Description
Technical field
The utility model relates to a kind of small diameter long plunger processing unit (plant), belongs to technical field of oil production engineering.
Background technology
Oil pumper sucker rod pumping is artificial lift oil production method, simple with its equipment, small investment, and convenient management, the advantages such as strong adaptability are extensively adopted by domestic and international each main oilfield.Oil well pump is the down-hole key equipment of sucker rod pumping system, is arranged on the bottom of tubing string, is submerged in well liquid, by swabbing action, oil is discharged to ground.Oil well pump is mainly made up of pump barrel, plunger, standing valve and travelling valve.Pump barrel is cylinder sleeve, and the plunger with travelling valve is housed in it.Plunger and pump barrel form sealing, for discharging liquid from pump barrel.
In recent years, due to the exploitation of Oil in Super-low Permeability Reservoir Size, be subject to the impact of formation condition, well yield is low, and for all larger Φ 38mm, Φ 44mm of the general discharge capacity of oil well pump of low production capacity oil well, cause oil well for adopting imbalance, therefore the efficiency of oil well pump is low, cause the system effectiveness of sucker-rod pumping system very low, energy consumption is very large.Researched and developed on this basis Ф 25mm small diameter long plunger oil-well pump, more thin longer workpiece processing, processes its difficulty of processing for lathe larger.Due to the diameter of plunger is dropped to 25mm by 32mm or 38mm, the reducing of diameter of plunger, while causing turning, the amount of deflection of long-plunger increases, thereby causes the workpiece deformation after processing to increase, and difficulty of processing increases, and machining accuracy cannot guarantee.
Summary of the invention
In order to overcome the deficiencies in the prior art, the utility model provides a kind of small diameter long plunger processing unit (plant).
A kind of small diameter long plunger processing unit (plant), comprises centralizer body mechanism, and the anti-directive wheel that quivers, moves towards track, track underframe, glide base, tailstock, electric system.Centralizer body mechanism is mainly made up of wiper block, guide pad, limited block and joint; The anti-directive wheel that quivers is mainly made up of directive wheel, deep groove ball bearing, journal stirrup, walking sliding sleeve; Moving towards track is mainly made up of carrier unit, intermediate orbit, bolt and pad; Glide base is mainly made up of slide block, adjusting support, bearing, bearing bracket stand; Electric system is mainly by AC-AC servomotor, belt pulley and composition of the control system.
A process for small diameter long plunger processing unit (plant), contains following steps;
Wiper block mechanism is arranged on track underframe, be positioned at the anti-directive wheel front end that quivers, can move between directive wheel at track support and anti-quivering along track, small diameter long plunger is through wiper block and guide pad, in the process of advancing at long-plunger, play the effect of righting and guiding, assurance small diameter long plunger is advanced steadily efficient.
The anti-directive wheel that quivers is fixed on track underframe, walking sliding sleeve is with the form of matched in clearance, be enclosed within and move towards on track, two journal stirrups are fixed on walking sliding sleeve in the mode of welding, the top of journal stirrup is installed respectively and is coordinated two deep groove ball bearings, the mode axis that deep groove ball bearing is installed is parallel with the axis that moves towards track, on space with to move towards track vertical.The anti-directive wheel that quivers is mainly made up of 6 directive wheels, and every two is 1 group, totally 3 groups, can regulate spacing between directive wheel.The outer surface of directive wheel contacts with long-plunger, and long-plunger is played a supporting role, and retains certain gap, guarantees long-plunger advance of freedom in rounding process, prevents bending and vibration, even if workpiece has slight deformation or swing, guarantees small diameter long plunger linearity.
Glide base is positioned at and moves towards on track, can be along moving towards moving before and after track.Glide base is mainly used to the elongated or yielding long-plunger workpiece of fixed clamp, and drives long-plunger uniform motion in orbit, and movement velocity is by electric system control.On glide base, there is upper and lower automatic regulation function, can make long-plunger be positioned at same level in rounding process, guarantee small diameter long plunger concentricity.
Electric system is for controlling direct of travel and the speed of glide base, and brake hard.Dynamic design has been selected AC servo motor, and power bracket is large, and the highest velocity of rotation is low, and along with the increase of output power fast reducing, can low speed steadily efficient operation, guarantee that long-plunger is in rounding process, each size can be ground to and grind the identical time.
The utility model has the advantages that:
1, realized the processing of Ф 25mm small diameter long plunger.At long-plunger, in rounding process progradation, the effect of righting and guiding is played by wiper block mechanism, and the anti-directive wheel that quivers prevents bending and vibration, even if workpiece has slight deformation or swing, guarantees small diameter long plunger linearity.
2, can meet the processing of different length Ф 25mm small plunger diameter, in order to increase the wearability in its surperficial fineness and long-term use, surperficial Ke Du Chrome or nickel phosphor plating.In the hope of reaching higher, wearability and fineness.
3, realized the steady highly-efficient processing of Ф 25mm small diameter long plunger low speed, electric system is selected AC servo motor, guarantees that long-plunger is in rounding process, and each size can be ground to and grind the identical time.
