Safety Measures When Functioning The Glove Box
Vacuum glove box is greatly employed in industries with superior demands for gasoline purification. Whilst the present glove box design and style is much more reasonable and easy to run. Nevertheless, the framework inside the glove box is challenging, there are lots of important areas, and the procedure is a little poor, which might trigger reduction to your experimental success. This article introduces you how to appropriately use the vacuum glove box, and the safeguards when novices run the glove box.
1. Operate before operation:
one. Examine if there is nitrogen in the nitrogen bottle. The nitrogen need to be replaced in time. The output pressure of nitrogen is set to .4mpa.
2. Check irrespective of whether the vacuum pump is turned on usually.
three. Examine no matter if the circulation in the glove box is open. (Purification column-I or purification column-II need to open a single of them)
four. Examine the higher restrict strain in the environment need to be +one, the lessen restrict stress is
five. Test no matter whether oxygen and dew stage are standard (oxygen is below .1ppm, dew point is over -40)
6. The vacuum pump of the more than-bin should really be in the commonly open state
two. Procedure notes:
1. The vacuum pump must be held on in the course of technique procedure.
two. When the oxygen focus in the tank exceeds 200PPM, the devices upkeep personnel should really be notified to work the technique, if not the water and oxygen purification technique will be damaged.
3. Prior to starting up the cycle, look at no matter if the cupboard is in issue or regenerating. As the earlier mentioned stated operations are in development, it is unquestionably forbidden to cycle.
four .Two purification columns are not able to be regenerated at the same time.
A. In advance of regeneration, make sure that the glove box manufacturers 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.
