Optimizing Drainage System of Turbine Head Cover Based on Siphon Principle
The drainage system of turbine head cover is the core of the safe and stable operation of the unit.When the main water supply method of the unit is head cover water intake,the head cover will have the problems of large water leakage,long startup time of submersible pumps,high equipment loss rate,and the risk of flooding the powerhouse.In view of this situation,this paper proposes a corresponding transformation program from the actual situation of the Miao-wei power station,and makes a comparative analysis with the operation situation before transformation.The results show that the power consumption cost of the siphon drainage system of head cover after the modification is only 0.976%of that before the modification,and the cost of the modification can be recovered in a short period of time;The modification makes the drainage efficiency of water head cover increase by 84.2%.This modification reduces the operation and mainte-nance cost of the equipment,extends the service life of the equipment,and significantly improves the drainage efficiency,which provides a guarantee for the safe and stable operation of the unit.
