Abstract
Изобретение позвол ет снизить уровень сиренного шума путем оптимизации взаимодействи потока с зыком. Вентил тор содержит корпус 1 с зыком 2 и расположенное в корпусе 1 рабочее колесо 3 с лопатками 4. Консольна часть 5 зыка 2 вдоль оси OOi рабочего колеса 3 выполнена гофрированной. Высота S гофров 6 со стороны рабочего колеса 3 составл ет 0,2 - 0,15 от шага tH лопаток 4 на наружном диаметре Он рабочего колеса 3, а угол раскрыти а гофра 6 равен 80 - 135°. Приведенные величины высоты S и угла раскрыти а гофра 6 позвол ют за счет оптимизации взаимодействи потока с зыком существенно снизить сиренный шум. 2 ил.The invention makes it possible to reduce the level of lush noise by optimizing the interaction of the stream with the language. The fan comprises a housing 1 with a tongue 2 and an impeller 3 with blades 4 located in the housing 1. The console part 5 of the tongue 2 along the axis OOi of the impeller 3 is corrugated. The height S of the corrugations 6 on the side of the impeller 3 is 0.2 - 0.15 from the pitch tH of the blades 4 on the outer diameter of the impeller 3, and the opening angle of the corrugation 6 is 80-135 °. The given values of the height S and the opening angle of the corrugation 6 make it possible, by optimizing the interaction of the flow with the tongue, to significantly reduce syringal noise. 2 Il.
