An Overview of Vibration Tolerances
Presented August 2019
When it comes to machine vibration, “how much is too much” depends on a number of factors. Knowing which standard and/or tolerance applies requires a working knowledge of the standards and some basics of vibration terminology. This presentation provides an overview of where and how NEMA, IEC, ISO and Hydraulic Institute standards may apply to machines commonly encountered in EASA service centers.
- NEMA, IEC, ISO and Hydraulic Institute standards
- Basic vibration terminology
- What standard applies?
Target audience: Service center managers, engineers, in-shop and field service technicians can benefit from a clearer understanding of vibration standards and terminology.
Fundamentals of Shaft Alignment
Presented November 2012
Automatic alignment instruments are no substitute for the underlying process of aligning direct-coupled machines. This presentation explains the simple calculations that govern the alignment process. That understanding will allow technicians to use any alignment tool more effectively and deal with issues that confound the process.
Presented March 2016
This webinar recording provies a straightforward look at the simple relationship between shaft centerlines that is known as shaft alignment. Bypassing the common discussion of laser and manual instruments, this presentation gets to the heart of the shaft alignment process. Topics covered will include:
- Fundamental concepts
- How to visualize machine case position
- Practical solutions for moving machine cases
- Applying tolerances
- The foot-base-foundation connection
ANSI's New Shaft Alignment Standard
Presented July 2018
This presentation introduces you to ANSI's new shaft alignment standard. Topics covered include:
- A discussion of alignment Quality grades, AL 1.2, AL 2.2, AL 4.5
- Shaft alignment tolerances
- Issues affecting measurements
- Conditions affecting alignment stability
Target audience: This presentation benefits service center technicians and supervisors looking to improve shaft alignment knowledge and skills.
How to Balance Overhung Fans
Presented October 2011
Often an overhung fan is balanced in a single plane, only to find that the vibration has shifted to the outboard bearing. Attempts to use standard two-plane techniques may result in calculated correction weights that are very large and produce poor results. There are more effective ways to approach this common problem. This presentation shows a methodical approach and techniques for tackling this difficult balancing problem.
Target audience: This presentation is intended for field service balancing technicians, supervisors and managers.
Vibration on Belt Driven Machines
Presented June 2013
This presentation focuses on:
- Identifying belt vibration
- Identifying pulley pitch line run-out vibration
- Other vibration sources
- ODS analysis
The FFT (aka Spectrum): What It Is and Ways to Use It
Presented July 2012
This presentation examines:
- How the spectrum is generated from the vibration signal
- The effect of f-max ad resolution settings
- Averaging techniques
- Scaling and demodulation
Vibration Problems on Vertical Motors and Pumps
Presented December 2010
When motors are installed on top of vertical pumps, high vibration is a common problem. The problem may be mechanical, hydraulic or structural.
This presentation provides an understanding of the nature of this style pump and the various forces essential to diagnosing and correcting vibration problems on vertical pump motors.
