The oil level in the axial fan reducer is displayed on the outer level gauge of the air cylinder through the oil pipe at the bottom of the gearbox. The SL98 fan tubing is made of galvanized carbon steel pipe. A corrosion hole with a diameter of about 5mm is found at the bottom of the tubing 600mm away from the gearbox. The leaking lubricating oil falls on the cooling tower receiving layer below the fan. Due to the small aperture, The amount of oil leaked per unit time is small, and a large amount of water vapor is flushed in the air cylinder, so there is no oil layer accumulation on the surface of the water collector below the leak point. The system uses boric acid bromine solution as a daily biocide. Due to the action of the biocide and the wind blown by the fan, the water vapor in the cooling tower air duct often contains bromide ions. Carbon steel without anti-corrosion measures is prone to pitting corrosion under the action of halogen ions, and the pores produced by pitting corrosion are mostly small and are usually covered by corrosion products or deposits, so it is difficult to find holes. . The water vapor entrained with bromide ions rises under the action of the wind blower of the fan, and adheres to the bottom of the oil pipe outside the base of the SL98 fan, causing pitting corrosion on the surface. Due to the covering of corrosive materials, no attention is paid to the routine inspection of the fan, which eventually leads to the perforation phenomenon. happened.
