How to operate a diesel generator set safely?

Diesel generator sets must be equipped with special personnel on duty during work, and often pay attention to observe a series of possible failures, especially the changes in oil pressure, water temperature, oil temperature, voltage, frequency and other important factors. In addition, it is necessary to pay attention to having enough diesel oil. If the fuel is interrupted during operation, it will objectively cause a load stop, which may cause damage to the generator excitation control system and related components. It is recommended to make a computer room rules and regulations and work flow, and check each step and precautions one by one before starting the machine every day, so as to avoid damage to the machine.

1. Preparation before starting
Before starting each time, you must check the diesel generator water tank and oil tank to see if the cooling water or antifreeze in the water tank meets the startup requirements. If it is missing, it should be filled up; Add to the specified “static full” tick mark. Then carefully check whether other relevant components have hidden troubles, find that the fault should be eliminated in time, and start the machine only after all preparations are made. The preparations before starting up are very important. Once the machine is running, these problems are discovered, which will bring inconvenience to the machine and the work after running.

2. It is strictly forbidden to start the diesel engine with load
Before starting the diesel engine, it should be noted that the output air switch of the generator must be closed. After the ordinary diesel engine is started, it needs to go through 3-5 minutes of idling operation (about 700 rpm). In winter, the temperature is low, and the idling time should be appropriately extended for a few minutes. After the diesel engine is started, it is necessary to first observe whether the oil pressure is normal and whether there are abnormal phenomena such as oil leakage and water leakage. If there is no abnormal phenomenon, increase the speed of the diesel engine to the rated speed of 150O rpm. At this time, the generator shows a frequency of 5OBZ and a voltage of 400v. You can close the output air switch and put it into use. The generator set is not allowed to run without load for a long time. If it runs without load for a long time, the diesel fuel injected from the fuel injector of the diesel engine will not be completely burned, resulting in carbon deposition, resulting in air leakage of the valve and piston ring. In addition, the automatic generator set does not need to run at idle speed, because the automatic generator set is generally equipped with a water heater, so that the cylinder block of the diesel engine is always kept at about 45 °C, and the diesel engine can be powered normally within 8-15 seconds after it is started.

3. Always pay attention to observe the running status of diesel generators
During the work of the diesel generator set, always pay attention to observe a series of possible failures, especially the changes of important factors such as oil pressure, water temperature, oil temperature, voltage and frequency. In addition, it is necessary to pay attention to having enough diesel oil. If the fuel is interrupted during operation, it will objectively cause a load stop, which may cause damage to the generator excitation control system and related components.

4. It is strictly forbidden to stop with load
Before each shutdown, the load must be gradually cut off, then the output air switch of the generator set should be turned off, and finally the diesel engine should be decelerated to idle speed for about 3-5 minutes before shutdown.

5. Operate in strict accordance with the whole operation process.
The safe operation process of diesel generator sets is the standard specification for the operation of diesel generator sets in the whole industry. For the operation process, see the article on the safe operation process of diesel generator sets on this site.
