Equipment usage and main functions:

On the premise that the pressure P of the cross section of the coal sample is 9.8 * 104pa, which meets the test requirements, the main part of the equipment changes the traditional pressure mode of lever structure to the vertical pressure mode, which saves the steps of adjusting the lever level in the test preparation stage, and greatly reduces the size of the equipment. The automatic lifting weight function is added to improve the automation level of the equipment. The connection mode between the top rod of the heavy weight and the pressure plate is slot type, which saves the action of pulling the pin. The arrangement of furnace bricks and coal cups is changed from the front and back arrangement to the left and right arrangement. In the past, due to the structural reasons, it is difficult to adjust the probe alignment and gas pipe alignment of the rear furnace. After the furnace bricks are changed to the left and right arrangement, it is convenient for the test operation of the rear furnace and the installation, commissioning and maintenance of the equipment. The adjustment mode of the manipulator is changed from the left and right rotating arm to the transverse arm, the structure of the pressure plate is changed, and the alignment device is added to the coal cup to reduce the difficulty of the probe alignment of the manipulator.

Features and performance:

•The control software is based on Windows operating platform, which can automatically and accurately control the heating rate;

•Automatically record the temperature rise curve and coal sample volume change curve;

•The manipulator automatically detects and records the data of the upper and lower layers of the gum layer, and automatically calculates the final shrinkage X value and the maximum thickness Y value of the gum layer;

•Software real-time monitoring volume curve and intelligent judgment of its type, and then according to the national standard curve type of focal rules for accurate focal detection. The manipulator has the function of fast and slow down, and can detect the coke in time for the coal sample whose volume curve drops rapidly;

•The main engine adds the function of automatic lifting mound;

•Automatic generation of test report, support test report printing, historical data query, test data export to excel file, etc.

The main technical parameters:

• Y value measurement accuracy:when Y<20mm,△Y<1mm;Y>20mm,△Y<2m;

X value measurement accuracy:△X<3mm;

• Setting temperatuer/time:0~250~730/0~30~190min;

• Heating rate:250℃ within 30 min, 250-730℃ in 30-190 min, and heating rate ±3℃/min
