Izembozo Zesilo Zokugcina Impushana Yenjoloba Ekhwalithi Ephezulu Yobunjiniyela
Isivalo se-silo yokugcina impushana yerabha sinemisebenzi emibili: ukugcina uthuli ngaphakathi nokuvimbela amanzi ukuthi angangeni. Uphahla kufanele luqine ngokwanele ukuthwala umoya neqhwa, luvaleke ngokwanele ukubamba umfutho omubi wokuqoqa uthuli emaphethelweni, futhi lwenziwe ngendlela yokuthi amanzi okujiya angagobhozi ngodonga lwangaphakathi ehlela empushaneni. Ku-silo ehlanganiswe ngamabhawudi lokhu kusho ukuthi i-rim flange yabiwe phakathi kwamaphaneli ogobolondo nophahla, izihlanganisi ezinama-EPDM gasket, amabhawudi ezinga le-8.8, kanye nefomu lesivalo elikhethwe ngokusho kwesimo somthwalo wendawo, ngokuvamile i-aluminium geodesic dome eklanyelwe i-AWWA D108 noma i-API 650 enomoya neqhwa ngokwe-ADM 2015 ne-ASCE 7-10. Ugobolondo lwangaphakathi olune-enamel lungaba yinsimbi ehlanganiswe nengilazi ene-Ra engaphansi kuka-0.8 µm ukuze kube lula ukuyihlanza.
I-rubber powder iyisici esiqinile esinzima esisakazekayo ngenxa yalokho esingakho. Ilula, inegesi elingaguquki, iyahlangana, iqina ngaphansi kwesisindo sayo lapho umswakama ujikeleza, futhi zonke izindawo zokudlulisa zikhiqiza uthuli olungeke lwavalwe ngokuphelele isihluzi esiphathwayo sokuqoqa. I-silo yokugcina iba yithuba lokugcina lokugcina lolo thuli endaweni eyodwa ngaphambi kokuba lufike emgwaqeni wemboni. Amaqembu enza amakhava e-silo yokugcina i-rubber powder yekhwalithi ephezulu ngokuvamile abhekana nezimpawu ezintathu ngesikhathi esisodwa: uthuli oluphuma emaphethelweni ophahla, ukujiya kwamanzi okudonsa emkhiqizweni, kanye nophahla okufanele lususwe noma lusikwe njalo lapho i-silo ilayishwa. Izixazululo ziyi-geometric ne-mechanical kunokuba zibe ngokwedlulele, yingakho kufanele kucaciswe kusenesikhathi.
Okufanele isembozo simelane nakho
Umoya, iqhwa, ingcindezi yokuqoqa uthuli kanye nothuli lomkhiqizo yizimo zomthwalo ezine ezizimele. Uphahla luthatha ukuphakama komoya kanye nomthwalo weqhwa endaweni yangaphandle, futhi lezo zindinganiso zivela endaweni hhayi ku-silo. Ngaphezu kwalokho, uhlelo lokuqoqa uthuli olunamathiselwe ku-silo ludonsa ingcindezi encane engemihle emaphethelweni kanye nasendaweni yokungena yomkhiqizo, ngakho isembozo kufanele sihlale sibambelele ngaphansi kwaleyo suction esikhundleni sokuphakama noma ukunyakaza. Ekugcineni isembozo ngokwaso siwumngcele wothuli: igebe emaphethelweni, isivalo esixegayo, noma umnyango wokungena wesandla ongavalwa kahle kwenza i-silo yonke ibe umthombo wothuli ngesikhathi sokukhipha.
Isimo sesithathu somthwalo abantu abasikhohlwayo umhwamuko ojikayo. Isilo esisimweni sezulu esinomswakama, noma esigcwaliswe sifudumele sabe sesiphola, sizojuluka ebusweni bangaphakathi. Lawo manzi ehla ngodonga ewele empushaneni, okuyinto eyenza impushana yenjoloba egeleza ngokukhululeka ibe yiqhuqhuva elibhakiwe. Ikhambi ukuthatha indlela yomhwamuko ngokungathi sína: vala uphahla, vumela umoya noma susa umswakama endaweni yekhanda ngokokuklama, futhi uthambekise izindawo zangaphakathi ukuze noma yimaphi amanzi ajikayo afinyelele emseleni esikhundleni somkhiqizo.
Amafomu okumboza e-silo eboshiwe
Khetha uhlobo lwophahla kusukela esimweni somthwalo kanye nesidingo sokungena. Uphahla lwekhoni olungashoni luyinto eshibhe kakhulu futhi alulusingathi kahle iqhwa ezindaweni ezinomthwalo osindayo, ngoba umthambeka kufanele ube mkhulu ukuze kudinge iqhwa futhi lokho kubiza indawo yekhanda. Idome le-geodesic le-aluminium lisabalalisa umthwalo ngendlela efanele, lilula ngokwanele ukuthi igobolondo alidingi ukuqiniswa okusindayo, futhi liyincazelo evamile yamasiilo amakhulu anezibophelelo ezinobubanzi obukhulu; lakhiwe ngokwe-AWWA D108 noma i-API 650 ngomthwalo womoya neqhwa obhekiselwe ku-ADM 2015 kanye ne-ASCE 7-10. Uphahla lwepulangwe oluyisicaba noma olunomthambeka omncane olunezibophelelo olunesakhiwo esakhiwe ngamafreyimu lungenye indlela lapho isitshalo sesivele sisebenzisa uhlelo olufanayo lwamaphaneli noma lapho uphahla luyindawo yokusebenzela.
Noma yiliphi ifomu, imininingwane yomugqa iyafana: i-flange yophahla iboshelwa engxenyeni ephezulu yegobolondo nge-EPDM gasket, amabhawudi ezinga le-8.8 azungeze umjikelezo ogcwele, kanye nekhava yangaphakathi yomugqa eqhubekayo ukuze uthuli lungakwazi ukungena emseleni. Ukususwa ukuze kuhlanjululwe noma ukuvulwa kwe-hatch yophahla kufanele kwenzeke ngaphandle kokusika igobolondo.
Ngaphakathi kwe-silo: impahla, i-geometry kanye nokuhlanzeka
Ukuziphatha kwempushana kunquma phansi kanye nodonga, isembozo sinquma uthuli. Kumphushana werabha ehamba ngokukhululeka, kuvame ukukhethwa phansi oyisicaba esinokukhishwa komoya noma ngesikulufu ngoba izinga elisele liphansi futhi phansi kulula ukushanela; phansi kwehopper noma kwefunnel kunikeza ukukhishwa okuphelele kodwa kudinga i-engeli yodonga emile kakhulu kanye nesikhala esengeziwe esingenhla. Impahla ethambekele ekunqwabelaneni ingase ifune phansi oyiconical kanye nokudlidliza noma i-aerated pad, futhi isembozo kufanele samukele lezo zinto ezingena ngaphakathi. Noma ngabe yikuphi phansi, indawo yangaphakathi ibalulekile: udonga lwensimbi ehlanganiswe nengilazi olushiswe ku-820 kuya ku-930 °C olunongqimba lwe-enamel olungu-0.25 kuya ku-0.45 mm kanye nokhahlelo lobuso olungaphansi kwe-Ra 0.8 µm kunikeza indawo engenasikhala, elula ukugeza, okubalulekile lapho isilo sihlanzwa phakathi kwezigaba zomkhiqizo. I-enamel ihlanganisa i-pH 1 kuya ku-14, ngakho ngisho nomsebenzi wempushana exubile uhlala ngaphakathi kwesembozo solweluko.
I-static iyingozi ethile ye-rubber powder. I-rubber powder eyomile ayivumeli ugesi futhi igcina umthwalo, ngakho hlanganisa igobolondo, uphahla nanoma iyiphi insimbi yangaphakathi kugridi yokuthungela yesikhungo futhi gcina izinga lokugeleza komkhiqizo lingaphakathi kobubanzi obunconywayo bento. Isembozo siyingxenye yalolo hlelo, hhayi isengezo salo.
