Electrical / | How to choose a generator |
It is hard to imagine what our lives would be if there was no electricity, or rather, the opportunities that it provides. In today's world, power — fundamental factor not only for the majority of human activities, but also one of the main conditions of progress.
However, in everyday life, we often have to deal with such phenomena as shortages or lack of stable voltage power supply, especially in windy weather, or complete power outage, due to various objective reasons.
The most difficult thing, — is to preserve the possibility to use the achievements of civilization, while relaxing in a country house or cottage, as well as during the period of repair or construction work.
The only reasonable solution in such situations — become an owner, albeit small, but, personal power. As difficult to believe, but it allows you to purchase a stand-alone or remain independent of the vagaries of the weather or seasonal communal undertakings.
Selection of generator — serious reason to think & hellip;
How to determine which of the hundreds of offers available on the market, will be the best, — the question is not easy. Therefore, before penetrate into the wilds of the technical characteristics of each type of generators should consider practical-operational side of the issue.
Modern generators can run on different fuels, but regardless of this, they have to be reliable, — that is, to ensure stable and uninterrupted operation. In addition, not every consumer wants to bother with the complexity of managing hardware, — than it is easier and more accessible, the better.
And if you add to this, a low noise level during operation, a high level of environmental safety and the possibility of service support and maintenance from the manufacturer, you get a general portrait of the ideal of the generator.
Why the choice of generator capacity so important question
The power level of each oscillator — it is, in fact, the definition of its features. If we consider that the main task of the autonomous power supply — ensure that the volume of electricity that is required for the normal person to work and life, it becomes clear why it is important to take into account what kind of appliances will get power from it.
Because, if the generator is a small amount of power to connect multiple high-power electrical appliances (such as refrigerators, microwave oven), it is possible not only by its overload, but also failure.
In the best case, improper use can result in electric excessive fuel consumption. But in the future, this practice leads to a decrease in life of the product.
In order to avoid undesirable consequences, it is necessary to calculate the total amount of power that will be needed to complete the work of all electrical equipment. In other words, the amount of purchased power generator should be 30% higher than the total electrical power that will be connected to it.
Crossroads Fuel: petrol, diesel or gas?
By type of engine generators are divided into gasoline, diesel and gas. And each of them has its own features and benefits that must be considered when choosing an autonomous power source.
The main criteria, — this is the technical aspects that define the operation of the entire device:
· Power
· Total engine hours
· The number of hours of continuous operation for a gas station
· The amount of fuel consumption per hour, depending on the load conditions.
However, the principle of operation of each oscillator is the same, irrespective of the fuel: the fuel enters a combustion chamber, under the influence of the sparks and the mixture is ignited. As a result, there is a release of thermal energy which the rotating drive of the generator is converted into electricity.
What is special two-stroke gasoline generator
Power generators with petrol engine type are the most common. They are easily and quickly run in any weather, comfortable and easy to maintain, and even gasoline, which is needed to operate the device, there is no problem.
Modern manufacturers offer two types of gasoline engines for portable power plants: two-stroke and four-stroke.
From the point of view of consumers, generators with a two-stroke gasoline engine has many advantages for seasonal use:
· Ease of Management
· Compact and light weight — pledge mobility
· Slight noise and vibration, therefore, does not require additional sound insulation
· Low price.
Gasoline generators are ideal in case of a sudden power outage, as a backup power source. Also, the device is very convenient to use when traveling to the nature, — fishing, picnic or hunting, to boil water, recharge laptop and mobile, to provide additional lighting or to turn on the TV and stereo system.
In addition, generators with a two-stroke petrol engine excellent job charging car or boat battery.
During construction or maintenance work, gasoline generators are indispensable as a source of food for the gun, electric drill and other equipment.
What's special four-stroke gasoline generators
For comparison, the four-stroke gasoline generators are more:
· high power
· economical fuel consumption
· high service life of the duration and continuous operation
· complex design
· clean exhaust
· strong management.
But at the same time, gasoline engine generators with four-stroke type are stationary, so their operation is usually limited to the installation site.
What is so special diesel generators
Independent stations operating on diesel fuel, are second in popularity among consumers. And above all, because diesel engines are reliable, economical, they have a high margin of safety and are designed for continuous operation. That is ideal for independent power supply stable.
This diesel power sources are distinguished:
· high output power level
· minimum fuel consumption
· availability and low price of fuel
· a high level of service life and duration of continuous operation
· range of management capabilities.
· A wide range of modifications.
In other words, diesel generators, from a consumer perspective, — a relatively great opportunity to get more power at the lowest cost.
However, despite all the advantages, and diesel power sources are not perfect. Some disadvantages inherent in these devices:
· The high cost (which, however, quickly pays off)
· A lot of weight and, consequently, low mobility
· High noise and vibration, the need for additional sound insulation
· Sensitivity to fuel quality and proper use
· The sensitivity of the fuel at low temperatures, (if you do not use the protective cover, which is not cheap)
· For the most powerful models, — the need for a separate room equipped with ventilation.
What is special about the gas generator
In recent years, a niche in the world of independent power supply could take and gas generators. Due to the availability of gas, these devices are quite capable to solve the problem of power: to fuel generators can be connected to the gas cylinder, the gas pipeline or a home refuel at gas stations.
However, despite the good performance, this type of generator still remains inaccessible because of the high cost of the device itself.
Summing up & hellip;
For selected clock optimally meet the needs must take into account:
· Device power
· Tasks use
· Location and intensity of use
· Budget capacity
· Features of service.
For example, for periodic visits to the country, or the temporary nature of construction works, economically preferable generators with petrol engine type.
Whereas the need for a stable and uninterrupted power supply or manufacture of a country house is able to provide only a generator with diesel engine type.
If the correct approach to the selection of an independent source of energy, and take into account all the nuances of this type of equipment will give you the maximum comfort of life everywhere and in any condition.
