@Andy_Jee 2 года назад

These old machines are impressive they can handle such poor quality maintenance practice and still somehow work... Some white metal bearing tips: - For high reliability installations they need to be checked for cracks (dye pen) and check the bond of the white metal to the bearing housing (UT) - Always measure the journal and bearing and verify the clearance is correct, this ensures a proper oil wedge will be formed. - Lightly hand polish the bearing and journal if there are surface imperfections - CLEAN everything before install - if you need a hammer during disassembly or reassembly you are doing it wrong. - Avoid filing or polishing during assembly or the bearing will be contaminated.

@kls2020 7 месяцев назад

"These old machines are impressive they can handle such poor quality maintenance practice and still somehow work..." This is the quote of the entire comment section . Chris reminds me of a management employee at a company I used to work for who came into the powerhouse during maintenance and asked the crew where the "Licket Gates" were located on the Generator. (Laughter ensued)

@Physicsduck 6 месяцев назад

You speak like someone who actually knows what's going on. THANK YOU! :) I like it when smart people come in and teach intelligent things. I'm not a Millbilly, so I really don't know much about the mechanical side of things in here.

@ichbinwiederda100 Месяц назад

Yes, but this is not a Diesel engine. That old thing is not that high load compared to size. Do a good dimension and shape check and do an optical check. And yes, keep it clean and use good practice wile passably.

just came back after my intern at Nepal's largest hydropower plant 456MWupper tamakoshi. and all i can say is that countries worldwide are really blessed that their water dont have sediment particles as nepal has.

@Physicsduck 6 месяцев назад

Oh I totally want to hear the whole story on this one.

@mikea5923 2 месяца назад

Lots of places have sediment problems. I’ve worked on many lake and River fed municipal water systems. Sand (and zebra muscles) is a common hurdle. This is almost always solved with by adding chemical flocculants and settling tanks. The tanks have sweeps on the bottom to collect and remove whatever the flocculants sink, mostly sand and clay.

@paulyates1682 2 года назад

Oh my god, it unbelievable that this is the quality of maintenance this machine is getting. Wow

Some BOZO beat the face of the shaft with a 50lb. sledge hammer and swelled out the top of the journal in a few places! Those bearings only have about 1.2 thousandths per inch of diameter clearance! Not a very clean work area either. Amazing it runs. Very interesting video though! Thank you for risking being injured to make this video. We all appreciate it.

@BigA1 2 месяца назад

As an Electronics Engineer, I didn't think I liked large electromechanical pieces of equipment - but that looks like fun stuff. Would like an explabation of what the various things were and did. For example do those big wires at the top carry power to the energising magnet, how much current do they pass? What's the mercury switch used for? How old is the equipment? Where was it manufactured and by what company etc etc.

@thegardenofeatin5965 3 месяца назад

There is something fascinating about these videos. I'm several different flavors of shop guy, I've variously worked as a carpenter, auto mechanic and aircraft mechanic, there are some rhythms I recognize here. I have no idea how to ask to get started toward having any of these guys' jobs. I was a member of a makerspace, another one of the members was a pipe fitter. He once mentioned that it's hard to find young pipe fitters. I told him it wasn't ever presented to me as an option. There's no path to go from being a high school student to being a pipe fitter anymore.

@dustin4028 2 месяца назад

there are definitely ways to get into all of these trades. but you gotta seek them out. You go to an apprenticeship. that's like one of the few ways. find an apprenticeship, apply, take the test, get hired, complete the apprenticeship. depending on the area and the system, a lot of these jobs pay over 6 figures so theirs lots of applicants for only a few positions that hire like once every 4 years.

@racookster Год назад

I just discovered these videos, and I'm fascinated! I've watched three. I guess this is about a large as a hydroelectric dam can be and still be maintained by grubby guys using hand-operated chain fall hoists and files and so on. Any larger, and you'd be needing some seriously heavy industrial tools. Any smaller, and it wouldn't be scary as fuck (which it is). I don't even know where this dam is yet, but I'm about to try to find out. This channel is wonderful!

@Physicsduck 6 месяцев назад

Thank you! I'm glad you're enjoying the series! We're located in Northern Michigan.

I think the bearing metal is called white metal. Or a PM metal bearing. It floats on a layer of oil. Because of its mass.

Pour a quart of Lucas oil on that bearing and it would last indefinitely. Not sure how it works but it can seriously revive even pretty far gone bearings. Add molybdenum disulfide and it'll probably never wear out 😁❤

@davidbudka1298 2 года назад

I could imagine if there is too much oil in the thrust bearing a fire could start and destroy the generator. I think that happened at Barneston, Nebraska in the early 1980s causing the plant’s permanent shut down.

@Physicsduck 6 месяцев назад

I would so love to know the whole story on this one.

@davidbudka1298 6 месяцев назад

@@Physicsduck what I know of the story is that the Norris Public Power District refurbished the dam and power plant only to have the one generator catch fire a year or two after. The power plant, being of only 0.8-Megawatts capacity in two units was then considered too costly to repair. The powerhouse is now a home. The dam had been built in 1922 by the Beatrice Power Company.

@bobthedog123456 2 года назад

Babbitt is normally cast in place so it wouldn't be a billet Babbitt bearing. Also photos of the wrench?

@Cragified 2 года назад

Can be. Doesn't mean has to be you can cut a bearing out of a billet of babbitt. All Babbitt means is it is a (1) high-tin alloys with small quantities of antimony and copper; (2) high-lead alloys containing antimony, arsenic, and tin; and (3) intermediate tin-lead alloys with antimony and copper. The hard metals support the softer metals against the forces and the softer metals allow dirt and debris to embed themselves and not run around the race like it would if made of straight steel. The name comes from the metallurgist Issac Babbitt that came up with them for steam engines.

@Physicsduck 6 месяцев назад

Doesn't the fact that it's made from a single monolithic piece make it Billet? Even if cast, it's still Billet. Most Billets start out as Castings originally.
