It will be useful for the preventive maintenance of small and medium-sized turbo machines and large electric drive machines. Let's utilize field balancing for long-lasting performance.
We have set up CABS, which is utilized for field balancing to address shaft vibration and dynamic balancing issues in large turbo machinery (such as steam turbine generators, gas turbine generators, blowers/air compressors), for small and medium-sized machines and motor-driven equipment. The challenges posed by bearings cannot be completely avoided, as there will always be slight imbalances in the rotating body or misalignments during assembly (such as centering or distortion), regardless of how well the bearings are made. Moreover, if field balancing is not performed properly after assembly on long shafts or flexible foundations, it can lead to problems caused by vibrations later on. CABS is actively used for field balancing and continuous monitoring of conditions in large turbo machinery. From this, we have condensed the core functions specifically for field balancing tasks into CABS-M. Electric drive machines are becoming larger daily, and while elastic forces increase, the structure of the foundation is shifting from rigid to flexible, complicating the vibration mechanisms. This helps in understanding and analyzing the vibration state. Please feel free to contact us at https://power.mhi.com/jp/group/eng/business/products/cabs.

Applications/Examples of results
CABS has exceeded a total shipment of 500 units to date. We have sufficient track record. - Steam turbines - Gas turbines - Axial flow compressors - Pumps - Fans and other turbo machinery, as well as - Generators - Marine propeller shafts are being utilized. For previous models, it is beneficial to use the same measuring instruments to collect comparable data when checking balance during quality control before factory shipment and when checking centering and field balance after setup on-site. This method is meaningful for balance adjustment, data management, and asset management, allowing for long-term use. Rotating machinery aimed at high performance and cost reduction tends to have increasing elasticity. The confirmation of dynamic balance is becoming increasingly important as part of product quality management and for inspecting the condition of equipment that will be used for a long time. We can also add current waveform/harmonic monitoring functions for electric motors. Additionally, data integration is possible.
