From a normal perspective, after a long period of use, the paper cutting machine may basically leak oil. Although the paper cutting machine can work normally when there is an oil leakage fault, the oil leakage from the paper cutting machine will increase the fuel consumption. Large, causing waste.

         The maintenance of oil leakage of the paper cutter needs to replace the skeleton oil seals and resin oil seals of several other parts, such as valves. After the replacement, the oil leakage problem can be solved. However, after the replacement of many users, the oil leakage phenomenon of the paper cutter still exists and did not achieve the expected solution. This is mainly because the quality of the replacement seals is not up to standard. It is because the storage time is too long, which causes deterioration and aging. Therefore, the replacement of these seals can easily cause the paper cutter to leak again, which affects the sealing effect of the paper cutter. Therefore, the quality of the sealing ring should be paid attention to when replacing its sealing ring, so as to prevent the problem of oil leakage from appearing repeatedly.
