GYF fire temperature exhaust axial fans Overview 1. Purpose: GYF fire temperature exhaust axial fans tested in accordance with GB50045 ~ 95 "fire protection design of tall buildings" and GB50067-97 "garage, repair garage, parking lot design fire norms ", is a new type of energy-saving fire exhaust fan. The fan can be used as various buildings dedicated fire smoke, but also for high-rise buildings, general building, underground garage, culverts and other mines of smoke and ventilation, such as underground repository for exhaust ventilation usually requires When the winds of revolution with smoke. 2, Structure: leaf type with axial flow: There GYF-I (single speed) and GYF-SI (double speed); two kinds of fire exhaust fan. Leaf type with oblique flow: There GYF-II (single speed) and GYF-S2 (double speed) of two fire exhaust fan. If users have higher requirements on noise, you can make GYF-BX silencer exhaust fan the fire. Fans can also be made use of vertical exhaust fan mounted on the roof to do with fire smoke. GYF fire temperature exhaust axial fans consists of five main components: (1) the impeller (2) motor (3) circulating air impeller (4) guide vanes, the inner tube, guide holes (5) of the outer cylinder. 3, install and use: 1) can be vertical, horizontal and hanger installation. Fan base must be natural combination exhaust fan base plane, and not beat coupling force base, the weight of the pipeline must not be applied to the turbine components. 2) should be carefully checked before installation whether the impeller and the casing due to transport damage and deformation and, if exhaust fan buy, should be repaired before installation. 3) Check for loose bolts, exhaust fan motor insulation is good maintenance, the availability of goods hinder the rotation within the fan duct. Staff carefully check the fan has no deformation or damage during transport, the fan is off or loose fasteners, impeller if there collision phenomenon, and the various parts of the fan to be checked. If found abnormal, should repair, etc. before use. Staff members must be prepared a variety of tools, materials and site installation of exhaust fans when needed, more expertise, please visit our website for online counseling and referral.
