Abstract
A kind of rod collar and rod connector push away bearing surface corrosion-preventing device, including rod connector, rod collar and corrosion-preventing device.It is provided with bearing surface that the center that a upper and lower is provided with symmetrical grooves sets round-meshed cylinder corrosion-preventing device or top sets reeded center and sets round-meshed cylinder corrosion-preventing device or gasket type cylinder corrosion-preventing device in pushing away of rod collar and rod connector, what corrosion-preventing device passed through pumping rod collar rotating compression sealing rod collar and rod connector pushes away bearing surface.With pushing away of rod connector, corrosion-preventing device is added on bearing surface in rod collar, enhance the sealing intensity between rod collar and rod connector, prevent rod connector pushes away bearing surface and rod collar end face by corrosion in water, will not produce dropout and the disconnected de- phenomenon of corrosion.Corrosion-preventing device is molded into the rountrip that sucker rod is facilitated on rod connector, installs or removes corrosion-preventing device without each actuating oil-pumping unit, improve oil well operation speed.
Description
Technical field
This utility model is related to oilfield machinery manufacturing technology field, and specifically a kind of rod collar is pushed away with rod connector
Bearing surface corrosion-preventing device.
Background technology
At present, oil well mainly has bar mechanical oil well, and sucker rod is all pumping rod made by steel.Because oil field is in
Tertiary phase, well water great majority, all in percentage more than 80, contain substantial amounts of sulfur, acid, calcium, magnesium plasma in water,
More serious to sucker rod corrosion and scaling ratio, cause sucker rod that disconnected de- phenomenon often occurs, workover treatment probability significantly increases, seriously
The normal production of impact oil well.Research and produce a kind of Anti-corrosion sucker rod of special material spray treatment for this our company, substantially
Solve the problems, such as above-mentioned prior art.After using through a period of time, discovery rod collar is pushed away with rod collar
Bearing surface is poorly sealed, and the sewage with corrosion permeates in the same old way, rod connector is pushed away with bearing surface and the end face of rod collar is made
Become corrosion although rod collar coats Co-based alloy powder or tungsten-carbide powder coating with the perimeter surface of rod collar,
But do not prevent end face corrosion, cause the corrosion of table internal layer to empty phenomenon, cause rod parting, just having a strong impact on pumpingh well
Often produce.
Content of the invention
The purpose of this utility model is to provide a rod collar and rod connector to push away bearing surface corrosion-preventing device, overcome above-mentioned
Defect with the presence of technology.
The technical solution of the utility model is achieved in the following ways：
This utility model include rod connector, rod collar and corrosion-preventing device it is characterised in that：Rod collar with
The bearing surface that pushes away of rod connector is provided with the center that a upper and lower is provided with symmetrical grooves to set round-meshed cylinder anti-corrosion
Device or top set reeded center and set round-meshed cylinder corrosion-preventing device or gasket type cylinder corrosion-preventing device, and corrosion-preventing device passes through to take out
What beam hanger box cupling rotatably compressed sealing rod collar and rod connector pushes away bearing surface.
Described corrosion-preventing device adopts polytetrafluoroethylmaterial material or the high temperature high voltage resistant of aluminium or stainless steel or high temperature high voltage resistant
Nylon material make, will prevent when being made using the nylon material of the polytetrafluoroethylmaterial material of high temperature high voltage resistant or high temperature high voltage resistant
Rotten device is molded in rod connector.
This utility model has advantages below：
1st, add corrosion-preventing device in rod collar and pushing away of rod connector in bearing surface, enhance rod collar and oil pumping
Sealing intensity between knock-off joint it is therefore prevented that rod connector push away bearing surface and rod collar end face by corrosion in water, will not
Produce corrosion to thread off and the disconnected de- phenomenon of corrosion.
2nd, corrosion-preventing device is molded into the rountrip facilitating sucker rod in rod connector, without each actuating oil-pumping unit peace
Dress or dismounting corrosion-preventing device, improve oil well operation speed.
3rd, in rod collar and pushing away of rod connector, corrosion-preventing device is added on bearing surface, make the anti-of special material spray treatment
Rotten sucker rod is really achieved the purpose of the service life improving sucker rod roofbolt.
Brief description
Fig. 1-structural representation of the present utility model
The structural representation of Fig. 2-corrosion-preventing device
The rod connector of in figure 1-, 2- rod collar, 3- corrosion-preventing device.
Specific embodiment
For disclosing the technical solution of the utility model further, made specifically by embodiment with reference to Figure of description
Bright：
This utility model include rod connector 1, rod collar 2 and corrosion-preventing device 3 it is characterised in that：Connect in sucker rod
The bearing surface that pushes away of hoop and rod connector is provided with the center that a upper and lower is provided with symmetrical grooves and sets round-meshed cylinder
Corrosion-preventing device or top set reeded center and set round-meshed cylinder corrosion-preventing device or gasket type cylinder corrosion-preventing device, and corrosion-preventing device leads to
That crosses pumping rod collar rotating compression sealing rod collar and rod connector pushes away bearing surface.
In use, corrosion-preventing device preferably adopts the polytetrafluoroethylmaterial material of resistance to interior High Temperature High Pressure or the Buddhist nun of high temperature high voltage resistant
Imperial material makes, and because it can be easily molded in rod connector, without single installation or removal, can facilitate sucker rod
Remove, and just can reach preferable sealing effectiveness without applying too big pressure.This utility model be mainly applicable to sucker rod,
Antiseptic sucker rod roofbolt is made on rod connector and rod collar week top layer, does not take antiseptic sucker rod bar
Post need not be used, and because its each corrosion location is synchronous, adds that corrosion-preventing device also will not improve the service life of sucker rod roofbolt.
