污水泵站高位井水力模型试验

Hydraulic model tests for head tank of sewage pumping station

摘要: 采用水力模拟的方法对两个不同结构尺寸的污水泵站高位井的水流流态、泥沙淤积及水头损失等进行了模型试验．试验结果表明，出水池长度较长，收缩角较小的高位井中的水流流态较好，但池内泥沙淤积程度较重．随着水泵开泵台数的增加和进水流量的加大，可改善池内的泥沙淤积．

Abstract: The flow regime, sediment deposition and the loss of head of two head tanks of the sewage pumping station with different dimensions are studied by using a hydraulic model test method. Test results show that the flow regime is good in a head tank with a greater length of the outlet pond and a smaller contract angle, while the sediment deposition is heavy. The sediment deposition decreases with the increase of the number of running pumps and the inflow discharge.
