Etelux Glovebox (dustidea61)
Vacuum glove box is widely used in industries with substantial requirements for fuel purification. Despite the fact that the present glove box design is a lot more sensible and easy to operate. However, the composition inside the glove box is complex, there are many crucial areas, and the operation is a bit incorrect, which might result in decline to your experimental outcomes. This write-up introduces you how to accurately use the vacuum glove box, and the safeguards when novices run the glove box.
A single. Perform ahead of operation:
one. Verify if there is nitrogen in the nitrogen bottle. The nitrogen must be replaced in time. The output force of nitrogen is established to .4mpa.
two. Examine regardless of whether the vacuum pump is turned on typically.
3. Examine whether or not the circulation in the glove box is open. (Purification column-I or purification column-II must open up a single of them)
4. Check out the upper limit pressure in the setting should be +one, the reduced limit strain is
five. Check whether oxygen and dew position are standard (oxygen is under .1ppm, dew point is earlier mentioned -40)
six. The vacuum pump of the over-bin need to be in the typically open state
two. Procedure notes:
one. The vacuum pump must be retained on throughout system operation.
2. When the oxygen concentration in the tank exceeds 200PPM, the equipment upkeep personnel ought to be notified to function the program, or else the h2o and oxygen purification method will be destroyed.
3. Ahead of starting up the cycle, verify regardless of whether the cupboard is in issue or regenerating. As the above pointed out functions are in progress, it is absolutely forbidden to cycle.
four .Two purification columns are not able to be regenerated at the exact same time.
A. Just before regeneration, make certain 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.
