An Old Maintenance Mechanic’s Look at the Next Generation

This grainy photo was from my last day at a Weyerhaeuser mill in 1987.  I was a 26 year old millwright.  If you look closely, you’ll see an IBM computer in the storeroom.  We had another one we used for running Palomar Microlog vibration data collection.  We had a first generation laser alignment tool, but…

Why Don’t I Input a Coupling Diameter?

We often get asked why we don’t input a coupling diameter when performing a precision shaft alignment with the ACOEM laser alignment systems. The coupling diameter (or more correctly sweep of a face dial indicator) is only required when doing a rim and face dial indicator alignment or when the user wants to know the…

Influential Piping

There are many outside influences that affect a precision shaft alignment. One that seems to be overlooked is pipe hanger location and condition. The weight of the piping on the pump, when pipe hangers are missing or incorrectly spaced, can cause deformation of the pump housing and the base, essentially putting a strain on all…

4 Challenges Maintenance Teams Face

Our customers come from a wide range of industries, but they share many of the same pain points in their facilities. Over the years, we’ve consulted our customers to better understand these pain points and how our technology solutions can help to alleviate them. We found the following 4 issues resonated with the majority: Lack…

Cardan Shaft Alignment in the Belly of a Boat

  If you have read any of our blogs, you have seen we run into some unique alignment scenarios. During a recent class in a shipyard, there was a need to perform a Cardan Shaft Alignment in a boat with very little space to work in. It also required shooting the lasers through a hole…

Adding Process Points to a Data Collection Route

Sometimes other data can influence analysis when running your regular routes. This data can range from discharge pressure on pump to slide valve position on a chiller or maybe just bearing temperature just to name a few. With the Falcon and Nest this type of data can be collected and even trended in the Nest.…

Laser Alignment and the Effects of High Humidity

A recent question from a customer prompted me to write on this topic.  The question was essentially “Can we use the laser alignment tool in steamy conditions?” I have heard similar questions over the years for example: Can the laser alignment tool withstand use in wet conditions? How resistant is the laser alignment tool to…

Is it really Bolt Bound?

In a recent RT300 class during the field portion of the training, the team made the decision to take vibration readings on a motor/pump assembly that was very noisy and had frequent coupling failures. The RT300 diagnosed misalignment, cavitation and shock modulation. Then using the same RT300, they checked the alignment and it was indeed…

Aligning a “Bouncy” Motor!

  In recent years many new gas processing plants have been built to keep up with the demand for natural gas. Some of the process equipment for these plants are constructed on “modular skids” which are simply set in place, on the ground, then the piping is connected. During a recent training class, at a…

A “Typical – Atypical” Alignment

A colleague and client of ours called, in a bit of a quandary. “Ever seen anything like this?” he asked.  I had to answer “No, I have not”. This is a C-face motor.  It is typically mounted to a C-face flange, which connects to a vertically oriented pump.  But in this case, the C-face motor…

Fundamental Pump Laws

It doesn’t matter what size, shape or design of the pump its purpose is to move fluids. Head loss that must be overcome makes the task a bit more complicated and the type of pump makes a difference. Two of the basic pump laws are volumetric flow rate and pump power:   Volumetric Flow Rate:…

The Effect of Misalignment on Seals

Coupling manufacturers have an “acceptable” misalignment tolerance range that is typically much greater than precision shaft alignment tolerances. Why is that? Because flexible couplings are designed to allow for incidental movement of machines during operation. Seal manufacturers have very tight tolerances for allowable misalignment. Why? Because of how they seal. Typical mechanical seals have mating…

Precision Measuring Tools

Let’s talk about precision maintenance tools. “Precision” is the key word because it is required from the technician, their tools, and the work that they do. There are a ton of tools out there but these are the most common and important needed for the daily needs of a maintenance person, including but not limited…
