What is 'Laser Alignment'?
Laser shaft alignment is a form of corrective maintenance. A modern replacement of traditional DTI (clock-gauge) alignment, taking a significantly less amount of time and having greater accuracy, it is the way forward in shaft alignment. A misaligned machine creates a damaging force in particular angles within the rotation, this force causes damage over time to various parts of a machine (coupling, bearings, seals, gears, etc...) Alignment uses a laser and a receiver which measures the lasers displacement upon rotation, giving correction values which can be performed to ensure the machine is then properly aligned and the damaging forces are reduced significantly.
What are the benefits of 'Laser Alignment'?
There are many benefits to why laser alignment is performed:
Significantly extends MTBF (Mean Time Between Failures) - the average time between failures is increased by laser alignment by reducing the damaging forces which machines are often left subject to. These forces are constantly applied to crucial parts of machinery such as the bearings, coupling, gears and seals.
Reduces operational temperatures - operating temperatures are often increased by misalignment forces, this temperature increase can lead to premature failure and unnecessary downtime. Couplings often show the highest increase of temperature due to misalignment, therefore coupling life is significantly longer once correctly aligned.
Warranty purposes - when installing a new machine, it is often written in the small print of the warranty information that; if installed and not aligned correctly, the warranty may be void. Even new machines aligned at manufacturers require a new alignment once installed on site.
When is 'Laser Alignment' required?
Laser alignment may be required for numerous reasons:
Repaired or overhauled machinery - when reinstalling an overhauled asset, it is key to ensure the machine is correctly aligned so that the repaired unit lasts as long as possible, and that more problems are not generated by re-installation.
New or replacement machinery - When even newly supplied units even if supplied as a full unit on a base-plate require to be aligned as the alignment is easily changed when transporting and securing down base-plates. Replacements should also be aligned.
Moved machinery - If an asset has been relocated, it is likely that the alignment has been interfered with in the process and this will require a re-alignment on completing the relocation.
Why choose PFE Limited for your 'Laser Alignments'?
We have an extensive knowledge and enthusiastic drive when it comes to our work, we will always go the extra mile to ensure our service is the best service we can possibly provide. We will always strive to achieve an alignment as close as possible to 0.
PFE offer tailor-made reporting for every client, every part of the report can be modified to suit your needs and/or requirements, we are proud of our in-depth reports and we are sure you will be happy with our reporting standard.
With competitive pricing and an unrivalled quality of service, PFE Limited will meet your laser alignment needs.
How we will perform a 'Laser Alignment'
With the unit isolated electrically and any hazards previously assessed, PFE Ltd will remove any coupling/shaft guards required and fit our alignment equipment. We will proceed to take various readings which usually involves rotating the shaft of the equipment by hand, once completed PFE will refit any guards removed unless otherwise specified not to.
Initial alignment figures and final alignment figures will always be available. As a minimum, our report will include the final alignment results which shows alignment visually (like above) and any tolerance tables used. Our reports are completely tailored to your needs, so initial alignment figures are always available and any other modifications or extra information you wish to be displayed on the reports.
