The frame structure of the
metal fan grille plays a vital role in its design. It not only supports the entire grille, but also affects the stability, safety and reliability of the grille.
Material selection:
The frame of the metal fan grille is usually made of metal materials to ensure sufficient strength and durability. Commonly used materials include steel, aluminum alloys and stainless steel. Each material has different properties and is suitable for different application environments:
Steel: Steel is a common choice, popular for its high strength and durability. It is suitable for use in industrial environments requiring greater safety and protection.
Aluminum alloy: Aluminum alloy is lighter and has better corrosion resistance. Suitable for use in indoor and outdoor ventilation systems, they are popular for their lightweight performance and corrosion resistance.
Stainless steel: Stainless steel is a metal material with excellent corrosion resistance and is often used in seaside areas or chemical plants where corrosion resistance is required.
Structural design:
The frame structure of the metal fan guard is usually solidly designed to ensure its stability and durability. Structural design should consider the following factors:
Connection method: The frame is usually connected to the front of the fan by welding, screws, nuts, etc. The connection must be secure so that the grille does not loosen or move while the fan is running. Welding is typically used for larger frames, while screw connections are typically used for smaller frames.
Support Structure: The support structure of the frame can be a single ring or multiple beams for added stability. The design of the support structure depends on the size and weight of the grille. Large grilles typically require more beams to support the entire structure.
Strength distribution: The design of a frame structure needs to consider the distribution of strength to ensure balanced support throughout the frame. This involves material selection, connection methods and the proper design of supporting structures.
