Description
Affiliated technical field
The present invention relates to a kind of linear motor oil pumping machine, be mainly used in oil field sucker-rod pumping technical field.
Background technique
The employing linear electric motor are that the pumping unit of power is compared with traditional beam pumping unit, and advantage is a lot.Linear electric motor to-and-fro motion mode meets the motion mode of oil well pump needs, and essential transformation through motion mode when having overcome electric rotating machine and driving promptly overcome motor rotation mode outputting power, essentially pass through switching mechanism and change straight line motion into.Linear motor oil pumping machine can reduce power consumption, and saves the pumping unit manufacture cost.Therefore the patent application of linear motor oil pumping machine is a lot.As Chinese patent 96217638.9, Chinese patent 99256966.4 and Chinese patent 01204055.X, all relate to the patent application of linear motor oil pumping machine.These linear motor oil pumping machines generally are made up of rope hanger, wire rope, sheave block, support, electric mover, motor stator and Equilibrator.Linear motor stator electric is fixed on the support inboard, and electric mover is installed in the middle of the motor stator.Propping up top of the trellis has sheave block, and wire rope connects rope hanger and electric mover by sheave block.Equilibrator directly is connected the linear motor rotor lower end, and linear motor rotor and Equilibrator are installed in the same side of support.Chinese patent 99256966.4 is exactly this structure that adopts.Though, in Shen Qing the patent, improving to some extent on the balance mode or on the sheave block position afterwards, all not outstanding the variation do not have material alterations.The patented technology scheme of being applied for, useful effect is not fairly obvious.Topmost shortcoming is on the structure that these linear motor oil pumping machines exist: linear motor stator electric is fixed on the support inboard, and electric mover is installed in the middle of the motor stator.The conventional construction that this is for a long time to be adopted, this structure is continued to use now always.This structure outermost surface is a support, the inboard fixedly linear motor stator electric of support, and mover is in the middle of stator.During linear electric motor work, produce a large amount of heats.Heat can not finely distribute between two stators, assembles in linear electric motor, and after linear electric motor work a period of time, temperature rises, and working efficiency descends, and consumes a large amount of electric energy.In addition, analyze from the force structure of support, the huge pulling force of sucker rod makes support produce the curved incline distortion.Be reinforcing bracket, can only adopt relatively large number shaped steel welding support, increase the support resistance to flexure.Cause increasing weight support frame, consume great deal of steel.These stators are fixed on the linear motor oil pumping machine of support inboard, maximum shortcoming is: owing to constitute the permanent magnet or the electric motor primary of motor stator, with support be same carrier, it is big that gap between deformation of timbering rear motor mover and the stator becomes, sometimes cause permanent magnet to come off, electric efficiency is greatly reduced.
Summary of the invention
The objective of the invention is:, reduce the shortcoming of electric efficiency in order to overcome the unreasonable structure that the linear motor oil pumping machine permanent magnet is fixed on the support inboard; The heat that produces when overcoming machine operation can not finely distribute, and motor heats up, and working efficiency descends, the problem that consumes a large amount of electric energy; Overcome the shortcoming that deformation of timbering rear motor air gap changes.The invention provides a kind of linear motor oil pumping machine of built-in stator.The linear motor oil pumping machine of this built-in stator can not only improve the support force situation, and the heat that linear electric motor when work produced distributed well, guarantees that the machine operation temperature is normal.
The technical solution adopted for the present invention to solve the technical problems is: the linear motor oil pumping machine of built-in stator is made up of rope hanger, flexible linking device, sheave block, support, electric mover, motor stator and Equilibrator.Propping up top of the trellis has sheave block, and flexible linking device connects rope hanger and electric mover by sheave block.Another group flexible linking device connects Equilibrator.Described flexible linking device comprises wire rope, band rope, line belt, chain etc.It is characterized in that: erect in the support and be fixed with mainboard, mainboard thickness is between the 15-45 millimeter, and width is between the 300-1300 millimeter, and height is between the 5000-12000 millimeter.Linear motor stator electric is fixed on the mainboard bi-side, and stator is a permanent magnet.Electric mover is in the motor stator outside.Be fixed with guide rail along the mainboard setting, rail length is between the 5000-12000 millimeter.The effect of guide rail is: the restriction electric mover can only move up and down along guide rail, produces shift phenomenon when preventing the electric mover motion, produces friction with mainboard.Be fixed with guiding wheel seat and upper saw pulley on the mover, have the leading screw of connection to connect between two movers, connecting on the leading screw has Regulation spring, and fixes with nut.
In order to make full use of the counter-bending ability of mainboard, mainboard is erect the direction of installing and is in support: mainboard side is to the direction of well head and rope hanger.
Equilibrator can adopt flexible linking device to be connected the linear motor rotor lower end, also can be fixed on the periphery of electric mover.
Beneficial effect of the present invention really is, overcome existing linear motor oil pumping machine stator outside, and stator is in interior unreasonable structure, and the heat that produces during machine operation can not distribute, the shortcoming that working efficiency descends; In addition, having reduced the strong magnetic field power that mainboard bears lotus and motor again is influence to mainboard.By facts have proved, the pumping unit by the present invention program makes has also obtained beyond thought benefit.The permanent magnet that the mainboard both sides are fixing, the magnetic loop of motor is reasonable, makes two row's permanent magnets improve magnetic about 10%, effectively for mover provides kinetic energy, increases mover thrust, saving power.The mainboard that posts permanent magnet does not in addition bear the load that support should bear, and deformation does not take place permanent magnet, and motor gas-gap can not change, and electric efficiency greatly improves.
