摘要 Abstract Conwentional beam-pumping unit to take out the oil machine,publishing in the machine oil extraction equapments at the earliest stage,applied extensive,the most simple equipments in structure.Pumping unit is an important component in the petroleum industry, driving by the pumping units，and the other equipments are running in order to achieve the mechanized exploitation of the oil well. It is mainly classified beam and non- beam two categories. Beam style pumping unit mainly consists of the engine, triangle belt, crank, connecting rod, beam, beam, donkey head, hanging a rope device, cradles, pry block, brake system and balance weight. With the development of the ages, the requirements of energy-saving and the consciousness of environmental protection enhancement, on the basis of the combining of the theory and practice, the current domestic and international pumping unit’s overall development trend is toward super-load, long stroke, low stroke times, precise balance, automatic, intelligent, energy- saving, high adaptability and non-beam long stroke direction. This design was mainly according to the principle of four-pole framework (crank -- connecting rod -- beam -- beam) of pumping unit’s. In this article ,working routine and power-saving technology of the conventional beam-pumping unit will be introduced, and during the designing procedure, the analysis of kinetic and dynamic to the pumping units express law of motion of this kind of equipment .The air load of beam style pumping unit is one of the important parameters, which is the first sign of the work capacity, and see it whether energy-saving, the technical indicators are the size of the electromotor consumption power and the work state of the decelerator.Completely this design said the difference al mutually a development general situation that took out the oil machine excellent to turn the design and it economized on energy the principle .Moreover,designed to takin
