How to Diagnose Seal Failure and Solutions | Leak Diagnosis | Parker Hannifin

Описание: How to diagnose and provide solutions for various seal failure modes by Parker O-Ring & Engineered Seals Division Tech Webinar. Application Engineering experts discuss the different types of seal failure modes, what they look like, how to diagnose them, and solutions to prevent these failures.

There are many situations where an O-Ring may not last as long as one thinks that it should. When the expectation is realistic and yet the seal fails earlier than expected, the Applications Engineering team is often asked to help discover the failure mode(s).

Seal failures are often due to a combination of failure modes, making root cause difficult to uncover. When we begin a failure analysis, we will ask for: hardware information, how the seal is installed, application conditions (temp, fluids, and pressure exposure), and how long into the service that the seal failed. These details help bring the overall application into focus and enable us to quickly diagnose and resolve seal failures. In part one of our seal failure blog series, we will discuss the compression set, extrusion, and spiral failure.
