Portable field balancer
January 1st 2005 Schenck Balancing and Diagnostic Systems, has announced its re-entry into field balancing and vibration analysis with the SmartBalancer. The new Schenck SmartBalancer is for checking the vibration of an assembly and for accurately identifying and correcting unbalance in rotating machinery.
With the SmartBalancer, operators have complete on-site field balancing capability and the compact, battery powered instrument enables rotors to be balanced quickly, accurately and cost effectively without dismantling the machine. Rotors of almost any size or weight can be balanced in one or two planes - statically and dynamically.
With its ease of operation, universal application and field proven accessories, the SmartBalancer makes field balancing fast and easy - even for less experienced staff. Operators are prompted through the sequence of steps required to measure and eliminate rotor unbalance, using up to four measurement points to reduce error, provide complete versatility and superior accuracy. A variety of combinations are possible such as simultaneous horizontal, vertical and axial measurements, or two horizontal and two vertical measurements.
The new SmartBalancer performs a broadband measurement of absolute bearing vibrations to compare measured values with specified limits to ascertain whether a machine is operating within its specified vibration level, or if this is exceeded whether field balancing is necessary. To determine the causes of vibration, the SmartBalancer also offers FFT (Fast Fourier Transform) analysis with constant absolute bandwidth and SmartFFT with constant relative bandwidth.
Both methods enable measured vibrations to be separated into harmonic portions and displayed with frequency and amplitude in the form of spectral lines. Results can be viewed numerically or in polar display to provide an easy to read graphical representation. More articles from Schenck Ltd: |
