Some Matters Needing Attention During the Use of a Vacuum Drying Oven
The following points should be paid attention to when using a vacuum drying oven
1. The vacuum drying oven shell must be effectively grounded to ensure the use of insurance.
2. It is used under the conditions of absolute humidity ≤85% RH, no corrosive gas around, no violent shock source, and a strong electromagnetic field.
3.It is to be dried in the mission room without explosion-proof, anti-corrosion, and other solutions, not easy to put, flammable, easy to produce corrosive gas items for drying.
4. The vacuum pump can’t work for a long time, so when the vacuum degree meets the requirements of dry goods, the vacuum valve should be closed first, then close the vacuum pump power. When the vacuum degree is less than the requirements of dry goods, then open the vacuum valve and the vacuum pump power, continue to pump vacuum, so as to extend the service life of the vacuum pump.
5. If the dry goods are wet, a filter should be added between the empty chamber and the vacuum pump to prevent the damp gas from entering the vacuum pump and causing the vacuum pump failure.
6. If the rubber plug of the air release valve is difficult to rotate, it can be internally coated with an appropriate amount of grease for lubrication.
7. In addition to maintenance, do not open the left oven cover to avoid damaging the electrical control system.
8. Empty containers should always be kept clean. Do not wipe the door glass with a reactive chemical solution, use a soft cotton cloth to wipe.
9. If the empty oven is not used for a long time, wipe the exposed electroplating parts clean and coat them with neutral grease to prevent corrosion and cover them with plastic film dust cover. Place them in a dry room to avoid damp damage to electrical components and affect their use.
10. If the item becomes lighter and smaller after drying, a barrier net should be added in the vacuum mouth, in order to prevent dry inhalation and protect the vacuum pump.
11. After repeated use, if the vacuum is unworkable, change the door cover or change the door buckle space on the oven.
12. If it is hard to wind the cylinder paperweight plug, it can be coated with excessive grease to make it smooth.
13. Except for repair, please do not open the inside cover to protect the electric material control system.
14. Always keep it clean. Do not wipe the door glass with the reflective chemical filtrate. Use a solid cotton cloth instead.
Storage of the vacuum drying oven
If the vacuum drying oven is stored for a long period of time, it should be coated in neutral oil or grease plating to prevent corrosion, and put on the molecular compound plastic film dust cover to prevent moisture, lest electrical components moisture infiltration and affect the use. Vacuum drying oven should always maintain clean, door glass should be made of soft cotton yarn loose cloth wipe, effectively avoid using a chemical solvent wipe, so as to avoid chemical reactions and wipe the glass.
If there is an abnormal phenomenon, it should be detected early. If operators can not correctly judge the failure, please contact HAWACH technical departments.
