Tractor wiper system teaching and training platform

This equipment is based on the actual 750P tractor wiper system and fully demonstrates the structure and working process of the tractor wiper system.

It is suitable for the teaching needs of schools on the theory and m--ntenance tr--ning of tractor wiper systems.

2. Functional features

1. A real operational wiper system, fully demonstrating the structure of the wiper and cleaning systems.

By operating the wiper and wash gears of the combination switch, you can perform intermittent wiper, low-speed wiper, high-speed wiper, wash wiper and other wiper and wash system functions, truly demonstrating the working process of the wiper system.

2. The panel is made of high-quality aluminum-plastic panels that are impact-resistant, pollution-resistant, fire-proof, and moisture-proof, and the surface is sprayed with primer using a special process; school students can visually compare the circuit diagram and the actual object to understand and analyze the working principles of the wiper and cleaning system. .

3. There are detection terminals installed on the panel, which can directly detect the electrical signals of various circuit components of the wiper and cleaning system, such as resistance, voltage, current, frequency signals, etc.

4. The panel part adopts 1.5mm cold plate stamping structure, with beautiful appearance; the bottom part adopts steel structure welding, and the surface is spray-coated. It has a self-locking caster device. The base of the teaching board is equipped with a tabletop of about 40cm for easy placement. Materials, light testing instruments, etc.

5. It works with ordinary 220V AC power supply, which is transformed into 12V DC power supply through internal circuit transformation and rectification. No battery is needed, which reduces the trouble of charging. The 12V DC power supply has anti-short circuit function.

6. Mechanical assembly and fitter assembly virtual simulation software: This software is developed based on unity3d, with optional 6-level image quality. It is equipped with the design and virtual disassembly and assembly of reducers and shafting structures, the design and simulation of common mechanical mechanisms, and a mechanism resource library. For a typical mechanical mechanism (virtual disassembly and assembly of a gasoline engine), the software is a whole software and cannot be individual resources.

A. Reducer design and virtual disassembly interface can choose worm gear bevel gear reducer, two-stage expanded cylindrical gear reducer, bevel cylindrical gear reducer, coaxial cylindrical gear reducer, bevel gear reducer, and one-stage cylindrical gear reducer. Gear reducer.

Technical Parameters:

1. Input power supply: three-phase AC380V±10% 50Hz, power 1.5KW.

2. Centrifugal fan parameters: --r volume 2200 m3/h, wind pressure 1000 Pa, power 1.5KW.

3. Partial suction exhaust hood, made of transparent organic glass; experimental pipe diameter Φ160mm.

4. The Pitot tube flowmeter is equipped with an inclined tube micro-pressure meter to measure the flow rate: measuring range -10-700pa.

5. The 24-tube inclined tube differential pressure gauge measures the pressure distribution at each point of the cylindrical specimen and the wing specimen, with a length of 800mm and a height shift scale.

6. The experimental --r duct, the --r inlet section and the --r outlet section are made of 304 st--nless steel, and the experimental section is made of transparent organic glass. Various test pieces can be switched and installed in the experimental section, and they are connected with flange nuts for easy disassembly.

7. Dimensions: 1700×500×1700mm. 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.
