M&B Engineered Solutions - Rotating Machinery Balancing Seminar

Technical Training Seminar- machinery balancing
Description Our 3-day Machinery Balancing seminar teaches you how to perform corrective field balancing. It is based on understanding rotor response theory, the accurate acquisition and analysis of data, and applying the best field methods for a given machine design. We thoroughly explain the nature of machinery unbalance and teach how to balance without just "throwing a weight in." And we strive for maximum interaction between instructors and students to insure each gets the best possible value from the training. We cover Single Plane, Multi-Plane, and Overhung Rotors. Discussions focus on the diagnostic techniques for each machine application. We teach graphical and numerical techniques, and emphasize understanding and utilizing influence vector data. Case Histories are also presented to review common and unique field experiences, recommended field balancing procedures, cautions and site expectations. We also emphasize that attendees have extensive Hands-On experience in our Workshops to practice on the supplied Rotor Kits, all while using the latest diagnostic instruments. In our seminars, you will not just sit there and listen to lectures and pre-conceived experiments. You will conduct your own experiments, generate your own data, and produce your own results!! That is how you learn effectively. Optional fourth and fifth days are available during in-plant seminars to balance equipment at your facility. This immediately reinforces the training, while resolving problematic machines at your site. M&B will provide the analysis instrumentation, balancing instruction and oversight while attendees field balance one or more machines.

Machinery Balancing Exam Preparation & Certification (optional) In-Plant Balancing Example (optional) One (1) piece of plant machinery can be balanced as a group exercise, with M&B providing oversight, analysis & recommendations. This requires one (1) full additional day, and coordination between site and M&B personnel for scheduling and efficient execution.

M&B specializes in providing technical training related to condition monitoring, vibration analysis, predictive maintenance, shaft alignment, and rotor balancing, all customized to our customer’s specific needs. We provide seminars both on-site at your location, and off-site at hotels or other locations for centralized training.
