| Abstract: | In this paper, theoretical basis of the water hammer calculation was elaborated briefly. The water hammer＇s transient process of the thermal power station＇s make -up water system was simulated by computer software when the pump was stopped. The possibility of the hydraulic control butterfly valve and air valve used as protection during the pumping accident was analyzed and proved. The results show that the rational hydraulic control butterfly valve operation rules and air valve setting could prevent the water column separation. |
