Abstract
The utility model relates to an oil pumping unit, and particularly a double-chain oil pumping unit with long stroke and high load. The double-chain oil pumping unit comprises an upper cover, a reversing head sheave, a steel wire rope, a balancing weight, a base seat, a belt pulley, an outer shell, an electronic control cabinet, a reduction gearbox, a staircase, a platform frame, two chains, a reversing frame, a chain rail, an oil pumping rod, a chain wheel, an electromotor, and a belt. The outer shell is installed on the base seat. The platform frame is arranged on the outer shell. The reversing head sheave is placed in the upper cover. The steel wire rope is wound at one end on the reversing head sheave to be connected with the balancing weight, and the other end of the reversing head sheave is connected with the reversing frame. The oil pumping rod is connected with the reversing frame. A transmission shaft of the electromotor is connected with the belt pulley. The belt pulley is connected with a torque output portion of the reduction gearbox through the belt and a torque output portion of the reduction gearbox is connected with the chain wheel. The chain wheel is meshed with the chains. The chains are connected with the reversing frame. The double-chain oil pumping unit is long in stroke, and high in oil pumping efficiency. Due to the fact that the steel wire rope is used as a flexible connecting piece, the windward area can be reduced, and accordingly swing amplitude of the pumping rod is reduced, and certain advantages are obtained.
Description
Technical field
The utility model relates to a kind of oil pumper, particularly a kind of double chain type oil pumper of long stroke high load capacity.
Background technology
At present, the oil pumper majority that oil field at home adopts is beam pumping unit, and this oil pumper is subject 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 solidifying oil, hyposmosis etc.) mining phase, the oil field average moisture contents such as triumph, the Liaohe River, North China, Central Plains are more than 80%, deeply take out in the urgent need to both being applicable to, be applicable to again thickened oil recovery, the energy-saving type oil pumper of large load, long stroke.
The utility model content
The utility model is intended to address the above problem, a kind of double chain type oil pumper is provided, its stroke is long, reduced the relative deformation value of oil pumper, improved coefficient of fullness and the discharge coefficient of oil well pump, pumping efficiency is high, more energy-conservation, use wire rope as flexible connecting member, can reduce front face area, thereby reduce the sucker rod amplitude of fluctuation, its technical scheme that adopts is as follows:
a kind of double chain type oil pumper, comprise: upper cover, the commutation head sheave, wire rope, 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 base, described paralell is located on shell, described staircase is located on shell and between paralell and base, described upper cover is installed on cover top portion, described commutation head sheave is arranged in upper cover, described wirerope-winding one end on the commutation head sheave is 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 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 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 simultaneously output.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 extend its application life.In 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 pair of chain drive, can reduce the stressed of one-sided chain, the two commutation head sheaves that adopt in addition also can make counterweight amplify 3 times to the pulling force of reversing gear bracket, so this oil pumper can bear larger load.Use wire rope as flexible connecting member in design, can reduce front face area, thereby reduce the sucker rod amplitude of fluctuation.
