This standard applies to the installation and adjustment of thrust bearings and guide bearings of vertical hydroelectric generator sets. The installation and adjustment of reversible hydro-turbine generator sets, horizontal hydro-turbine generator sets, water pump motors, and bearings with atypical structures that have specific technical requirements from the manufacturer can be implemented as a reference. This standard is the technical measure for bearing installation and adjustment in the "Technical Specifications for the Installation of Hydrogenerator Sets" (GB/T 8564). The quality standards for bearing installation should be based on the design drawings and the requirements of GB/T 8564. This standard is formulated based on the process measures usually adopted when installing and adjusting bearings with typical structures. In the case of changes in the bearing structure, some of the process measures specified in this standard can be changed.
