Abstract
Oil-extractor polish-rod damper is a kind of indispensable accessory of oilfield pumping well combination polished rod eye carrying underground load.In actual production, often there is the phenomenon that unloading crams load, therefore can the accident such as the side's of generation clamp strip, polished rod break, oil well pump damage failure.Pumping unit time efficiency has been had a strong impact on, have impact on yield, has increased cost input.The purpose of this utility model is to provide a kind of oil-extractor polish-rod damper that a kind of simple in construction, easy for installation, safety coefficient improves, and it overcomes the shortcomings that current technology is present.It by oil-extractor polish-rod absorber main body, carrying set, butterfly spring, butter hole, etc. form.Carrying is placed in absorber main body, can be moved up and down；In absorber main body, following positioned at carrying set, butterfly spring compresses butterfly spring when eating load, restores to the original state during unloading, plays cushioning effect.
Description
Technical field
It the utility model is related to a kind of oilfield pumping well auxiliary accessories, especially oil-extractor polish-rod damper.
Background technology
Oil-extractor polish-rod damper is a kind of indispensable of oilfield pumping well combination polished rod eye carrying underground load
Accessory.In actual production, test indicator card, dead space, unloading adjustment maintenance oil pumper and wax deposition salt crust sand card etc. are adjusted,
Often there is unloading and cram the phenomenon of load, thus can the side's of generation clamp strip, polished rod break, hair plait plays torsion, and hair plait breaks, even
Underground sucker rod is disconnected de-, the accident such as oil well pump damage failure.Pumping unit time efficiency has been had a strong impact on, have impact on yield, has increased cost
Input.
The content of the invention
The purpose of this utility model is to provide a kind of oil pumper that a kind of simple in construction, easy for installation, safety coefficient improves
Polished rod shock absorber, it overcomes the shortcomings that current technology is present.
It is of the present utility model be achieved in that it be by oil-extractor polish-rod absorber main body, carrying set, butterfly spring,
Bottom footwear, butter hole, grease nipple, the composition such as hole is unloaded on the footwear of bottom.Carrying is placed in absorber main body, can be moved up and down；Butterfly bullet
In absorber main body, following positioned at carrying set, butterfly spring compresses spring when eating load, restores to the original state during unloading, plays damping work
With；Bottom footwear are located at absorber main body foot, with damper screwed connection, are embedded in body, play back cover effect；Butter hole exists
In the middle part of absorber main body, with grease nipple screwed connection, play a part of lubricating maintenance damper for filling butter.
Meaning of the present utility model：First, having butterfly spring in oil-extractor polish-rod damper, cushioning buffer effect is played；Two
It is that oil-extractor polish-rod damper is provided with butter hole, butter can be filled, play lubrication；Third, carrying set can protect oil pumping
Machine polished rod is injury-free；Fourth, installation and safeguarding convenient disassembly；Fifth, service life is grown, operating efficiency is high；Sixth, ensure that makes
With safety, safety coefficient is improved.
