Shaft Alignment
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…
Read MoreInfluential 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…
Read MoreCardan 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…
Read MoreLaser 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…
Read MoreIs 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…
Read MoreUsing Your Laser Alignment Tool to Measure Pipe Strain Induced from Tightening Flanges
I recently had the pleasure of teaching an alignment class for a Midwest company involved in pipe fabrication and installation. Their primary concern wasn’t so much in precision shaft alignment, but in being able to measure the effect pipe strain has on alignment. Before I arrived, they had told me they had fabricated a rig…
Read MoreDon’t Forget a Lift Check!
A lift check isn’t always done when performing a precision shaft alignment, nonetheless excessive lift can be the cause of alignment frustration. Here is a recent example from a very experienced aligner. This particular alignment was on a 150 HP motor driving an extruder through a gearbox. The horizontal alignment came in as…
Read MoreAligning 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…
Read MoreA “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…
Read MoreCondition Monitoring Tools – How to Choose for Your Facility
Monitoring and maintaining the condition of your machines is essential to maximizing efficiency and prolonging machine life. You need human expertise and the right tools in order to have an effective condition monitoring program. When choosing from our suite of condition monitoring tools, it is important to look inside your toolbox and take inventory. To…
Read MoreThe 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…
Read MoreOut-Of-The-Box Thinking
Out-of-the-box thinking is sometimes required in these uncertain times we are living in. This became clear on a recent training assignment in Northeast Nevada. Improvisation became the backdrop for my class with the mining maintenance technicians of Direct Force Maintenance, of Winnemucca Nevada. The current cultural changes facing our nation provide challenges for conducting on-site…
Read MoreCommon Shaft Alignment FAQ
We get asked a multitude of questions in our training classes, which we appreciate. But a few questions pop up almost every time. Here are some of our most common questions and answers. QUESTION: Sometimes on small machines, I don’t have enough room on the shaft to mount the laser. Can I mount it…
Read MoreRecycle, Recycle, Recycle
Often times customers ask the question how can we keep it going? “How can I continue to train my technicians with the principles they learned in your class?” Craftsmen and women often admit we don’t perform precision shaft alignments often enough to keep our skills current. To this I say recycle! One of the…
Read MoreHow Can We Help You-Let Us Count the Ways!
While hands-on training is best, sometimes technical support requires more. A recent blog lists all the different ways you can reach out to us https://acoem.us/other-topics/vibralign-training-during-covid-19/. A few weeks ago, a wind technician was attempting a precision shaft alignment in a GE 2.x wind turbine using a Fixturlaser GO Basic GE Wind. He was familiar with…
