High purity hydrogen generatorUsage method:

1. Power on and self-test

Power on: After connecting the power, check if the flow display is normal, and observe the pressure change by starting the switch.

Pressure monitoring: When the pressure gradually rises to the set value (such as 0.4Mpa), the digital display returns to zero (showing "000"), indicating that the instrument is normal. If the pressure does not meet the standard, the sealing of the gas path needs to be checked.

Flow calibration: The digital display of hydrogen production may fluctuate when first turned on, which is a normal phenomenon.

2. Gas path connection and usage

Connecting gas equipment: After shutting down, remove the hydrogen outlet sealing cap and connect it to the chromatograph and other equipment using a pipe with an outer diameter of 3mm to ensure that the sealing joint does not leak gas.

Flow matching: After starting the instrument, observe whether the flow display is consistent with the requirements of the gas equipment. If the flow exceeds the actual usage significantly, the machine needs to be shut down for leak detection and adjustment.

3. Monitoring during operation

Liquid level management: Regularly check the electrolyte level, replenish distilled water to the mark in a timely manner, and avoid the liquid level being too high or too low.

Silicone state: Observe whether the silicone in the drying tube changes color. If it changes color, it should be replaced or regenerated immediately to prevent moisture from affecting the purity of hydrogen gas.

Gas production stability: Ensure stable and non decaying gas production. If there are abnormal fluctuations, check the electrolytic cell or gas system.

4. Shutdown and shutdown

Shutdown sequence: First turn off the air circuit switch, then turn off the power switch to avoid damage to the equipment caused by sudden pressure changes.

Long term disuse: If the equipment is not used for a long time, the electrolyte should be drained and the interior cleaned to prevent residual corrosion of the components.

　　High purity hydrogen generatorSafety precautions:
