KDDL-8000W fully automatic sulfur analyzer sulfur quality inspection equipment

Product Overview

KDDL-8000W fully automatic sulfur analyzer sulfur quality inspection equipmentIt is one of the various fully automatic and diverse sulfur determination instruments independently developed by our company. It has a continuous automatic sample feeding structure with low failure rate. When 20 coal samples are put in at once, the instrument will automatically complete the testing of all samples, and new coal samples can be added cyclically at any time during the process. This instrument uses a dedicated ceramic boat for this machine.

Performance characteristics

1. An automatic sample feeding and dropping device with high stability, capable of placing 25 samples at once without the need for manual operation. If 25 samples are tested, they can be added without restriction after 6 minutes without stopping the experiment.

2. Adopting an integrated structure, the automatic sample feeding and dropping device, cracking furnace, electrolytic cell, agitator, sample feeding mechanism, air purification system and other components are assembled in the entire box, making the instrument structure compact and aesthetically pleasing.

3. The measurement time can be automatically determined based on different coal samples, which is about 5 minutes. System errors are automatically corrected by software, and the measurement results are superior to national standards, with good repeatability and high accuracy.

4. Adopting PID (proportional, derivative, integral) temperature control algorithm, accurate temperature control and fast heating speed. Adopting a contactless switch with hardware over temperature protection and electrolyte backflow prevention measures, it is safe and reliable to use.

5. Adopting an innovative multi-point dynamic system calibration method to ensure higher accuracy in high, medium, and low sulfur content.

6. The program controls automatic temperature rise, temperature control, sample delivery, sample return, electrolysis, and calculation. The results are automatically saved, printed, and the operator's work is only to weigh the sample. The software adopts a dynamic graphical interface, which is intuitive and easy to operate.

7. The adopted serial port technology adapts to the new development of computer technology and can be combined with other instruments to form a comprehensive testing instrument, implementing multi control for one machine.

8. The testing software fully supports the Windows platform, with better stability, can be connected to electronic scales, and can achieve remote data sharing through networking.

Precautions

1. The operation of microcomputers should follow the computer operating procedures.2. The bias voltage is too high. When reducing the bias voltage, the sampling resistor of the instrument should be reduced first, and then the voltage should be appropriately reduced by 1-5mV each time, not too much at once. The bias voltage collected after pressing the balance button is slightly higher than the actual bias voltage of the electrolytic cell, which is a normal phenomenon. If there is a downward drift phenomenon when the instrument is running on the baseline, the bias voltage can be readjusted. 3. When the instrument has abnormal bias voltage, carefully check whether the wiring is reversed, whether there is virtual soldering, and whether there are bubbles on the side arm of the electrolytic cell. 4. Be careful when opening and closing the mixer door, and do not vibrate too much to damage the cracking tube or electrolytic cell. 5. The gas pressure should not be too high, generally a partial pressure of 0.2 MPa is sufficient. 6. Some samples are not suitable for Coulomb analysis and should not contaminate the cracking tube and electrolytic cell. 7. After multiple samples are made, the electrolytic cell should be rinsed with fresh electrolyte to prevent contamination, and the cracking tube should be backfired after a period of time. 8. The electrolytic cell cannot be heated by the heating belt without gas connection! 9. After completing the analysis, wait until the temperature of the cracking furnace drops below 300 ° C before turning off the fan to avoid damaging the instrument due to high temperature!

KDDL-8000W fully automatic sulfur analyzer sulfur quality inspection equipmentReasons for electrolyte turbidity

1. It may be that the electrodes of the electrolytic cell are contaminated. We just need to use degreasing and alcohol to wipe and clean the electrode pads.

2. If the contact of the electrolytic cell joint is poor, the electrode or its connection of the electrolytic cell will be broken. We need to observe whether the connection on the electrode is tightened before reconnecting.

3. If the stirring speed is slow during high sulfur conditions, the height of the electrolytic cell needs to be adjusted. Long term use causes the agitator in the electrolytic cup to become thinner, so replacing the agitator is sufficient.

4. The electrolyte is no longer effective, please replace the electrolyte.

5. If there is any black scale on the sintered melting plate and inlet pipe in the electrolytic cup, immediately use a cleaning solution to remove it.
