Diesel Generator Tech

The rated speed of our Cummins diesel generator is 1500 rpm. For the generator set to maintain a stable speed, a governor is required. The governor can automatically adjust the fuel supply according to the load changes of the diesel generator set. It can be said to be an essential factor for the stability of the Yuchai diesel generator. Now, let's specifically talk about the two main uses of the governor: 1. When the speed of the Cummins diesel generator deviates from the set value, the governor can promptly make corresponding reaction actions. It also has the function of a restoring force to return the governor to its initial state. You should know that the spring in the centrifugal governor of our diesel engine parts is the part that generates the restoring force. Such a governor is also called a statically stable governor. However, a statically stable governor may also experience dynamic instability during the adjustment process. When the adjustment action is excessive and rever...
