Glove box is a closed system used to control and maintain specific environmental conditions, widely used in scientific research and industrial fields. However, during use, users may encounter various problems. Knowing the common problems and solutions of glove boxes can help locate and solve problems more quickly when using them.
1. Abnormal increase in gas consumption in glove box
Problem:
Abnormal increase in gas consumption in glove box.
Cause analysis:
There may be leaks in the pipeline from the working gas source to the glove box equipment.
High vacuum baffle valve may experience gas leakage.
The pressure pipe of the high vacuum baffle valve may also experience air leakage.
Solutions:
Check the pipeline from the working gas source to the glove box equipment to ensure there are no leaks.
Check the high vacuum baffle valve to ensure good sealing.
Check the pressure pipe of the high vacuum baffle valve to ensure there is no air leakage.
2. Fan tripping
Problem:
The fan suddenly trips.
Cause analysis:
Check the load condition to ensure it does not exceed the carrying capacity of the glove box equipment.
Excessive load causes circuit breaker tripping or frequency converter self-protection.
Solutions:
Check the solvent filtration system to ensure that the butterfly valve is correctly opened.
Check the load condition to ensure that it does not exceed the equipment's carrying capacity.
3. Abnormal noise generated by the fan
Problem:
The fan produces abnormal noise during operation.
Cause analysis:
Fan malfunction.
Solutions:
Please have a professional disassemble the fan for replacement.
4. Excessive water and oxygen content
Problem:
The water oxygen meter detects that the water and oxygen content exceed the standard.
Cause analysis:
Incorrect use of glove box equipment.
Poor sealing of the glove box.
Temperature affects water content.
The activated carbon is not baked thoroughly.
The regeneration effect is poor.
Solutions:
Ensure that the device is used correctly and avoid placing too many samples inside the glove box.
Check the airtightness of the glove box to ensure the correct use of large and small transition cabins and gloves.
Pay attention to the impact of temperature on water content, as excessive temperature can cause a slow decrease in water content.
Ensure thorough baking of activated carbon.
Check the regeneration effect and maintain the duration of vacuum pumping.
5. The glove box is continuously refilled with air
Problem:
The glove box keeps replenishing air.
Cause analysis:
There is a problem with the sealing of the glove box equipment.
The transition cabin door is not tightly closed.
The pedal is pressed by a foreign object.The pipeline solenoid valve of the purification system is blocked by impurities.
Solutions:
Perform pressure leak detection and check the sealing of glove box equipment.
Ensure that the transition cabin door is tightly closed.
Check and clean the pedals.
Clean or replace the pipeline solenoid valve of the purification system.
