Why need periodic generator maintenance?

What is a generator?

Picture 1 of Instructions on how to maintain, maintain your generator at home
Generators play a key role in power supply devices.

A generator is an electromagnetic device that uses the principle of electromagnetic induction to convert mechanical energy into electricity or transform electrical parameters such as voltage, current, frequency, phase angle, etc. The world's first electric generator was invented in 1831 by British scientist Michael Faraday.

Primary energy sources can come from steam turbines, water turbines, wind turbines, internal combustion engines or other mechanical sources. The popular models on the market today mainly use mechanical power generated from internal combustion engines running on diesel, gasoline or gas.

Today, generators increasingly assert their importance in production and daily life. It plays a key role in power supply devices, performing three main functions: power generation, voltage regulation and rectifier. 

Cause regular maintenance of the generator

Generators need to be stored regularly because they must be in a state of readiness for their best performance.

When a power failure or sudden incident occurs, the generator is our timely 'savior', helping to solve the job quickly and smoothly. To always need the machine can operate smoothly immediately, you must regularly monitor and perform maintenance for the generator. Why need periodic generator maintenance? The main reasons are:

  • Generators are an important backup power source during grid outages, so they must always be in a state of readiness for their best performance. Thus, even if not used, you still have to periodically check 3 - 6 months to detect internal damage and timely repair, keeping engine durability.
  • Regular maintenance of the generator can help the machine operate stably, increase the engine life, avoid small damages that can lead to more serious failures, affecting the operation.
  • You will save fuel, operating costs, repair costs pretty much if the generator maintenance periodically. Because, when the machine operates stably, the oil filter or ventilation system also operates more efficiently, will not spend too much fuel to compensate.
  • Maintenance of generators also helps you save time and costs in production and business activities, thereby developing and increasing the production of goods to serve the needs of the market, increasing revenue for the facility. manufacturing. The most important thing is that the production will not be stagnant, affecting if unexpected power outages affect the process and product quality.

Parts of the generator need maintenance and maintenance

Basic structure of the generator.

1. Motor

The engine is one of the most important parts in a generator. Therefore, users need to monitor closely to make sure there are no leaks that are dangerous during the operation of the machine. 

2. Lubrication system

The lubrication system including the engine head and oil filter should also be noticed, you should manually check the oil level as well as the quality of oil in the machine. If you are technically and know how to handle the amount of oil that is replaced appropriately, without affecting the environment, you can change the oil yourself and replace the oil filter.

3. Cooling system

The cooling system has the function of softening the heat level generated by other parts of the generator during operation, avoiding the case of explosion due to overheating. To check this section, remove the cover and consider the radiator, remove all obstructions, dust outside, if the dust is too thick, use low pressure compressed air or water to clean.

4. Fuel system

Fuel will become contaminated and corroded after about 1 year of use, so you should try to run out of fuel before they degrade and are forced to release into the environment. In the range of 3 - 6 months, even if the machine does not work you must also bring to polish, clean enough fuel to ensure the machine can always operate smoothly, in case of urgent use.

After a period of use, the fuel filter also needs to be dried to prevent moisture build up in the fuel tank.

5. Electrical system

A weak battery or running out of electricity is also one of the many common causes of a generator inactive. Therefore, if you want your generator to be able to operate effectively when needed, check regularly, replace when there is phenomenon of corrosion and fully charge the battery is a step not to be missed.

6. Exhaust system

The exhaust system treats the exhaust gas generated by the generator. You should also pay close attention to the exhaust pipes, joints, welds, gaskets to see if it leaks and affects the environment or not.

7. Other parts

You also have to check an overall outside and inside the ring to detect early if there are small animals such as bees, mice, . into the nest.

Generator maintenance procedure

Need to operate the machine regularly, even if not in use, it is also enabled for the machine to operate.

  • After 50 hours of commissioning and running for the first time, you must discharge and change the engine engine oil.
  • When it is absolutely necessary to keep the machine idling for a long time, you should pay attention to maintain the idle operation time to the minimum.
  • Operating the machine regularly, even if not in use, also enables the machine to operate for at least every three months for 30 minutes with a generator load of approximately 30% of the machine's rated capacity so that the engine reaches its operating temperature. act normally. This also helps lubricate the engine, preventing oxidation at the electrical contacts.
  • If you want to replace generator parts, you must choose genuine, clear origin, full warranty service and most importantly, compatible with other components. 
  • Ensure absolute safety for people and machines, as well as the common grid system during the implementation of inspection, maintenance and maintenance.

Hopefully, the basic information that we give above will help you to self-maintain and maintain home generator in the best way. For the more demanding stages, you should still seek additional help from qualified technicians to ensure more efficient maintenance and maintenance of the family generator. , malfunction.
