Abstract
A kind of dynamic balance beam pumping unit, it is characterized in that setting an intermediary wheel above bearing support, driving rope bypasses two ends after driving wheel, intermediary wheel and directive wheel and is connected respectively on the horse head for hanging ballast box and hangs on the horse head of sucker rod successively, one is flexibly connected above oil pumping unit base and drives platform, motor, decelerator and driving wheel are all disposed within driving platform, and a sandbox is set below driving platform.Weight of the invention by adjusting sandbox, when the oil pumper is normally run, the half of the nearly oil column weight of differential of the driving rope pilled-in selvedge on driving wheel both sides and the power of slack list, then the tractive force subtractive of two horse heads in complete machine is small, at this moment driving rope overcomes a part of frictional force and worked, therefore energy-saving effect is produced, oil pumper abrasion is reduced, extends oil pumper service life.
Description
Technical field
The present invention relates to a kind of oil recovery machiner, more particularly, to a kind of dynamic balance energy-saving sliding beam type pumping unit.
Background technology
In the case of energy scarcity, electric power wretched insufficiency, energy-conservation turns into critically important subject under discussion.Oil pumper is that oil field is main
Production equipment, for low-permeability oil field, oil level forms slow, and most of oil pumper is for a long time all in idle running, and this will
A large amount of electric energy are wasted, and cause oil pumper to wear and tear, the oil pumper life-span is reduced.
At present, the oil pumper commonly used both at home and abroad has two kinds of beam pumping unit and balance type beam-pumping unit.Common beam
The performance comparision of formula oil pumper is reliable, but it is larger to consume energy.Balance type beam-pumping unit operates steadily, and consumes energy compared with beam pumping unit
It is few but preferable not enough.Its drive part is fixed on oil pumping unit base, and sucker rod is arrived when the weight of counterweight of oil pumping unit case is set
When weight adds oil column weight half, when no matter sucker rod rises or declined, the difference of the tractive force on two symmetrical horse heads is all
It is the half of oil column weight, therefore both sides are never balanced, power consumption is big, requires far apart with national energy-saving, oil pumper mill
Increase is damaged, the oil pumper life-span is reduced.
The content of the invention
The problem of technical problems to be solved by the invention are big existing oil pumper power consumption, serious wear, low life-span, so that
A kind of dynamic balance beam pumping unit is provided.
In order to solve the above technical problems, the present invention provides a kind of dynamic balance beam pumping unit, mainly include oil pumper bottom
Seat, bearing support, walking beam, hang ballast box horse head, hang sucker rod horse head, ballast box, sucker rod, oil pick-up tube, electrical control cubicles, motor,
Decelerator, driving wheel, directive wheel, supporting are erected on oil pumping unit base, bearing support top connection walking beam, and walking beam two ends connect respectively
Connect extension ballast box horse head and hang sucker rod horse head, motor is connected successively with decelerator and driving wheel, it is characterised in that：Branch
Set an intermediary wheel above bolster, driving rope bypasses two ends after driving wheel, intermediary wheel and directive wheel and is connected respectively to extension counterweight successively
On the horse head of case and hang sucker rod horse head on, above oil pumping unit base be flexibly connected one drive platform, motor, decelerator and
Driving wheel is all disposed within driving platform, and a sandbox is set below driving platform.
Drive platform that one hinge axis is installed below by two bearing blocks, the two ends of hinge axis are fixed on oil pumping unit base
Bearing shell fixator on.
Driving platform is connected to above oil pumping unit base and one end away from driving wheel, and sandbox is arranged on below driving platform
Positioned at driving wheel one end.
The difference of the driving force of driving wheel both sides driving rope is 1/2 oil column weight.
The present invention is by adjusting the weight of sandbox, and when the oil pumper is normally run, driving platform around hinge axle is rotated, driving
There is difference in the driving force of the driving rope on wheel both sides, then the tractive force difference of two in complete machine horse head is corresponding reduces, and at this moment drives
Rope overcomes a part of frictional force and worked, therefore produces energy-saving effect, reduces oil pumper abrasion, and extension oil pumper uses the longevity
Life.When driving force difference is 1/2 oil column weight, the tractive force of two horse heads in complete machine is equal, reaches balance, energy-saving effect is most
It is good.
