Vacuum glove box is broadly made use of in industries with significant requirements for gasoline purification. Though the recent glove box design and style is extra sensible and straightforward to function. On the other hand, the framework inside the glove box is complicated, there are numerous important areas, and the operation is a little bit improper, which may perhaps bring about decline to your experimental results. This report introduces you how to properly use the vacuum glove box, and the safety measures when novices operate the glove box.

Just one. Do the job just before procedure:

1. Test if there is nitrogen in the nitrogen bottle. The nitrogen must be changed in time. The output tension of nitrogen is established to .4mpa.

2. Verify whether the vacuum pump is turned on ordinarily.

three. Test irrespective of whether the circulation in the glove box is open up. (Purification column-I or purification column-II must open a single of them)

4. Look at the upper restrict stress in the environment must be +one, the reduce limit tension is

five. Examine whether or not oxygen and dew stage are usual (oxygen is down below .1ppm, dew issue is higher than -40)

six. The vacuum pump of the above-bin should be in the commonly open state

two. Procedure notes:

one. The vacuum pump need to be held on in the course of program procedure.

2. When the oxygen focus in the tank exceeds 200PPM, the devices upkeep staff really should be notified to run the system, usually the drinking water and oxygen purification program will be broken.

three. Before starting the cycle, check out regardless of whether the cupboard is in ailment or regenerating. As the above described functions are in development, it is certainly forbidden to cycle.

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

A. Just before regeneration, assure that the glove box has been cleaned with inert gasoline (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.
