What are the Differences of Speed Regulation Modes of Diesel Generator

The speed regulation mode of diesel generator is divided into mechanical speed regulation and electronic speed regulation, and the mechanical speed regulation and electronic speed regulation have different effects on the mechanical load. To meet the use requirements of diesel engines, speed regulators must be installed. Next, Dingbo Power will tell you the difference between electronic speed regulation and mechanical speed regulation of diesel generator sets.

For the mechanical speed regulation of the diesel generator set, after it is started, the general throttle needs to be fixed. In this way, no matter what the load output of the generator set changes, its fuel delivery is the same and will never change.

The fuel delivery of the electronically regulated diesel generator set will change with the load. When the load decreases, the fuel delivery of the generator set will also decrease. At this time, the fuel consumption of the diesel generator set will decrease, and when the load output increases, the fuel consumption of the Diesel generator will also increase.

Which diesel generator can be equipped with electronic governors?

When the load of a diesel engine changes, the speed changes greatly. Specifically, when the load decreases, the rotational speed increases. The increase in rotational speed leads to an increase in the circulating fuel supply of the plunger pump, which in turn leads to a further increase in rotational speed. This vicious cycle continues, causing the engine speed to increase and eventually gallop.

On the contrary, when the load increases, the rotational speed decreases, which leads to a decrease in the circulating fuel supply of the plunger pump. An increase in the circulating fuel supply leads to a further decrease in the rotational speed, causing the engine speed to decrease and eventually stall; To change this vicious cycle, it requires an automatic adjustment of fuel supply based on load changes. An automatic control mechanism that enables a diesel engine to operate stably within a specified speed range. Moving the fuel supply rod can change the amount of circulating fuel supply, keeping the rotational speed of the diesel engine basically unchanged.

The advantage of electronic speed regulation is not that the throttle can be automatically adjusted, which can save fuel. However, mechanical speed regulation has a fixed throttle, so the general fuel consumption is relatively higher. Generally, high-power generator sets use electronic speed regulators. Some small ordinary domestic diesel generator sets use mechanical governors, while high-power diesel generator sets generally use electronic debuggers, so the performance of generator sets becomes superior and safe.
