Precautions for using a vacuum dryer
Nov 12, 2018

1. The housing must be effectively grounded to ensure safe use.

2. Vacuum dryer should be used in the relative humidity ≤85%rh, around non-corrosive gas, no strong vibration source and strong electromagnetic field exists in the environment.

3. Vacuum Dryer Studio Without explosion-proof, anti-corrosion and other treatment, should not put Igian, explosive, easy to produce corrosive gas items for drying.

4. Vacuum pump can not work for a long time, so when the vacuum to meet the requirements of dry goods, should first close the vacuum valve, and then turn off the pump power supply, until the vacuum is less than the requirements of dry items, and then open the vacuum valve and vacuum pump power supply, continue to vacuum, which can extend the service life of the vacuum pump.

5. Dry items such as moisture, it is best to add a filter between the vacuum box and the vacuum pump to prevent moist gas from entering the vacuum pump, resulting in vacuum pump failure.

6. Dry items, such as after drying changes to light weight, small size (small granular), should be in the working room vacuum mouth plus barrier mesh, in order to prevent the drying of the suction and damage to the vacuum pump (or solenoid valve). 

7. Vacuum dryer After many uses, will produce can not vacuum phenomenon, at this time should replace the door seal or adjust the door buckle on the box to extend the distance to solve. When the vacuum box drying temperature is higher than 200 ℃, will produce a slow leakage phenomenon (except 6050, 6050B, 6051, 6053), at this time to disassemble the box behind the cover plate with the inner hexagonal wrench loosening the heater base, changing the sealing ring or tightening the heater base to solve. 

8. If the release valve rubber plug is difficult to rotate, can be coated with a moderate amount of grease lubrication.

9. In addition to maintenance, can not disassemble the left box cover (except type 6090 and 6210) to avoid damage to the electrical control system. 

10. Vacuum dryers should be kept clean on a regular basis. Box door glass should not be wiped with a reactive chemical solution, the application of soft cotton wipe. 

11. If the vacuum dryer is not used for a long time, will be exposed to the electroplating parts after wiping a neutral grease, to prevent corrosion, and put on the plastic film dust cover, placed in a dry room, so as to avoid moisture damage to electrical components, affecting the use.
