Here are two pics I took at work recently. The first is a 7000hp electric motor used to drive a 6-throw reciprocating gas compressor.
 This second is of the bank of recips in this compressor building. There are (2) 7000 horse drivers with 6 throw compressors, and (2) 5000 horse drivers with 4 throw compressors.  Like a dumbass, I forgot to take pics of the other half of this building housing the three turbine driven centrifugal compressors.  |

Slightly off topic, and Im NOT trying to crap on your thread.
This thread makes me angry. nice engines......... but total fucking fail. Instead of some massive NG driven engines to pressurize NG lines, now we have a national NG system that is gradually working towards complete reliance on electric power (but is cleaner and safer for the environment!  ). So, when the electric power goes down, so too does our NG delivery system. This kind of inter-reliance makes us more vulnerable.

I've rewound several 200 HP electric motors years ago. I could climb inside the stator.
They were used to make "paper mush" that eventually became Pampers diapers. We used to test them with copper "no blows" in the disconnect...

I saw 3 of the biggest motors I've ever seen on a job a few weeks ago. If my memory is right, they were 13,200 volt, 590 amp and rated at 16,500 hp each. They were running pumps with 74" suction side and 60" discharge sides. I think the output was 3300 gal/sec. each and they push over 300' of head. I probably should have taken a picture.

Posted Via AR15.Com Mobile The highest/hour downtime rate I've heard is 250k/hr. The reason? It was a Bosch braking system plant that was ran by the UAW. The plant managers I was dealing with said well over half of that figure was due to labor agreements and wages. The plant shut down a few years ago. Bosch said enough is enough, moved all the production capabilities to a non-union plant. |

We have a 1.6mw cat running on landfill gas that could run 20 gas compressors. Only thing is there are no main NG lines run near enough for us without a big payout. If gas stays low for more than a few years there will be compressor stations all over like yours. Have you added order ant yet? Quoted:

IIRC from a previous post/topic a while ago, we can blame the EPA for this. Apparently the NG distribution system used to be pumped/pressurized by large NG powered engines, fueled by the NG they were pumping - eg a self-contained pumping station off in the boonies powered by the fuel it was pumping.

Slightly off topic, and Im NOT trying to crap on your thread. This thread makes me angry. nice engines......... but total fucking fail. Instead of some massive NG driven engines to pressurize NG lines, now we have a national NG system that is gradually working towards complete reliance on electric power (but is cleaner and safer for the environment! ). So, when the electric power goes down, so too does our NG delivery system. This kind of inter-reliance makes us more vulnerable.Total fucking fail is right, and it's your post that's full of it. 1) The turbines I mentioned not getting pics of? That's cause they're fucking hot right now. I wonder how they got that way? 2) Not sure where you got this reliant on electricity idea, but it's contrary to what I've seen. 3) Are you a commie? Forcing us to use a power source? Fuck off. We'll use whatever is economical. EPA comes along and fucks with the emissions from the NG engines, and now all those engines are being replaced by electric motors, as illustrated here. Where does the electricity come from? From a NG fueled power plant.
Talk about a circular equation. With EPA disappearing up their own assholes. WTF? The EPA has different regulations and penalties in different regions - which is one reason why gas turbines are still being used in some pumping stations. There may also be some "grandfathering in" of existing turbines. |

That'd run a heck of a sand blaster!

It will power one of those won't it? Probably not. But it may run the instrument panel and you would know for sure the driver wasn't turning.
And yes, we make some long jumps through tiny hoops to keep the EPA happy. Posted Via AR15.Com Mobile |

Cool stuff. Makes the chillers and equipment I work with look like toys that belong in a childs crib.
