Different characteristics of different types of floating seal rings

2019-09-20 09:25:21
The floating seal ring is suitable for common sealing work under severe conditions such as high speed, high pressure, explosion proof, anti-virus and strong corrosion. The floating seal ring has a simple structure and good sealing performance. The possibility of the floating ring sliding on the end face ensures free positioning and prevents surface contact and wear during operation. In order to keep the thickness of the liquid film stable, it is necessary to provide an external oil source to supply the oil sealing system in order to seal the gas.


There are many types of floating seal rings. Different types of floating oil seals have different effects due to different shapes and different performance characteristics. The life limit is naturally different. For example, the stepped floating oil seal saves labor and labor, has good lubrication performance on the working surface, and has good heat dissipation effect, but the total width of the working surface is narrow and the service life is limited. The cross section of the flared oil seal has a flared shape, and the seal is completed by its bright band. Its advantages are similar to those of the step type, and the disadvantages are the same, but the difference is that the flared floating oil seal is slightly wider than the step type, so the service life is relatively Be longer. The advantage of the wide spherical oil seal is that the total width of the working surface is large and the service life is long, but the cost is higher than that of the step type and the bell mouth.
