Kvarca cauruļu maksimālā darba temperatūra vakuuma lietojumos

Kvarca caurules are a prevalent material known for their exceptional thermal stability and high-temperature resistance. Widely used in industrial vacuum equipment, their maximum operating temperature is a focal point of interest.

The maximum temperature at which a kvarca caurule can be used in a vacuum is influenced by several factors, including the material of the quartz tube, its wall thickness, the external environment temperature, and the vacuum level.

Firstly, the material of the kvarca caurule plays a decisive role in its high-temperature resistance. Made from high-purity silicon dioxide, quartz tubes exhibit excellent heat and corrosion resistance. Generally, the maximum operating temperature of a quartz tube can reach up to about 1200 degrees Celsius.

Kvarca caurules sieniņu biezums ietekmē arī tās izturību pret augstu temperatūru. Plānās sienas kvarca caurules ir pakļautas termiskā stresa lūzumiem augstās temperatūrās, savukārt biezākas sienas var labāk izturēt termisko spriegumu augstas temperatūras vidē. Tāpēc atbilstošais sienas biezums jāizvēlas, pamatojoties uz konkrēto darba temperatūru un vidi.

The external environment temperature is another factor affecting the maximum use temperature of kvarca caurules. If the ambient temperature is too high, it can adversely affect the quartz tube’s temperature resistance. Hence, when using quartz tubes, it’s crucial to arrange cooling devices properly to ensure they operate within a suitable temperature range.

Vakuuma līmenis ir būtisks faktors, kas ietekmē maksimālo darba temperatūru. Augsta vakuuma apstākļos gāzes siltumvadītspēja ir slikta, palēninot temperatūras paaugstināšanos kvarca caurulēs, ļaujot tām izturēt augstāku temperatūru. Turpretim zema vakuuma apstākļos gāzes siltumvadītspēja ir labāka, kas izraisa ātrāku temperatūras paaugstināšanos un zemāku maksimālās temperatūras toleranci.

In summary, the maximum operating temperature of kvarca caurules in vacuum applications is influenced by multiple factors. When selecting and using quartz tubes, it’s essential to consider material, wall thickness, external environmental temperature, and vacuum level to ensure stable operation within the appropriate temperature range. Furthermore, to enhance the high-temperature resistance of kvarca caurules, measures like ceramic casing and cooling devices can be employed to reduce surface temperature and minimize thermal stress impact.
