Huadong Fan teaches you how to deal with oil leakage from the return fan of industrial boiler fans
Return fan
Find out the cause of the problem:
Before dealing with the problem, you must first know the cause of the problem, so to solve the oil leakage problem You must first find the reason. Based on long-term production and use experience, we have summarized the following reasons:
Friction between impeller and impeller: contamination and impurities on the impeller cause excessive clearance. Impeller wear is not firm. Impeller is not firmly fixed and cannot maintain impeller synchronization. Bearing wear causes increased clearance. .
Solution to the return fan
These situations may cause oil leakage. The solution is: remove the dirt and check whether the internal parts are damaged. Adjust the gear backlash. If the gear backlash is greater than % to % of the average value, the gear should be replaced. Or replace the bearing directly. In addition to the impeller, failure of parts of the machine body can also cause oil leakage, such as incorrect installation clearance, excessive operating pressure, deformation of the casing or base, and poor axial positioning of the bearings. The solution is: readjust the gap, find out the cause of overload, reduce the pressure to the specified value, check the installation accuracy, reduce the tension of the pipeline, check and repair the bearing to ensure the clearance.
