The asynchronous balanced positive torque oil pumping unit is characterized by comprising a driving crank rotary shaft (1), wherein the driving crank rotary shaft (1) is connected with a driving crank balancing weight (11) through a driving crank (14); the driving crank (14) is divided into two sections which are connected through a rotary shaft; a connecting rod (2) is connected between the rotary shaft of the driving crank and the rotary shaft of a driven crank movable pulley (3). The asynchronous balanced positive torque oil pumping unit has the characteristics of small load impact, high system efficiency and low energy consumption.
Description
Technical field
The utility model relates to the oil extraction in oil field field, the asynchronous balance positive-torque oil pumping machine of especially a kind of employing three counterweights, four-throw.
Background technology
At present, the oil extraction in oil field mode comprises plunger displacement pump, screw pump, electric submersible pump, hydraulic pump, gaslift etc. both at home and abroad.Wherein, sucker-rod pumping technique still occupy space of top prominence in all kinds of artificial lift oil production methods.，Chu Middle East, oil field, whole world majority is outside flowing well, most sucker rod pumping technology that adopt, the oil well of the whole world more than 75% used the sucker rod pumping mode, the nearly 400,000 mouthfuls of wells of China, except screw pump, electric immersible pump well account for 25%, rod-pumped well has 250,000 mouthfuls more than.But to be fluctuating load large and exist the negative torque negative power to cause the problems such as system effectiveness is low, energy consumption is large for current pumping well system, the subject matter of existence.
Summary of the invention
In order to overcome the deficiency that existing beam pumping unit fluctuating load is large, system effectiveness is low, the utility model provides a kind of asynchronous balance positive-torque oil pumping machine, and this asynchronous balance positive-torque oil pumping machine has the advantages that load impacting is little, system effectiveness is high, power consumption is few.
The technical solution of the utility model is: a kind of asynchronous balance positive-torque oil pumping machine, comprise driven crank shaft, on driven crank shaft, be connected with driven moveable pulley for single-crank, also comprise the driving crank rotating shaft, the driving crank rotating shaft connects the driving crank balancing weight by driving crank, and driving crank is two sections, by rotating shaft, connects between two sections, be connected with connecting rod between its rotating shaft and driven moveable pulley for single-crank rotating shaft.
On described driven moveable pulley for single-crank, be wound with wire rope, an end of wire rope is by well head fixed pulley connecting with pumping rod, other end connecting steel wire ropes locking bed.
The utlity model has following beneficial effect: owing to taking such scheme, outside driven crank shaft, increase the driving crank rotating shaft, driving crank, driving crank and the uniform rotation of driving crank balancing weight, driven crank speed change is rotated, upstroke speed is reduced, peak load reduces, down stroke speed is increased, minimum load increases, namely utilize barycenter trajectory and the past multiple equilibria of well head balance weight of driving crank balancing weight and driven crank balancing weight, mating with load phase together of comprehensive each counterweight center of gravity, reduce fluctuating load, thereby realize omnidistance positive-torque, improved the operating efficiency of oil pumper.And this Pumping Unit is compact, take up an area less, simplify on basis, and rotating moving part all is enclosed between fixture, realizes the running safety of field unattended.
The accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is schematic diagram of the present utility model.
1-driving crank rotating shaft in figure, 2-connecting rod, the driven moveable pulley for single-crank of 3-, the driven crank shaft of 4-, 5-wire rope locking seat, 6-wire rope, 7-connects the device of restricting, 8-well head fixed pulley, 9-sucker rod, 10-well head, 11-driving crank balancing weight, the driven crank balancing weight of 12-, 13-well head balance weight, 14-driving crank.
The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing:
By Fig. 1, shown in 2, a kind of asynchronous balance positive-torque oil pumping machine, comprise well head 10, sucker rod 9, driven crank shaft 4, driven crank shaft 4 connects driven crank balancing weight 12 by driven crank, driven crank is two sections, between two sections, connect by rotating shaft, in rotating shaft, also be connected with driven moveable pulley for single-crank 3, on described driven moveable pulley for single-crank 3, be wound with wire rope 6, the left end of wire rope 6 is connected with the device 7 of restricting, connect the left end of the device 7 of restricting by well head fixed pulley 8 connecting with pumping rods 9, the right-hand member connecting steel wire ropes locking bed 5 of wire rope 6, a side relative with sucker rod 9 on well head fixed pulley 8 is connected with well head balance weight 13.This oil pumper also comprises driving crank rotating shaft 1, driving crank rotating shaft 1 connects driving crank balancing weight 11 by driving crank 14, and driving crank 14 is two sections, by rotating shaft, connects between two sections, be connected with connecting rod 2 between the rotating shaft of its rotating shaft and driven moveable pulley for single-crank 3.
According to force analysis, the pin joint place of driving crank 14 is subject to power F
3Upwards component, driving crank counterweight block 11 be subject to in lower gravity F
2, the power that driving crank rotating shaft 1 is moved is F
3, F
2Make a concerted effort, because two power are opposite at vertical direction, so it is less to make a concerted effort, reasonable stress.In like manner, driven moveable pulley for single-crank 3 is subjected to force direction opposite with driven crank balancing weight 12 gravity direction in the vertical directions, the suffered minimum of making a concerted effort of driven crank shaft 4.Like this, driving crank rotating shaft 1, driven crank shaft 4 load are little, save material, life-extending.Well head balance weight 13 can utilize sandstone to regulate, and cost is low, easy to adjust.
During oil pumper work, speed reducer output shaft drives driving crank 14 and rotates around driving crank rotating shaft 1, by connecting rod 2, driving driven crank rotates around driving crank rotating shaft 4, driven moveable pulley for single-crank on driven crank pulls wire rope 6, because wire rope locking seat 5 is fixedly dead points of wire rope, wire rope pulls sucker rod 9 to move up and down by fixed pulley 8, realizes reciprocal reciprocating oil pumping; Simultaneously, by well head fixed pulley 8, increase well head and join piece 13, regulate according to each well concrete condition the weight that well head is joined piece 13, fractional load while carrying out the balance upstroke, reduce load impacting, thereby realize the omnidistance positive-torque work of oil pumper.Simultaneously, this pumping unit system is simple and compact for structure, simply take up an area less on basis, easy for installation, and rotating motion part is enclosed between fixture, thereby realizes the running safety of field unattended.
