一、前言在油田中,原油是用活塞式抽吸泵从油井的底下抽到地面上的。这种抽吸泵的结构和液压缸相似。抽吸泵活塞摩擦力的测定对研究各类密封圈的结构、尺寸、材料以及研究活塞运动速度、工作压力、油液粘度对摩擦力的影响是极为重要的,而这项工作目前在国内外尚不多见。利用计算机对液压缸的摩擦力特性进行测试,数据的采集和处理容易,在屏幕上可用图形显示各参数的变化曲线,并可通过打印机及绘图仪输出测试结果。本文对三种密封材料的摩擦力在177个不同温度和压差工况下进行了测试,提供了一些可供参考的结果。二、液压缸摩擦力的测试 1、测试目的及条件为了模拟抽吸泵在油井不同深度处的工
I. INTRODUCTION In oil fields, crude oil is pumped from the bottom of the well to the ground by a piston-type suction pump. The structure of this suction pump is similar to a hydraulic cylinder. Determination of suction pump piston friction For the study of various types of seal ring structure, size, material and research piston velocity, working pressure, viscosity of the oil on the friction force is extremely important, and this work is currently at home and abroad Not yet seen. The use of computer to test the frictional characteristics of the hydraulic cylinder, the data collection and processing easy, available on the screen graph shows the curve of the various parameters, and through the printer and plotter output test results. In this paper, the friction of the three sealing materials tested in 177 different temperature and pressure conditions, provides some reference for the results. Second, the hydraulic cylinder friction test 1, the purpose and conditions of the test In order to simulate the suction pump at different depths of the wells
