Kinematic Analysis of Long Stroke Pumping Unit with Post Pulley
In view of the shortcomings of high peak of crank torque and polished rod load,short stroke and serious wear of steel wire rope,the structural characteristics of the conventional beam pumping unit are analyzed. On the basis of that,the post pulley mechanism that change with the displacement of the s...
