Izikhunta Ezilingana Ne-Cadweld ezivela eShayina: Umhlahlandlela Wosonkontileka Wokucaciswa, Ukuhambisana Nezindleko

IseshaIzikhunta ezilinganayo zeCadweldngokuvamile kusho enye yezinto ezintathu: ithenda yakho ichaza i-Cadweld ngegama futhi ivumela "noma ivunyelwe ngokulinganayo", iqembu lakho selivele linama-handle clamps futhi udinga ama-mold afanelana ne-geometry yokuxhumana efanayo, noma umane uqhathanisa intengo yegama lomkhiqizo nalokho okukhokhiswa yifektri yaseShayina nge-graphite preform mold efanayo. NginguJane Yang, umphathi wokuthengisa e-Xinchang Shibang New Material — ifektri yethu ibilokhu ikhiqiza ama-exothermic welding molds iminyaka engaphezu kwengu-17 — futhi kulo mhlahlandlela ngichaza indlela yokuchazaenye indlela yokubumba isikhunta sokushisela esishisayongakho-ke kuyahambisana ngempela, ukuthi umehluko wezindleko oqotho ubonakala kanjani, nokuthi yibuphi ubufakazi bokufaneleka obuhlukanisa okulingana kwangempela kokubukeka okushibhile.

TL;DR

  • I-Cadweld uhlobo lwe-nVent ERICO — olune-patent ngo-1939, olunezixhumanisi ezingaphezu kwezigidi eziyi-100 ezifakiwe — ngakho-ke igama elithi “Cadweld-equivalent” lisho isikhunta esenziwe ngendlela efanayo yokuxhumana kanye nenqubo, hhayi isikhunta esenziwe yi-nVent.
  • Izinombolo zezingxenye zomkhiqizo wethu wefektri ezibhekisela kuzo zonke izinhlobo zivela kumaphuzu amane edatha kuphela: uhlobo loxhumano (umndeni wesikhunta), usayizi womqhubi wokugijima, usayizi womqhubi wompompi, kanye nobubanzi benduku noma bomphezulu.
  • I-IEEE Std 80 ilinganisa ukuxhumeka okushisiwe kwe-exothermic ku-1,083 °C ngokumelene no-250–350 °C kwezixhumi zohlobo lokucindezela, kanti i-IEEE 837 ifanelekela ukuxhumeka kwesiteshi esingaphansi okuhlala njalo — ibamba noma yikuphi ukubumba okulinganayo nezinkomba ezimbili ezifanayo.
  • Ezicaphunweni zethu zokuthumela ngaphandle, isikhunta esilingana nefektri yaseShayina sivame ukuba ngaphansi kuka-40-60% kwesilinganiso segama lomkhiqizo, ikakhulukazi ngoba intengo yeqa izendlalelo zokusabalalisa - kodwa isilinganiso se-graphite kanye ne-powder yikhona kanye lapho kungafanele uvumele umhlinzeki ukuthi akhokhe khona.
  • Sisebenzisa izikhunta zomshini ezilinganiselwe imijikelezo yesevisi engu-50-100 (amalunga angu-80-100 asetshenziswa ensimini), ezihlolwe yi-CEPRI, ngezingcezu ezingu-10,000 ngenyanga, ezibhekiselwe kunombolo yakho yengxenye noma kushejuli yomqhubi.
Isikhunta sokushisela se-graphite exothermic esilingana ne-Cadweld esivela efektri yaseShayina — isimiso esifanayo se-preform graphite njengohlobo lokuqala lomkhiqizo
Isikhunta se-graphite esilingana ne-Cadweld esivela kumugqa wethu wokukhiqiza: isimiso esifanayo se-preform graphite, ukwakhiwa okufanayo kwamabhulokhi amabili, okufakwe ngomshini kwinhlanganisela yomqhubi oyichazile.

Lokho Okushiwo Yi-“Cadweld-Equivalent” Empeleni — Nalokho Engakushoyo

Siqala yonke ingxoxo yokulingana ngokwethembeka kwezimpawu zokuhweba, ngoba osonkontileka bashiswa amagama angacacile.I-Cadweld iwuphawu olubhalisiwe lwe-nVent ERICO: UDkt. Charles Cadwell wasungula le nqubo ngo-1938, i-ERICO yanikeza ilungelo lobunikazi ngo-1939, kantiIkhasi lomlando le-nVent ERICO Cadweldiqopha ukuxhumeka okungaphezu kwezigidi eziyi-100 okufakiwe kanye nesici esibalulekile ngo-2014 — I-Cadweld yaba uhlobo lokuqala lokuxhumeka ukudlula iziqu ze-IEEE 837-2014 zokufaka isisekelo esiteshini esincane. Sitshela osonkontileka ngokusobala: akekho "olingana" nozuza lelo rekhodi ngokugomela.

Sichaza ukuthi yini enikezwa yisilinganiso ngokusemthethweni: i-physics efanayo ku-geometry efanayo. Inqubo ye-exothermic — i-copper oxide kanye ne-aluminium powder esabela ku-graphite crucible ukuze ithulule ithusi elicibilikisiwe phezu kwama-conductor — cishe ineminyaka eyikhulu ubudala futhi ayiyona eyayo. Imindeni yesikhunta (i-GT, i-GR, i-TA, i-SS, i-VS, i-XA kanye nokunye) iyi-geometri yokuxhuma: i-tee evundlile entongeni eqondile, i-cable splice, ikhebula eliya endaweni yensimbi.Isikhunta esilinganayo sithola igama laso lapho i-geometry yaso yesikhala, indawo yembobo kanye neshaja yempuphu kukhiqiza ukuxhumana okufanayo okwenziwa yisikhunta somkhiqizo.— futhi lapho umenzi wayo engakufakazela ngedatha yokuhlola kunezichasiso.

Impendulo kaNugget: "I-Cadweld-equivalent" iyisimangalo se-geometry kanye neziqu, hhayi isimangalo somkhiqizo. Ngobaukusabela kwe-exothermic ngokwako kuyikhemikhali engenalo ilungelo lobunikazi elineminyaka eyikhulu ubudala kuyilapho igama le-Cadweld kanye nerekhodi lalo lokuxhumana eliyizigidi eziyi-100 kungokwa-nVent ERICO, umakhi kufanele athenge izinto ezilingana ne-cavity geometry kanye nobufakazi be-IEEE 837-grade - futhi kufanele aphathe noma yimuphi umhlinzeki ofiphaza umugqa womkhiqizo njengengozi, hhayi isivumelwano. 

Emsebenzini wethu wokuthumela kwamanye amazwe sibona izimo ezintathu ezisemthethweni zokusetshenziswa kwezilinganiso ezifanayo - futhi sicaphuna kuzo zonke ezintathu masonto onke. Okokuqala, amathenda abhalwe ukuthi “Cadweld noma evunyiwe elinganayo”, lapho ukuvunyelwa kuncike kumadokhumenti. Okwesibili, amaqembu alinganisa uhlelo olulodwa lwe-handle-clamp oludinga imindeni eyengeziwe yesikhunta ngobuningi. Okwesithathu, abasabalalisi bakha uhlobo lwendlu lwe-isikhunta se-thermitizinto ezisetshenziswayo ezinezimpawu ze-OEM — isevisi esiyiqhuba njalo.

Imininingwane: Amaphuzu Amane Edatha Adingwa Yifektri YaseShayina

Sibona osonkontileka belahlekelwa amasonto ngenxa yemibuzo engacacile efana nokuthi “intengo yesikhunta seCadweld ngicela”. Sifundisa abathengi ukuthi isikhunta siyi-negative eyenziwe ngomshini yoxhumano olulodwa oluthile, ngakho-ke incazelo iwuxhumano. Ikhathalogi ye-nVent ichaza indlela enengqondo ngayo ngokusebenzisa uhlelo lwayo lokufaka izinombolo zesikhunta — inombolo ngayinye yengxenye ifaka ikhodi yohlobo loxhumano, ukhiye wentengo kanye nosayizi womqhubi, kanye nekhathalogi abayakhile izinhlobo zoxhumano ezingaphezu kuka-45,000. Ifektri yethu idinga amaphuzu edatha amane kuphela ukuze ibhekisele kunoma iyiphi yazo:

  • Uhlobo lokuxhuma (umndeni wesikhunta).I-T-shirt to ground rod tee (GT), i-cable to rod end (GR), i-cable-to-cable tee noma i-splice (TA/SS), i-cable to steel surface (VS), i-cable-to-cable cross (XA), njalo njalo. Isithombe somdwebo wekhathalogi yomkhiqizo siyasebenza uma ungayazi ikhodi.
  • Usayizi womqhubi wokuqalisa.Umqhubi oqhubekayo — isibonelo i-4/0 AWG concentric, 120 mm², noma i-19/#9 Copperweld. Isimo sokunamathela kanye nezinto, ngoba abaqhubi be-CCS bashisela ngendlela ehlukile kunethusi elidonswe kancane.
  • Usayizi womqhubi wethephu.Umqhubi wegatsha, uma uxhumano lunalo.
  • Ububanzi benduku noma bomphezulu.Ukuze kuxhunywe induku, ububanzi benduku obujwayelekile (5/8 in, 3/4 in) kanye nezinto zenduku (eziboshwe ngethusi vs eziboshwe nge-galvanised zishintsha umgodi); ukuze kufakwe amapayipi noma ubukhulu obuyisicaba.
Isikhunta sokushisela esivulekile esiveza i-crucible kanye nomgodi womqhubi — i-geometry okumele ichazwe yincazelo
Isitsha esivuthayo kanye nomgodi wesikhunta esivulekile: thola uhlobo loxhumano kanye nosayizi womqhubi ofanele futhi le geometry ifanelana nobukhulu obulinganayo bomkhiqizo bobukhulu.

Kungani i-geometry ifanelwe yilolu qina?Ngenxa yokuthi i-IEEE Std 80 ilinganisa izinhlobo zokuxhumeka ngokushisa kwephutha, ziyasinda: izixhumi zohlobo lokucindezela ku-250–350 °C, izixhumi ezihlanganisiwe ku-450 °C, kanye nezixhumi ezihlanganisiwe ze-exothermic ku-1,083 °C.— ithebula livela ku-Ikhathalogi yobuchwepheshe ye-nVent ERICO CadweldSixwayisa abathengi ukuthi leli gumbi lokushisa yilokho kanye okulahlwa yimbobo engakahlelwa kahle: imbobo enkulu kakhulu iqeda ukushintshwa, enye encane ikhipha ithusi elicibilikisiwe emthungweni wesikhunta, futhi zombili lezi ziphazamiso ziyacasha kuze kube yilapho kutholakala ugesi wephutha.

Impendulo kaNugget: Amaphuzu amane edatha — uhlobo lokuxhumana, usayizi wokugijima, usayizi wempompi, ububanzi benduku — achaza ngokugcwele noma yisiphi isikhunta se-exothermic. Ngobaisikhunta simane nje siyi-negative efakwe ngomshini yokuxhumeka okukodwa, ifektri enalezi zindinganiso ezine (noma inombolo yengxenye yomkhiqizo yokuzichaza) ingabhekisela kuzinkulungwane zezinhlobo ezifakwe kukhathalogi ngaphandle kokushintshaniswa okukodwa kokudweba. 

Ukuhambisana: Izinombolo Zezingxenye Zomkhiqizo Ezibhekisela Kuwo Wonke Umuntu Ngaphandle Kokuqagela

Siphendula imibuzo yokuhambisana nsuku zonke, futhi ihlukaniswe yaba izinhlobo ezintathu, ngayinye inempendulo ehlanzekile:

  • Ingabe isikhunta esilinganayo sizofanelana nezibambo zami zezibambo ezikhona?Siyaqinisekisa ukuthi kumajiyometri amaningi bayakwenza — isikhunta samabhulokhi amabili esine-clamping yangaphandle siyindlela evamile embonini. Siyaqinisekisa ukuhambisana kwe-clamp ngokumelene nohlobo lohlaka (i-clamp yesitayela se-L160 ihlanganisa isikhunta se-C, Q kanye ne-R price-key ohlelweni lomkhiqizo) ngaphambi kokuthi sicaphune, futhi sihlinzeka nge-clamps ezihambisanayo lapho ozimele beqembu lakho bengalingani.
  • Ingabe izinto zokushisela zomkhiqizo wami zizosebenza ku-mold efanayo?Siphendula ngoyebo uma ivolumu yesikhala ifana — osayizi bekhatriji (#90, #115, #150, #200, #250, #500) bayisisindo sokushaja, futhi isikhala esibhekiselwe kahle sithatha ishaja efanayo. Sithumela isikhunta ngasinye ngosayizi wekhatriji waso ocacisiwe omakwe, futhi sixuba impuphu yethu nezinto zakho zomqhubi ukuze ungavalelwa ezintweni ezidliwayo zomkhiqizo.
  • Ingabe ukushisela ngokwako kuzophumelela ukuhlolwa?Lowo ngumbuzo wokufaneleka, hhayi umbuzo wokuhambisana - futhi yilapho okulinganayo kufanele kubonise ubufakazi. Sikhiqiza amalunga aqediwe aphethe amandla afanayo namanje njengomqhubi futhi siphumelele ekuhlolweni okubonakalayo; izikhunta zethu ze-AF-0408 zikhiqiza amalunga angahlukaniseki kumalunga esikhunta somkhiqizo ekuqedeni kwesigaba kanye nobuso.
Isampula yejoyinti elihlanganisiwe le-X-cross exothermic elihlanganisiwe elenziwe ngesikhunta esihambisana ne-Cadweld
I-X-cross cable-to-cable joint ehlanganiswe nenye yezinhlobo zethu zokubumba: i-full fusion, ayikho i-porosity, ilinganiswe ngomthamo womqhubi — izindlela zokwamukela ezibonakalayo ziyafana nenqubo yomkhiqizo.
Impendulo kaNugget: Ukuhambisana kufakazelwe ngamaphuzu amathathu: isikhombimsebenzisi se-handle clamp, ivolumu yokushaja yempuphu, kanye nesigaba sokushisela esiqediwe. NgobaAma-clamp esibambo, izisindo ze-cartridge kanye ne-geometry ye-cavity kuyizilinganiso ezijwayelekile embonini kunokuba kube yizo ezizimele, isikhunta esilinganayo esibhekiselwe kahle siwela emsebenzini weqembu elikhona ngaphandle kokuqeqeshwa kabusha — kodwa kuphela uma umhlinzeki ehlola wonke amaphuzu amathathu ngaphambi kokuthunyelwa, yingakho siqinisekisa ukuthi i-clamp ihambisana nokubhala nayo yonke ikhotheshini. 

Izindleko: Lapho Umehluko Ongu-40–60% Uvela Khona — Nalapho Kungafanele Uvele Khona

Sibonisa osonkontileka izibalo eziqotho.Ezicaphunweni zethu zokuthumela ngaphandle, isikhunta esilingana nefektri yaseShayina sivame ukubiza ngaphansi ngo-40-60% kunesilingana negama lomkhiqizo, ikakhulukazi ngoba intengo yeqa izendlalelo ezimbili noma ezintathu zokusabalalisa phakathi kwefektri nendawo.Ekubizeni kwethu, i-graphite, imishini kanye ne-powder kuyizindleko zangempela kuyo yomibili imikhiqizo; i-premium yomkhiqizo ikhokha ikhathalogi, isitoko sendawo kanye nerekhodi lokuxhumana eliyizigidi eziyi-100 — konke kuyigugu ngempela, futhi konke kubiza ngentengo.

Isikhunta segama lomkhiqizo uma kuqhathaniswa nesilingana nefektri yaseShayina: umehluko wezindleko wenziwe ngani
Ingxenye Yezindleko/Inani Isikhunta Esibizwa Ngegama Lomkhiqizo Okulingana Nefektri (Okwethu)
Intengo yesikhunta ehlobene (kusukela kuma-quotation ethu) Isisekelo 100% 40–60% ngaphansi kwesisekelo, ikakhulukazi kusukela ekweqeni izendlalelo zokusabalalisa
Ikhwalithi yomzimba we-graphite Kulawulwa, kubhaliwe phansi Kumelwe kudingeke: i-graphite yekhwalithi yokumelana nokushisa okuphezulu kanye nophawu oluphelele — eyethu ilinganiswe ngemijikelezo engu-50–100
Impilo yesikhunta ebhalwe phansi Kuchazwe ngekhathalogi Impendulo yethu yasensimini ihlanganisa amalunga angu-80–100; thola ngokubhaliwe kunoma yimuphi umhlinzeki
Igumbi lokulungisa amaphutha (IEEE Std 80) Isilinganiso sokuxhumeka esingu-1,083 °C uma sishiselwe kahle Isilinganiso esifanayo esingu-1,083 °C — i-process physics iyafana; ukunemba kwesikhala yikona okusilondolozayo
Ubufakazi bokufaneleka I-IEEE 837-2014 idlulile (uhlobo lokuqala lokuxhumeka, 2014) Umkhiqizo ohlolwe yi-CEPRI + ukuhlolwa kwangaphambi kokuthunyelwa komuntu wesithathu (SGS/BV) uma kuceliwe
Isikhathi sokuhola kanye ne-MOQ Isitoko sokusabalalisa semindeni evamile Isikhathi sokuhola efektri; imindeni evamile evela kuma-MOQ amancane, okukhethekile okwenziwe ngomshini ukuze ku-odwe
Okungamelwe neze kulungiswe ngokwezomnotho Ibanga le-graphite kanye nokwakheka kwempuphu — isikhunta esifa emajoyintini angu-30 noma isilinganiso sempuphu ejwayelekile sisusa yonke imali eyongiwe ekuthengeni kabusha kanye nokushintshwa kwe-welds okuhlulekile
Impendulo kaNugget: Thenga okulingana nokonga ukusatshalaliswa, kuhlole ukuze ubone ikhwalithi esebenzisekayo. Ngobaigebe lentengo elingu-40–60% livela esakhiweni sesiteshi kune-physics, lingokoqobo futhi liyabanjwa — kodwa igebe elifanayo lilinga izimboni ezibuthakathaka ukuthi zinciphise ubuningi be-graphite kanye nesilinganiso se-powder, ngakho-ke imibuzo yokuhlola yomakhi kumele ihlose lapho ngqo. 

Sinikeza elinye iphuzu lokwethembeka: uma igama lakho lethenda uCadweld lingenalo isigatshana "noma esilinganayo", thenga uhlobo lomkhiqizo. Siyawenqaba lawo ma-oda ngokwethu, ngoba okulinganayo okushintshwa esikhundleni sencazelo evaliwe kubeka inkontileka yakho - kanye nedumela lethu - engcupheni. Sikholelwa ukuthi okulinganayo kufanele kube yimininingwane evulekile, izinhlelo zohlobo lomkhiqizo wasekhaya kanye nemikhumbi esezingeni elifanele yosonkontileka.

Bamba Okufanayo Nezinga Elifanayo: Ubufakazi Bokufaneleka Okufanele Ubufune

Sigcizelela ukuthi osonkontileka basebenzise uhlaka lokubhekisela komphakathi nakithi:I-IEEE 837ifanelekela ukuxhumeka okuhlala njalo okusetshenziswa ekusekelweni kwesiteshi esincane — ukushintshwa ngaphakathi kwegridi, izintambo ezixhunywe kuyo, kanye nezintambo eziya emishinini nasezinhlakeni.I-IEC 62561-1ibeka izidingo kanye nokuhlolwa kwezingxenye zokuxhumeka ezivikela umbani, ukuxhumeka kwe-exothermic kufakiwe ngokusobala. Siphatha irekhodi le-nVent uqobo — uhlobo lokuqala lokuxhumeka oludlula i-IEEE 837-2014 — njengesilinganiso uhlobo lomkhiqizo oluthenge ngalo i-premium yalo, futhi lichaza ukuthi kusho ukuthini “okulinganayo” ephepheni.

Sithola amadokhumenti amathathu ahlukanisa umhlinzeki olinganayo ofanelekayo ohlwini lwemakethe:

  • Ukuhlolwa komkhiqizo komuntu wesithathu.Ukukhiqizwa kwefektri yethu kuhlolwa yi-I-CEPRI (Isikhungo Socwaningo Lwamandla Kagesi saseShayina)— buza noma yimuphi umhlinzeki ohlola eyakhe, bese ulindela isikhungo esiqanjwe igama, hhayi igrafu yebheji.
  • Isitifiketi sekhwalithi yesistimu.Sisebenza ngaphansiI-ISO 9001:2015ukuphathwa kwekhwalithi, okuqinisekiswe ekhasini lereferensi le-ISO — inombolo yesitifiketi kufanele ibe sekhotheshini, hhayi nje kulogo.
  • Ubufakazi bokushintshwa kwezinga leqembu.Isilinganiso sokuphila kwesikhunta ngokubhala (esethu: imijikelezo engu-50–100), amarekhodi e-powder batch ahambisana nesheduli yakho yomqhubi, kanye nokuhlolwa kokuthunyelwa ngaphambi kokuthunyelwa yi-SGS noma i-Bureau Veritas uma i-oda likuvumela.
Impendulo kaNugget: Isikhunta esilinganayo sihle kuphela uma sifaka ubufakazi baso. NgobaI-IEEE 837 kanye ne-IEC 62561-1 zifanelekela ukuxhumeka okuqediwe esikhundleni samakhathalogi, umzimba wokuhlola womhlinzeki, ukungena kwerejista yesitifiketi kanye namarekhodi okuhlolwa kwebhetshi yiwona umkhiqizo — isikhunta esithunyelwe ngaphandle kwawo asaziwa, kungakhathaliseki ukuthi isaphulelo siyini. 

Yakha Isicelo Sakho Sokubhekisela Kwesikhunta

Sakhe leli thuluzi ukuze liphendule ngqo umbuzo esifuna ukuwuthola — gcwalisa amaphuzu amane edatha bese libhala umucu wemininingwane ongayinamathisela ku-imeyili kithi noma kunoma yimuphi umhlinzeki:

Umakhi Wezincazelo Zesikhunta





Imininingwane yakho yokusalungiswa izovela lapha.
Impendulo kaNugget: Incazelo yemigqa emine ithatha indawo yenyanga yokudweba i-ping-pong. NgobaUxhumano ngalunye lwe-exothermic olufakwe kukhathalogi luchazwa ngohlobo loxhumano, usayizi wokugijima, usayizi we-tap kanye nobubanzi benduku, okuthumela lawo manani amane (noma inombolo yengxenye yomkhiqizo ewafaka ikhodi) kuvumela ifektri ukuthi isho isikhunta esihambisanayo, usayizi wekhatriji yayo kanye ne-handle clamp yayo empendulweni eyodwa. 

Kungani Abakhiqizi Bezinkontileka Bethenga Izikhunta Ezilinganayo Embonini Yethu

Singumthombo womshini wokugaya, hhayi ideski lokuhweba. Ifektri yethu, i-Xinchang Shibang New Material, ikhiqize imikhiqizo yokuvikela umhlaba kanye nombani iminyaka engaphezu kwengu-17 evela e-Xinchang, e-Zhejiang, amahora amabili ukusuka emachwebeni ase-Ningbo nase-Shanghai. Iphrofayili yethu esemthethweni yenkampani iqopha irekhodi elilinganiselwe:imikhiqizo ithengiswa emazweni angaphezu kwama-60, ifektri engamamitha-skwele angu-3,000 enabasebenzi bokukhiqiza abangaphezu kwama-40 kanye nabasebenzi be-R&D aba-5, umkhiqizo wanyanga zonke ongaphezu kwezingcezu ezingama-200,000, kanye nokuthunyelwa kwamanye amazwe okungaphezu kwama-USD ayizigidi eziyi-15 ngo-2022.Umugqa wethu wesikhunta se-exothermic kuphela ugijima izingcezu eziyi-10,000 ngenyanga ochungechungeni lwethu lwe-AF-0408, AF-0302 kanye ne-AF-0308.

Amaklayenti ethu osonkontileka empeleni asisebenzisela izinto ezinhlanu: izinombolo zezingxenye zomkhiqizo ezibhekisela ezikhumbeni zokukhiqiza, ukubumba uphawu lwendlu lwe-OEM olunelogo yabo, izitsha ezixubile zesikhunta kanye nama-clamp ahambisanayo kanye nezibambo, kanye namaphakethe emibhalo - ukuhlolwa kwe-CEPRI, ukubhaliswa kwe-ISO 9001:2015, amarekhodi ebhetshi - ahlanganiswe ukuze kuthunyelwe "okulinganayo okuvunyelwe". Emsebenzini wethu wokuthumela kwamanye amazwe ukuvunyelwa okubushelelezi kwabelana ngomkhuba owodwa esiwuqeqesha kuwo wonke amaklayenti manje:umakhi uletha ifayela lobufakazi lokulingana kanye nebhidi, hhayi ngemuva kwencwadi yesicelo.

Impendulo kaNugget: Okulinganayo okuvunyelwayo yilowo omaphepha akhe afika kuqala.Abahloli bethenda bavuma ukulingana ebufakazini, hhayi ngentengo, ngakho-ke sifaka ukuhlolwa kwe-CEPRI, ireferensi yesitifiketi se-ISO kanye nesilinganiso sempilo yesikhunta emvilophini yokuqala - futhi sincoma ukuthi ufune ukusabela okufanayo kunoma yikuphienye indlela yokubumba isikhunta sokushisela esishisayoumhlinzeki omhlolayo. 

Sikumema ukuthi upheqa izigaba ezingemuva kwalesi siqondisi: sethuIzikhunta ezilingana ne-Cadweld ezenziwe eShayina, iintengo yesikhunta kanye nekhasi lokucushwa, kuqediweAmasethi okushisela esitayela se-Cadweld, kanye nokugcweleisigaba sesikhunta sokushisela se-exothermic.

imibuzo ejwayelekile ukubuzwa

Ingabe izikhunta ezilingana ne-Cadweld zisemthethweni ukuzithenga nokuzisebenzisa?

Siphendula ngoyebo. I-Cadweld iwuphawu lwe-nVent ERICO lwenqubo yokushisela i-exothermic, okuyikhemistri engenalo ilungelo lobunikazi eneminyaka eyikhulu. Izikhunta ezilinganayo ziyimikhiqizo esemthethweni; okumele abakhi benkontileka bazihloniphe uphawu lokuhweba (okulingana nemakethe njengokuthi “i-Cadweld-compatible” noma “izikhunta ze-exothermic”, hhayi njenge-Cadweld) kanye nencazelo (sebenzisa okulingana lapho ithenda ivumela “noma kuvunyelwe okulingana”).

Ngingayichaza kanjani isikhunta esilinganayo ukuze sihambisane nabaqhubi bami?

Thumela amaphuzu amane edatha: uhlobo loxhumano (umndeni wesikhunta njenge-GT, GR, TA, SS, XA noma i-VS), sebenzisa usayizi wesikhondisi kanye nezinto, usayizi wesikhondisi sempompi, kanye nobubanzi benduku noma bomphezulu. Ngaphandle kwalokho thumela inombolo yengxenye yomkhiqizo — ifaka amakhodi amanani afanayo amane, bese sibheka ngqo kuyo.

Ingabe izikhunta ezilinganayo zifanelana nezibambo zami zezibambo ezikhona?

Ezimweni eziningi zejiyometri, yebo — isikhunta samabhulokhi amabili esine-clamping yangaphandle siyindlela evamile embonini, kanti uhlaka lwesitayela se-L160 luhlanganisa imindeni yesikhunta evame kakhulu. Siqinisekisa ukuhambisana kwe-clamp ngokubhala ngayo yonke ikhotheshini futhi sinikeze ama-clamp ahambisanayo lapho kudingeka khona.

Ingakanani ngempela isikhunta esilinganayo saseShayina?

Ezicaphunweni zethu zokuthumela kwamanye amazwe, izikhunta ezilingana nefektri zivame ukuba ngaphansi kuka-40-60% kwesilinganiso segama lomkhiqizo, ikakhulukazi ngoba intengo yeqa izendlalelo zokusabalalisa. Ukonga kungokoqobo, kodwa ukuhlola lapho umhlinzeki ekuthola khona: izinga le-graphite kanye nokwakheka kwempuphu yizindawo ezimbili lapho ukonga kubhubhisa khona inani.

Yiziphi izindinganiso okufanele kuhlangatshezwane nazo ukushintshwa kwesikhunta okufanayo?

Sinezilinganiso ezifanayo nezinkomba ezifanayo njengophawu: IEEE 837 yokuxhumeka okuhlala njalo kwesisekelo sesiteshi esincane, IEC 62561-1 yezingxenye zokuxhumeka ezivikela umbani, kanye nohlaka lwe-IEEE Std 80's fault-temperature, olulinganisa ukuxhumeka okuhlanganisiwe kwe-exothermic ku-1,083 °C ngokumelene no-250–350 °C wezixhumi zokucindezela.

Zingaki izingcezu zokushisela okufanele isikhunta esihle se-graphite sihlale isikhathi eside?

Silinganisa izikhunta zethu ngemijikelezo yesevisi engu-50-100; impendulo yethu yasensimini ikhombisa amalunga angu-80-100 ngesikhunta ngasinye ngosayizi wekhatriji ofanele, ukuhlanzwa kwesikhala phakathi kwezithombe kanye nendawo yokugcina eyomile. Umhlinzeki ongafuni ukusho impilo yesikhunta ngokubhala ukutshela okuthile.

Ngingafaka uhlobo lwami lwemikhiqizo ezikhumbeni ezilinganayo?

Sikunikeza — ukukhiqizwa komkhiqizo wendlu we-OEM kuyisevisi ejwayelekile efektri yethu, kufaka phakathi ilogo yakho ku-mold kanye nokupakishwa, uhlelo lwakho lokufaka izinombolo zezingxenye, kanye namaphakethe amadokhumenti alungiselelwe imakethe yakho. Kusebenza okungenani ukugijima ngomndeni ngamunye we-mold; thumela imindeni yakho eqondiwe ukuze uthole isilinganiso sohlelo.

Unayo inombolo yengxenye noma isheduli yomqhubi ukuze ubhekisele kuyo?

Thumela inombolo yengxenye yomkhiqizo — noma amaphuzu amane edatha — bese sizokubuyisela incazelo yesikhunta ehambisanayo enosayizi wekhatriji, ukulingana kwe-clamp yesibambo kanye nentengo yasefektri.
