Web Based Vibration Analysis Programs

Drop a bearing (oops!), impact an interference fit hub, coupling etc., that seized onto a shaft (hammer time oops!), beat a bearing onto a shaft or into an housing, hit the machine with the big hammer to move it (no jacking bolts oops!), let that spare machine sit on the warehouse shelf or in the field for months or even years with no rotation (oops!)? And the list could go on and on…we’ve all probably been guilty of at least one or more of these infractions at some point. “What’s the big deal anyway?”

Oil analysis is a valuable tool for determining the condition of lubricating oil and the equipment it lubricates. It is best used as a trending process — not a one-time event. When collecting oil samples for routine oil analysis, where and how should you do it?

Unfortunately, when it comes to steam traps, people often ignore them. There's a complacency about them that is costing steam users much more than they realize. The hard reality of a plant maintaining its boiler and forgetting about the rest of the steam system can be a horribly wasteful proposition. Losses can include not only wasted energy but replacement of damaged equipment and misuse of man-hours. It is not uncommon to discover system losses in the hundreds of thousands of dollars.

Something that worked well for us is if you make a visual change in the project one thing is we talk about planning and scheduling in a reliability of projects. We talk about preventive maintenance and reliability projects. What could easily happen is that you start documenting inspection routes and somebody sits in a corner documenting inspection routes right? We tried to work on our planning and scheduling…it may not be very visual on the floor. So, sometimes it could be a good idea just to make sure it's okay…let's pick our top five or top 10 piece of equipment and let's fix them up.

What is the difference between Brinelling and False Brinelling? What causes Brinelling and False Brinelling? Brinelling is an indentation in the surface of a material; a permanent plastic deformation that occurs when the yield strength of the material has been exceeded.

This installment of the cooling water systems series highlights the most common, but by no means all-inclusive, corrosion mechanisms in cooling systems.

We are embarking on a voyage of discovery that entails us calling at the following way stations: Part 1 – Calculate natural frequency of a pipe Part 2 – Calculate VIV Vortex Induced Vibration affecting the pipe Part 3 – Calculate the effect of flow induced vibration as flow rates change Part 4 – Determine the severity of the vibration to see if it is acceptable as is or if we need to make modifications.
