適用于中高水頭，一般100－500米。其特點是利用水流動能沖擊轉(zhuǎn)輪旋轉(zhuǎn)作功，且噴嘴的射流中心與轉(zhuǎn)輪在同一平面上。沖擊式水輪機結(jié)構(gòu)緊湊，運行穩(wěn)定，操作方便，適用于負荷變化大的電站。

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、斜擊式、和雙擊式三種類型。

There are three types of impulse turbines:Pelton 、Turgo and Crossflow.
