Safety measures when operating the Nichwell glove boxPosted by Nichwell Glovebox on February 17th, 2021 Vacuum glove box is broadly utilised in industries with higher needs for fuel purification. Though glove box price is more affordable and simple to run. Nonetheless, the composition inside of the glove box is challenging, there are several crucial elements, and the operation is marginally improper, which may cause loss to your experimental results. This report introduces you how to properly use the vacuum glove box, and the precautions when novices work the glove box. 1. Operate before operation: 1. Check if there is nitrogen in the nitrogen bottle. The nitrogen must be changed in time. The output strain of nitrogen is set to .4mpa. two. Check out whether the vacuum pump is turned on normally. 3. Examine no matter whether the circulation in the glove box is open up. (Purification column-I or purification column-II should open up a single of them) four. Check out the higher limit force in the placing ought to be +one, the decrease limit stress is 5. Check out whether or not oxygen and dew point are standard (oxygen is under .1ppm, dew level is earlier mentioned -40)
6. The vacuum pump of the above-bin ought to be in the usually open point out
two. Operation notes:
one. The vacuum pump should be held on during technique operation.
2. When the oxygen concentration in the tank exceeds 200PPM, the tools servicing personnel must be notified to operate the system, or else the water and oxygen purification technique will be broken.
three. Before starting the cycle, check regardless of whether the cupboard is in condition or regenerating. As the earlier mentioned mentioned functions are in progress, it is absolutely forbidden to cycle.
four .Two purification columns can not be regenerated at the same time.
A. Before regeneration, guarantee that the glove box has been cleaned with inert gasoline (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.
