High speed vs low speed balancing
Balancing is essential to the proper functioning of your rotating equipment, but not all balancing services are equal. Low-speed balancing can cause engineers to miss balance issues arising from repairs or replacement parts that surface only when the machine is run under full-speed conditions. Undetected faults could cause vibrations leading to a damaging production shutdown. High speed balancing of turbine and generator rotors ensures effective testing to ensure minimal vibrations that allows power generators to avoid millions of dollars in losses, due to lost generation.
By eliminating vibration, high speed balancing will reduce wear-and-tear on your equipment and produce savings in overall reliability while reducing maintenance costs.
MD&A’s high speed balance facility in St. Louis, MO, is one of the most modern balance facilities for power turbines in the world. The facility was designed with both vacuum capability and the ability to excite generator rotors at high-speed, allowing the testing and balancing of both gas & steam turbine and generator rotors.
MD&A’s facility can balance rotors up to 49 feet in length and up to 180,000 lbs. in weight at speeds up to 4,320 rpm, as well as, speeds up to 12,000 rpm for smaller rotors.
