Hydraulic Institute University: Methods to Determine and Specify Rotodynamic Pump Dynamic Analysis (2025)

Date: November 19, 2024

Time: 1pm EST

PDH Credits: 1.0

Overview

This webinar provides guidance on how vibration caused by resonance may persist due to a lack of specification and upfront analysis. To minimize the chances of resonant vibration, dynamic analysis of the structure and rotating assembly is performed when the pump installation 'warrants' it. However, dynamic analyses are time-consuming, require expertise, and incur costs. It is not always clear at the time of purchasing a pump whether the installation justifies the expense of analysis. Furthermore, the purchaser may be unaware of the appropriate type and level of dynamic analysis to specify, resulting in poor specification, missed specification, or unnecessary analysis. The ANSI/HI 9.6.8 Rotodynamic Pumps – Guidelines for Dynamics of Pumping Machinery is the first American National Standard addressing this topic, providing methods to evaluate the risk and uncertainty of pump installations. This presentation will address the issue of resonance, review the importance of the guideline, explain its application, and discuss risk factors, uncertainty, levels of analysis, and methodology. Additionally, case studies will be presented.

Learning Objectives

• Understand the concept of resonance and its significance in causing vibration problems in pump installations.
• Recognize the challenges posed by the increasing use of variable speed drives in pumping systems and its impact on avoiding resonance.

• Gain knowledge of dynamic analysis as a tool to evaluate forces, frequencies, and interactions in pump systems, and understand the range of available tools and preventive measures.
• Understand the ANSI/HI 9.6.8 Rotodynamic Pumps – Guidelines for Dynamics of Pumping Machinery, including its purpose, types of analysis, methods for determining appropriate analyses, and sample specifications for pump dynamic analyses.

• Learn about the importance of evaluating construction attributes, site characteristics, and the effects of dynamic performance on equipment life and reliability.
• Understand the different levels of evaluation and validation recommended based on equipment uncertainty and application risk.

PDH Credits

One (1) PDH credit will be issuedupon completion of this live webinar series.

The acceptance of continuing education as it applies to fulfillment of the state licensing requirements for professional designations is at the pleasure of the individual state licensing boards. It is the responsibility of the individual participants to be knowledgeable about their state requirements.

Licensed Professional Engineers

Continuing professional development is a vital component to the engineering licensure process. Most state licensing boardsrequire continuing professional development as a condition for licensure and renewal of the license to practice engineering. Pre-approval of training providers and courses are not required bymost state licensing boards, except for the following:

Florida Board of Professional Engineers

Pump Systems Matter is a board-approved continuing education provider for the Florida Board of Professional Engineers: License # CEA361.

North Carolina Board of Examiners for Engineers and Surveyors

Pump Systems Matter is an approved continuing professional competency sponsor for the North Carolina Board of Examiners for Engineers and Surveyors: Sponsor # S-0523.

New York State Board for Engineering, Land Surveying, and Geology

Pump Systems Matter is approved as a sponsor of continuing education for professional engineers in New York State: NYS Sponsor# 241.
