Abstract
The utility model provides an oil pumping machine in a type of double wobble wheels with changeable diameters, which is improved on the basis of a prime walking beam type oil pumping machine. A big wobble wheel with a variable diameter, a small wobble wheel with a variable diameter and a well head pulley are arranged on a support frame to replace a prime walking beam and a prime horse head. The big wobble wheel with a variable diameter and the small wobble wheel with a variable diameter are arranged eccentrically on a common shaft. The small wobble wheel with a variable diameter is connected with a connecting rod through a flexible member. The connecting rod is connected with a crank. The big wobble wheel with a variable diameter is also connected with a rope hanger through the well head pulley through the flexible member. Therefore, a motor drives the crank to do rotary motion through a reduction box. The connecting rod is driven by the crank. The crank drives the small wobble wheel with a variable diameter to do swing motion through the flexible member, and the big wobble wheel with a variable-diameter, which is arranged eccentrically on the common shaft with the small wobble wheel with a variable diameter, also does swing motion. The rope hanger is driven by the flexible member and the well head pulley to do seesaw motion. Thus underground liquids are lifted. The utility model has the advantages of energy saving and material saving.
Description
The utility model relates to a kind of novel double offset wobble wheels formula pumping unit, and this is the improvement to beam pumping unit.
Pumping unit be at present each oil field extensively adopt the bar oil recovery machiner arranged, it mainly is to drive pumping of oil well pump by pumping unit by sucker rod to realize the purpose of recovering the oil.Beam pumping unit is each oil field pumping unit with the most use.But this pumping unit is when stroke is longer, and himself size and weight all will increase, and power performance also may degenerate.
The purpose of this utility model is that a kind of double offset wobble wheels formula pumping unit will be provided, and when stroke is longer, the complete machine deadweight is descended, and power performance is improved significantly.
The purpose of this utility model is achieved in that on the basis of original hinge four-bar beam pumping unit, is made up of crank, connecting rod, flexible member, large and small reducing escapement, well head head sheave, support etc.Large and small reducing escapement and well head head sheave are installed at one above being installed on the other support of well head, large and small escapement is installed with eccentric shaft, big escapement is connected with flexible member with the well head head sheave, and an end of flexible member connects rope hanger by the well head head sheave, and the other end connects balance frame.Little escapement is connected with connecting rod on the crank with flexible member, and crank connects gearbox.
The utility model had both kept the critical piece and the handling characteristics of former hinge four-bar beam pumping unit, adopted big again; little reducing escapement; make the vectorial radius of drive wheel and oil well suspending point loading suitable; the moment of torsion that acts on like this on the crank reduces widely; between connecting rod and walking beam, adopt the flexible member transmission; remain Cui transmission angle (90 °) between flexible member and the little escapement thereby make; so the pivot angle of walking beam is also unrestricted; shortened the length of walking beam widely; become big; little escapement; cancelled walking beam and horse head; the complete machine deadweight descends; big or small escapement is eccentric the installation, radius is continuous variation in the rotation process, and the power performance of pumping unit has obtained obvious improvement.
Accompanying drawing is the structural representation according to double offset wobble wheels formula pumping unit provided by the utility model.
Among the figure, 1-crank, 2-connecting rod, 3-flexible member, the big escapement of 4-, the little escapement of 5-, 6-flexible member, 7-well head head sheave, 8-balance frame, 9-rope hanger, 10-motor, 11-driving belt, 12-gearbox, 13-equilibrium block.
Describe the concrete structure and the transmission process of the double offset wobble wheels formula pumping unit that proposes according to the utility model in detail below in conjunction with accompanying drawing.
Motor, gearbox, crank, connecting rod, support etc. have kept the structure of original beam pumping unit, large and small reducing escapement 4,5 and well head head sheave 7 are installed above support, big escapement 4 is installed with eccentric shaft with little escapement 5, be connected with flexible member 3 between little escapement 5 and the connecting rod 2, remain Cui transmission angle between flexible member and the little escapement thereby make.Big escapement 4 usefulness flexible members 6 connect rope hanger 9 by well head head sheave 7, and the other end connects balance frame 8.
Motor 10 is given crank 1 by gearbox 12 with transmission of power by driving belt 11, crank 1 is rotated, drive is installed in connecting rod 2 motions on the crank, driving little escapement 5 by flexible member 3 again swings, like this with little escapement 5 coaxial mounted big escapements 4 also swing thereupon, pump thereby drive rope hanger 9 by well head head sheave 7, reach the purpose of extracting down-hole liquid by flexible member 6.In order to reach good dynamical balancing effect, can on crank 1, add equilibrium block 13 or add balance frame 8 in big escapement 4 lower ends.
As calculated, the Peak torque of this kind pumping unit descends 35% than beam pumping unit, and it is about 20% that energy consumption and deadweight descend, and the stressed of the connecting rod of main member also reduces by 25%.Therefore, the utility model be a kind of energy-conservation, economize material, new pumping unit that economic benefit is high.
Claims (3)
1, a kind of double offset wobble wheels formula pumping unit, form by gearbox, crank, connecting rod, flexible member, big or small reducing escapement, well head head sheave, support etc., it is characterized in that, big or small reducing escapement (4,5) and well head head sheave (6) are installed above support, be connected with flexible member (3) between little escapement (5) and the connecting rod (2), big escapement (4) connects rope hanger (9) with flexible member (6) by well head head sheave (7).
