    Ibyiza byo gukoresha spiral yazimiye arc isembuye ibyuma by'ibyuma byo gukora amazi yo munsi yubutaka

    Ibyiza byo gukoresha spiral yazimiye arc isembuye amabuye yicyuma kugirango imiyoboro y'amazi yo munsi yubutaka yerekanwe ishusho
    • Ibyiza byo gukoresha spiral yazimiye arc isembuye ibyuma by'ibyuma byo gukora amazi yo munsi yubutaka

    Ibisobanuro bigufi:

    Iyo ushizeho imirongo y'amazi munsi yubutaka, ni ngombwa guhitamo ubwoko bwumuyoboro mwiza kugirango hazamure irambye no kuramba. Amahitamo akunzwe kumirongo y'amazi yo munsi yubutaka ni umuyoboro usumbabunge usutswe, uzwi kandi nka Ssaw Icyuma.


    Ibisobanuro birambuye

    Ibicuruzwa

     Umuyoboro wa Ssawni ubwoko bwa spiral yazimiye arc umuyoboro usuye ukoreshwa mubice bitandukanye, harimo imirongo yubutaka. Inzira yacyo idasanzwe itanga imiyoboro minini-diamester hamwe nurukuta ruhoraho, bigatuma ari byiza gutwara amazi yo munsi yubutaka.

    Imwe mu nyungu nyamukuru yo gukoresha spiral yazimiye arc isembuye ibyuma ku mirongo yubutaka nimbaraga nyinshi nimbaraga zayo nyinshi. Inzira yo gusudira isukura itera umuyoboro ukomeye kandi wizewe ushobora kwihanganira igitutu nuburemere bwo gushyingurwa mu nsi. Izi mbaraga ni ingenzi mu gukumira kumeneka no guharanira ubusugire bw'igihe kirekire cy'imiyoboro y'amazi.

    Byongeye kandi, umuyoboro w'icyuma wa Ssaw urwanya ruswa, bituma bihitamo neza kubisabwa kubutaka aho imiyoboro ihura nubushuhe nibindi bintu bishingiye ku bidukikije. Itandukaniro ryo kurwanya ruswa rifasha kwagura ubuzima bwimiyoboro yawe kandi igabanya ibikenewe kubikorwa kenshi no gusana.

    Umuyoboro wo munda

    Indi nyungu yo gukoresha spiral yazimiye arc isesuye ibyuma byumuyoboro wubutaka nibihinduka no guhuza n'imihindagurikire. Inzira yo gusunika irashobora kubyara imiyoboro ya diamesters itandukanye, bigatuma bikwiranye na porogaramu zinyuranye z'amazi. Byongeye kandi, guhinduka kwicyuma ssaw byororoka kwinjiza no gukora, cyane cyane mubice bifite uburere cyangwa inzitizi.

    a. Uburyo bwa deoxidation bwagenwe kuburyo bukurikira:

    FF: Kwica byimazeyo ibyuma birimo ibintu bihwanye na bintrogen bingana no guhambira azote iboneka (urugero: 0,015%!

    b. Agaciro ntarengwa kazonga ntigikurikizwa niba imiti yimiti yerekana ibintu byibuze 0,020% byibuze byibuze 6: 1, cyangwa niba ibindi bintu bihagije bya N-bice bihari. Ibintu n-guhuza byandikwa mu nyandiko.

    Usibye imbaraga, kuramba, no guhinduka, kuzunguruka arc gusudira ibyuma bisuye byagereranijwe ugereranije nubundi bwoko bwa pipe. Inzira yo gusudira igura igabanya ibiciro byumusaruro, bigatuma ubukungu bwubukungu bwimishinga minini yamazi. Kurambagiza igihe kirekire hamwe nibisabwa mu buryo buke bwo kubungabunga umuyoboro wa Ssaw kandi bitanga umusanzu muri rusange kuzigama amafaranga yo kuzigama hejuru yubuzima bwumurongo wamazi.

    Umuyoboro wa Ssaw

    Muri rusange, hari ibyiza byinshi byo gukoresha spiral yarengeye ibyuma bya arc ibyuma byubutaka, harimo imbaraga nyinshi, kuramba, guhinduka, no gukomera, no gukora neza. Iyi mico igira uburyo bwizewe kandi bufatika kubutwara amazi yo munsi yubutaka, haba kubikorwa remezo bya komini, porogaramu zinganda, cyangwa ibikorwa byubuhinzi.

    Muri make, mugihe cyo guhitamo umuyoboro mwizaKu mirongo y'amazi yo munsi y'ubutaka, spiral yazimiye arc isesuye ibyuma ni amahitamo meza. Kubaka gusudira gusudira bitanga imbaraga, kuramba hamwe no kwanga kwangirika bikenewe imikorere yigihe kirekire, mugihe guhinduka no gukora ibiciro bikaba bituma bituma bituma habaho amahitamo meza yimishinga y'amazi yubunini bwamazi. Muguhitamo spiral yazimiye arc isembuye ibyuma, urashobora kwemeza kwizerwa no kuramba byumurongo wamazi yawe munsi yubutaka, ukaguha amahoro yo mumutima, akaguha amahoro yo mumutima no kwigirira ikizere muri sisitemu y'amazi.
