Description
Technical field
The utility model relates to petroleum machinery, is specifically related to the seal member of oil pumping machine well head.
Background technology
Oil pumper after long-term use, due to the change of surface layer, the position of wellhead component often produces skew, this changes with regard to making the relative position of derrick and well head, the sucker rod of oil pumper will produce eccentric wear with wellhead component, sucker rod premature failure can be made on the one hand, well head also can be made on the other hand because of the problem of heel and toe wear generation leakage of oil.The heel and toe wear of oil pumping machine well head and occur that Leakage all can bring no small economic loss to enterprise and produce environment pollution.The after date when sucker rod of oil pumper normally uses one section, also can scrap because of wearing and tearing, the sucker rod after scrapping, if reasonably repaired utilization, will save not skinny device investment.
In order to solve the problem of well head eccentric wear, Authorization Notice No. is CN202767934U, name is called that the utility model patent of clamp connection type blowout preventer provides a kind of automatically deviation-adjusting device adopting eccentric ball head, by this displacement of device bulb part in the rotation and level of the centre of sphere, the problem of well head eccentric wear can be corrected to a certain extent when assembling and using.But when reality uses, because in its horizontal direction, eccentric arm is fixing, the track of its tuningout has limitation, this brings difficulty with regard to giving the adjustment of staff in practical operation, makes rectifying effect not ideal enough.
Summary of the invention
Technical problem to be solved in the utility model is: provide a kind of oil pumper wear-and corrosion-resistant rod member bias-adjusting sealing combination unit, make tuningout structure more reasonable, can solve well head eccentric wear problem better.
Technical solution of the present utility model is: it comprises sucker rod, hoop, spherojoint, bulb pressure cap and transition joint, it is characterized in that: described hoop is provided with bulb chamber in epimere, the bulb base and bulb pressure ring that are annular is provided with in bulb chamber, bulb base and bulb pressure ring inwall are equipped with the Internal Spherical Surface matched with the spherical surface body of described spherojoint lower end, the Internal Spherical Surface of bulb base is connected with the spherical surface body lower seal of spherojoint, the bottom of bulb base is connected with the bulb chamber sealing bottom surface of hoop and can slides along its horizontal direction, bulb pressure ring is enclosed within the top of the spherical surface body of spherojoint, the inner top surface that the end face of bulb pressure ring is against described bulb pressure cap can slide along its horizontal direction.
Technique effect of the present utility model is: it has reasonable in design, operation and maintenance advantage easily, can solve well head eccentric wear problem better.After aboveground assembling, before pressure cap locking, bulb part can be shifted by automatic horizontal under the extruding of sucker rod, and displacement can adapt to automatically.Meanwhile, waste and old sucker rod can be re-used by complex abrasion-proof anticorrosive coat.

Fig. 2 is the sectional structure schematic diagram of the utility model sucker rod.
Detailed description of the invention
As illustrated in fig. 1 and 2, it comprises sucker rod 1, hoop 2, spherojoint 3, bulb pressure cap 4, lower seal assembly 5, transition joint 6, upper black box 7 and upper pressing cap 8, described hoop 2 is provided with bulb chamber 9 in epimere, the bulb base 10 and bulb pressure ring 11 that are annular is provided with in bulb chamber 9, bulb base 10 and bulb pressure ring 11 inwall are equipped with the Internal Spherical Surface matched with the spherical surface body 12 of described spherojoint 3 lower end, the Internal Spherical Surface of bulb base 10 is connected with spherical surface body 12 lower seal of spherojoint 3, the bottom of bulb base 10 is connected with bulb chamber 9 sealing bottom surface of hoop 2 and can slides along its horizontal direction, bulb pressure ring 11 is enclosed within the top of the spherical surface body 12 of spherojoint 3, the inner top surface that the end face of bulb pressure ring 11 is against described bulb pressure cap 4 can slide along its horizontal direction.
The bossed ball chamber 13 be equipped with spray-proof ball 14 received is established in described transition joint 6 in stage casing.
The described bottom surface receiving ball chamber 13 is to recessed taper surface.
Described sucker rod 1 external surface is provided with wear-and corrosion-resistant layer 15.
Described hoop 2 bottom is provided with connecting thread.
Wear-and corrosion-resistant rod member by the process combining such as cold-drawn, polishing 304 stainless steel sleeve pipe, reaches the object of wear-and corrosion-resistant, adhesion >=30MPa, compound rear bar body diameter Φ 32mm after the body of rod and stainless steel sleeve pipe compound.Blowout prevention function that the utility model has well head offset function, bar breaks, efficient sealed function, replacement wax removal valve function and the defencive function to polished rod; can reach and extend polished rod application life; strengthen the object of polished rod antiseptic property; the use of compound rod member simultaneously also improves anti-wear performance; reduce staff labor intensity; energy-saving and cost-reducing, put forward the running efficiency of high oil well.Old pumping rod reparation utilizes and has saved a large amount of funds.
Operating principle:
1, spherojoint can play " universal joint " effect, when well head and horse head have skew (misaligning), can first by spherojoint, ball base and ball pressure cap in adjustment long hoop head, its integral level be offset, make polished rod centering well head, reduce the abrasion that sucker rod misaligns generation;
2, when rod broken, inner chamber spray-proof ball can under the effect of wellbore pressure shutoff oil discharge passage, prevent blowout;
3, rotation transition joint is exerted pressure to expansion packing element and is made it expand, and can replace wax removal valve, reach sealing function.
This product can bind round seat with 120mm, 135mm length by the plinth that replacing is different and be connected, and also can be connected with inner and outer pipe hickey, make user have better selection.
By repeatedly field experiment, this product substantially increases anticorrosion, wear-resisting effect, reduces frictional force; On the apparatus, in, under, devise nylon guide pin bushing and lining, ensure sucker rod mediate all the time in running, ensure do not produce eccentric wear, so substantially prolongs the application life of sucker rod, reduce material consumption.Bar blowout prevention function of breaking can reduce environment pollution, is environment-friendly products, alleviates workman and clears up the labour intensity that greasy dirt pays.
In test use procedure, there is not run, drip, leak phenomenon in this device, respond well, and after installing this device, change a packing by original every couple of days and extend to replacing in two, a three months packing, result of use is better than existing apparatus greatly.
