HI / FSA 4-Part Mechanical Seals Webinar Series

“Introduction to Mechanical Seals” will be held on March 10, 12, 17, and 19, 2015

This 4-part webinar series is based on the Hydraulic Institute guidebook, Mechanical Seals for Pumps: Application Guidelines which was published in cooperation with the Fluid Sealing Association. Each webinar will last approximately 1 hour, including Q&A. Audio broadcast will be via your computer speakers or teleconference bridge.

The 4-Part Series includes:

Section 1: Mechanical Seals – Types and Operating Principles

March 10: 1:00-2:00PM ET
Section 1 explains how a mechanical seal works and gives an overview of the most common seal types. The objectives are to give the student a good understanding of how leakage, friction and wear of the materials interact and why many different seal types are used in pumps, agitators and compressors.

Section2: Mechanical Seals Construction and Design

March 12: 1:00-2:00PM ET
Topics discussed:

Explain different design features used in common seals
Strengths and weaknesses of various design options
Impact of design features on seal performance
Discuss seal faces, springs, and seal glands
Explain differences in seal chamber designs for common pumps

Section 3: Installation – Connections – Commissioning

March 17: 1:00-2:00PM ET
A mechanical seal, although designed for various applications at times, requires equipment prepared so that the life cycle is maximized. In this module we also examine seal supports systems that further promote longer seal life. Other topics include:

General knowledge of mechanical seals used in rotary equipment.
Basic preparation and standards as well as support system piping plans promoting longer seal life.
What basic tolerances are recommended for seal installations?
What benefit is the seal drawing to the overall installation?
Does the seal flush piping plan type really influence longer life?
What is the difference between a seal support system for a secondary containment seal and a non-contacting seal?

Section 4: Seal Environment – Failure Analysis

March 19: 1:00-2:00PM ET
This module covers seal environment and failure analysis. A seal is considered to have failed when leakage exceeds environmental or plant-site operating limits. The failure may occur before or after the seal has achieved its design life expectancy. Understanding the mode of seal failure can lead to extending the life of rotary equipment by improving seal design and material selection, installation and operating procedures, and environmental controls.

FSA Participation in ACEEE Extended Product Consortium

An agreement has been reached between the FSA and the Hydraulic Institute (HI) to sponsor the American Council for Energy Efficient Economy (ACEEE) effort to promote an extended product approach for electric motors, pumps, fans and compressors.  This would include sealing systems that are components of both pumps and compressors.  This initiative began October 2013 and will continue for 18 months with direct access to Utilities that offer rebate programs and the DOE through the FSA Government Affairs Committee. 

 

Discussions on the DOE standards process for electric motors, pumps, fans and compressors, with ACEEE and manufacturers of these products recognized that opportunities for motor system energy savings are much greater than savings from individual components. This led to a suggestion that industry develop a voluntary label for efficiency of an extended product that includes the driven equipment (e.g., fan, pump or compressor), the motor and associated controls. Sealing systems are an important consideration for energy efficiency of both pumps and compressors. This extended product label would provide the relative efficiency of the equipment as it is installed into a motor system application. Testing and labeling specifications for these extended products are being considered as a complement to minimum efficiency performance standards that are established through the DOE rulemaking process.

The energy efficiency community has long been aware of the large opportunity that exists from optimizing motor systems, but the ability of programs to realize these savings have been largely restricted to smaller systems that have very wide application and are easily measured.  Larger systems where the savings are of a much larger magnitude (e.g., denominated in 100s of horsepower) require a large investment in analysis and monitoring that is required for a custom rebate program. Prescriptive rebates have been restricted to efficient products, such as NEMA Premium motors, which have modest savings opportunity relative to the system opportunity.
