Abstract
The utility model provides a kind of underground and locks adjusting apparatus with pump shaft head, which solves following technical problem：The form locked back-to-back using round nut with the locking adjustment of pump shaft head under existing well, because the operation of pump is always with vibration, after running a period of time, round nut can loosen, cause whole rotor shifting, and then influence the overall performance of pump, influence the reliability of pump operating, the utility model is provided with axle, axle is provided with Sliding bush, Sliding bush side is provided with thrust adjusting pad, thrust adjusting pad opposite side is provided with locking nut, axle is provided with mounting hole, axial gap is provided between thrust adjusting pad and locking nut, locking nut is provided with Top fastening screw, thrust adjusting pad is the pad of three different-thickness.The utility model can be widely applied to the spindle nose locking adjusting apparatus of pump.
Description
Technical field
A kind of spindle nose locking device is the utility model is related to, adjustment dress is locked with pump shaft head more particularly to a kind of underground
Put.
Background technology
As underground uses the development of industry, higher requirement is proposed with pump to underground, because underground work is special
Property is, it is necessary to which underground pump has higher stability.
The form that traditional underground is locked back-to-back with the locking adjustment of pump shaft head using round nut, because the operation of pump is one
Straight with vibration, after running a period of time, round nut can loosen, and cause whole rotor shifting, and then influence the globality of pump
Can, influence the reliability that pump operates.
The content of the invention
Technical problem to be solved in the utility model is as follows：For using pump shaft head locking adjustment under existing well using circle spiral shell
The form that mother locks back-to-back, because the operation of pump is always with vibration, after running a period of time, round nut can loosen,
Cause whole rotor shifting, and then influence the overall performance of pump, influence the reliability of pump operating.The utility model provides one
Adjusting apparatus is locked in kind underground with pump shaft head, and it does not have to the form that round nut is locked back-to-back, avoids because the vibration of pump causes
Round nut loosens, and then causes whole rotor shifting, influences the overall performance of pump, improves the reliability of pump operating.
Therefore, the technical solution of the utility model is, adjusting apparatus is locked in a kind of underground with pump shaft head, provided with axle, on axle
Provided with Sliding bush, Sliding bush side is provided with thrust adjusting pad, and thrust adjusting pad opposite side is provided with locking nut, and axle is provided with
Mounting hole, is provided with axial gap between thrust adjusting pad and locking nut, locking nut is provided with Top fastening screw.
Preferably, thrust adjusting pad is the pad of three different-thickness.
Preferably, locking nut is cylindrical is provided with two parallel planes.
The utility model beneficial effect is that, because provided with axle, axle is provided with Sliding bush, Sliding bush side is provided with thrust
Adjusting pad, thrust adjusting pad opposite side are provided with locking nut, and axle is provided with mounting hole, is provided between thrust adjusting pad and locking nut
Axial gap, locking nut are provided with Top fastening screw, when underground is locked with pump shaft head, the shape locked back-to-back without round nut
Formula, avoid because the vibration of pump causes round nut to loosen, and then causes whole rotor shifting, influence the overall performance of pump, carry
The high reliability of pump operating.

Embodiment
The utility model is described further with reference to embodiment.
Adjusting apparatus is locked in a kind of underground with pump shaft head, and provided with axle 4, axle 4 is provided with Sliding bush 1, the side of Sliding bush 1
Provided with thrust adjusting pad 6, thrust adjusting pad 6 is the pad of three different-thickness, and for adjusting axial gap, thrust adjusting pad 6 is another
Side is provided with locking nut 7, and locking nut 7 is provided with Top fastening screw 3, for preventing the rotation of locking nut 7 from loosening, is set on axle 4
There is mounting hole 5, coordinate with locking nut 7 and install, axial gap 2 is provided between thrust adjusting pad 6 and locking nut 7, for ensureing
Axial float in operation process will not cause axle 4 to deform, and locking nut 7 is cylindrical to be provided with two parallel planes, is easy to twist
Clamping tool clamps.
Only as described above, only specific embodiment of the utility model, when the utility model can not be limited with this
The scope of implementation, therefore the displacement of its equivalent assemblies, or the equivalent variations made according to the utility model patent protection domain and modification,
It all should still belong to the category that the utility model claims book is covered.
