MSI was tasked with designing a subscale (1/6th ) axial hydro-turbine utilizing a belt system to drive a generator. The turbine rotor consisted of a CNC machined wheel with teeth machined on the shroud to utilize an industrial belt for transmitting power. A full turbine system from inlet to draft tube was designed and tested in Massachusetts.
A steam turbine at a waste-to-energy facility in the Northeast underwent a scheduled repair, at which time the turbine bearings were reworked, after which the turbine periodically experienced very high amplitude shaft vibrations.
A boiler feed pump (BFP) driven off of the main steam turbine via a fluid drive was experiencing high vibration levels leading to frequent replacement of the fluid drive bearings.
MSI was contracted to understand and help solve a high vibration problem on an aero-derivative gas turbine driven generator.
