What is the reasonable speed range of diesel generator sets?

As a fixed equipment, the speed of diesel generator set is generally expressed in r/min, which means the number of revolutions of the crankshaft per minute, and the speed of different diesel engines is different. The speed of the diesel engine is generally fixed, and the speed is 1500r/min. If you want the diesel generator set to keep the speed stable even when the load is constantly changing, you need a governor with excellent performance to adjust the speed of the diesel engine.

 Diesel generator sets

 

      Generator manufacturers found that many generator set users consulted on the Internet about diesel generator sets with unstable idle speed, speed not reaching normal values, and high unit speed. What is the reasonable speed range of the machine, and how should the user keep the speed of the unit stable.

 

       As a fixed equipment, the speed of diesel generator set is generally expressed in r/min, which means the number of revolutions of the crankshaft per minute, and the speed of different diesel engines is different. The speed of diesel engine is generally fixed speed, the speed is 1500r/min, the speed of small diesel engine is faster, generally up to 3000r/min, while the speed of general medium-sized diesel engine is below 2500r/min, and the speed of some large diesel engines is only 100r/min , We know that the higher the speed of the diesel engine, the greater the wear and tear of its components. Therefore, in order to effectively reduce the wear of the unit and prolong the service life of the diesel generator set, it is very important to maintain a reasonable speed, so how should the user How to keep the speed of diesel generator set stable?

 

       If you want the diesel generator set to keep the speed stable even when the load is constantly changing, you need a governor with excellent performance to adjust the speed of the diesel engine. The effective adjustment of the speed can ensure that the diesel engine is working even if the external load fluctuates. Or when there is a large change, the speed can be adjusted by changing the speed to adjust the fuel supply of the fuel injection pump to ensure the stability of the speed. When the diesel engine is running at high speed, the governor can effectively avoid the "flying" phenomenon, and it can run very stably during the idling process. Even when the speed of the engine is at a certain value between idle speed and high speed, the governor can limit its speed to be very stable, and its fluctuation is small, so it tends to be stable.
