Safety Measures When Functioning The Etelux Glove Box
Vacuum glove box is greatly used in industries with higher prerequisites for gas purification. Though the latest glove box layout is far more fair and easy to run. Nevertheless, the construction inside of the glove box is intricate, there are many crucial areas, and the operation is a bit incorrect, which could cause decline to your experimental outcomes. This report introduces you how to effectively use the vacuum glove box, and the precautions when novices function the glove box.
A single. Perform before operation:
1. Check 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.
2. Test irrespective of whether the vacuum pump is turned on normally.
3. Verify no matter whether the circulation in the Glove Box Application box is open up. (Purification column-I or purification column-II ought to open up a person of them)
four. Check the higher restrict tension in the location really should be +one, the reduced restrict tension is
five. Check whether or not oxygen and dew issue are standard (oxygen is below .1ppm, dew point is previously mentioned -40)
six. The vacuum pump of the about-bin should really be in the ordinarily open up condition
two. Procedure notes:
one. The vacuum pump really should be kept on for the duration of system procedure.
two. When the oxygen focus in the tank exceeds 200PPM, the gear routine maintenance personnel need to be notified to work the program, in any other case the h2o and oxygen purification technique will be broken.
three. In advance of setting up the cycle, verify whether or not the cupboard is in issue or regenerating. As the previously mentioned talked about operations are in progress, it is completely forbidden to cycle.
4 .Two purification columns can't be regenerated at the very same time.
A. In advance of 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.
