Abstract

Wentylator osiowy zbieżny, zwłaszcza do przewietrzania chodników górniczych pod ziemią, składający się z silnika i wirnika, kierownicy strugi oraz osłony wlotu, obudowy wentylatora w kształcie stożka o malejącej zbieżności w kierunku przepływu powietrza, wewnątrz której ma posadowiony silnik z wirnikiem, charakteryzuje się tym, że pomiędzy średnicą wewnętrzną cylindrycznej części obudowy wentylatora (1), a najmniejszą średnicą wewnętrznej obudowy wentylatora (1) ma próg aerodynamiczny. Próg aerodynamiczny ma pochylenie w kierunku przepływu powietrza. Wielkość progu aerodynamicznego, utworzonego pomiędzy średnicą wewnętrzną cylindrycznej części obudowy wentylatora (1), a najmniejszą średnicą wewnętrzną obudowy wentylatora (1), jest większa lub równa odległości utworzonej pomiędzy średnicą wewnętrzną cylindrycznej części obudowy (1), a średnicą zewnętrzną wirnika (4).Converged axial fan, especially for ventilating underground mining walkways, consisting of engine and rotor, stream guide and inlet cover, fan housing in the shape of a cone with decreasing convergence in the direction of air flow, inside which has a motor with a rotor, it is characterized by that between the inside diameter of the cylindrical part of the fan casing (1) and the smallest diameter of the inside of the fan casing (1) has an aerodynamic threshold. The aerodynamic threshold has an inclination in the direction of air flow. The size of the aerodynamic threshold created between the inside diameter of the cylindrical housing of the fan housing (1) and the smallest inside diameter of the fan housing (1) is greater than or equal to the distance created between the inside diameter of the cylindrical housing part (1) and the outer diameter of the rotor (4).
