Vacuum glove box is greatly utilised in industries with significant specifications for fuel purification. While the present glove box design and style is far more affordable and effortless to function. Even so, the framework inside of the glove box is sophisticated, there are lots of critical sections, and the operation is marginally poor, which may well result in reduction to your experimental benefits. This article introduces you how to appropriately use the vacuum glove box, and the precautions when novices run the glove box.

One. Operate before procedure:

one. Verify if there is nitrogen in the nitrogen bottle. The nitrogen must be changed in time. The output strain of nitrogen is set to .4mpa.

2. Test no matter if the vacuum pump is turned on commonly.

3. Check out no matter if the circulation in the glove box is open up. (Purification column-I or purification column-II really should open up a single of them)

4. Check the higher limit strain in the setting ought to be +one, the decrease limit force is

5. Check out whether oxygen and dew point are regular (oxygen is underneath .1ppm, dew stage is previously mentioned -forty)

6. The vacuum pump of the about-bin must be in the ordinarily open condition

two. Procedure notes:

1. The vacuum pump should really be saved on all through method procedure.

2. When the oxygen concentration in the tank exceeds 200PPM, the products maintenance staff should be notified to function the system, in any other case the water and oxygen purification system will be ruined.

three. Before setting up the cycle, test no matter whether the cupboard is in issue or regenerating. As the previously mentioned talked about functions are in development, it is unquestionably forbidden to cycle.

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

A. Prior to regeneration, assure that the glove box has been cleaned with inert gas (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.
