Corrosion-resistant high-pressure fans have several special requirements regarding materials. First, the outer casing is typically made of stainless steel with excellent corrosion resistance, such as 304 or 316 stainless steel, effectively resisting various chemical corrosions and extending the fan's service life.
The impeller material is also crucial, generally using aluminum alloy or carbon steel with a special anti-corrosion coating. Aluminum alloy is lightweight, high-strength, and has good corrosion resistance; carbon steel with a special anti-corrosion coating enhances its surface corrosion resistance, ensuring normal operation in harsh environments.
The fan shaft is usually made of stainless steel or alloy steel with a special surface treatment to prevent rusting in humid and corrosive environments, ensuring the stability and reliability of the transmission.
The seals must be made of chemically corrosion-resistant rubber materials to ensure effective isolation between the fan's interior and the external environment, preventing the leakage or entry of corrosive gases, which could affect its performance and lifespan.
Furthermore, connecting components should also be made of materials with good corrosion resistance, such as stainless steel bolts and nuts, ensuring the overall structural stability and corrosion resistance of the fan, thus meeting the needs of various corrosion-resistant working conditions.
