Safeguards When Functioning The Glove Box
Vacuum glove box is broadly utilised in industries with substantial necessities for fuel purification. While the present glove box style and gloveboxes design is a lot more acceptable and effortless to work. On the other hand, the structure inside of the glove box is difficult, there are numerous significant areas, and the operation is slightly inappropriate, which may well bring about reduction to your experimental success. This article introduces you how to effectively use the vacuum glove box, and the safeguards when novices work the glove box.
1. Function ahead of procedure:
one. Look at if there is nitrogen in the nitrogen bottle. The nitrogen must be replaced in time. The output force of nitrogen is established to .4mpa.
two. Verify regardless of whether the vacuum pump is turned on ordinarily.
3. Look at whether or not the circulation in the glove box is open up. (Purification column-I or purification column-II must open up just one of them)
four. Verify the higher limit tension in the environment need to be +one, the lower limit tension is
five. Examine no matter whether oxygen and dew level are typical (oxygen is below .1ppm, dew issue is above -forty)
six. The vacuum pump of the around-bin really should be in the typically open up condition
two. Operation notes:
one. The vacuum pump ought to be kept on all through procedure procedure.
two. When the oxygen focus in the tank exceeds 200PPM, the products maintenance staff should really be notified to function the process, or else the water and oxygen purification procedure will be destroyed.
3. Prior to commencing the cycle, check regardless of whether the cupboard is in issue or regenerating. As the previously mentioned talked about functions are in progress, it is certainly forbidden to cycle.
four .Two purification columns can not be regenerated at the very same time.
A. Prior to regeneration, be certain 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.
