    one) Regeneration fuel: a mixture of hydrogen and inert gas (hydrogen accounts for five% -ten%)

    two) Amount: 40L gasoline cylinder 10Mpa

    3) Regenerative gasoline force: .05Mpa (the gas intake per 50 percent hour in the point out of .05Mpa is that the cylinder tension drops by 1.5Mpa. If it exceeds 1.5Mpa, the stress of the stress regulator’s program will be decreased, if it is significantly less than one.5Mpa Maximize the tension of the force regulator agenda)

    four) Procedure: 3 hours heating-three several hours heating and air flow-three hours vacuuming-1 hour pumping-ten hrs cooling

    five) Steps:

    ① Connect the regeneration fuel (test the pipeline for leaks just after link: soon after connecting, open the key valve of the force reducing valve to the optimum, open the auxiliary meter to .1Mpa, switch off the most important valve, wait around fifteen minutes, if the force of the auxiliary meter continues to be at .1 Mpa stays unchanged, indicating no air leakage)

    ②Set the pressure of the auxiliary gauge of the force lowering valve to .1Mpa (the stress all through air flow is about .06-.08MPa)

    ③ Shut the cycle and analyzer

    ④Turn on the vacuum pump

    ⑤ Begin regeneration

    ⑥ The new system finishes at 20h (clean before cleaning, water and vac glovebox 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.
