Automatic Oxygen Bomb Calorimeter ZDHW-9L ASTM D240
Scope of application:
The automatic calorimeter is suitable for measuring the power,
coal, metallurgy, petrochemical, quality inspection, environmental
protection cement, papermaking, geological exploration, scientific
research institutes and other industrial sectors. Measuring the
calorific value of coal, coke, petroleum, cement, brick and other
solid or liquid combustibles, in line with the national standard
GB/T213-2008 "calculation method of coal calorific value".
Product advantages:
1. The environment adaptability is strong and the test results are
accurate and stable.
2. The experimental data full curve tracking function, can easily
view the temperature and time in the curve.
3. With instructions for operation, failure, etc., the experiment
ends with automatic voice report results.
4. The window display uses a 7.0-inch color LCD touch screen, the
display content is intuitive and easy to understand.
5. Simple and convenient, the control core uses ARM9
microprocessor, fast, real-time.
6. Reliability fault self-tuning function, the device has a variety
of protection functions.
7. Using internal and external tube photoelectric isolation, strong
anti-interference ability.
8. Internal loading has standards, instructions and common
troubleshooting methods.
Working principle:
Using advanced single-chip system, the operation is fully
automated. All the labor needs to do is to weigh, load and
oxygenate. The instrument automatically completes the quantitative
water injection, automatic mixing, ignition, output printing
results, drainage, etc.
In the calorimetric system of the calorimeter, in addition to the
heat absorbed by the water, the oxygen bomb, the inner cylinder,
the thermometer and the agitator absorb heat, and the respective
heat absorption conditions are different. Various factors are
complicated, and it is impossible to rely on simple Mathematical
calculations can only use the reference of known calorific value,
such as benzoic acid, to actually calibrate the heat absorbed by
the calorimeter system for every 1 °C increase, that is, to
calibrate the calorimeter's heat capacity.
Features:
Ultra-large capacity water tank for large batch continuous 24 hour
experiment
1. The user only needs to install the oxygen bomb when the user
operates, and the remaining electronic balance is used to read the
sample weight, oxygen, oxygen bomb, oxygen bomb, quantitative inner
cylinder water, ignition, completion test, oxygen bomb deflation,
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 inner cylinder is
about 1K higher than the outer cylinder temperature at the end
point, which fully meets the requirements of the national standard
8.2.4, and the test results are stable for a long time.
3. It can carry out experiments for more than 72 hours, which
solves the technical problem that the calorimeter without cooling
device needs to suspend the experiment due to the increase of the
outer cylinder water temperature (overshoot).
4. Imported mechanical parts, automatic oxygenation, automatic
deflation, automatic lifting oxygen bombs and other sports.
5. The compressor cooling and special heating device are adopted to
realize the automatic control of the water temperature of the outer
cylinder, and the temperature control accuracy meets the
requirements of the national standard 7.1.4 (±0.1K).
