A Computational Method for Planar Kinematic Analysis of Beam Pumping Units

Journal of Energy Resources Technology, 2007
A generalized computational method for planar kinematic analysis of pumping units is presented in this study. In this method, a local coordinate system is assigned to each body with respect to a fixed global coordinate system. The position of each point in a body is determined by specifying the global translational coordinates of the local coordinate ...

Study of power balance technology on beam pumping unit

Proceedings of 2013 2nd International Conference on Measurement, Information and Control, 2013
Against the balance of beam pumping unit, power technology balance on beam pumping unit is proposed on the basis of kinetic analysis. The balance technology uses RMS minimum power, instead of RMS torque minimum. Oil pumping motor power curve which is satisfied Dirichlet conditions is expanded into convergent trigonometric series.
