Correcting seal failures: Determining the cause of the problem and taking appropriate action will help your company's bottom line

摘要

In May we discussed why seals are vital to the maintenance of operating machinery. Unfortunately, seals can either wear out or Fail. To determine whether a seal has worn or Failed, the wearable Face should be examined. For most lip seals this is the Face manufactured From some type of elastomer (rubber). Since the seal Face is the only sacrificial part of a mechanical seal, a worn out seal has no elastomer nose piece left at the time it started to leak. A Failed seal still has substantial elastomer remaining at the time it started to leak.
