[Tianjin Jinzhong Ji HVAC purification equipment to recommend the star product --HTF exhaust fan fire] 1, the performance of the fan performance table is listed in the most efficient range of performance, according to the air volume is divided into five performance operating point, according to prevail in the selection of the performance table. Factory fan qualified under rated air flow, total pressure value error does not exceed ± 5%, the performance of the selection table is a performance standard state, regardless of the technical documentation or performance are subject to the requirements of the standard state orders; 2, the fan installation can be divided into horizontal and roof type, for air flow, total pressure, mounting dimensions and other properties have special requirements; 3, HTF-Ⅰ, HTF-Ⅱ, said pressure type fire temperature exhaust fan, leaf type with shaft Streaming: HTF-Ⅰ (single speed) and HTF-Ⅱ (double speed) of two; HTF-Ⅲ, HTF-Ⅳ representation pressure fire temperature exhaust professionals; 4, HTF-X for the fire temperature exhaust silencer fan, the user can choose according to the actual needs of different types; 5, HTF-W Series rooftop fire temperature exhaust fan, the user can choose according to the actual needs of flame-retardant fiberglass hood or steel hood; 6, HTF-D for low pressure type fire temperature exhaust fan; 7. Special Note: GYF and HTF series fan is similar products. [Tianjin Jinzhong Ji HVAC purification equipment to recommend the star product - Fan Fan] including centrifugal fan and axial fan. (1) structural characteristics and uses centrifugal fan. Centrifugal fan from the air inlet, the impeller, volute spindle, the outlet diffuser, the basic portion of the air outlet, and the like. When the impeller rotates, the gas through the gas inlet axial suction, and then turn off the gas 90 °; flowing leaf blower Road, is the impeller Shuaixiang volute heaters, through centralized, diversion, and then the diffuser by exports discharge centrifugal fan commonly used in low flow, high-pressure exhaust fan sites, almost all optional AC motor drive, and according to the requirements of axial fans, such as dust emission, high temperature, explosion, etc., use of different types of motors. Centrifugal fan according to different uses can be divided into: general ventilation centrifugal fan, boiler centrifugal pass (lead) fan, coal fan, Pai dust centrifugal fan, centrifugal fan of mine, explosion-proof centrifugal fan, corrosion centrifugal fan high temperature centrifugal fan, centrifugal fan grain powder delivery. (2) axial fan structural characteristics and uses. Axial Fan by wind-collecting device (plenum), impeller, diffuser, diffuser (diffusion tube) and other major structural components. Gas from the set of wind enters through the impeller of the gas for energy, and then into the guide vanes, vane airflow deflected part of the kinetic energy into static pressure energy. Finally, the air flow through the diffuser portion of the axial flow kinetic energy into static pressure energy, and then out of the input pipeline system. Axial fan types and structures are diverse, small axial fans, its just over 100 mm impeller diameter, larger diameter is up to more than 20 meters. Axial fan according to the direction of the axis configuration can be divided into vertical and horizontal.
