The diesel generator set is mainly composed of a diesel engine, generator, and control system. There are two combinations of diesel engine and generator. One is a flexible connection, that is, the two parts are butt joined by a coupling, and the other is a rigid connection. The high-strength bolt is used to connect the steel connecting piece of the generator with the flywheel of the diesel engine.
At present, there are more rigid connections. The diesel engine and the generator are connected and installed on the common chassis and then equipped with various sensors. For example, the water temperature sensor displays the operating status of the diesel engine to the operator through these sensors, and with these sensors, an upper limit can be set, and the control system will pre-alarm when the limit value is reached or exceeded. At this time, if the operator does not take measures, the control system will automatically stop the unit, and the diesel generator will take self-protection in this way. The sensor functions to receive and feedback various information. The actual display of these data and the implementation of the protection function is the control system of the unit itself.
