Vacuum drying oven is widely used in biochemistry, chemical and pharmaceutical, medical and health, agricultural scientific research, environmental protection and other research applications, for powder drying, baking, and disinfection and sterilization of various glass containers. It is especially suitable for fast and efficient drying treatment of dry heat sensitive, easily decomposed, easily oxidized substances and complex composition items.
The vacuum drying oven does not require the operator to perform meticulous maintenance work, but basic maintenance is essential, which can make the equipment service life longer, and will also play a certain role in improving the production quality of the product.
1. After the production is completed, if the vacuum drying oven is not used for a long time, care should be taken to clean all parts, especially the oven door sealing strip, to prevent aging. Close the door of the vacuum drying oven tightly. Don't tighten the locking device of the door too tightly to prevent deformation, and cut off the power and water source.
2. When the cabinet is not used for a long time, the cabinet should be cleaned regularly. Please do not use liquids with strong acid or alkali strength for cleaning. Use clean water to clean it. After cleaning, you should pay attention to wipe the water dry.
3. For the rotary vane vacuum pump, the vacuum pump oil should be replaced regularly, once or twice a month. If it is not used for a long time, the vacuum pump oil must be drained after the last use, and new vacuum pump oil should be injected before the next use.
4. For the water ring vacuum pump, the circulating water must be replaced once a day. If it is not used for a long time, the water in the vacuum pump must be drained after the last use. When the temperature is below minus in winter, the vacuum pump must be used every day. If the water supply is exhausted, pay attention to whether the vacuum pump is rusted to death before using it next time. If it is rusted to death, remove the back cover of the vacuum pump motor and screw the motor shaft with a tool.
5. If the equipment fails during normal use, it should be reported to the manufacturer immediately and should not be disassembled by itself to avoid serious damage.
6. Common parts need to be replaced after expiration. If the vacuum gauge is damaged, a new vacuum gauge needs to be replaced immediately. The sealing strip is aging due to age and should be purchased from the manufacturer. After a long time, each valve will cause the PTFE sealing ring in the valve. If the vacuum cannot be pumped to a reasonable value due to wear and tear, a new air valve should be replaced immediately.
