Shaft Analysis and Bearing Life Calculations in Rotodynamic Pumps: 1- Part Webinar| November 6, 2024

Shaft Analysis and Bearing Life Calculations in Rotodynamic Pumps

Date: November 6, 2024, |Time: 1pm EST

PDH Credits: 1.0

Overview: 

This presentation aims to equip engineers with a comprehensive understanding of shaft stress, shaft stretch, and bearing life calculations in rotodynamic pumps. Attendees will gain fundamental knowledge, including key definitions, equations, and calculation procedures related to shaft behavior and bearing life. The presentation covers the effects of shaft stress and stretch, methods to minimize these forces, and practical insights into calculating L10 bearing life, including adjustments for reliability, material improvements, and lubrication conditions. Additionally, the session will address the significance of pump design, common bearing types, lubrication methods, preload and clearance, dynamic and static load ratings, and calculation factors.

Learning Level - Intermediate  

Intermediate level training is designed for individuals who have some experience and basic knowledge on the topic. It builds upon basic concepts and expands the breadth and depth of understanding supporting the development of skills. The basic level training within bundle modules 1, 2 and 3 prepare them for intermediate level training provided in bundle module 4.

Audience 

Individuals looking gain in depth technical knowledge or those looking for a refresher on applied fundamentals, including experienced maintenance and operation personnel, pump system designers and owners, technical sales, and engineers.

Learning Objectives:

• Gain a comprehensive understanding of shaft stress and shaft stretch in rotodynamic pumps, and how to analyze it to improve pump design, operation, reliability, and prevent potential failures.

• Describe the different types of stress (shear and torsion) experienced by shafts, the causes and effects, the calculation procedure for determining stress levels, and propose appropriate methods to minimize both shear and torsional stress.

• Acquire knowledge of shaft stretch in vertically suspended pumps, the causes and effects, the calculation procedure, and recommend methods to compensate.

• Acquire knowledge of calculation procedures used in determining basic L10 bearing life and the adjusted L10 life to account for elasto-hydrodynamic theory of lubrication. 

• Learn how to adjust the basic L10 rating life to accommodate different reliability requirements and understand the influence of lubrication film thickness on bearing life, utilizing equations and factors for accuracy.

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 or professional 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 boards require 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 by most 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
