Vacuum oven usage tips

　　 Drying ovens and ovens are used to determine the suitability of non-heat-dissipating electrical and electronic products (including components, equipment, and other products) subjected to temperature changes without adverse effects in storage or use under high-temperature environmental conditions. Roasting and drying can be performed at temperatures ranging from 5 to 300°C or even higher.

Ovens are becoming more and more widely used in our daily life. There are many models of drying ovens and ovens, and the basic structure is similar . However, due to the negligence of the relevant personnel and their lack of understanding, there have been a series of problems in the use process. The following Kunshan Haida instrument engineers discussed the problems with the vacuum drying oven frequently.

What are the proper techniques for using the oven and oven ?

　　 1. If the drying box is operated by heating and then vacuuming, the heated air is pumped by the vacuum pump. Heat will inevitably be carried to the vacuum pump. This will cause the vacuum pump to rise too high, which may cause the vacuum pump to decrease in efficiency. .

　　 2. The correct method of use should be vacuumed and heated again. After the rated temperature is reached, if the degree of vacuum is found to have decreased, add it again. This is advantageous for extending the useful life of the equipment.

　　 3 , the general electric vacuum drying oven is used to heat the wall of the vacuum chamber first, and then the radiation heating method of the wall facing the workpiece. In this way, the temperature sensor's temperature sensor can be placed on the vacuum outside wall. The sensor can accept convection, conduction, and radiant heat simultaneously.

4. Generally, it is normal that the temperature reading of the instrument at 200°C is within 30°C of the reading of the glass rod thermometer. If the temperature sensor of the temperature-control instrument is arranged in a vacuum chamber, the difference between the temperature value of the glass rod thermometer and the temperature reading of the instrument can be appropriately reduced, but it cannot be eliminated, and the sealing reliability of the vacuum chamber increases a possibly unreliable link. .
