Wow that looks expensive!
http://forums.pelicanparts.com/uploa...1277923818.jpg I bet these are expensive too! |
Nuther one, this time the turbine ran waaay too fast and the gearbox 'ploded, sending the gears is various directions at relatively high velocities. Those crazy Filipinos:

no shear coupling?

In this case the load was exteremly low but the speed was a tad too high. The gererator tripped off-line, which basically eliminated the load. The governor valves were stuck with scale and did not move. The trip valve was also stuck and did not close. The turbine went from normal running speed to reeaaaaaalllllly fast in a couple of seconds. Imagine running your car at full throttle in 5th gear and pushing in the clutch without lifting. Then imagine you didn't have valves that would float and limit the rpm. Then imagine you didn't have an intake or exhaust system that would limit rpm. Instead you had an engine capable of accelllerating to rpm levels more than fast enough to make the engine go boom. That can be as low as 10,000 rpm for giant turbines or as fast at 150,000 rpm for smaller turbines. Checking their overspeed trip valve and governor once in a while might have been a good idea. Biggest steam turbine I ever overhauled was rated at 1,500,000 horsepower. Took quite a while and I couldn't do it all by myself. See that red-oxide colored thingamajig in the picture? that's it. The rotor was made in 5 different sections, the largest sections weighed 175 tons each. http://forums.pelicanparts.com/uploa...1277925460.jpg Here's a nuther picture of it. This one shows units 2 and 3. Fer perspective, the deck where the turbine sits and the rails where those 225 ton bridge cranes sit on are about 60 feet up in the air IIRC. http://forums.pelicanparts.com/uploa...1277925614.jpg It's kinda hard to find a close up picture, I guess they're just shy ;) |

And the funny thing is, right after you blow load you think "WTF am I doing! This is gonna cost in so so many ways..." But 15minutes later, your looking to tap that can one more time and forever! That package is the once and future end of man's sanity and we keep at it forever... |

I don't find that particular package attractive in the least - I can smell the b!tching, whining and gold-digging through my monitor.
Here's a much better example http://forums.pelicanparts.com/uploa...1277951083.jpg |
Now you are thinking like a sane married man, using your brain not your nads.
I totally agree with you! But still I enjoy the view of that rack. I can look from afar but I would never get close to them. |

Thank you for the wallpaper.

Another pelican is familiar with this pic. This is/was(hopefully) an architect's rendition of how to push a proposal for a oversized appartment building P.U.D. through the public planning works.
Notice that it is actually 5 storys tall. The building on the left is 3 storys, and the building on the right is 4 storys. http://forums.pelicanparts.com/uploa...1278002353.jpg |

Number 3 is my choice, very symmetrical. I liked that.
