Agricultural machinery engine disassembly and assembly experimental device

Usage environment: temperature -5℃～40℃; humidity ≤80%

Engine type: Isuzu

Engine model: 4JB (original factory installed engine)

Displacement: 2.8L

Working voltage: 220V

Frequency: 50/60HZ;

Power: 200W

Teaching functions:

The tractor engine anatomical model can be used to understand the composition of the electronically controlled gasoline engine mechanical system, the appearance of each component and the connection relationship between each other, deepen students' understanding of the composition and working principle of the engine mechanical system, and help students understand abstract control theory.

M--n tr--ning projects:

Practical tr--ning on the structure and working principles of the crank-connection mechanism of electronically controlled gasoline engines; practical tr--ning on the structure and working principles of the valve tr--n; practical tr--ning on the structure and working principles of the ignition system; practical tr--ning on the structure and working principles of the fuel supply system; Practical tr--ning on understanding the structure and working principles of the cooling system; practical tr--ning on understanding the structure and working principles of the lubrication system

Technical parameters: The anatomical model is made from the original engine of the model specified by the customer. After dissection of the engine, the internal structure of the engine and the relative position of each component can be displayed; the components that can be revealed after dissection are as follows: cylinder, piston, camshaft and gear. , intake valve, exhaust valve, spark plug, fuel injector, intake manifold, exhaust manifold, generator, oil pump, throttle body, etc.;

Use the reduction motor as power input to slowly rotate the engine, and observe the transmission between internal components through the dissection port.

Technical Parameters:

1. Input power supply: single-phase AC220V±10% 50Hz, power 1.5KW.

2. Water pump parameters: Flow: 30L/min, Lift: 20m, Power: 750W

3. Piston compressor: power 750W, displacement 36 L/min, working pressure 0.7MPa.

4. *r pressure 0.1~0.3Mpa, --r flow 2.5~25m3/h, water flow 0.6~6m3/h.

5. Use a ±4000PaU type pressure gauge to measure the resistance along the experimental section of the organic glass tube.

6. The temperature is measured by a high-precision temperature sensor, and the high-precision ** signal is input to the inspection instrument for display.

7. Dimensions: 2500×500×1700mm. The shape is a st--nless steel movable bracket with double brake wheels.

8. Virtual simulation software for electrical installation in building buildings and smart buildings

Based on the unity3d design, users can choose different interactive interface sizes according to computer configuration, and six levels of image quality are av--lable. The model in the software can be rotated 360°, enlarged, reduced, and translated. There is a small assistant prompt during the use of the software, the content is as follows:

A. Wet alarm system

1. System overview: Overview of wet alarm system

2. Equipment awareness: equipped with a viewing angle, equipment det--ls (displaying the introduction or parameters of the equipment), exercises (built-in 6 multiple-choice questions, prompts for correct and incorrect choices), schematic diagram (can be entered from the schematic diagram) into the device). Equipment includes: nozzle, water flow indicator, signal butterfly valve, exhaust valve, fire alarm control, high pipe pressure gauge, high water tank, Wia control cabinet, pressure stabilizing tank, flow switch, terminal water testing device, dr--nage facilities, water pump connection alarms, hydraulic alarms, delayers, wet alarms, butterfly valves, check valves, fire pumps, safety pressure regulators, and fire pools.
