Top 10 Reasons Why You Should Use Precision Laser Alignment

Perth, WA, Australia, 2018-Sep-18 — /EPR Network/ — A laser alignment system eliminates all the guesswork and unknowns associated with traditional measurement systems like dial gauges, straight edge methods and co-ordinate measurement machines (CMMs).

But their advantages stretch way beyond just the quality of the results that they deliver. Here are 10 of the top reasons why your operation should switch to precision laser alignment.

  1. PINPOINT ACCURACY. Unlike other systems, a laser tool can measure down to 0.001mm, even over long distances. The laser beam is always 100% straight and what’s more, laser systems automatically calculate for shims and adjustments values, so the results are always accurate. Unlike older technologies where accuracy may also be compromised because of reading errors, sticky dial hands and low resolutions, laser tools have extremely high resolutions for pinpoint accuracy.
  2. QUICK AND EASY SET UP AND FASTER RESULTS. The equipment is lightweight and easy to learn as well as use which means much shorter set-up times, preparation and measurements. It can also measure three axis directions in a fraction of a second, which results in further time-savings.
  3. MORE RELIABLE. Because lasers eliminate the possibility of human error and inconsistency, they’re more reliable and precise than any other method. Repeatability is another significant benefit and regardless of who is using the equipment and taking the measurements, the laser equipment will always deliver the same consistent results.
  4. ELIMINATES HARDWARE SAG. When a dial gauge is used, there is always a risk of some of the fixtures sagging which can compromise the accuracy of the displayed value. With a laser tool however, there is nothing to worry about with regards to fixtures dropping or sagging.
  5. SAVE BOTH MONEY AND TIME
    Faster set-up and operation coupled with the absolute precision of the results mean a laser tool can easily pay for itself in a matter of months.
  6. SOFT FOOT – HARD RESULTS. Machine frame distortion and soft foot issues can be problematic but unlike a dial gauge which only tells half the story, a laser alignment tool provides a true representation of what’s going at the feet of the rotating machinery as well as what’s happening with the movement between the axes of the shafts being aligned.
  7. VERSATILE. A quality laser alignment system does more than just measure alignment. These versatile tools enable optimum equipment set-up and operation, measuring base flatness, twist, squareness, bearing condition, spindle direction and straightness amongst others.
  8. ABILITY TO MEASURE WITH A SMALL SHAFT ROTATION. Measuring with a traditional dial gauge can require a rotation anywhere between 1800 and 3600. However, a laser alignment tool can take a complete measurement with a much smaller shaft rotation, sometimes as little as 400 which is advantageous especially when machine parts prohibit a full rotation.
  9. ENHANCED DATA MANAGEMENT. Advanced software solutions bring data management to a new level. PDF reports can be generated directly from the instrument, results can be examined in real time and the information can be integrated with an existing software system for record-keeping and reference purposes.
  10. REDUCED ENERGY CONSUMPTION. Half of all machine failures are caused by alignment errors, so it is critical that errors are identified and removed as early as possible – or better still, are prevented from happening in the first place. When machinery is well-aligned and running smoothly, it will consume less energy than a poorly-aligned one which is another compelling reason for choosing fast, accurate and reliable laser alignment technology.

Given that laser alignment tools are simple to learn, easy to use, highly accurate and deliver a wide range of benefits, there’s no need to continue using complicated dial gauges and other older technologies which may be compromising the efficiency of your rotating machinery as well as compromising your bottom-line.

Nexxis has worked with many customers across a diverse range of industries to develop customised solutions for their particular alignment requirements. Deciding to go for laser technology is a major step towards more efficient, cost-effective and productive machinery, but it’s critical that the tool – or combination of tools and accessories – that you choose are right for your unique needs in terms of cost, functionality and relevance to the application.

The Effects Of Misaligned Equipment

Perth, Western Australia, Jun-27-2017 —  /EPR INDUSTRIAL NEWS/  — Nexxis are one of Australia’s leading suppliers of specialist remote visual inspection (RVI) technology and non destructive testing (NDT) equipment and they have all the answers to your equipment misalignment problems.

Industrial operations are losing huge sums of money because the centrelines of the shafts of their rotating equipment (such as pumps and motors) aren’t running on the same axis and are therefore misaligned – with some industry sources going as far as saying that shaft misalignment is to blame for up to 50% of all machine breakdowns.

And when you consider that a survey by a leading rotating equipment service company found that less than 10% of machines that were evaluated were aligned within acceptable tolerances, misalignment is clearly a widespread problem.

Here are some of the costly and damaging effects of equipment that is poorly aligned or misaligned.

Excessive vibration
Misalignment is one of the leading causes of vibration problems – and as the reliability of the machine corresponds directly with the level of vibration, excessive radial and axial vibrations will impact negatively on performance. All rotating equipment will produce a certain level of noise, but when the shafts are misaligned and the equipment vibrates excessively, noise levels will also escalate correspondingly.

Premature failure of seals and bearings
Accelerated failure of seals and other parts is costly – and even the slightest misalignment can result in excessive force and stress being put onto the bearings and seals. Replacement parts are expensive, plus there’s also the risk of damage and contamination of other components from the leaking fluid from the stressed seals and bearings.

Increased energy costs
Misalignment correlates directly to higher power consumption as the machines are less efficient and therefore draw greater amounts of energy.

Excessive heat
In the same way that variations in temperature can cause misalignment, misalignment can cause machines to overheat which results in lubrication issues as well as safety risks.

Broken shafts
Misalignment can cause the shafts to break or crack – and this can lead to unplanned downtime and production problems as well as costly equipment repair.

Higher operating costs, loss of production and increased maintenance costs
Misaligned machinery generally has a shorter service lifespan and this premature failure of capital equipment adversely affects outputs as well as negatively impacting the operation’s balance sheet. Higher maintenance costs, costly downtime, unexpected capital costs for equipment replacement, increased inventory for spare parts and even the potential for catastrophic machinery failures are all consequences of misalignment-induced mechanical failures.

Inferior quality outputs
Misaligned machinery can also result in inferior or defective products which can impact on profitability.

Implementing a careful and thorough preventative maintenance programme will go a long way towards minimising the risk – and the associated costs – of misaligned machinery.
