Description

The direct driving motor oil pumper
Technical field
The utility model is a kind of novel oil production mechanical device that is used for oil recovery aspect, oil field, belongs to petroleum machinery technical research field.
Background technology
Mechanical oil recovery is oil recovery means main on the oil field; Wherein beam pumping unit recovers the oil and occupies an leading position; At present group of PetroChina Company Limited. is with 121,610 of common beam oil pumpers, and the beam pumping unit operating principle is after motor passes through the deceleration of V belt reduction box; Become rotatablely moving of reduction gearbox output shaft by quadric chain the reciprocating motion of walking beam horse head; Drive polished rod and sucker rod work rectilinear motion up and down reciprocatingly with horse head, again the plunger in the downhole pump is passed in this motion, make it the work oil pumping through sucker rod.But because beam pumping unit exists shortcomings such as structure is unreasonable, energy consumption is high, power factor is low, system's average efficiency is merely 24%, and cost for oil production is high, and energy consumption has reached 70,000,000,000 RMB; Raise the efficiency for reducing cost, various countries just improve beam pumping unit one after another and the research and development blue elephant is carrying out a series of trial, but the problem of still unresolved " low load with strong power " such as out-phase type oil pumpers of development, energy-saving effect is not remarkable; Successively developed both at home and abroad the long-stroke pumping unit without walking beam of various ways again, but these oil pumper pluses and minuses and depositing wait further research with perfect.
In addition; Along with continually developing of oil field; It is day by day complicated that the oil exploitation condition becomes, and DP technology has proposed long stroke, low jig frequency, big pump to sucker rod pumping equipment and new requirement such as taken out deeply, and beam pumping unit can not satisfy the requirement of DP technology on applicability.
Summary of the invention
In order further to improve mechanical oil recovery efficient, saves energy, mining requirement such as satisfy that particular oils Tibetan area block length stroke, low jig frequency, big pump are taken out deeply promotes the development of China's oil production equipment industry, has designed a kind of new pumping unit---the direct driving motor oil pumper.This direct driving motor oil pumper is used the design concept of simplifying, and has advantages such as simple in structure, superior performance, safety and stability, maintenance cost are low, energy-efficient, suits to promote the use of in the oil field.
The utility model is that the technical scheme that problem adopted that solution proposes is: the direct driving motor oil pumper is made up of magneto, sleeve spline shaft coupling, roller assembly, guide wheel assembly, flexible linking device, truss assembly, ballast box assembly, electric block; Magneto and roller assembly are positioned at truss assembly top; The guide wheel assembly is positioned at front side, truss assembly top; Flexible linking device is walked around the roller assembly and is connected with polished rod eye with guide wheel assembly one end, and the other end is connected with the ballast box assembly; Its principal character is: magneto is that suspension type is installed, and magneto, roller assembly, guide wheel assembly all connect fixing through bolt, and magneto directly is connected through the sleeve spline shaft coupling with the roller assembly between the two.The guide wheel assembly is made up of guide wheel assembly welding and bearing support assembly; The guide wheel assembly welding is the overall structure that axle, wheel, gusset are welded; It is inner that the ballast box assembly is positioned at the truss assembly; The center of gravity of ballast box assembly overlaps with the center of truss assembly, and electric block is fastened on truss assembly inner tip through bolt.
The beneficial effect of the utility model is to have saved reduction box and changement, and the direct driving rolls assembly of magneto carries out oil producing operation, and magneto self is realized rotating, and this invents compact overall structure, has realized long stroke; In light weight, floor space is little, and is easy to maintenance; Energy-efficient.
