Diesel Generator Over Speed Phenomenon Treatment Method

Diesel generator "speeding" phenomenon treatment method

Reason one: the fuel supply system is faulty

1 The Speed governor fly-off is off, the adjustment spring is broken, and the high-speed limit screw changes.

2 The fuel injection pump rack is stuck at the maximum oil supply position S, the rack and the rod are loosely connected, and the rack and the gear meshing position are incorrectly installed.

Reason two: a large amount of oil into the combustion chamber

1 oil bottom shell oil too much.

2The piston, piston ring and cylinder liner are seriously worn, the oil ring is wrongly installed, and the oil is poured into the combustion chamber.

Emergency measures should be taken to quickly stop the diesel engine:

1 cut off the oil circuit: the throttle is pulled to the parking position to close the throttle switch, but most of the reasons for the speed of the fly are that the throttle loses control of the oil pump plunger, and there is still oil in the low pressure oil circuit, this measure is often not fast If the diesel engine is stopped, if the high-pressure fuel pipe connection nut is unscrewed, the diesel engine of the diesel generator set will immediately“cut off the oil”and most of the cases can be stopped quickly.

2 cut off the gas path: for small diesel engines, the intake pipe is small, you can directly cover the air filter with cotton clothes, etc., or quickly remove the 5 gas filter, directly block the air inlet, in any In this case, as long as the intake passage is blocked, it can be stopped quickly.
