【Seeking expert advice】What is the function of the plastic disc on the air-cooled fan?
Thread Content
There is a plastic disc at the top of the air-cooling fan in Ha Air Conditioner Factory. What is its specific function? One possibility is to prevent rain from getting in, but does it also serve to balance the rotating components? ? ?
It serves a waterproofing function, preventing rainwater from entering the bearing components. It has no other function.
It serves to increase the wheel hub ratio and improve airflow, as well as providing rain protection
The area above the air-cooled tube bundle does not need to be protected from rain; we use the same type of air cooler for air conditioning, and it doesn’t have any plastic discs. Where are these plastic discs that the original poster is talking about? Above the fan or above the tube bundle? Could you upload a photo to take a look?
It is located above the fan, fixed to the rotor, and rotates together with the rotor. Thank you to my colleagues for their guidance:handshake :handshake
