An electrical equipment simulation teaching system for a medium-speed diesel comprises a fuel oil rack measurement device, a sequential turbocharging control device, a crank pin temperature measurement device, a fuel oil rack signal simulation device, a sequential turbocharging signal simulation device and a crank pin temperature simulation device, wherein the fuel oil rack measurement device, the sequential turbocharging control device and the crank pin temperature measurement device are physical components of the medium-speed diesel; the fuel oil rack signal simulation device is connected with the fuel oil rack measurement device and sends a fuel oil rack displacement signal representing the magnitude of an accelerator of the diesel; the sequential turbocharging signal simulation device is connected with the sequential turbocharging control device and is for generating and outputting supercharger speed, main engine rotation speed, rack position, rack zero position and scavenging pressure signals of the diesel in a simulated manner; and the crank pin temperature simulation device is connected with the crank pin temperature measurement device and is for generating and outputting a temperature signal of spattered oil in each cylinder in a simulated manner. The system is high in operationality; and through an object simulation mode, the teaching process is allowed to integrate theory with practice, thereby improving teaching effect.

Description

technical field [0001] The invention relates to a simulation teaching device, in particular to a simulation teaching system for electrical equipment of a medium-speed diesel engine, which belongs to the technical field of diesel engines. Background technique [0002] The fuel rack measuring device, the sequential boost control device and the crank pin temperature measuring device are the main electrical equipment in the medium speed diesel engine. [0003] The fuel rack measuring device 1 is composed of a rack sensor 11 and a fuel rack measuring unit 12, and its structure is as follows figure 1 shown. The rack sensor 11 can convert the displacement signal of the fuel rack into an electrical signal in real time, which is processed and displayed by the fuel rack measuring unit 12 . The fuel rack measurement unit 12 also provides a 4-20mA output port for the monitoring and alarm system of the diesel engine, so as to realize related functions such as diesel engine load limitat...

Problems solved by technology

However, the current medium-speed diesel engine training methods are mainly based on teacher lectures and PPT demonstrations. There are no real objects in the classroom, the interaction is not strong, the students lack interest in learning, and the training effect is often not ideal.
