| Abstract: | The author describes the process of the application of EV2000 frequency converter control system to the auxiliary oil pump of Air Separation System 4, Tiantie Power Plant, analyzes failures such as oil overflow and oil pressure fluctuation, and proposes an improvement plan. After modification, the failures were eliminated, the speed and start/stop of closed-loop controlled pump realized, and the impact on and vibration of motor and power grid reduced. Equipment reliability was increased, motor service life prolonged and smooth production ensured. |
