Precautions for novice operating glove box
One. Work before operation:
1. Check if there is nitrogen in the nitrogen cylinder, replace the nitrogen in time, and set the output pressure of the nitrogen to 0.5mpa.
2. Check whether the vacuum pump is turned on normally.
3. Check whether the loop in the glove box is open. (Open one of the purification column-I or purification column-II)
4. Check that the upper limit pressure in the setting should be +1, and the lower limit pressure should be 0
5. Check whether the oxygen and dew point are normal (the oxygen is below 0.1ppm, and the dew point is above -40)
6. The vacuum pump of the transition chamber should be in the normally open state
Two. Operation of large and small cabins: (large warehouses generally enlarge parts, small warehouses generally put tools)
Okura
Put the items outside the glove box inside
1. Close the big warehouse door in the glove box tightly
2. Open the door outside the warehouse
3. Put in items
4. Close the door outside Okura tightly
5. Evacuate to -1.0 (press the green button at the bottom right corner of the warehouse to evacuate, and press it without releasing it.)
6. Release the nitrogen gas to 0 (press the orange button at the bottom right corner of the warehouse to release the nitrogen gas, and press it without releasing it.)
7. Open the large warehouse door in the glove box and take out the items
Take the items in the glove box out
1. Close the two doors of Okura tightly
2. Vacuum to -1.0 (press the green button in the lower-left corner of the warehouse to vacuum, press it and not release.)
3. Release the nitrogen to 0 (Releasing Nitrogen by pressing the button in the lower-left of the large antechamber, press down and hold on)
4. Open the door inside the warehouse and put items in the warehouse
5. Close the door inside the warehouse
6. Open the door outside the warehouse to take out the items.
7. Close the door outside the warehouse tightly.
Kokura
Put the items outside the glove box inside
1. Close the small warehouse door in the glove box tightly.
2. Open the door outside the small warehouse.
3. Put in items.
4. Close the door outside the small warehouse tightly.
5. Clean so that the inside of the small compartment is at -0.1 (turn the handle outside the small compartment to clean).
6. Exhaust to make the small compartment at 0 (turn the handle outside the small compartment to exhaust).
7. Open the small compartment door in the glove box and take out the items.
Take the items in the glove box out
1. Close the two doors of Kokura tightly.
2. Clean so that the inside of the small compartment is at -0.1 (turn the handle outside the small compartment to clean).
3. Exhaust air to make the small compartment at 0 (turn the handle outside the small compartment to exhaust).
4. Open the door inside the small warehouse and put items in the small warehouse.
5. Close the door inside the small warehouse tightly.
6. Open the door outside the small warehouse to take out the items.
7. Close the door outside the small warehouse tightly.
Three. Operation note:
1. The vacuum pump should be kept on while the system is working.
2. When the oxygen concentration in the box exceeds 200PPM, the equipment maintenance personnel should be notified to perform system operation, otherwise, the water and oxygen purification system will be damaged.
3. Check before starting the cycle to see if the cabinet is in condition or regeneration. If the operation mentioned above is in progress, it is absolutely forbidden to loop.
4. Two purification columns cannot be regenerated at the same time.
A. Before regeneration, ensure that the glove box has been cleaned by inert gas (H2O<200ppm) to ensure sufficient regeneration gas supply. The regeneration gas pressure is 0.06-0.08mpa.
B. Before starting the regeneration, please confirm that the corresponding purification column cycle is closed.
C. The regeneration process takes 24 hours. Once executed, the regeneration gas cannot be disconnected. Pay attention to the amount of regeneration gas 3-6 hours after the start of regeneration. Adjust the pressure of the regeneration gas appropriately to ensure that the regeneration gas is adequately supplied during these 3 hours. The regeneration origin can be closed after the 6th hour.
D. The vacuum pump cannot be turned off during the regeneration process. Avoid touching 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, otherwise the equipment will be damaged.
5. Care should be taken to protect the working gloves from damage during operation.
Maintenance:
1. Primary maintenance:
1.1 Cleaning. Once a day
2. Secondary maintenance:
2.1 Fasten the screws and nuts that are easy to come loose. Once a month
2.2 Fasten the electrical components. Once every 3 months
2.3 Correction temperature. Once every 3 months
