Abstract

See full text

An axial flow fan with high-temperature resistance for a ship desulfurization system includes a fan casing, axial flow fan blades, a high-temperature resistant bearing, and a cold water pipe. The axial flow fan blades are coaxially configured at an inner front end of the fan casing, and a rotating shaft is inserted in a middle of the axial flow fan blade. A middle part of the rotating shaft is sleeved with two high-temperature resistant bearings, and outsides of the two high-temperature resistant bearings are fixedly provided with a cruciform axis support. A rear end of the rotating shaft is sleeved with a worm gear, and an upper end of the worm gear is provided with a worm. The worm gear meshes with the worm. The worm gear and the worm are configured inside a lubricating oil casing, and the lubricating oil casing is covered with the insulating layer.
