The answers given by the people above are very long. After reading the content, it is quite complicated, but it is not easy for ordinary people to understand.
In answer to the topic question, the answer is:
Which is better, an air cooled generator or a water cooled generator? Let's analyze the specific issues in detail. Air-cooled generators and water-cooled generators each have their own advantages and disadvantages (details are shown at the bottom, so I won't go into detail). It depends on the usage environment and actual situation to determine which one to choose.
The requirements of the subject: aesthetics, small size and low noise.
The answer is obvious, air-cooled generators are more suitable and silent air-cooled generators are more perfect. Not only is the shape beautiful and elegant, but the size and bruit are further reduced.
No picture, no truth, just look at the picture (silent air cooled generator)
10kW-15kW silent diesel generator, air cooled model
3kW-8 Kilowatt Quiet Diesel Generator, Air Cooled Model
Ultra-Quiet Digital Generator, Car Generator
If the above is helpful to you, I hope you adopt it! ! !
Judge by checking whether the battery voltage is sufficient. If the battery maintains sufficient power for a long time, it means the generator is operating normally. Turn the ignition on and do it. Do not start the car and use a metal tool to approach the generator pulley. There should be an obvious attraction of the magnetic field; find a multimeter behind the car to test the generator output voltage. increase and reach a maximum of about 14.5 V, indicating that the genThe generator generates energy normally.
1. Look at the nameplate and the appearance of the generator. Look at which factory it was produced in, when it left the factory and how long ago; look to see if the paint on the exterior is peeling or damaged, if the model has been disposed of, etc. Determine how new or old (quality) the generator is from the nameplate and appearance.
2. Perform a test.
3. Ask about the time of purchase, the purpose and reason for selling the generator, find out about past repairs, what major components were replaced and ask about any problems during use, so to have a more complete vision. understanding the generator. Generator status (good or bad)
4. Connect the positive test lead of the multimeter to the armature terminal of the generator and the negative test lead to the iron. The generator armature terminal voltage. the generator12V should be 13.5~14.5V, the armature terminal voltage of the 24V generator should fluctuate between 27-29V. If the voltage indicated by the multimeter is close to the voltage value of the car battery and the pointer does not move, this means that the generator is not producing electricity.
