The equipment has a good balance as well as energy saving features,what is more, maintaining many advantages for conventional beam pumping unit,such as simple structure, reliability, operation conventional，and conventional maintenance during the maximum level，it is appropriate in all kinds of status of oil exploration, being a Comprehensive relatively good performance of pumping. The article on the basis of the basic theory in the beam pumping unit takes the following calculation: the stroke-selection and calculation for beam pumping unit, horse head hanging load calculation, the Calculation for the maximum output shaft torque of the reducer the calculation for the electrical power and so on. Finally, present the size calculation to various parts and verification. The beam pumping unit improves the effectionof the crank balance beam balance or pure walking beam by making the bending beam balance and the rotating crank stack so that reaches energy-saving purposes by reducing the fluctuations in power output , helping to improve the fore of the members, reducing the occurrence of accidents in pumping , improving the overall efficiency of pumping units. it is satisfied to the performance by the analysis and the optimization for the balancing equipmen
