Abstract
The invention provides a lubrication-free chain oil pumping unit for oil production in an oil field. The lubrication-free chain oil pumping unit comprises a frame, a motor, a speed reducer, a belt pulley, a transmission chain wheel, a lubrication-free chain, upper and lower transmission pulley blocks, a stroke regulating plate, a counterweight and a lifting cable, wherein the lubrication-free chain is adopted in the oil pumping unit; and a high-polymer polyethylene plastic bearing is arranged between sliding bodies, and lubrication is not required during use. A shaft of a speed reducer is used for driving double chain wheels, so that synchronous movement of double chain wheels on both sides of the oil pumping unit is ensured, and the double chain wheels on both sides are stressed uniformly. The counterweight is connected with a synchronizing shaft across a pulley through a rope, so that the problem of swinging during ascending and descending of the counterweight is solved, the influence of the counterweight on the synchronizing shaft is only in the vertical direction, and the influence of side bending moment, which is generated by swinging of the counterweight, on the synchronizing shaft is isolated. Moreover, the impact on the synchronizing shaft caused by variation of the length of a closed ring total rope consisting of a transmission cable is eliminated, and the oil pumping unit runs smoothly; and standard pieces or standard structural pieces are adopted, so that high universality is achieved.
Description
Technical field
The present invention relates to a kind of oil extraction in oil field with exempting from lubricating chain formula oil pumper.
Background technology
At present, it is conventional beam-pumping unit that the adopting of underground oil and gas is drawn device widely used, although it is simple, reliability and durability and be convenient to the advantages such as maintenance that it has structure, be more and more difficult to satisfied present deep-well, heavy oil wells to the requirement of oil pumper long stroke, large load.In this case, start to adopt chain type oil pump.Chain type oil pump has that stroke is long, inertial load is little, quality and the advantage such as floor space is little.From the situation that current oil field uses, affect chain type oil pump further genralrlization use main cause be: reliability is poor, chain rapid wear, and the failure-free operation cycle constantly shortens, have less than half a year; Add and will stop maintenance, workload is large, and costly, applying unit is difficult to bear.Cause the reason that chain type oil pump reliability is low, one is because chain motion is asynchronous, produces a sizable lateral bending moment on chain, stressed large side premature deterioration; Two is that the swing of balance weight on the normal plane of chain movement track produces a lateral bending moment, causes local chain link to destroy; Three is that chain uses for a long time and can not get good lubrication, accelerated wear test, the lost of life.(bibliography: Chinese patent CN101307683, symmetrical balance chain type oil pump; Chinese patent CN2799902, chain drive pumping unit; Chinese patent CN101469606, chain type oil pump; Chinese patent CN2199330, without the chain type oil pump of reversing gear bracket; Chen Yibao, high peace, Zhang Shaobo, stone face punt-pole, Zhang Huiwen, Tang Lijie., without the principle and characteristics of reversing gear bracket chain drive pumping unit. petroleum machinery, 1996,24 (5), 42-44; Yang Chongen. the schematic design of long stroke Double chain synchronous drive oil pump. petroleum machinery, 2001,29 (8): 10-12.)
