Rolling bearing performance test analysis experiment table

This device can measure the load distribution, stress changes, and rolling bearing combination design experiments on the bearing elements during rolling bearing elements. The test is tested under the action of total radial load and axial load, and rolling bearing radial load distribution and changes, especially axis directional direction The effect of load on the radial load distribution of the rolling bearing; and the load distribution curve is made. Let students better master the work of rolling bearings and the measurement methods of related parameters, and improve the design ability of rolling bearings. Suitable for experimental teaching needs for the "Mechanical Design" course of mechanical majors in major universities.

I. Overview:

"Two -door refrigerator comprehensive tr--ning assessment device" is developed and designed for the development and design of the refrigeration, home appliance m--ntenance, various skills tr--ning and national vocational skills appr--sal departments for large and high school colleges. One -one, full -time layout of the tr--ning installation, has a comprehensive, intuitive, open and applied teaching tr--ning and assessment platform, allowing students to master the structure, principles and characteristics of direct cold/inter -cold refrigerators.

2. Technical parameters:

1. Input power supply: single -phase three -line AC220V ± 10% 50Hz 50Hz

2. Device capacity: <0.2kva

3. Dimensions: 600 × 600 × 1700mm

4. Refrigerator type: R600

5. Safety protection: It has leakage voltage and leakage current protection device, and safely meets national standards

2. Features:

1. The tr--ning device visually shows the system structure and working principles of direct cold/inter -cold refrigerators. You can clearly see the physical objects of the cooling circulation system and m--n components, which is convenient for teaching demonstration explanations and students' understanding of textbook knowledge. In addition, the pipeline has a visual liquid lens to observe the condition of the refrigerant; the high -pressure tube road is red and the low -pressure pipe road is the blue part.

2. The whole set of tr--ning devices integrates a str--ght cold and cold -type refrigerator. The entire refrigerator system is truly complete, the structure is clear and compact, which is consistent with the actual refrigerator refrigeration system and electrical system. At the same time, it can meet the requirements of direct -cooled and cold -type refrigerators.

3. The system adopts a real refrigeration unit (compressor, wing tablet duct evaporator, aluminum composite plate bloating evaporator, steel wire condenser, etc.)

4. The device is equipped with a direct -cooled/inter -cold refrigerator electrical control line wiring area, which can complete the operating mode of different startup methods, which is conducive to students applying theory to reality and cultivating students' actual operation ability.

5. Simple faults can be set, and students can determine the scope of the f--lure according to the cause of the f--lure of the process to analyze the cause of the f--lure. It is conducive to carrying out skills appr--sal and assessment.
