Vacuum glove box is commonly made use of in industries with substantial needs for fuel purification. Despite the fact that the latest acrylic glove box box design is more fair and simple to run. On the other hand, the structure inside the glove box is intricate, there are quite a few significant parts, and the operation is somewhat incorrect, which could trigger reduction to your experimental success. This article introduces you how to accurately use the vacuum glove box, and the safety measures when novices work the glove box.

One. Get the job done prior to operation:

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

two. Examine irrespective of whether the vacuum pump is turned on ordinarily.

3. Examine whether or not the circulation in the glove box is open. (Purification column-I or purification column-II ought to open one particular of them)

4. Examine the upper limit force in the location must be +1, the decrease restrict force is

five. Look at irrespective of whether oxygen and dew position are normal (oxygen is down below .1ppm, dew level is previously mentioned -40)

6. The vacuum pump of the above-bin ought to be in the normally open point out

two. Procedure notes:

1. The vacuum pump must be held on throughout program operation.

2. When the oxygen focus in the tank exceeds 200PPM, the tools maintenance personnel need to be notified to work the procedure, usually the drinking water and oxygen purification technique will be ruined.

three. Prior to setting up the cycle, check whether or not the cupboard is in issue or regenerating. As the higher than mentioned functions are in progress, it is unquestionably forbidden to cycle.

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

A. In advance of regeneration, ensure 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.
