Three -phase biological logistics bed experimental device

The three -phase biological logistics bed is the biochemical reaction in the fluidized bed directly in the qi, liquid, and solidarity, and there is no additional oxygen equipment and decapyllar equipment. The biofilm on the surface of the carrier relies on the stirring of the gas, so that the particles are fiercely friction and fall off. The oxygen method has decompression to release --r oxygen and firing aeration of oxygen. Sometimes a small amount of carrier may be brought out of the bed, so there is usually a carrier (including sludge) backflow in the process.

7. Device shape size: 1200mm × 400mm × 2100mm

8. Work power: AC220V ± 10%, 50Hz, single -phase three -line system, 500W power, safety protection: ground protection, leakage protection, overcurrent protection

1. Product introduction

The device uses the real parts of the engine electrical control system to fully display the composition and working process of the engine electrical control system.

It is suitable for the teaching needs of school theory and m--ntenance of engine electrical control systems.

2. Functional characteristics

1. Real and operating engine electrical control system, simulate the operation of the engine crankshaft, can produce the work of spark plug ignition, fuel pump work, fuel injection, and other execution components, fully display the structure and working process of the engine electrical control system.

2. The teaching plate panel adopts high -grade aluminum -plastic panels with strikes, pollution resistance, fire resistance, and moisture -proof, and sprayed on the surface by special crafts; panel prints with color circuit diagrams that never fade and work. Circuit diagrams and physical objects, understand and analyze the working principle of the engine electrical control system.

3. Detective terminals are installed on the teaching panel, which can directly detect the electrical signals of the electrical control system circuit component on the panel, such as resistance, voltage, current, frequency signal, etc.

4. Diagnostic seats are installed on the teaching board panel, which can be connected to a dedicated or universal car decoder to read the engine electronic control system of the engine electrical control system and clear the fault code.

5. Demonstration panel parts use 1.5mm cold plate stamping and forming structure, beautiful appearance; the ch--n part is welded with steel structure, the surface is treated with spraying process, a self -locking wheel device, and a desktop on the base of the teaching plate. , Easy to place data, light detection instruments, etc.

6. The work of the teaching board adopts a normal 220V AC power supply. The internal circuit transformer is transformed into a 12V DC power supply. No battery is required to reduce the trouble of charging. The 12V DC power supply has a short circuit function.

7. Machinery assembly and fitter assembly virtual simulation software: This software is developed based on Unity3D. It can select 6 -level image quality. It has the design and virtual disassembly of the reducer and shaft structure, the design and simulation of common mechanical institutions, institutional resource libraries, institutional resource libraries. Typical mechanical institutions (virtual disassembly of gasoline engines), software is an overall software, which cannot be separate resources.
