Details RTC aluminum roof exhaust fan: First, characteristics and application RAF series fan is the introduction of foreign advanced technology developed a new type of roof exhaust fan HTF, smooth exterior design of the product, the proportion of both said, sophisticated technology, in line with texture of high-end architectural requirements for exposed equipment. Specific air volume, high pressure, low power consumption, light weight, compact structure, etc., are widely used in machinery, chemicals, rubber, pharmaceutical, textile and other industries workshop plant and senior civil roof ventilation. Made of two structural forms: RAF type tapered wheels, twisted wing blade, suitable for low pressure, high flow ventilation occasions. RTCX-II-type centrifugal impeller HTF intelligent optimized exhaust fan, suitable for occasions require a higher pressure exhaust ventilation. According to the different transmission media, made of corrosion-proof type. Axial exhaust fan fire protection and insulation should be set motor in the fan air cooling system (using class H insulation class motor fan forced air cooling system may not be provided). Should not be below the motor insulation class F class. Axial exhaust fan fire motor power lead, should be inclusive or temperature thermal sleeve with high temperature cables. 1, leaf blower impeller structure should structure type high-efficiency, high intensity. Impeller diameter 630mm and above (including 630mm) axial fan blade should be made of high-strength aluminum alloy. The bidder shall describe the structure of the form of tender leaves the device. 2, axial fan motor direct drive motor should be used, the motor should be directly exposed to the air flow, centrifugal blower cabinet can be used in direct-drive or belt drive. Blower motor should be equipped with air-cooled, squirrel-cage, closed humid type of standard products, with full voltage starting, insulation class F. Exhaust fan motor should satisfy the exclusion of 280 ℃ smoke the whole process of running 0.5h. Bearing replacement period of not less than 30,000 hours. Select the device to start the motor to meet the requirements of the tender, full voltage starting current should be no more than seven times the full load current. 3, the damping device during assembly tender HTF Fire Co., static equilibrium prior to balancing its chassis vibration speed is not greater than 1.8mm / s roof exhaust fan HTF, suppliers should provide fans supporting the damper and fastening bolts. 4, manufacturing precision chassis fan casing shall comply with the relevant norms of the chassis motor bearings should be of sufficient strength and rigidity to withstand dynamic loads generated by the operation, the height should be maintained motor shaft and the housing center consistent. Axial fan casing should be hot galvanized, hot-dip galvanizing layer average thickness of not less than 70μm. Shandong Hongxin air-conditioning plant in Texas
