The reasons for the temperature rise of fire pump bearings
Aug 11, 2020· The primary reasons for the temperature rise of fire pump bearings are: (1) The tortuosity or absence of the pump shaft will cause the pump to oscillate and cause heating or wear of the bearing. Due to the axial thrust of (2) (for example, when the balance plate and the balance ring in the water pump are severely damaged), the axial load of the bearing increases, causing the bearing to
