Safeguards When Working The Etelux Glove Box
Vacuum glove box is extensively utilized in industries with significant specifications for gasoline purification. Though the current glove box design is additional fair and quick to function. Having said that, the framework inside the glove box is intricate, there are several critical elements, and the procedure is marginally incorrect, which could result in loss to your experimental final results. This write-up introduces you how to properly use the vacuum glove box, and the safety measures when novices function the glove box.
1. Function ahead of procedure:
one. Examine if there is nitrogen in the nitrogen bottle. The nitrogen should really be replaced in time. The output force of nitrogen is set to .4mpa.
two. Examine whether or not the vacuum pump is turned on generally.
three. Look at irrespective of whether the circulation in the glove box is open up. (Purification column-I or purification column-II ought to open up one of them)
four. Check the upper limit strain in the environment should really be +1, the decreased limit tension is
5. Check out no matter if oxygen and dew level are normal (oxygen is down below .1ppm, dew point is over -40)
six. The vacuum pump of the about-bin should really be in the typically open up point out
two. Operation notes:
one. The vacuum pump really should be held on throughout program procedure.
2. When the oxygen concentration in the tank exceeds 200PPM, the devices upkeep personnel ought to be notified to work the procedure, or else the drinking water and oxygen purification method will be broken.
three. Before setting up the cycle, examine regardless of whether the cupboard is in affliction or regenerating. As the previously mentioned described operations are in development, it is definitely forbidden to cycle.
four .Two purification columns are not able to be regenerated at the exact same time.
A. Before regeneration, be certain that the glove box has been cleaned with inert fuel (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.
