PAGE 工业职业技术学院毕业论文 题目：螺杆泵的结构及工作原理研究 班 级： 姓 名： 专 业： 指导教师： 答辩日期： 摘要 螺杆泵又叫渐进式容积泵，由定子和转子组成，两者的螺旋状过盈配合形成连续密封的腔体，通过转子的旋转运动实现对介质的传输。它具有结构简单、流量均匀、扰动小、携带能力强等优点。在石油资源地位日益重要的今天，如何提高效率降低成本成为我们追求的主要目标，而螺杆泵的发明与使用为我们提供了一种新的有效地原油举升方式，尤其是在含砂稠油或聚驱井中成效尤为明显。 本文主要就螺杆泵采油系统的组成原理及工况诊断方面研究。系统的分析螺杆泵采油系统的工况及诊断方法，并提出需要改进的未完善之处。 关键字：螺杆泵 高效 降低成本 SCREW PUMP ABSTRACT Screw pump and that gradual displacement pump, the stator and rotor composition, both the spiral with interference to form a continuous sealed cavity body, through the rotation of the rotor motion realization of transmission of medium. It is simple in structure, flow evenly, small, strong ability to carry disturbance, etc. Oil resources in an increasingly important position today, how to improve efficiency reduce costs become our pursuit of the main goal, and the invention of the screw pump and use for we provides a new way to effectively lifting crude oil, especially in contain arenaceous heavy oil or polymer flooding the well is especially remarkable results. In this paper, the composition of the screw pump oil production system and working principle of diagnosis research. The analysis of the system of screw pump the operation condition of the oil production system and diagnosis methods, and puts forward the need to improve not perfect place.
