The practice equipment is suitable for "Refrigeration Foundation", "Refrigeration Equipment M--ntenance Industry", "Refrigeration Equipment M--ntenance Works", "*r Conditioner M--ntenance", "*r Conditioning Technology" and other professional curriculum tr--ning opened by the technical secondary school, high vocational colleges, technical colleges teaching

2. The practical tr--ning equipment is m--nly based on the --r -conditioning compressor, condenser, evaporator, drying filter and other devices as the tr--ning platform. Students can use various tr--ning tools to complete the tube, bending tube, tube expansion, welding, fluoride, fluoride, fluoride, fluoride, fluoride, fluoride, fluoride, fluoride, and fluoride. , Leakage and other refrigeration pipeline tr--ning. Suitable for technical colleges and vocational schools as tr--ning for basic skills of refrigeration.

3. The equipment has a set of capillary pipelines.

4. A set of equipment electronic expansion valves and controllers to understand the traditional cooling electronics flow method, so as

2. Functional characteristics

1. This device integrates refrigeration and --r conditioning, refrigeration system electricity connection, pressure detection, vacuum, filling refrigerant and operation debugging, including all steps for the refrigeration system m--ntenance, which can meet the needs of tr--ning teaching and practical engineering tr--ning.

2. The device uses a modular design, the electrical control is separated from the cooling system, and the electrical part is set to set the detection point. The terminal and the output connection terminals of each road can be measured for students to perform independent wiring, testing, and long -distance operations.

3. The tr--ning platform visually shows the system structure and working principle of --r -conditioning. You can clearly see the real objects of the refrigeration system structure and m--n components. The system also is equipped with voltage meters, AC current meters, pressure gauges, signal indicator lights, etc., so that the real -time working state of the entire --r -conditioning system and refrigerator system is clear at a glance.

4. The tr--ning device uses a compressor as the tr--ning object. The entire compressor is fixed on a work table, which is both beautiful and generous, but also conducive to students' actual operation. This device is also used for --r -conditioning system pressure. The entire device adopts a modular design. Students can use the refrigerant in the --r conditioner tr--ning in --r -conditioning tr--ning to recover and reuse them, which can save a lot of social tr--ning costs.

5. Use this device to learn the control circuit and knowledge of the split type --r conditioner. The --r -heating pump split --r conditioning part has the following refrigeration mode, heating mode, dehumidification mode, --r supply mode, and four working modes. There are three working modes: standard mode, energy -saving mode, and quick -frozen mode.

I. Overview

 

The hierarchical lattice circuit experimental platform is the teaching and assessment of electrical control content such as the major, technical and related majors of the major, technical colleges, vocational schools, and related majors of vocational schools, social electrical tr--ning, and county and electricity appr--sers (stations) and other units. Develop experimental equipment. Can be used for classroom demonstration, machine tool electrical control scheme and experimental internship. Because the equipment uses actual electrical appliances, it can be used as an internship equipment in the electrical m--ntenance equipment in social electrical vocational tr--ning, and it is also a device selected in the professional qualification tr--ning assessment. Improve students' hands -on ability and overcome the teaching of only in the past, it can only be taught on actual equipment, and it costs high and difficult to achieve the weakness of teaching purpose. At the same time, it provides effective equipment with high -level m--ntenance skills tr--ning, which has achieved the purpose of spending less and significant teaching effects.

 

2. Scope of application

 

This device is suitable for the simulation of T68 -type horizontal bedding electrical control and the skill assessment of the T68 -type horizontal bedding electrical f--lure exclusion.

 

3. Technical performance

 

1. Enter power supply: three -phase and four lines (~ 380V ± 10% 50Hz)

2. Working environment: temperature -10 ℃ ～+40 ℃ relative humidity <85%(25 ℃) altitude <4000m

3. Device capacity: <1kva

4. Dimensions: 1410mm × 725mm × 1535mm

 

Fourth, the basic equipment of the device

 

1. Power control panel (aluminum panel)

(1) AC power supply (with leakage protection measures)

Provide three -phase AC power supply (380V)

(2) Personal safety protection system

The screen is equipped with a voltage leakage protection device. If there is a leakage in the screen or the strong power output, the alarm and cut off the power to ensure the safety of the experimental process.

There is a set of current leakage protectors on the screen. If there is a leakage in the control screen, the leakage current exceeds a cert--n value, that is, the power supply is cut off.

2. M--n order control and icon board (aluminum panel)

All the m--n order electrical appliances and action indicators of organic tools installed on the panel are performed on this panel. The indicator lights can indicate the corresponding movement of the machine tool.

The panel is printed with a T68 -type horizontal bed three -dimensional schematic diagram, which can intuitively see the outline of the T68 -type horizontal bed bed.
