Abstract

Abstract: In order to reduce power consumption, the speed of the induced draft fan of Sanhe Power Generation Corporation Limited is controlled by hydraulic coupling. But the oil temperature of hydraulic coupling was too high, so the combined adjustment mode of hydraulic coupling and regulating damper had been adopted. The regulating damper was adjusted in a smaller range in long time; therefore the actuating element was worn seriously and caused the damper jam. The material of regulating damper actuating element had been replaced, and the unit normal operation was ensured.

Key words: induced draft fan, hydraulic coupling, regulating damper, jam
