Safety measures when functioning the glove box

oleh Gidget Kater (2020-05-25)

Vacuum glove box is widely used in industries with large demands for gas purification. Whilst the existing glove box layout is extra acceptable and easy to work. However, the framework inside of the glove box is complex, there are numerous vital parts, and the procedure is slightly poor, which may possibly result in decline to your experimental success. This short article introduces you how to correctly use the vacuum glove box, and the safeguards when novices run the glove box.

One. Do the job ahead of operation:

one. Check out if there is nitrogen in the nitrogen bottle. The nitrogen really should be replaced in time. The output tension of nitrogen is established to .4mpa.

two. Check out no matter if the vacuum pump is turned on generally.

3. Look at whether or not the circulation in the glove box is open up. (Purification column-I or purification column-II should really open 1 of them)

four. Look at the higher limit pressure in the setting should really be +one, the decreased limit strain is

5. Examine whether or not oxygen and dew stage are normal (oxygen is below .1ppm, dew place is earlier mentioned -40)

6. The vacuum pump of the over-bin should really be in the typically open condition

two. Operation notes:

one. The vacuum pump should be saved on all through system operation.

two. When the oxygen focus in the tank exceeds 200PPM, the machines servicing staff must be notified to work the process, normally the drinking water and oxygen purification process will be broken.

3. Prior to setting up the cycle, look at no matter if the cupboard is in issue or regenerating. As the previously mentioned pointed out operations are in development, it is definitely forbidden to cycle.

four .Two purification columns are not able to be regenerated at the similar time.

A. Right before regeneration, guarantee 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.
