Generator and is officially called a generator. There will be important equipment inside such as a generator. It is also a common folk name for a generator. because it is a machine that is used to convert mechanical energy into electrical energy Based on the working principle of the magnetic field with the coil cut. Or maybe it's the movement of the coil. To cut off the magnetic field and then come out into electricity that works well. The word generator comes from its full name, dynamo generator. It looks like an engine that has been made to have internal mechanisms. able to produce electricity They are divided into slow cycles or low cycles. and get high speed or high speed with different details as follows
When there is a power failure or in the part where there is no electrical installation Power must be backed up. Therefore, there must be a generator or simply called a generator to use. In this article, it tells how it works, how it works and what it does. Why is it necessary to use a generator?

Get to know the generator
Slow generator drive
Using a slow drive engine It has been used since ancient times. It is the development of diesel engines to work efficiently. but will work only about 1,500 cycles, which in the market for generators in the past This type of machine is very popular. because it can be directly connected to the diesel engine But with various parts and spare parts, the interior of the slow drive is very large, and the sound is quite loud. Therefore, it is not very popular nowadays.
Fast generator drive
Fast drying drive or high speed drive It was developed from famous brands to be more modern and functional. Able to produce electricity at approximately 3,000 cycles with development for use in gasoline and direct connection Also known as Direct Coupling, it makes for a versatile use. and reduce the volume of the machine to be smaller The internal parts and spares are not too complicated or overly complicated. therefore lighter weight
With the engine that works at speeds from 30-40 cycles, the price is cheaper than a diesel engine or a slow engine. You can also add gasoline for energy. thus helping to save on fuel costs But at the same time, the high-revving engine can also be adapted for diesel engines. which is mostly used as a bed for water cooling It also needs to be cut to become a belt tool for testing. can provide the same 3000-4000 cycles
Benefits of using a generator drive
The benefits of using the generator drive. There will be several items. Because as you know, every area needs electricity for use. Because if as long as humans still have to use tools, devices or machines that are connected to electricity The use of a generator is important. The benefits are:
- Used to back up power both in homes and businesses, thereby reducing the damage to life and work more.
- whether electrical appliances Any machine, device or apparatus that must be connected to electricity. If the power goes out suddenly There will still be a backup generator. So it does not cause a power surge that may cause the machine to be damaged easily.
- Available in small, medium and large sizes, the price is not too high. especially home appliances It is considered a price that is easily accessible.
- There are many types of machines to choose from. So you can choose to suit your needs. Especially in the use of energy that comes in many forms, including oil power, hydropower, natural gas power. or even wind power and sunlight, etc.
- Backup power for use in various emergencies and is an automatic operation. It will increase the benefits to hospitals or homes with very sick people.
Engine
The engine is the source of mechanical energy fed to the generator. The size of the engine is directly proportional to the maximum output power at the generator.
There are several factors that must be taken into account while evaluating a generator engine. Consult the engine manufacturer for complete engine operating specifications and maintenance schedules.
Fuel type used - Generator engines run on a variety of fuels such as diesel, gasoline, propane. (in liquid or gas form) or natural gas Small engines usually run on gasoline, while larger engines run on diesel, liquefied propane, propane gas or natural gas. Some engines can also run on both diesel and gas dual-fuel in dual-fuel mode.
Alternator
An alternator, also known as a 'genhead', is the part of a generator that generates electricity from the mechanical input provided by the engine. It consists of an assembly of movable and moving parts encased in the housing. The components work together to cause the relative motion between a magnetic field and an electric field, which in turn generates an electric current.
Generator fuel tank system
Usually, the fuel tank has enough capacity to keep the generator running for an average of 6 to 8 hours. In the case of a small generator, the fuel tank is either part of the generator skid or mounted. located on top of the generator frame For commercial use it may be necessary to build and install an external fuel tank.
The general characteristics of the fuel system are as follows:
- connection of pipes from the fuel tank to the engine The supply line directs the fuel from the tank to the engine and the return line directs the fuel from the engine to the tank.
- Ventilation pipe for oil tank The fuel tank is equipped with a vent hose to prevent pressure or vacuum build-up during filling and draining the tank. When you refuel, make sure there is metal-to-metal contact between the injector and the fuel tank to avoid sparks.
---> Generators Product and Work <---
- Overflow connection from fuel tank to drain This is necessary so that the overflow during tank filling does not cause liquid to spill on the generator set.
- fuel pump This is the transfer of fuel from the main storage tank to the day tank. The fuel pump is generally electrically operated.
- Fuel Water Separator / Fuel Filter This separates water and foreign matter from the liquid fuel to protect other components of the generator from corrosion and contamination.
- fuel injector Atomizes liquid fuel and injects the required amount of fuel into the engine's combustion chamber.
