液压式抽油机的设计 摘要：本文根据液压抽油机的基本参数和机构性能特点，以常规游梁式抽油机为基础模型，对其进行技术性改进，而得到具有新型节能特点的液压式式抽油机。该机具有无极调节冲程长度、冲次，悬点震动载荷小，控制灵活、方便等优点，可以适应不同的油井状态，同时在最大限度内保持了常规游梁式抽油机结构简单、操作、维修方便的优势，适合在各种工况的原油开采，是一种综合性能比较好的液压抽油机。文章在液压式抽油机基本理论的基础上，做了以下计算：液压式抽油机驴头悬点载荷的计算、液压系统原理图的设计、液压缸的设计和电动机的功率计算等。最后介绍的是各零部件设计的尺寸计算与校核，液压式抽油机通过液压系统驱动抽油杆上下往复运动；平衡系统主要用于控制和调节工作行程换向和抽油杆柱运动的平衡，是电机的负载均匀，达到节省能源的目的。，并且有利于改善构件的受力状况，减少抽油机事故的发生，从而提高抽油机的综合效益。对平衡的配置进行分析和优化设计，满足所要求的工况需要。 关键词：液压抽油机； 液压系统； 液压缸 The design of hydraulic pumping unit  Abstract: According to the basic parameters of hydraulic pumping units and agencies of the performance characteristics of a conventional beam pumping unit for the base model, its technical improvements, and get a new energy-saving features of the hydraulic pumping unit. The machine has limitless adjustment stroke length, stroke, shock suspension point load of small, flexible control and easy, well you can adapt to different states, while the maximum extent possible to maintain the conventional beam pumping unit of simple structure, operation, the advantages of easy maintenance, suitable for a variety of working conditions in crude oil production, is a relatively good overall performance hydraulic pumping unit. Article in the hydraulic pumping unit based on the basic theory, do the following calculation: the first ass hydraulic pumping rod load calculations, schematic design of the hydraulic system, hydraulic cylinder design and motor power calculation. Finally, the design is the size of the parts calculation and check, hydraulic pumping unit driven by the hydraulic system of the upper and lower reciprocating rod; balance system is mainly used to control and adjust the work schedule for movement to and sucker rod balance the electrical load evenly, to save energy purposes. And components will help to improve the situation by force, to reduce the occurrence of pumping units, thereby improving the overall efficiency of pumping units. The configuration of the balanced analysis and optimal desig
