Oven is a kind of equipment used for material drying, curing, drying and other operations. It is commonly used in laboratories, medical, pharmaceutical, food, chemical and other fields. It can use different heat sources to heat-treat the material, and evaporate the moisture in the material, so as to achieve the purpose of drying.
The oven is usually composed of a heating system, a control system, a working chamber, and an inlet and outlet device. Heating systems usually use electric heating elements, gas stoves or steam heating to heat the air to a set temperature. The control system can accurately control parameters such as temperature, humidity, 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 problem
The temperature is unstable.
The appliance is heating unevenly.
The device makes noise or vibration.
The equipment leaks electricity or oil.
An error occurred in program operation.
Solution
Unstable temperature treatment: Check the working status of the temperature controller and the location of the sensor, and find out whether the controller or sensor is faulty or needs to be replaced. The problem can be solved by replacing or repairing related parts, or readjusting the temperature control parameters.
Treatment of uneven heating of equipment: check the working status and position of the heater, and check whether the position and heating time of the heater need to be readjusted so that the items in the equipment can be heated evenly.
Equipment noise or vibration treatment: If there is noise or vibration in the oven, you need to check whether the power supply voltage and ground wire of the equipment are normal, and find out whether the heater or fan is faulty or needs to be replaced. The problem can be solved by replacing or repairing related parts, or repositioning the equipment.
Equipment leakage or oil leakage treatment: check the internal circuit and lubrication system of the equipment, replace or repair the problematic parts in time, and ensure the normal operation of the equipment and the accuracy of the data.
Error handling in program operation: If an error occurs in program operation, it is necessary to reset the program or adjust the parameters in the controller.
The north and south tides remind you: the 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, 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
In the process of using the oven, you also need to pay attention to the following points:
Reasonably arrange the placement of samples to ensure that the samples can be heated and distributed evenly.
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.
Prior to testing, excellent preheating is performed to ensure that the equipment can reach the required temperature.
Choose reasonably according to actual needs
The heating power and precision of the oven can avoid inaccurate test data due to mismatch of equipment parameters. 5. In the process of using the equipment, record the heating changes and test data in time, and analyze and process them as needed.
In short, the 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.
