In addition to the general requirements for sealing ring materials, sealing rings should also pay attention to the following conditions:
(1) Elastic and resilient;
(2) Appropriate mechanical strength, including expansion strength, elongation and tear resistance, etc.
(3) Stable performance, not easy to swell in the medium, and small thermal shrinkage effect (Joule effect).
(4) Easy to process and shape, and can maintain precise dimensions.
(5) It does not corrode the contact surface and does not pollute the medium, etc.
The most suitable and most commonly used material to meet the above requirements is rubber, so sealing rings are mostly made of rubber materials. There are many varieties of rubber, and new rubber varieties are constantly emerging. When designing and selecting, you should understand the characteristics of various rubbers and make reasonable choices.
Things to note when installing and using sealing rings:
(1) Do not install it in the wrong direction or damage the lip. If there are scars above 50μm on the lip, it may cause obvious oil leakage.
(2) Prevent forced installation. You cannot knock it in with a hammer, but use a special tool to press the sealing ring into the seat hole first, and then use a simple cylinder to protect the lip where it passes through the spline. Before installation, apply some lubricating oil on the lips to facilitate installation and prevent burns during initial operation. Pay attention to cleanliness.
(3) Prevent extended use. The service life of dynamic seal rubber seals is generally 3000 to 5000 hours, and new seals should be replaced in time.
(4) The size of the replacement seal ring must be consistent. Strictly follow the instructions and select sealing rings of the same size, otherwise the tightness and other requirements cannot be guaranteed.
(5) Avoid using old sealing rings. When using a new sealing ring, you should also carefully check its surface quality to make sure there are no defects such as holes, protrusions, cracks and grooves and that it has sufficient elasticity before use.
(6) During installation, all parts of the opened hydraulic system should be strictly cleaned first. It is best to use special tools to prevent fingers from being scratched by sharp metal edges.
(7) When replacing the sealing ring, strictly check the sealing ring groove, remove dirt, and polish the bottom of the groove.
(8) In order to prevent damage and oil leakage, the operation must be carried out according to the regulations. At the same time, the machine must not be overloaded for a long time or run in a relatively harsh environment.

1. Clean the installation location;
2. Remove burrs during the installation movement of the seal;
3. Apply lubricant to the seal;
4. Protect the sealing surface from damage;
5. Check to confirm that the size of the seal is correct;
6. Use corresponding tools to install seals that require deformation.
