Precautions When Running The Glove Box
Vacuum glove box is commonly applied in industries with higher necessities for fuel purification. Whilst the latest glove box style and design is additional fair and quick to operate. Nonetheless, the structure within the glove box is sophisticated, there are quite a few significant areas, and the procedure is marginally improper, which may perhaps result in reduction to your experimental results. This report introduces you how to appropriately use the vacuum glove box, and the safety measures when novices function the glove box.
A person. Work right before procedure:
one. Look at if there is nitrogen in the nitrogen bottle. The nitrogen need to be changed in time. The output pressure of nitrogen is set to .4mpa.
2. Examine no matter if the vacuum pump is turned on normally.
three. Verify regardless of whether the circulation in the glove box is open up. (Purification column-I or purification column-II should open up a person of them)
four. Look at the higher limit pressure in the setting ought to be +one, the decrease limit force is
five. Examine whether oxygen and dew issue are usual (oxygen is under .1ppm, dew level is earlier mentioned -forty)
six. The vacuum pump of the over-bin must be in the commonly open condition
two. Procedure notes:
one. The vacuum pump must be saved on throughout method procedure.
two. When the oxygen focus in the tank exceeds 200PPM, the devices maintenance staff need to be notified to run the process, otherwise the h2o and oxygen purification technique will be damaged.
3. Just before starting off the cycle, test whether the cabinet is in condition or regenerating. As the earlier mentioned talked about operations are in development, it is completely forbidden to cycle.
4 .Two purification columns cannot be regenerated at the very same time.
A. Ahead of 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.
