There will be a carburized structure on the surface of the floating oil seal ring, so the choice of heating temperature is an important issue. The heated oil seal ring will produce uniform austenite, which improves the wear resistance, followed by the grinding stone on the surface of the oil seal ring. In order to increase precision and finish. Scratches and polishing will affect the life of the oil seal ring. Therefore, selecting the correct and appropriate material for the surface treatment of the oil seal ring can effectively ensure the service life of the oil seal ring.

After the hot oil pump is stopped, the cooling cannot be stopped immediately, especially the cooling water in the oil seal cavity and the end face seal should be kept for a period of time, and the cooling should be stopped until the temperature gradually drops below 80 degrees Celsius, otherwise it will Cause damage to the sealing parts.

For the maintenance of the oil seal of the excavator, we need to clean it every day, and clean the oil tank to check whether there is oil leakage. If this happens, it indicates that there is a problem with the sealing performance of the oil seal, and it needs to be solved in time. , So as not to cause the excavator to not work normally, there is also an inspection of each component.
