Q:How to shut off the diesel generator

Emergency situations can press the emergency stop button can be forced to stop.

Q:I have noticed that many people leave their computers on all day for some reason. I would like to know why and if its better or worse for the computer than to just turn it off. Also, is it more efficient to leave it on?Anyway, the only thing I would like to know is why do many people leave their computers on all day and if you are one of them, why?

There are several reasons for this: 1) If it is an office computer and you are an administrator of some program, you need to keep it on so that other people can access it. In this case your computer is a server and servers are never switched off. 2) If it is in a LAN (usually but not strictly) in an office, there are some programs that run updates/scans, like antivirus virus etc. 3) If people are working on something big, they tend to lock the machines and resume work later on. Usually, it is best to restart the computer regularly. Even if you are keeping it on continuously, come later and before starting the work, restart it. Efficiency of a computer decreases if it is left on without proper air conditioning.

Q:i got 390 TONS OF REFRIGERATION OF PU,TOTAL 16 NO,HOW MUCH KW OR KVA REQUIRED DISEL GENERATOR TO RUN THIS ,PACKAGED UNIT, TOTAL LOAD IS 390 TR, PLS CONVERT N TELL ME,N TAKING FACTOR OF SAFETY ALSO TELL ME THE KVA OF GENERATOR

390 tons is equal to 390 x 12000BTU 4,680,000 BTU with this capacity you may consider a generator of 1 mega capacity this includes the factor of safety.

Q:im an helper mechanic and i ask my boss about it he didntgive me an answer so selfish of him !!!

Reverse power shutdown, can be caused by to low of a frequency or hertz setting,below 60hz., for example 30hz., or cycles.It also can be caused if several generators are on the same line, and one has a much lower output,It will shutdown or trip off on reverse power.Hope this helps

Q:If it is that equation then if i ran a 500 gallon diesel generator under full loadsaying at about 3.5MPG will i get 1250 hours to get 52 days?!?!?!? or am i off on equation or my theory????

Conversion? They are calculating two different things. The reason something would be measured in work hours instead of mileage is for the fact the equipment does not in fact travel under its own load or it spends more time at a stand still. Work hours tend to be used on a lot of construction equipment and other things that stay stationary for long amounts of time thus creating wear on the unit though it is not moving and adding miles so they use hours to calculate how old the unit is or when it needs to be serviced next. You can never get an actual equality from these two different units as one measures time usage/fuel and one measures distance/fuel if you were calculating to find a run time for example. ***additional*** There would be no equation for MPG that you are looking for if converting from hours. Are you looking for how much fuel is consumed over a length of time? That's the only way to calculate fuel consumption would be over time vs. over a distance as MPG is.

Q:Example 1:A GP38-2 has a 2000 HP prime mover diesel engine.What are the horsepower ratings of the electric motors geared to the axle? [4 electric motors; 1 on each axle how much HP?]Example 2:An SD38-2 has a 2000 HP prime mover diesel engine.What are the horsepower ratings of the electric motors geared to the axle? [6 electric motors; 1 on each axle how much HP?]I know the tractive effort of the SD unit would be higher, but with 2 more motors on the axles, does it have more horsepower also?

The short answer is, the horsepower is fixed. That is determined by the diesel engine and that can't make more power, it is just divided either by 4 or 6. A 3000 HP GP 40 locomotive pulls considerably more amperage than a 3000 HP SD 40, same horsepower divided by fewer axles, which is of course why the 6 axle pulls so much better at extended low speeds than 4 axles. The total horsepower stays the same, at full throttle the prime mover cant make anymore, your GP-38 will not be able to make any more power than an SD-38, both 2000. Added: At full throttle the main generator is putting out all the power it can, there can be no more load on it, that is fixed, the variable is the number of axles. Avio's figure of 750 HP per axle is absolutely correct, But those 750 HP motors in a 3000 HP locomotive obviously are never making over 500 HP each, there isnt enough power available from the main generator. That is why those motors last so much longer and are able to pull heavier loads, they are never making their maximum power. The amps we see on our meter in a locomotive dash is measured at the number 1 traction motor, not the generator/alternator output. At 10 MPH under maximum throttle a 3000 HP SD-40 (6 axles) pulls around 900 to 1000 amps (per axle), at the same speed a 3000 HP GP-40 (4 axles) locomotive is pulling well over 1200, heat buildup is a factor, short time ratings are soon exceeded and wheel slip is uncontrollable. Good question.

Q:I want to start my own business in industrial field i'm ready to invest money but i don't have qualifications like B-Tech, or any Degree or Diploma. I have completed my industrial training and i am working as a design engineer in small company. I can operate Auto CAD Unigraphics software and i can design anything (mechanical). I want to do business which helps to our eco system i.e. Acoustic Enclosures for Diesel Generators sets which makes a lot of noise and sounds etc etc.And ofcourse I have ideas about office system which will help to increase my business.I JUST WANT ADVISES WHICH CAN BE HELFUL FOR MY BUSINESS AND ME

Actually setup your own company is not necessary to have any professional qualification. I am not very sure is your this business needed? Most of the big hi-tech company director also not in their major study in U. Just go and do it as what you intend to do. Dont waste your time and wait here and there. I am doing accounting services but i am also not from this accounting background but i still go ahead and i have my own company now.

Q:if there is a website where you got it from, please put it in your answer.

It is an engine, not a motor. What size, and relative to what, for what use.

Q:gas is too expensive. here in florida i guess everyone has a noisy gas powered generator for when hurricanes knock out our power

Q:I'm a student majoring in Architecture one of my class, Building Utilities, needs me to survey a high rise building. In my team, we divided the parts bc there are so many and one of my job is to electricity. Can someone explain to me the meaning of phase, R.P.M, power factor, and (especially) their respective units/numbers from this picture

'Phase' has no units: it is merely a number, in this case 3. It is the number of different live supplies coming out of the generator. On the blue label in your picture, to the right of the word PHASE there is a small clear panel. The 3 followed by a greek letter 'phi' is the number of phases. Then there is '4 W'. This tells you that the generator is wired in 'star' layout with a total of four wires. Three carry the live supplies and one is a neutral wire. Your building will have a lot of wall outlets and some heavy loads; for example, the motors for the elevators. The wall outlets are single phase, connected to only one of the phases from the generator. Heavy loads are often connected to all three phases. 'R.P.M'. is revolutions per minute , which means 'how many times the rotating part of the generator rotates in one minute'. 'Power factor' again has no units. An explanation of what it is? I'll come back to that later (or someone else can) .
