Kunzwisisa Hunhu hweElement

Usati wapinda mune chaiwo maprotocol e Kubata Liquid Argon, zvakakosha kuti unzwisise maitiro ayo uye njodzi dzinowanikwa dzavanopa. Argon (Ar) igasi risina ruvara, risinganhuhwi, risingaravi, uye risiri muchetura. Inoita 0.93% yemhepo yePasi. Kuti itakure nekuichengeta zvakanaka, inotonhodzwa kusvika kune tembiricha inonzi cryogenic—kunyanya, iri pasi pe-185.8°C (-302.4°F)—inoishandura kuita mvura.

Uku kudzikiswa kunoshamisa kwetembiricha uye kuwedzera kwereshiyo inozotevera kana yanyura ndizvo zvinonyanya kukonzera njodzi.

FAQs

Q1: Sei rudzi rwevhavha ine "yakawedzerwa bhoneti" inodiwa kune idzi cryogenic systems?

A: Mavharuvhu akajairwa anotadza kudziya tembiricha nekuti kutonhora kunoita kuti zvinhu zvemukati zvekuisa chisimbiso (kurongedza) zvideredze, zviite brittle, uye pakupedzisira kudonha kana kupwanyika. Ivhavhavha yebhoneti yakatambanudzwa inofambisa gland rinotakura kure kure kubva kune cryogenic fluid inoyerera nemumuviri wevharuvhu.

Q2: Kana iyo okisijeni inopera alarm inonzwika munzvimbo yekuchengetera, chii chiri kukurumidza kudiwa chiito?

A: Mhedziso yekutanga nhanho ndeyekubviswa kwenzvimbo nevashandi vese. Usaedze kuferefeta kwakabva alarm usina hunyanzvi hwekufema. Kana nzvimbo yacho yacheneswa, vanopindura zvechimbichimbi chete vakashongedzerwa neSelf-Contained Breathing Apparatus (SCBA) ndivo vanofanirwa kupinda munzvimbo iyi kuti vaone uye vaderedze kubuda kwacho, uku vachiwedzera kufefetedza kwenzvimbo kuparadzira mweya wakabviswa.

Q3: Ko vacuum-jacket piping (VJP) inosiyana sei neyakajairwa pombi insulation, uye nei ichidiwa?

A: Kuvharisa kwakajairwa, senge furo kana fiberglass, kunovimba nekuteya mweya kana gasi kunonotsa kutamisa kupisa. Pakupisa kwakanyanya kwe cryogenic, hunyoro hwemukati hunogona kudzika uye kuomesa mukati meyakajairwa insulation, zvichiparadza kushanda kwayo. VJP inoshandisa kuvakwa kwemadziro maviri ane vacuum yakakwirira pakati pepombi yemukati uye bhachi rekunze. Nekuti vacuum inenge isina mamorekuru ekuitisa kupisa, inoshanda zvakanyanya pakudzivirira kuvira uye kuchengetedza iyo yemvura panguva yekufambisa munzvimbo yeindasitiri.
