MODULE DETAILS

Module 13: Mechanical Seals


Nominal duration: 2 weeks (24 hours total time commitment)


This time commitment includes the preparation reading, attendance at each webinar (1 hour plus 15-30 minutes for discussion), and the time necessary to complete the assignments and further study.

 

MODULE PURPOSE

 

 

Faced with the bewildering task of selecting the correct seal type and materials of construction for a given application, it's no wonder that many end-users leave the job to others. After studying this module, students will have the knowledge and confidence to select correct seal types, analyze failed seals, determine the cause/s of failure and propose practical, and take remedial action. Thus, with simple modifications, students can extend seal life and reduce or eliminate causes of premature seal failure.

The module commences with a solid review of the fundamentals and basic principles, and looks at seal classification and design. Special seal types are examined and the materials used to construct seals ranging from elastomeric materials to cemented carbides are examined.
