ЧТО ОЗНАЧАЕТ СЛОВО PELTON WHEEL
Pelton wheel
Колесо Pelton - это водяная импульсная турбина. Он был изобретен Лестером Аллан Пелтон в 1870-х годах. Колесо Pelton извлекает энергию из импульса движущейся воды, в отличие от мертвого веса воды, как и традиционное водяное колесо. Многие варианты импульсных турбин существовали до разработки Пелтона, но они были менее эффективны, чем дизайн Пелтона. Вода, оставляющая эти колеса, как правило, все еще имела высокую скорость, унося большую часть динамической энергии, приносимой на колеса. Геометрия лопастей Пелтона была спроектирована таким образом, что, когда ободок вращается на ½ скорости струи воды, вода оставила колесо с очень небольшой скоростью; таким образом, его конструкция извлекла почти всю энергию импульса воды, что позволило создать очень эффективную турбину.
Значение слова Pelton wheel в словаре английский языка
Определение колеса Пелтона в словаре - это тип импульсной турбины, в которой специально сформированные ведра, установленные на периметре колеса, поражены быстротекущей струя воды.

Impulse Turbines—Pelton Wheel In an impulse turbine the pressure energy of
water is converted into kinetic energy when passed through the nozzle and forms
the high velocity jet of water. The formed water jet is used for driving the wheel.
