Abstract

Спіральний відцентровий вентилятор утворений конструктивним вузлом, що містить всередині циліндричного кожуха (1) лійку (2) конвергенції повітря і лійку (3) дивергенції повітря, між якими знаходиться канал проходження повітря, гвинт (4) нагнітання повітря, пов'язаний з привідним двигуном (5). Для покращення звукоізоляції лійка (2) конвергенції повітря, яка діє як вхід для повітря спірального відцентрового вентилятора, і лійка (3) дивергенції повітря аксіально відділені одна від одної, причому між найвужчими їх частинами встановлений звукопоглинач (7). При цьому гвинт (4) розташований у лійці (3) дивергенції повітря.Spiral centrifugal fan formed by a structural unit containing inside the cylindrical casing (1) funnel (2) air convergence and funnel (3) air divergence, between which there is a passage of air, screw (4) air injection associated with the drive motor ( 5). To improve the sound insulation, the air convergence funnel (2) acting as an air inlet for the spiral centrifugal fan and the air divergence funnel (3) are axially separated from each other, with a sound absorber (7) installed between their narrowest parts. The screw (4) is located in the divergence funnel (3).
