Description
Technical field
A kind of oil-field oil pumper packing box is the utility model is related to, belongs to petroleum machinery oil pumper equipment technical field.
Background technology
Pumping unit well mouth polish rod sealed packing box is the important component for being connected rod-pumped well lower tubular column and oil pumper, is oil pumping
Motor-pumped well production management and the key point of system power consumption.Xian Ge oil extraction in oil field factory's oil extractor packing box in prolonged oil pumping production and
Oil is run in wear process, at sealed packing to become increasingly conspicuous, and mostly spurting, run oily pollution environment.Thus the problem of triggering is very
More such as:Waste petroleum resources, the maintenance cost of packing is changed in increase, causes producing region large area crude oil pollution, the person of adding
Work recovers the working strength of environment, and recovery process is complicated, loses time, influences oil well output.
Existing rod-pumped well packing box generally using the packing box of primary seal packing, mainly manually adjusts formula
Packing box, its structure member are made up of gland, housing, piston, rubber packing and packing supporting plate.
Oil pumping machine well head sealing is by rotatable handle gland, promotes descent of piston, extrudes rubber packing, makes rubber packing
Certain deformation occurs, inner hole is brought into close contact with polished rod and keeps certain pressure, and then the sealing to well head is realized together with polished rod.
Wellhead packing box run it is oily the main reason for be:
Burn into excoriation occurs for polished rod:In order to prevent oil leak, worker will use very big strength extruding rubber packing,
The pressure of rubber packing and polished rod increases, and frictional force increase, polished rod lubricant effect is deteriorated, the rise of polished rod surface temperature, polished rod
When descending, crude oil cools down to polished rod again, and polished rod surface carries out the process of heating and cooling repeatedly like this.Polished rod simultaneously
Surface is extruded repeatedly, reduces the fatigue strength on polished rod surface, polished rod epidermis is cracked, comes off, corroded, with the corruption of polished rod
Erosion, excoriation aggravation, polished rod surface is no longer smooth, and coarse polished rod wears to packing, isolated, and well head packing at this moment is easy
Oil is run in generation.
Polished rod is bent:Certain bending can occur among the course of work for some polished rods, and the polished rod of bending rises in oil pumper
When taking out, to packing well damage.
Polished rod thickness is uneven:Polished rod occurs abrasion and occurs that oval, thickness is uneven, or in one section of thick one section thin wave feelings
Condition, the sealing of such packing can be deteriorated, and well head occurs and runs oil.
Polished rod misaligns with packing box:Polished rod misaligns the axis for referring to polished rod with packing box and packing box axis does not weigh
Close, the damage misaligned to rubber packing is extremely serious, if misalign it is serious if, rubber packing can be quickly to simultaneously grinding away
And sealing is lost, well head occurs and runs oil.
Polished rod rocks:Polished rod does not move along a straight line when pumping, but shakes, and the destruction to packing is non-
Chang Yanchong.
The content of the invention
In order to overcome above-mentioned technical deficiency, the utility model provides a kind of novel oil pumping machine of oil field packing box, the disk
The core component of root box is the blowing pressure cushion rubber, and it can effectively solve the problem that packing box compression, lubrication, tuningout, profiling, rocks and follow
Deng technical barrier.
Technical scheme is used by this practical utility model solves its technical problem:Its structure of oil extractor packing box is:
Upper end of joint is eccentric structure, and well head of the joint screw thread connection with crude oil, upper end of joint outer rim inboard is provided with rubber blanket groove, glue
Rubber cushion is equipped with pad groove;Housing lower end is provided with the eccentric tongue that is engaged with rubber cushion groove, and housing upper end is provided with external screw thread, in gland
Side is provided with the internal thread supporting with housing external screw thread, and handwheel, spiral shell of the housing lower end with joint by circle clamp are provided with the outside of gland
Bolt is fastenedly connected;Upper end of joint in housing is equipped with lower rubber ring, and lower rubber ring upper end is equipped with the blowing pressure cushion rubber, the blowing pressure
Cushion rubber is annulus body, and pressure cushion rubber one end is provided with check valve, and pressure cushion rubber is interior filled with gas;On the inside of pressure cushion rubber outside sucker rod
Side is equipped with packing, and pressure cushion rubber and packing upper end are equipped with upper rubber ring, and upper rubber ring upper end is equipped with lower spring cup, on lower spring cup
End is equipped with spring, and machine oil is filled around spring and sucker rod, and spring upper end is equipped with upper spring seat, and the internal thread of gland screws in housing
External screw thread, by adjusting progressively holddown spring.
The beneficial effects of the utility model are:Housing is rotated, by the adjustment of housing and the eccentric structure of joint, makes packing
Box can ensure and light-rod coaxial, avoids the undue eccentric wear of polished rod.Polished rod is in motion process, it may appear that certain bias, by
The gas of flowable is filled with inside rubber pressure circle, makes packing follow polished rod eccentric together, realizes bias without inclined
The effect of mill.If polished rod has certain bending, due to the corrective action of gas inside rubber pressure circle, packing also can be with light
The bending of bar and bend, prevent excessive wear.Rocked for polished rod, also because the corrective action of rubber pressure circle the inside gas,
Packing rocks also with rocking for polished rod, avoids excessive wear.It is uneven for polished rod ellipse, thickness or one section thick one section thin
Situation, due to being with certain pressure, compressible, flowable gas inside rubber pressure circle, hole can be with light in packing
The change in bar section and change, while the blowing pressure cushion rubber gas pressure makes the packing moment be bonded with polished rod, and in all directions
Identical pressure is kept to polished rod, it is therefore prevented that the leakage of oil gas.For high-pressure well, the oil gas inside well casing produces to lower rubber ring
Upward pressure, compressive charge pressure cushion rubber make pressure increase inside the blowing pressure cushion rubber, and compression packing is close to polished rod, anti-stopping leak
Dew.Butter reduces friction, reduces bare rod corrosion.Butter is filled with outside pressure cushion rubber, in the course of work, because polished rod is to disk
The continual extruding of root, promote, gradually butter can be lubricated to promotion at packing, butter through packing to polished rod, light
There is one layer of oil film on bar surface all the time, reduces friction, reduces corrosion, extends the service life of polished rod.The pressure of packing and polished rod
Clamp force reduces, and reduces frictional force, reduces energy consumption.
