| Abstract: | The temperature of servomotor's oil cylinder concerning the highpressure governing valve of a 300MW unit NO.3 in Daba Power Plant is somewhat higher from the begining of putting into operation right up to now, some problems, such as upper seal leakage of the oil cylinder, agglomerition and carbon deposition of the pressure oil, deterioration of the oil quality, as well as frequent failure of the servo valve etc., have often occurred. For these reasons, a retrofitting scheme has been put forward, and after implementation of the said scheme, remarkable results having been obtained. |
