HTF (B) series of fire temperature exhaust fan

HTF (B) fire temperature exhaust mixed flow fan or call PYHL-14A fire exhaust fan, which uses multi-objective optimization design CAD software, matching molded cone twisted wing impeller, high temperature fully enclosed motor built, arranged a special motor cooling system. Use two-speed motor direct-drive, to one machine (that usually send row when high-temperature exhaust ventilation and firefighting), arranged after the electrical control box can be remotely controlled automatically. High temperature performance, air volume, high pressure, easy installation, etc., are widely used in high-rise buildings, drying room, underground garage, subway tunnels and other occasions to send fire smoke and exhaust ventilation. Press GA211-1999 Fire fan high temperature test methods, can run at 400 ℃ more than 100 minutes of continuous high temperature, medium temperature at 100 ℃ continuous operation 20 hours / time is not damaged, it has been approved for use by fire departments in major cities nationwide. First, the structural characteristics of the main blower fan blade, housing, collector, silencer, guide vanes, the motor components. Meridian impeller has accelerated features twisted plywood sheets welded to the hub. High temperature testing, bearing temperature, noise, balancing check, speed test, a very good aerodynamic performance. The housing is made cylindrical, and mute function concentrator is coupled into one. Export loaded baffle, with good airflow enacted, the pressure is stable. PYHL-14A-type fan motors with separate chambers, avoid direct contact with the gas and motor design secondary air, enabling to reduce the ambient temperature of the motor. Second, the ventilation and the use of fire temperature exhaust fan HTF (B) fire temperature exhaust mixed flow fan and wide application tunnels, underground garage, senior civil construction, metallurgy, mines and other places, HTF (PYHL-14A) series fan operating temperature of 300 degrees Celsius. Adhesive materials are allowed within the gas contained in the dust and hard particles is not greater than 150mg / m3. Special environment can choose Francis fan explosion-proof, anti-corrosion Francis fan. Third, select the fan performance fan performance of the Company's performance on access to information, property listed in the table is the most efficient performance within the range, according to traffic divided into five characteristics, according to prevail in the selection of the performance table, the factory fan Qualified performance under full pressure rated flow value does not exceed + _5%. Performance selection table is performance under standard conditions, regardless of the state performance standards according to technical documents or orders subject to the requirements of the standard state atm = 101325pa, t = 20 = 50% relative humidity of air condition, when the actual conditions above are not when according to the relevant formula in line with the conversion, installation can take the form straight horizontal floor installation and ceiling, floor installation requires the installation of damping systems; high-strength spring shock pad, rubber cushion, lifting using hangers Incoming with screw fixation, the installation of effective attenuation of the vibration damping system of the machine itself, to reduce vibration forces rumored to prevent vibration force, to ensure the normal operation of the fan increase. As noted in vertical installation in the order, such as high flow, high pressure, installation dimensions and performance of the Company and other performance parameters differ with special requirements, the company will provide customers with special specifications to meet the requirements of wind turbine design.
