1.The inner rotary oil seal is actually a kind of structure type of rotary seal, which is generally composed of moving ring and static ring.
2.It is the use of the structure of the shape of the arrangement, so that the path of oil leakage elongated, as if into the "maze", and leakage of oil, because of the role of rotating centrifugal force, can return halfway and no longer leakage.
3.Due to less friction than the skeleton oil seal, and the higher the rotating speed, the better the sealing effect, it is often used in high-speed rotating occasions.
4. Speed = >Mechanical movement speed is high, the lubrication oil film may be destroyed, because of not good lubrication and friction heating oil seal, cause life is greatly reduced, we use polyurethane or rubber oil seal at 0.03 m/s ~ 0.8 m/s speed within the scope of work is good
5. The temperature= > Low temperature will lower the elasticity of polyurethane or rubber seal, cause leaks, and even the entire oil seal becomes hard and brittle. High temperature can make oil seal volume expansion, soft, cause movement oil seal friction resistance increase rapidly and reduce the compression capacity. Suggest polyurethane or rubber oil seal work continuously - 10 ℃ ~ + 80 ℃ temperature range.
6. Should= > Consider when pressure = "high pressure oil seal compression deformation, repellent extrusion ring, groove processing aspect also have special requirements. For get together ammoniac fat sealing the best working pressure in the range of 2.5 ~ 31.5 MPa.
7. Load=>Oil cylinder can bear larger load, seal and bearing ring in a completely different role, suggest polyurethane sealing ring to ensure that the cylinder can bear larger load
Requirements for protecting the main lip of the oil seal:
1. When the oil seal passes through the shaft with splines, keyways or holes, a bullet-type protective tooling shall be used.
2. The surface roughness Ra max of the bullet-type tooling does not exceed 3.2um, and no scratches or burrs are allowed.
3. The outer diameter of the oil seal and the main lip must be coated with a layer of lubricant.
4. Use uniform speed and pressure in the oil package to prevent the spring from falling off.
1. The installation of the oil seal can be flush with the front end of the casing aperture, or it can be close to the low section of the casing aperture.
2. The reference planes for installation and positioning should be machined surfaces, and the unprocessed reference planes cannot be used.
3. The outer diameter of the oil seal should be coated with a layer of lubricant.
4, using hydraulic or pneumatic uniform pressure compression oil seal.
Note: The matching surface of the oil package is flush with the reference surface of the housing to ensure the verticality of the shaft and the center of the shaft after the shaft is installed, so that the oil seal lip becomes a line contact belt on the shaft surface to achieve a good sealing effect.
