Vacuum glove box is widely employed in industries with superior specifications for fuel purification. Despite the fact that the recent glove box style is much more sensible and easy to run. On the other hand, the framework inside of the glove box is complex, there are numerous crucial components, and the operation is marginally improper, which may well result in decline to your experimental final results. This posting introduces you how to the right way use the vacuum glove box, and the safety measures when novices function the glove box.

A single. Do the job ahead of procedure:

one. Test if there is nitrogen in the nitrogen bottle. The nitrogen should be replaced in time. The output pressure of nitrogen is established to .4mpa.

two. Examine whether the vacuum pump is turned on commonly.

three. Verify whether the circulation in the glove box is open up. (Purification column-I or purification column-II ought to open one particular of them)

4. Verify the higher restrict tension in the placing need to be +1, the lower restrict pressure is

five. Check out regardless of whether oxygen and dew point are normal (oxygen is down below .1ppm, dew place is over -40)

six. The vacuum pump of the around-bin should be in the generally open point out

two. Operation notes:

one. The vacuum pump need to be retained on throughout system operation.

two. When the oxygen concentration in the tank exceeds 200PPM, the tools upkeep personnel should really be notified to function the process, usually the water and oxygen purification program will be destroyed.

3. Ahead of setting up the cycle, check out irrespective of whether the cupboard is in problem or regenerating. As the over talked about functions are in progress, it is definitely forbidden to cycle.

4 .Two purification columns can't be regenerated at the identical time.

A. Prior to regeneration, make sure that the glove box has been cleaned with inert fuel (H2O <200ppm) to ensure sufficient supply of regeneration gas. The regeneration gas pressure is 0.06-0.08mpa.

B. Before starting regeneration, please make sure that the corresponding purification column circulation is closed.

C. The regeneration process takes 24 hours. Once the execution cannot be disconnected, the regeneration gas should be passed 3-6 hours after the regeneration starts. Pay attention to the amount of regeneration gas, adjust the pressure of the regeneration gas appropriately, and ensure the sufficient supply of regeneration gas in these 3 hours. After 6 hours the regeneration origin can be turned off.

D. The vacuum pump cannot be turned off during the regeneration process. Do not touch the top of the purification column to prevent burns.

E. Once the regeneration is terminated unexpectedly, please ensure that the regeneration and circulation of the purification column cannot be restarted within 12 hours or the equipment will be damaged.

5. Care should be taken to protect the work gloves from being damaged during the operation.
