HTF high temperature fire smoke exhaust Fan Low noise Fan box High temperature resistance Axial flow fan - --Introduction to fire smoke exhaust fan - more details can be consulted: Liu Gong 189-7994-6966
The fire smoke exhaust fan has the advantages of excellent high temperature resistance, high efficiency, small size, simple installation, etc. It can be used as a temperature resistant, moisture resistant, corrosion resistant type Roof fan , used in roof smoke exhaust aeration 。
1. The installation mode of the fan can be divided into horizontal type and roof type, with special requirements for air volume, total pressure, installation size and other performance;
2. HTF - Ⅰ and HTF - Ⅱ are normal pressure fire high temperature smoke exhaust fans, and the blade type is axial flow type: HTF - Ⅰ (single speed) And HTF-II (two speed); HTF - Ⅲ and HTF - Ⅳ refer to medium pressure fire fighting and high temperature smoke exhaust system;
3. HTF-X is designed for silencing fire fighting and high-temperature smoke exhaust With fans, users can choose different types according to actual needs;
4. HTF-W series roof type high temperature smoke exhaust system With fan, users can select flame retardant type according to actual needs FRP Hood or steel hood;
5. HTF-D is a low pressure fire high temperature smoke exhaust fan;
Features of fire high temperature smoke exhaust fan
1. High temperature resistance performance: the fan test meets the requirements of GA2l-1999 Test Method for High Temperature Resistance of Fire Smoke Exhaust Fans, establishing a high ten standard The standard enterprise internal control guarantee system can operate continuously for 45 minutes at 300 ℃ and 20 hours at 100 ℃ without damage. It is widely used in high temperature Class civil buildings, ovens, underground garages, tunnels and other occasions;
2. Applicable scope Enclosure: variable speed or multi speed drive can be adopted according to the different requirements of high satin civil buildings to achieve the purpose of one machine for two purposes (i.e. common ventilation and exhaust and high temperature smoke exhaust during fire fighting). The blade type is divided into axial flow (HTF -1. II) and mixed flow (HTF-I G、 IIG), so that the fan has a wide range of performance parameters. If the user has high requirements for noise, it can be made into a silent fan;
3. High efficiency: this series of fans adopt the first Advanced CAD system software, new products developed by light multi-objective optimization design, shoes actually measured, fan efficiency greater than 80x The flat efficiency curve is conducive to energy saving;
4. Convenient installation and small size: the basic type of the fan is axial flow fan, which can be directly connected with Air duct Connection and wall installation (installation can be vertical, horizontal or hoisting). Roots save too much floor space. At the same time. It is not affected by large size and large air volume electric machinery Direct connection mode, so that its operation can Shit.
Shell: surface quality of fan box
The casing of the eighth degree fan adopts excellent Q235 Benxi Steel Hot Rolled carbon steel Plate, with high characteristics Corrosion resistant. The company owns the first Progressive laser cutting The surface of the plate is free of scratches, and the appearance is bright. The inner layer of the plate is coated with anti-corrosion and antirust paint, and the outer layer is made of high-grade gray, with two layers of paint to ensure that the equipment is long under outdoor working conditions No rust.
electric machinery
Eight degree fan adopts production motor production equipment and fan specialty with complete inspection procedures The matching motor has passed ISO9001 and high temperature 3C certification for fire protection Explosion certification and energy efficiency label. The motor shall be closely matched with the fan load and adopt B3 mounting structure. The protection class of the motor is IP54, the insulation class is F, and the temperature rise class is B. Motor bearings shall be ball type, non lubricated. The power reserve coefficient of the motor shall be taken as 110% to improve the safety of the fan Completeness.
impeller
Discard the old method used by domestic manufacturers, use rough rough template for blade blanking, and use manual positioning method for welding or riveting hub and blade to shape the impeller The angle deviation of the rear blade is too large, which directly affects the use efficiency and noise.
The blades of the octave fan are designed through multi-objective optimization according to the principle of aerodynamics. The hub is formed by stamping. The connection between the impeller and the blade is riveted or welded after profiling, which has the advantages of correct installation angle and small deviation. Each impeller is subject to static and dynamic balance verification. The impeller shall be statically and dynamically balanced, Meet the G2.5 balance level of international standards.
Motor terminal box
As the motor is located inside the fan, the Supplier shall provide a motor junction box to connect the outside of the induced draft fan Explosion type, ordinary type and other applications shall be equipped with correct junction box type.
