Vacuum glove box is broadly utilized in industries with substantial demands for fuel purification. Despite the fact that the existing glove box style is much more realistic and effortless to operate. However, the structure inside the glove box is challenging, there are a lot of crucial parts, and the operation is somewhat improper, which might result in reduction to your experimental benefits. This write-up introduces you how to appropriately use the vacuum glove box, and the precautions when novices run the glove box .

1. Work prior to operation:

1. Check out if there is nitrogen in the nitrogen bottle. The nitrogen must be replaced in time. The output stress of nitrogen is set to .4mpa.

2. Examine no matter whether the vacuum pump is turned on normally.

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



4. Check out the upper limit strain in the setting must be +1, the lower restrict stress is

5. Verify whether or not oxygen and dew point are typical (oxygen is underneath .1ppm, dew point is earlier mentioned -40)

6. The vacuum pump of the over-bin should be in the usually open point out

two. Operation notes:

1. The vacuum pump should be stored on throughout method procedure.

2. When the oxygen focus in the tank exceeds 200PPM, the tools routine maintenance personnel ought to be notified to operate the technique, otherwise the water and oxygen purification system will be damaged.

three. Prior to starting up the cycle, check whether the cabinet is in condition or regenerating. As the previously mentioned described operations are in progress, it is absolutely forbidden to cycle.

4 .Two purification columns are not able to be regenerated at the same time.

A. Prior to regeneration, guarantee 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.
