Abstract
The utility model provides a kind of plural equilibrium vertical oil-pumping machine, mainly it is made up of base, pylon, balance weight, steel wire rope, motor, belt, head sheave, guide wheel, the frame that is rigidly connected, sucker rod, well head, hydraulic cylinder, piston, piston rod, stop production at regular intervals to solve vertical oil-pumping machine, staff adjusts the problem of balance weight is to match load change.Its technical scheme is：Guide wheel is connected by the left sibling of the frame that is rigidly connected below steel wire rope with sucker rod, at the same time, and guide wheel is also connected by the right node for the frame that is rigidly connected with hydraulic cylinder.The beneficial effects of the utility model are as follows：Hydraulic cylinder energy storage is utilized during sucker rod down stroke, hydraulic cylinder releases energy during sucker rod upstroke.By this hydro-cushion mode to match load, the purpose for automatically adjusting balance is realized, the workload of well site personnel is alleviated, the production of crude oil is improved.
Description
Technical field
The utility model is related to a kind of oil pumper, more particularly to a kind of plural equilibrium vertical oil-pumping machine.
Background technology
Vertical oil-pumping machine is tower-type structure, is now widely used for viscous crude, height and coagulates opening for oily and deep-well hyposmosis crude oil
Adopt and oilfields in high water cut period crude oil production, it is small with floor space, the advantages of efficient low-consume, meet it is deep take out, save and
The technological requirements such as huge discharge extract.However, oil pumper is in the course of the work, the load meeting in upstroke and down stroke at sucker rod
Change, oil pumper has to stop production at regular intervals, consequently facilitating well site personnel adjust balance weight to match load
The change of lotus, this has not only aggravated the workload of well site personnel, the production of oil well is also have impact on to a certain extent, life is added
Produce the cost of operation.
Utility model content
The problem of to solve frequently adjustment balance weight, the utility model provides a kind of plural equilibrium vertical oil-pumping machine, i.e.,
Hydraulic cylinder is installed on the basis of existing vertical oil-pumping machine, down stroke energy storage is realized using hydraulic cylinder, upstroke releases energy, and reaches
To the effect for automatically adjusting balance, it is simple efficiently, it is easy to operate, save the production time, it is to avoid what balance weight was periodically adjusted
Trouble.
The utility model provides a kind of plural equilibrium vertical oil-pumping machine, including base, pylon, balance weight, steel wire rope, electricity
Machine, belt, head sheave, guide wheel, the frame that is rigidly connected, sucker rod, well head, hydraulic cylinder, piston, piston rod.Its technical scheme is：It is described
Pylon is fixed on the base, and motor is installed on pylon, and the motor is connected by belt with the head sheave, and the head sheave is left
End is connected by the steel wire rope with guide wheel, and the head sheave right-hand member is connected by steel wire rope with the balance weight, and the guide wheel leads to
The left sibling for the frame that is rigidly connected crossed below steel wire rope is connected with sucker rod, and the sucker rod is arranged on well head, described to lead
Wheel is connected by the right node of the frame that is rigidly connected below steel wire rope with the hydraulic cylinder.
The utility model plural equilibrium vertical oil-pumping machine structure design advantages of simple, convenient operation.In sucker rod down stroke
When, the sucker rod that there is deadweight is moved downward so that hydraulic cylinder stores portion of energy, in sucker rod upstroke, hydraulic cylinder
This portion of energy is discharged again, the function of this automatic energy storage exoergic of hydraulic cylinder solves frequently asking for adjustment balance weight
Topic, realizes the purpose for automatically adjusting balance, reduces the workload of well site personnel, improve the production of crude oil.
Brief description of the drawings
A kind of structural representation for plural equilibrium vertical oil-pumping machine that Fig. 1 provides for the present invention.
In figure：1 base；2 pylons；3 balance weights；4 steel wire ropes；5 motors；6 belts；7 head sheaves；8 guide wheels；9 are rigidly connected frame；
10 sucker rods；11 well heads；12 hydraulic cylinders；13 pistons；14 piston rods.
Embodiment
The structural representation shown in 1 is further described through to the utility model below in conjunction with the accompanying drawings：
As shown in figure 1, the utility model provides a kind of plural equilibrium vertical oil-pumping machine, it is mainly by base 1, pylon 2, flat
Weight 3, steel wire rope 4, motor 5, belt 6, head sheave 7, guide wheel 8, the frame 9 that is rigidly connected, sucker rod 10, well head 11, hydraulic cylinder 12, work
Plug 13, piston rod 14 are constituted.Base 1 is fixed on ground, and pylon 2 is fixed on base 1, and motor 5 is provided with pylon 2 and is passed through
Belt 6 is connected with head sheave 7, and the left end of head sheave 7 is connected by steel wire rope 4 with guide wheel 8, and the right-hand member of head sheave 7 passes through steel wire rope 4 and balance weight
3 are connected, and guide wheel 8 is connected by the left sibling of the frame 9 that is rigidly connected of the lower section of steel wire rope 4 with sucker rod 10, and guide wheel 8 passes through steel wire rope
The right node of the frame 9 that is rigidly connected of 4 lower sections is connected with hydraulic cylinder 12, and sucker rod 10 is arranged on well head.
During 10 down stroke of sucker rod, moved downward by the Action of Gravity Field of itself, motor 5 is rotated counterclockwise, the band of steel wire rope 4
Dynamic balancing weighs 3 motions upwards, and balance weight 3 stores part energy, at the same time, and hydraulic cylinder 12 is compressed also to store part energy
Amount；When 10 upstroke of sucker rod, motor 5 is rotated clockwise, and steel wire rope 4 drives balance weight 3 to move downward, and is stored up in balance weight 3
The energy deposited is discharged, at the same time, and the portion of energy that hydraulic cylinder 12 is stored also is discharged；Hydraulic cylinder is in down stroke and upper
There is the effect of automatic energy storage and exoergic in stroke procedure, so as to reach the effect of autobalance load, production fortune is reduced
The cost of battalion.
