Car gearbox operation and test training device

The device uses an electronic control automatic transmission to become the basis. The three -phase asynchronous motor of the speed -adjustable three -phase asynchronous motor is used to perform power sources. Really display the structure and work process of the electronic control automatic transmission.

It is suitable for teaching needs for all types of theory and m--ntenance of automatic transmission theory and m--ntenance tr--ning.

 

2. Functional characteristics

1. The real -operated electronic control automatic transmission, driven by the three -phase asynchronous motor of the three -phase adjustable three -phase speed, can be displayed in the work conditions such as display, gap starting, forward gear operation, and reverse gear operation. Structure and work process.

2. The motor directly drives the transmission, and the motor and the transmission are fixed directly through the joint axis.

3. The rated current value specified on the electrical heat can be set through the inverter to achieve the use of electronic heat overload relay to prevent the motor from overloading. In order to prevent the mechanical equipment from starting/stopping the impact, acceleration/deceleration can be set through the inverter settings.

4. The tr--ning table panel adopts high -grade aluminum -plastic panels with strikes, pollution resistance, fire prevention, and moisture -proof, and spray -p--nted on the surface by special process; panel prints with UV tablet inkjet color circuit diagrams that will never fade; students can intuitively compare circuit diagrams And real, understand and analyze the working principle of the automatic transmission control system.

5. Detective terminals are installed on the tr--ning table panel. You can directly detect the electrical signals of each sensor, actuator, and control unit pipeline, such as resistance, voltage, current, frequency signals, etc.

6. The tr--ning countertop is installed with automotive instrument, pressure gauge, and real -time display of the engine speed, vehicle speed, automatic transmission gear, and m--n fuel channel pressure.

I. Overview

The system experimental device of the constant temperature and humidity unit is used to use the DC --r treatment system, and it is equipped with real parts such as compressor, --r -cooled condenser, evaporator, humidifier, electric heating device, and --r duct. parameter. Through experiments on this device, students can be familiar with the --r treatment process of DC systems and get basic tr--ning in thermal measurement and calculation. This device is suitable for experimental teaching such as "Refrigeration and *r Conditioning Principles and Applications", "Refrigeration and *r Conditioning Technology", and "Building Electrical Control Technology".

2. Device characteristics

1. Safety protection is complete: equipped with voltage leakage protection, current leakage protection, overcurrent protection, overload protection, grounding protection, can be effectively protected on personal and equipment

2. Good intuition: The device visually shows the structure of the --r adjustment system of the constant temperature and humidity unit. The --rway uses an organic glass panel. You can clearly see the composition of the --r circulation system

3. The constant temperature and humidity --r conditioner adopts a large --r volume, low -ending --r supply method to m--nt--n smaller temperature and humidity constant. And ordinary household --r -conditioning --r supply is comfortable. The general constant temperature and humidity --r -conditioning --r supply volume is 2 to 3 times the amount of --r -conditioning for ordinary household --r conditioners.

4. Due to the rapid changes in humidity, the unit needs to frequently dehumidify, and the constant temperature and humidity --r conditioner uses a cooling and dehumidification method. Therefore, the --r -conditioning refrigeration system is required to start frequently, and the requirements for the refrigeration system are very high. The machine was stopped for three minutes.

5. The inkjet of the experimental table has a refrigeration flowchart in the constant humidity unit,

6. The method of using the second use: 1. Manual stream, 2. The capacity of capillary

7. Choose an electronic expansion valve to save the way

8. Monitoring voltage, current, frequency, power, power factor, pressure, traffic, etc., can be displayed on the PC in real time, and can be printed.

9. The m--n electrical electricity of the --r conditioner can be manually connected. It has good hands -on. The connection line adopts a dedicated D4 connection line.
