Vibration Measurement and Acceptance Criteria for Centrifugal Pumps – API 610 (0.6 CEUs)

Course Code: MEC124

Description

This is an advanced course on vibration measurement of “Centrifugal Pumps for Petroleum, Petrochemical, and Natural Gas Industries” as required by the API standard 610 – 12th edition. The vibration measurement is a part of the section 6.9 of the API standard – “Dynamics”. Full understanding of the requirement of vibration measurement includes the understanding of the balancing requirements of rotating assembly, natural frequency and resonance and fundamentals of vibrations.

In this course we will cover the fundamentals of vibration to the extent necessary to comprehend the stipulations of the standard and subsequently go through the precise interpretation of the requirements of the standard. After going through this course, the participants will be able to understand the rationale of the measurement, they will understand the terms and terminology used in the standard and the meaning of these in practical terms. They will be able to use this standard as an acceptance criterion after the vibration measurement and the analysis has been completed. Reference is made to several other standards which will be explained as much as is necessary.

Objective

The course objective is to:

Understand the vibration measurement criteria applicable to centrifugal pumps conforming to API standard 610.
Have an introduction to the vibration limits for different types of - Overhung, Between Bearing and Vertically Suspended pumps,
Be acquainted with the allowable vibration limits for high energy pumps,
Go through the recommended vibration measurement procedure and vibration measurement instruments,
Learn to know the significance of each measurement limit and its practical implication.

Target Audience

Managers, engineers, supervisors, and professionals dealing with pumps and pumping systems, in refineries and oil and gas sector and allied industries, responsible for:

Preparing vibration tests and acceptance specifications

Conducting inspection, testing and approvals,

Condition monitoring and delivering plant reliability,

And all those aspiring for additional learning and knowledge.

Level of Course

Vibration measurement of critical application pumps according to API standard 610 requires an understanding of the vibrations and vibration analysis, including Time Waveform analysis, Frequency spectrum and FFT analysis, data acquisition including different types of transducers and their applications, signal processing and equipment knowledge. This course also requires an understanding of dynamic and hydraulic excitation forces in a pumping system and the manifestation of these forces as discrete vibration frequencies related to specific sources such as vibrations in rolling element bearings, journal bearings, rotating shafts, unbalance, alignment, and several others.

This course covers 3 disciplines – namely

The vibration measurement and data acquisition,
Analysis of vibration test results as a diagnostic tool, and
Pump and pumping system dynamic behavior – rotodynamic

Learning Objectives

This is an advanced level course which requires an understanding of dynamic and hydraulic excitation forces in a pumping system and the manifestation of these forces as discrete vibration frequencies related to specific sources such as vibrations in rolling element bearings, journal bearings, rotating shafts, unbalance, alignment, and several others.

After you attend this course/workshop, you will be able to:

Acquire a basic understanding of vibration measurement and vibration analysis,
Be able to set-up and guide vibration data measurement process,
Be able to read and interpret vibration data,
Be able to judge the health of the equipment and its compliance or otherwise to the acceptance criteria, and
Be able to adjudicate non-conformities and deviations in the measurement process, at the analysis stage or variation with respect to the laid down standard.
