The paper investigates the lubrication performances of water film under the consideration of different lubrication models in the primary circuit loop system of nuclear power plant. Variations between lubrication performances and rotating speeds, eccentricity ratios and lubrication models are obtained. Research results show that rotating speeds and lubrication models have significant influences on the lubrication performances. There exist optimum eccentricity ratios at which the bearing load carrying capacity and friction characteristics can strike the balance point. Research conclusions have guiding significances on the structure designs and optimization for such bearings in the primary circuit loop system. (C) 2020 Elsevier Ltd. All rights reserved.
