- Q: I recently purchased a portable generator that is 7 hp and 3050 continuous watts, i tried to calculate the efficiency as follows:743 watts 1 hp7 X 743 5201 watts, (so at 100 percent efficiency, 5201 watts is possible to produce from a 7 hp generator.)the unit produces 3050 watts, so the 5201 watts (possible watts)/3050(actually produced watts) (0.5864) or approximately 59% efficiency, this does not seem right, it should be about half that.What am i doing wrong?
- That is correct, but it measures efficiency from mechanical output of the engine to electrical output. It does NOT include the efficiency from gasoline (or diesel) fuel all the way to electricity. You need additional information to get that, such as gallons per hour or per day used by engine when operating at full output.
- Q: I'm a salesman for a welding supplies company, and a customer is interested in buying a diesel welder/generator for use in the paddock where he can't get electricity. While looking around I've come across a 200amp machine but it says it's a 200amp AC welder. it was my understanding that all welders are DC standard, and the AC current was only on welders to weld aluminum.
- DC is desirable, but not necessary for stick welding steels. DC produces deeper penetration in most cases. However AC can be used for stick welding just as well. AC is actually better when welding with E7024 rods. AC welders tend to be very robust because they're incredibly simple, basically just a x-former or alternator, a large rheostat, and an overload protector. DC systems are a bit more complicated. Fortunately, the machine in question seems to have 110V 15A outlets for residential-type power, in addition to the welding outlets, which are 75 volts on open circuit. Machines used for stick welding are of the constant current (CC) type. That means that the applied voltage will vary based on the resistance in the arc. Note that MIG welding uses Constant Voltage (CV.) (The current in MIG welding largely depends on the wire feed rate.) Residential current outlets also need to be constant voltage, not CC. How much welding experience do you have? A year or less? With due respect, perhaps you ought to be asking some of your customers for advice, not GIVING it to them.
- Q: I want to run the generator just enough to feedback enough kilowatts to make my annual bill zero usage.
- I'm not sure what you have in mind is a good idea. If you mean hook up a gas-powered generator, that will almost certainly be more expensive than grid electricity, and worse for the environment. Where I live in California, it is impossible to pay zero to the electric company while connected to the grid, that's just the way the program works. We are billed a minimum usage of 1 kWh a day, whether we use it or not. Also, having a gas generator ultimately tying back to the grid would classify me as a small generator, and require an agreement with the power company similar to the one I have for solar alone. I don't know what the rules are where you're located, but maybe they follow a similar philosophy? EDIT: okay, I see now. At least for my system, the entire system must be approved as a whole. If I want to alter the system, even by adding a couple panels, I'm supposed to notify the power company. Also, where I live, solar is treated differently from other forms of generation. Solar qualifies for net metering. If I wanted to be a small generator from (say) hydro, my output would be bought at a paltry rate, not even exchange at the same price that I buy at. Your hybrid system, with the generator rectified into DC then passed through your grid-tied inverter, might fall under the same classification, depending on where you live. Also check your inverter warranty to see if it might be voided by connecting to a diesel generator.
- Q: I recently purchased a book on how to make a hydrogen generator that mentions either gas or diesel. However common sense tells me that a diesel engine requires some sort of lubrication such as cooking oil etc. I have tried to send a email but cannot get an answer. Does anyone out there know if hydrogen will work in a diesel engine without burning the valves out quickly.
- I'd suggest that you learn how a diesel works before you damage something. Note that the fuel is only introduced into the combustion chamber at the top of the compression stroke. They do this on purpose, because if any sort of fuel gas was in the cylinder during the compression stroke it would detonate before the piston reached the top of its stroke. This happens frequently enough in a regular gasoline engine to have a name: engine knock, and it wrecks the engine. Note that the 'cooking oil' you speak of is not there to lubricate the engine: it's the fuel. The lubrication is provided by the motor oil in the crankcase, and I do hope you've changed yours lately.
- Q: I just purchased a miller big blue 400D diesel dc welder generator . I will be using 7018 rods. There are two controls on this unit, amps and volts, for best welding results, what is the best setting? I understand that metal thickness will change this this, but I' ll be starting on 1/4 plate. Any help will be appreciated.
- I don't remember, but the best thing to do is test it. Get some stock that's not worth anything, then do some test welds. Every machine is different, even if I knew the settings for a similar machine, that doesn't mean they would be right for you and your machine. I like to weld a little hotter and faster than most people, so I would be at a higher setting than you might like. Some people like to to colder and slower.
- Q: If a 13L big diesel engine can produce 400 hp at 1800 rpm, and a 7L diesel can produce 400 hp at 3600 rpm, but the 13L produces twice the torque, which would produce more electricity?
- The 13L would produce more electricity.The smaller generator has to work almost twice as hard to do the same job. Torque is a measure of the turning force on an object such as a bolt or a flywheel. For example, pushing or pulling the handle of a wrench connected to a nut or bolt produces a torque (turning force) that loosens or tightens the nut or bolt. Also the higher the RPM the hard the generator has to work to get to 400hp so your 13L at 3600 RPM would produce around 750 Hp
- 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?
- i leave my computer on 24/7 cause if you keep turning it on or off it is likely that your data maybe lost or one of your components might fail.
- Q: Do they look any different? I can not see the difference and I do not know which trains are electric and which ones are diesel. If there is any difference in appearance, what is the difference?
- First off, all trains are electric, the only reason there is a diesel engine is to run a huge generator that supplies electricity for locomotive. but in a straight electric, first you would notice it is quiet and smoke free, no diesel egnines running. Second it has to have a way of getting electrictity to the motors while on the move, the most common and effective way is with overhead wires, the track will have lines directly over the center, and th elocomotives will have a device mounted on top that pushes gently upwards against the wires to conduct the electricity down into the control compartment of the locomotive. Look for the overhead device on top of the locomotive, very easy to spot.
- Q: i need three ways to save the amazon rainforest and explain how they will work? thanks
- Recycle Aim for a paperless society. Remove all the people from Earth and the animals will stop dying off due to minimised habitat and food sources as well as global warming.
