According to the Baidu question bank, the reasons for the fluctuations caused by starting the engine are:
1. The engine is subjected to a severe fire environment.
2. The inside of the engine is too dirty.
3. The motor is grounded.
4. The voltage is too high.
5. The locomotive accelerates.
Electric machines (English: electric machines, commonly called "motor") refer to an electromagnetic device that converts or transmits electrical energy based on the law of electromagnetic induction. Divided into motors (symbol M) and generators (symbol G).
The chimney of the diesel generator throws sparks
The method is as follows:
1. The motor is slightly surrounded by fire, inspection procedures and requirements: After a ground fault of the main circuit, the ground recovery relay can continue to work if there is nohas no grounding. When stopping for inspection, open the engine side cover and inspect the interior and exterior of the engine if the above. A phenomenon occurs, first check the carbon brushes to identify whether they are in good condition and whether they are stuck. If they are in good condition, they can continue to function, but care must be taken in operation. during operation to prevent the engine from idling. If the blast is grounded due to the carbon brush, the faulty motor will be shut down without replacing the carbon brush.
2. If the engine is severely exposed to fire, inspection procedures and requirements: After the locomotive has stopped, open the side cover of the engine and inspect the interior and exterior of the engine if first and foremost. The second phenomenon above occurs, the magnetic field of the motor will be weakened at the same time. If the third phenomenon occurs, there is asmall amount of copper foil in the engine and molten copper at the bottom, but this has no effect on the operation of the locomotive. Once the inspection is complete, the faulty motor can be shut down to maintain operation.
A DC motor is a motor that can convert direct current electrical energy into mechanical energy or mechanical energy into direct current electrical energy. It is called DC motor and DC generator respectively. Its basic working principle follows the law of. electromagnetic induction456, mainly including the two main components which are the stator and the rotor.
Sparks are caused by the combustion of carbon powder. And why is there diesel but toner? Because of carbon deposits. The causes of carbon accumulation are diverse. And how can we avoid carbon accumulation? This is not only related to the stateload, the quality of the fuel, but also the quality of the unit itself and the quality of the adjustment of the fuel system. For example, long-term light loading can cause carbon buildup. If you idle for a long time, the risk of carbon buildup is high. etc.
How to clean carbon deposits? Of course, it is best to have professionals take it apart, inspect it and maintain it. Sometimes you can increase the load, which is equivalent to stepping on the accelerator, and sometimes you can eliminate some carbon deposits.
