Vacuum glove box is commonly used in industries with superior necessities for fuel purification. Despite the fact that the existing glove box style is a lot more fair and gloveboxes uncomplicated to work. Nevertheless, the framework within the glove box is challenging, there are several significant parts, and the operation is a bit poor, which might bring about loss to your experimental outcomes. This report introduces you how to accurately use the vacuum glove box, and the safeguards when novices operate the glove box.
A single. Operate in advance of procedure:
1. Verify if there is nitrogen in the nitrogen bottle. The nitrogen need to be replaced in time. The output tension of nitrogen is established to .4mpa.
two. Verify no matter whether the vacuum pump is turned on normally.
three. Examine irrespective of whether the circulation in the glove box is open. (Purification column-I or purification column-II should open up one of them)
4. Test the higher limit strain in the placing ought to be +one, the decreased limit stress is
five. Verify irrespective of whether oxygen and dew level are ordinary (oxygen is under .1ppm, dew position is over -forty)
six. The vacuum pump of the about-bin should really be in the typically open condition
two. Procedure notes:
1. The vacuum pump need to be kept on throughout program operation.
two. When the oxygen concentration in the tank exceeds 200PPM, the equipment upkeep personnel need to be notified to work the process, or else the drinking water and oxygen purification process will be destroyed.
three. Ahead of starting off the cycle, check irrespective of whether the cabinet is in affliction or regenerating. As the over mentioned operations are in progress, it is absolutely forbidden to cycle.
4 .Two purification columns are not able to be regenerated at the very same time.
A. In advance of regeneration, make certain that the glove box has been cleaned with inert fuel (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.
