Correct Installation Method Of Skeleton Oil Seal Ring

1. From the skeleton oil seal ring to assembly, it must be kept clean, and do not tear the wrapping paper prematurely to prevent debris from adhering to the surface of the skeleton oil seal ring and being brought into the working part.

2. Before assembling the skeleton oil seal sealing ring, do the machining inspection procedure, and check whether the size of each part of the skeleton oil seal sealing ring is consistent with the size of the shaft and the cavity. The end faces of the shaft and the cavity should be smooth and clean, and the chamfers should be free of damage and burrs, and the assembly parts must be cleaned. The shaft and seat hole should be processed with a chamfer of 15-30°, especially the inner chamfer, and there should be no slope. It is recommended to use a rounded chamfer for the assembly part of the skeleton oil seal. There should be no burrs, sand, iron filings and other debris in the shaft installation (chamfer) to prevent accidental damage to the sealing lip of the skeleton oil seal seal. The size of the cavity should be compatible with the outer diameter and width of the skeleton oil seal.

3. Check whether the lip of the skeleton oil seal seal is complete, check whether the lip of the skeleton oil seal seal is damaged or deformed, and whether the spring of the skeleton oil seal seal has fallen off or rusted, so as to prevent the skeleton oil seal seal from being subjected to external force during transportation. The roundness is destroyed by the influence of extrusion and impact.

4. If the skeleton oil seal has an oil return line, first determine the relationship between the installation direction and the rotation direction of the skeleton oil seal.

5. When assembling the skeleton oil seal sealing ring, an appropriate amount of cleaning ointment such as lithium base ester added with molybdenum disulfide should be applied between the lips of the skeleton oil seal seal to prevent the shaft from causing damage to the lip of the skeleton oil seal seal when the shaft starts instantaneously. The dry grinding phenomenon affects the interference of the lip of the skeleton oil seal seal, and the surface of the contact part of the lip of the skeleton oil seal seal should not be processed with thread marks. When assembling, apply sealant to the outer ring of the skeleton oil seal, wrap the keyway or step on the shaft with hard paper, etc. to avoid scratching or rolling the lip of the skeleton oil seal, or use special tools such as guide transition sleeves. The skeleton oil seal seal is rotated and pressed inward, and it is absolutely not allowed to smash hard to prevent the skeleton of the skeleton oil seal seal from deforming or breaking the spring of the skeleton oil seal seal and failing. If the sealing lip of the skeleton oil seal seal ring is flanged, the spring falls off and the skeleton oil seal seal circle is skewed, remove the skeleton oil seal seal and re-install it.

6. Use special installation tools correctly to protect the sealing lip of the skeleton oil seal seal from damage to the cup. Even slight scratches are not allowed, otherwise it will easily cause the skeleton oil seal seal to leak. It is recommended to use hydraulic equipment or sleeve tools for installation, the pressure should not be too high, and the speed should be uniform.

7. When the skeleton oil seal sealing circle is loaded into the shell, it should be carried out with uniform pressure and should not be tilted to avoid deformation of the outer circle of the skeleton oil seal sealing ring.

8. When installing the skeleton oil seal, pay attention to the installation method. When inner sealing is required, the side of the skeleton oil seal with the self-tightening spring faces the inside of the box to prevent the lip from going outward.

The correct installation of the skeleton oil seal seal is an important link that leads to the longevity of the skeleton oil seal seal.
