Abstract
An original packing box for a wellhead and a pumping unit does not have a deviated alignment function, wherein a rigid connection is formed between the packing box and the wellhead, and sealing is implemented by a strong pressure. A universal alignment packing box is capable of implementing two times of deviated alignment, wherein planar alignment can be implemented by the first time of deviation; and parallel alignment is implemented by the second time of deviation. In this way, efficient sealing can be implemented during the parallel alignment without a strong pressure; static friction force is reduced; and energy consumption is reduced. A tower-shaped spring and a spring wide plate are designed in the packing box so as to scrape thick oil and prevent liquid pressures from damaging rubber packing. The universal alignment packing box has four effective functions including universal, planar and parallel alignment, reduction of the static friction force, reduction of the energy consumption, scraping of the thick oil, and protection of the rubber packing. The universal alignment packing box is the most rational and effective design at present.
Description
Technical field
The present invention relates to petroleum recovering equipment, be a mechanical part of petroleum extractor pithead position.
Background technology
Past packing box and petroleum extractor well head are rigid joints, do not swing to function.Caput Equi Asini and well head away from
Away from from, well head centering is gross data, actual be extremely difficult to entirely on the center.Separately install due to manual operation
Well head degree of accuracy, down-hole have hole deviation, height sedimentation these situations uneven of aboveground oil pumper make well head difficult
With centering.And the combination of polished rod and well head also because of above-mentioned reason not on parallel lines, angle of arrival.I.e.
Make centering that one point to occur, but do not reach absolutely the sealing of the parallel surface that needs reach.So oil oil pumping
The well head stiction of machine is very big, accelerates the loss rate of well head packing, and strengthens its power consumption.
The utilization of universal centering this mechanical part of packing box of my invention just solves problem above.
Summary of the invention
Past packing box and petroleum extractor well head are rigid joints, do not swing to function.Caput Equi Asini and well head away from
Away from from, well head centering is gross data, actual be extremely difficult to entirely on the center.Separately install due to manual operation
Well head degree of accuracy, down-hole have hole deviation, height sedimentation these situations uneven of aboveground oil pumper make well head difficult
With centering.And the combination of polished rod and well head also because of above-mentioned reason not on parallel lines, angle of arrival.I.e.
Make centering that one point to occur.But do not reach absolutely the sealing of the parallel surface that needs reach.
The arbitrarily deflection of the most universal centering packing box hands over positive centering, thoroughly solves well head centering problem, solves
The problem of polished rod and well head angle of arrival, makes polished rod be in operation and well head presents the sealing of parallel surface, carry
High sealing effectiveness, reduces stiction.
2. the design of spring packing solves the impact failure to rubber packing of the internal pressure in oil pipe, makes rubber
Packing extends service life.
3. the design of spring packing box can scrape off viscous crude completely at viscous oil area.
Everything centering packing box is the most effective design.

Specific embodiments
Connect rubber packing box above the universal centering packing box of my invention, connect well head below.It solves
Well head centering problem, the problem solving polished rod and well head angle of arrival, make polished rod be in operation and well head
Present the sealing of parallel surface, improve sealing effectiveness, reduce stiction；Also solve liquid in oil pipe
The internal pressure impact failure to rubber packing, make rubber packing extend service life；Can at viscous oil area
Completely viscous crude is hung.
Claims (1)
1. the invention of this packing box is applicable to petroleum extractor, is arranged on below packing box.Past packing box and stone
Oil oil pumping machine well head is rigid joint, does not swing to function.Caput Equi Asini is remote with well head distance, and well head centering is simply
Gross data, actual be extremely difficult to entirely on the center.Separately have due to manual operation installation well head degree of accuracy, down-hole
Hole deviation, the height sedimentation the most individual situation of inequality of aboveground oil pumper make well head be difficult to centering.And polished rod with
Well head combination also because of above-mentioned reason not on parallel lines, angle of arrival.Even if there is a point in centering,
But do not reach absolutely the sealing of the parallel surface that needs reach.
