Products; 1.HTF type fire temperature exhaust axial fans, the basic form of axial-flow structure, the use of high temperature motor, arranged a special exhaust fan motor cooling system htfc products by the National Fire Equipment Quality Supervision and Inspection Center Press GA211-1999 "fire exhaust fan high temperature test method" test temperature at medium temperature 300 ℃ high temperature over 60 minutes of continuous operation at a temperature of 100 ℃ conditions of continuous operation 20 hours / times without damage, smoke ventilation can be dual-use. 1.2 Installation divided by Product Category: Horizontal and roof type (W type). Divided by the amount of wind pressure: atmospheric model have type Ⅰ, Ⅱ (double speed); medium-pressure (for mixed flow impeller) has Ⅲ, Ⅳ type (double speed); there is low pressure type D1, D2 type. By the governor points: single-speed, two-speed, frequency (frequency conversion motor with inverter controller, the implementation of frequency control, in order to adapt to different conditions, it is recommended to adjust the frequency locked in 25Hz ~ 50Hz). 1.3. In order to meet the requirements of different places of noise, the fan can be equipped with different lengths muffler, can also be made sheathed (housing silencer). 2, HTF-type fire temperature exhaust axial fans working conditions Operating temperature: -20 ℃ ~ + 60 ℃ (continuous operation); temperature: 100 ℃ (20 hours of continuous operation), 300 ℃ (60 minutes of continuous operation ); temperature: <90%; medium conditions: air (dust content of no more than 100mg / m3); Power supply: three-phase, 380V / 50Hz; 3, HTF-type fire temperature exhaust fan axial fan applications can be widely used rise construction, oven, underground garage, tunnels and other places smoke ventilation. The fan uses a special compartment temperature exhaust fan chart measures built motor forced circulation cooling impeller can ensure that the motor temperature does not exceed the specified value. Be able to run more than 100 minutes exhaust fan type at 400 ℃, long-term operation at 100 ℃. Can play the role of ventilation and fire smoke. The product was identified as sentinel Shandong Province Fire Department fire products production. YTPY type, fire temperature exhaust fan with high efficiency, smooth running, low noise, high temperature and reasonable structure, easy to install, can be vertical, horizontal and hanging installation. The fan design has a special built-in motor cooling system air-cooled motor types; uses an advanced aerodynamic design of blades (forward-swept, forward), the noise 2. Low 8-10dB (A) 6% lower power than existing fire fans ; main duct medium temperature of 280 ℃ when more than 30 minutes of continuous operation, 150 ℃ when the long-term continuous operation. Product Attributes The fan uses a special compartment temperature measures, built on the motor cycle forced cooling impeller can ensure that the motor temperature does not exceed the specified value. To operate at 400 ℃ 100 minutes or more, long-term operation at 100 ℃. Ventilation and fire smoke can play the role of the product is divided into: ① ② atmospheric pressure single-speed two-speed ③ ④ MV MV single-speed two-speed four series.
