Design of API Series Pumping Unit
Model：RM912D-427-144
Student: lijingjing ，The College of Mechanical Engineering
Supervisor: Guo dengming，The College of Mechanical Engineering
【Abstract】The pumping units are one of important parts in exploitation equipments。Driving by the pumping units, the other equipments are running in order to achieve the mechanized exploitation of the oil well 。The unusual sharp beam-pumping unit is developed from the conventional beam-pumping units by the modification of crank and the optimization of size。 In this article, working routine and power-saving technology of the unusual sharp beam-pumping units will be introduced and the designing procedure, First，serial geometric calculation movement calculation and dynamic calculation of 4-bar rod of pump unit were finished accord to known design data and design standard to express law of motion of this kind of equipment。Second，process parameter was computed intensity of essential parts was checked and the selection of correlating equipments, such as electro-motor and reducing gearbox, sum up the characteristic in the performance. The end, working condition was analyzed and sketch was designed。In the middle of produce ,Excel was used to edit computational program。
