In general, the parameters of the electronic governor are set at the factory. If the parameters drift, the operating conditions of the diesel generator set will change. At this time, the parameters of the electronic governor need to be adjusted again. Adjusting the parameters of the electronic governor is a meticulous task that requires patience.
Idle speed adjustment. After starting the operation of the diesel engine, it is found that the speed of the diesel engine slightly deviates from the idle speed value, readjust the low-speed setting potentiometer, and adjust it to the factory setting value. The adjustment method is: adjust the clockwise to increase the speed, and adjust the counterclockwise to decrease the speed until the required idle speed is reached. Then toggle the switch to make the diesel engine run from idle to high speed. Observe the tachometer indication, lower than the rated speed value, adjust the potentiometer to make the speed reach the rated speed. When adjusting, adjust clockwise to increase the speed and counterclockwise to decrease the speed.
After setting the idle and high speed values, carefully observe the fluctuation of the speed. During the adjustment process, it was found that the fluctuation range was more than ± 0.25%, and the stability adjustment was needed to adjust the speed to meet the requirements.
