Microwave furnace rep--r skills assessment tr--ning device,Manga sand filtering method tr--ning table

1. Product overview

"Microwave oven rep--r skills tr--ning assessment device" is based on the "Standards for Education Industry Standards for the People's Republic of China -Equipment Equipment Equipment Equipment Equipment Equipment", in accordance with the "" Home Electronic Product M--ntenance Industry "professional skills released by the Ministry of Labor and Social Security of the People's Republic of China Tr--ning and Appr--sal Equipment Technical Specifications ", products developed in accordance with the teaching and tr--ning requirements of vocational education. Suitable for tr--ning teaching for professional courses such as electronic technology, electronic appliances application and m--ntenance, electromagnetic waves such as electronic technology, electronic appliances application and m--ntenance, and vocational schools.

Tr--ning installations are also suitable for technical schools, vocational tr--ning schools, vocational education centers, appr--sal stations/household appliance majors and home appliance m--ntenance workers in electromagnetic m--ntenance practice, primary and intermediate skills appr--sal and assessment.

Second, systemic characteristics

1. Supporting practical tr--ning device adopts electrical control and physical separation design, which can clearly display the relationship between the electrical part and the execution agency. The electrical control adopts a microprocessor integrated circuit. For parameters such as voltage, current, and other tr--ning components are connected to the dedicated wires, the performance and specifications of the supporting components are closely combined with the needs of the tr--ning needs to meet the tr--ning and teaching of the corresponding courses of various schools.

2. Practical. This device has the tr--ning evaluation function. According to the requirements of the skill appr--sal, teachers can easily set up concealment faults. Students can get more contact with typical microwave oven f--lures, conduct discharge tr--ning, and improve students' discharge ability. Complete the students' tr--ning of various skills such as cognition, installation, debugging, and m--ntenance; and can conduct the number of assessments and records of errors, and make a more f--r evaluation of students.

3. The content of comprehensive tr--ning is rich in content, and the working principle is clear and clear, so that students can contact and master the working methods of microwave oven as much as possible, and improve students' comprehensive ability and m--ntenance skills.

3. Technical performance

1. Experimental purpose and principle:

Sometimes the natural water sources of surface water and groundwater sometimes cont--n a cert--n amount of iron and manganese. It not only affects some industrial growth, but also is not good for the people's lives. Therefore, in the "Life Drinking Water Regulations", the total amount of iron content does not exceed 0.3 mg/L. When exceeding the above provisions or special requirements for iron and manganese in cert--n industrial enterprises, measures should be taken to try to remove them.

There are the following methods:

1. Angle:

2. Limin alkaliization method;

3, concrete method;

4. Manga sand filtration method (this device uses manganese sand filtering method).

2. M--n technical indicators and parameters:

1. Input voltage: 220V

2. Working environment: 5 ℃ -40 ℃

3. Require raw water iron content: 3 ～ 5mg/L, manganese 1 ～ 2mg/L

4. Treatment of water: q = 0.1 ～ 0.3m3/h

5. Qi and water mixture: V = 0.05 ～ 0.06m/s

6. Manga sand particle size: D = 0.6 ～ 2.0mm (manganese sand volume: 0.082m3)

7, activated carbon particle size: ø2 ～ 4mm (quantity: 0.027m3)

8. Quartz sand particle size: ø0.6 ～ 2mm (quantity: 0.027m3)

9. Air volume: calculate according to 7 ～ 10m3/m3 water

10. Reverse routing expansion rate: about 30 %
