600 Hp Snow Pipeline Compressor - Full Speed - Coolspring Power Museum

Engines like this were used to pressurize natural gas transmission pipelines. Pumping stations were located at intervals along each gas pipeline. Each station might have half a dozen of these engines, with extra capacity to shut down individual engines for maintenance. Normally, each engine would run continuously for months at a time.

This engine has 2 double acting cylinders, thus effectively a 4 cylinder engine. Watching the camshaft, you can see the firing order. Go to 4:37, and step forward frame by frame using the period key. The lower rocker is exhaust, the upper rocker is intake. Exhaust is open for the exhaust stroke, then closes at BDC, and the upper Intake valve opens immediately for the intake stroke. Both valves are closed for the compression and power strokes.

Speed of these big engines is limited by dynamic mass of the pistons and centripetal force on the flywheel. Thus this 600 Hp Snow with the bigger flywheel runs slightly slower than the 400. Similarly, the later 2 row engines can get by with a much smaller flywheel, thus run faster. My recollection is that the 600 runs approximately 90 RPM.

Something to think about, the Worthington Snow-Holly works must have had a lathe (VTM = vertical turning machine) big enough to turn these flywheels. The flywheel is in 2 halves, held together by "dogbones".

For a video showing some 400 Hp Snows, look for "(6) 400 HP Snow pumping engines Heath Pa". They ran considerably faster than this 600 Hp engine, about 120 RPM, due to smaller flywheels.

So soothing, listening to the sounds is like an orchestra.

[rodneyjweltham]

absolutely fantastic. The sound, spectacle and preserved for generations to come...

Many times i've come close to falling asleep to a late afternoon run of the Snow!

I love listening to the Snow engine. Still not sure what causes that distinctive 'tick-tick-tock-tick' coming from the valve set near the flywheel (not the ignitors, they're relatively quieter, ) but it just adds to the character of this beautiful machine. Would love to see her in person someday.

i own several of the worthington buildings where they built these engines . we have some old pictures on the wall .

[DiamondReo]

we have a similar engine at kinzers. cool to see it run

[blendpinexus]

ah, i was starting to think the pistons were double acting when i was watching the rockers and listening to the sound. and having two cylinders in a row? that's just impressive thinking for the limited engineering and machining they had

[jesseamaya]

I can easily see this beauty in the engine room of a massive starship traveling between galaxies. Keep in ming that I had several hard blows to the head, , , ,

For what though? What is gained by this?

See how fast you can get it going before part's patts start to take on wings before parts start to fly💣💣💣💣🔥🔥
