摘要
将泵站从启动至正常运行分为4个阶段,进行泵站启动扬程的分析计算。指出影响泵站启动扬程的主要因素有泵站启动时进水池和出水池的水位差、出水流道工作闸门的开启速度、出水流道的结构布置。通过对贯流式泵站启动过程进行分析,运用水力学原理,就泵站启动扬程的主要影响因素提出一种分析计算方法。以淮安第三抽水泵站为例进行泵站启动扬程分析及计算,所得结果与泵站的实际启动运行情况基本吻合。
The process of nmning a pumping station from start to operation is divided into four stages and the lift head during the starting period is analyzed. The main factors affecting the starting lift head are pointed out, including the water level difference between the intake sump and outlet sump during the starting period, the opening speed of the working gate and the structural layout of the outlet passage. In consideration of these three main factors, a calculation method for determining the starting lift head is proposed based on hydraulics principles. With the Third Huaian Pumped Storage Station as an example, the starting llft head of pumping station is calculated by use of this proposed method. The calculation results are in good accordance with the actual value.
