For the quantification of energy consumption loss during transmission and conversion in beam unit production system, the correlation detection technology and corresponding hardware and software structures have been used to detect the real-time synchronous data ,such as polished rod load, displacement, motor torque and angular speed ,s6 synchronous detection for the surface mechanical efficiency of beam units was achieved, and the energy loss in leather belt, in decelerator, in four links was expressed. Through field tests, effect evaluation and data analysis to the synchronous detection installations, and the relevant theories were confirmed. The influence of motor＇s drive efficiency to the pumping unit＇s surface efficiency and the stored energy change of balance weight in the operation were expressed .For correct type selection of oil pumping unit, better energy-saving effects and lower production costs in different developmental stages, the detection means and methods have been provided.
