1. Overview of the product of home intelligent electric water heater m--ntenance and installation experimental device products

Household electric water heater m--ntenance and installation experimental device is based on the "" "Household Electronic Product M--ntenance Works" vocational skills tr--ning and appr--sal equipment technical specifications issued by the Ministry of Labor and Social Security of the People's Republic of China. The research and development products are suitable for tr--ning teaching such as electronic technology, electronic appliances application and m--ntenance such as electronic technology, electronic appliances application and m--ntenance of vocational schools and vocational schools.

The practical tr--ning equipment also meets the vocational colleges, technical schools, migrant workers vocational tr--ning, vocational education centers, appr--sal stations / household appliance majors and home appliance m--ntenance work m--ntenance practices, as well as the skills appr--sal assessment of intermediate and ** workers.

2. Household smart electric water heater m--ntenance and installation experimental device system composition

1. This device consists of four parts: tr--ning control screen, tr--ning table, electric water heater, and tr--ning component. The tr--ning control screen (iron double -layer sub -light dense pattern spraying structure, aluminum plastic panel)

2. AC power supply (all with overcurrent protection)

Output power supply: Municipal electricity isolation output 220V 50Hz, isolation transformer output 220V 50Hz

3. DC power supply: ± 24V/+12V/+5V

4. Electric water heater: remote control closed -type water storage electric water heater

5. Refrigeration and heat -making and home appliance rep--r skills teaching software: This system is the format of the APK, which can be used on the PC side, or it can be used on the mobile terminal. This system can be manually set up by manually. Select the green box to manually set the fault point (*** can set up 39 fault points). You can also automatically perform a random f--lure point settings through the system, two fault points settings, random three fault points settings, random four random four, four random four Settings of the fault point, random fault point settings, have functions such as toolboxes, component libraries, magnifying glasses, circuit diagrams in this system. You can choose a multimeter to detect through the toolbox. Understand each component and circuit. This system starts the control circuit f--lure through the motor star triangle, and has been investigated to allow students to understand the working principle and circuit structure of the motor star triangle to start the control circuit.

1. Experimental purpose:

Anaerobic digestion can be used to deal with organic sludge and high -concentration of dissolved organic industrial sewage (such as alcohol factories, food processing plants sewage), which is one of the m--n methods for sewage and sludge treatment.

In the process of anaerobic and digestion, it is affected by factors such as pH, alkali, temperature, and load rate. The amount of gas production is related to the types of operating conditions and types of pollution. Before the design of the digestive pool, it is generally necessary to determine the design parameters through laboratory trials. Therefore, it is important to master anaerobic digestive experiments.

Through the hope of this experiment, the following goals are achieved:

1 mastering anaerobic and digestive experiments;

2 Understand anaerobic and digestion process pH, alkali, gas production, COD removal rate, MLVSS change, and deepen the understanding of anaerobic digestion.

2. M--n technical indicators and parameters:

1. Environmental temperature: 0.5 ～ 40 ℃

2. Environmental temperature: 30 ℃ ～ 60 ℃,

3. Digestive time: depending on environmental temperature, 3 to 7 days,

4. Organic glass anaerobic tank, ø 350mm × 500m,

5. Device shape size: 800mm × 500mm × 1200mm,

6. Power 220V, power 600W
