发布时间：2018-10-25 14:01
【摘要】：本文根据工程实践所调研的参数,结合实际生产环境及加工工艺性,首先提出了捞油抽子总体设计方案。其次对各部分机构有针对性的加以研究,通过ANSYS有限元中静态结构力学与强度理论中屈服准则相结合的方法仿真校核了捞油抽子柱塞杆等核心构件。在此基础上,基于机械振动力学相关知识建立了捞油抽子的有阻尼两自由度线性系统强迫振动力学模型,通过模态分析方法求解捞油抽子的固有频率、振型,以此确定捞油抽子正常工作时是否存在共振现象发生。对捞油抽子漏失量及密封橡胶筒所受摩擦力问题主要是以连续介质力学为理论基础,具体落实到前面两个问题分别以流体力学粘性流体流动、弹性力学作为工具,同时结合工况适当提出假设、建立相关模型最终通过试验数据验证。另一方面,研究内容是联接机构在制动、启动中所受动载荷与静载荷之间的函数关系,通过能量守恒与材料力学知识相结合推导出两类冲击模型。最后,本文系统的对捞油抽子力学性能进了分析,阐述了所研究内容对原油生产、设备正常运行的意义。
[Abstract]:In this paper, according to the parameters investigated in engineering practice, combined with the actual production environment and processing technology, the overall design scheme of oil recovery pump is put forward. Secondly, through the research of each part of the mechanism, the method of combining static structural mechanics with yield criterion of strength theory in ANSYS finite element method is used to verify the core components such as the plunger rod. On this basis, based on the knowledge of mechanical vibration mechanics, a dynamic model of forced vibration of a two-degree-of-freedom linear system with damping is established, and the natural frequency and mode shape of the oil pump are solved by modal analysis method. In order to determine whether there is resonance phenomenon in the normal operation of the oil recovery pump. For the leakage of oil extractor and the friction of sealed rubber cylinder, the theoretical basis is mainly continuum mechanics, and the first two problems are carried out with fluid viscous fluid flow and elastic mechanics as tools, respectively. At the same time, the hypothesis is put forward according to the working condition, and the relevant model is finally verified by the test data. On the other hand, the research content is the functional relationship between the dynamic load and the static load in the braking and starting of the coupling mechanism. Through the combination of energy conservation and the knowledge of material mechanics, two kinds of impact models are derived. Finally, the mechanical properties of the oil pump are systematically analyzed, and the significance of the research content to the crude oil production and the normal operation of the equipment is expounded.
