●Ingingo ya 1 yo Guhitamo: Guhagarara neza kwa sisitemu y'ubushyuhe mu gihe runaka
Ikibazo gikomeye ku batanga serivisi ni icyoroshye: ese icyuho gikomeza kubaho nyuma yo gutangira akazi, cyangwa ntigikomeza?
Twishingikiriza kuriSisitemu yo gupompa ikoresha umwuka ushyushyekugira ngo ifu ikomeze gukomera mu buryo bunini bwo gushyuha. Sisitemu zihamye ziguma aho ngaho, ariko pompe ikomeza gukora—ikurikirana imyuka mito, ikemura imyuka isohoka, kandi ikemura ibibazo byose biterwa n’ubushyuhe.
Muri ubu buryo, mu by'ukuri dukomeza gushyira igipimo cy'ubushyuhe munsi ya 10⁻³ mbar aho ari ingenzi cyane. Ubona ubushyuhe buke buvamo amazi, ndetse n'imyaka myinshi nyuma y'umurongo. Byongeye kandi, icyizere cy'ibikorwa bya LNG bihoraho n'imiyoboro minini ya gazi kiriyongera cyane.
Ku mishinga ya EPC, ibi bivuze ko ibikorwa byo kubungabunga bigabanuka. Uko igihe kigenda gihita, ibikorwa byose bigenda neza kandi bigatwara amafaranga make.
●Ingingo ya 2 yo Guhitamo Ingingo z'ingenzi: Guhuza Ibice by'Ikoranabuhanga n'Urwego
Mu guhuzaSisitemu yo gupompa ikoresha umwuka ushyushye, Valve ikingira umwuka, naIgitandukanya Icyiciro, tuguha uburyo bwo gutwara heliyumu y'amazi neza kandi bugabanye ibiciro.Ikigega gitonaImiyoboro yoroshyereka dukore akazi kagendanwa n'ako mu buryo buhamye.
Sisitemu za Cryogenic zikora neza nk'umuyoboro uhuriweho, ntabwo ari ibice byinshi bikora ibyabyo.
TurahuzaUmuyoboro urinda ubushyuhe mu cyuma, Umuyoboro w'amazi uhindagurika, naValve ikingira umwukamu buryo bumwe buhuriweho butuma igitutu kidahindagurika kandi bugacunga impinduka mu byiciro.
Umuyoboro woroshye ugira uruhare runini iyo ibikoresho bigenda cyangwa binyeganyega kandi ubushyuhe bugahinduka — birakomeye bihagije kugira ngo bikomeze koroha mugihe bifashe umwuka wabyo, ndetse na nyuma y'ibihe byinshi by'ubukonje bukabije.
Mu gihe cy'igenzura rikomeye, icyuma gikingira umwuka gishyushyaIgitandukanya IcyiciroGutandukanya amazi n'umwuka. Muri ubwo buryo, ibikoresho byo hasi nka LNG vaporizers cyangwa semiconductor cooling systems birinda urujya n'uruza rw'amazi mu byiciro bibiri kandi bigakomeza kuba bihamye.
●Ingingo ya 3 yo Guhitamo: Igenzura ry'Imyitwarire y'Icyiciro cy'Ubwubatsi
Kudahuzagurika kw'ibyiciro ni ikibazo gikomeye mu buhanga bwo gukwirakwiza amakuru, cyane cyane iyo bigeze ku bikorwa bya EPC.
Aho niho iwacuIgitandukanya cy'imashini ikoresha amashanyaraziInjiramo. Iki gikoresho gikomeza ko amazi atangwa neza binyuze mu kubuza umwuka kwinjira mu mvange—ndetse n'igihe igitutu cy'amazi cyinjiramo kizamuka hagati ya 0.3 na 1.6 MPa, bitewe n'uburyo sisitemu iteye.
Uzabona impamvu ibi ari ingenzi mu bice nko mu gukora ibikoresho bya semiconductor (MBE, gushushanya, gukonjesha wafer), ibyuma bihindura gazi bya LNG, no gukoresha azote y'amazi mu gutunganya ibiribwa n'ibinyobwa.
Iyo ukoresheje intera ihamye, ubona urujya n'uruza rw'ibintu rushobora gusobanurwa neza kandi ibyo bigira ingaruka ku musaruro w'ibikorwa no kubahiriza amategeko y'umutekano. Ni ukugira ngo ibintu bikomeze kugenda neza kandi mu mutekano.
●Ingingo ya 4 yo Guhitamo Iby'ingenzi: Gukurikiza Amahame Ngenderwaho Mpuzamahanga y'Ubwubatsi
Kugira ngo ufashwe nk'umucuruzi utanga serivisi z'ubutabazi bw'umwimerere, ugomba kugaragaza ko wujuje amategeko mpuzamahanga.
Muri HL Cryogenics, ntabwo dushyira ibintu mu gaciro. Twubaka byose dukurikije amahame ya ASME ku bikoresho bikoreshwa mu gushyushya, dukurikiza amategeko ya EN agenga ihuzwa rya EPC mu Burayi, kandi tugakurikiza sisitemu za ISO ku bwiza no gusudira. Ibyo bivuze ko ibikoresho byacu bikorana neza n'abakora EPC mu Burayi, mu majyepfo y'uburasirazuba bwa Aziya, no mu Burasirazuba bwo Hagati—ahantu aho kwemeza ubwubatsi bigomba kuzuza ibisabwa bikomeye kandi byambukiranya imipaka.
Dore ibyabaye ku mushinga w’ibikorwa remezo bya LNG mu majyepfo y’uburasirazuba bwa Aziya. Bari bakeneye azote y’amazi ihoraho kugira ngo bakoreshwe mbere yo gukonjesha. Ariko rwiyemezamirimo wabo wa EPC yahuye n’ibibazo bikomeye: umuvuduko w’amashanyarazi n’ibinure byinshi, byose bitewe nuko ubushyuhe bw’imiyoboro yabo ishaje, yari ivanzemo ibice, butayicagaguye.
Twaje duhindura sisitemu kugira ngo tugire ikintu gikomeye: imiterere yuzuye hamweUmuyoboro urinda ubushyuhe mu cyuma, Umuyoboro w'amazi uhindagurika, naIgitandukanya Icyiciro—byose bishyigikiwe naSisitemu yo gupompa ikoresha umwuka ushyushyekugira ngo ifu ikomeze kuba nziza uko igihe kigenda gihita.
Ibisubizo byari bisobanutse neza. Ubushyuhe bwagabanutseho hafi 85%. Umuvuduko wagumye uhamye, muri ± 0.05 MPa. Ubuvuzi? Gabanura inyuma cyane, uhereye ku icyiciro cya mbere.
Mu by’ukuri, ibi bigaragaza ko ubuhanga bwo ku rwego rwa sisitemu ari bwo butuma EPC igera ku ntsinzi—atari ugusimbuza ibice bimwe na bimwe gusa.
●Ibibazo Bikunze Kubazwa
Kuva mu 1992, HL Cryogenics yiganje mu gushushanya no gukora imiyoboro ya cryogenic ishyushye cyane hamwe n'ibikoresho bijyana nayo, byagenewe guhaza ibyifuzo bitandukanye by'abakiriya. Dufite ibyemezo bya ASME, CE, na ISO 9001, kandi twatanze ibicuruzwa na serivisi ku bigo byinshi mpuzamahanga bizwi cyane. Ikipe yacu ni inyangamugayo, ifite inshingano, kandi yiyemeje gukora neza muri buri mushinga dukora.
