Answer: If you are not careful when replacing the oil seal of an air compressor, the replaced seal will still leak. Therefore, pay attention to the following matters to ensure the normal use of the replaced oil seal; The seal installation direction must not be wrong; Prevent foreign matter and dust from entering the seal and causing leakage during installation; Apply lubricating oil to the shaft diameter during assembly to avoid damage to the seal during installation; Scratches on the surface of the sealing sleeve cause leakage; The surface roughness of the sleeve is not appropriate; Use the original oil seal of the original manufacturer, as substitute oil seals are often prone to leakage; Check and confirm that there are no abnormalities in the shaft diameter and positioning bearing before replacement.
