Safeguards When Functioning The Glove Box
Vacuum glove box is greatly utilised in industries with superior necessities for fuel purification. Though the existing glove box layout is far more reasonable and effortless to work. Nonetheless, the structure inside the glove box is difficult, there are quite a few critical parts, and the procedure is a little poor, which may perhaps bring about decline to your experimental effects. This article introduces you how to effectively use the vacuum glove box, and the precautions when novices work the glove box.
A person. Function right before procedure:
1. Look at if there is nitrogen in the nitrogen bottle. The nitrogen ought to be replaced in time. The output tension of nitrogen is set to .4mpa.
two. Check out no matter whether the vacuum pump is turned on usually.
three. Check no matter whether the circulation in the glove box is open up. (Purification column-I or purification column-II should really open a person of them)
4. Check the higher restrict force in the environment really should be +1, the decrease restrict stress is
five. Verify whether oxygen and dew point are standard (oxygen is underneath .1ppm, dew level is higher than -40)
six. The vacuum pump of the more than-bin really should be in the ordinarily open up point out
two. Operation notes:
1. The vacuum pump should really be saved on all through program operation.
2. When the oxygen concentration in the tank exceeds 200PPM, the products upkeep staff really should be notified to operate the procedure, or else the water and oxygen purification technique will be harmed.
three. Right before starting off the cycle, look at no matter whether the cupboard is in issue or regenerating. As the over outlined operations are in progress, it is unquestionably forbidden to cycle.
4 .Two purification columns can't be regenerated at the similar time.
A. Before 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.
