Predictive Maintenance

1. Laser Alignment

First it’s important to know why is it important to have a good alignment?

Misaligned shafts are recognised as one of the greatest contributors to plant breakdowns, due to the increased forces placed on bearing, mechanical seals, internal components and motor drives.

This leads to:

  • Premature wear of bearings , seals , gaskets, ...
  • Bearings overheating
  • Excessive Vibration
  • Additional energy consumption

For these reasons, it’s essential to check the alignment of its equipment and, if necessary, correct it regularly. To do this, it is necessary to use very accurate hardware and at the same time easy to use device to minimize the maximum premature wear of the machine and to achieve the shortest possible intervention to avoid delay in the process.

The principle of laser alignment on a machine consist in determining the relative displacement of a laser beam placed on a side of the shaft. This laser is reflected by a mirror located on other side of the coupling. This relative displacement is measured during manual rotation of the shaft line. After treatment of the relative motion data for edging, corrections are provided by the software.

I-care offers different types of device whose main difference lies in the complexity and number of equipment to align. Indeed, each of the proposed I-care laser alignment devices has its own characteristics.

Whats benefits?

  • Reduction of energy consumption
  • Reduction of constraints (mechanical, thermal, ...) on the components of the installation
  • Reduced temperature and vibration generated by the equipment
  • Ability to align according to target values.
    • Gear couplings, for example, require some edging to ensure proper lubrication of the gearing.
    • Thermal growth
    • Slide bearings (dynamic movement)
  • Precision
