HTF Fire Fighting Tobacco has good high temperature resistance, high efficiency, less occupying land than centrifugal, and convenient installation.The qualified product from the factory is under the amount of air, and the full pressure error does not exceed ± 5%. The performance selection table is the performance in the standard state. The performance requirements of the technical documents or the order are based on the standard state.The performance listed in the table is the performance within the range of the*efficiency range. It is divided into five performance working points according to the air volume, and the performance table shall prevail when selecting.
Structure of HTF Fire Fighting Fighting Fan Fan:
The fan is mainly composed of the impeller, case, air inlet, motor and other parts.In addition to the above structure, N06C and NO8-20D also have the transmission part.
A. The impeller is a wing -type rear tilt, and the high -quality steel plate is used as the skeleton. After the special process is treated, the glass fiber reinforcement layer is made according to a specific process.High strength, good air dynamic performance, two balance accuracy reached G5.6 level, and the overall operation is stable.
B. The shell is made by the glass reinforcement reinforcement.The NO16-20 shell is made into a three-way formula for installation and repair or removed the impeller.The inner surface is smooth and the resistance is small; the air inlet produces the overall convergence of the FRP. After processing, it is fixed on the side of the shell entrance with screws. The accuracy is high, which can make the gas enter the impeller smoothly and the flow resistance is small.
C. Transmission group: Fan of four transmission methods: A, B, C, and D type.The main axis is made of high -quality steel, and there is a special protective layer at the contact with the corrosive gas. The structure is simple and convenient for maintenance.
D. The bracket is welded by A3 steel.
The three major installation specifications of HTF Fire Fighting Fire Formula:
① Fire fire exhaust fan should be set up in a dedicated fan room or on the outdoor roof. The fan room should be separated from the 5 -wall wall with a refractory limit of not less than 2h and the 1.5h floor -level fire door.
② When the conditions are limited, it can be set in a dedicated space. The surrounding surroundings of the space should be used to use non -combustion body with a refractory limit of not less than 1h, and there should be space of more than 600mm on both sides of the fan.
③ When the machine room must be used with other fan, it is necessary to ensure that there should be an automatic water spray fire extinguishing system in the machine room; a fan and pipe for pipes used for pressurizing the air supply;take over.
