Abstract:
(EN) This control device controls the temperature of a shaft seal portion provided around a rotating shaft of a rotating machine to an appropriate temperature by adjusting a supply amount of cooling air supplied to the shaft seal portion. The control device calculates a sensitivity exhibited by the temperature of the shaft seal portion with respect to the flow rate of the cooling air supplied to the shaft seal portion, and controls the flow rate of the cooling air on the basis of the calculated sensitivity in such a way that the sensitivity attains a predetermined target value. In calculating the sensitivity, the flow rate is varied within a predetermined range about a certain flow rate. The temperature sensitivity at the central flow rate is calculated from the variation in the temperature of the shaft seal portion with respect to the variation in the flow rate.
(FR) L'invention concerne un dispositif de commande qui commande la température d'une partie joint d'arbre disposée autour d'un arbre rotatif d'une machine rotative à une température appropriée par réglage d'une quantité d'alimentation en air de refroidissement fournie à la partie joint d'arbre. Le dispositif de commande calcule une sensibilité présentée par la température de la partie joint d'arbre par rapport au débit d'air de refroidissement fourni à la partie joint d'arbre, et commande le débit d'air de refroidissement sur la base de la sensibilité calculée de telle sorte que la sensibilité atteint une valeur cible prédéterminée. Lors du calcul de la sensibilité, le débit varie dans une plage prédéterminée autour d'un certain débit. La sensibilité à la température au débit central est calculée à partir de la variation de la température de la partie joint d'arbre par rapport à la variation du débit.
(JA) 制御装置は、回転機械の回転軸周りに設けられた軸封部の温度を、軸封部に供給する冷却空気の供給量を調整することにより、適切な温度に制御する。制御装置は、軸封部に供給する冷却空気の流量に対する軸封部の温度が示す感度を算出し、算出した感度に基づいて、感度が所定の目標値となるように冷却空気の流量を制御する。感度の算出にあたっては、ある流量を中心として、所定の範囲で流量を変動させる。流量の変動に対する軸封部の温度の変動から中心となる流量における温度の感度を算出する。
