Safeguards when running the Nichwell glove box
Vacuum glove box is broadly utilized in industries with large requirements for gasoline purification. Although the existing glove box layout is more realistic and effortless to run. However, the construction within the glove box is challenging, there are several critical parts, and the operation is slightly poor, which might lead to reduction to your experimental benefits. This write-up introduces you how to properly use the vacuum glove box, and the precautions when novices work the glove box.

One particular. Function ahead of procedure:

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

2. Check whether or not the vacuum pump is turned on generally.

3. Check out regardless of whether the circulation in the glove box is open. (Purification column-I or purification column-II ought to open a single of them)

four. Verify the upper restrict force in the location must be +1, the lower restrict force is

five. Examine regardless of whether oxygen and dew point are standard (oxygen is underneath .1ppm, dew level is earlier mentioned -forty)

six. glove box manufacturers usa,glove box manufacturers of the more than-bin must be in the usually open state

two. Procedure notes:

1. The vacuum pump must be kept on in the course of method operation.

2. When the oxygen focus in the tank exceeds 200PPM, the tools upkeep personnel need to be notified to run the program, normally the drinking water and oxygen purification technique will be broken.

3. Prior to beginning the cycle, check whether the cabinet is in issue or regenerating. As the earlier mentioned pointed out functions are in progress, it is absolutely forbidden to cycle.

four .Two purification columns can't be regenerated at the identical time.

A. Prior to regeneration, guarantee 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.
