Ku bijyanye no gupima imiyoboro ishyushya amazi, nta kintu na kimwe cyaruta isuzuma rya helium mass spectrometer. Ubu buryo butuma umuntu yumva neza ko hari n'aho amazi asohoka ari mato cyane—kugeza kuri 5 × 10⁻¹³ mbar·L/s. Ariko ntabwo duhagarara aho. Ibi tubishyigikira dukoresheje isuzuma ryo kuzamuka k'umuvuduko, kugira ngo tubone neza uburyo icyuma gishyushya amazi cyangirika vuba uko igihe kigenda gihita. Muri ubwo buryo, dushobora kubona amazi asohoka no kugenzura ubuziranenge bwa sisitemu yose icyarimwe. Nyamara, igenzura ryoroshye akenshi riza mbere: shakisha gusa ibara ku ikoti ryo hanze. Buri mukoresha wese agomba kumenya ko agace k'ubukonje gashobora kuba ikimenyetso cy'uburinzi hakiri kare. Kandi kuri sisitemu zishyushye, kumenya amazi asohoka hakoreshejwe ikoranabuhanga birakenewe. Bizakira amazi asohoka ari kure ya metero 15.
Muri HL Cryogenics, dukoresha ubu buryo bwose, dukurikiza amahame ya ASME, CE, na ISO.Umuyoboro urinda ubushyuhe mu cyuma,Umuyoboro w'amazi ushyushye ukoresha amashanyarazi, cyangwa Mini Tank, buri gicuruzwa cyacu gisiga cyujuje ibisabwa bikomeye byo gufunga amazi, cyiteguye gukoreshwa aho ari ho hose ku isi.
Gutwara amazi ashyushye ntibibabarira amakosa. Tekereza kuri ibi: urimo gukoresha azote y'amazi kuri -196°C cyangwa LNG kuri -162°C unyuze mu muyoboro mu gihe umwuka wo hanze uri mu bushyuhe bw'icyumba. Icyuho cy'ubushyuhe ni kinini cyane—ndetse kirenze 250°C. Iyo umwobo w'imashini ufungutse mu gice cy'umwuka, umwuka urahita winjira. Mu buryo butunguranye, izo molekile z'umwuka zihinduka ibiraro bito by'ubushyuhe, bigasenya insulation. Ubushyuhe buhita bwiyongera, ibicuruzwa birabira vuba, kandi ibyo birahenda cyane cyane mu bice bya LNG mu majyepfo y'uburasirazuba bwa Aziya, aho igice kimwe gusa cyangiritse gishobora gupfusha ubusa amadorari ibihumbi by'amadolari buri munsi.
Ariko ingaruka zirenze amafaranga. Ishyirahamwe ry’i Burayi rishinzwe imyuka y’inganda ryanditse aho amazi yinjira mu bigega by’amazi ashyushye yateje ibiza. Tekereza ibi: hari ikintu cyacitse mu gikoresho cyo gusudira, amazi ashyushye yinjira mu mwanya w’amazi, maze ikoti ryo hanze rigakonja cyane ku buryo rihinduka ritoroshye. Iyo rimenetse burundu, ibice by’icyuma birarasa cyane. Urukurikirane rw’ibintu ruhora ari rumwe kandi ruhora ruteje akaga. Kubona ibi bibazo hakiri kare si ikintu cyiza gusa - ni ingenzi cyane ku mutekano.

Uburyo bwa 1 na 2: Igenzura ry'amaso no Gutahura urubura
Ntabwo ukeneye ibikoresho bigezweho kugira ngo umenye ibintu byoroheje kandi byizewe—ahubwo ukeneye abantu b'abahanga bazi icyo ugomba gushaka. Iyo umuntu agukeneye,Umuyoboro urinda ubushyuhe mu cyumacyangwa Mini Tank itakaza umwuka wayo urinda ubushyuhe, agace gakikije aho amazi aturuka gakonja vuba. Ubukonje buhagije ku buryo ubushuhe buva mu mwuka butuje, bugakonja, kandi bugatera ibibara by'urubura ku ikoti ryo hanze. Ibyo biragaragara cyane, cyane cyane iruhande rw'indi miyoboro ku bushyuhe bw'icyumba.
Buri gihe twereka abakiriya bacu uburyo bwo gukora ubu bushakashatsi buri gihe. Bibanda ku bintu bisanzwe bigaragara: gusudira, flanges, valves, n'ibihuzwa. Iyo umuntu abonye ubukonje cyangwa urubura inyuma y'ikoti—nta mazi asohoka—ni ikimenyetso gitangaje ako kanya. Ibyo bivuze ko hagarara, vuza induru, hanyuma utangire gusuzuma indwara. Ubu buryo bworoshye bwahagaritse ibintu byinshi mbere yuko bikomeza kwiyongera. Bikunze kugaragara cyane mu ruganda rw'inganda zo mu Burayi no mu nganda zikora ibikoresho bya semiconductor zo muri Aziya y'Iburasirazuba, aho kugira LN₂ ihoraho bidashoboka kuganirwaho.
Isuzuma ry’izamuka ry’umuvuduko rihoraho rikwereka niba umwuka uri mu cyogenic system uhagaze, ariko ntirikwereka neza aho amazi aturuka. Uburyo bworoshye: gufunga vacuum annulus, gufata vacuum gauge ipima neza, hanyuma urebe uko umuvuduko uhinduka uko igihe kigenda.
Dukoresheje Valves zikingira umwuka cyangwa Phase Separators, ubusanzwe dukora iki kizamini mu masaha 24, duhereye ku gitutu kiri munsi ya 1 × 10⁻³ Pa. Iyo igitutu kirenze umupaka washyizweho—nk'uko ISO 20486 cyangwa ASTM E1603 ibivuga—ibyo ni igihamya cy'uko hari amazi asohoka cyangwa imyuka myinshi iva mu kintu kiri imbere. Iki kizamini ni ingenzi—kugeza kuri 1 × 10⁻¹² Pa·m³/s—bityo rero kigomba guhangana n'ikibazo, ndetse no ku mishinga ya hydrogen yo mu Burasirazuba bwo Hagati ifite amahame yayo akomeye yo gusohora amazi.
Uburyo bwa 3: Isuzuma ry'uko Helium Mass Spectrometer ivamo amazi
Isuzuma ry’ibice bipima ikirere cya Helium ni ryo rigaragara nk'icyitegererezo cyiza cyo gupima no gupima ibice bisohoka mu buryo bukingira umwuka. Twishingikiriza kuri helium kubera impamvu yoroshye: ni yo myenge mito cyane idafite umwuka. Yinjira mu bice bito bidafite umwuka indi myuka idashobora kugeramo, nyamara ntiyigera igira icyo ikora ku bikoresho cyangwa ngo yonone amazi aturuka ku mwuka.
Dore uko inzira ikora. Dutangira gukuramo imashini ikoresha umwuka mu cyuma gifunga amashanyarazi, dukomeza gukoresha spectrometer y’umuvuduko mu cyuma gifunga amashanyarazi. Hanyuma dushyiramo helium ngufi, tuyitera ahantu hose hakekwa ko ari ho hakozwe isuku—imashini zisuka, ibyuma bifunga amashanyarazi, ingingo, n’aho bihurira ku gikoreshoUmuyoboro urinda ubushyuhe mu cyuma, Umuyoboro w'amazi uhindagurika, n'ibice by'amashanyarazi. Nubwo haba hari akantu gato cyane gasohoka, heliyumu iragasanga. Gazi inyura mu mwanya w'umwuka, spectrometer irayihuha, hanyuma igahita itanga ikimenyetso cy'uko hari ikibazo.
Gutemba kw'imbere bisaba ubundi buryo. Aho gutera heliyumu, dushyira heliyumu mu muyoboro w'imbere, tukayishyiramo umuvuduko. Iyo hari ikintu kivuye mu mwobo utagaragara kijya mu cyuma gipima amazi, icyuma gipima amazi gihita gifata ikimenyetso aho ngaho. Mu guhindura ubu buryo bwo "gutera" no gupima "gutera pressurization", nta nzira dusiga idafunze - imbere cyangwa hanze.
Buri gihe dukurikiza amahame akaze ya ASME Standard V, Ingingo ya 10, n'Inyongera ya IV na V. Ubu buryo budufasha kubona aho amazi amanuka kugeza kuri 5 × 10⁻¹³ mbar·L/s—uburyo buke bushobora guhuzwa n'ubundi.
Uburyo bwa 4: Gupima amazi asohoka hakoreshejwe ikoranabuhanga rya Ultrasonic
Gupima icyuma gipima ikirere kiba igikoresho cy'ingirakamaro cyo guherekeza isuzuma rya heliyumu mu gusuzuma byihuse sisitemu zishyushye cyane. Imyuka isohoka muri sisitemu ishyushye cyane isohora imyuka ihumanya ikirere bitewe n'amazi atemba cyane. Bityo, hakoreshejwe icyuma gipima ikirere gitwara abantu, abatekinisiye bashobora kubona amazi asohoka mu miyoboro ndetse no mu matsinda agoranye nka Vacuum Insulated Flexible Hose na cryogenic hoses batabangamiye imikorere ya sisitemu.
Ubu buryo bugira akamaro cyane cyane mu gihe cyo kumenya aho amazi ava mu byuma bisaba gukora buri gihe, nk'aho ajyanye n'ibikoresho bya LNG cyangwa inganda zikora gaze. Abatekinisiye bapima aho amazi ava mu byuma bashobora kumenya aho amazi ava mu byuma, bigatuma biba ikizamini cyihuse ariko kitagaragara cyane ugereranyije na helium mass spectrometry.
Ariko, kumenya aho amazi aturuka si iherezo ry'inkuru - gukumira aho amazi aturuka ni intego y'ubuhanga. HL Cryogenics'Umuyoboro urinda ubushyuhe mu cyuman'igishushanyo cya Mini Tanks birimo ingamba nyinshi zo kwirinda kwangirika kw'ibikoresho bivamo umwuka.
Ikintu cy'ingenzi cya sisitemu za HL Cryogenics zo gusohora umwuka ni ukoSisitemu yo gupompa ikoresha umwuka ushyushye, ibi bikaba byemeza ko ibikoresho bikomeza gukoreshwa mu buryo burambye mu gihe cyose cy'imikorere y'ibikoresho. Bitandukanye na sisitemu zisanzwe zikoresha amashanyarazi zihura n'ikibazo cyo kwangirika buhoro buhoro kw'ibikoresho byo mu nzu bitewe n'ibyuka byo mu nzu, sisitemu yacu ihora ikuraho imyuka isigaye mu cyuma gishyushya amazi, bigatuma ubushobozi bwo gukingira amashanyarazi buri munsi ya 1 × 10⁻³ Pa. Kubungabunga imikorere y'ibikoresho byongera igihe cyo kubaho.
Guhitamo ibikoresho neza ni ngombwa cyane. Dukoresha ibyuma bitarangirika bya austenitic (304L na 316L), bitanga icyizere cyo gukomera no kudashonga ku bushyuhe bukabije bwa -269°C. Ibyuma byacu byose bisudira bikozwe hakurikijwe ibisabwa na ASME Section IX kandi buri kimwe muri byo gisuzumwa hakoreshejwe isuzuma rya radiyo cyangwa irangi mbere yo gupima isuku. Ibicuruzwa byacu byemejwe na ASME, CE na ISO, bitanga ubushobozi bwo gukora ibicuruzwa hakurikijwe ibipimo by'igihugu icyo ari cyo cyose - byaba ari PED ku masoko y'i Burayi, ASME B31.3 ku miyoboro ya LNG yo muri Amerika, cyangwa GB/T 18442 ku byuka by'inganda byo mu Bushinwa.
Ihuriro ry'ubwumvikane
Fata umushinga uherutse gukorwa mu kigo cyo kuvugurura LNG mu majyepfo y'uburasirazuba bwa Aziya. Hari metero zirenga 200 zaUmuyoboro urinda ubushyuhe mu cyuma, assemblies nyinshi za Vacuum Insulated Valve, n'izindi nyinshiUmuyoboro w'amazi ushyushye ukoresha amashanyaraziHagombaga gushyirwaho imiyoboro yo kwimura amazi kuva ku bwato kugera ku nkombe. Intambwe ya mbere y'uburyo bwacu bwo kumenya aho amazi aturuka ni ugupima helium mass spectrometer y'ibisundiro byose n'ingingo mu iduka ryacu, mbere yuko ibikoresho bigezwa aho byakorewe.
Intambwe ya kabiri yari ikizamini cy’inyongera cyakorewe aho hantu hakoreshejwe ikizamini cya helium mass spectrometer n’ikizamini cya ultrasound. Mu gihe cya nyuma, abatekinisiye babonye ikimenyetso kidasanzwe cy’ijwi giturutse ku muyoboro wa flange, cyari cyarasuzumwe mbere. Ikizamini cya helium cyagaragaje ko hari amazi ari munsi ya 1 × 10⁻⁸ mbar·L/s, byangiza imikorere ya vacuum insulation mu mezi make yakurikiyeho y’akazi. Nyuma yo gusana flange seal no gusubiramo ibizamini, gufunga kw’amazi byagenzuwe neza. Ubu, terminal ikora buri gihe mu myaka itatu, nta kwangirika kw’amazi.
Rero, kumenya aho amazi aturuka mu miyoboro ishyushya amazi mu buryo bwa "vacuum proof" si ikoranabuhanga rimwe gusa, ahubwo ni uburyo bugoye bwo gukora imashini buhuza igenzura ry’amaso, isuzuma ry’umuvuduko, isuzuma rya helium mass spectrometer hamwe no gusuzuma hakoreshejwe ikoranabuhanga.
Ubu buryo bwose bwo gupima buri mu buryo bwa QA muri HL Cryogenics, bityo buriUmuyoboro urinda ubushyuhe mu cyuma, Umuyoboro w'amazi ushyushye ukoresha amashanyarazi, Valve ikingira umwuka,Itandukaniro ry'icyiciro cya "Vacuum Insulated Phase"r, na Mini Tank twatanze byujuje ibisabwa mpuzamahanga by’ubuziranenge. Kuva ku ruganda rwa LNG mu majyepfo y’uburasirazuba bwa Aziya kugeza ku ruganda rwa semiconductor muri Aziya y’Iburasirazuba, kuva ku ruganda rw’inganda rukora imyuka ikomoka ku gazi mu Burayi kugeza ku ruganda rwa hydrogen mu Burasirazuba bwo Hagati—umushinga uwo ari wo wose ufite, injeniyeri zacu zizaba zifite ubumenyi n’ubuhanga (ASME, CE, na ISO)—kugira ngo ziguhe sisitemu zirinda amazi kandi zikora neza cyane.
Vugana na HL Cryogenics ubu ngubu utubwire icyo umushinga wawe ukeneye mu bijyanye no kumenya aho amazi aturuka. Itsinda ryacu ry’abahanga rizategura uburyo bukenewe bwo gupima aho amazi aturuka ku mazi aturuka gusa kuri sisitemu yawe yo gupima aho amazi aturuka!
