How to adjust the speed stability of diesel generator set governor?
May 17, 2022
The diesel generator set governor is a device that automatically adjusts the fuel supply of the fuel injection pump. It can automatically adjust the fuel supply of the fuel injection pump according to the change of the external load of the diesel generator set, so that the diesel generator set can run at a relatively stable speed , so as to ensure that the diesel generator set will neither overspeed nor stop at idle speed.
The diesel generator set governor can automatically adjust the fuel supply of the fuel injection pump according to the change of the external load of the diesel generator set, so that the diesel generator set can run at a relatively stable speed, so as to ensure that the diesel generator set will not produce overspeed, nor Will cause a shutdown at idle. So how to check and adjust the stability of diesel generator governor speed?
Method 1: Set the joystick at the calibrated speed position, and slowly increase the speed of the camshaft. When the fuel supply of the fuel injection pump begins to decrease (that is, the starting point of the speeder), immediately keep the speed of the camshaft unchanged, and then carefully adjust the speed of the camshaft. Observe the adjusting gear and adjusting gear rod, and there should be no swimming phenomenon.
Method 2: When the speed of the camshaft is 400r/min, 250r/min or any other speed, use the method of changing the position of the joystick to make the adjusting gear rod in the position of various oil supply amounts. At this time, check the adjusting gear and adjust the Gear rod, so that there is no swimming phenomenon.
Method 3: When the diesel engine is unstable at low speed, the low-speed stabilizer can be slowly rotated until the speed is stable and then fixed. The factory diesel engine has been adjusted. If it is not necessary, the user should not pull it. Adjustment is only necessary after dismantling and repairing. Note that the low-speed stabilizer should not be screwed in too much, so as to avoid the minimum stable rotation speed being too high.
