The vacuum Drying Oven is a device that uses a low-pressure environment in a vacuum state to perform operations such as material drying, curing, and drying. In the vacuum state, the boiling point of water molecules is lowered and can be evaporated at a lower temperature, thereby reducing the thermal damage on the surface of the material and ensuring the drying effect and the quality of the item.
The vacuum Drying Oven is usually composed of a vacuum system, a heating system, a control system, a working chamber, and an inlet and outlet device. The vacuum system can reduce the internal pressure of the Drying Oven to a lower vacuum state to reduce the heat conduction of the air to the material; the heating system usually uses electric heating elements, gas stoves or steam heating to heat the air to the set temperature. The control system can accurately control parameters such as temperature, vacuum degree, and time to meet the processing needs of different materials. The design and construction of the working room and the feeding and discharging device will also vary according to different usage scenarios and material requirements.
Common Problems and Their Solutions
1. Vacuum degree is unstable
Solution: Check the working status of the Vacuum Pump and the vacuum degree controller, and find out whether the pump or controller is faulty or needs to be replaced. The problem can be solved by replacing or repairing related parts, or readjusting the control parameters of the vacuum degree.
2. Uneven heating of the equipment
Solution: Check the working status and position of the heater, and check whether it is necessary to readjust the position and heating time of the heater so that the items in the device can be heated evenly.
3. Noise or vibration occurs on the device
Solution: If there is noise or vibration in the vacuum drying box, you need to check whether the power supply voltage and ground wire of the equipment are normal, and find out whether the heater or Vacuum Pump is faulty or needs to be replaced. The problem can be solved by replacing or repairing related parts, or repositioning the equipment.
4. The equipment leaks air or water.
Solution: Check the sealing performance and air and water leakage inside the equipment, and replace or repair the problematic parts in time to ensure the normal operation of the equipment and the accuracy of the data.
5. An error occurred in the program operation.
Solution: If there is an error in the program operation, it is necessary to reset the program or adjust the parameters in the controller.
North and South Chao reminds you: the vacuum Drying Oven needs to be calibrated and maintained regularly. At the same time, it is necessary to regularly clean the interior of the equipment, check the performance and condition of heaters, Vacuum Pumps, controllers, sensors and other equipment, and replace or repair problematic parts in time. In addition, it is recommended to carry out maintenance according to the operation manual of the equipment and the maintenance instructions provided by the manufacturer to ensure the long-term stable operation of the equipment.
Precautions for use
In the process of using a vacuum Drying Oven, you also need to pay attention to the following points:
Arrange the position of the sample reasonably to ensure that the sample can be evenly heated and distributed in vacuum.
Do not accumulate too much sundries or samples inside the equipment, so as not to affect the operation of the equipment and the accuracy of the data.
According to actual needs, reasonably select the vacuum degree range, heater power and precision of the vacuum Drying Oven to avoid inaccurate test data due to mismatching equipment parameters. 4. Before the test, preheating should be carried out to ensure that the equipment can reach the required temperature and vacuum conditions.
During the use of the equipment, the heating and vacuum degree changes and test data are recorded in time, and analyzed and processed as needed.
In short, the vacuum Drying Oven is a commonly used laboratory equipment, but it is necessary to pay attention to the use and maintenance of the equipment during use to ensure the stability of the equipment and the accuracy of the test data.
