Fan Product Overview1. The use of fansT30 axial flow fan is widely used in factories, warehouses, offices, residential ventilation or enhance the heating within cooling purposes. Removing the base chassis, the fan can be used for free, can be installed in series in a long interval of the exhaust pipe, to improve pipeline pressure. By the fans should be no corrosive gas, no spontaneous combustion, no significant dust, its temperature must not exceed 45 °.BT30 explosion-proof axial fan impeller part aluminum production (excluding reel hubs), power switch explosion-proof motors, and explosion-proof switch or switch away from the explosive point. Other parts are the same as axial fan material, which is mainly used in chemical, pharmaceutical, textile and other industries and the carriage of flammable, explosive, volatile gases with the same mount technology and other arts and axial fans.2. fan typeThis fan total of 46 species, of which the blade, 6 blade, 8 blade peaceful settlement leaves nine machine number, press the impeller diameter, in turn arranged in ascending order: №3, №3.5, №4, № 5, №6, №7, №8, №9, №10; four of a total of ten blade machine number, according to the size of the impeller diameter, the order from top to large order is as follows: №2.5, №3, № 3.5, №4, №5, №6, №7, №8, №9, №10.3. The fan structureBy the fan impeller, housing and prejudices consists of three parts:(1) impeller - by the blade, wheels and other components. Blade steel sheet metal forming, press the desired mounting angle, welded to the outer hub. Impeller housing ratio (plate diameter of the impeller diameter than the shaft) is 0.3.(2) blade - are punched into similar figures, which installation angle: 3 into 10 °, 15 °, 20 °, 25 °, 30 ° five kinds; №4, №6, №8 sheet into 15 °, 20 °, 25 °, 30 °, 35 ° five. Impeller mounted directly on the motor shaft, which uses two 3 As the motor speed, №9, №10 use a motor speed, air flow range from 550 to 49,500 m3 / h, pressure in the range of 25 ~ 505Pa.(3) housing - made hairdryer, undercarriage and other components, undercarriage and is divided into two sections with sheet steel.(4) the transmission part of the spindle, bearing housing, coupling or composition leather one disc. Spindle with high-quality refined steel, bearings rolling bearings. The bearing housing in sufficient volume to place the cooling oil, and oil level control instructions to ensure proper operation.(5) Set the wind filter - an arc streamlined by sheet stamping, to reduce the loss of energy flow at the entrance.
