[0016] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0017] The present invention will be further described below with reference to the embodiments.

[0018] Example: Reference Figure 1 The visual fuel system teaching platform includes an operating table 1 and a display mechanism, including a display rack 3 installed above the operating table 1. The display rack 3 contains multiple display components and includes multiple display slots. Each display slot is equipped with a fixing component for fixing the display components. A display board 4 is provided on one side of the display rack 3. The display board 4 contains a working principle diagram of the display components. A mounting frame 2 is fixedly installed on the operating table 1. The display rack 3 and the display board 4 are both fixedly installed on the mounting frame 2.

[0019] The operating mechanism includes an oil pump teaching aid 5 (composed of a dissecting pump and a working pump) mounted on an operating table 1. The operating table 1 has a drive mechanism for driving the oil pump teaching aid 5. The oil pump teaching aid 5 is an actual high-pressure oil pump, and its exterior is made of transparent material, allowing trainees to easily observe its internal structure and movement changes. The oil pump teaching aid 5 also has a first handle 6, which replaces the drive mechanism for manual operation instead of electric operation. The operating mechanism also includes multiple oil outlet pipes 18 located on the top of the oil pump teaching aid 5. The operating table 1 is equipped with... There is an atomization test box 7, with the oil outlet end of one of the oil outlet pipes 18 located in the atomization test box 7. A measuring cylinder 8 is placed on the operating table 1, with the oil outlet end of one of the oil outlet pipes 18 located in the measuring cylinder 8. A plunger teaching aid 9 is fixedly installed on the mounting bracket 2. A movable rod is movably installed at the bottom of the plunger teaching aid 9, and a cam is rotatably installed at the bottom of the plunger teaching aid 9. The curved side wall of the cam is slidably connected to the movable rod. A second handle 10 is provided on the cam. A storage unit 11 is provided in the operating table 1, and an oil tank is provided in the storage unit 11 for supplying oil to the oil pump teaching aid 5 and the plunger teaching aid 9.

[0020] By placing the oil pump teaching aid 5 on the operating table 1 and using a transparent material for easy teaching, the flow of oil and the movement of various mechanical parts can be observed. The actual working process of the pump is demonstrated synchronously using a holistic linkage method. For better demonstration, an enlarged version of the internal plunger pump is placed on the mounting bracket 2. It is driven by the second handle 10 below, further clarifying the oil flow and changes.

[0021] Oil is drawn from the tank using the oil pump teaching aid 5 and discharged through the oil outlet pipe. One end of the oil outlet pipe is placed in the measuring cylinder 8 to measure the amount of oil discharged each time, and the other end of the oil outlet pipe is placed in the atomization detection box 7 to determine the degree of atomization based on the spray range. Simultaneously adjusting the oil supply dipstick 19 demonstrates the oil supply situation of the high-pressure oil pump under different operating conditions.

[0022] refer to Figure 2 and Figure 3 The testing mechanism is used to monitor the oil output and atomization degree of the oil pump teaching aid. The testing mechanism also includes an atomization testing box 7 installed on the operating table. Oil-absorbing paper 13 is placed in the atomization testing box 7. The atomization degree is detected by the area of ​​oil mist on the oil-absorbing paper 13. The testing mechanism also includes an installation port opened on one side of the atomization testing box. A testing frame 12 is slidably installed at the installation port. Oil-absorbing paper is placed on the testing frame 12. A handle 14 is installed on the testing frame 12. A sealing cover 15 is rotatably installed at the installation port. A first magnet 16 is provided on the sealing cover 15. A second magnet 17 that attracts the first magnet 16 is installed on the outer wall of the installation port.

[0023] The detection frame 12 is installed on one side of the atomization detection box 7 by sliding insertion. The side wall of the detection frame 12 is provided with a sealing ring. At the same time, the sealing cover 15 is also provided with a sealing ring to ensure that the oil mist does not overflow after the detection frame 12 is pulled out.

[0024] like Figure 3 As shown, the oil outlet pipe 18 at the top of the atomization testing box 7 sprays oil mist, which falls onto the oil-absorbing paper 13. The degree of atomization is judged based on the sprayed area. The above testing process is performed manually, i.e., a single spray. After atomization is complete, the testing frame 12 is pulled out and shown to the students through the third handle 14. After the students are deemed to have passed the test, the electric spraying method is switched on to proceed to the next teaching step.

[0025] The demonstration platform is designed around the goals of being "visible, simulating, and demonstratable," and mainly consists of three parts: component display, simulator simulation, and physical demonstration. The simulator is an enlarged version of a plunger pump structure, with a transparent acrylic outer shell and a red organic plastic inner plunger, creating a color contrast for easy observation of plunger stroke changes. The physical demonstration section mainly consists of a high-pressure oil pump, a speed-regulating motor, an injector, and metering tools. Observing the oil mist and measuring the fuel level allows verification of oil quantity changes, while the speed-regulating motor realistically demonstrates the operation of the high-pressure oil pump and injector.

[0026] The entire demonstration platform is divided into three parts: First, a static display of components, where disassembled single-piston pump parts are mounted on a display board and labeled with magnetic strips, facilitating trainees' understanding of their internal structure; second, a piston pump simulator, based on the single-piston pump in the TBD234 diesel engine's high-pressure fuel pump, creating a visualized single-piston pump to visualize and quantify the fuel injection, pressure, and quantity adjustment processes of the high-pressure fuel pump; and third, a demonstration of the actual working process, dissecting two piston pumps from the integral high-pressure fuel pump. One pump body is dissected to observe the camshaft, piston assembly, and spring operation; the other pump's piston sleeve is dissected to observe piston operation and stroke changes, while fuel is isolated. The piston pumps in the integral high-pressure fuel pump are interconnected. The dissected sections are used to observe the piston pump's operation and adjustment process, while the other pistons simultaneously demonstrate fuel injection, thus realizing a demonstration of actual diesel engine fuel injection.

[0027] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of this utility model.
