How Should Contra-Rotating Axial Flow Main Fans Be Properly Stored Before Installation?

Proper storage of Contra-rotating Axial Flow Main Fans before installation is crucial to ensure their optimal performance and longevity. When receiving the cargo for delivery, all parts, including disassembled components like blades, accessories, spare parts, tools, standard parts, and measuring instruments, must be stored in a waterproof, sunproof, and theft-proof warehouse.

For larger parts, such as the collector, main unit, anechoic diffuser barrel, and anechoic diffuser tower, transportation can occur without packing. However, if warehouse space is limited, these components should be placed on a flat, elevated surface (at least 200mm high) to prevent water accumulation. It is important to cover them with waterproof cloth to shield them from environmental factors.

Special attention must be given to the motor, which should never be stored outdoors. It requires protective measures against moisture and water. Additionally, the motor’s unpainted outer surfaces and shaft extension end must be treated with anti-rust coatings to prevent corrosion during storage.

By following these guidelines, the Contra-rotating Axial Flow Main Fan components can be effectively preserved until they are ready for installation, ensuring their long-term reliability and performance.
