Taking large sets as an example, it is described as follows:
1. Gradually remove the load, disconnect the load switch, and turn the machine change switch to the manual position;
2. When the speed drops to 600 ~ 800 RPM under no-load, push the handle of the oil pump to stop oil supply after running empty for several minutes, and reset the handle after shutdown;
3. When the ambient temperature is less than 5 ℃, drain all the cooling water of the water pump and diesel engine;
4. Put the speed regulating handle to the lowest speed position and the voltage switch to the manual position;
5. For short-term shutdown, the fuel switch can not be turned off to prevent air from entering the fuel system. For long-term shutdown, the fuel switch should be turned off after shutdown;
6. The engine oil must be drained after long-term shutdown.
Shutdown of diesel generator set in an emergency
When one of the following conditions occurs to the diesel generator set, it must be shut down urgently. At this time, cut off the load first, and immediately turn the switch handle of the fuel injection pump to the position of cutting off the oil circuit to stop the diesel engine immediately;
The pressure gauge value of the set drops below the specified value:
1. The temperature of cooling water exceeds 99 ℃;
2. The set has a sharp knocking sound or parts are damaged;
3. Cylinder, piston, governor and other moving parts are stuck;
4. When the generator voltage exceeds the maximum reading on the meter;
5. In case of fire, electric leakage and other natural hazards.
