摘要
以一矿井水抽排工作为例,介绍了水泵排水扬程计算过程中管路沿程损失和管道局部水头损失的计算方法,为排水系统泵的选型设计提供了有益借鉴。
An introduction is made in the paper to the methods for determining the head loss along the total length drainage pipe and the local head loss of the piping system in calculation of the pumping head, with the mine water drainage operation at a coal mine cited by way of example. This provides a useful reference for the design or selection of water pump for mine water drainage system.
