This equated to a maximum of 1’500 hp (1’110 kW) dual motor drive that could be configured to turn the rotor at, or above, its normal operating speed. The design of the drive system offered a maximum capacity of 150% of the motor power for a short period of time to start the rotor rolling. There is also the capability to add a third gearbox which is a turbo-drive. These were connected to a three-speed gearbox, which in turn was connected to a single-gear speed increaser. The two motors were connected inline, giving a 1’000 hp (740 kW) output, and could be operated independently. The original installation used two 500 hp (370 kW) direct current (DC) motors that were installed in the 1990s.
Sulzer can balance turbomachinery up to 30 feet (9 meters) in length, 8.5 feet (2.59 meters) in diameter, and up to 50’000 lbs (23 tonnes) in weight to speeds up to 40’000 rpm
Vibration diagnostics are used to analyze the radial vibration at the bearings to ensure that the best balance is achieved at operating speed as well as minimizing the deflection and vibration amplitudes during ramp up and coast down. The bunker itself is designed to accommodate turbomachinery up to 30 feet (9 meters) in length, 8.5 feet (2.59 meters) in diameter, and up to 50’000 lbs (23 tonnes) in weight to speeds up to 40’000 rpm.
#Fitted stock vs perfect balance upgrade
The installation minimizes the time required to balance a rotor and the latest upgrade will reduce that time even further.

Equipped with a vacuum chamber, it can run complete turbine rotor assemblies at full operating speed, and beyond if necessary. The independent, high-speed balancing facility in La Porte, Texas, is a specialist piece of diagnostic equipment that is designed to test some of the largest turbine rotors in the world. Sulzer is supporting these important assets with a comprehensive range of maintenance services, including high-speed balancing. Sulzer operates two of the very few independent facilities in the world and the site in Texas, U.S.A., recently underwent an upgrade project to improve both its flexibility and efficiency.Įlectrical generators are vital to creating the electricity we all use in our everyday lives and with increasing demand reliable performance is essential to minimize the risk of blackouts. High-speed balancing facilities are used to ensure optimum performance of large pieces of rotating equipment, such as steam or gas turbines. Drive motor upgrade delivers improved flexibility and efficiency for Sulzer’s high-speed balancing facility
