Structure T35 series axial fan through simulation studies to determine the turbine airfoil, using a cylindrical hub structure square axial fan motor has been modified design, reducing the flow loss proof axial fan model structure and thus the efficiency of the fan outlet area of ??a circle is calculated by up to 77 percent, according to exit the ring area calculation increased to 89.5%, lower than the A sound level of 3.6 dB. T35-type axial fan by the impeller diameter is divided into 13 gauge t35-11 axial fans, in order of priority is: №2.8,*,3.55,4,4.5,5,5.6,6.3,7.1,8,9, 10,11.2. Each gauge is divided into 15 °, 20 °, 25 °, 30 °, 35 ° and other five kinds of blade installation angle. The wind direction and the axis is parallel to the axial fan called, (such as the exhaust fan the fire) is the centrifugal fan axial fans Conversely, the majority of the fan blades and motor combination can be sized according to the amount of wind pressure. General axial fans centrifugal fan than an advantage in portfolio selection and a large amount of wind pressure on the (mainly refers to the fan efficiency and noise performance)! Centrifugal fans and axial fans difference is: 1, changed the flow of centrifugal fan duct within the media, but does not change the flow of axial fan duct within the medium; 2, the former air volume and pressure are large, the former air volume and pressure are very low ; 3, the former is more complex installation, which is relatively simple to install; 4, the former general and fan motors are connected via the shaft, which is usually in the fan motor; 5, the former often installed in the air conditioning unit inlet and outlet of the boiler drum , fan, etc., which were often installed in the duct or duct exit the front roof axial fans, air conditioning Chenyu factory outlets (certified), axial fan Chengde City by Wu Chen Yu Air Conditioning Equipment Co. . Wu Cheng Chen Yu Air Conditioning Equipment Co., Ltd.
