  • Page 91 Balancing: Introduction Chapter 4: Balancing Increased vibrations on machines are undesirable phenomena. They impair product quality, place additional strain on components and, last but not least, reduce operational safety. The most frequent cause for these increased vibrations is imbalance. The high centrifugal forc- es that result lead to premature wear of machine components such as bearings and seals, for example.

  • Page 92: Balancing On Machines With Rotating Masses

    Balancing: Introduction Basically, the consideration of whether to carry out balancing in one or two planes depends on the specific machine situation, i.e. on the balancing behavior of the rotor and the vibration behavior of the machine. Simultaneous balancing in two planes is quicker and more precise than successive balancing measurements in each of two in- dividual planes.

  • Page 93: Assembly

    Balancing: Preparations Preparatory activities Preparations include the mounting of the measurement components. The machine must be..disconnected before carrying out any work on the machine..protected against being switched on again inadvertently! WARNING! Assembly 1. Find out the cause of the imbalance visually and fix it if possible, e.g.: Remove any coatings from the impeller, fasten any loose bal- ancing weights or tighten any loose screws on the foundation.
  • Page 94 Balancing: Preparations 4. Attach a reference mark on the shaft for the trigger sensor while the machine is at a standstill (s. page 3-36). 5. Mount the laser trigger sensor (VIB 6.631) with the trigger bracket (VIB 6.632) on the machine (s. page 3-36). 6. Connect the vibration transducer to the measurement instrument.  • The balancing RPM should lie as close as possible to the operat- ing RPM. If this is not possible due to high vibration values, start at a lower RPM and approach the operating RPM step-by-step in Note several balancing runs.

Switch the machine off. In the trial run the imbalance should change enough to steadily reduce the residual imbalance in the subsequent balancing runs. If the imbalance changes only slightly, increase the trial weight.
