How do diesel generators work?
Diesel generators work by converting mechanical energy into electrical power. The main components or parts of a generator typically include:
- Engine
- Control panel
- Base frame
- Radiator
- Alternator
- Fuel system (tank, pipes etc)
- Lubrication system
- Voltage regulator
- Exhaust system
- Battery charging point
Knowing what the main components in your generator are can help when it comes to identifying and fixing issues. Understanding what your generator service engineer means when they mention a specific part can help you to both keep your generator working for longer and also identify any potential issues.
We’ve included a brief overview of some of the main parts of your power supply equipment below, so you can get to know your generator a little better.
Diesel generator engine
In a generator, the engine uses its fuel source (in this case, diesel) to create mechanical energy that the generator will convert into electricity. The size of the engine is directly proportional to the maximum power output the generator can supply.
Diesel generator voltage regulator
This part of a generator regulates the output voltage. Most generators have automatic voltage regulators (AVR) that convert AC voltage to DC current. An AVR is designed to regulate the voltage output of a generator by controlling the exciter’s input voltage. It is considered to be the brain of the generator – AVRs are an essential part of the generator.
If you have issues with your voltage regulator then your generator simply won’t work properly, it is required to maintain proper generator function capabilities as well as overall product lifespan.
Diesel generator control panel
Whilst it may seem fairly self-explanatory, it is vital to have a quality control panel and generator control system that you have a full understanding of.
Although there are some that believe that this simply acts as an ‘on-off’ switch, the truth is that it is much more than this. From your control panel, you are able to accurately monitor the levels of fuel within the system (so you know when to book generator refuelling), as well as the overall power outage. Over the years, much has been done to develop and improve the way in which this piece of technology operates, and our team at Vital Power can advise on the best options amongst our range.
Diesel generator cooling system
The temperature of the generator’s components requires regulation to prevent overheating during use. Generators often use a fan, liquid coolant or both to control the temperature of the engine. It is essential to check the coolant levels of the generator on a regular basis to ensure no burnout or overheating, so it’s essential to know about this system and where it is.
Diesel generator exhaust system
The exhaust system is also an important part to be aware of on your generator’s diagram. The exhaust fumes emitted by a generator are just like an exhaust from any other diesel engine – they contain highly toxic chemicals that need to be properly managed. Because of this, it is essential to install an adequate exhaust system to dispose of the exhaust gases.
When you contact Vital Power for a quote or advice, a member of our team will advise the best placement and options for generators, taking exhaust system location and other factors into account.
