1, a vacuum atmosphere furnace is used for pumping gas in addition to specific sealed container so that the container certain vacuum degree of access to basic facilities, since the height of the development of modern science and technology, the vacuum pump to use across all fields of science and all kinds of enterprises and institutions for the metallurgical, chemical, light industry, petroleum, medical, pharmaceutical, printing, electronics, electric vacuum, semiconductor, food, atomic energy, textile and other research institutes, universities, industrial and mining production and for research and teaching.
2, the vacuum pump is in black metal, and more sophisticated, the entire pump work is connected with the oil, so it does not apply to high oxygen extraction, toxic, explosive black metal etching The vacuum oil from the chemical action of various gases and also not be used as compressor and pump use. If the pump gas ballast device can be exhausting amount of condensable gases.
3, vacuum pump used to obtain directly the degree of vacuum of 10-3 Torr vacuum operation, as well as with other vacuum device to obtain a vacuum of 10-3 torr vacuum operation with more than one.
4, the vacuum pump is generally in the temperature 50C ~ 400C and not more than 90% relative humidity environment. In addition to one of the basic equipment of pumping gas sealed container. It may be used alone, but also as a booster pump, diffusion pump, molecular pump before the pump to use. This series is widely used in metallurgy, machinery, electronics, chemicals, petroleum, pharmaceutical and other industries vacuum metallurgy, vacuum coating, vacuum heat treatment and vacuum drying process.
