High-temperature fans are a type of special fan designed for high-temperature working environments, made from materials that are highly resistant to high temperatures and high pressure. High-temperature fans mainly include: stainless steel resistant, transmission, centrifugal types, etc. They are widely used in fields such as chemical industry, petroleum, metallurgy, forging, electricity, nuclear power plants, and environmental protection.
High-temperature fanIt belongs to special fans, specifically designed for high-temperature working environments, with materials that have strong high-temperature and high-pressure resistance. High-temperature fans mainly include: stainless steel, transmission, centrifugal types, etc. They are widely used in chemical industry, petroleum, metallurgy, forging, electricity, nuclear power plants, environmental protection, and other fields.
I. Structural characteristics of high-temperature fans
1. Mainly composed of impeller, casing, air inlet, motor, connector, cooling fan blades, etc.
2. The impeller uses a multi-blade single-inlet centrifugal impeller made of high-quality galvanized sheet or cold-rolled steel plate, with blades designed based on aerodynamic principles. The impeller consists of 10 backward-inclined airfoil blades, a curved front disc, and a flat rear disc. Made of high-quality steel plate, it has high material strength, good durability, and has undergone strict dynamic and static balance correction. It has good air performance, high efficiency, and stable operation.
3. The air inlet adopts a converging streamlined vortex reduction form, resulting in low airflow loss,High-temperature fanand high working efficiency.
4. The casing of the high-temperature fan is connected to the motor through metal casting, and the motor's shaft head is equipped with heat dissipation blades. The outer wall of the metal casting has water inlet and outlet pipe interfaces to cool the metal casting and shaft head, ensuring the motor operates normally at high temperatures.
5. Its motor is a special high-temperature motor, and the fluid part of the high-temperature fan is made of heat-resistant materials, with reliable cooling structure performance. Compared to other boiler induced draft fans, it has advantages such as simple structure, convenient maintenance, and high cost-effectiveness.
II. Safety measures for high-temperature fans:
1. Fixed measures are needed during installation to ensure safety and prevent accidents from falling in strong winds.
2. The addition of anti-aging agent materials is necessary to extend the service life of the high-temperature fan.
3. Reliable rain and snow protection measures are required during the installation of high-temperature fans.
4. Using stainless steel can greatly enhance the pressure resistance and corrosion resistance of high-temperature fans.
5. Bird nets are needed to prevent birds from entering.
Therefore, to ensureHigh-temperature fanthe quality of work and safety during the operation process, protective measures must be well implemented.
III. Characteristics of high-temperature fans:
High-temperature fans can be used for blowing or suction, and can be used as a single machine.
If operated with little or no oil, the air delivered by the high-temperature fan is relatively clean. When the pump body of the high-temperature fan is entirely die-cast and uses a shock-absorbing device for the base, its requirements for the installation foundation are also very low, allowing normal operation without a flowing base, making it extremely convenient and economical in terms of installation use and cycle.
The wear on the fan machine is significant, as it uses bearings. During the warranty period, there are only two bearings as consumables, requiring minimal maintenance. For fans of the same type, high-temperature fans produce very low noise.
