rising shaft
解釋
上行豎井-
K. t k : the shaft liner wall thickness change correction coefficient caused by temperature rising, the value dates from diagram 4
K . t k :溫升引起軸套壁厚變化校正系數,有圖4查出 -
At this time, the temperature of the shaft liner will reduce gradually, if the working time is shorter than the running time, the heat rising is low and the pv value is high
此時,軸套的溫升就逐漸下降。如果工作時間短於停止時間,則蓄熱少,溫升低,許用pv值就高些。
