Abstract
A gear converted oil pumping device characterizes in utilizing the invented interchange unit of to-and-fro movement and rotary moving gear to turn the high rotary motion power to the to-and-fro output omving power by a gear conversion unit then to connect the wire rope with the feeding rod and the sucker rod by torque conversiong ear, rack bar and binged wheel then to drive the plunger of the pump of work up and down to-and-fro by the sucker rod which can save energy 30% over than the current technology.
Description
The present invention relates to a kind of sucker-rod pumping device, especially a kind of rod pump gear type conversion oil rig.
At present, widely used sucker-rod pumping device is one of traditional oil production method of petroleum industry, also is prevailing always artificial lift mode in the petroleum production engineering.Sucker rod pumping comprises conventional sucker rod pumping and screw pump oil production, and the both gives underwell pump by pumping unit with the ground transmission of power; The former is that the to-and-fro motion with the pumping unit suspension point passes to the down-hole plunger pump by sucker rod, and the latter passes to subsurface progressive cavity with rotatablely moving of well head driving head by sucker rod.Conventional sucker-rod pumping device comprises the oil pumping system that pumping unit, sucker rod and oil well pump are formed, it utilizes the connecting rod of pumping unit, rotatablely moving of power engine (motor or natural gas engine) become the to-and-fro motion of polished rod, and the plunger that drives deep-well with sucker rod is pumped.
Pumping unit is the capital equipment of sucker rod pumping, and pumping unit is divided into beam pumping unit and no beam pumping unit again by its basic structure; Beam pumping unit mainly is made of walking beam, connecting rod, crank mechanism, belt pulley, speed reducer, power equipment and supplementary equipment, during work, the high speed rotary motion of power engine, pass to crankshaft by belt and speed reducer, drive crank and make low-speed rotation, crank drives walking beam by connecting rod through crossbeam and swings up and down; The rope hanger that hangs on the horse head just drives polished rod and the to-and-fro motion up and down of sucker rod do.The major defect of this pumping unit is: the first, owing to need long crank radius, crank radius is directly proportional with the reciprocating stroke of rope hanger, and horse head one end of walking beam is generally less than crossbeam axle one end, add crankshaft balance weight and walking-beam counterweight, be consumed in the inertial force of displacement, moment of inertia, link motion component, the power that consumes in leverage power and self transmission process accounts for more than 50% of power engine power; The second, the space that accounts for is big, and to horse head, rope hanger, from the base to the walking beam, the space that accounts for reaches 300-500M from power engine, speed reducer
3The 3rd, weight is big, and the raw material of consumption are many; The 4th, the power discharge capacity is low, increases cost for oil production.
The present invention is a kind of rod pump gear type conversion oil rig that provides for the shortcoming that overcomes above-mentioned technology.
The object of the present invention is achieved like this, use my patent of invention to-and-fro motion and rotary motion gear type interchange mechanism, the patent No.: ZL96117438.2, make the power of power engine pass through speed reducing gear pair, enter the rotation motion reciprocating mechanism, this mechanism is by two complete all gears, compound two half cycle circular arc rollers wheel, two half cycle circular arc roller wheels alternately mesh with Jie's circular tooth gear, by the bending moment wheel and rack engagement coaxial with Jie's arc gear, export reciprocating power from tooth bar, the lower end of tooth bar is connected with polished rod by connector, pass through packing box, three-way valve is connected with sucker rod, sucker rod drives the plunger of plunger pump and does the operation of oil recovery up and down reciprocatingly, perhaps transform the bending moment gear into the U-groove bevel reel, be connected with the bottom land of U-groove bevel with wire rope one end, walk around the crown sheave the other end and be connected, make oil producing operation up and down reciprocatingly by the plunger of sucker rod drive plunger pump again with polished rod.
A kind of rod pump gear type of the present invention conversion oil rig has following advantage compared with the prior art:
1, saves energy consumption, the power that rotatablely moves from power engine input, export reciprocating power to tooth bar, have only 4 pairs of gear pair transmissions therebetween, machining accuracy is than higher gear pair transmission, a pair of gear pair autophage power has only 0.5%-1.5%, and the power of autophage is very low, can save energy consumption 40%.
2, volume-diminished, the space of whole machine installation only needs 100m
3-150m
3, can dwindle 2-3 doubly.
3, weight reduces about 50%, saves raw materials consumption, reduces manufacture cost.
4, easily damaged parts reduces, and prolong working life.
5, because stability and reliability have improved in aboveground mechanism, can improve the volumetric efficiency and the discharge capacity of pump.
6, improving the power ratio discharge capacity, reduce the cost of sucker rod pumping, is the novel sucker-rod pumping device of a generation.
Below in conjunction with drawings and Examples, the invention will be further described:
