1、 Overview of T35-II (T40-II) series axial flow fan
The T35-II series axial flow fan is a new type of fan designed and improved based on the T30-II in China in the 1980s. Compared with the T30-II fan, it has obvious advantages: ① more reasonable structure: the hub is cylindrical, reducing flow loss, and the blade root has high strength; ② Significant improvement in performance; The total pressure efficiency is 89.5%, and the noise (compared to A-level) is reduced by 3.6dB (A).
This series of fans is suitable for transporting non explosive, non corrosive, and non significant dust gases. The ambient temperature should not exceed 60 ℃, and it is widely used for ventilation and heat dissipation in general factories, warehouses, offices, and residential areas. It can also be installed in series with long exhaust pipes to increase the pressure in the pipes. After removing the casing, it can also be used as a free fan.
The anti-corrosion axial flow fan (FT35-II type) is made of anti-corrosion material fiberglass processing, and the motor adopts a special anti-corrosion motor, which is used to transport corrosive gases to prevent sparks. It can also be produced as an explosion-proof fan according to user requirements (using explosion-proof motors). The performance parameters and appearance of FT35-II and BT35-II fans are the same as T35-11 fans. (If the fan motor needs to be equipped with single-phase or has special requirements for configuration, please specify when ordering).
2、 Installation of T35-II (T40-II) series axial flow fan
1. Before installation, the fan should be carefully inspected for any damage or deformation. If there is any damage or deformation, it should be repaired properly before installation can proceed.
2. During installation, pay attention to checking whether the connecting parts are loose, and the gap between the blades and the air duct should be even and not collide.
3. The weight of the connecting air duct should not be borne by the fan's duct, and additional support should be added during installation.
4. A collector must be installed at the negative end of the fan, and it is hoped that a protective net will be installed.
5. The fan base must be naturally connected to the foundation plane, and it is not allowed to forcefully connect the base by knocking it to prevent deformation of the base. During installation, the base should be calibrated, iron pads should be added, the basic horizontal position should be maintained, and then the anchor bolts should be tightened.
6. After installation, a test must be conducted first, and formal use can only be allowed after normal operation.
