Diesel Generators

I have a 20 kw westerbeke diesel generator that surges speed wise.?

I can visually see the electronic speed actuator moving in and out when this is happening. Should I replace the actuator or could it be something else. This is in a boat.

I would first replace the primary and secondary fuel filters. It could have a governor problem in the injector pump. The fuel transfer pump may be bad (not keeping the injector pump body fully charged). The "actuator", actually may be the run/kill solenoid. If so, some have two windings, a "pull in" and a "hold". Check to see if voltage is constant on the hold winding when it is running. Most generators that I have seen and worked on, have a fixed throttle setting on the injector pump.

what size diesel generator is needed to power a 30hp 230/460volts motor?

we have a compressor that is connected to a 3-phase 30hp 230/460volt motor, we want to power it with a diesel generator. Which will be placed approx. 300ft away

The generator will need to produce approximately 23Kw and with a 25% surge factor, you will need approximately a 30Kw generator.
A typical commercial generator with this output has around 100 HP.

generator related question?

we are using 1000kva generator, for our plant, it is driven by diesel engine which consumes 250 gallons minimum daily….pls answer me is there any option for reducing diesel consumption, ans also we have 200 kva generator for small accomodation purpose.

can u use this 200kva generator instead of 1000 kva bu placing stepup transformer and then stepdown to normal voltage,,,is there any possibility like that..pls answer me…

OR is there any thing which drives 1000kva generator without diesel consumption…….

u cant use 200kva instead of 1000kva.. eventhough u use stepup transfrmr, u couldnt meet the required load demand with that 200kva generator

I have a Diesel fuel Generator 600KVA, I uesd it 10hrs a day. one litter of Diesel fuel is US $0.8?

So for one litter of diesel fuel, how many KWh of electricity can poduced? I used for 2512pcs 41W of fluorescent Tube.

It varies a lot depending on the generator’s efficiency. Usually 3 to 6 kilowatt hours per liter.

How many hours can I expect this generator to last?

I have a Kubota GL7000 portable diesel generator….. now I’ve followed the recommended maint. schedule on it, new fuel filters, oil filters, oil changes, etc….. I have just under 1,000 hours on it right now, it smokes a little when it’s cold but when it warms up it runs nice and smooth and with no smoke, it seems to me that it’s running really solid and I have no complaints or problems, but I’m curious how long a generator like this (2 years old) should last me?
I use this generator for my business about once or twice a week…. sometimes just for an hour or so and sometimes it’ll run 8 or 10 hours straight

ok so you a caring owner of the kubota gen. well a bit of smoke is ok w/ 1k hrs and you dont say how many times you use it ie you start it up just to ck it or your actualiy putting a load on it with power being draw on the gen. ?? also its important that the oil your using is combatible with the weather and area your using it in trust this 40 w in the rockies aint gonna work and in winter you need a heater in the sump too keep oil warm

Can one covert a 7.2 liter diesel motor into a backup generator? And does it make sense to do?

I bought an old moving truck that I only want for storage. It will be parked on my off grid property. I would like to rig it to run a generator that could charge up a large bank of batteries for when my solar isn’t collecting enough power. I know it can be done but I’m curious first, how to do it, and second, if it’s worth doing? Thank you very much for your input.

The engine in the truck is designed and built to move the truck. There are far cheaper to run and more effective options for direct charging any battery bank. You need a small diesel or possibly a quality OHC petrol engine on gas direct coupled to a suitable alternator, regulator and control system. The engine you are suggesting has the ability to spin up a huge alternator - possibly ten times bigger than needed for your purpose so expect fuel consumption to match.

A fixed speed stationary engine has much different cam and fuelling profiles, and a very accurate engine speed governor fitted to ensure the correct frequency and phasing at all times when the unit is under load. This means that the truck engine will be very unsatisfactory for your proposed alternative use.
