Kzch-8 fast automatic coal hydrogen detector
Product introduction:
Kzch-8 type fast automatic hydrogen detector is mainly used to determine the hydrogen content in organic matter in coal and other solid materials. It is the necessary experimental instrument for coal, electric power, metallurgy, coking products and other departments. At the same time, it is also widely used in chemical industry, commodity inspection and other units. The whole testing process is controlled by single-chip microcomputer, and the test data are corrected and processed by the single-chip microcomputer. The milligram number of hydrogen in the determined substance is displayed digitally, and the final result of determination can be displayed, and the hydrogen value can be printed out at the same time. The time of each sample is about 10-15min, and the accuracy and accuracy of the determination results are better than those of GB / t15460-2003. Compared with the three-stage furnace combustion method, the instrument has the advantages of rapid determination, accurate results, simple operation, high degree of automation, touch keyboard to input various data, printer to print the final results, small size, light weight and so on. It is an ideal hydrogen measuring instrument in the laboratory at present, and can also measure carbon by absorption method.

Performance features:
The instrument has the advantages of rapid determination, accurate results, simple operation and high degree of automation. Digital display of hydrogen in the determination of milligrams, automatic printing of hydrogen content. It has the advantages of novel appearance design, convenient operation, less space for use and more convenient maintenance. The instrument can also measure the carbon content in coal and other solid materials.

Main technical indicators:
1. Determination range: hydrogen: 0-20% carbon: 0-100%
2. Power supply: 220 V ± 10% 50 Hz
3. Temperature control: 850 ℃± 10 ℃ 300 ℃± 10 ℃
4. Electrolytic voltage: coating electrolytic voltage: 10V
Working electrolytic voltage: 24 V
5. Electric current: electrolysis current > 600mA
Terminal current < 70ma
6. Determination time: about 10-15min, 30 seconds at 300 ℃
At 500 ℃ for 2 min and 850 ℃ for 10 min.
7. Stability of Coulomb integrator: linearity ± 0.1%
8. Allowable error: hydrogen: ≤ 0.15% carbon: ≤ 0.50%
9. Test sample: the weight of the coal sample whose particle size is less than 0.2mm and has reached the air drying state is about 70mg-75mg.

working principle:
The whole process of kzch-8 type fast automatic hydrogen detector is controlled by single chip microcomputer. After the instrument is powered on, the date, sample weight, hydrogen blank value and moisture value of analysis sample are input through the keyboard. After pressing the hydrogen measuring key, the motor will rotate forward to drive the sample bar forward. When it is pushed to 300 ℃, the motor will stop running and delay for 30 seconds. Then it will enter 500 ℃ by microcomputer Make the motor stop running and delay for 2 minutes. Then the microcomputer sends a signal to make the motor forward to drive the sample bar to push forward the sample until it reaches 850 ℃. The microcomputer stops the motor and delays for 10 minutes. Then it sends a signal to reverse the motor to drive the sample feeding bar to pull the disk containing the sample to the original position. After the motor stops running, the alarm will give an alarm to indicate the test At the end of the whole process, the printer prints out the test data.

Instrument maintenance
1. The instrument should be protected from dust and corrosive gas, and should be used in a dry environment.
2. The instrument should be handled with care to prevent vibration damage.
3. Pay attention to the protection and cleaning of the electrolytic cell. If the hydrogen value of the system is found to be low, if there is no other error, the electrolytic cell should be treated.
4. Replace silicone rubber tube and gasket regularly.
5. If it is not used for a long time, the electrolytic cell shall be treated and calibrated with standard samples. Generally, the standard samples shall be used for calibration once a month.
6. The air tightness of the system should be checked frequently.
7. Pay attention to check the failure of Yao products.

Kzch-8 type fast automatic hydrogen detector adopts integrated design, which consists of purification system, control system, combustion conversion system, carbon measurement system and electrolytic cell, etc. the machine is controlled by single chip microcomputer, and the operation panel is shown in Fig. 1.
