800 tonsfour-column hydraulic pressMost of the oil leakage is caused by the failure of the sealing ring, because the sealing ring plays a sealing role with elastic pressure. If the elastic pressure disappears slowly after long-term use, the sealing effect will naturally decrease until there is no sealing effect. In this case, it is possible to replace the sealing ring, but it should be noted that the sealing ring of the same size must be selected in strict accordance with the instructions, otherwise it cannot guarantee its proper compression and other requirements.
However, the failure of the sealing ring is not the only reason for the oil leakage of the 800-ton four-column hydraulic press, so the specific problem must be analyzed in detail, so as to find out the key to the problem and take appropriate measures to solve it.
