Heat-resistant antifriction carbon plastics for pumps sliding bearings of ship energy stations, thermal and nuclear power plants

Abstract

The paper summarizes experience of development and application of high speed sliding bearings for centrifugal pumps of ship energy units, thermal electric stations, nuclear power plants. Sliding bearings work with overheated water at temperatures 200° Сand sliding velocities 20–40 m/s. Unlike metals, these sliding bearings don’t need additional oil lubrication. Two antifriction carbon plastics, namely phenolic type FUT-B and new one polyphenylene sulfide type UPFS are discussed.
