The steam turbine is a rotary steam power device, which converts the internal energy of steam into mechanical energy by utilizing high-temperature and high-pressure steam, so that a rotor provided with blade rows rotates and simultaneously does work to the outside. Because the steam turbine rotates under the high-temperature and high-pressure conditions, the function of the bearing is quite important, and the bearing is lubricated and cooled by lubricating oil. Lubricating oil enters the bearing through the bearing box from the lubricating oil pump outlet, returns to the bearing box directly, returns to the oil tank along the return pipe, and completes circulation. The oil quality of the lubricating oil has a great influence on the safe and economical operation of the whole turbine. Poor oil quality caused by dirt of the bearing box can directly lead to abrasion of the bearing bush, equipment damage is caused, and cleaning of the bearing box is important.
