1. The enclosure must be effectively grounded to ensure safe use.
2. The vacuum dryer should be used in an environment where the relative humidity is less than or equal to 85% RH, and there is no corrosive gas around, no strong vibration source and strong electromagnetic field.
3. There is no explosion-proof and anti-corrosion treatment in the working room of the vacuum dryer, and items that are easy to be exposed, explosive, and prone to corrosive gas shall not be placed for drying.
4. The vacuum pump cannot work for a long time. Therefore, when the vacuum degree reaches the requirements of the dry goods, the vacuum valve should be closed first, and then the power of the vacuum pump should be turned off. When the vacuum degree is less than the requirements of the dry goods, the vacuum valve and the power of the vacuum pump should be turned on, and the vacuum should be continued. This extends the life of the vacuum pump.
5. If the dry items are wet, it is best to add a filter between the vacuum box and the vacuum pump to prevent the wet gas from entering the vacuum pump and cause the vacuum pump to malfunction.
6. If the dry items are changed to be light in weight and small in size (small particles) after drying, a barrier net should be added to the vacuum port in the work room to prevent the vacuum pump (or solenoid valve) from being damaged by the inhalation of dry matter.
7. After the vacuum dryer is used for many times, the phenomenon that the vacuum cannot be drawn will occur. At this time, the door seal should be replaced or the distance of the door buckle on the box should be adjusted to solve it. When the drying temperature of the vacuum box is higher than 200 ℃, slow air leakage will occur. At this time, remove the back cover of the box and use an Allen wrench to loosen the heater base, replace the sealing ring or tighten the heater base to solve the problem.
8. Regularly check explosion-proof devices, especially vacuum dryers that handle dangerous goods.
9. The vacuum dryer should be kept clean frequently. The door glass should not be wiped with reactive chemical solutions, but should be wiped with a soft cotton cloth.
10. If the vacuum dryer is not used for a long time, wipe the exposed electroplating parts and apply neutral grease to prevent corrosion, and put on a plastic film dust cover and place it in a dry room to prevent electrical components from being damaged by moisture. Affect.
