Safety Measures When Functioning The Glove Box
Vacuum glove box is commonly employed in industries with large demands for gasoline purification. While the current glove box style and design is additional acceptable and effortless to function. Having said that, the framework inside of the glove box is intricate, there are numerous essential pieces, and the operation is a bit inappropriate, which may well bring about decline to your experimental benefits. This write-up introduces you how to accurately use the vacuum glove box, and the safety measures when novices function the glove box.
One particular. Operate before operation:
one. Check out if there is nitrogen in the nitrogen bottle. The nitrogen must be replaced in time. The output stress of nitrogen is established to .4mpa.
two. Verify no matter if the vacuum pump is turned on commonly.
3. Check out whether the circulation in the glove box is open. (Purification column-I or purification column-II really should open one of them)
4. Test the higher restrict strain in the location really should be +one, the lower limit strain is
five. Check out no matter if oxygen and dew point are regular (oxygen is under .1ppm, dew level is over -40)
six. The vacuum pump of the more than-bin ought to be in the normally open up point out
two. Operation notes:
one. The vacuum pump should be kept on throughout process operation.
two. When the oxygen concentration in the tank exceeds 200PPM, the machines servicing personnel should be notified to run the method, if not the water and oxygen purification program will be damaged.
three. Right before commencing the cycle, test regardless of whether the cabinet is in affliction or regenerating. As the previously mentioned pointed out functions are in development, it is unquestionably forbidden to cycle.
four .Two purification columns simply cannot be regenerated at the exact time.
A. Prior to regeneration, be 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.
