Helium gas cylinder

Lus piav qhia luv luv:

Lub tog raj kheej roj yog lub nkoj siab rau kev khaws cia thiab ntim cov pa roj ntawm qhov siab tshaj atmospheric siab.

High-pressure gas cylinders kuj hu ua lub raj mis.Nyob rau hauv lub tog raj kheej cov ntaub ntawv khaws cia yuav nyob rau hauv lub xeev ntawm compressed gas, vapor tshaj kua, supercritical kua, los yog yaj nyob rau hauv ib tug substrate khoom, nyob ntawm seb lub cev yam ntxwv ntawm cov khoom.

Ib txwm gan roj kheej tsim yog elongated, sawv ntsug ntawm flattened hauv qab kawg, nrog lub valve thiab haum rau sab saum toj rau kev siv cov apparatus.

Daim ntawv thov

Helium yog siv dav hauv kev lag luam tub rog, kev tshawb fawb tshawb fawb, petrochemical, tub yees, kev kho mob, semiconductor, pipeline to detection, superconductivity trial, metal manufacturing, deep-sea diving, high-precision welding, optoelectronic products production, etc.

(1) Tsis tshua muaj kub cua txias: Siv qhov kub kub ntawm cov kua helium ntawm -268.9 ° C, kua helium tuaj yeem siv rau qhov txias txias txias.Ultra-tsawg kub cua txias tshuab muaj ntau yam kev siv nyob rau hauv superconducting technology thiab lwm yam teb.Cov khoom siv superconducting yuav tsum nyob rau qhov kub thiab txias (kwv yees li 100K) kom pom cov khoom siv superconducting.Feem ntau, tsuas yog cov kua helium tuaj yeem ua tau yooj yim xws li qhov kub thiab txias..Superconducting thev naus laus zis tau siv dav hauv maglev tsheb ciav hlau hauv kev lag luam tsheb thauj mus los thiab cov khoom siv MRI hauv kev kho mob.

(2) Balloon inflation: Vim tias qhov ntom ntawm helium tsawg dua li huab cua (qhov ntom ntawm huab cua yog 1.29kg / m3, qhov ntom ntawm helium yog 0.1786kg / m3), thiab cov khoom siv tshuaj lom neeg tsis tshua muaj zog, uas yog muaj kev nyab xeeb dua li hydrogen (hydrogen tuaj yeem nyob hauv huab cua flammable, tejzaum nws tawg), helium feem ntau yog siv los ua cov roj filling hauv spaceships lossis advertising balloons.

(3) Kev tshuaj xyuas thiab kev tshuaj xyuas: Cov hlau nplaum superconducting ntawm nuclear magnetic resonance analyzers feem ntau siv hauv kev ntsuas ntsuas yuav tsum tau txias los ntawm cov kua helium.Hauv kev tshuaj ntsuam roj chromatography, helium feem ntau yog siv los ua cov pa roj.Ua kom zoo dua ntawm qhov zoo permeability thiab tsis-flammable ntawm helium, helium Nws kuj yog siv rau hauv lub tshuab nqus tsev vacuum, xws li helium mass spectrometer leak detectors.

(4) Shielding gas: Siv cov khoom siv tsis muaj zog ntawm helium, helium feem ntau yog siv los ua cov roj thaiv thaiv kev vuam ntawm magnesium, zirconium, txhuas, titanium thiab lwm yam hlau.

(5) Lwm yam: Helium tuaj yeem siv los ua cov pa roj rau kev thauj cov kua hluav taws xob xws li kua hydrogen thiab cov pa oxygen ntawm cov foob pob hluav taws thiab lub dav hlau hauv cov khoom siv nqus tsev siab thiab cov tshuab hluav taws xob nuclear.Helium kuj tseem siv los ua tus neeg saib xyuas kev ua haujlwm atomic reactors, nyob rau hauv cov roj sib xyaw ua pa hauv kev txhim kho marine, ua cov roj filling rau cov ntsuas cua kub, thiab lwm yam.
