Abstract
The present invention relates to the adjustable variable moment type slide beam balancing method for oil pumping unit. The method is that one slide beam moment varying and balancing regulator is increased on the slide beam of the oil pumping unit. While the oil pumping unit operates, the increased slide beam moment varying and balancing regulator is used to alter the distance from the balance weight to the middle shaft of the slide beam to realize the balance of variable moment slide beam. The method is novel and feasible, and the balancing regulator has simple structure, light weight, less material consumption, convenient operation, high safety and high reliability.
Description
Technical field:
The present invention relates to a kind of mechanical balance method of adjustment that is used for the oil-field oil pumper course of work, belong to the mechanical oil recovery class.
Background technology:
So far for a long time, beam pumping unit is the main oil recovery machiner that oil field development crude oil production process is adopted always.A major issue in the pumpingh well production and the beam-pumping unit course of work is the mechanical balance of oil pumper when how to keep the upper and lower stroke of rod string.At present, the mechanical balance system that on-the-spot oil pumper adopts mainly is a crank balance, secondly also can adopt modes such as beam balance, but the mechanical balance of using usually all is fixed now, rely on plus-minus balance weight or adjustment balance weight and centre of gyration distance to adjust balance, the effort of both having taken a lot of work exists the carry moment of torsion to cause problems such as " low load with strong power " greatly again, influences the further raising of economic benefit.
Summary of the invention:
The object of the present invention is to provide a kind of can the convenience to adjust the adjustable variable moment type slide beam balance method for oil pumping unit that the oil pumper mechanical balance also can be saved steel, electric energy spry and lightly.
The technical solution used in the present invention is as follows: set up a walking beam variable torque balance adjusting device on the oil pumper walking beam, in the oil pumper course of work, change the distance of the heavy iron phase of adjustment by this device, realize adjustable variable-pitch beam balance of oil pumper and high efficiency smooth work the walking beam axis.In said process, balance weight iron is apart from the walking beam axis recently when (being that rod string is in the down stroke original position), for extension is taken out (carry) moment of torsion, counter balance torque minimum; When balance weight iron was transferred to apart from walking beam axis highest distance position (being that sucker rod is in the upstroke original position), the counter balance torque maximum was with the peak load of balanced oil extractor work.
Method provided by the invention is novel, and is easy to implement, and the balance adjusting device that is adopted is simple in structure, in light weight, and consumptive material is few, easy to operate, and safe and reliable, utilizes this method can reduce the pumpingh well cost of production, obtains good economic benefit.
A kind of oil pumper walking beam variable moment type slide balance adjusting device general structure schematic diagram that description of drawings: Fig. 1 adopts for the present invention.Among the figure, label " 11 " is the oil pumper walking beam, and " 12 " are the oil pumping machine crank linkage.Fig. 2, Fig. 3, Fig. 4 are respectively three kinds of working state schematic representations of walking beam bending moment adjusting device in the oil pumper course of work.
The specific embodiment: enforcement of the present invention is illustrated below in conjunction with accompanying drawing.
As shown in the figure, the walking beam variable torque balance adjusting device that the present invention adopts is made up of motor 5, reducer 4, leading screw 2, bearing spider 1, expansion coupling 6, hold-down nut 3, bearing 7, connecting rod 8, fork 9, balance weight iron 10, its structure, assembled relation are as follows: leading screw 2 one ends are fixed on the bearing support 1 with nut, bearing support 1 is fixed together with expansion coupling 6 one ends, the other end is connected in series mutually with reducer 4 and motor 5, is fixedlyed connected with walking beam 11 by hold-down nut 3 in the middle part; Expansion coupling 6 other ends and fork 9 are hinged, and fork 9 upper and lower ends are hinged with connecting rod 8 and balance weight iron 10 respectively, and the bearing 7 of connecting rod 8 other ends and walking beam 11 afterbodys is hinged.Figure 2 shows that the duty of this balance adjusting device when the oil pumper extension is taken out (carry), this moment, balance weight iron was nearest apart from the walking beam axis, the counter balance torque minimum, the duty of this balance adjusting device when Fig. 4 for the oil pumper upstroke is initial is the load maximum, balance weight iron is apart from the walking beam axis farthest at this moment.Fig. 3 then is the duty between Fig. 2, Fig. 4.The said adjustable variable moment type slide beam balance method for oil pumping unit of the present invention, above-mentioned except that adopting by the balance adjusting device of leading screw screw-drive mechanism, also can adopt the adjusting device of other structures such as rack-and-pinion, fluid cylinder, its final purpose is identical with effect, all is to change the heavy iron phase of adjustment the distance of walking beam axis is realized the adjustable variable-pitch beam balance of oil pumper.
