Xinfeng Mini-Class: What Are the Structural Differences of Stainless Steel Fans?

Stainless steel fans are widely used in industrial production. Due to their distinct characteristics, different regions impose varying requirements on stainless steel fans for specific applications.

For instance, under high corrosion resistance requirements, stainless steel fans must be used when casing fans fail to meet standards. These fans are designed and manufactured for petrochemical and mechanical equipment where harmful gases pose severe corrosion risks to ordinary steel.

Compared to conventional fans, stainless steel models not only meet ventilation requirements but also significantly extend equipment lifespan. For users, these units can handle acidic/alkaline corrosive vapors and transport high-temperature steam below 500°C. When constructed with premium titanium steel, they can withstand temperatures exceeding 800°C.

Due to their outstanding characteristics, stainless steel fans are widely used in industries such as chemical plants, metallurgy, carbon black production, and ceramics. They serve as ideal equipment for conveying organic exhaust gases from kiln tails, transferring equipment temperatures, and ignition processes. Key components of this equipment include the centrifugal impeller, casing, air duct, transmission system components, and base.

The centrifugal impeller is the core component of stainless steel fans. When designing its structure, it is crucial to base the design on the new fundamental theories of high-efficiency fans and select appropriate materials according to different load requirements.

It possesses reliable corrosion resistance and heat resistance. After manufacturing the centrifugal impeller, performance adjustments are made based on static data and dynamic balancing. This meets G5.6 standards (exceeding the national industry standard G6.3).

Secondly, the casing and base are critical components of stainless steel fans. Typically, the casing is fabricated from materials suited to specific operating conditions, ensuring reliable corrosion and heat resistance. It is welded to the overall structure to guarantee structural rigidity.

Additionally, in stainless steel fans, the inlet adopts high-quality stainless steel plates with a streamlined tapered structure secured by anchor bolts. The core components of the stainless steel fan transmission system include the main shaft bearing, rolling bearings, bearing housing, and coupling assembly. The main shaft bearing is crafted from premium high-temperature-resistant materials and undergoes quenching treatment to ensure sufficient compressive strength.
