@Att Att Virtually all medium to large size diesel generator sets these days have turbochargers. It allows getting more power from a physically smaller engine, and also has some efficiency benefits. Boost is proportional to the load on the generator, the more load there is, the more fuel is injected, resulting in more exhaust pressure, which spools up the turbo, creating more boost pressure.
I did some contracting work in a Cummins facility and saw their backup generator room. They have something like 10 of these that kick on at once. It's fucking impressive. When the power company gets over 15 cents per kwh they can produce their own power with these cheaper. The whole friggin' plant runs on these.
Diesels run more efficient not just at higher revs but also under load. Idling in a motor like this will cause wetstacking. Not to mention gen wont function.
If the tech had have shut it off properly using the start/stop button and not the on off switch it would have idled for two minutes at 750 rpm before shutting off to allow the turbos to cool/slow down.
Thank you for bringing us this excellent and very informative video presentation which is very much appreciated by the people. The sound of this is magnificent, it looks good and is very useful for organisations that rely on a constant supply of electricity such as hospitals and correctional facilities. The community would always feel confident knowing that they have such an excellent piece of machinery, especially with the reputation for reliability that Cummins diesel engines have. You are to be congratulated for providing us with this video.
I love the smell of diesel in the morning. You know, one time we had a power outage, for 12 hours. When it was all over, I walked up. We didn't find one of 'em, not one stinkin' solar panel. The smell, you know that diesel exhaust smell? The whole hill. Smelled like... power.
Used to do parts for gen sets and fire pumps, MTU’s, John Deere’s, Detroit’s and Cummings, Wakashas, Atlas and Allis Chalmers and many others...miss that job.
Good to hear they worked as intended! Losing power at a hospital is always a scary situation, which is why they rely on backup generators to keep them up and running.
I work on these every day so why am I watching this? 😊. Very good bit of kit apart from that horrid PCC3200 controller. I'd ditch that in an instant if it were mine.
Is it common on a Cummins for the crankcase vent to be just open to atmosphere but located UNDER the unit? Ours at work were and it wound up coating everything from that point up to and including the radiator with an oily goo....
Yes, this is a common configuration for diesel generator sets "as shipped" from the factory. The solution is to purchase and install either a "crankvent" system which is pretty much a big can with metal filtration to catch the oil mist (which you dump out periodically), or install a system which captures the mist from the crankcase vent hose, filters it, and then puts the filtered air back into the engine air intake system - - while draining the captured oil back into the engine sump. The first system is pretty cheap (a few hundred dollars), the second is pretty expensive (many thousands). The REALLY cheap option is to extend the crankcase vent tube with long rubber hosing to the outside of the building and let it vent to the outside.
Klok cumins mah memang keren, saya sudah pasang intalasinya yang 2000 , sama 1500 KVA .. Sudah ada berapa mesin cumins aja yang sudah saya pasang instalasinya
I want to use that for my electric bike. Can I put the 1500 kW Diesel Generator on a bike trailer and use it instead of batteries? How much does it weigh?
help pliz i have got a 1500kva cummins same as above its oozing oil through the breather pipe as soon as it passes 80% load about 5 liters in an hour but anything below 80% no oil oozing out
Roly Fisher you can power an antire building with this Generator, i just recently powerd an entire shopping mall with this same exact model- entire shopping center! There transformer blew so they needed temporary power
How many hrs dose a gallon last in a full capacity in this machine? Can it reliably run 24/7 without breaking down? I need it for overseas business I want to know more about reliability, endurance and low maintenance information, and fuel usage about it?
that Cummins big machine 1500kW genset, engine power will be like 1600-1700kW, the fuel consumption will be about 100+ US Gal per hour in full capacity. differernt models designed for different applications, you want 24/7, then choose the right model, generally a genset is capable for 24/7 running at 70-90% of its rated power, depends on engines
This has 3 primary, 3 secondary spin ons, and ours we took it one step further and put 3 more raycore filters in between the primary and secondary for a total of 9 with a one inch supply fuel hose and minimum half inch return. Voids a 800 gallon external fuel tank running balls in under 8 hours
This unit’s probably 24-28k lbs dry, depending on spec. The biggest units run a 95L and will get up to 70k lbs, slap an enclosure on there and they can be pretty hard to move around haha.
We film these load bank tests after completion of a 4 hour load test, which we perform on every unit. So, at the time of filming, the engines are already warm!
@Ralph W in Africa? It's either scrapped for parts, sitting somewhere or running on it's last breath. If it's running i bet that the fuel and oil filters are the same ones you put on it years ago.
