The function of a diesel generator set fan is to increase the flow rate of air passing through the core of the radiator, improve the heat dissipation capacity of the radiator. Diesel generator set fans generally have the characteristics of large air volume, good cooling effect, and low noise. Depending on the type and rated power of the diesel generator set, different specifications of fans can be used. The fan has two structures: suction type and blowing type. Users can choose one according to their needs when ordering.
When the diesel generator set is working, the principle of whether the fan is a blowing or suction type is determined based on its rotation direction and the concave arc surface of the fan blade should be the pressure air surface. For example, when looking at the front end of a diesel engine, if the pressure surface (concave arc surface) of the fan faces you, it is a blowing type; On the contrary, when the non pressure surface (convex curved surface) faces you, it is a suction type. Do not install the fan upside down, otherwise the non pressure air surface of the fan blades will become the pressure air surface, affecting the fan airflow and reducing the heat dissipation effect of the radiator.
