Description
Technical field:
This utility model belongs to technical field of oil field equipment, is specifically related to a kind of universal deviation correcting device of oil pumping machine well head.
Background technology:
At present, when adjustment sucker rod bias misaligns at the scene, it is that walking beam on pumping units part and well head base are adjusted, owing to this operating type workload is big, task difficulty is big, inconvenience construction, waste time and energy, so up to more than 90% sucker rod does not carry out tuningout, only the biggest eccentric being just adjusted, and this tuningout mode can not fundamentally solve the problem that sucker rod bias misaligns, sucker rod is made to be in condition of misalignment in well head operates, oil pumping machine well head is caused to leak, make sucker rod serious wear, significantly reduce service life and the sealing effectiveness of sealed packing box of sucker rod, reduce work efficiency, but also cause environmental pollution, not only cause waste resource but also pollute environment, greatly have impact on production and the management in oil field, have impact on economic benefit and the social benefit of enterprise.So, it is the most necessary for designing a kind of universal deviation correcting device of oil pumping machine well head easy and simple to handle.
Utility model content:
In place of this utility model makes up and improves above-mentioned the deficiencies in the prior art, provide a kind of simple in construction, reasonable in design, easy and simple to handle, energy-conserving and environment-protective, length in service life, tuningout is effective, with low cost, can improve the universal deviation correcting device of a kind of oil pumping machine well head of leakage efficiency, it is easy to promotion and application on a large scale.
The technical solution adopted in the utility model is: a kind of universal deviation correcting device of oil pumping machine well head, including sucker rod body, connect seal box and universal ball end base, eccentric tuningout universal ball end is installed in universal ball end base, it is provided with anti-synchronization steel ball in the steel bead groove of eccentric tuningout universal ball end, it is provided with sealing ring in the o-ring groove of eccentric tuningout universal ball end, it is provided with blowout prevention glueballs in eccentric tuningout universal ball end, it is provided with universal ball end upper cover outside eccentric tuningout universal ball end, universal ball end upper cover is connected with universal ball end whorl of base, universal ball end base bottom is dual-purpose well head attachment structure.
The beneficial effects of the utility model: simple in construction, reasonable in design, easy and simple to handle, energy-conserving and environment-protective, service life is long, and tuningout is effective, with low cost, it is possible to increase leakage efficiency, it is easy to promotion and application on a large scale.Owing to bias is to use three grades of trigonometric expression figures to connect to dish, can arbitrarily adjust change angle according to field condition, it is adaptable to sucker rod is eccentric without departing from the automatic deflection adjusting at any angle in the range of well head.Using eccentric tuningout universal ball end and universal ball end base to connect, it reaches the adjustment of longitudinal angle excursion, makes oil pumping machine well head adapt to the angle that well head is tilted by pumping unit horsehead.Universal deviation correcting device, from longitudinally, laterally without departing from adjusting in the range of well head and eccentric, fundamentally solves this difficult problem, enables sucker rod well to run when centering, thus improve the service life of sucker rod；Oil pumping machine well head bias and caput Equi Asini and well head deflection is additionally made to have obtained effective control, ensure that sucker rod is in operation and remain that centering runs, sealed object in well head sealing packing box also can the most reasonably hold sucker rod tightly, reach the sealing effectiveness that wellhead packing box is good, and improve leakage efficiency.
Accompanying drawing illustrates:
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the structural representation of eccentric tuningout universal ball end in this utility model.
Fig. 3 is the structural representation of universal ball end base in this utility model.
Fig. 4 is the structural representation of universal ball end upper cover in this utility model.
Detailed description of the invention:
With reference to each figure, a kind of universal deviation correcting device of oil pumping machine well head, including sucker rod body 4, connect seal box 1 and universal ball end base 3, eccentric tuningout universal ball end 7 is installed in universal ball end base 3, it is provided with anti-synchronization steel ball 5 in the steel bead groove 9 of eccentric tuningout universal ball end 7, it is provided with sealing ring 8 in the o-ring groove of eccentric tuningout universal ball end 7, it is provided with blowout prevention glueballs 2 in eccentric tuningout universal ball end 7, eccentric tuningout universal ball end 7 is outside is provided with universal ball end upper cover 6, universal ball end upper cover 6 is threadeded with universal ball end base 3, it it is dual-purpose well head attachment structure 10 bottom universal ball end base 3.
Universal deviation correcting device utilizes the eccentric position of the head of eccentric tuningout universal ball end 7, empty the inside of eccentric tuningout universal ball end 7, the diameter blowout prevention glueballs 2 more than well head minimum position is placed in the inside of hollow eccentric tuningout universal ball end 7, the requirement of blowout prevention glueballs 2 can reach required physical and chemical index, when sucker rod fractures formation blowout, blowout prevention glueballs 2 under the effect of down-hole pressure dieback in the bottom of wellhead packing box, packing box bottom design arc of specification as blowout prevention glueballs 2 cylindrical, make the contact in blowout prevention glueballs 2 certain face formed here, it coincide and reach the effect of automatic open flow in the bottom of packing box.
Owing to bias is to use three grades of trigonometric expression figures to connect to dish, can arbitrarily adjust change angle according to field condition, it is adaptable to sucker rod is eccentric without departing from the automatic deflection adjusting at any angle in the range of well head.Using eccentric tuningout universal ball end 7 and universal ball end base 3 to connect, it reaches the adjustment of longitudinal angle excursion, makes oil pumping machine well head adapt to the angle that well head is tilted by pumping unit horsehead.Universal deviation correcting device, from longitudinally, laterally without departing from adjusting in the range of well head and eccentric, fundamentally solves this difficult problem, makes sucker rod body 4 well can run when centering, thus improve the service life of sucker rod body 4；Oil pumping machine well head bias and caput Equi Asini and well head deflection is additionally made to have obtained effective control, ensure that sucker rod body 4 is in operation and remain that centering runs, sealed object in well head sealing packing box also can the most reasonably hold sucker rod body 4 tightly, reach the sealing effectiveness that wellhead packing box is good, and improve leakage efficiency.Simple in construction of the present utility model, reasonable in design, easy and simple to handle, energy-conserving and environment-protective, service life is long, and tuningout is effective.
