I will be attending the EPRI Summer 2019 Steam Turbine Generator Workshop in Albuquerque, New Mexico. The workshop Aug 19th through the 23rd. I will be manning a vendor booth on the 19th and 20th. If you plan on attending, stop by for a chat.
Hydrogen Cooled Generator Upgrades
August 29, 2018The first hydrogen cooled generator was put into service by GE in 1937. Many of the design features of those early generators still persist today. TRI Transmission and Bearing Corp. has successfully implemented many upgrades to these old generators.
I was invited to present the benefits of generator upgrades at the most recent EPRI User’s Group meeting in Baltimore. The video here discusses the key points of that presentation.
Rotating Element Inspection
July 20, 2018
The rotating element of a Size 270 Dual Circuit Fluid Drive has been inspected, balanced and reassembled.
Technical Note: July 2018
July 19, 2018Are you getting 100,000 between overhauls?
Dr. Mel has released a Tech Note concerning fluid drives. TRI offers upgrades that can improve the fluid drive reliability. read more…
Thrust Bearing Spring Bed
March 13, 2018Each spring and cap are machined to precise tolerances in order to achieve a consistent reaction force across the thrust bearing surface.
Flush Cock Valves
August 25, 2017A video explaining the advantage of flush cock valves manufactured by TRI Transmission and Bearing Corp. has been published to YouTube.
When shafts rub
July 12, 2017It is undesirable to have a shaft to rub metal to metal with another machine components…but it happens. When it does, the question often asked is “Can the shaft be fixed?” It is easy enough to bring in an service that does field machining to fix the surface of the shaft, but the heat caused by a rub alters the shaft steel much like the heat affected zone that occurs during welding.
This video explains what happens with crystalline structures in steel when exposed to intense heat.
Below is a photo for a part that rubbed. Over 0.1″ has already been machined away and you can see the hard spot that still remains.
