Exhaust fan for the selection of the main control parameters temperature, air flow, total pressure, efficiency, noise, electrical power, speed and shaft power. Exhaust fan at a temperature not higher than 85 ℃ conditions should be long-term normal operation. Exhaust fan shall ensure that: When the transmission medium temperature at 280 ℃ when continuous work 30min, and still continuously at medium temperature cooling to ambient temperature during normal operation. 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 exhaust, exhaust fan applications, such as underground library usually used for row air ventilation, smoke with winds of revolution when needed. 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 vertical, 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 naturally be combined with basal plane, and not to beat the base force coupling, Cangzhou exhaust fan, 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 so, exhaust fan maintenance, should be repaired before installation. 3) Check for loose bolts, electrical insulation is good, whether the goods hinder the rotation within the fan duct. Exhaust fan maintenance, up Swiss mechanical and electrical (online consultation), Cangzhou exhaust fan ventilation and air conditioning provided by the liter Swiss mechanical and electrical equipment factory. L Rui HVAC Electrical Equipment Factory (www.dzsrxfkt.com) is an industry leader in Shandong Dezhou, fans, ventilation equipment, over the years, the company implement the scientific management, innovation and development, the principle of honesty and trustworthiness, and satisfy customer needs. In liters Swiss electromechanical leadership with the staff warmly welcome all inquiries negotiations to create liter Swiss electromechanical better future.
