Is the service life of different types of floating oil seals the same?

2020-09-08 15:50:23
Floating oil seal is a common mechanical seal. Due to the different cross-sectional shapes of the floating seal ring, floating oil seals can be divided into stepped, bell-mouthed, and wide spherical types. The performance characteristics of different types of floating oil seals are different. , Does this affect their service life? Is the service life of different types of floating oil seals the same?

Floating oil seals of different specifications and types have different effects and performance characteristics due to different shapes, and naturally different lengths of service life. For example, the stepped floating oil seal saves materials and labor, has good working surface lubrication performance and good heat dissipation effect, but the overall width of the working surface is narrow and the service life is limited. The cross-section of the bell-mouth floating oil seal is bell-shaped, and the sealing is completed by its bright band. Its advantages are similar to the stepped type, but the disadvantages are the same, but the difference is that the bell-mouth type floating oil seal is slightly wider than the stepped type, so the service life is relatively relatively. 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 longer, but the cost is higher than that of the step type and bell mouth.
