How to maintain the vacuum drying oven during use? First, the laboratory equipment vacuum drying oven shell must be effectively grounded to ensure safe use. Second, the vacuum box studio prohibits the drying of items that are easy, explosive, and prone to corrosive gases. Third, the vacuum pump can not work for a long period of time. When the vacuum reaches the requirements of dry goods, first close the vacuum valve, then turn off the vacuum pump power supply. When the vacuum is less than the requirements of the dry items, then open the vacuum valve and vacuum pump power supply, continue to vacuum, so Extend the life of the vacuum pump. Fourth, the vacuum drying oven should be used under certain circumstances, generally the relative humidity ≤ 85% RH, no corrosive gas around, no strong vibration source and strong electromagnetic field. 5. If there is humid gas, it is better to add a filter between the vacuum box and the vacuum pump to prevent the humid gas from entering the vacuum pump and causing the vacuum pump to malfunction. 6. In the case of maintenance, the left side cover (except models 6090 and 6210) can be disassembled, otherwise it can not be disassembled to avoid damage to the electrical control system and fume hood. 7. After the laboratory equipment vacuum box is used for many times, there will be a phenomenon that vacuum cannot be taken. The door seal should be replaced in time or the extension of the door buckle on the box should be adjusted to solve the problem. 8. After drying, the weight of the article becomes lighter and the volume is small. The vacuum port should be added to the working chamber to add a barrier net to prevent the dry matter from inhaling and damage the vacuum pump (or solenoid valve). 9. If the laboratory equipment vacuum drying oven is not used for a long time, wipe the plating parts and apply neutral grease to prevent corrosion. Put on the plastic film dust cover and place it in the dry room to avoid damage to the electrical components. Affect. 10. If the rubber plug of the bleed valve is difficult to rotate, it can be lubricated with a proper amount of grease on the inside. 11. Laboratory equipment Vacuum drying ovens should always be kept clean. The door glass is wiped with a soft cotton cloth.
