Safety Measures When Operating The Etelux Glove Box
Vacuum glove box is greatly made use of in industries with high demands for gasoline purification. Despite the fact that the existing glove box style and design is additional fair and straightforward to run. Nevertheless, the framework within the glove box is intricate, there are quite a few critical pieces, and the procedure is somewhat improper, which may well result in reduction to your experimental results. This post introduces you how to correctly use the vacuum glove box, and the precautions when novices function the glove box.
A single. Function in advance of operation:
one. Check out if there is nitrogen in the nitrogen bottle. The nitrogen should be changed in time. The output stress of nitrogen is set to .4mpa.
two. Examine no matter whether the vacuum pump is turned on commonly.
3. Verify whether the circulation in the Glove Box Accessories box is open up. (Purification column-I or purification column-II ought to open just one of them)
4. Test the higher restrict tension in the setting must be +1, the reduced limit stress is
5. Look at regardless of whether oxygen and dew issue are regular (oxygen is below .1ppm, dew point is over -40)
six. The vacuum pump of the about-bin really should be in the generally open up point out
two. Procedure notes:
1. The vacuum pump ought to be retained on through technique procedure.
two. When the oxygen focus in the tank exceeds 200PPM, the machines routine maintenance personnel should really be notified to operate the process, normally the drinking water and oxygen purification method will be ruined.
three. Ahead of setting up the cycle, check out whether or not the cupboard is in problem or regenerating. As the higher than outlined functions are in progress, it is absolutely forbidden to cycle.
four .Two purification columns can't be regenerated at the exact same time.
A. Right before regeneration, be certain 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.
