Safeguards When Working The Glove Box
Vacuum vac glove box box is commonly made use of in industries with substantial needs for gasoline purification. Even though the current glove box style is extra acceptable and simple to operate. Even so, the construction inside of the glove box is challenging, there are many essential components, and the operation is a little bit incorrect, which may well lead to reduction to your experimental outcomes. This report introduces you how to effectively use the vacuum glove box, and the safeguards when novices run the glove box.
One. Function before operation:
one. Verify if there is nitrogen in the nitrogen bottle. The nitrogen must be replaced in time. The output strain of nitrogen is set to .4mpa.
2. Test no matter if the vacuum pump is turned on ordinarily.
three. Check regardless of whether the circulation in the glove box is open. (Purification column-I or purification column-II must open a single of them)
4. Look at the upper restrict tension in the location ought to be +one, the reduced limit tension is
5. Check out no matter whether oxygen and dew point are usual (oxygen is beneath .1ppm, dew place is earlier mentioned -forty)
six. The vacuum pump of the more than-bin really should be in the normally open up point out
two. Procedure notes:
1. The vacuum pump need to be saved on during program operation.
two. When the oxygen focus in the tank exceeds 200PPM, the gear routine maintenance staff should be notified to function the method, usually the h2o and oxygen purification system will be destroyed.
three. Right before setting up the cycle, check out no matter whether the cabinet is in ailment or regenerating. As the previously mentioned stated operations are in progress, it is completely forbidden to cycle.
four .Two purification columns can not be regenerated at the exact time.
A. Prior to regeneration, guarantee 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.
