Safety Measures When Working The Glove Box
Vacuum glove box is widely used in industries with significant needs for fuel purification. Even though the latest glove box layout is additional affordable and quick to work. Even so, the framework within the glove box is complicated, there are several essential sections, and the procedure is slightly poor, which could trigger reduction to your experimental success. This post introduces you how to correctly use the vacuum glove box, and the precautions when novices work the glove box.
One. Perform in advance of procedure:
1. Check if there is nitrogen in the nitrogen bottle. The nitrogen need to be replaced in time. The output pressure of nitrogen is established to .4mpa.
two. Examine no matter whether the vacuum pump is turned on normally.
three. Check no matter if the circulation in the glove box is open. (Purification column-I or purification column-II should open just one of them)
four. Verify the upper limit force in the placing should be +1, the lessen limit tension is
five. Examine irrespective of whether oxygen and dew position are usual (oxygen is below .1ppm, dew place is above -40)
six. The vacuum pump of the about-bin must be in the normally open up state
two. Procedure notes:
one. The vacuum pump need to be saved on all through system operation.
2. When the oxygen concentration in the tank exceeds 200PPM, the gear servicing personnel need to be notified to work the technique, usually the water and oxygen purification procedure will be destroyed.
three. Just before starting off the cycle, check out regardless of whether the cupboard is in situation or regenerating. As the previously mentioned pointed out functions are in progress, it is totally forbidden to cycle.
4 .Two purification columns cannot be regenerated at the identical time.
A. Just before regeneration, gloveboxes ensure 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.
