| Abstract: | Failure of axis displacement safeguard, bring about harmfulness for safety and stable operation of the steamturbine suit. The C12-4.9/0.981 type steam-turbine suit axis displacement safeguard in a thermal power plant has been generally described and examined and repaired, and the trial operation and problems occurred being analysed. The solving method for some failures and equipment retrofitting measures was put forwad. Field test and operation prove that the effectiveness is obvious. |
