Местные отсосы при ручной электросварке
Панели равномерного всасывания (панель Чернобережского)
По типу серии 4.904-37
Панели равномерного всасывания предназначены для удаления вредных выделений при сварке изделий на стационарных местах. Приведены конструкции односторонних и двухсторонних панелей трех наиболее применяемых типоразмеров панелей как с верхним, так и с нижним забором воздуха 600х645, 750х645, 900х645. Живое сечение составляет 22,5% от фронтального сечения панели. Скорость воздуха в живом сечении рекомендуется применять в пределах 3-4м/сек, при этом объем воздуха, удаляемого с м2 фронтального сечения панели должен составлять 3300м3 /час. Коэффициент местного сопротивления панели §=1. Угол наклона воздухозаборной плоскости панели к вертикали составляет 35°, что существенно снижает неравномерность забора удаляемого воздуха по всей фронтальной плоскости панели.
Всасывающая решетка предусмотрена сварной из отдельных гнутых перьев.
Возможно изготовление панели равномерного всасывания для удаления вредностей в зоне заливки литейных конвейеров по типу серии 4.904-45, принцип работы которой аналогичен. Разница в габаритных размерах и толщине металла.
Панели равномерного всасывания типа 1П6; 1П7,5; 1П9
Панели равномерного всасывания типа 3П6; 3П7,5; 3П9
Панели равномерного всасывания типа 2П6; 2П7,5; 2П9
Панели равномерного всасывания типа 4П6; 4П7,5; 4П9
