KD700 · Machinery Diagnostics - Base Unit

Base unit with vibration analyser

Experiments
  • Introduction to vibration measurement methods on rotating machinery systems
  • Fundamentals of shaft and bearing vibration measurement - variables, sensors, signal types
  • Influence of speed, shaft layout and sensor positioning on the measured vibration signal
  • Field balancing of rigid rotors in one and two planes
  • Misalignment between motor and shaft, and its correction by shaft alignment
  • Mechanical looseness - effect of a loosened mounting on the vibration spectrum
  • Interpretation of frequency spectra of rotating machinery
  • Use of a computerised vibration analyser for time- and frequency-domain analysis
  • Quick vibration and non-contact temperature checks at the machine with the portable meter
KD700
Description
    The KD700 is the modular base bench of the Sangari machinery diagnostic training system. A three-phase asynchronous motor with frequency converter drives a shaft with two flywheels in interchangeable bearing blocks, under an interlocked transparent cover. Unbalance, misalignment and mechanical looseness are set up on the bench, then measured and corrected. The unit is supplied ready to measure, with accelerometers, a computerised vibration analyser and a portable vibration meter, and stands on a support frame with anti-vibration mounts. Its rigid aluminium plate with slots allows quick, precise assembly of further setups - belt drives, gears, couplings and pumps - when combined with the KD710-KD719 expansion experiments.
