Vacuum drying ovens are widely used in many fields, including biochemistry, chemical pharmaceuticals, medical care, agricultural research, and environmental protection. It can not only be used for drying and baking powders, but also for disinfecting and sterilizing various glass containers.
Detailed explanation of the operating steps of the vacuum drying oven
The vacuum drying oven is a commonly used laboratory equipment used to dry samples in a vacuum environment. Its operation method is relatively simple, but some key steps need to be paid attention to to ensure that the drying task is completed safely and effectively. The following is a detailed explanation of the operation steps of the vacuum drying oven:
First, make sure that the vacuum drying oven has been properly installed and is in a stable working state. Next, place the sample to be dried in the drying oven, paying attention to the sample placement regulations. Then, close the drying oven door and start the vacuum pump to start extracting air from the oven to achieve the desired vacuum level. During the drying process, it is necessary to pay close attention to the working status of the drying oven, including changes in the vacuum level and the drying of the sample. Once the predetermined drying time or effect is reached, the vacuum pump and the heating function of the drying oven should be turned off immediately, and the sample should be allowed to cool naturally in a vacuum environment. Finally, open the drying oven door, take out the dried sample, and close the drying oven.
During operation, be sure to follow relevant safety regulations and precautions to ensure the safety of personnel and equipment. At the same time, regularly maintain the vacuum drying oven to extend its service life and improve work efficiency.
Instructions for using the vacuum drying oven
When operating a vacuum drying oven, be sure to follow the key precautions below to ensure safe and effective operation of the equipment:
Ensure that the equipment is placed stably and away from flammable and explosive items to prevent the risk of fire or explosion.
Before use, check that the power cord is intact and that the power socket is well grounded to ensure safe operation.
Strictly follow the operating instructions to avoid equipment failure or accidents due to misoperation.
During the drying process, pay close attention to the temperature and vacuum changes in the drying oven, and adjust them in time to ensure the best drying effect.
After drying, be sure to follow the correct shutdown and vacuum release steps to protect the equipment and extend its service life.
By following these precautions, you will be able to use the vacuum drying oven more safely and efficiently, bringing more convenience to scientific research and production.
1. To ensure safe use, the shell of the vacuum box must be effectively grounded.
2. When the vacuum box is used discontinuously for vacuuming, the vacuum valve should be closed first, and then the power supply of the vacuum pump should be disconnected to prevent the vacuum pump oil from flowing back into the box.
3. When taking out the processed items, especially flammable items, it is necessary to ensure that the temperature has dropped below the ignition point before air can be introduced to avoid combustion caused by oxidation reaction.
4. Since the vacuum box is not equipped with explosion-proof devices, it is strictly forbidden to use it for drying explosive items.
5. To prevent wet objects from entering the vacuum pump, it is recommended to install a filter between the vacuum box and the vacuum pump.
6. Non-professionals should not remove the side door at will to prevent damage to the electrical system.
7. The equipment should be equipped with a special air switch to ensure the safety of the electrical system.
8. Before use, check whether the electrical insulation is intact, and the equipment shell must be reliably grounded or zeroed.
9. Replace the vacuum pump oil regularly to keep the vacuum pump in the best working condition.
10. When handling flammable items, wait until the temperature drops below the ignition point before letting in air to prevent oxidation reactions.
11. When using an electric vacuum drying oven, it should be monitored by a dedicated person to ensure stable operation of the equipment.
12. When the electric vacuum drying oven is not used for a long time, the workroom should be emptied and wiped clean to keep the equipment dry.
13. If the electric vacuum drying oven has any abnormal situation, it should be checked and repaired immediately. If the cause of the failure cannot be determined, please contact the technical department of the purchasing company for help.
Maintenance and care of vacuum drying oven
As a key equipment in laboratories and industrial production, the stability and safety of vacuum drying ovens are crucial to ensure the smooth progress of experiments and production processes. In order to ensure that the vacuum drying oven can operate stably for a long time and maintain its good performance, correct maintenance and care are particularly important. The following are some maintenance suggestions for vacuum drying ovens:
Check the electrical system regularly: ensure good electrical insulation and reliable grounding or zeroing of the equipment casing to ensure safe operation.
Professional operation: non-professionals should not dismantle the side door at will to prevent damage to the electrical system.
Reasonable use of vacuum pump: when not in continuous use, the vacuum valve should be closed first, and then the power supply of the vacuum pump should be disconnected to prevent the vacuum pump oil from pouring back into the box.
Pay attention to the safety of dry items: especially for flammable items, it is necessary to ensure that the temperature has dropped below the ignition point before air can be introduced to avoid combustion caused by oxidation reaction. At the same time, since the vacuum box is not equipped with explosion-proof devices, it is strictly forbidden to use it for drying explosive items.
Prevent wet objects from entering the vacuum pump: it is recommended to install a filter between the vacuum box and the vacuum pump to protect the vacuum pump from damage by wet objects.
Regularly replace the vacuum pump oil: this can ensure that the vacuum pump always maintains the best working condition, thereby extending the service life of the equipment.
Special person monitoring: when using an electric vacuum drying oven, it should be monitored by a special person to ensure stable operation of the equipment and timely detection and handling of any abnormal conditions.
Maintenance when not in use for a long time: When the electric vacuum drying oven is not in use for a long time, the working room should be emptied and wiped clean to keep the equipment dry to prevent moisture and rust.
Handling of abnormal situations: If the electric vacuum drying oven has abnormal conditions, it should be checked and repaired immediately. If the cause of the failure cannot be determined, please contact the technical department of the purchasing company for help.
In summary, following these maintenance recommendations can ensure that your vacuum drying oven is always in optimal working condition, thus providing stable and reliable protection for your experiments and production processes.
