Glove box regeneration actions

one) Regeneration gas: a combination of hydrogen and inert gas (hydrogen accounts for 5% -10%)

2) Amount: 40L fuel cylinder 10Mpa

three) Regenerative fuel stress: .05Mpa (the fuel use for each 50 percent hour in the state of .05Mpa is that the cylinder strain drops by 1.5Mpa. If it exceeds one.5Mpa, gloveboxes the pressure of the stress regulator’s timetable will be decreased, if it is less than 1.5Mpa Maximize the tension of the pressure regulator routine)

4) Process: three hrs heating-three hours heating and air flow-three hours vacuuming-1 hour pumping-ten several hours cooling

5) Measures:

① Join the regeneration gasoline (check out the pipeline for leaks right after relationship: soon after connecting, open up the main valve of the stress lowering valve to the greatest, open up the auxiliary meter to .1Mpa, convert off the most important valve, wait fifteen minutes, if the tension of the auxiliary meter remains at .one Mpa remains unchanged, indicating no air leakage)

②Set the tension of the auxiliary gauge of the pressure lessening valve to .1Mpa (the tension for the duration of ventilation is about .06-.08MPa)

③ Shut the cycle and analyzer

④Turn on the vacuum pump

⑤ Begin regeneration

⑥ The new application ends at 20h (thoroughly clean right before cleaning, drinking water and oxygen index <200ppm).

6) Note: Do not cut off the power and gas during the regeneration process (especially the first 6 hours)! Some pressure reducing valves are not allowed, and the pressure needs to be adjusted appropriately to ensure continuous ventilation for 3 hours!

7) Observation: whether the regeneration gas flowmeter shows about 20L / min, otherwise adjust the pressure of the pressure reducing valve.
