Explosion-proof and anti-corrosion axial fans have a wide range of applications in the industrial field, and their design and manufacture need to take many factors into account to ensure that they can operate reliably in a variety of harsh environments. This article will introduce the characteristics, applications, design points and development trends of explosion-proof and anti-corrosion axial flow fans.
1. Characteristics of explosion-proof and anti-corrosion axial flow fans.
Explosion-proof and anti-corrosion axial flow fans are mainly used for ventilation and exhaust in harsh environments such as explosive, flammable, corrosive, etc. It has the following features:
1.Explosion-proof performance: Explosion-proof motor is used to ensure safe and reliable operation in explosive and flammable environments.
2.Anti-corrosion performance: made of anti-corrosion materials, it can operate stably for a long time in corrosive environments.
3.High reliability: The selection of high-quality components, after strict testing and inspection, to ensure that the wind turbine can operate reliably in a variety of harsh environments.
4.Low noise: Low noise design is adopted to reduce noise pollution to the surrounding environment.
5.Easy to maintain: simple structure, easy to disassemble and assemble, easy to daily maintenance and maintenance.
Second, the application of explosion-proof and anti-corrosion axial flow fan.
Explosion-proof and anti-corrosion axial flow fans are widely used in petroleum, chemical, pharmaceutical, light industry, metallurgy and other industrial sectors, mainly used in the following occasions:
1.Ventilation and exhaust of explosive, flammable gases and dusts.
2.Emission of corrosive gases such as acid mist and alkali mist.
3.Ventilation and exhaust in high-temperature, high-humidity environments.
4.Places where low noise is required.
3. Key points of the design of explosion-proof and anti-corrosion axial flow fans.
1.Impeller design: The impeller is the core component of the fan, and its design directly affects the performance of the fan. Explosion-proof and anti-corrosion axial flow fans usually use twisted airfoil blades, which have a high lift coefficient and a low drag coefficient, which can provide large ventilation and less noise. In addition, the strength and stiffness of the blades should be sufficient to prevent deformation and fracture during operation.
2.Housing design: The housing is another important part of the explosion-proof and anti-corrosion axial flow fan, which can protect the motor and impeller from the external environment. The shell is usually made of galvanized steel or stainless steel plate, which has good anti-corrosion properties and high mechanical strength. In addition, the enclosure is designed with ventilation and exhaust in mind to ensure a smooth flow of gases.
3.Motor design: The motor is the power of the fan, and its performance directly affects the reliability of the fan. Explosion-proof and anti-corrosion axial flow fans usually use explosion-proof motors, which have good explosion-proof performance and high efficiency. In addition, the motor should be able to withstand the effects of harsh environments and have good stability and reliability.
4.Transmission mode: Explosion-proof and anti-corrosion axial flow fans usually adopt two modes: direct transmission or belt wheel transmission. Direct transmission has the advantages of simple structure and convenient maintenance, but it requires high concentricity between the motor and the impeller. The pulley drive can reduce the alignment.
