Upcoming Hydraulic Institute, Pump Systems Matter Webinars Focus on Variable Drives, System Assessment

The Hydraulic Institute (HI) and Pump Systems Matter will be staging web-learning events in the month of July. Two notable webinars are Fundamentals of Pumping System Assessments and a four-part series on variable speed drives.

Hydraulic Institute logoHI says the purpose of Fundamentals of Pumping System Assessments: An overview of the ASME Energy Assessment for Pumping Systems Standard, which will be held on July 16 at 1 p.m. ET, is to familiarize operators with the EA-2-2009 standard, which sets the requirements for conducting and reporting results of a pumping system assessment that considers the entire pumping system, from energy inputs to the work performed based on the inputs.

The one-hour webinar will provide a background to “superior energy performance,” scope and definitions, organizing the assessment, conducting the three levels of assessments, data analysis, and reporting and documentation. Attendees will also learn how the ASME standard sets the framework for conducting pump system energy assessments, defines assessment parameters and minimum requirements, assessment procedural guidance, and the three assessment levels appropriate to specific situations.

Meanwhile, the 4-Part Variable Speed Drives Webinar Series begins July 18 and ends with the fourth session on Aug. 13. Each session lasts approximately one hour. The sessions are:

1. Intro 101, which introduces variable speed drives (also known as variable frequency drives, VFD) used to vary the speed of electric motors driving pumps and their benefits. Attendees will learn that, in the correct applications, variable speed drives can generate cost savings and reliability improvements. July 18, 1 p.m. ET.

2. Application & Installation Considerations, which will describe environment considerations such as temperature, altitude, and space requirements; electrical system considerations such as harmonics, radio frequency interference, power quality; and application considerations such as load torque. July 23, 1 p.m. ET.

3. Protection for VFD & Proper Output, which covers the protection of the variable frequency drive system and managing the interaction between the system and the pump motor. The webinar will also cover installation considerations such as short-circuit protection, harmonics, cable length and output filter considerations, and surge protection. July 30, 1 p.m. ET.

4. Troubleshooting, which will discuss problems often encountered by VFD users and the appropriate diagnostics. Aug. 13, 1 p.m. ET.

The series costs $229, and individual sessions cost $79. HI members receive 25 percent discounts.
