Analysis on the Causes of the Failure of the Diesel Generator Set to Reach the Rated Speed in Operation

Aug. 12, 2021

The speed of diesel generator sets is usually expressed in revolutions per minute (r/min). The speed of 50Hz diesel generator sets sold by Dingbo Power are all 1500r/min. It is believed that you have more or less learned about the importance of stable speed for diesel of the generator set, but sometimes it may happen that the diesel generator set cannot reach the rated speed. In response to this situation, Dingbo Power has sorted out the following reasons for the failure of the diesel generator set to reach the rated speed during operation. For analysis, you can use the elimination method to eliminate and solve them one by one.

Analysis on the Causes of the Failure of the Diesel Generator Set to Reach the Rated Speed in Operation

 

1. If the electronic speed control system of the diesel generator set fails, it should be repaired or replaced in time.

 

2. When the diesel generator set is in overload operation, the load must be reduced at this time, and it is not used at the rated load of the super set.

 

3. There is an error in the setting of the speed potentiometer of the electronic speed control board of the unit. You can refer to the manual of the electronic speed controller for correct setting or replacement.

 

4. Improper adjustment or looseness of the throttle control of the mechanical speed control mechanism should be checked in time and appropriate adjustments should be made.

 

5. If the fuel pipe of the diesel generator set is blocked or too thin, the fuel is not smooth, it should be checked and repaired in time. If it is too thin, it needs to be replaced.

 

6. Check whether the diesel has water in it, and replace the diesel in time. Dingbo power recommends that an oil-water separator can be installed.

 

7. The three filter elements have not been replaced for a long time, and the three filter elements need to be replaced after the unit runs for a certain period of time. Dingbo power recommends that users must develop a good habit of regularly replacing the three filters.

 

The failure of the diesel generator set to reach the rated speed during operation will not only affect the actual power supply effect, but also reduce the life of the generator parts, resulting in a reduction in the service life of the diesel generator set. If the user encounters the situation where the speed does not reach the rated speed, you can refer to the above methods for maintenance.
