Generally speaking, the hydraulic paper cutter may have oil leakage after long-term use. Although the paper cutter can work normally when there is oil leakage, the oil consumption of the paper cutter increases the oil consumption. Is also a waste. For the printing of this problem, the factory user thinks that as long as it can be used, it is necessary to repair and a large fee, the project is not small, it is necessary to replace the hydraulic valve and other parts of the resin oil seal, skeleton oil seal, etc It can be solved, but after several replacements, the oil leakage problem of some hydraulic paper cutters still exists, and the expected leak stop effect has not been achieved.

        For this problem, the editor feels that we should pay attention to the quality of the replaced sealing ring, and the sealing ring with a long inventory time will also age and deteriorate, which will easily cause the machine to leak again and affect the sealing effect of the paper cutter. Maintenance is an important part of the hydraulic paper cutter in use. Many people ignore the maintenance link when using hydraulic paper cutters. Through the general inspection of hydraulic paper cutter parts, maintenance personnel can find and lock the parts that need to be repaired and replaced, and through the hydraulic paper cutter parts Debugging to ensure the running accuracy of the hydraulic paper cutter. Therefore, it is necessary to remind everyone here that when replacing the sealing ring of the paper cutter, it is best to pay attention to its quality and newness to avoid repeated oil leakage problems.
