SH500Automatic oxygen bomb calorimeter

SH500Automatic oxygen bomb calorimeter

The automatic calorimeter is suitable for measuring coal, coke, petroleum, cement raw materials, bricks and other solids or liquids, etc. in industries such as electricity, coal, metallurgy, petrochemical, quality inspection, environmental protection cement, papermaking, geological survey, scientific research institutes, etc. The calorific value of combustibles meets the requirements of GB/T213-2008 "Coal Calorimetry Method".

Working principle:

The use of advanced SCM system, fully automated operation, artificial only need to do the weighing, loading and oxygenation, the instrument automatically complete the quantitative water injection, automatic mixing, ignition, output print results, drainage and other work

Calorimeter calorimeter system, in addition to water absorption of heat, the oxygen bomb, inner cylinder, thermometer and stirrer, etc. will absorb heat, and the respective endothermic situation is not the same, a variety of factors are more complex and can not rely on simple Mathematical calculations can only use the reference of known calorific value, such as benzoic acid, to actually calibrate the calorie required for every 1°C increase in the calorimetric system temperature, that is, to calibrate the heat capacity of the calorimeter.

Features:

Super large capacity water tank, suitable for large batch continuous 24 hours experiment

Human-computer interaction friendly interface, large-screen Chinese characters screen display time and test process, that is, learning to use with the post-experimental conversion high and low heat function

Calorimeter product replacement is rapid, and there has been a highly automated calorimeter that automatically oxygenates, automatically lifts oxygen bombs, and automatically releases oxygen bomb exhaust gas after the experiment is completed.

1. The user only needs to install the aerobic bomb during operation, and the remaining connected electronic balance reads the weight of the sample, charges oxygen, raises and lowers the oxygen bomb, identifies the oxygen bomb, quantifies the amount of water in the inner cylinder, ignites, completes the test, oxygen bomb deflation, and experiment Results statistics and other processes can be fully automated.

2. Automatically adjust the temperature difference between the inner and outer cylinders to ensure that the temperature of the inner cylinder is about 1K higher than that of the outer cylinder at the end of the cylinder. This fully complies with the requirements of Section 8.2.4 of the national standard, and the test results are stable for a long time.

3. The ability to perform experiments for more than 72 hours continuously solves the technical problem that the calorimeter with no cooling device needs to suspend the experiment due to the rise in water temperature (overshoot) of the outer cylinder.

4. The use of imported mechanical components, automatic oxygenation, automatic deflation, automatic lifting and other oxygen bomb movements.

5. Compressor refrigeration and special heating devices are used to achieve automatic control of the external cylinder water temperature, and the temperature control accuracy meets the requirements of the national standard 7.1.4 (±0.1K).
