Safeguards When Functioning The Glove Box
Vacuum glove box is greatly utilised in industries with higher demands for fuel purification. Whilst the recent glove box design and innovative technologies glovebox style is extra sensible and effortless to work. Nevertheless, the structure inside the glove box is challenging, there are several crucial components, and the operation is a little incorrect, which may trigger loss to your experimental results. This report introduces you how to correctly use the vacuum glove box, and the safeguards when novices operate the glove box.
One particular. Operate ahead of procedure:
one. Check out if there is nitrogen in the nitrogen bottle. The nitrogen need to be changed in time. The output force of nitrogen is established to .4mpa.
2. Test whether or not the vacuum pump is turned on usually.
3. Check out no matter whether the circulation in the glove box is open. (Purification column-I or purification column-II should open up a person of them)
4. Check the upper limit tension in the environment should be +1, the lessen restrict strain is
five. Check out no matter whether oxygen and dew stage are normal (oxygen is under .1ppm, dew issue is higher than -40)
6. The vacuum pump of the in excess of-bin must be in the commonly open up point out
two. Operation notes:
1. The vacuum pump should really be held on through method procedure.
two. When the oxygen focus in the tank exceeds 200PPM, the machines upkeep personnel should really be notified to work the system, otherwise the drinking water and oxygen purification system will be damaged.
three. Just before starting the cycle, examine no matter whether the cabinet is in situation or regenerating. As the above stated functions are in progress, it is unquestionably forbidden to cycle.
four .Two purification columns are unable to be regenerated at the similar time.
A. Before regeneration, be certain that the glove box has been cleaned with inert fuel (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.
