Vibration measurement and allowable values for rotodynamic pumps ANSI/HI 9.6.4 and ISO 20816 (0.6CEUs)

Course Code: MEC115

If you are unable to attend any of the sessions a recording will be made available.

Description

Vibration measurement of rotodynamic pumps is useful for condition monitoring, diagnostics, and asset health assessment. This course explains the specific guidelines given in ANSI/HI 9.6.4 and ISO 10816 for assessing the severity of vibration measured on non-rotating parts of rotodynamic pumps at site and during factory acceptance tests. ISO 10816 includes guidelines for assessing relative vibration of the rotating shaft.

Objective

The participants will be able to learn/ refresh the basics of vibrations, learn pre-requisites for vibration measurement, understand how to apply ANSI/HI 9.6.4 standard and understand how to apply ISO 10816 standard.

Target Audience

Managers, engineers, supervisors, and professionals in general industry and responsible for:
Preparing vibration acceptance specifications,Conducting inspection, testing and approvals,Operations and maintenance, condition monitoring

Level of Course

This is an intermediate level course. It requires basic understanding of vibrations in rotating machines, engineering knowledge and competency in calculations. An exposure and understanding of rotary machines in a plant or factory and some knowledge of vibration measurement instruments is helpful.

Learning Objectives
