating fluid；Because the outer surface that the inner surface of described rubber bushing is provided with pit or described screw rotor is provided with pit, certain oil or liquid can be stored in pit, so all without dry grinding and spontaneous imbibition phenomena occur again between stator rubber inner surface and rotor outer surface when no matter being to run into vacuum gas or feed flow deficiency；Pit stores certain liquid always, starts regardless of the time the lightest, thus add certain safety；Pit reduces relative to two contact surface area, and the power of use is the most relatively reduced, has saved certain energy.
Description
Technical field
This utility model relates to a kind of screw pump or screw drilling tool motor, particularly relate to the screw pump of a kind of reliable operation/
Screw drilling tool motor.
Background technology
As it is shown in figure 5, the screw pump of prior art or screw drilling tool motor include stator case, solid in described stator case
Surely being provided with rubber bushing, the inner chamber of described rubber bushing is provided with screw rotor, described rubber bushing and described screw rotor and connects
Contacting surface is all smooth, and contact surface is bigger.Shortcoming is: the most particularly screw pump is when running into evacuation or gas-bearing formation, rubber bushing
Producing dry grinding with screw rotor surface, there is vacuum self-priming thus can not do relative motion again in two surfaces, namely in industry
" gas lock " phenomenon.(2) rubber bushing and screw rotor contact surface area are big (the particularly motor of length standing time), screw drill
The startup pressure of tool is big, occurs that to compression pump and pipeline pressure raises suddenly and easily produces danger.(3) rubber bushing and screw rod turn
The power of the big consumption of sub-contact area is the biggest.
Utility model content
Technical problem to be solved in the utility model be to provide the screw pump of the raising greasy property of a kind of reliable operation/
Screw drilling tool motor.
For solving above-mentioned technical problem, the technical solution of the utility model is: improve the screw pump/screw drill of greasy property
Tool motor, including stator case, is fixed with rubber bushing in described stator case, the inner chamber of described rubber bushing is provided with spiral shell
Bar rotor, the inner surface of described rubber bushing is interval with the pit for retaining lubricating fluid.
Smooth interior surfaces transition as preferred technical scheme, described pit edge and described rubber bushing.
As preferred technical scheme, the degree of depth of described pit is not more than 0.2mm.
For solving above-mentioned technical problem, the screw pump/spiral shell that another solution is that raising greasy property of the present utility model
Bar driller motor, including stator case, is fixed with rubber bushing in described stator case, the inner chamber of described rubber bushing is installed
Screw rotor, the outer surface of described screw rotor is had to be interval with the pit for retaining lubricating fluid.
Outer surface smoother transition as preferred technical scheme, described pit edge and described screw rotor.
As preferred technical scheme, the degree of depth of described pit is not more than 0.2mm.
Owing to have employed technique scheme, improve the screw pump/screw drilling tool motor of greasy property, including stator case
Body, is fixed with rubber bushing in described stator case, the inner chamber of described rubber bushing is provided with screw rotor；Described rubber serves as a contrast
The inner surface of set is interval with the smooth interior surfaces of the pit for retaining lubricating fluid, described pit edge and described rubber bushing
Transition；Or the outer surface of described screw rotor is interval with the pit for retaining lubricating fluid, and described pit edge is with described
The outer surface smoother transition of screw rotor；Because the inner surface of described rubber bushing is provided with outside pit or described screw rotor
Surface is provided with pit, can store certain oil or liquid in pit, during so no matter being to run into vacuum gas or feed flow deficiency
All without dry grinding and spontaneous imbibition phenomena occur again between stator rubber inner surface and rotor outer surface；Pit store always certain
Liquid, start regardless of the time the lightest, thus add certain safety；Pit is relative to two surface contact surfaces
Long-pending reduction, the power of use is the most relatively reduced, has saved certain energy.

Detailed description of the invention
Below in conjunction with the accompanying drawings and embodiment, this utility model is expanded on further.In the following detailed description, only by saying
Bright mode describes some one exemplary embodiment of the present utility model.Undoubtedly, those of ordinary skill in the art is permissible
Recognize, in the case of without departing from spirit and scope of the present utility model, can be by various different modes to described
Embodiment is modified.Therefore, accompanying drawing and description are inherently protection that is the most illustrative rather than that be used for limiting claim
Scope.
Embodiment one: as depicted in figs. 1 and 2, improves the screw pump/screw drilling tool motor of greasy property, including stator case
Body 1, is fixed with rubber bushing 2 in described stator case 1, the inner chamber of described rubber bushing 2 is provided with screw rotor 3, described
The inner surface of rubber bushing 2 is interval with the pit 4 for retaining lubricating fluid, described pit 4 edge and described rubber bushing 2
Smooth interior surfaces transition；In the present embodiment, the degree of depth of described pit 4 is not more than 0.2mm.
Because the inner surface of described rubber bushing 2 is provided with pit 4, in pit 4, certain oil or liquid can be stored, so
All without dry grinding occurs again between stator rubber inner surface and rotor outer surface when being no matter to run into vacuum gas or feed flow deficiency
And spontaneous imbibition phenomena；Pit 4 stores certain liquid always, starts regardless of the time the lightest, thus add
Certain safety；Relative two contact surface area of pit 4 reduce, and the power of use is the most relatively reduced, has saved certain energy
Source.
Embodiment two: as shown in Figure 3 and Figure 4, improves the screw pump/screw drilling tool motor of greasy property, including stator case
Body 1, is fixed with rubber bushing 2 in described stator case 1, the inner chamber of described rubber bushing 2 is provided with screw rotor 3, described
The outer surface of screw rotor 3 is interval with the pit 4 for retaining lubricating fluid, described pit 4 edge and described screw rotor 3
Outer surface smoother transition；In the present embodiment, the degree of depth of described pit 4 is not more than 0.2mm.
Because the outer surface of described screw rotor 3 is provided with pit 4, in pit 4, certain oil or liquid can be stored, so
All without dry grinding occurs again between stator rubber inner surface and rotor outer surface when being no matter to run into vacuum gas or feed flow deficiency
And spontaneous imbibition phenomena；Pit 4 stores certain liquid always, starts regardless of the time the lightest, thus add
Certain safety；Relative two contact surface area of pit 4 reduce, and the power of use is the most relatively reduced, has saved certain energy
