1. The shell of the vacuum dryer must be grounded effectively to ensure safe use.
2. The vacuum dryer should be used in an environment where the relative humidity is H, there is no corrosive vacuum dryer gas around, and there is no strong vibration source and strong electromagnetic field.
3. There is no explosion-proof, anti-corrosion and other treatments in the vacuum dryer working room, and no items that are flammable, explosive, or prone to corrosive gas can be put into the double-cone rotary vacuum dryer.
4. The vacuum dryer cannot work for a long time. Therefore, when the vacuum degree reaches the requirements of the double cone rotary vacuum dryer, the vacuum valve should be closed first, and then the vacuum pump power supply. When the vacuum degree is less than the double cone rotary vacuum dryer requirements, Turn on the vacuum valve and the power supply of the vacuum pump to continue vacuuming, which can prolong the service life of the vacuum pump.
5. If the items of the double cone rotary vacuum dryer are wet, it is better to add a filter between the vacuum box and the vacuum pump to prevent wet gas from entering the vacuum pump and causing vacuum pump failure.
6. Light weight and small size (in the form of small particles), a barrier net should be added to the vacuum port in the working chamber to prevent the double cone rotary vacuum dryer from being sucked in and damaging the vacuum pump (or solenoid valve).
7. After the vacuum dryer has been used for many times, it will not be able to draw a vacuum. At this time, the door seal should be replaced or the door buckle on the box body should be adjusted to solve the problem. When the temperature of the vacuum box double-cone rotary vacuum dryer is higher than 200℃, slow air leakage will occur (except 6050, 6050B, 6051, 6053). At this time, disassemble the back cover of the double-cone rotary vacuum dryer. Loosen the heater base with an Allen wrench, change the sealing ring or tighten the heater base to solve the problem.
8. If the rubber plug of the air release valve is difficult to rotate, it can be lubricated with a proper amount of grease inside. (Like petroleum jelly)
9. Except for maintenance, the left side box cover (except 6090 and 6210 models) cannot be removed to avoid damage to the electrical control system.
10. The vacuum dryer should always be kept clean. Do not wipe the glass of the door with a reactive chemical solution, and should be wiped with a soft cotton cloth.
11. If the vacuum dryer is not used for a long time, wipe the exposed electroplated parts and apply neutral grease to prevent corrosion, and put on a plastic film dust cover, and place it in the double cone rotary vacuum dryer room to avoid corrosion. The electrical components are damaged by damp, which affects the use.
