Inspection and replacement of floating seal wear

As a highly adaptive mechanical seal, floating sealing can adapt to various harsh working environments and is widely used for various mechanical equipment. If severe wear or leakage occurs, it will directly affect the normal operation of the equipment and even affect the service life of the equipment. If the floating oil seal is worn, it needs to be checked and replaced in time. So, to what extent should the floating oil seal be replaced?

Inspection and replacement of floating seal wear

Generally, during the wear process, the floating seal of the casting can automatically compensate for the wear, and the floating seal interface (the contact strip with a width of about 0.2mm to 0.5mm is used to keep the oil lubricated and prevent external dirt from entering) will continue to update automatically, adding a little wide and gradually moves toward the inner hole of the floating seal ring. By checking the location of the seal band based on the stalk, the life and wear of the remaining sealing rings can be estimated.

When the bearing and sealing rings are usually grinding, according to the degree of wear, the oil -resistant rubber ring with a thickness of 2 to 4 mm can be filled between the sealing sleeve and the end surface of the wheels. After installation, the cover component should rotate freely on the hub. In addition, a washer with an outer diameter of 100mm, an inner diameter of 85mm, and a thickness of 1.5mm can be used to compensate for the amount of bearing wear between the bearing outer ring and the sealing housing support shoulder. When the height is less than 32 mm and the bearing width is less than 41 mm, new products should be replaced.
