The Function of Diesel Generator Set Governor

The function of the governor of the diesel generator set is to automatically adjust the fuel supply with the change of the external load of the diesel generator set within the speed range required by the diesel generator set, so as to maintain the basic stability of the speed of the diesel generator set. When the diesel generator set drives other working machinery, if the output torque of the diesel generator set is equal to the torque required by the working machinery to overcome the working resistance, the working condition is stable. If the resistance torque exceeds the output torque, the speed of the diesel generator set will drop, and the new stable working condition cannot be reached, and the diesel generator set will stop working.

When the output torque is greater than the resistance torque, the speed will increase. If the new balance is not reached, the speed will continue to rise and a "flight" accident will occur. Since the resistance torque of the working machinery of the diesel generator set will change frequently with the change of working conditions, it is impossible for the operator to adjust the fuel supply in a timely and sensitive manner, so that the output torque of the diesel generator set can adapt to the external resistance, so that the speed of the diesel generator set will fluctuate sharply, affecting the normal operation of the working machinery of the diesel generator set.

Due to the performance characteristics of the splash pump of the diesel generator set, it is not easy to maintain stability during idle operation, and it is easy to overspeed or even "runaway" at high speed. A governor must be installed on the diesel generator set to maintain its idle stability and prevent "runaway" at high speed. The sensing element of this governor is small in size and widely used. It can be used in several size series to meet the matching requirements of tens of thousands of horsepower diesel generator sets. It has the characteristics of good stability, good stability, high adjustment accuracy, large driving force, etc., and is easy to realize the automatic control of diesel generator sets. However, due to the complex structure and high process requirements, it is suitable for high-power diesel generator sets. The pneumatic regulator uses the diaphragm to cause the vacuum degree of the intake pipe to change, and then drives the actuator.

The electronic governor is an electronic governor that converts the speed change of the diesel generator set into the power change and controls its actuator after sampling and amplification. The regulator can adjust the fuel supply before the speed of the diesel generator set changes significantly, so as to achieve high regulation accuracy and realize the parallel operation without difference. According to the speed regulation range of the diesel generator set governor, it can be divided into three types: single program, bipolar program and full program. The single program regulator single program regulator only works at a certain speed. It is applicable to the diesel generator set requiring constant speed. The bipolar governor is bipolar. The governor only works at the idle speed and the calibrated speed of the diesel generating set. After the operator selects any speed according to the work needs, it can automatically stabilize the diesel generator set to work at any speed. In the case of frequent load changes, it greatly improves the working conditions of the operator, and also improves the working quality and production efficiency of the diesel generator set.
