Vacuum glove box is widely utilized in industries with high demands for fuel purification. Whilst the present glove box structure is far more reasonable and straightforward to operate. Nonetheless, the framework inside of the glove box is challenging, there are a lot of significant components, and the operation is a little improper, which might cause reduction to your experimental final results. This write-up introduces you how to the right way use the vacuum glove box, and the safeguards when novices work the glove box.
A single. Work right before procedure:
one. Test 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.
two. Check out no matter if the vacuum pump is turned on ordinarily.
3. Check whether or not the circulation in the glove box is open up. (Purification column-I or purification column-II really should open up one particular of them)
four. Look at the upper limit tension in the location should be +1, the lessen limit stress is
5. Examine no matter whether oxygen and dew stage are normal (oxygen is under .1ppm, dew stage is previously mentioned -40)
6. The vacuum pump of the in excess of-bin ought to be in the ordinarily open up condition
two. Operation notes:
1. The vacuum pump ought to be stored on throughout system procedure.
two. When the oxygen focus in the tank exceeds 200PPM, the machines routine maintenance staff should really be notified to work the procedure, or else the water and oxygen purification process will be broken.
three. Right before starting up the cycle, verify no matter whether the cabinet is in problem or regenerating. As the above outlined operations are in development, it is definitely forbidden to cycle.
4 .Two purification columns are unable to be regenerated at the similar time.
A. Before regeneration, assure 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.
