Precautions When Functioning The Glove Box
Vacuum glove box is widely used in industries with superior requirements for fuel purification. While the current glove box style and design is far more affordable and effortless to work. Even so, the construction inside the glove box is difficult, there are many significant components, and the procedure is somewhat incorrect, which might cause loss to your experimental final results. This write-up introduces you how to the right way use the vacuum glove box, and the safety measures when novices operate the vac glove box box.
A person. Perform ahead of operation:
one. Verify if there is nitrogen in the nitrogen bottle. The nitrogen ought to be replaced in time. The output force of nitrogen is established to .4mpa.
2. Look at whether the vacuum pump is turned on typically.
three. Verify regardless of whether the circulation in the glove box is open up. (Purification column-I or purification column-II must open up one of them)
four. Check out the higher limit pressure in the environment should really be +one, the reduce restrict force is
five. Check out no matter whether oxygen and dew point are ordinary (oxygen is beneath .1ppm, dew point is higher than -40)
six. The vacuum pump of the above-bin should really be in the generally open up point out
two. Procedure notes:
1. The vacuum pump ought to be retained on for the duration of system procedure.
2. When the oxygen concentration in the tank exceeds 200PPM, the tools servicing staff should really be notified to function the method, in any other case the drinking water and oxygen purification technique will be broken.
three. In advance of starting the cycle, check no matter whether the cabinet is in issue or regenerating. As the above mentioned functions are in development, it is totally forbidden to cycle.
four .Two purification columns can't be regenerated at the similar time.
A. Ahead of 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.
