Detailed Product Description: | Axial exhaust fan when the A-type transmission using explosion-proof axial fans in the design, thermal insulation structure should be set up between the chassis and the motor. Speeding speed is 110% of the maximum operating speed, speeding time to less than 2min. Followed by our technical staff to introduce the assembly requirements axial flow exhaust fan. 1. Axial Radial clearance values ??fire smoke ventilation casing and impeller should be uniform, unilateral radial clearance values: When the machine number ≤No.10, the gap value ≥3.5mm; machine number> No.10 axis flow fan small gap ≥4.5mm. 2. Anti-smoke fan painted interior and exterior surfaces technical compliance JB / T 6886's. Fans paint chosen delivery 280 ℃ after fan media, paint almost no discoloration. 3. The inlet and radial impeller wheel cover unilateral import clearance should be uniform, unilateral radial clearance value should be within the range of 0.15% to 0.4% of the impeller diameter, inlet and impeller cover the axial length of the overlap should be impeller 0.8% to 1.2% of the diameter. After the above introduction, if you are using axial flow exhaust fan in the process, there is no place you do not understand, you can always contact us. Axial fan design programs. The two axial fans unite use, which need a more rational design, it can be run better. Put an impeller mounted on the back of another impeller, and the impeller turning opposite to each other, called rotating axial flow fan. Because of this structure may be omitted in the middle and rear fixed vanes, and small eddy current losses, with the transmission loss, high pressure, high efficiency wide range, high efficiency characteristics, so to become China's coal mine, rail and road tunnels widely used in engineering ventilation. In the design, many users request the ventilator designed not only to meet the long-running condition, but also to meet the other conditions of the other speed requirements, and traffic between these conditions and the pressure difference is great, can not adopt the mold design to achieve. This requires the design phase must know the fan performance curve, and thus need to take into account the multiple conditions by optimizing the design.
