Description
Technical field
The utility model relates to a kind of oil pumper, particularly a kind of double-stranded bar broadband type oil pumper of long stroke high load capacity.
Background technology
At present, the oil pumper majority of domestic Oilfield using is a beam pumping unit, and this oil pumper is subjected to the restriction of structure, and is bulky, and stroke is lower, and operating efficiency is also lower; In addition, domestic each oil field great majority enter high water-cut stage and special oil reservoir (viscous crude, high oil, hyposmosis etc. with fixed attention) mining phase, oil field average moisture contents such as triumph, the Liaohe River, North China, Central Plains are more than 80%, press for and both be applicable to deeply and take out, be applicable to thickened oil recovery again, the energy-saving type oil pumper of big load, long stroke.
Summary of the invention
The utility model is intended to address the above problem, a kind of double-stranded bar broadband type oil pumper is provided, its stroke is long, reduce the relative deformation value of oil pumper, improved the coefficient of fullness and the discharge coefficient of oil well pump, pumping efficiency height, more energy-conservation, utilization load-bearing broadband is as flexible connecting member, can improve fatigue resistance, improve application life, its technical scheme that adopts is as follows:
A kind of double-stranded bar broadband type oil pumper, comprise: loam cake, the commutation head sheave, the load-bearing broadband, balancing weight, base, belt pulley, shell, electrical control cubicles, reduction box, staircase, paralell, article two, chain, reversing gear bracket, chain track, sucker rod, sprocket wheel, motor and belt, described shell is installed on the base, described paralell is located on the shell, described staircase is located on the shell and between paralell and base, described loam cake is installed on cover top portion, described commutation head sheave is arranged in loam cake, described load-bearing broadband be wound in the commutation head sheave on the one end be connected with balancing weight, the other end is connected with reversing gear bracket; Described sucker rod is connected with reversing gear bracket, the turning cylinder of described motor is connected with belt pulley, described belt pulley is connected with the torque input part of reduction box by belt, the torque efferent of described reduction box is connected with sprocket wheel, described sprocket wheel is meshed with chain, and described chain is located in the chain track and with reversing gear bracket and is connected.
The utlity model has following advantage: adopt chain drive, the stroke of overlength is arranged, reduced the relative deformation value of oil pumper, thereby the coefficient of fullness and the discharge coefficient of oil well pump have been improved, and then improved the pumping efficiency of oil well pump, and reduce cost per unit, increased output simultaneously.This design has reduced the reciprocation cycle number of times of the required oil well pump of unit crude output, thereby has reduced the tired and wearing and tearing of rod string, has improved the condition of work of device, can prolong its application life.In the design, adopt reversing gear bracket, make the oil pumper can the long term maintenance linear uniform motion.Simultaneously, because its stroke is long, loss of plunger stroke is little relatively, thereby more energy-conservation.Adopt double-stranded bar transmission, can reduce the stressed of one-sided chain, the two commutation head sheaves that adopt in addition also can make counterweight that the pulling force of reversing gear bracket is amplified 3 times, so this oil pumper can bear bigger load.Fatigue resistance can be improved as flexible connecting member in utilization load-bearing broadband in the design, has improved application life.
