适用于中高水头，一般100－500米。其特点是利用水流动能冲击转轮旋转作功，且喷嘴的射流中心与转轮在同一平面上。冲击式水轮机结构紧凑，运行稳定，操作方便，适用于负荷变化大的电站。
Impulse turbine is applicable for different heads of 100-500meters.The feature is that it works by impulsing the runner to rotate with kinetic energy of water folw, and the jet center of nozzle and the runner are in the same plane.This kind of turbine shall be of compack conformation,reliable operation and convenient operation and appropriate to the power station of large load variation.
有水斗式、斜击式、和双击式三种类型。
There are three types of impulse turbines:Pelton 、Turgo and Crossflow.
