Dynamic Adjusting Mechanism of Counterbalance in Beam-Pumping Unit and its Kinetic Analysis

Abstract:

The purpose of conventional counterbalance mechanism featuring a fixed counterbalance torque is to balance the nonuniformity of polished rod load. Therefore, it cannot satisfy the demand of polish rod load which changes with well-condition and then leads to increase of power cost for decreasing quality of balance. This paper presents a new dynamic adjusting mechanism of counterbalance in beam-pumping unit that can adjust the counterbalance torque automatically without stopping the unit according to the new balance parameters derived by analyzing the variation of well-condition and increase productivity at the same time. A data comparison based on the corresponding kinetic model of transmission mechanism is also discussed.
