The difficulty of engine starting is that the starter can drive the engine to turn at normal speed and has obvious signs of running, but it can't start, or it needs to start repeatedly or for a long time before the engine can start. For the trouble of starting, it is necessary to distinguish between the cold car and the hot car, or whether the cold car or the hot car appears. The cause of this failure is usually in the fuel injection system.
Once the external power supply is interrupted, the diesel generator should start the generator set and supply power to the low voltage busbar of the substation to ensure the continuity of the power supply. The starting diesel generator generally has manual starting mode and automatic starting mode. Generally, manual start is used for the substation with someone on duty, and automatic start is used for the unattended substation. However, the automatic starting device is often accompanied by manual starting function to facilitate its use.
Many diesel generator shaft parts, such as crankshaft, camshaft, drive shaft and so on. The common damage forms of shaft parts are bending, wear and fracture. Test of shaft parts of diesel generator set, examination of wear and fracture test.
The injection pump is called the "heart" of the diesel generator set, which shows the importance of the fuel injection pump of the diesel generator unit. It is the most important component of the diesel fuel supply system. Its function is to increase the pressure of the diesel generator set and to supply fuel to the fuel chamber on a regular and quantitative basis according to the requirements of the working process of the diesel generator set.
