Introduction
Training course introducion / brief
Machines that have been precision aligned run longer, and cost less to run. Alignment greatly affects the life of bearings, seals, shafts and couplings. Also, unbalance causes fatigue and reduces the life of bearings and can make looseness and resonance condi-tions far worse. This course will bring you knowledge and skills in using a vibration analyzer/balancer, or a simple sheet of graph paper and protractor, and balance a machine - without even having to remove it from the plant. You will learn how to recognize unbalance and set up the balance job for a successful balance.
Reverse-dial method
This course will equip you with the knowledge and skills so that you can use a dial indicator tool or laser alignment system to pre-cisely align two components together. You will learn how to recognize misalignment and successfully set up the alignment job. After reviewing the important reasons for performing shaft alignment, there will be a discussion about the pre-alignment checks and corrections, including how to identify and correct soft foot. The operation of dial indicators, and cover the rim-face method and reverse-dial method will also be discussed. The process will be demonstrated and discussed as well as how calculations are per-formed.
Laser alignment systems will be discussed; the benefits, basic theory of operation, and tips and techniques for successful use. And finally there will be discussion on how to move the machine and deal with all the problems that you are bound to encounter at some stage. We will also review how to deal with thermal growth, and how to approach a larger machine train.
Course Objectives
At the end of the training course, participants will be able to
- Have Good Information on how Shaft Misalignment causes Failures in Equipment.
- Explain how they work and understand how to measure runout on mechanical couplings and machinery shafts.
- Have understanding about how to construction and improve their capabilities and skills required to identify and measure misalignments in different machines and their causes and how to correct or monitor them.
- Have a detailed understanding of Advanced Time and Frequency Analysis Techniques and have acquired knowledge of Accurate Diagnosis of Antifriction Bearings.
- Gain Knowledge on measurement & correction Vertical and Horizontal Plan misalignment aligning Vertical mounted Equipment.
- Understand the practices in measuring and correcting “SoftFoot” problems and measuring run-out on Alignment de-monstrators.
