Some considerations for vacuum drying ovens:
1. The vacuum box housing must be effectively grounded to ensure safe use.
2. When the vacuum box does not need continuous pumping, the vacuum valve should be closed first, then the vacuum pump power supply should be turned off, otherwise the vacuum pump oil should be poured into the box.
3, take out the torn items to be treated, such as the treatment of flammable items, must be cooled to below the ignition point before the air can be placed, so as not to cause oxidation reaction caused by burning.
4. There is no explosion-proof device in the vacuum box, and it is not allowed to put the explosive materials into the dry.
5. It is best to cross the filter between the vacuum box and the vacuum pump to prevent the wet body from entering the vacuum pump.
6. If it is not necessary, please do not open the side door at will to avoid damage to the electrical system.
7. This equipment should be equipped with a special air switch.
8. The electrical insulation is intact, and the equipment casing must have reliable protection grounding or protection to zero.
9. The vacuum pump should be replaced with vacuum pump oil frequently.
10. When taking out the processed items, if the processed items are flammable, the air must be cooled to below the ignition point before the air can be placed to avoid the oxidation reaction causing the combustion.
11. This equipment has no explosion-proof device and should not be placed in explosive materials for drying.
12. When using the electric vacuum drying oven, special personnel must be taken care of to ensure the normal operation of the equipment.
13. When the electric vacuum drying oven is not used for a long time, the items in the working room should be taken out and wiped clean to keep the equipment dry.
