As i-semiconductorkanye nobuchwepheshe be-microelectronic buthuthukela ekusebenzeni okuphezulu nokuhlanganiswa okuphezulu, izidingo eziphakeme zibekwe ekuhlanzekeni kwamagesi akhethekile kagesi. Ubuchwepheshe bepayipi legesi obuhlanzekile buyingxenye ebalulekile yesistimu yokuhlinzeka ngegesi ehlanzekile. Ubuchwepheshe obubalulekile bokuletha amagesi ahlanzekile ahlangabezana nezidingo ezindaweni zokusebenzisa igesi kuyilapho kugcinwa ikhwalithi efanelekile.
Ubuchwepheshe bamapayipi obuhlanzekile buhlanganisa ukuklama okulungile kwesistimu, ukukhethwa kokufakwa kwamapayipi kanye nezinto ezisizayo, ukwakhiwa nokufakwa nokuhlola.
01Umqondo ojwayelekile wamapayipi okudlulisa igesi
Wonke amagesi ahlanzekile kakhulu futhi ahlanzeke kakhulu kudingeka athuthelwe endaweni yokugcina igesi ngamapayipi. Ukuze kuhlangatshezwane nezidingo zekhwalithi yenqubo yegesi, lapho inkomba yokuthekelisa igesi iqinisekile, kudingekile kakhulu ukunaka ukukhethwa kwezinto ezibonakalayo kanye nekhwalithi yokwakha yohlelo lwamapayipi. Ngaphezu kokunemba kokukhiqizwa kwegesi noma imishini yokuhlanza, kuthinteka kakhulu izici eziningi zesistimu yamapayipi. Ngakho-ke, ukukhethwa kwamapayipi kudinga ukuhambisana nemigomo yemboni yokuhlanza efanele futhi kuphawule izinto zamapayipi emidwebeni.
02Ukubaluleka kwamapayipi ahlanzeke kakhulu ekuthuthweni kwegesi
Ukubaluleka kwamapayipi ahlanzekile kakhulu ekuthuthweni kwegesi ehlanzekile kakhulu Ngesikhathi senqubo yokuncibilikisa insimbi engagqwali, ithani ngalinye lingamunca cishe u-200g wegesi. Ngemva kokuba insimbi engagqwali isicutshunguliwe, akukhona nje kuphela ukuthi ukungcola okuhlukahlukene kunamathele endaweni yayo, kodwa futhi nenani elithile legesi limuncwa ku-lattice yayo yensimbi. Uma kukhona ukugeleza komoya okudlula epayipini, ingxenye yegesi emuncwa insimbi izophinde ingene ekugelezeni komoya futhi ingcolise igesi emsulwa.
Lapho ukugeleza komoya epayipini kungaqhubeki, ipayipi lakha i-pressure adsorption kugesi elidlulayo. Lapho ukugeleza komoya kuyeka ukudlula, igesi ekhangiswa ipayipi yenza ukuhlaziywa kokunciphisa ukucindezela, futhi igesi ehlaziywe iphinde ingene egesi elihlanzekile epayipi njengokungcola.
Ngesikhathi esifanayo, umjikelezo we-adsorption nokuhlaziya uzobangela insimbi endaweni yangaphakathi yepayipi ukukhiqiza inani elithile lempushana. Le zinhlayiya zothuli lwensimbi futhi zingcolisa igesi ehlanzekile epayipini. Lesi sici sepayipi sibaluleke kakhulu. Ukuze kuqinisekiswe ukuhlanzeka kwegesi ethuthwayo, akudingeki nje kuphela ukuthi indawo yangaphakathi yepayipi inobushelelezi obuphezulu kakhulu, kodwa futhi kufanele ibe nokumelana nokugqoka okuphezulu.
Uma igesi inamandla okugqwala, amapayipi ensimbi engagqwali angagqwali kufanele asetshenziselwe ukufaka amapayipi. Uma kungenjalo, izindawo zokugqwala zizovela endaweni engaphakathi yepayipi ngenxa yokugqwala. Ezimweni ezimbi kakhulu, izingcezu ezinkulu zensimbi zizoxebuka noma zibhoboze, ngaleyo ndlela zingcolise igesi ehlanzekile ethuthwayo.
03Impahla yepayipi
Ukukhethwa kwezinto ezibonakalayo zepayipi kudinga ukukhethwa ngokuvumelana nezidingo zokusetshenziswa. Izinga lepayipi ngokuvamile likalwa ngokusho kokuqina kwendawo yangaphakathi yepayipi. Uma buphansi ubuhwaba, mancane amathuba okuthi athwale izinhlayiya. Ngokuvamile ihlukaniswe yaba izinhlobo ezintathu:
Eyodwa nguIpayipi le-EP grade 316L, eye yapholishwa ngogesi (Electro-Polish). Iyakwazi ukumelana nokugqwala futhi inobuhhewu obuphansi. I-Rmax (isilinganiso esiphezulu sokuphakama kuya kobude besigodi) sicishe sibe ngu-0.3μm noma ngaphansi. Inokucaba okuphezulu kakhulu futhi akulula ukwenza ama-micro-eddy currents. Susa izinhlayiya ezingcolile. Igesi yokusabela esetshenziswa kule nqubo kufanele ifakwe ngamapayipi kuleli zinga.
Omunye u-aBA grade 316Lipayipi, elashwe yi-Bright Anneal futhi elivame ukusetshenziselwa amagesi axhumene ne-chip kodwa angahlanganyeli ekuphenduleni kwenqubo, njenge-GN2 ne-CDA. Elinye ipayipi le-AP (Annealing & Picking), elingaphathwanga ngokukhethekile futhi elivame ukusetshenziselwa amasethi akabili amapayipi angaphandle angasetshenziswa njengezintambo zokuphakela igesi.
04 Ukwakhiwa kwamapayipi
Ukucutshungulwa komlomo wepayipi kungenye yamaphuzu abalulekile alobu buchwepheshe bokwakha. Ukusikwa kwepayipi kanye nokwakhiwa kwangaphambili kwenziwa endaweni ehlanzekile, futhi ngesikhathi esifanayo, kuqinisekiswa ukuthi awekho amamaki ayingozi noma umonakalo ebusweni bepayipi ngaphambi kokusika. Amalungiselelo okugezwa kwe-nitrogen epayipini kufanele enziwe ngaphambi kokuvula ipayipi. Ngokomthetho, i-welding isetshenziselwa ukuxhuma amapayipi okuhambisa igesi okuhlanzeka okuphezulu nokuhlanzeka okuphezulu ngokugeleza okukhulu, kodwa ukushisela okuqondile akuvunyelwe. Amajoyinti e-casing kufanele asetshenziswe, futhi impahla yepayipi esetshenzisiwe iyadingeka ukuba kungabikho ukuguqulwa kwesakhiwo ngesikhathi sokushisela. Uma izinto ezinokuqukethwe kwekhabhoni ephezulu kakhulu zishiselwe, ukungena komoya kwengxenye yokushisela kuzobangela ukuthi igesi ngaphakathi nangaphandle kwepayipi ingene komunye nomunye, ibhubhise ukuhlanzeka, ukoma nokuhlanzeka kwegesi elidlulisayo, okuzoholela emiphumeleni emibi kakhulu. futhi kuthinte ikhwalithi yokukhiqiza.
Kafushane, kumapayipi egesi ahlanzeke kakhulu kanye namapayipi adlulisa igesi akhethekile, kufanele kusetshenziswe ipayipi lensimbi engagqwali elashwe ngokukhethekile, elenza uhlelo lwamapayipi ahlanzeke kakhulu (okuhlanganisa amapayipi, izifakelo zamapayipi, amavalvu, i-VMB, i-VMP) luthathe indawo umsebenzi obalulekile ekusabalaliseni igesi ehlanzekile.
