Installation and use of rubber sealing rings should pay attention to:
(1) Prevent overdue use. The service life of the rubber seal of the dynamic seal is generally 3000-5000h, and the new sealing ring should be replaced in time.
2) Avoid using old seals. When using a new sealing ring, it is also necessary to carefully check its surface quality to ensure that there are no defects such as small holes, protrusions, cracks and grooves, and that it has sufficient elasticity before use.
(3) When replacing the sealing ring, the groove of the sealing ring should be strictly checked, the dirt should be removed, and the bottom of the groove should be polished.
(4) Do not install in the wrong direction and damage the lip. If there are scars of more than 50μm on the lip, it may cause obvious oil leakage.
(5) Prevent forced installation. Can not be knocked in with a hammer, but use a special tool to press the sealing ring into the seat hole, and then use a simple cylinder to protect the lip through the spline. Before installation, apply some lubricating oil to the lips to facilitate installation and prevent burns during initial operation. Pay attention to cleaning.
(6) The size of the replacement sealing ring should be the same. It is necessary to strictly follow the requirements of the manual and select the same size sealing ring, otherwise the requirements such as compaction cannot be guaranteed.
(7) When installing, all parts of the opened hydraulic system should be cleaned strictly first, and it is best to use special tools to prevent the sharp edges of the metal from scratching the fingers.
(8) In order to prevent oil leakage caused by damage, it must be operated in accordance with the regulations, and at the same time, the machine cannot be overloaded for a long time or run in a relatively harsh environment.
