HTF series Smoke exhausting fan for fire fighting It is suitable for ventilation or high temperature smoke extraction in high-rise buildings, underground buildings, tunnels and drying rooms. It can run continuously for more than 30 minutes at 280 degree high temperature and continuously run 20 hours / times at medium temperature of 100 degrees Celsius. It is an ideal fire protection essential facility. The high temperature smoke exhausting fan has high efficiency, energy saving, stable operation, low noise, high temperature resistance, reasonable structure, easy installation and vertical, horizontal and hanging installation. The fan is designed with a special cooling system of motor cooling system, and adopts advanced aerodynamic design blades (forward and forward) to make noise less than 2 of the existing fire fans and 6% 8-10dB (A) power. The main duct medium temperature can run continuously for 30 minutes at 280 degrees centigrade, and it can run continuously for 150 consecutive days. According to the joint code issued by the State Administration of technical supervision and the Ministry of construction of People's Republic of China, the code for fire protection design of tall buildings (GB50045-95); "garage parking lot design code for fire protection" (GB50067-97); the "code for design of civil air defense underground" GB50038-94, which is qualified by the national fixed fire extinguishing system and the fire resistance component quality supervision and inspection center, The production license of Shandong fire products was issued by the fire brigade of the Shandong provincial public security department.
1. The performance listed in the performance table of the fan is the highest efficiency range, and is divided into five performance points according to the air volume. Under the rated air volume, the qualified value of the manufactured fan is less than + 5%. The performance selection table is the performance under the standard condition, regardless of whether the performance of the technical documents or the order requirement is in the standard state.
2. The fan installation method can be divided into horizontal and roof type, and has special requirements for air volume, full pressure, installation size and other properties.
3, HTF - I, HTF - II represent atmospheric pressure type high temperature smoke exhausting special fan, the blade type is axial flow type: HTF - I (single speed) and HTF - II (double speed) two kinds; HTF - III, HTF - IV indicate medium pressure fire - fighting high temperature smoke exhaust specially;
4. HTF - X is a muffler type special fan for fire and high temperature smoke exhausting. Users can choose different types according to actual needs.
5, HTF - W series roof type fire fighting high temperature smoke exhaust special fan, users can choose flame retardant glass steel wind cap or steel wind cap according to actual needs.
6. HTF - D is a low pressure type special fan for fire and high temperature smoke exhausting.
7, specify: GYF and HTF series fans are similar products.
1, fully familiar with the fan samples, familiar with the specifications and forms of fans, impeller rotation direction and air inlet and outlet direction, etc. before the installation of fans, check whether the impeller is rubbing or not, and conduct a comprehensive inspection of the components, whether the accessories are complete, whether the components are connected firmly, and carefully check whether the blades are damaged or deformed due to transportation, otherwise they can be installed after being repaired.
2. The air pipe connected with the inlet and outlet of the fan should have a separate support. It is not allowed to add the weight of the pipeline to the components of the fan. When installing the fan, attention should be paid to the horizontal position of the fan. The connection between the fan and the foundation and the outlet pipe should be adjusted so as to make it fit naturally and not be forced to join.
3. Smoke exhausting fan for fire fighting After installation, use hand or lever to pull the impeller, check whether there is too tight or rub touch phenomenon, whether there is no obstacle to rotation of goods, no abnormal phenomenon, only for trial operation, the wind opportunity transmission device exposed part should have protective cover (user provided). When the fan inlet is not connected to the pipeline, it is also necessary to purchase protective nets or other safety devices (user provided).
4, fan connection must be correct and reliable, fan casing should be properly grounded, grounding must be reliable. The power supply to the fan must be complete and meet the relevant requirements. Electrical wiring must have professional knowledge of electrical wiring.
