Vacuum glove box is commonly utilized in industries with high demands for fuel purification. Despite the fact that the current glove box design and style is much more realistic and simple to run. Nonetheless, the framework within the glove box is complex, there are a lot of crucial elements, and the procedure is somewhat poor, which may result in loss to your experimental benefits. This report introduces you how to correctly use the vacuum glove box, and the safeguards when novices function the glove box.

1. Perform ahead of operation:

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

two. Verify no matter whether the vacuum pump is turned on usually.

3. Verify whether or not the circulation in the glove box is open up. (Purification column-I or purification column-II ought to open a single of them)

4. Check out the upper limit stress in the location ought to be +one, the decrease limit pressure is


five. Verify no matter whether oxygen and dew level are typical (oxygen is below .1ppm, dew stage is over -forty)

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

two. Procedure notes:

one. The vacuum pump must be stored on during method procedure.

2. When the oxygen concentration in the tank exceeds 200PPM, the tools upkeep staff ought to be notified to function the method, normally the water and oxygen purification program will be ruined.

3. Ahead of starting the cycle, verify whether or not the cabinet is in situation or regenerating. As the over talked about operations are in progress, it is definitely forbidden to cycle.

four .Two purification columns can't be regenerated at the exact same time.

A. Before regeneration, make certain that the glove box has been cleaned with inert gasoline (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.
