Failure Analysis (A8101)
About this class
Learn the steps necessary to prepare to remove, and to remove, a failed mechanical seal. The lesson trains the participant in failure analysis to determine the cause of seal failure and identify the means to correct the problem or condition that caused the failure.
Prerequisites
Knowledge of mechanical seal components and design.
Description
This is the third lesson in the iKNOW® Mechanical Seals Library. This lesson demonstrates the steps necessary to prepare to remove, and to remove, a failed mechanical seal. The lesson trains the participant in failure analysis to determine the cause of seal failure and identify the means to correct the problem or condition that caused the failure.
Objectives
List the steps necessary to prepare for removing a failed mechanical seal. List the steps to removing a failed mechanical seal. Perform a failure analysis to determine the cause of seal failure. Identify the means to correct the problem or condition that caused seal failure. List the steps to follow to properly analyze seal failure. Describe seal damage caused by chemical attack. Describe seal damage caused by heat. Describe seal damage caused by mechanical action.

Bearings - Failure Analysis (A8101)
This lesson explains the purpose of bearings and demonstrates how
bearings reduce friction and maintain the alignment of operating
equipment. The basic operation of anti-friction bearings and plain
journal bearings is demonstrated as well as the importance of full fluid
film lubrication and proper lubrication clearance. Additionally,
indications of various premature bearing failures are discussed.
