Rotating Machinery

Xi are able to diagnose problems with rotating machinery and complex dynamic systems, providing solutions for rotational dynamics and structural related issues.

Working alongside machine operators and OEM’s, Xi provide accurate reports on dynamic tolerances for non-reciprocating machinery in line with relevant ISO Standards. Some common issues with rotating machinery, which Xi can assist with, include:

  • Frequency Matching
  • Shaft Misalignment
  • Casing Vibrations
  • Shaft Oil Swirl
  • Torsional Dynamic Issues

Many machinery upgrades and installations can end in unwanted and potentially harmful vibration issues in dynamic systems. By determining the dynamic response of a system, Xi can design alterations to remove problematic vibrations and remove the risk of expensive repair and maintenance operations later in the component lifecycle.

Xi’s engineers are experienced in the measurement and modelling of dynamic systems and have specified many design solutions and alterations for clients. The main objective is to improve design and reduce downtime to prevent failure and loss of production.
