Vacuum glove box is extensively made use of in industries with significant prerequisites for fuel purification. Whilst the current glove box design and style is far more affordable and effortless to function. However, the structure within the glove box is challenging, there are numerous critical parts, and the procedure is a little improper, which may well result in loss to your experimental results. This short article introduces you how to effectively use the vacuum glove box, and the safeguards when novices run the glove box.

1. Get the job done in advance of operation:

one. Verify if there is nitrogen in the nitrogen bottle. The nitrogen must be replaced in time. The output tension of nitrogen is set to .4mpa.

2. Test no matter if the vacuum pump is turned on typically.

three. Look at whether the circulation in the glove box is open up. (Purification column-I or purification column-II should really open just one of them)

four. Verify the upper limit pressure in the location need to be +one, the reduce limit pressure is

five. Test no matter if oxygen and dew place are standard (oxygen is down below .1ppm, dew issue is previously mentioned -40)

6. The vacuum pump of the over-bin need to be in the ordinarily open condition

two. Operation notes:

one. The vacuum pump need to be saved on through method procedure.

two. When the oxygen concentration in the tank exceeds 200PPM, the gear servicing staff should be notified to run the procedure, usually the water and oxygen purification procedure will be weakened.

three. Right before starting the cycle, examine whether the cupboard is in affliction or regenerating. As the above stated functions are in progress, it is totally forbidden to cycle.

four .Two purification columns can't be regenerated at the exact same time.

A. Ahead of regeneration, be certain that the glove box has been cleaned with inert glove box 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.
