1897 Robb Armstrong Steam Engine
Вставка

- Operating a beautifully restored Robb-Armstrong stationary steam engine. Built in 1897 in Amherst, Nova Scotia, the Armstrong develops 130 horsepower and just over 3400 foot pounds torque at 200 RPM. Cylinder measurements are stated as 12 inches of bore and 12 inches of stroke. This engine utilized a cutoff governor located inside it's flywheel to regulate engine speed by varying the valve events through the use of a centrifugal weight acting upon a moveable eccentric. This engine spent it's working life operating a refrigeration compressor, which it continues to turn to this day in retirement. The ammonia compressor was built by The York Manufacturing Company of York, Pennsylvania. Filmed at Pioneer Acres Museum, Irricana, Alberta.

Only 130 horse, but over 3400 torques. Good fun.
Rainhill1829 Gotta have my torques
Who says torque is cheap ? I have sawn 18” plus logs with a 12 BHP Robey portable Engine. Oh man how we used to love to hear that engine bark when it came under load.
And being a steam engine, it makes all that torque at zero rpm.

I often get confused by such things, then I remember you have to divide by 5252 ( or you can just remember 5200, close enough for off the cuff math. Very roughly 3000*200/5200=6000/52; even more roughly 600/5=120 HP. If I did the math for real, I would get 130 HP. Which means HP is all about RPM. Which is why a formula one car, with a small displacement, makes a ton of HP, as it runs at a stupidly high RPM, 18000 maybe or more. A steam engine will long outlast an F1 engine though, which needs frequent rebuilds :)
Every time I see these great old engines, I feel that I was born in the wrong era. Nice machine for sure.
@Allen Manseri Just love old rusty iron.
THAT is a well oiled machine. Very satisfying.
She runs great for over 120 years old.
Thank you so much for seeing this engine working and intact. A wonderful sight.
No problem, happy to help.
The Steamboy theme? Ha! Awesome! I kept thinking of it when I was watching this video and the Rumley Oil Pull video. Thanks for publishing these videos! It's great to see these old engines in motion.
Yes, I love that movies soundtrack, thanks so much for watching.
That is a thing of beauty.
Indeed
Low RPMs but lots of torque for sure. I like seeing this. Thumbs Up!
Thanks so much.
I can appreciate the steamboy soundtrack at the beggining. Well done.
Thanks so much, not many folks know of that movie.
@@Rainhill1829 fantastic movie. Probably watched it a dozen times already haha
I know where 2 engines similar to that one is out on an old oil lease I operate, I've been wanting to haul them out and restore them, the bull bearing is out on the big one and it wore thru the race, but a machine shop can bore it and machine a sleeve for a new bearing, it would be a cool project to start
Thanks for sharing, that's a beauty 😊
Nice
Brilliant video, great to see this beauty in motion. Regards from Ireland.
Thanks so much, cheers from Canada.
que maquinas mas espectaculares son toda una ingenieria
Must have amazing skin with the wood resin and the steam!
Very great 👍
Building I lived in, in NY City once had (4) 1200 hp Corliss engines in the basement to run the Broadway cable line line starting in 1894. They were powered by 12 high pressure Heine boilers, everything had been removed and scrapped except 3 boilers, 2 of them used for building heat the 3rd one was against the wall and kind of hemmed in by the other 2 so it was left, it still had it's original coal grates, the other 2 were converted to oil fired. There was a 32' driving drum too, what a shame it was all destroyed probably by 1905 when due to so many problems they electrified the line instead.
I was able to find a few photos of the engine room
amaizing
Do you have any idea of the steam temperature and pressure? Also, does it exhaust to a condenser?
I would love to have one to run my home work shop, and would love to see the blueprints for this beast
I wish I could find them, their bound to be out there somewhere.
Blueprints are the least of the difficulties, imagine wanting to replicate one of these how much it would cost to make all the patterns, sand mold, cast tons of cast iron parts, then machine them and assemble!
Try looking at the patents. They will likely lead you to a trail that will help you find the blueprints. That is what I did to find the blueprints for mine.
Of course, I lack foundry expertise so I would highly suggest hiring out the cast iron parts and machine them yourself.
What am I saying, you'd already know what you are capable of. Anyway, good luck! Im hoping to have my lineshaft steam shop done in a couple years.
What is the origin of the vertical boiler?
It looks like a crane boiler, from a fairly big crane/derrick. I know of some Clyde steam cranes on the Great Lakes that were converted to diesel, perhaps from one of them?
Great stuff!
Well done, this boiler was built in 1948 by the Browning Crane and Shovel Co. of Cleveland, Ohio. It spent it's life in Canada operating as a boiler for a railroad wrecking crane on the Canadian Pacific. At some point the boiler was separated and sadly is all that remains of the whole machine, probably as part of a repowering project or it simply was phased out by diesel machines. The museum adopted it and built the building around it to power our stationary steam exhibit. Thanks so much for watching, glad you enjoyed.
What are they firing?The boiler on? Coal?
How long would the engine run once it was up to steam? Does it need a continuous fuel supply to move the piston?
Was it set up for a commercial refrigeration operation?
That thing was built to last. Thanks
This unit did run a commercial ammonia refrigeration compressor, once it was operating it would very likely run for weeks or even months with very little down time. Lubrication was automatic and the only wearing item that would require a sop of the engine to service would be the piston packing gland, either for tightening or replacement, both of which are quick operations. The fuel supply would be continuous to the boiler, but it would have been used for many other processes as well so it needed to operate full time. It either ran off coal or possibly coal gas from a local supplier.
It runs surprisingly quiet! I also noticed the belt is crossed, something they used to do for better driving stability and efficiency. However nowadays belts are considered inefficient drivers. I wonder what material it is. It looks like some kind of rubberized fabric.
You got it, its a canvas woven belt with a vulcanized rubber core.
Isn’t it just to invierte rotation?
Great video's! :)
Thanks, glad you enjoyed.
How I like to look at this mechanism.
So does the The ammonia compressor still work? as in actually still compress Ammonia ? or is it just for show ?
As it is right now it only freewheels, the cylinder's are open to atmosphere.
Thanks for answering.
What is the function of the leaf-spring assembly that's part of the flywheel?
Balance?maebe
Governor
@@hotpuppy1 Thanks.
I can't help but wonder why you would run a belt like that crossed over. It must wear out much faster and couldn't you easily change the engine to run in reverse? I'm sure there is a great reason. I'd love to know what it is!
Crossing the belt gave a slightly higher belt coverage for both pulley's which decreased slippage and belt wear, also the belts sliding past one another in the middle absorbed uneven vibrations and prevented "belt slap" that occurs during strait belt operations. Hope this explains a bit. Cheers.
@@Rainhill1829 yes, thanks!
The direction the engine is running the way it is is called "Running Over" if it where to run the other direction, that would be "Running Under" which would put more wear on the crosshead.
@@kpkndusa Yeah but back when this was built they could order a new replacement part for probably $25 in stock ready to ship, now it would cost thousands.
Does the compressor continue to refrigerate?
Not anymore, since it uses ammonia as a working fluid we decided not to charge it for safety and such.
Can I produce up to 200kw if I attach it to a pmg alternator low rpm. For electricity production. What is the average price of this machine today.
Im afraid this engine is only rated at 130hp and would need to be 280 to develop 200kw electrical, also its almost impossible to price it as it is over 120 years old.
Good display! How do I get a steam engine?
Just have to keep looking anywhere you can, they can be tough to find now.
Why the reverse belt? Compressors typically are not sensitive to rotation direction. The belt is being destroyed. Cheers.
The crossed belt has a twofold use; first and most important it prevents “belt slap” caused by slight variances in power and load which setup a standing wave in the belt causing it to fall off the pulleys or snap. The second reason is crossing the belt causes more of the belt to engage the pulleys surface, allowing more power to be transmitted without slippage. Hope this explains it, we fo need to change thus belt its getting a bit frayed, probably next season.
It's not running anywhere near 200 RPM though. I count about one revolution per second so about 60 RPM. 200 RPM would be more than 3 revolutions per second which would really be a sight to see. I guess they don't want to stress it and risk breaking things.
You are right on the money. Normally we only run it at bare idle speed, we have spooled it up to full power a couple times in the past but it developed a slight knock so we prefer to go easy on it.
What was this engine used for? Trains? Old ships?
This one ran a refrigeration compressor at a factory.
Why do you cross the belt? Steam engines run in either direction.
how. many. H. P. engine. sir
Human mind turn on first machinery time steam engine
I am salute our world engineer
I am Indian organic farmer
200 PSI?
We only run them 125-150.
What are the spring and weight for inside the pulley
That is the governor, at full speed it would change the motion of the eccentric moving the valve. The throttle could then be left wide open and under light loads the steam going into the cylinder gets cut off early and the steam in the cylinder expands for the rest of the stroke. It is more efficient then controlling the speed with the throttle.
Note that during this video the engine is running about 1/10 the speed it would when it was working.
I thought it was the governor but I didn't see any linkage to anything so I wasn't sure since I haven't seen a set up like that in person
That's right, you nailed it. This flywheel governor acts on the steam chest valve eccentric right next to the flywheel and varies cutoff by moving the eccentric closer to the crankshaft centerline and reducing steam flow to the power cylinder, simple yet effective.
Automatic Timing ! Wow
Looks like you could use a new rubber band.

Up
200RPM's LOW AND SLOW
mechanic world has
That crossed belt is a unhappy solution.... it loos so worn...
Yeah, it’ll be up for refurbishment pretty quick here.
The steam engine is great! But the boiler needs to be changed,
I don’t have any smoke from coal on the boiler,
but here the smoke is on wood.
Игорь Михеенко It is actually a coal boiler with coal grates in the firebox, we just run it on wood because its easier to handle in the building.
@@Rainhill1829 Look at my coal boilers. My boilers emit cleaner gases on coal than gas boilers.
Coal consumption is half as much. I am looking for a companion for joint production and sale,
but so far I have not found anyone. No one needs clean technology in our country.
Thn sakmono tik ws ono lewis
Seems very slow rpm..like 10
I would have opened up the throttle a little but more than that to break her in and put it through it paces on a saw mill and run it at least a 1000 rpm
We occasionally run it up to the point the governor takes over but it begins to develop a knock in one of the crankshaft bearings when we push it hard, so we don't do it often.
Slecht voor het milieu
Lambat macam siput 🙄🙄🙄
Is so quite. Nice engine. Remove the ending so we don't have to see that dorky looking guy with the dumb hat and on top of that acting so stupid.
That's five minutes of my life I won't get back....
Zzzzz
So boring, that speed is not enough to do a task, please get the revolutions like a formula1 engine until 19,000 rpm 😵😵😵😵😵
This steam engine has very high torque that can pull off a lot of work.
Car engines cant do shit without gears.
CO2…oh no
Nice
Thank ya.👍
