The function of the Steam turbine AC lube pump  125LY-35-8  is to supply oil, lubricate, and cool the bearings of the unit. Provide stable and sufficient pressure oil for the speed control system and protection devices. The main oil pump is one of the important auxiliary components of the steam turbine, installed inside the front box of the unit, and provides all lubricating oil and security oil for the unit at full speed. During the startup and shutdown of the steam turbine, the lubricating oil and security oil of the unit are provided by the auxiliary AC lubricating oil pump and the high-pressure starting oil pump. The use of the main oil pump can not only save plant power, but also prevent the risk of oil interruption and tile burning due to the power outage of the AC lubrication pump.

The function of the Steam turbine AC lube pump  125LY-35-8 is to prevent damage to the turbine and reduce the turning power of the turbine. The oil source of the top shaft oil pump comes from the lubricating oil behind the oil cooler, which can effectively prevent the oil pump from suction and cavitation. The top shaft oil pump will lift the large shaft and establish an oil film to prevent accidents such as damage to the oil film and bearing shells due to excessive weight of the shaft system during rotor rotation. The function of the AC/DC sealing oil pump is to provide air side sealing oil to the generator to prevent hydrogen leakage inside the generator.
