联动抽油机组是将多台抽油机用一根动力轴连接而成的一种用于丛式井抽油的新型采油装置。这种机组由驱动电动机、胶带轮、支架轴、离合器、万向轴、传动链、游梁式抽油机、测试仪、显示报警装置和计算机等组成。由于采取了联动，下冲程时抽油杆柱及抽油机杆件所积蓄的势能都传到动力轴带动各台抽油机运行，使扭矩曲线水平轴以下的负值得以消除，即在下冲程时形成的无用功全部转换成动力做功。运行试验证实，联动抽油机组载荷波动小，运行平稳，输电线路损耗低，有功节电率约43%，综合节电率约72%。
The linkage pumping unit is a new type of oil recovery unit for pumping oil in a cluster well, which is formed by connecting multiple pumping units with a power shaft. This unit consists of a drive motor, tape pulley, bracket shaft, clutch, cardan shaft, transmission chain, beam pumping unit, tester, display alarm and computer components. As a result of the linkage, the potential energy accumulated by the sucker rod rod and the rod member of the sucker rod during the down stroke is transmitted to the power shaft to drive each pumping unit to run, so that the negative value below the horizontal axis of the torque curve can be eliminated, that is, during the downstroke When the formation of the useless all converted into power work. Operation test confirmed that the linkage pumping unit load fluctuations, smooth operation, transmission line loss is low, the active saving rate of about 43%, the overall saving rate of about 72%.
