Diesel engines drive generators to operate and convert diesel energy into electrical energy. According to their different uses, they can be divided into land diesel generator sets and marine diesel generator sets; according to different brands, they can be divided into domestic diesel generator sets and imported diesel Generator sets: According to different speeds, it can be divided into low-speed generator sets and high-speed generator sets.
1.Structural analysis
An ordinary diesel generator set is mainly composed of three parts: diesel engine, generator and control system. The diesel engine and generator can be connected in two ways. One is flexible connection, that is, the two parts are connected by a coupling, and the other is rigid connection. , Using high-strength bolts to connect the steel connecting piece of the generator and the flywheel disc of the diesel engine. At present, more diesel generator sets on the market use rigid connections. After the diesel engine and the generator are connected, they are installed on the public chassis, and then Equipped with various protective sensors, such as water temperature sensors, through these sensors, the operating status of the diesel engine can be displayed to the operator intuitively, and with these sensors, an upper limit can be set, when the limit value is reached or exceeded At this time, the control system will alarm in advance. At this time, if the operator does not take measures, the control system will automatically stop the unit. The diesel generator set adopts this method to protect itself. Sensors play the role of receiving and feeding back various information. What really displays these data and performs protection functions is the control system of the diesel generator set. The control panel is generally installed on the generator, called a backpack-type control panel, and some are placed on a separate panel. In the operating room, it is called a split control panel. The control panel is connected to the generator and sensor through a cable, and displays the electrical parameters and diesel fuel respectively.
Machine operating parameters. In addition, the generator set has a chassis, a coupling, a radiator, a fuel tank, and some are also equipped with a muffler and an outer cover.
