Ultrasound Predictive Maintenance Handbook

This Handbook provides information on using ultrasound instruments to detect, monitor, and trend mechanical faults. Fault conditions can lead to failure. The cost of failure extends way beyond the price of a bearing. Production runs can be ruined, productivity losses add up while employees sit idly by. Items covered:

• What produces ultrasonic changes when mechanical components start to fail


• How to set up an instrument for inspection


• How to trend bearings


• How to prevent overlubrication


• How to determine when a bearing needs lubrication


• How ultrasonic spectral analysis helps identify bearing faults, gear problems and compressor valve leakage, and other mechanical faults.

Steam Trap Guide

Steam is a costly utility. Wasted steam costs energy dollars and inefficient use of steam can affect product quality. This guide explains how the different types of steam traps operate, how properly working traps work, what can go wrong, and how to test traps. Items covered:

• What a steam trap does


• Inverted Bucket Traps


• Thermostatic Traps


• Thermodynamic Traps


• Float and Thermostatic Traps


• Fixed Orifice Traps


• How to test traps


• How to determine the cost of leaking traps


• Steam flow through a steam trap orifice.

Compressed Air Guide

According to the U.S. Dept of Energy (DOE), compressed air is the most costly utility in plants today. They have issued a Compressed Air Challenge to industry to reduce compressed air usage by 10% by the year 2005. That year is approaching quickly. This booklet provides helpful tips on how to conduct a compressed air survey using ultrasonic instruments. Cost analysis charts and formulas will help calculate and report the dollar loss/savings of your compressed air survey. Items covered:

• Setting up a compressed air survey


• Calculating the cost of compressed air


• Chart for discharge air through an orifice


• How to calculate cfm loss as dollar loss per year


• Quantifying compressed air loss and savings from a survey


• Calculating the cost of air per thousand cubic feet (MCF).
