1. The problems such as filter element and melt of FRP fan, uneven oil pipeline, pollution of oil cooler and abnormal operation of oil ring bearing are analyzed. Air parts and piping systems need to be replaced and cleaned regularly, and it is necessary to observe the operation status of oil ring bearings.

2. another important reason is oil deterioration, easy to lead to FRP fan overheating. Before changing oil, carefully check its quality, such as oxidation, viscosity, viscosity change index, dirt impact index, etc.

Through the above introduction, I believe you have a general understanding of the important causes of overheating in FRP fans. As long as we usually do maintenance and inspection, we can reduce the occurrence of fan problems.
