High-temperature fanThe manufacturer believes that the centrifugal fan casing has characteristics such as energy saving, stable operation, low noise, and simple maintenance. It is specially designed for air supply and exhaust equipment under different operating conditions to adjust the required air volume according to seasonal changes and operating conditions. The centrifugal fan casing is generally used for air supply and exhaust in air conditioning engineering systems in industries such as industrial production, civil buildings, commercial entertainment, and education and health.

　　The high-temperature fan manufacturer believes that the design of the centrifugal fan casing includes some shock absorbers, so the vibration amplitude of the casing is relatively small, and the noise reduction effect is good. The new centrifugal fan casing is small in size, light in weight, and convenient for transportation, movement, installation, and disassembly. The centrifugal fan shell has a wide range of applications. It can be used for ventilation and smoke exhaust in places such as high-end hotels, high-end restaurants, basements, and office buildings. Especially in some high-end living places, the specifications of the centrifugal fan casing are complete, and the craftsmanship is novel, which can meet the needs of people's production and life.

　　The high-temperature fan manufacturer believes that the shell of the centrifugal fan casing is specially designed to greatly reduce outgoing noise. Under the conditions of unit air volume and unit air pressure, the sound level is reduced by 2-3 dB(A), and at lower speed conditions, higher fan pressure can be obtained. In the air supply and exhaust systems of industrial and mining enterprises and high-end civil buildings without a large number of soundproofing measures, cabinet centrifugal fan casings can replace low-pressure centrifugal fans or high-pressure axial flow fans. When the centrifugal fan casing is used to discharge high-temperature flue gas or air from a centrifugal boiler's induced draft fan, a valve for starting should be set to prevent motor overload during cold operation. The connection between the ventilator's inlet and outlet and the air duct should have flexible joints. The inlet and outlet ducts should be supported separately and firmly supported by the building's foundation or other components, and the casing should not bear the weight of other parts.

　　High-temperature fanThe manufacturer believes that centrifugal fans should be selected based on the following reference indicators:

　　1. Whether the fan's performance can meet the standard air pressure and air volume; only fans that meet the standards can satisfy the required air volume for production.

　　2. The working efficiency of the fan. The standard for selection is to prioritize fans that can maintain high efficiency under low power consumption conditions.

　　3. Whether the matching mechanisms of various parts of the fan strictly adhere to national standards; first, select the matching of bearings and shafts, and the matching of holes and shafts; the lower the vibration value, the longer the fan's service life.

　　4. The high-temperature fan manufacturer believes that the working performance of the machine during operation is mainly reflected in the vibration value and noise level. Fan noise is environmental pollution. If the noise reaches a certain level, it will affect employees' work emotions and reduce work efficiency.

　　5. Consider the convenience of maintenance when selecting. Fans are electrical devices that require regular maintenance. Generally, there should be convenient oil filling holes and maintenance oil drainage holes, and the bearings should be easy to disassemble and assemble.

　　6. The high-temperature fan manufacturer believes that the quality can be seen from the appearance; attention should be paid to details during observation. In addition, when buying fans, it is generally advisable to choose manufacturers with a good market reputation, long operating time, large sales volume, and large scale.
