Common sense of diesel generator set

1. Oil pressure alarm of diesel generator set? Check whether the engine oil or diesel oil is enough.

2. Why does the generator stop automatically when the oil is insufficient? When the oil is insufficient, the oil warning switch inside the engine will ground the primary coil of the ignition coil, so that the ignition coil cannot be ignited and the engine stops. The method to check whether the oil level is standard: put the engine in a horizontal position, unscrew the oil dipstick, clean and dry it, insert it into the oil filler (without rotating), and then pull it out. Check that the oil level is in the middle of the dipstick.

3. What must be done when the automatic voltage regulator (AVR) is damaged and needs to be replaced? The generator set does not generate electricity. The most common fault is the damage of the automatic voltage regulator. Therefore, when someone finds that the generator set does not generate electricity, they often replace the old AVR with a new AVR to solve the problem. When users do this, they find that the new AVR loses its function after several minutes of use, and then complain about the poor quality of the AVR. In fact, AVR damage is often caused by the short circuit of the rotor caused by the overload of the generator set by the user, which leads to AVR damage. Therefore, before replacing the AVR, it is necessary to check whether the resistance of the rotor is normal (for example, the resistance of EC2500CX is 45-50 Ω). If the electrical unit of the rotor is abnormal, replace the rotor first and then replace the AVR.

4. Why does the generator output power decrease in high altitude areas? The atmosphere at high altitude is thin, and the mixed fuel provided by the carburetor main nozzle to the engine cannot be fully burned due to the relatively thin air. At this time, the engine speed may be unstable, and the muffler emits black smoke. The engine must run smoothly by changing the correct main nozzle. The output power of the engine decreases as the altitude increases, and the output power of the generator set also decreases. The power decreases by 10% for every 1000 meters above the altitude. If the correct main nozzle is not replaced, the power loss of the engine will be much greater than this standard, and the working state is unstable. The main nozzle of the standard model is only used below 1500 meters above sea level.
