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. At rated speed in the work area, fans of the measured pressure curve with the description given in the curve should meet the following requirements: axial-flow exhaust fan at a predetermined flow rate, corresponding to the pressure deviation of ± 5 %. Centrifugal exhaust fan at a predetermined flow rate, corresponding to the pressure deviation of ± 5%. The fan uses a special compartment temperature measures built cycle impeller can forcibly cool the motor, ensure that the motor temperature does not exceed a predetermined value. Run at 400 ℃ 100 minutes or more, long-term operation at 100 ℃. Can play a role of ventilation and fire smoke. The product was identified as Shandong Provincial Fire Department fire products sentinel production. YTPY type, fire temperature exhaust fan with high efficiency, smooth operation, low noise, high-temperature structure is reasonable, easy to install, can be vertical, horizontal and hanging installation. The fan is designed with special air-cooled motor cooling system built-in motor type; the use of advanced aerodynamic design of the blade (swept forward, forward) Vertical exhaust fan, so noise than existing fire fans 2, low 8-10dB (A ) low power 6%; the main air duct medium temperature of 280 ℃ when more than 30 minutes of continuous operation, 150 ℃ when the long-term continuous operation. Product Attributes This fan uses a special compartment temperature measures built cycle impeller can forcibly cool the motor, ensure that the motor temperature does not exceed a predetermined value. Can run more than 100 minutes HTF-1 exhaust fan at 400 ℃, long-term operation at 100 ℃. Ventilation and fire smoke can play a role in the product altogether divided into: ① ② atmospheric pressure single-speed two-speed single-speed ④ ③ MV MV dual-speed four series. The fan uses a special compartment temperature measures built cycle impeller can forcibly cooling the exhaust fan motor, ensure that the motor temperature does not exceed a predetermined value. Run at 400 ℃ 100 minutes or more, long-term operation at 100 ℃. Can play a role of ventilation and fire smoke.
