Vacuum glove box is broadly applied in industries with higher needs for fuel purification. Even though the present-day glove box style and design is additional affordable and simple to work. However, the framework inside the glove box is challenging, there are quite a few critical elements, and the procedure is a little incorrect, which may induce loss to your experimental outcomes. This write-up introduces you how to accurately use the vacuum glove box, and the safeguards when novices operate the glove box.
One particular. Get the job done right before operation:
1. Look at if there is nitrogen in the nitrogen bottle. The nitrogen need to be changed in time. The output stress of nitrogen is set to .4mpa.
two. Check whether the vacuum pump is turned on normally.
3. Look at whether the circulation in the glove box is open up. (Purification column-I or purification column-II should open up just one of them)
4. Examine the higher restrict strain in the setting need to be +one, the lower restrict strain is
five. Verify no matter whether oxygen and dew level are ordinary (oxygen is below .1ppm, dew position is higher than -40)
6. The vacuum pump of the more than-bin ought to be in the generally open up state
two. Procedure notes:
1. The vacuum pump should really be held on for the duration of technique procedure.
2. When the oxygen concentration in the tank exceeds 200PPM, the gear routine maintenance personnel should be notified to work the procedure, if not the h2o and oxygen purification system will be damaged.
three. Right before setting up the cycle, verify whether or not the cupboard is in condition or regenerating. As the previously mentioned mentioned functions are in progress, it is certainly forbidden to cycle.
4 .Two purification columns are unable to be regenerated at the very same time.
A. Prior to 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.
