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), the noise 2. Low 8-10dB (A) 6% lower power than the existing Fire fans ; 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 measure exhaust fan purchase, the built circulating 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 ℃. 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. GYF fire temperature exhaust axial fans Overview; 1, use: 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 protection "exhaust fan, 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 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. Two-speed exhaust fan in high-rise building fire smoke system for high-level basement usually work accident smoke exhaust state two-speed, two-speed asynchronous motor is particularly suitable. Switch to low-speed two-speed fan operation The synchronous speed exhaust fan to improve the lot of the principle, the amount of exhaust greatly improved accordingly, then the system immediately replaced by the exhaust smoke condition. But in the design process, will encounter Electric two-speed fan control problems, that is how to solve the motor windings from Δ-connected to a dual-Y-connected conversion and interlock, fire linkage automatic and manual control; fan at high speed and reliability of protection shutdown how to maximize safety incidents smoke, how to ensure that the power supply and other issues.
