Vacuum glove box is commonly utilized in industries with substantial specifications for fuel purification. Despite the fact that the current glove box design and style is a lot more realistic and effortless to work. Nevertheless, the structure within the glove box is sophisticated, there are quite a few critical sections, and the operation is slightly improper, which may perhaps cause reduction to your experimental results. This article introduces you how to the right way use the vacuum glove box, and the safeguards when novices operate the glove box.

1. Operate right before procedure:

1. Look at if there is nitrogen in the nitrogen bottle. The nitrogen should be changed in time. The output strain of nitrogen is set to .4mpa.

2. Verify regardless of whether the vacuum pump is turned on typically.

three. Test regardless of whether the circulation in the glove box is open up. (Purification column-I or purification column-II should open up a person of them)

four. Examine the upper limit strain in the setting should be +1, the decreased restrict pressure is

five. Look at whether or not oxygen and dew place are ordinary (oxygen is beneath .1ppm, dew stage is above -forty)

6. The vacuum pump of the more than-bin must be in the generally open up condition

two. Procedure notes:

1. The vacuum pump must be kept on for the duration of technique operation.

2. When the oxygen focus in the tank exceeds 200PPM, the devices upkeep staff need to be notified to run the system, usually the water and oxygen purification method will be ruined.

three. Ahead of starting off the cycle, look at regardless of whether the cabinet is in situation or regenerating. As the previously mentioned mentioned operations are in progress, it is definitely forbidden to cycle.

four .Two purification columns cannot be regenerated at the identical time.

A. In advance of regeneration, guarantee that the glove box has been cleaned with inert atmosphere glove box 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.
