【Abstract】 The double donkey headed oil suction pump is formed by adding the rear donkey head on the rear arm of moving beam of conventional moving beam styled oil suction pump and by using the driving rope to replace the hard linking of connecting rod, so as to satisfy the working requirement of variable arm of force. Its kinematics and kinetics law differs from those of the general moving beam typed oil suction pump. In order to determine the suspension point of double donkey headed oil suction pump and kinematics status and law of each component, this paper established corresponding analytic equation of kinematics and kinetics analysis, and carried out calculation on the kinematics and kinetics law of the double donkey headed oil suction pump. Using the compiled corresponding computer program to define the variation law of kinematics parameter and kinetics parameter of the oil suction pump within one period, thus provided theoretical basis for reasonable motor selection, and design of mechanical changeover and balancing weight.更多还原
