Portable Dynamic Balancing is required for turbines, fans, propellers, and other rotating components in machinery that cannot be removed from the field and brought to a balancing facility. While portable dynamic balancing throughout the world is similar in process to static dynamic balancing, it is much more difficult to undertake because portable dynamic balancing often has to be conducted under less than ideal conditions that are beyond the control of the portable dynamic balancing technicians.
Most portable dynamic balancing machine electronics use two-channel or four-channel data acquisition. Knowing how to identify a system that is in resonance is an important part of a portable dynamic balancing technician’s job. There are telltale signs in the raw portable dynamic balancing data from the portable dynamic balancing machine. The trigger for making a call if a system is in resonance usually starts with the technician having difficulty making balance corrections that produce efficient results. When carefully placed corrections result in the electronics overestimating the needed amount, or not being able to display the correct phase angle, system resonance should be a suspect.
Examples of facilities that may need portable dynamic balancing are power plants, utilities, mills, and other manufacturing plants. All types of rotating machinery need to be balanced and checked regularly, including blowers, fans, generators, and much more. Our technicians have used our portable dynamic balancing machines to correct many of these types of machinery.
