Izihluzi zesikhumba esisikwe ngokulinganisa ngokuphelele ukusobala kwezinhlobo zokuhlanganisa

Kungani ukulinganisa kwezinhlobo zokusebenza kwezihluzi zesikhumba kuyisibonelo sokusebenza

Ukulinganisa kwe-±0.1 mm: Isidingo sokubanga kwezinhlobo zokaRinglock nezinhlobo zokuzimela

Izisikumbi zesikhundla esizimele njengokwesikhundla se-Ringlock kufuneka zibe nendlela eyodwa yokubala izinhlangothi ngokuphelele, ngoba ukungafani kahle kwezinhlangothi ngaphezu kwe-0.1 mm kungabangela ububi obukhulu ekubhalweni kwezindawo zokuthunywa kwemithombo. Uma lezi zindawo azizihlale kahle, amandla ayadistribuwa ngokungafanani kuzo zonke izindawo zomkhosi, okubangela izindawo ezizokuthunywa ngokusha kakhulu kunezinye. Lokhu kokuthunywa ngokusha kususa iziqephu zemetalu kahle ngokuphelele. Izifundo zibonisa ukuthi uma izipipi zezindlu zemithombo ezingaba yamagugu asebenza ngokuphelele kulezi zinhlangothi ezilula, kukhona ukuphulukana okugcwele ngokuphulukana kwe-30% kwezindlela zokuhlanganisa ngokwesifundo se-ISO 12811-1. Ukuphulukana okuncane kuyabangela ukuthi abasebenzi bade bephakemele kancane ukwenza izilinganiso emanzini, okuyabangela ukuthi bonke abaphambili bakhululekile kakhulu emsebenzini wokwakha.

Ukuthi Ukuphatha Kwesandla Semphephile Kuphula Ukuthunywa Kwesibhakabhaka Ngokuphulukana Kwe-42% (Kuvumelwe Yisiyenshi se-EN 10219)

Xa kusebenziswa ukugrinda kwemikhili, kufika ekutheni kubeka ubude bakwesikhala esincane kungapansi kwe-3.2 micrometers, okuyisibonelo sokususa iziphene ezingcwele ezikwenza ukuthi izicakathi zihlale kusuka emuva xa kunezinyathelo. Izimboni ezilandelayo izifundo ze-EN 10219 zibonisa ukuthi le ndlela yokuphatha iyakhulisa ukuthintana phakathi kwezinhlobo zemithambo nezicakathi zabo. Lokhu kusho ukuthi? Kukhona amaqembu amancane angaphansi kwezinto ozokuzilwa ngokungafani noma ngokungabiyo. Izifundo zibonisa ukuthi kukhona ukuphepha kwe-42 percent kule miphumela kulingana nezinhlobo ezingabiyo zezinhlobo zemithambo ezingabiyo. Isidingo esikhulu elinesibonelo sokuthi le ndlela iyahlinza ukuthi ukuphatha kwezinkampani zokuhlanza kuzinikeza kusuka kumgodi wokukhula kumfanekiso wemithambo. Lokhu kusho ukuthi kunezimilo eziningi zokuvikela isibhamu kusukela emuva kwezinsuku, futhi ukufaka kwezinhlobo zemithambo kubalulekile kakhulu ngoba zihlanganisa ngokuphelele kusuka kumillimeter ngasinye ngokuphelele kusukela emuva kwezinyathelo zokufaka ngokushesha emsebenzini.

Iziqu zemithambo yokuqondisa Ezinikeza Ukuthintana Kwezinhlobo Zemithambo

Umba, Ububanzi Bekhanda, Nokuthi Kwesiqephu: Izinhlobo Ezihlanganayo Zokuthintana Kwezinhlobo Zemithambo Nokuthintana Kwezinhlobo Zemithambo

Kodwa kusukela emaphipheni okuphakamisa, ukugqila ngokupheleleyo kuyisiphumo esihle kakhulu kubunzima besithembiso sesithembiso. Amaphiphe amaningi amahle ayisisekelo sokuthi isibalo sokufana kwesikhundla samaphiphe akhona ku-48.3 mm, ngokuchaza kwesibalo se-EN 39, oko kunika ukuthi ziyafana nezinkinga zonke noma izinkampani eziningi kumathuba okuphakamisa ngokwesiqondiso. Ububanzi besithembiso buyisifundo esibalulekile. Kuzo izinyathelo ezingaphansi, sizibona ububanzi be-3.2 mm, kodwa xa kuhamba kwezinyathelo ezilungileyo nokusebenza kwezimali ezinkulu, ububanzi obungaphezu kwe-4.0 mm buyidinga. Kuyikho nokuthi kukhona izimathematiki ezizenzela lokhu. Ukongeza ububanzi besithembiso ngokupheleleyo ngo-0.8 mm kungabika ukuthi kubhekiswe ngokupheleleyo ngo-30% ukuthi kubaluleke kakhulu ngokuchaza kwe-EN 10219-1:2006. Kuhlelwa yini umthwana? Isitshixo se-S355JR sibhekiswe kakhulu ngoba sibeka ubunzima obuhle bokuphuma. Izilimi eziningi zingavumela abasayensi ukwenza ububanzi besithembiso obuncane futhi baphumelela ngokupheleleyo kwezimali ze-20 kN/m². Lokhu wonke kufanya isiphumo sokubambisana kahle konke, ukusabalalisa amandla ukuze akho inkampani eyodwa ibe yinkulu kakhulu yezimali kuzo zonke izinyathelo zokubuyisa.

Ukugalvaniza Ngokuthi Uthakelwe Ematshini Ngokuphatha: Ukubalansha Ukukhathala Kwemithambo Nezinkinga Zokuphatha Izingxenye Ngokuphelele

Kodwa sifaka ukugalvaniza ngokufakwa kwezinkamba emanzini eshushu emva kokugrinda okuphelele, izinyathelo zihlala zinezidingo zazo zokuphelele futhi zihlala zingaphezu kwezinye ngokuphelele. Okudala kukuba le ndlela iyafaka isikolekethi sokuzinc esisodwa ngokuphelele esinamandla angu-85 microns, okuyisikhundla sonke isilinganiso se-ISO 1461. Kukholwa kakhulu ukuthi akukho yiliphi na ukuguqula kwamandla amancane ekupheleni kwalokhu kufakwa, okuhlinzeka konke kuleli phakathi lokugcina +/- 0.1 mm. Indlela enkulu yokuthuthukisa lapha kukuthi akukho ukungabikwa kwezindawo zokubhala noma kwezindawo zokugxilwa kwezinyathelo, okuyinto eyadala ngokuvamile kwezinkamba zokugalvaniza kabefore ukugrinda. Kulezi zinyathelo ozizigcina ezingaphansi kwezinkamba zomfula wempho, lokhu kwenza umphumela omkhulu. Izinyathelo ezifakwa ngalesi ndlela zihlala zisebenza ngokuphelele ngeminyaka eyi-8 uye ku-12 ngaphezulu kwezinye izinyathelo, futhi zihlala ziqiniseka ukuthi izindlela zokuxhumana ziyahlala zinezinkinga zokuxhumana zokuphelele ngaphezulu kwe-0.15.

Ukuchaza Kwempilo: Izinkamba Zokugcina Ezinamandla Ngokuphelele Kwezindlela Zokusebenza Eziningi

Ukubuyisela kwe-Platform ya-LNG yaseNtlanthini: Ukuphakamisa Ngokushesha Ngokugcina 27% Futhi Akukho Ikhulungu Lokubuyisela Kuphinda

Ukusebenza kwezindawo ezihlukene kuzokwakha izikhumba kuyenza ukusebenza ngazo kube yinkanisi ngaphezu kokuba kunezinye izinto zokuhlela ziyadlula ngokuphuma kwemithi yokukhumba kanye nokuthi kunezizwele zezwindi ezingathinti ngokuphambuka, okuyoba kuzokwakha izikhumba zisivule. Hlola umsebenzi wokugcina i-LNG wela ngo-2023 njengombuzo. Basebenzisa amapipi wezikhumba nezinhlobo zokubhalwa ngokuphakeme kwe-0.1 mm ngalokho, okuthinta isikhathi sokugcina ngokuphakeme kwe-25% futhi kususa kabanzi izinyathelo zokuvumela kabusha ozikhatshwa ngazo konke. Amapipe amahle aqhubeka nokufaka kabusha, kodwa lezi zibhala ngaphansi kwamazwindi angaphezu kwe-60 mph futhi ziqhubeke ngokuphuma kwemithi yokuhlaba ngokuphakeme kwezinsuku. Indlela yabo yokubhalwa kuyabonisa ukuthi abasebenzi abangakwazi ukubona ukuthi izinto ziyashisa ngaphansi kwezinye izinto. Izimboni zavuma ukuthi kukhona ukuphakama kwe-42% kwezinkinga zokushisa ngokulandela i-EN 10219, futhi izimodhuli ziyagcina ngokuphakeme kwezinye. Ngokujwayelekile, lokhu kucindezelela ukuthi kubhekwe kakhulu kwezinhlobo zokubhalwa, okuthinta izikhathi zokusebenza ngokuphakeme kwe-320, kubhekwe ukuthi izisebenzi ziyasebenza ngokuphakeme ngaphandle kokuthi kubekhona izinyathelo ezingasoloko, futhi akukho nzima yokuqondana ngokuphakeme kwezinye izinto ngokuphakeme kwezinye izinto ngokuphakeme kwezinye izinto. Lokhu kubonisa ukuthi izinhlobo zokubhalwa ziyakhomba ukuthi kubhekwe kakhulu kwezinhlobo zokubhalwa ngokuphakeme kwezinye izinto ngokuphakeme kwezinye izinto.

Imibuzo Evame Ukubuzwa

Kungani ukuthi ukulinganiswa kwe-±0.1 mm kubalulekile kumapipa esikhundleni?

ukulinganiswa kwe-±0.1 mm kubalulekile ngoba ukuchitha okunye kungahleli ukuthi izihlangothi zokulwa kuzilungile ngokuphelele, okubangela ukuthi amandla ayisikwe ngokungafanele nokuthi amandla ayizwa kusenzo esithile, okungaba yindlela yokugcina ukuchitha kwezinkambo zemithali.

Yini umbuso wokugrinda ngendlela yezindawo kumapipa esikhundleni?

Ukugrinda ngendlela yezindawo kuhlanza ubukhulu besikhundla kungapansi kwe-3.2 micrometers, okuhlanza izinkinga ezinokubangela ukuthi izihlangothi zihlale kungafanele. Lokhu kunciphisa ukuthi amapipa nezihlangothi zihlale kungafanele, kunciphisa ukuthi kuzokwenzeka ukuguqula okungakhathaleki, futhi kuhlinzwe ukuthi kungafanele ukuthi kufanele kubhekwe ukuthi kungafanele ukuthi kungabonakali ngokuvutha kwezincwadi.

Ukuthi ubude bekhanda busebenza njani kumthwalo wokusebenza kwezikhundla?

Izikhanda eziningi zinokuthi zibe nesivutha esingcono, nokuthi ukuthi ubude obungu-0.8 mm bukuhlanganisa ukuthi kunezimangwane ezingama-30% ezingcono kumthwalo wokulwa. Lokhu kukhona kubalulekile kubona ukuthi kungafanele ukuthi kungabonakali ngokuvutha kwezincwadi, ngokwesifundo sika-EN 10219-1:2006.

Kungani ukuthi ukuvutha kwezincwadi ngokuthi kwenziwa ngokuvutha kwezincwadi kubalulekile emva kokugrinda ngokuphelele?

Ukugalvaniza ngokuthi ubhala kwezinkulu emva kokugrinda kusinika ukuthi iziqephu zilahleke izintandokazi zabo ezithile ngaphandle kokuguqula izinhlaka. Kusinika ukuthi kubhekwe isibonelo esifanayo sesilika sokuzinc, okufundisa ukuthi iziqephu zizobuyela ngokuphelele kwezinye izinto ezihlukahlukene.

Ukuthi ukusakha okuphelele kwakwenza kanjani kumsebenzi wokugcina i-LNG yasezansi?

Ukusebenzisa amapayipi okusakha okuphelele nesilinganiso se-±0.1 mm sakhishisa isikhathi sokuhlanganisa umsebenzi ngu-27%, sasusa iziqu zokuhlanganisa kabusha, futhi sakhishisa izimfanelo zokuphambana, okwakuyisiphumo sokuthi kusavunyelwe amahora angu-320.
