High-temperature fans are a major category of fans.High-temperature fanGenerally refers to high-temperature centrifugal fans used as induced fans. Due to the special conditions of use, separate standards and performance parameters are determined. The following analysis is a simple overview of high-temperature fans based on their classification and structure.

　　What are the classification characteristics of high-temperature fans?

　　1. Classified by medium temperature, there are generally 250 ~ 400 degrees, 400 ~ 500 degrees, 500 ~ 800 degrees, and above 800 degrees. Depending on the medium temperature and the type of blower, heat-resistant stainless steel or alloy steel is used.

　　2. According to the pressure level, they are usually divided into medium-low pressure high-temperature fans and high-pressure high-temperature fans.

　　3. Classified by structure, they are divided into cased and non-cased high-temperature fans.High-temperature fan4. Classified by working mode, they are divided into fixed frequency high-temperature fans and variable frequency high-temperature fans.

　　What are the structural characteristics of high-temperature fans?

　　High-temperature fans are currently widely used in various kiln industries, and the future development prospects are optimistic, mainly in the following aspects:

　　First, with the popularization of energy-saving motors and the elimination of outdated motors, high-temperature fans will have higher efficiency, and the widespread application of inverters will make the energy-saving effects of fans more apparent, resulting in lower long-term operating costs.

　　Secondly, with the development of new technologies and high-temperature resistant technologies, high-temperature fans will not only withstand high temperatures but also have anti-corrosion functions and characteristics.

　　In the future, there will be more industry and commercial applications, and high-temperature fans will also contribute to improving productivity, providing more optimized solutions for auxiliary machines.

　　High-temperature fanWhat is the structure of high-temperature fans?

　　1. High-temperature fans are mainly composed of an impeller, casing, inlet, motor, connector, and cooling fan blades.

　　2. The impeller is made of high-quality galvanized or cold-rolled steel plates and has multiple air intake centrifugal blades. The blades are designed based on aerodynamics. The high-temperature blower impeller consists of 10 types of blades, made up of front and rear edge curved blades. The material is made of high-quality steel plates, ensuring high strength. It is durable and undergoes strict dynamic balance correction. The air quality is good, efficiency is high, and operation is stable.

　　3. The shape of the inlet is a converging circular flow, which minimizes air loss and allows the fan to operate effectively.

　　4. The casing of the high-temperature fan and the motor are connected by metal castings, and the cooling fan blades are mounted on the motor shaft. The inlet and outlet pipe interfaces are installed on the outer wall of the metal casting to cool the metal casting and bearings, allowing the motor to operate normally at high temperatures.

　　5. The motor uses a dedicated high-temperature motor, and some high-temperature fan liquids use heat-resistant materials. The cooling structure is reliable, and compared to other boiler fans, the structure is simple, maintenance is convenient, and costs are high.

　　6. Small industrial fans have a lightweight structure, attractive appearance, low noise, and high static pressure. They can be used for ventilation in small spaces, jet pressure, thermal circulation systems, and high-temperature gas supply (above 200 degrees). They can also use heat-resistant fans, anti-corrosion equipment, air conditioning, and other materials such as stainless steel, polypropylene cleaning equipment, and ordinary A3 sprayers.
