Finite Element Analysis of Thrust Bearing in ESPCP System

Thrust bearing is one of the most important components in ESPCP system, which determines the life of the whole system under the restriction of some factors such as the installation depth and the viscosity of swabbed petroleum oil etc. To increase the ability of high temperature resistance of thrust bearings under the limited radial size, the damage reason of applied bearings was analyzed. Some different modified methods were employed on configuration and material. Contact problems were researched with finite element analysis software. Comparison of the analysis results shows that in the tube, it is optimum that 8 rollers thrust bearings are used in 10mm radial tube without holders.
