Safety measures when running the Nichwell glove box

Vacuum glove box is commonly utilized in industries with high needs for fuel purification. Even though the existing glove box layout is a lot more realistic and easy to work. Nonetheless, the structure inside the glove box is difficult, there are a lot of important components, and the procedure is somewhat inappropriate, which may possibly lead to loss to your experimental final results. This post introduces you how to accurately use the vacuum glove box, and the precautions when novices function the glove box.


1. Perform prior to operation:


1. Check if there is nitrogen in the nitrogen bottle. The nitrogen need to be changed in time. The output force of nitrogen is established to .4mpa.


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


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


four. Check the upper restrict force in the environment need to be +1, the reduce restrict stress is


5. Check whether oxygen and dew point are typical (oxygen is beneath .1ppm, dew position is over -40)


six. The vacuum pump of the above-bin need to be in the typically open up state


two. Operation notes:


one. The vacuum pump should be stored on throughout technique procedure.


2. When glove box manufacturers in the tank exceeds 200PPM, the equipment routine maintenance personnel ought to be notified to function the program, otherwise the drinking water and oxygen purification program will be broken.


three. Ahead of starting the cycle, examine whether the cabinet is in issue or regenerating. As the previously mentioned mentioned operations are in development, it is definitely forbidden to cycle.


four .Two purification columns cannot be regenerated at the identical time.

A. Just before regeneration, ensure that the glove box has been cleaned with inert gasoline (H2O &lt;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.
