Introduction: The test device is used to test the thermophysical parameters of soils such as disturbed clay and sand, and is also suitable for the study of the heat transfer performance of solid powder materials. It is widely used in construction engineering and soil geology research. Refer to GB/T50123-1999 geotechnical test method standard. In addition to this method, specific heat capacity and thermal conductivity test methods are added. The system uses the host computer for data collection, automatic analysis and testing, data storage, report output, etc. The application of modern computer technology has reached a high level of reliability and accuracy of the system. It can also be applied to the analysis and test of the thermal conductivity of frozen soil after adding the freezing test box. Therefore, the system test device can accurately test the transfer performance parameters of soil and other powder materials. Technical features: 1. The experiment temperature is normal temperature, among which DRX-I-300B is an increased low temperature (negative temperature environment) system, which is used for negative temperature research and testing of thermophysical parameters of frozen soil and low temperature materials. DRX-I-300A is a high-temperature thermophysical parameter test of materials; DRX-I-300C is a material parameter test at room temperature. 2. The size of the sample box is: 250×250×250 (mm) or ¢50*50 (mm) 3. The experimental device is composed of a constant temperature system, a temperature measurement system, a sample box, and a computer test system. 4. The constant temperature box is in close contact with the sample box, and the two constant temperature boxes are provided with different circulating temperatures by the constant temperature circulating water tank. 5. The temperature measurement system uses a high-precision platinum resistance thermometer, connected to the data acquisition system, and realizes automatic testing and analysis through computer software, generates experimental reports, and automatically records and stores experimental data. 6. The heat source adopts direct current heating to ensure constant power. 7. The test temperature is accurate to 0.1°C/0.01°C, and the test result is accurate to three decimal places. 8. The system power supply is 220V/50HZ, and the total power consumption is not more than 1KW.
