Safety Measures When Operating The Glove Box
Vacuum glove box is broadly used in industries with significant prerequisites for fuel purification. Even though the present-day glove box style is additional realistic and easy to operate. Even so, the structure within the glove box is intricate, there are lots of crucial elements, and the operation is a little improper, which could bring about loss to your experimental outcomes. This posting introduces you how to accurately use the vacuum glove box, and the safeguards when novices work the glove box.
One. Get the job done ahead of operation:
1. Look at if there is nitrogen in the nitrogen bottle. The nitrogen really should be changed in time. The output force of nitrogen is set to .4mpa.
two. Test no matter if the vacuum pump is turned on generally.
three. Check no matter whether the circulation in the glove box is open. (Purification column-I or purification column-II ought to open 1 of them)
4. Examine the upper limit strain in the placing really should be +one, the lower restrict strain is
five. Verify whether or not oxygen and innovative technologies glovebox dew place are ordinary (oxygen is below .1ppm, dew point is higher than -40)
six. The vacuum pump of the more than-bin need to be in the ordinarily open state
two. Operation notes:
1. The vacuum pump need to be held on all through technique procedure.
2. When the oxygen focus in the tank exceeds 200PPM, the products upkeep personnel should be notified to run the program, or else the h2o and oxygen purification program will be ruined.
three. Prior to starting off the cycle, look at whether or not the cabinet is in issue or regenerating. As the above described operations are in progress, it is absolutely forbidden to cycle.
four .Two purification columns are unable to be regenerated at the exact same time.
A. Just before regeneration, 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.
