Why the vacuum drying box should be drawn first, then heating up

1. If the heating air is pulled out by the vacuum pump, the heat is inevitable if the heating air is pulled out by the vacuum pump. It will be taken to the vacuum pump, which will cause the vacuum pump temperature to rise too high, which may reduce the efficiency of the vacuum pump.

2. The gas after heating is directed to the vacuum pressure gauge, and the vacuum pressure gauge will generate temperature rise. If the temperature rise exceeds the use of
temperature range specified in the vacuum pressure gauge, it may cause the vacuum pressure gauge to generate a display value error.

The correct way of use should be vacuum before heating. After the rated temperature is reached, if the vacuum degree is discovered, add it appropriately. This is beneficial to the service life of extending equipment.

3. Put the workpiece into the vacuum box to draw vacuum to remove the gas composition that can be removed in the material material. If the workpiece is heated first, the gas will swell when the heat is heat. Due to the very good sealing of the vacuum box, the huge pressure generated by the expansion gas may cause the winding glass to explode. This is a potential danger. This is a danger that can be avoided according to the vacuum of the vacuum and then heating the heating.
