Open the box and check whether all parts of the fan are complete, whether there are bruises on the outside of the casing, especially pay attention to whether the head rectifier is bruised and deformed.
When the distance between moving and stationary blades increases, the influence of potential flow interference decreases much faster than that of wake velocity change.
Due to the large difference between temperature and grain temperature, the first ventilation time should be selected in the daytime to reduce the difference between grain temperature and temperature and reduce the occurrence of dew condensation.
The following classifications are made according to the characteristics of tube axial fans:Classification by material: steel fan, FRP fan, plastic fan, PP fan, PVC fan, magnesium alloy fan, aluminum fan, stainless steel fan, etc.
Tube axial fans are widely used, that is, the air flow in the same direction as the axis of the fan blade, such as electric fans, air conditioning external fans are tube axial fans.
PP centrifugal fan material properties and uses Polypropylene plastic centrifugal fan has the characteristics of high strength, light weight, good corrosion resistance, not easy to age, low noise, etc.
