摘　　要：鉴于黄河多泥沙的特点,小浪底电站技术供水系统在设计上采用了蜗壳水、清水2种水源。清水系统存在回水泵房安全性低、回水泵抽水能力不足、水源供水能力不足的问题。随着小浪底水库的逐渐淤积,技术供水各部冷却器均有不同程度的泥沙淤积,通过采用混合供水、降低流量等措施保证了当前水沙条件下各冷却器不淤积。In view of the sediment of the Yellow River,the technical water supply of Xiaolangdi hydropower station is designed to use both spiral case water and clean water.The clean water system has several problems,such as low security of the pump room,low deficiency of the water pumping ability and the deficiency of underground water supply capacity.As Xiaolangdi reservoir sedimentation grows,the various parts of the technical water cooler have different degrees of sediment.Measures such as use of mixed water supply and reducing water supply helps to ensure the sediment to be deposited on the cooler under the present conditions.
