摘要
推力轴承作为高温潜油电泵的主要承载部件,对于其运行起着至关重要的作用。基于FLUENT流体分析软件,建立了推力轴承油膜润滑模型,主要分析不同瓦张角、油膜厚度以及周向倾角条件下推力轴承的承载能力。研究结果显示,随着瓦张角的增加,推力轴承的总承载力呈现先增加后减小的趋势;随着油膜厚度的增加,推力轴承的承载能力逐步减小,最终趋于平缓;随着周向倾角的增加,推力轴承的承载能力先增加后趋于平缓。通过建立油膜与推力轴承的流固耦合模型,分析推力轴承在运行过程中的受力及其变形。
As the main load-bearing part of high-temperature electric submersible pump,thrust bearing plays an important role in the operation process.Based on the FLUENT fluid analysis software,the oil film lubrication model of thrust bearing is established,which mainly analyzes the bearing capacity of thrust bearing under the conditions of different pad opening angle,oil film thickness and circumferential inclination angle.The results show that the total bearing capacity of thrust bearing increases firstly and then decreases with the increase of the pad angle;with the increase of the oil film thickness,the bearing capacity of thrust bearing decreases gradually,and finally tends to be gently;As the increase of the circumferential angle,the bearing capacity of thrust bearing increases firstly,and then tends to be gently.Based on the fluid structure coupling model of oil film and thrust bearing,the force and deformation of thrust bearing are analyzed during operation.
