Description
Technical field
The utility model relates to a kind of oil field machinery oil oil pumper, is applicable to that particularly the external rotor electric of oilfield oil well drives oil pumper.
Background technology
There is certain limitation in conventional beam-pumping unit, and energy consumption is big, and stroke, jig frequency can't dynamic adjustments; There is the sealing situation of difficult in reducer.At present, domestic-developed goes out the oil pumper that linear electric motors drive, and is the oil pumper of the linear electric motors driving of 01204055.X as the patent No., is a kind of electric mover straight reciprocating motion that utilizes, and drives wire rope and oil pumping polish rod, finishes the oil pumping task.Solved long stroke, the adjustable problem of jig frequency.Some oil field oil recovery block needs the energy-saving pumping unit of long stroke, low jig frequency.Conventional pumping unit can not meet the demands, and we have researched and developed external rotor electric and have driven oil pumper based on above-mentioned situation.
Technology contents
The purpose of this utility model provides a kind of external rotor electric and drives oil pumper, finishes well recovery, and can regulate oil pumping jig frequency and stroke arbitrarily according to oil well reality; Improve the parts force-bearing situation, improve the oil recovery effect.
The structure that external rotor electric drives oil pumper is: drive reducer, support, counter weight device, wire rope, polished rod eye, electrical control cabinet and base by electricity and form.Be fixed with the shaft holder that electricity drives reducer at the top of support, be fixed with electricity on the shaft holder and drive reducer.Motor and reducer appearance that this electricity drives reducer are one.During work, the axle that electricity drives reducer does not change, its outer rotor rotation, and this working method with general motor is different.Wire rope is wrapped in electricity in an orderly manner and drives on the reducer shell.Wire rope one end connects polished rod eye, and polished rod eye connects oil pumping polish rod.The wire rope other end connects counter weight device.Be fixed with the brake gear that electricity drives reducer at a top of the trellis.Base is arranged at the bottom at support.
Support can be removed well head and makes things convenient for workover treatment during for well workover, between support and the base roller is arranged.Standoff mobile device on base.Mobile device can adopt hydraulic shifter unit, also can adopt the screw rod mobile device.
It is to mix stepping single flow electricity to drive reducer that electricity drives reducer.
Keep stable when counter weight device is moved up and down, in track is arranged, the counter weight device shell has movable pulley.When counter weight device moves up and down, the movable pulley orbital motion on the shell.
In order to make brake torque big, safe and reliable, brake gear adopts electromagnetism main brake and mechanical type auxiliary brake two cover brake gears.
External rotor electric drives oil pumper and back and forth rotates by the electricity driving reducer shell that props up top of the trellis, directly drives wire rope and oil pumping polish rod straight reciprocating motion, thereby finishes oil machinery oil pumping work.When the oil pumping polish rod upstroke, counter weight device drives reducer to the polished rod acting with electricity, and the Based Intelligent Control cabinet drives reducer to electricity and quickens adjustment simultaneously, finishes the oil recovery pumping.During the oil pumping polish rod down stroke, electricity drive reducer with polished rod to the counter weight device acting, the Based Intelligent Control cabinet drives the reducer adjustment of slowing down to electricity simultaneously, finishes the return of oil pump plunger piston.Drive technology by novel electricity, electricity is driven reducer carry out dynamic speed adjustment, realize fast slow pumping work down on the oil pumper.This is just meeting the load change of rod-pumped well, can also improve the stressed situation of sucker rod simultaneously.Electricity drives reducer and adopts novel electricity to drive control technology, can carry out step-less adjustment and the up-down stroke time is reasonably mated the oil pumper jig frequency.
Its power drive system characteristics are: electricity drives the reducer outputting rotary power,, drives polished rod and does reciprocating linear motion to polished rod eye by wire rope transfers, can reach step-less adjustment oil pumper jig frequency.Can drive reducer to electricity and carry out soft start, starting current reduces significantly, avoids oil pumper is produced excessive mechanical shock, prolongs service life of equipment.The mode that the brake gear of this machine adopts the electromagnetism main brake to combine with the mechanical type auxiliary brake, brake torque is big, and is safe and reliable.Also have simple in structure, reliable operation in addition, energy-saving effect is preferably arranged.
