Most mechanical seal failures come from operation and installation rather than manufacturing defects. Early detection of abnormal signs helps avoid breakdowns and unplanned machine stops. This article summarizes warning signs and maintenance practices to extend the life of seals.
A small amount of moisture during the run-in period is normal. Continuously increasing leaks, dripping, or accompanied by noise are signs that require checking. For hazardous media, all leaks must be handled immediately.
Schedule regular inspections for auxiliary systems, tanks, and pipes, check the level and pressure of barrier fluids, replace filter cores, and check gaskets according to the manufacturer's recommendations.
Keep seals in their original packaging, in a dry, cool place, away from sunlight and chemicals. Rubber gaskets have a shelf life, so inventory needs to be rotated.
Record the life of each seal, failure cause, and cost. Indicators such as the average time between failures help evaluate effectiveness and guide upgrades. Contact SNS-VN if technical support is needed.
