Vacuum glove box is greatly used in industries with substantial specifications for fuel purification. Even though the present glove box design and innovative technologies glovebox style is far more acceptable and quick to operate. Having said that, the composition inside the glove box is challenging, there are a lot of crucial pieces, and the procedure is slightly poor, which might trigger loss to your experimental benefits. This article introduces you how to properly use the vacuum glove box, and the safety measures when novices run the glove box.

A single. Do the job just before procedure:

one. Test if there is nitrogen in the nitrogen bottle. The nitrogen really should be changed in time. The output tension of nitrogen is set to .4mpa.

two. Check no matter whether the vacuum pump is turned on commonly.

3. Verify irrespective of whether the circulation in the glove box is open. (Purification column-I or purification column-II must open up one particular of them)

four. Check the higher restrict stress in the placing really should be +one, the reduce limit tension is

five. Verify whether oxygen and dew position are standard (oxygen is below .1ppm, dew issue is above -forty)

six. The vacuum pump of the over-bin need to be in the ordinarily open point out

two. Procedure notes:

1. The vacuum pump ought to be retained on for the duration of technique procedure.

2. When the oxygen concentration in the tank exceeds 200PPM, the machines routine maintenance personnel ought to be notified to work the system, otherwise the h2o and oxygen purification system will be weakened.

3. In advance of starting off the cycle, check out irrespective of whether the cupboard is in problem or regenerating. As the previously mentioned mentioned operations are in development, it is absolutely forbidden to cycle.

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

A. Right before regeneration, assure 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.
