1. Overview
Compared with the DZ series axial flow fan, this series of axial flow fans has obvious advantages, such as more reasonable structure, more reasonable wheel hub design, reducing flow losses, high strength at the root of the blade. There is a significant improvement in performance that the total pressure efficiency is 89.5%, and the noise is reduced by 3.6dB (A). There are thirteen specifications for the impeller diameter of this series of fans, ranging from small to large. Each specification has four blades and five blade angles: 15°, 20°, 25°, 30°, and 35°. The parameter range is wide.
2. Quality level
This series of ventilation fans adopts the design method of starting from the sound source, low speed, and high pressure coefficient, and has been developed into a wide blade, large chord length, space distortion, and inclined blade type, which can achieve the required air volume and pressure under low-speed driving. It has the characteristics of high efficiency, low noise, low energy consumption, and smooth operation. This series of fans is suitable for transporting non flammable, explosive, non corrosive, and non significant dust gases. The ambient temperature should not exceed 60℃ (it can also be made into explosion-proof or anti-corrosion types according to customer requirements for use in explosion-proof or anti-corrosion places). It is widely used in factories, warehouses, offices, and residential areas for ventilation or strong heating heat dissipation. It can also be installed in series at intervals in longer exhaust pipes to increase the pressure in the pipes. Highly praised after extensive user experience and expert evaluation. The FT35 anti-corrosion axial flow fan is made of anti-corrosion material coated with epoxy deep processing surface, and the motor adopts a special anti-corrosion motor for conveying corrosive gases. The BT35 explosion-proof axial fan is also a derivative product of T35, used for conveying flammable and explosive gases. The impeller is made of aluminum alloy to prevent sparks during operation, and the motor is equipped with an explosion-proof motor. The performance parameters, external dimensions, and precautions of FT35 and BT35 fans are the same as those of T35 fan.
3. Structural features
This series of fans consists of main components such as impeller, casing, and motor. The impeller is connected to the motor, and the impeller rotates in the left direction (when viewed from the motor side).
4. Manufacturing process
a. Impeller: The blades are cut and molded by cold stamping, and the hub is stretched from Q235 steel plate and verified by a double-sided hard support dynamic balancing machine at high speed, with a balancing accuracy of G3.2 or above.
b. Inner cylinder: Round by a three core plate rolling machine, flanged by a spinning machine for one-time molding, with sufficient rigidity and beautiful appearance.
c. Chassis: All are cut by plasma cutting.
5. Parameter Range
The air volume range is 826~67892m³/h, and the total pressure range is 39~483Pa./h, and the total pressure range is 39~483Pa./h, and the total pressure range is 39~483Pa.
