In order to make users know more about the speed controller of diesel generator set, this paper introduces the working principle and wiring diagram of the speed controller.
The generator should be installed in a clean environment, well ventilated and easy to inspect and manage. There should be no water vapor, oil mist or other harmful gases near the generator, and there should be no hindrance in the inlet and outlet of the generator to keep the air flow unimpeded. Note that the nearby heat source will not affect the cooling of the generator. If the engine is driven by an internal combustion engine, attention should be paid to the layout of the engine room so that the exhaust and heating parts of the internal combustion engine will affect the inlet air temperature of the generator to the lowest extent.
2.If the engine does not start for several weeks, the fuel may escape from the fuel system and some bubbles may be trapped in the engine fuel system when the fuel filter is replaced. In these cases, the oil should be pumped manually to the fuel system.
The fuel leaks into the oil basin, the plunger of the diesel engine fuel injection pump wears too much, the injector needle is not closed tightly or the needle valve is stuck in the open position; the clearance between the piston, the piston ring and the cylinder is too large, so that Fuel leaks under the cylinder wall to the oil sump.
