Dynamic Behavior Modeling and Working Performance Analysis of Double Horsehead Pumping Unit

摘要

Double horsehead pumping unit is widely used because of its good balance effect, low net torque peak and low energy consumption. Through the system dynamics modeling of the structure of the double horsehead pumping unit, this paper decomposes the suspended point load into rod and liquid column static load, inertial load, vibration load and friction load, etc. and performs programming calculations. Pumping speed of the stroke and the point of suspension velocity, acceleration, load and net torque gearbox impact were analyzed. The results show that the dynamic model of the double horsehead pumping unit in this paper has high calculation accuracy, which provides necessary theoretical support for the application of pumping unit well system dynamics engineering.
