Locomotive Air Compressor Died! We Gonna Change It Out Today

[@beverlymichael5830]

Gardner-Denver; I recall back in the 80’s the “compressor” that run off the P.T.O. of my Kenworth to charge the pneumatic trailer that I hauled bulk cement with, was a Gardner Denver. Not surprising that the compressor on your train engine was made by the same company. Noted for durability and longevity. It seemed they ran for years w/o problems

[@ccrx6700]

Thanks for watching and writing in. Who knows, this loco was built in 1978 and it could have been the original compressor. Really appreciate your stopping by and sharing my friend.

[@JasperFromMS]

I'm proud that you are respectful of your coworkers and I understand (but am disappointed) that they don't want to appear on camera. Please extend my thanks for their work, and yours. You all keep the trains safe on the tracks. Since the trains are safe, and running, the coal gets moved. The guys in mine depend on you to move the coal that they mine. They can't work if you aren't good at your job. And needless to say, we all get cold and dark. So again, please express my thanks and admiration for a job well done.

In terms of size alone, that baby is one big compressor. I`m used to working with things that put out 9, 10, 11, 13 cubic feet per minute. And for my application, a 13 cfm compressor is a beautiful thing. This baby puts out 254 cfm (as per Dave`s info in the description). Man, that`s a lot of compressed air. Pretty cool stuff, Dave. Thanks for putting this together, and for the detailed info in the description !

Wow Dennis, what a very nice comment. So glad you liked this one. Really appreciate your taking the time to watch and write in my friend.

[@brianhickey5949]

That is a reciprocating air compressor (looked it up at Gardner Denver) and so that means positive displacement. Now, when we hear the relief(s) let go, we know that the engine is releasing excess pressure from the system. So anytime the engine crankshaft is turning, the compressor is running. I guess that makes sense - we need the air for the brakes on the entire train. Thanks for this look inside engine 22! Very cool to get the detailed low-down even it the air compressor had to die to let us see it :)

[@ccrx6700]

Even tho it died on us, it will be resurrected for a new life in another loco somewhere. There is something about how the valves work in it so that when 140 pressure is obtained in the main air reservoir, the compressor is still turning but no air is being compressed. Can't thank you enough for taking in the home movie today and writing in my friend.

[@brianhickey5949]

@@ccrx6700 The engineer in me is now very interested :) Piston positive displacement running continuously means as you say, the valves must do something to relieve the potential overpressure to the MR. I began a search, but so far I am finding overviews and no details. We have HiPACs on submarines (4000 psi air) but they use a regulator to shut the compressor off when the correct pressure is reached. LOL! Full geek mode now - apologies!

[@ccrx6700]

@@brianhickey5949 😊👍

[@mikefochtman7164]

@@brianhickey5949 Those small lines leading to the tops of some of the pistons look a lot like 'unloader lines'. Oil pressure applied in them will shift the top valves so they can't close. With them 'unloaded' those pistons move up and down but the same air just stays in the cylinder. Common on larger compressors, so while it runs at one speed, when the outlet pressure rises enough, it can 'unload' some of the cylinders and basically become 'half a compressor', moving half as much air. Still need the reliefs on the reservoir, but with less air pumping, things are a bit easier.

[@bluegrassman3040]

The dash 8 and newer GE/Wabtech engines have electric air compressors. They only kick on when air pressure drops to whatever psi it’s set to kick on at. They also start up unloaded for a few seconds then load up to increase service life of the electric motor. The electric motor can increase rpm if needed. Those are compressors all have that distinctive “whoop” sound.

[@DarkVoidIII]

That looks like a lot of air to compress! They need it all, got to have sufficient pressure to stop many wagons. That's a lot of air to supply! Thank you for showing it to us! Looks like that has a water bleed valve fitted to it, if the water vapor buildup wasn't removed, there wouldn't be space for the air in the air tanks, and it would show as lack of pressure. The compressor has to supply sufficient air to push out all of the water vapor. A railroad worker told me once that the engine was capable of pushing out enough water vapor buildup if the water level was below the intake side of the air tank. They use either a cyclical dump valve or a constant drip valve. The latter will just drip water vapor out constantly, the former will just cycle, as the description says.

[@ccrx6700]

Yes it does take a lot of air, and here besides the brake system, we use air to dump our hopper cars. The cycle valves you are referring to are called spitter valves. We have them on all of our locos, plumbed into both main air reservoirs. In theory they sound good, but in reality they don't work very well. On pre op each operator manually opens a valve on the MR's and lets water escape via those valves, it is amazing how much water sometimes comes out. Thanks so much for watching and writing in today my good man.

[@troubleshooter1975]

I couldn't see it. With his close shots (and my lack of knowledge), I couldn't see where the air goes. Is that the MR tank above the drive shaft? Can you time stamp where this valve is visible?

I had never seen such a thing before, and had it not been for your video I probably would have never seen it. With all the hours these compressors run, it's amazing this repair isn't more common. I also had no idea they were water cooled. You probably have to use the little guy to get in between there to separate the shaft fasteners. Not a lot of room in between. I did not know you could advance the crankshaft manually. That is a neat tool. Reading the description that was a Yankeetown Dock locomotive. I got to see her there in the early 80's along with all the FM units they used to have. This locomotive was paired with #21 and the staff allowed me to move the pair out of the way just so we could get better photos of the FM units. I was put in the seat and shown what to do. even though we only moved a few car lengths, this was a thrill I will never forget. The Company and employees were so nice to us railfans and all we had to do was sign a waiver to be on the property and told to be careful and alert. My favorite was #20, the Can Do America paint scheme, it was so cool back then. Thanks for sharing. Cheers Rob

When I look at the old power plants with hundreds of switches and gauges and lights and buttons and people know exactly what every single one of them does and that's truly amazing and there's not many people that know how things work anymore. I see so many people break so many things because they have no clue what they're doing I just had a mechanic break two bolts on my caliper because he didn't know what he was doing so now I have no car and have to have it towed to a garage and spend a lot more money to get it fixed and hope to God they know what they're doing Before I got sick and bedridden I used to do all the repairs myself I hate relying on other people to do work because most of them don't know what they're doing

[@brucepaul6251]

So on this compressor, are the outer heads the low pressure heads and they discharge into the center head which is the high pressure head that discharges into the train air ? I think Gardner-Denver bought the designs from Joy Manufacturing which also made this type of compressor. The nice thing about this design is that it probably has the Load/Unload feature which draws less power when compressed air is not needed by the braking system. Working on this type of compressor can be tricky, especially when doing valve work. Thanks Dave for a great video.

[@gravelydon7072]

That is the normal way they are set up. The outer cylinders are a larger diameter and the inner ones are smaller. That puts about the about the same load on the crank journals instead of just using a piston to go directly to the high pressure. Which on that loco is likely to be in the 150PSI range. So you get both volume and pressure. The intercooler takes the pressure from the lower pressure pressure cylinders and cools it before sending it to the high pressure cylinders which helps with a longer life of the compressor and the oil that lubes it. The lube on these is fed under pressure also. G-D has been around for a long time.

[@ccrx6700]

Good question Bruce, I am not familiar enough with the internal workings to answer your questions. However here is a good comment you may enjoy reading from a diesel mechanic www.quora.com/How-does-a-diesel-locomotive-railway-compressor-work-and-what-is-its-draft-valve-principle

[@mikefochtman7164]

I'd say so. Looks like it might be two first-stage pistons on each side, feeding that inter-cooler on the side which then flows into the center cylinders. Cooling between stages improves efficiency. And with twice as many first stages feeding the second stage cylinders, you get good compression ratios between stages without having to go with wildly different cylinder sizes.

[@troubleshooter1975]

@@mikefochtman7164 I agree, it is already two to one ratio. That being said, at the crank case, where the cylinders bolt on (under the water jacket bulge), the outer banks do appear to be slightly bigger, maybe 20%? [around 0:35 for example]

Yeah if you want to know where it got hot. it's where all the grease and paint are burned off. That thing got really hot! Learned something too. I always assumed the compressors were electrically driven. Never expected to see a direct drive, not even a clutch. It just runs all the time.

[@ccrx6700]

Glad you enjoyed the show today. I'm not familiar with the internal parts of it, however the drive shaft as you say keeps it turning all the time. When main air reservoir pressure is met at 140 then it stops compressing air, so no clue what goes on inside the compressor to make that happen. It's not like a 220 electrical compressor where the power is simply shut off. Did some research and this is a pretty good explanation of what happens once the 140 pressure is met, it's the first comment on that page by Edward Rush. Glad you brought up that point because I learned something new from it www.quora.com/How-does-a-diesel-locomotive-railway-compressor-work-and-what-is-its-draft-valve-principle

Your certainly welcome Big Don. To do a video on the air and everywhere it goes would be an immense one and I'm not knowledgable enough to be 100% accurate on every single thing in the pneumatic system, although I could do an over view. There are a ton of valves involved in their entire system and ours is even more complicated because the remote system is plumbed with air also. Will keep the suggestion in mind for a future video tho.

[@TheBeeMan1994]

Is there a shear key in the shaft of the air compressor? so if the compressor locks up it doesn’t cause damage to the locomotive or the prime mover? I was told at the RR I work for, the mechanic said years ago one locked up in route somehow on a GP35 and it ripped the compressor off the floor and was spinning the compressor around in the car body, but I’m not sure if I believe that lol

[@ccrx6700]

No Andrew there is not. It seems a bit far fetched that it would tear the compressor from it's floor mount and even if it did I highly doubt there was room enough for that big compressor to spin 360, but then again on a GP35 the compressor could be smaller, I do not know. What I would think is more likely the thru bolts would shear or the drive shaft itself get ripped in two. But strange things happen all the time on the RR.

I just assumed upon looking at those holes on the compressor flange; that they have 'extra' bumps vs a flat flange with drilled holes, and I was assuming those were rubber inserts/mounting spools (like end of an auto shock absorber, rigid center thimble/sleeve). around 1:24 Either that or clearanced metal to metal to allow some play...
