Industrial Lubricants Reduce, Re-use & Recycle

MINIMIZING THE DRAIN ON YOUR BUSINESS
Industrial Lubricants - Reduce, Re-use & Recycle


Summary


While lubricants are a relatively minor cost for many production operations, the cost associated with unscheduled break down of equipment as a result of lubricant failure can be significant. For example, an unexpected outage of a power station due to malfunctioning of a hydraulic control system would be extremely costly. 

It is therefore necessary for users to ensure that the condition of the lubricants in the equipment is always within operational specifications. 

Like many industrial components, over 80% of lubricants are being disposed of prematurely. Adhering to some simple guidelines can significantly extend the useful life of most lubricants resulting in reduced consumption, extended machine life, and minimized unscheduled shutdown maintenance.

Maintenance of Hydraulic Systems

The right way to perform maintenance on a hydraulic system utilizing the Maintenance Best Practices

Most companies spend a lot of money training their maintenance personnel to troubleshoot a hydraulic system. If we focused on preventing system failure then we could spend less time and money on troubleshooting a hydraulic system. We normally accept hydraulic system failure rather than deciding not to accept hydraulic failure as the norm. Let's spend the time and money to eliminate hydraulic failure rather than preparing for failure. I worked for Kendall Company in the 1980's and we changed our focus from reactive to proactive maintenance on our hydraulic systems and thus eliminating unscheduled hydraulic failure. We will talk about the right way to perform maintenance on a hydraulic system utilizing the Maintenance Best Practices.

Welcome Paperwork for Oil Analysis

If you are like me, you strive to reduce the amount of paper in your life. Now there is a new form of paper you will want to add to your life if you are involved with machinery condition monitoring and more specifically, oil analysis!

The ABC’s of Failure – Getting Rid of the Noise in Your System

For the past 40 years, I have observed many companies; including DuPont (where I spent 27 years) pursuing planned maintenance with the standard tools of planned maintenance: inspections, planning, scheduling, materials procurement, CMMS systems, etc. with the same results. They succeed for a while and get their percent planned and scheduled maintenance up to the 80+ only to see that drop back later to 60 I am amazed how many of the companies we work with have had this experience.

Interview with an Arc Flash Survivor

  1. On August 16th, 2007 Bill Giffen was involved in an Arc Flash incident with a 13,800 Volt Switch. He received 3rd degree burns to his left leg and 2nd degree burns to his arm, back and groin area.

Electric Motor Bearing Greasing Basics

One of the most important components of any electro-mechanical maintenance program is the lubrication of bearings. Yet, this vital aspect of preventive maintenance remains one of the least understood functions of maintenance. There is constant debate concerning whether a bearing should be ‘flushed,' a limited amount of grease added, how often or if the motor should be operating or tagged-out. Many motor manufactures outline the preferred, and safest, method for lubricating electric motor bearings. There are specific physical properties for this process in the motor bearing housing and in order to protect motor windings from contamination.

A Proven Electric Motor Regreasing Program

By Jerry S. Honeycutt, Tennessee Valley Authority

One of the most asked questions of grease lubricated motors is, what is the correct interval to regrease the bearings? This is usually followed by two questions, 1) how much grease should be added? and 2) what is the correct method for grease addition?

Pump Bearing Distress & Seal Failure New Statistics on the Value of Bearing Housing Protection

By: Heinz Bloch & Alan Roddis

It has been known for years that bearing malfunction often precedes mechanical seal failure in centrifugal process pumps. Statistical information to that effect has recently been published in a technical paper; it facilitates assessing the benefits of sound remedial action. The data of interest were presented at the Mechanical Sealing Technology Seminar, IMechE, London under the title "Mechanical Seal Reliability - What Realistically can be Achieved"1.

Grease-ology

By Kristopher Sonne, Trico Corporation

Grease selection is an important yet often overlooked part of many plant lubrication programs. It is common for plants to have in stock one coupling grease, one motor grease and one general purpose grease for everything else. The general purpose grease may be the proper grease for some applications but definitely not all. Selecting greases should be given the same care as selecting oil and not treated like the black sheep of the lubrication family.
