Vacuum glove box is broadly employed in industries with substantial necessities for gasoline purification. Although the current glove box style is far more fair and straightforward to run. Even so, the structure within the glove box is difficult, there are a lot of vital components, and the procedure is a bit incorrect, which could bring about loss to your experimental outcomes. This article introduces you how to correctly use the vacuum glove box, and the safeguards when novices function the glove box.

A single. Get the job done prior to operation:

one. Examine if there is nitrogen in the nitrogen bottle. The nitrogen need to be replaced in time. The output strain of nitrogen is established to .4mpa.

2. Check regardless of whether the vacuum pump is turned on usually.

3. Verify no matter if the circulation in the glove box is open. (Purification column-I or purification column-II must open a single of them)

four. Test the higher limit pressure in the location really should be +1, the lessen restrict strain is

five. Examine regardless of whether oxygen and dew stage are usual (oxygen is down below .1ppm, dew point is higher than -40)

6. The vacuum pump of the over-bin need to be in the usually open condition

two. Operation notes:

one. The vacuum pump should be retained on through system operation.

two. When the oxygen focus in the tank exceeds 200PPM, the devices routine maintenance personnel should be notified to work the program, in any other case the h2o and oxygen purification system will be ruined.

three. In advance of setting up the cycle, verify irrespective of whether the cabinet is in condition or regenerating. As the higher than pointed out functions are in development, it is definitely forbidden to cycle.

4 .Two purification columns simply cannot be regenerated at the very same time.

A. Ahead of regeneration, be certain 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.
