Chitsanzo cha kufalikira kwa madzi: choyamba konzani matanki ofunikira, kenako matanki ena osungira. Tsimikizani mafunde onse ndi masiku awiri owunikira ntchito pambuyo poyika pansi pa njira yodzaza/kutulutsa madzi.
Kupereka ndi kuphunzitsa: maphunziro a ogwiritsa ntchito ndi kukonza ndi ma SOP omveka bwino owunikira ndi kuthetsa mavuto
Perekani maphunziro okonzedwa bwino a wogwiritsa ntchito ogwirizana ndi ma SOP. Pitirizani kufufuza tsiku ndi tsiku kuti mudziwe kuchuluka kwa nayitrogeni wamadzimadzi, yankho la alamu, ndi kutanthauzira koyambira kwa ma echo. Phunzitsani ogwiritsira ntchito kuzindikira njira zodziwika bwino zolephera monga kutayika kwa ma echo, kuwerenga kosakhazikika panthawi ya slosh, ndi zolakwika za mawaya.
Perekani maphunziro osamalira omwe amayang'ana kwambiri pa chitetezo cha cryogenic, kuyang'anira probe, njira zowunikira, ndi njira zina zosinthira. Phatikizanipo masewero olimbitsa thupi ochotsa ndi kukhazikitsanso probe kapena ma sensor clamp osalowerera pamene mukusunga umphumphu wa vacuum.
Perekani zikalata zomveka bwino za SOP. Ma SOP ayenera kulemba njira zotsatizana pang'onopang'ono za: kutsimikizira kulondola kwa transmitter, kuchita kuwerengera munda, kupatula ndikusintha transmitter, ndikuwonjezera zolakwika zopitilira. Phatikizani zitsanzo za mayendedwe othetsera mavuto: yambani ndi mphamvu ndi chizindikiro, kenako mtundu wa echo, kenako macheke amakina.
Sungani zolemba za maphunziro ndi zizindikiro za luso. Konzani nthawi ndi nthawi zobwerezabwereza zomwe zikugwirizana ndi nthawi zowerengera.
Pemphani mtengo / Kuyitanitsa kuchitapo kanthu
Pemphani mtengo wa ma transmitter a Lonnmeter Guided Wave Radar omwe ali mu mzere ngati mukufuna kuyeza molondola kuchuluka kwa nayitrogeni m'mafakitale opanga ma wafer kapena matanki osungiramo zinthu zotenthetsera zotsekedwa ndi vacuum. Fotokozani kuti kugwiritsa ntchito kumaphatikizapo makina odzaza ndi kutulutsa thanki mosalekeza kotero kuti lingalirolo likugwirizana ndi nthawi yeniyeni yogwirira ntchito.
Mukakonzekera pempho la mtengo, fotokozani mfundo zofunika kwambiri zokhudza ndondomeko ndi makina.
Mtundu wa thanki ndi kuchuluka kwake (chitsanzo: thanki yosungiramo zinthu zotentha zotentha zodzaza ndi vacuum, 5,000 L), media (nayitrogeni wamadzimadzi), ndi kutentha ndi kupsinjika kwa ntchito;
kuchuluka kwa kudzaza ndi kutulutsa kosalekeza, nthawi yogwira ntchito, ndi mikhalidwe yoyembekezeredwa ya kukwera kapena kutsika;
malo okwerera, madoko omwe alipo, ndi mawonekedwe a malo olowera;
mulingo wofunikira woyezera, kulondola komwe kukufunika komanso kubwerezabwereza, komanso malire a alamu/malo okhazikika;
kuyanjana kwa zinthu zomwe amakonda komanso zoletsa zilizonse zoyeretsa kapena zodetsa za mafakitale opanga ma wafer;
kugawa malo oopsa ndi zoletsa zilizonse zoyika.
Kuti mupemphe mtengo kapena kukonza njira yoyesera, sonkhanitsani zinthu zomwe zatchulidwa pamwambapa ndikuzitumiza kudzera mu njira yanu yogulira kapena kulumikizana ndi injiniya wa malo. Kuchotsa deta ya pulogalamu kumathandizira kukula kwake ndikuwonetsetsa kuti pempho lotsogolera la radar la mafunde likugwirizana ndi ntchito zotumizira madzi m'mafakitale opanga ma wafer ndi makina osungira cryogenic.
Mafunso Ofunsidwa Kawirikawiri
Kodi njira yabwino kwambiri yoyezera kuchuluka kwa nayitrogeni wamadzimadzi mu thanki ku fakitale yopanga ma wafer ndi iti?
Ma transmitter a guided wave radar (GWR) inline level amapereka muyeso wopitilira, wolondola, komanso wosagwiritsa ntchito makina a cryogenic LN2 m'mafakitale opanga ma wafer. Amagwiritsa ntchito probe-guided microwave pulse yomwe imakhala yolimba motsutsana ndi nthunzi, kugwedezeka, ndi majini ang'onoang'ono a thanki. Pa matanki osungira cryogenic omwe amateteza vacuum, ikani transmitter yokhala ndi malo ocheperako komanso otsekedwa bwino kuti vacuum isunge bwino.
Kodi chotumizira cha radar cha mafunde chotsogoleredwa chingagwire ntchito nthawi zonse pamene kudzaza ndi kutulutsa mpweya kumapitirira?
Inde. GWR yapangidwa kuti izitha kuyeza mosalekeza pa intaneti ndipo imasunga mawerengedwe odalirika panthawi yogwira ntchito mosinthasintha. Kuyika bwino kwa probe, kukonza malo opanda kanthu a chipangizocho komanso malo opanda kanthu, komanso kutsimikizira ma echo kumaletsa ma echo abodza omwe amabwera chifukwa cha kuyenda kwa madzi. Chitsanzo: sinthani chotumiziracho mutachiyika pamene mukudzaza pamlingo wapamwamba kwambiri wa fakitole kuti mutsimikizire ma echo okhazikika.
Kodi chotumizira cha GWR level chimafanana bwanji ndi masensa osakhudzana ndi nayitrogeni yamadzimadzi?
GWR imatumiza ma microwave pulses kudzera mu probe, ndikupanga ma echo amphamvu komanso okhazikika mu nthunzi ndi mikhalidwe yovuta. Radar yosakhudzana ingagwire ntchito koma ingavutike m'ma tanki olimba kapena komwe kapangidwe ka mkati kamawonetsa zizindikiro. M'ma tanki okhala ndi zopinga zamkati kapena geometry yopapatiza, GWR nthawi zambiri imapereka ma echo obwerera bwino komanso ma readings okhazikika a LN2.
Kodi chotumizira mafunde chotsogoleredwa ndi radar chingakhudze kukhulupirika kwa vacuum m'matanki a cryogenic omwe amatetezedwa ndi vacuum?
Ikayikidwa ngati chotumizira chamkati chokhala ndi malo olowera ochepa komanso kutseka koyenera, GWR imachepetsa kuchuluka kwa malo olowera poyerekeza ndi masensa angapo osiyana. Malo olowera ochepa amachepetsa njira zotulutsira madzi ndipo amathandiza kusunga vacuum. Gwiritsani ntchito ma flange olumikizidwa kapena ma vacuum fittings apamwamba komanso zisindikizo zoyenerera za cryogenic kuti mupewe kuwononga vacuum ya thanki.
Kodi ma transmitter a radar otsogoleredwa amafunika kukonzedwanso pafupipafupi kapena kukonzedwanso nthawi zonse mu ntchito ya cryogenic?
Ayi. Magawo a GWR alibe ziwalo zosuntha ndipo nthawi zambiri amafunika kusinthidwa pang'ono. Kuzindikira komwe kumapangidwira mkati ndi kuyang'anira ma echo kumalola kuyang'ana malinga ndi momwe zinthu zilili. Chitani kutsimikizira kwa echo spectrum nthawi ndi nthawi komanso kuyang'ana momwe zisindikizo ndi probe zilili panthawi yotseka yomwe yakonzedwa.
Kodi ma transmitter a radar level ndi otetezeka kugwiritsidwa ntchito m'malo ovuta a semiconductor?
Inde. Ma transmitter a radar level amagwira ntchito pa mphamvu yochepa ya microwave ndipo sapereka chiopsezo cha tinthu tating'onoting'ono. Kulowa kwawo kochepa komanso kusalowa kwawo kumathandiza kusunga malo otetezedwa ku kuipitsidwa. Fotokozani zinthu zaukhondo, ma probe oyeretsedwa, ndi chitetezo choyenera cha kulowa mumlengalenga mukayika pafupi ndi malo oyera.
Kodi ndingasankhe bwanji pakati pa chotumizira cha GWR level ndi mitundu ina ya chotumizira cha liquid level cha LN2?
Gwiritsani ntchito mndandanda wosankha womwe umaika patsogolo kuyanjana kwa cryogenic, kutulutsa kosalekeza pa intaneti, kulimba kwa nthunzi ndi kugwedezeka, kulowa kochepa, kuzindikira, ndi kuthekera kophatikiza. Pa matanki ambiri a cryogenic fab fab, GWR ikukwaniritsa izi. Ganizirani za mawonekedwe a thanki, zopinga zamkati, komanso ngati muyeso wosinthika ukufunika.
Kodi ndingapeze kuti thandizo polumikiza chotumizira mafunde cha radar chomwe chimatsogoleredwa mu makina anga owongolera mafakitale?
Lumikizanani ndi gulu la akatswiri opanga mapulogalamu a transmitter kuti mupeze chithandizo chogwirizanitsa, chitsogozo cha kasinthidwe, ndi kuyang'anira mndandanda wazinthu zomwe zingagwiritsidwe ntchito. Angathandize pakutsimikizira ma echo, kuyika pansi, ndi mapu a DCS/PLC. Kuti mupeze mita yozungulira kapena ya viscosity yomwe imagwiritsidwa ntchito pamodzi ndi muyeso wa mulingo, funsani Lonnmeter kuti mudziwe zambiri za malonda ndi chithandizo cha ntchito chomwe chimagwiritsidwa ntchito pa mita yozungulira.
Kodi ndi njira ziti zazikulu zowunikira kukonza zomwe ziyenera kutsatiridwa pogwiritsa ntchito mita ya nayitrogeni yamadzimadzi?
Yang'anirani mphamvu ya echo ndi mbiri ya echo kuti muwone ngati pali kubweza kokhazikika komanso kobwerezabwereza. Yang'anirani chiŵerengero cha chizindikiro-mpaka-phokoso (SNR), zizindikiro za umphumphu wa probe kapena kupitirizabe, ndi vuto lililonse la transmitter kapena machenjezo. Gwiritsani ntchito njira zodziwira izi kuti mukonze nthawi yowunikira musanachite zolakwika.
Kodi kuchepetsa chiwerengero cha zida ndi chotumizira chosinthika kumakhudza bwanji mtengo wonse?
GWR yosinthika nthawi zambiri imatha kuyeza zinthu zomwe zili mu level ndi interface nthawi imodzi, kuchotsa ma transmitter osiyana. Izi zimachepetsa zipangizo zoyikira, zolowera, mawaya, ndi kukonza kwa nthawi yayitali. Kuchuluka kwa zida kumachepetsanso zolowera mu vacuum ndi chiopsezo cha kutuluka kwa madzi, zomwe ndizofunikira m'matanki osungiramo zinthu zotsekedwa ndi vacuum. Zotsatira zake zonse ndi mtengo wotsika wa umwini poyerekeza ndi zida zingapo zogwirira ntchito imodzi.
