Abstract
The invention relates to a single-reversing oil pumping unit with triangular chains. The single-reversing oil pumping unit comprises a reversing turning wheel, a weight basket, a sucker rod and a reversing mechanism. A steel wire rope is wound across one end of the reversing turning wheel to be connected with the sucker rod, and the other end of the steel wire rope is connected with the reversing mechanism through the weight basket. The reversing mechanism comprises a fixing rack and a lifting power mechanism arranged on the fixing rack. The lifting power mechanism comprises first front and rear upper-right positioning adjustment chain wheels, second front and rear upper-left positioning adjustment chain wheels, first front and rear lower-right large positioning guiding chain wheels, second front and rear lower-left large positioning guiding chain wheels, first front and rear lower-right small positioning guiding chain wheels and second front and rear lower-left small positioning guiding chain wheels. The single-reversing oil pumping unit has the advantages that since the triangular lifting power mechanism is adopted, the sucker rod can stay for 4-5 seconds when running to the horizontal chains, accordingly the sucker rod can have the time to retract, the oil pumping time is much longer than the non-oil pumping time, the oil pumping efficiency is effectively improved, and the oil pumping quantity is effectively increased.
Description
Technical field
The present invention relates to pumping unit technical field, more particularly to a kind of triangle chain monodromy is to oil pumper.
Background technology
For a long time, China's oil field development mainly adopts beam pumping unit, although beam pumping unit reliability is high,
Its operational efficiency is low, and energy consumption is big so that crude oil development high cost, it is impossible to adapt to the demand of energy-saving development, and conventional type
Oil pumper is difficult to long stroke and big load.
At present during oil extraction in oil field, the closed box body oil pump of employing due to circulation link chain be single composition to circulation
Motion, only one of which circulation axis during the upper and lower operation of sucker rod, but and causes sucker rod elasticity to draw making average rate shuttling movement
It is long, sucker rod toward the oil that an anti-pump drainage is put on ground only have in pipe 35%, the Action of Gravity Field of ballast box is uniquely being followed
On annulate shaft, circulation axis discontinuity at the volley causes rattle big, and circulation axis is easily destroyed.
In order to solve the above problems, Chinese patent 201520029504.6 discloses a kind of symmetrical cycle chain drive pumping unit and passes
Dynamic device, the front left of this device, the front chain of front right circulation link chain are vertical, rear left, rear right
The rear chain of circulation link chain is vertical;The inside chain of front left, front right circulation link chain and rear left, rear right circulation link chain
It is symmetrical circulation link chain in the diagonal, because the Action of Gravity Field of ballast box is on forward and backward reversing shaft, in front and back the gravity of reversing shaft divides
Do not act on front left, front right circulation link chain and rear left, on rear right endless-chain, when driving shaft rotates, enter left and right drive sprocket
Row is rotated, and due to the rotation of left and right drive sprocket, makes left and right driving chain be synchronized with the movement;Because left and right driving chain is made
Be synchronized with the movement, make front left, front right, rear left, rear right drive sprocket, front bottom left, front bottom right, rear bottom left, rear bottom right circulation sprocket wheel and
Front left, front right, rear left, rear right circulation link chain and forward and backward reversing shaft make symmetrical shuttling movement, when forward and backward reversing shaft is moved to
Endless-chain
When on the vertical line of bar, well bar makees falling motion, and well bar makees falling speed increasing;When reversing shaft moves to circulation link chain
During the line of dip, well bar runs up and slows down, although this structure each run, make time of oil pumping more than non-oil pumping when
Between, can be with energy-conservation, although this device improves certain oil pumping amount, but also some liquid measure can not be returned in oil pick-up tube
Receive.
