Dynamic rod pump model

On the basis of full kinematic analysis in terms of position functions and velocity analogues, a dynamic model of the drive of rod deep well pump PSHGN8-3-5500 is proposed, containing the main geometrical kinematic, inertial and power parameters. Integration of differential equations of the dynamic model is carried out under the condition that the pump is driven by the asynchronous motor 4AR180M3 U3. The influence of the number of swings per minute on the main parameters of the rod pump operation is investigated. The laws of change of angular velocity and angular acceleration of the driving crank in starting and steady-state modes are determined.
