Precautions when running the Nichwell glove boxPosted by Hassing Craven on March 13th, 2021 Vacuum glove box is commonly utilised in industries with large demands for fuel purification. Though the recent glove box style is more sensible and effortless to function. However, OLED/PLED/Solar Cell Glove box of the glove box is difficult, there are several crucial elements, and the operation is marginally improper, which may trigger reduction to your experimental benefits. This article introduces you how to correctly use the vacuum glove box, and the safety measures when novices work the glove box. A single. Function before operation: 1. Verify if there is nitrogen in the nitrogen bottle. The nitrogen must be replaced in time. The output pressure of nitrogen is established to .4mpa.
2. Check no matter whether the vacuum pump is turned on generally.
3. Verify no matter whether the circulation in the glove box is open up. (Purification column-I or purification column-II must open a single of them)
4. Check the upper limit pressure in the location need to be +1, the decrease limit pressure is
five. Check regardless of whether oxygen and dew point are normal (oxygen is beneath .1ppm, dew point is over -forty)
six. The vacuum pump of the in excess of-bin need to be in the generally open point out
two. Procedure notes:
one. The vacuum pump must be held on during technique operation.
2. When the oxygen concentration in the tank exceeds 200PPM, the equipment maintenance personnel need to be notified to run the method, otherwise the drinking water and oxygen purification system will be ruined.
three. Just before beginning the cycle, check whether or not the cabinet is in condition or regenerating. As custom glove box pointed out operations are in progress, it is definitely forbidden to cycle.
four .Two purification columns can't be regenerated at the very same time.
A. Prior to regeneration, make certain that the glove box has been cleaned with inert fuel (H2O <200ppm) to ensure sufficient supply of regeneration gas. Super Capacitor Glove Box 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.
