Acoem erbjuder AT-serien för laseraxeluppriktning. AT-100 är grundläggande, passar för pumpar och små fläktar. AT-200 är för industriella pumpar och större fläktar. AT-300 har avancerad precision för olika maskiner. AT-400 är flaggskeppet med innovativa sensorer för exakt uppriktning. EXO är specialiserad för explosiva miljöer. Valet beror på maskintyp och budget.
A customer called me recently with concerns about a pump alignment job he completed about six months earlier. He had checked the alignment again and found that the alignment values changed. He was concerned that he had done something wrong. I explained to him that he was performing the alignment correctly, however, the machine could have moved. How? He asked. Good question!

Har du någonsin lagt till antalet shims som ditt uppriktningsverktyg säger att du ska göra bara för att upptäcka att din maskin fortfarande inte är korrekt? Detta är en frustrerande men vanlig förekomst. Var det ett beräkningsfel eller gav ditt axeluppriktningsverktyg dig fel information? Mer än troligt är dina shims är skyldiga.
Tolerances for shaft alignment are typically expressed in terms of angle and offset. It is common knowledge that offsets cause confusion, but angularity often confuses those tasked with aligning or verifying alignments.
There are two parts that must be understood, proper phasing and angularity of the input and output shafts.
We are pleased to announce the launch of our new improved GuideU™ (UI), designed to maximize user productivity, facilitate intuitive reporting, and ensure a consistent user experience across all measurements.
There were huge differences between coupling alignment tolerances and precision shaft alignment tolerances during a recent Acoem RT-300 training class. Electric motors and centrifugal pumps fitted with grid couplings of model 1070T were aligned at 1800 RPM. A contractor performed the initial alignment on this fairly new installation.
When using a straightedge to perform a shaft alignment you won’t see angular misalignment.

To calculate the cost of misalignment, first determine the cost of the machine’s downtime.
We have several times discussed the differences between coupling alignment tolerances and precision shaft alignment tolerances. As stated in those text the coupling manufacture’s tolerances are for the coupling. As maintenance professionals we are concerned with the coupling, however we are more concerned with the bearings in the machines.
Predictive maintenance involves scheduled testing on regular intervals.
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 in a bulkhead.

It was a challenge, but the guys rose to it
Precision shaft alignment of wind turbine generators mounted on adjustable chocks is as straightforward as when aligning rotating machinery mounted on chocks down at ground level.
In the case of a recent NXA Training Class in a Vestas V82 we knew before going up-tower that one revolution of the adjustable chocks equals 1mm. Also, as there are 6 holes in the chocks, we calculated that the hole t
If possible we want to have the sensors in a horizontal plane when the live screen is activated so the sensors are in position to monitor the horizontal correction. For rotating machines with large mass or that are difficult to position precisely, this may be time consuming and/or not possible.
A customer called me, extremely frustrated, because he could not get a good alignment. “I’ve spent two hours trying to align this stupid pump!” he said. He blamed the laser, the “cheap” pump his company had, the bad base, his bad trainer (me), and anything else that came to mind.
I did not take it personally, because I’ve been there too! I listened to his frustrations, and let him vent. And
I had the pleasure of working with the maintenance team at a South Carolina manufacturing plant that had an outstanding alignment kit they rolled out to every alignment job.
Welcome ACOEM India. We strengthen our team with a group with long experience of shaft alignment
We recently received a customer request about shim safety. An employee at the customer site had experienced a “near miss” safety issue due to walking too closely to a machine, and getting their clothes caught against a shim. Since I have a scar on my right thumb caused by a 3 mil shim, I thought a discussion on shim safety might be in order!
Shims do three things:
Change the elevation of
