concept-of-power-and-the-diesel-generator

The concept of power is something that has fascinated the human race for a long time now since the first time we discovered the power of fire, and it has moved on to other areas, and more advanced techniques of course have spawned under the creativity of man. Now, when talking about power, it really drives everything around us, and of course, today, we will be looking, more to the point, to the concept of the portable power solution, and this of course, is the area of the diesel generator. Now of course, there are other versions of the generator, and they might use a different type of fuel, but the focus of today really is on the diesel generator. Now this is one of the main ways that we can port power around, and the use of fuel and the internal combustion engine is one of the most efficient and easy ways that can be utilised to actually formulate a solution for men who want to build things in remote locations. It is a sense of liberty to be able to carry power around, and this is what, in essence, the diesel generator is.

Now there are many ways that you can use this portable power, and the application of the diesel generator, is really limitless. For one thing, one thing that we do know about this is that it is really cheap, and because of that, the proliferation of this can be quite extensive. Compared to the petrol prices or the electric generator, the diesel is one of the most reliable and easily accessed portable power solution that can be used in this day and age. When thinking about the kind of things that need to be done here, there are really no limits to the imagination, and from there you can sense the amount of applications that the diesel generator can be used for. Now, this might seem like a normal thing and all, but you need to really know the true impact of the diesel generator and how it is going to be able to certify the existence of many of the movements and momentum of man, in this day and age. But of course, there are always side effects to this, and this is that most of the time, a part of the energy will be lost to the heat that is escaping the generator, and while this is normal, will reduce the effectiveness of the generator in the long run.

These are some of the things that you might want to know about when talking about the diesel generator, and of course, there are other areas that you might want to look at. There is much more information out there on the net of course, and if you really want to know the technical aspects and how it works, you might want to get your hands on a manual that you can use to actually just sort of get the idea and grasp some of the concepts.

The Diesel Generator

August 23rd, 2010 aboutgenerator No comments

the-diesel-generator

It is something that we all actually should know about, and this is because it forms a part of every building, and has influenced the construction of every vehicle out there! Now in the context of things, what the diesel generator is, is really a device that uses fuel, which of course is diesel and transforms this into electricity, which is something that is really useful when you are talking about the concept of portable power in all areas. Now of course, there is much more than that, and we will try to explain this in the article below.

Now for one thing, the application of the diesel generator is limitless, in the area that you can actually use it for the home, for the outdoors and industrial applications, which means that the diesel generator has found a place in almost any place out there. Now, for the most part, you can use this for almost any need, because of the universal nature of the generator, it can generate power and power almost any appliance that you need. It represents a core power source as well as a good back up that can be used in the case of any emergency.

Now, we need to know how it works don’t we. For one thing, the whole theory behind this is that it uses the power of the internal combustion engine to do its work. All in all, what is going to happen is that when you are doing this, you will see that the ignition point really comes from the mixture of air and fuel, which sparks the energy needed to drive the generator. The energy of that explosion moves a piston that is converted into the rotational momentum of the device that is called the crank shaft, which really is the core way that the generator powers itself.

If you are confused, do not be, because it is really a simple theory for you to follow. The movement of the piston and the crankshaft is then translated to kinetic energy that can be used to turn things like wheels or even other parts of a vehicle. But of course, we should not limit ourselves to just thinking about the concept of that power to the generator, and so we should be allowed to do things that we need. Really it is a simple transformation and conversion of power into kinetic energy, which can be used to transform into more power, at the end of the day.

These are some of the things that you might want to know about when you are concerned about the diesel generator. All in all, what needs to happen is that when you are going to get your idea around this, you need to do that the diesel generator, by itself, is a core component of many industries, and it has taken the concept of portable power really to another level. We can only imagine how the world would be without the diesel generator.

Diesel Generators, How They Are Made

August 22nd, 2010 aboutgenerator No comments

diesel-generators-how-they-are-made

This is a technical article that talks about how diesel generators are made in the first place, and of course, the technology behind this is actually simple if you think about this. Most of the time, the basis for such technology comes from inspiration, and in the case of the diesel generator, this inspiration actually comes from the car and the internal combustion engine, which will then help you to actually find out more about how they work in the first place, and of course, understanding this, after reading this article is going to be a little easier.

Now what happens is that the generator is a combination of two items, and in this case, it is the diesel engine and the electrical generator. The diesel engine takes its place from the car, and within the processes that go inside is internal combustion, which at the end of the day, uses the power of ignition and the burning of the fuel, combines with the movement of the diesel generator to actually produce the kind of power that you need at the end of the day. It is a simple marriage of ideas that has produced one efficient and reliable piece of equipment.

The other aspect of the generator is the alternator, which of course is an electrical generator, which means that it is able to transform mechanical energy into electrical energy, a critical part of the operation of the diesel generator that we need to be aware of. How it works is that it actually uses a system of motors to actually achieve this, and of course, the windings that are within the actual housing of the generator will move about and this will produce the kinetic energy needed to drive the turbines and winches within to produce the electrical energy.

So in essence, how it works is quite similar to the concept of the dynamo, something that we all know about in this day and age. While the dynamo directly taps into the movement and kinetic energy to actually morph in into usable electrical energy, the electrical alternator does this in a slightly more efficient way that normal, and this causes and produces a much higher output than you would have if you have used the largest dynamo. Now, the concept of the dynamo is more present within water situations, where dams and waterfalls are used to power the dynamo.

Now you know a little more on how they are made, and what you need to know about the interior of the machine itself. All in all, what is going to happen is that you are going to need to find out more information about the whole concept, and how this is going to help you out in the first place, and while the internet might not be so helpful to begin with, it is going to be able to give you points of information that you can use to make the whole concept of the thing more feasible.

The history and feature of diesel generator

July 12th, 2010 aboutgenerator No comments

Diesel generator is a small item of power generating device, it consumes diesel, and takes diesel motor as the prime motor to supply power to generator. The entire machine is generally composed of diesel motor, generator, control tank, combustion chamber, battery, protection device and other components. It can fixed on basic facility, or located, even for mobile use. Diesel generator belongs to these generating devices which can not work successively, if it has been working for twelve ours, its output power should be lower than rated power. Although diesel generator ahs low power, it is agile, convenient, and easy for operate and repair, so it is widely used by miner, railway, wild construction site, enterprise, hospital and so on.

In 1897s, the first diesel generator in the world is invented in Augsburg which is a province of Germany, and it is invented by Rudolf Diesel who is the founder of MAN enterprise, so the diesel motor is named as his name. MAN enterprise is still the biggest diesel generator manufacturer in the world, its generator can have a capacity of 15000KW, and it is the main power supplier in ocean shipping industry. Our country’s large-scale diesel generator depends MAN enterprise, such as Dongjiang electricity company in Guangzhou province, Fushan electricity company so on. Now the earliest diesel generator is still preserved in Germany’s national museum for exhibition. Now we’d like to introduce the working theory of diesel generator. In the combustion chamber of diesel motor, purified air which is filtered by air cleaning machine is well mixed with high compressed foggy diesel which is jetted through nozzle. Under the up-down compression of piston, the volume becomes smaller, and the temperature in the combustion chamber is rising so fast, when it reaches the burning point of diesel, the mixed air burns fiercely, and the volume expands, so it pushes piston down, in that way it makes the crank turning, because the alternative current generator is installed coaxially with crank, so when the diesel is turning, it drives the rotor of generator. Because of the electromagnetic induction, generator can output inductive voltage, and it runs through resistance, it will produce current.

The advantage of using diesel motor is that when the cost of fuel and working condition change, the change of fuel-consumption efficiency is flat. It is also famous for its reliability, durability, low poisonous air emission and wide range of use.

The generator group shoulders the burden of national economy and daily life’s electricity demand, in the future it will still play an important part for a long time. With the development of civilization and economy, the former generator group can not meet people’s need, so the trend of future generator group should be along low energy-consumption, environment protection, good looking appreance.

Tips for choosing and buying the perfect diesel generator

July 11th, 2010 aboutgenerator No comments

Nowadays diesel generator is widely used in daily life, so everyday we are involved in buying all kinds of diesel generators, but it is difficult for customers to buy a perfect diesel machine. This particle is focused on finding some tips for buying a perfect diesel generator.

Now the expert reminds customers to do the following things when buying a new generator, firstly, we should what band it is, secondly, we should know the manufacturing process, when we are testing the generator, we should watch whether the voltage and frequency is stable or not, whether the foundation of voltage is fast or not, whether the vibration is big or not, the size and color of engine’s smoke, and so on.

Here are the eight traps which we should consider when we are buying a new diesel generator.

1, we shouldn’t confuse the relation of KVA and KW. Sellers usually regard KVA as the overstatement of KW, and sell it to customers, actually, KVA is apparent power, and KW is efficient power, the equation is KVA=0.8*KW, generally, import generator group is using KVA as unit of power, but for domestic device, we use KW as a unit, so when we are calculating power, we should make 80% discount of KVA.

2, make a confusion between rated power and back-up power, when selling generators, seller only say “power”, and mistake back-up power for rated power on purpose, and sell it to customers. Actually, in generator machinery, we define that the power of diesel generator is larger than power of generator, because of the energy-consumption during the process. If seller sells it to customers for mistake, it will severely lower the life if machine group and bring high maintenance.

3, renew second-hand generator and sell it to customers, so when we buy it, we should caution and buy new one.

4, only tell the band of diesel generator, and do not tell customers the production place and the band of machine group, such as Sweden’s Volvo, Britain’s Stanford and so on, actually, any diesel generator group can not be fulfilled by one company, so customers should know the band and manufacturer of diesel generator.

5, do not talk about the band of diesel generator and generator, only talk about the price, that is absurd, which we should forbid.

6, do not talk about the condition of assembly, actually they are very important, which should be pointed in contract.tips-for-choosing-and-buying-the-perfect-diesel-generator

How To Safely Operate A Generator

January 12th, 2010 admin No comments

generatorAll generators operate differently, so please consult the instructions that came with your model.
Powering Up Your Generator

* Check fuel level.
* If you must add fuel, be sure generator is cooled down.
* Do not over fill.
* Check oil level.
* Check filter.
* Check voltage selector to make sure it matches the type of application you are connecting to (CHOOSE BETWEEN ‘120-VOLTS AND ‘120-VOLT/240′).
* Move generator outside to well-ventilated area.
* Place on a firm, level surface.
* Connect a heavy duty, outdoor-rated power cord to generated, or connect appliances directly to generator to generator.
* Turn generator’s circuit breaker off.
* Turn power switch on.
* Pull cord.
* Let generator warm up before turning circuit breaker back on.

Gasoline
Some generators operate on unleaded gasoline. Others use diesel fuel. Five gallons of gas will power a 5,600 watt generator for about eight hours. One gallon of gas will power a 3,000 watt generator for about 3 1/2 hours.

Additional supplies
You will also need multi-gallon, vented containers for storing gasoline (fill before storm comes), engine oil, an outdoors-rated extension cord and a carbon-monoxide detector.

Caring for your generator

* Never over fill gas.
* Don’t use stale or contaminated gas.
* Avoid getting dirt or water in the fuel tank.
* Turn fuel valve off when transporting or storing generator. This keeps fuel from diluting engine oil and damaging engine.
* Run generator at least once a month. This lubricates the engine, recharges the battery and lets fresh gas through the carburetor.
* When storing a generator for more than two months, drain fuel and add fuel conditioner to top it off, following directions on the label.
* Change oil regularly, according to your model’s manual.
* Change filter regularly. according to your model’s manual.

Safety Tips

The risks (if you don’t do it right): carbon-monoxide poisoning, electrocution, fire and explosion.

* Never use wet hands to operate the generator. Never let water come in contact with the generator.
* Never run your generator in a garage because the carbon-moxide exhaust is toxic. Find a well-ventilated space with some cover, but be sure the generator isn’t positioned outside an open window. Use a battery-powered carbon monoxide detector. Always turn the engine off before refueling and let the generator cool.
* Don’t spill fuel. It can ignite.
* Store fuel and generator in a ventilated area and away from natural gas water heaters. Vapors can escape from closed cans and tanks, then travel to the pilot light and ignite.
* Never feed power from a portable generator into a wall outlet. This can kill linemen working to restore power. It also can damage your generator.
* Don’t use power cords that are frayed. This can cause a fire. Be sure all prongs are intact and that the cord is outdoor-rated. The cord’s wattage or amps must not be smaller than the sum of the connected appliance loads.

Shopping Tips

* Ask the dealer how many watts it will put out and for how long and how big a load it can handle.
* You could spend around $350 for a 2,400 watts model, $600 for an industrial-strength model. A television uses 300 watts; a freezer, 330; a water heater 3,000.
* Compare brands and models. Get manufacturer’s toll-free numbers for technical questions.
* Make sure you have the right cords and connectors or the generator will be useless. Consider an auxiliary fuel tank.
* Don’t fill fuel tanks until right before the storm. Stored fuel will grow stale and is unsafe in a hot garage.
* Most starters use rope pulls. If your use a battery, make sure it’s kept charged.
* Buy now, not after the storm. You’ll pay a lot less.

Introduction to the Diesel Generator

June 10th, 2009 Grace 11 comments

Most people know that diesel engines in automobiles provide higher mileage, making it an obvious choice for heavy-duty transportation and equipment. Diesel is priced heavily when compared to gas, because it has a higher energy density and more energy can be extracted from diesel when compared to the same volume of gas. Diesel fuel has heavier, oilier and has a higher boiling point when compared to gas. When you compare petrol, gas and other fuels, diesel is least flammable. When compared to gas generators, this generator requires less maintenance. Being rugged and reliable, it can work for long hours at a stretch. Modern diesel generators can overcome noise issues. Onsite fuel delivery is available. These generators are used in many industries like mining, telecommunications, marine and agriculture applications, hospitals, industrial plants and commercial buildings. Although they are built for large loads, modern diesel generator is designed to comfortably handle small loads without wet stacking. These are available in single phase and there phase power generators.images

 

You can find different types of diesel generators in the market. Small portable diesel generators range from 1kva to 10kva, while larger industrial generators range from 8kva -30kva for homes, small shops & offices up to 2000kva used for large office complexes, factories and power stations.

 

The typical diesel generator is run at 1800RPM and is water cooled. This makes them great work horses as they are able to run for longer periods of time when compared to the gasoline generator and without much maintenance work required. They are also cheaper to operate due to the low fuels costs as compared to the other types of fuels such as gasoline and propane as well as the lowered maintenance costs due to there being no spark plugs and carburetors.

 

The diesel generator operation is similar to that of the diesel engine. There are two types of diesel engines. The 2-stroke and the 4-stroke operation are the two types. The 4-stroke operation is the one that is typically used in diesel generators. This process as the name implies uses four strokes.

 

The first stroke is the power stroke where a fine mist of diesel is sprayed on top of the piston in the hot compressed air space. The fuel is then ignited and the air on top of the piston expands. This pressure then causes the piston to move down and this motion is converted to a rotary motion by a rod that drives the crankshaft.

 

The next stroke is the exhaust stroke which is initiated by the momentum of the crankshaft turning and the piston then moves up. The next stroke is the suction stroke and this is when the piston reaches the top and the momentum continues so that the piston reverses in direction. The piston then moves down and the compression stroke is next where the direction of the piston is again changed after the lowest point. This cycle continues for the operation of the diesel generator.

 

Although the diesel generator is by far the cheaper generator overall it can cost a lot more to set up initially and this can be a deterrent to many generator users. The generators are also not as clean burning as the other fuel generators although this has improved much in recent times. The diesel generators may also require a larger store of fuel but this is much safer to store than gasoline. Another disadvantage of the diesel generator is that it can be a lot more noisy compared to their counterparts.

 

Many persons however believe that the savings that can be derived from an investment in the diesel generator are indeed well worth the disadvantages. The savings in fuel and maintenance are immense and the hassle free maintenance is a great plus. This is the reason many commercial generator users opt for the diesel generator. Diesel generators are available in mainly larger designs but can also be found on occasion in smaller units.
