An electric generator is a machine that provides us with a really important service for the correct development of today's domestic life: it converts mechanical energy into electrical energy. In other words, if we have an electric generator, the eventual failure of the main power source will never be a problem again.
Next, we will see the eleven main systems (with their corresponding parts or physical elements) that make it up and enable its operation.
If you want to know more about electric generators, our staff will always be attentive to answer your questions and provide you with relevant advice.
A detailed examination of each of the parts of an electric generator would be wasteful and excessive. For explanatory purposes, it is best to divide the electric generator into the systems (and their corresponding parts) that enable its correct operation by working integrally.
Initially, we will divide them into two large groups. The primary systems, which are two, carry out the task of converting mechanical energy into electrical energy; and the secondary systems, which are nine in total, offer support so that this main task can be carried out optimally and efficiently.
In this first large group of primary systems, we can identify two essential systems that can be differentiated by the type of energy they apply, take advantage of or convert in their operation.
This system is, so to speak, the heart of the electrical generator. Its function is essential, since it provides the energy that will be used later. Its basic element is the engine.
Here the combustion process takes place. Our models have a Perkins internal combustion engine that reaches 1800 rpm. This engine, being diesel, is characterized by its high thermal efficiency. Here the heat released from the fuel is transformed into kinetic mechanical energy, specifically located in the rotational movement of the shaft to which the rotor is attached.
This captures the mechanical energy of that rotational movement and converts it into electrical energy. This function is carried out by the alternator, which has two essential parts: The rotor and the stator. Our models feature the reliable Stamford PI 144G alternator.
The rotor is that moving part that, taking advantage of the rotation movement provided by the motor, rotates inside the stator. Since its components allow it to generate a magnetic field, when it rotates, the rotor acts as a mobile inductor in the phenomenon known as electromagnetic induction.
The stator is that immobile piece that, when the rotor rotates inside it, acts as a fixed armature. Its components are electrical conductors that capture the rotational movement of the rotor's magnetic field, thus generating electrical energy.
For this part of the process to be efficient, there must be an empty space between the rotor and the stator called the air gap.
As we know, for a complex machine to adequately perform its main task, it is necessary for other support systems to function integrally to guarantee its efficiency and maintenance. In the case of an electric generator, these support systems are the following.
Also called fuel system, it is the one that is responsible for bringing fuel to the engine. It consists of: The storage tank (which in our models has a capacity of between 150 and 300 gallons), fuel pump, supply pipes and fuel filter.
The work carried out by an engine is extremely hostile to its own components. There is too much friction there, so you need to keep it lubricated. This ensures that the engine works efficiently; that is, that there are no energy losses or excessive wear on its parts.
Since, in principle, what the engine is responsible for is a chemical reaction that generates heat, the electric generator must have a system capable of lowering the temperature and preventing the machine from overheating. It must be supplied with a suitable coolant.
In the combustion process, gases are generated that must be evacuated. So that this task is not an inconvenience, it is highly recommended that the electric generator be installed outdoors and that the pipe arranged for this purpose ends in an open place.
So that the noise of the generator is not annoying while it works, it is convenient that it has a silencer that makes it user-friendly.
Although the electric generator is normally installed on a solid and stable base, it has a system that attenuates vibrations so that the whole machine does not become out of adjustment or represent future problems.
Since an electric generator is a synchronous machine (which means that the frequency of the current is synchronized with the speed of the rotor), it is necessary for a device to measure the voltage and detect if there are any peaks (sudden increases or decreases in voltage). its voltage), so control the rotor speed to avoid them. The voltage regulator fulfills this function.
It is clear that a powerful machine must be able to be managed and controlled using the information that it provides us. The control panel of our available models shows complete and detailed information on the operation of each of the essential systems. Provides accurate data on temperature, voltage, fuel level, etc.
Of course, all these components and systems must have adequate and resistant support. So our models are assembled in a very strong stainless steel cabinet.
In summary, these are the most important systems and components that make up an electric generator and allow it to offer us reliable electrical energy. We cannot forget that its proper functioning depends on adequate and timely maintenance.
