Silinda ya gasi ya Helium

Kufotokozera Kwachidule:

Silinda ya gasi ndi chotengera choponderezedwa kuti chisungidwe komanso kusungitsa mpweya womwe uli pamwamba pa mlengalenga.

Ma cylinders othamanga kwambiri amatchedwanso mabotolo.Mkati mwa silinda zomwe zasungidwa zimatha kukhala mu mpweya wothinikizidwa, nthunzi pamadzimadzi, madzimadzi apamwamba kwambiri, kapena kusungunuka mu gawo lapansi, kutengera mawonekedwe amkati.

Mapangidwe a silinda a gasi amatalikitsidwa, kuyima chowongoka kumapeto kwapansi, ndi valavu ndikuyika pamwamba kuti ilumikizane ndi zida zolandirira.

Kugwiritsa ntchito

Helium amagwiritsidwa ntchito kwambiri m'makampani ankhondo, kafukufuku wasayansi, petrochemical, refrigeration, chithandizo chamankhwala, semiconductor, kuzindikira kutayikira kwa payipi, kuyesa kwapamwamba, kupanga zitsulo, kumiza m'madzi akuya, kuwotcherera mwatsatanetsatane, kupanga optoelectronic, etc.

(1) Kuziziritsa kwa kutentha pang'ono: Pogwiritsa ntchito malo otentha otsika a helium yamadzimadzi ya -268.9 °C, helium yamadzimadzi ingagwiritsidwe ntchito pozizira kwambiri.Ukadaulo wozizira kwambiri wotentha kwambiri uli ndi ntchito zingapo muukadaulo wa superconducting ndi magawo ena.Zipangizo zopangira ma superconducting ziyenera kukhala zotsika kwambiri (pafupifupi 100K) kuti ziwonetse katundu wapamwamba kwambiri.Nthawi zambiri, helium yamadzimadzi yokha imatha kukwaniritsa kutentha kwambiri..Ukadaulo wa Superconducting umagwiritsidwa ntchito kwambiri m'masitima apamtunda a maglev m'makampani oyendetsa komanso zida za MRI pazachipatala.

(2) Kukwera kwa baluni: Popeza kuchuluka kwa helium ndikocheperako kuposa mpweya (kuchuluka kwa mpweya ndi 1.29kg/m3, kuchulukitsitsa kwa helium ndi 0.1786kg/m3), ndipo mankhwala ake sagwira ntchito, yotetezeka kuposa haidrojeni (hydrogen imatha kuyaka mumlengalenga, mwina kuphulika), helium imagwiritsidwa ntchito ngati mpweya wodzazitsa m'zombo kapena ma baluni otsatsa.

(3) Kuyang'ana ndi kusanthula: Maginito a superconducting a nyukiliya magnetic resonance analyzer omwe amagwiritsidwa ntchito posanthula zida amayenera kuzizidwa ndi helium yamadzi.Pakuwunika kwa chromatography ya gasi, helium imagwiritsidwa ntchito ngati mpweya wonyamulira.Kutengera mwayi wokwanira bwino komanso kusayaka kwa helium, heliamu imagwiritsidwanso ntchito pozindikira kutayikira kwa vacuum, monga zowunikira za helium mass spectrometer leak.

(4) Kuteteza mpweya: Pogwiritsa ntchito mankhwala osagwira ntchito a helium, helium imagwiritsidwa ntchito ngati mpweya wotchinga powotcherera magnesium, zirconium, aluminium, titaniyamu ndi zitsulo zina.

(5) Mbali zina: Helium angagwiritsidwe ntchito ngati gasi pressurized kunyamula propellants madzi monga madzi wa hydrogen ndi mpweya wamadzimadzi pa roketi ndi mlengalenga mu zipangizo vacuum mkulu ndi reactors nyukiliya.Helium imagwiritsidwanso ntchito ngati choyeretsa chopangira ma atomiki, mu mpweya wosakanikirana wopumira m'munda wa chitukuko cha m'madzi, ngati mpweya wodzaza ma thermometers a gasi, ndi zina zambiri.
