Gas Turbine High-Speed Balancing Services

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.

Proper balancing of turbine and generator rotors is extremely vital to ensure proper operation that allows the power generators to avoid millions of dollars in losses due to lost generation. The facility allows for effective testing to ensure minimal vibrations in any manufacturer’s rotor throughout testing.

High-speed balancing has effectively shown to minimize any testing stresses during repairs, ensuring effective usage when returned to operation.

Our facility will allow rotors to be rotated in a high-tech vacuum chamber at speeds up to 4,320 revolutions per minute, as well as speeds up to 12,000 rpm for smaller rotors.

At the heart of the high-speed balance facility is the control room, with modern capabilities that allow the ability to control almost any system remotely.  With four high-definition cameras mounted in the balance facility, MD&A’s balance engineers can not only receive measurements digitally but can also observe mechanical malfunctions in real-time during operation.

HGTP’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.
