Lubrication for Industry - Second Edition

Description

Written for maintenance managers and practitioners, Lubrication for Industry provides a fundamental understanding of how and why effective lubrication practices are an essential aspect of industrial equipment maintenance.

Focuses on the practical daily aspects of lubrication that impact productivity. Covers, in detail, failure analysis, costing techniques, modes of friction, generations of lubricants, oil and grease classifications and evaluations (including animal/vegetable, mineral, and synthetic), viscosity and other oil and grease standards and characteristics, lubricant compatibility guidelines, how to calculate bearing and other lubrication requirements, preventive maintenance including wear particle analysis, and filter rating and classifications.

Provides ten case studies drawn from the author's consulting experiences that emphasize the importance of developing and implementing effective, long-term solutions for lubrication, maintenance engineering, and maintenance management.

Excerpt: CASE STUDY III - SYNTHETIC VERSUS MINERAL-BASED LUBRICANTS IN ADVERSE SITUATIONS PRODUCE SIGNIFICANT SAVINGS
"For the majority of situations, chemical wear first-generation lubricants perform adequately; for adverse conditions, such as extreme temperatures, the use of premium lubricants really pays off.

"A hydro utility study on energy reduction through lubrication engineering studied the use of synthetics in air compressors. The compressed air unit in the study was a 150-hp screw-type compressor that was recently rebuilt and utilized a standard 32 weight lube oil. A compressed air audit company gave the conveyor a clean bill of health. The power was monitored under varied load conditions and its power consumption noted. Because compressors run extremely hot, synthetic lubricants allow the press to run cooler, they also "desludge" or clean the compressor and allow it to run more efficiently, thereby reducing power consumption. Synthetics also allow for extended changeout intervals. The standard lubricant was replaced with a 32-weight fatty acid ester-type synthetic (second generation) lubricant. An energy reduction of 7.3% was gained by changing the lubricant, and the changeover also resulted in a cooler running compressor."
