S6700H speed control board in such a governor, as the sensing element directly drive the slide valve, regardless of which direction it is moving toward S6700H, are difficult to accurately return to the original position and close the hole. This allows the engine speed is unstable S6700H, while severe fluctuations. In order to adjust the governor to stabilize in the governor also added a device, its role in the servo piston spool while moving to produce a reaction, to move to Dongguan speed control board S6700H balanced position and direction, reduce the possibility of engine speed fluctuations. This device is called a feedback mechanism. 2301 Woodward Governor imitation board governor role different speeds by changing the amount of diesel fuel injection per cycle obtained. Under certain external load conditions, a certain amount of fuel supplied to the diesel engine, the power emitted by the diesel engine with the external load balanced, stable operation of the diesel engine is at a certain speed. External load marine diesel engines are constantly changing, purports to diesel power with the new external load to adapt, it should be time to change the fuel injection quantity. In order to stabilize the diesel engine to run at a selected speed, must have special speeder ─ a governor, automatically change the amount of diesel fuel injection fuel pump through it to adapt to the external load changes. Dongguan speed control board S6700H | S6700H | faithful electromechanical provided by the Dongguan City, South City Zhongxin Electrical and Mechanical Services Department.
