Hydraulic oil seal product introduction:

The hydraulic oil seal is a kind of hydraulic oil seal. This oil seal is more sealed than the hydraulic oil seal. The hydraulic oil seal is round, and the industry has become an O-type hydraulic oil seal.

Sealing principle of hydraulic oil seal ring:

Sealing principle: Because there is a filter cylinder with a skeleton seal tooth surface manipulation in the middle of the skeleton seal and the shaft, the filter cartridge has the characteristics of two-phase flow lubrication. Under the effect of surface tension coefficient, the strength of the filter cartridge happens to produce a crescent moon at the touch end of the filter cartridge and the gas, avoiding the leakage of the business medium, thereby achieving the sealing of the arc. The sealing potential of the skeleton seal depends on the thickness of the protruding filter cartridge, the thickness is too large, and the skeleton seal is leaked; if the thickness is too small, dry friction will occur, causing skeleton seal and shaft damage; there is no filter between the seal lip and the shaft. The tube is easy to cause hot and damaged.


For this reason, when installing, be sure to apply some oil on the seal ring to ensure that the skeleton seal and the roller axis are vertical. If it is not vertical, the seal lip of the skeleton seal will drain the grease from the shaft, which will also cause Excessive wear of the sealed lip. During operation, the lubricating fluid emblem inside the casing is extravasated, which is better than the case where the filter cartridge is produced at the protruding surface.


The above is the product introduction of the hydraulic oil seal ring summarized by Xiaobian for you. I hope everyone can have a better understanding of the hydraulic oil seal through this article.
