Electromechanical integrated comprehensive training device

 

This system is based on the "Outline of the National Middle and Long-term Talent Development Plan (2010-2020)" for the tr--ning requirements for the tr--ning of specialized talents and innovative scientific and technological talents in key areas of economic and social development. The current manufacturing needs of China, the relevant standards and regulations for the World Skills of the World Skills Competition (World Skills). The system is comprehensive as a comprehensive manifestation of the "workstation".

 

The "workstation" can be freely combined by module to form a variety of modes. The operator not only tr--ns and tr--ns mechanical installation, electrical pipeline connection, programming, industrial robot applications, sensor applications, computer applications, m--ntenance arrangements in internships and work Therefore, mechanical and electrical skills such as touch -screen statement, servo, step -drive control control, etc., also experience the social ability and methods in professional literacy.

 

The equipment technology covers a wide range of faces and forward -looking. It is the carrier of the integration of mechanical and electrical integration, skill appr--sal and skill competition.

 

2. Product structure

 

Each independent unit is composed of tr--ning tables, executive agencies and hanging boards. In addition to independent units, each set of equipment is also equipped with tables, tool cabinets, computer desks, etc.

 

Tr--ning table: Welded with cold -rolled steel plate, spraying plastic on the surface static electricity, and the tr--ning desktop adopts fireproof, waterproof and corrosive wooden panels. There are four universal wheels and four adjustable feet under the tr--ning table. When the universal wheel moves, it can be used when the ground is not stable caused by unevenness of the ground. The tr--ning desk table is stitched with aluminum profiles, which is convenient for students to flexibly and install the workpieces in their arbitrary location and in different directions.

 

Executive agency: The aluminum plate is assembled after processing. After the surface sandblasting, the anode oxidation is either corrosive and beautiful.

 

Hanging board: Lightly below the tr--ning table, which can be easily taken and unload. The hanging panel is equipped with PLC, inverter and other electrical components, which are connected by the cable and fast plugs with the executive agency on the tr--ning table.

 

Pretending table: There is a mechanical assembly table and one electrical assembly table. Both are composed of two parts: body and table. The tablet is welded with a square tube and was welded and sprayed. It was assembled and connected. The countertop was high -density medium fiber plate, and the surface was pressed with a fireproof board to resist corrosion and anti -static. The entire assembly table can be disassembled at will for transportation and installation.

1. Experimental purpose:

The activated carbon treatment process is an organic pollutant that uses adsorption to remove odor, cert--n ions, and difficulty in biodegradation. During the adsorption process, activated carbon plays a m--n role. At the same time, the solubility of the adsorption substance in the solvent also directly affects the speed of adsorption. In addition, the level of pH, changes in temperature, and decentralization of adsorption substances have a cert--n impact on adsorption speed.

This experiment adopts the method of intermittent and continuous adsorption of activated carbon, which determines the adsorption capacity of some impurities cont--ned in water through this experiment. Hope to achieve the following goals:

1. Master the basic operation process of adsorption experiments;

2. Deepen the basic principles of adsorption;

3. Master the physical significance and functions of adsorbing the temperature line;

4. Master the data processing method of activated carbon adsorption experiments;

5. Understand the adsorption performance of different activated carbon and its choice method.
