Abstract
Изобретение относитс к насосостроению и касаетс усовершенствовани центробежных самовсасывающих насосов рециркул ционного типа. Цель изобретени - повышение КПД путем снижени гидравлических потерь. Дл этого в рециркул ционном канале (К) б под углом /8 40-70° к его внутренней поверхности расположены лопатки 8, наклоненные в сторону впускного отверсти 7, плоскость среза которого расположена параллельно оси насоса. При выходе на насосный режим скорость циркул ции жидкости через К 6 значительно увеличиваетс под действием перепада давлени , создаваемого рабочим колесом 4, а в К 6 возникает вихревое течение, преп тствующее развитию пр мого потока. Благодар этому устран ютс паразитные перетечки, снижающие КПД. 1 з.п.ф-лы, 2 ил.The invention relates to a pump manufacturing industry and relates to the improvement of centrifugal self-priming pumps of recirculation type. The purpose of the invention is to increase efficiency by reducing hydraulic losses. For this purpose, in the recirculation channel (K) b at an angle of (8 40-70 & to its inner surface are the blades 8, inclined toward the inlet 7, the cut-off plane of which is parallel to the axis of the pump. When entering the pumping mode, the rate of circulation of the liquid through K 6 increases significantly under the action of the pressure differential created by the impeller 4, and in K 6 a vortex flow occurs that impedes the development of direct flow. This eliminates parasitic overflows that reduce efficiency. 1 hp ff, 2 ill.
