Uma ngithumela iqembu leizihlanganisi zenduku ezinentamboKusukela efektri yethu eXinchang, umbuzo owodwa engiwuzwa kakhulu konjiniyela bokuthenga uthi: “Ngingazi kanjani ukuthi intambo izongena ngempela uma ifika endaweni?” Kuyinkinga efanele. Induku yomhlabathi engenakuxhunywa ensimini akuyona nje inkinga - kungukwehluleka kwesistimu yomhlabathi okulinde ukwenzeka. Kulesi sihloko, ngidlula ezindinganisweni zentambo, ukuhlolwa kokubekezelelana, kanye nezinyathelo zokugunyazwa zesampula esizisebenzisa ngaphakathi futhi engincoma ukuthi wonke umthengi aziqinisekise ngaphambi kokusayina i-oda lokuqala.

Kungani Ikhwalithi Yentambo Entongeni Engaphansi Kungeyona Imininingwane Encane

Ngokwami, i-electrode yokumisa inhlabathi isebenza kuphela kanye nejoyinti layo elibuthakathaka kakhulu. Esikhungweni sethu sokukhiqiza, sibone amasampula abuyiselwe lapho uqweqwe lwethusi lwalungenasici emzimbeni wenduku kodwa intambo yokuxhuma yayisusiwe ngesikhathi sokuthutha ngoba ukubekezelelana kwakulula kusukela ekuqaleni. Ithimba lethu le-QA lidlulise induku ekuhlolweni okubonakalayo echwebeni lokulayisha, kodwa yehluleka ensimini ngesikhathi sokufakwa kogwini eNtshonalanga Afrika lapho unkontileka wayeshayela khona induku enhlabathini ye-laterite ngaphansi kwesikhathi esinzima.

Ngenxa yokuthi intambo iyibhuloho elisebenza ngomshini nelikagesi phakathi kwezingxenye ezimbili zenduku, intambo enqunywe kabi noma engafakwanga kahle iba yindawo yokumelana okuphezulu kuyo yonke indlela yokumisa umhlaba. Lokho kumelana kubalulekile ngesikhathi somcimbi wombani lapho amashumi ezinkulungwane zama-ampere kudingeka ahlakazeke emhlabeni ngemizuzwana emincane.

Uma sikhiqizaizinduku zensimbi ezimbozwe ngethusi, intambo iyasikwa noma igoqwe ngemva kwesinyathelo sokusonga ithusi. Inqubo yethu iqinisekisa ukuthi lolu chungechunge luvikela ubuso obumboziwe ngesikhathi sokwakheka, kodwa futhi kusho ukuthi noma yiliphi iphutha elilinganayo entanjeni libonakala ngqo kumkhiqizo oqediwe. Akukho ungqimba lwe-buffer olufihliwe lokufihla inkinga.

Izindinganiso Zomcu Ozohlangana Nazo Ekuthengeni Okuyisisekelo

Eminyakeni yami eyishumi nambili yokuthumela imikhiqizo yokumisa umhlabathi evela efektri yethu, ngisebenze nabathengi emazweni angaphezu kwamashumi amane. Amafomu entambo avela kakhulu kumadokhumenti e-RFQ ezinduku zomhlaba kanye nama-coupling awela emikhayeni emine:

I-Unified National Coarse (UNC) — Okuzenzakalelayo KwaseNyakatho Melika

Izintambo ze-UNC, ezilawulwa yi-ASME B1.1, zibusa izimakethe zase-US, eCanada, naseMexico. Ngezintambo ezisetshenziswa emhlabathini, osayizi abavame kakhulu yi-5/8″-11 UNC kanye ne-3/4″-10 UNC. I-“11″ kanye ne-“10″ zibhekisela kuzintambo nge-intshi (TPI). Induku ye-UNC engu-5/8″-11 inobubanzi obukhulu obungu-15.875 mm kanye nephimbo elingu-2.309 mm. Sikhiqiza lo sayizi ngobuningi obukhulu kumakhasimende afaka amagridi okusekela phansi eziteshini ezincane kanye nezisekelo zombhoshongo wezokuxhumana kulo lonke elaseNingizimu ye-United States.

Sake sahlinzeka ngepulazi lelanga enkabeni yeTexas elinama-couplers angu-5/8″-11 e-UNC ezinduku zomhlabathi ezimbozwe ngethusi ezidonswa zijule ngamamitha amathathu enhlabathini yobumba. Umfakisi ubike ukuhlanganiswa okubushelelezi kulo lonke ibhetshi ngoba sasiqinisekisile ububanzi bephimbo ku-14.705 mm (ngaphakathi kwebhendi yokubekezelelana ye-2A) entongeni ngayinye yeshumi ngesikhathi sokukhiqiza.

Inhlawulo Kazwelonke Ehlanganisiwe (UNF) — Engavamile Kancane Kodwa Isacacisiwe

Ngokwalokho esikubonile, imicu ye-UNF ivela kwezinye izincazelo ezithonywe yiYurophu kanye nasezinhlelweni zokusebenza lapho iphimbo elincane likhethwa khona ukuze kuvinjwe ukudlidliza. I-coupling engu-5/8″-18 UNF inobubanzi obukhulu obufanayo nobayo be-UNC kodwa cishe iphindwe kabili kune-TPI. Iphimbo elincane lisho ukubandakanyeka okwengeziwe nge-millimeter ngayinye yobude be-axial, okuzuzisayo enhlabathini enamadwala lapho amandla okushayela ephezulu khona. Kodwa-ke, imicu ye-UNF isheshe ithinteke kakhulu ekuthungeni okuwelanayo ngesikhathi sokuhlanganiswa kwensimu, ngakho-ke ngeluleka abathengi abacacisa i-UNF ukuthi nabo bacele i-chamfered lead-in ekugcineni kwesilisa kwe-coupling.

Ipayipi Elijwayelekile LaseBrithani (BSP) — Lisakazeke Kakhulu eMpumalanga Ephakathi nase-Afrika

Imicu ye-BSP, ikakhulukazi uchungechunge lwe-G (parallel) oluchazwe ku-ISO 228, ivame kakhulu ezinhlotsheni ezivela emazweni aseGulf, eNigeria, eKenya, naseNingizimu Afrika. Ukuhlanganiswa kwe-G1/2 noma kwe-G3/4 akunciphisi - kuncike ekufaneni okuhambisanayo. Lokhu kwenza ukuqinisekiswa kobukhulu kube yinto ebaluleke kakhulu ngoba akukho senzo sokubopha ukuze kulungiswe usayizi omncane. Ngokwesipiliyoni sethu sokunikezainduku yomhlabathi kanye nenduku yomhlabathiimikhiqizo kumaphrojekthi aseDubai naseLagos, ama-BSP couplers adlula ukuhlolwa kwe-ring gauge esiteshini sethu se-QC asebenza ngokwethembeka enhlabathini enesihlabathi, enokumelana okuphezulu.

Imicu ye-Metric ISO (Uchungechunge lwe-M) — I-Global Standard

Izintambo ze-metric ngokwe-ISO 261 kanye ne-ISO 965 ziyizinto ezizenzakalelayo ezwekazini laseYurophu, ingxenye enkulu ye-Asia, i-Australia, kanye nezingxenye zaseNingizimu Melika. Ngezinduku zokumisa, i-M16 kanye ne-M20 yizo ezivamile. I-M16x2.0 coupling inobubanzi obukhulu obuyi-16 mm kanye ne-pitch engu-2.0 mm. Isigaba sokubekezelelana esijwayelekile singu-6g (ngaphandle) / 6H (ngaphakathi). Ngenxa yokuthi izintambo ze-metric zichazwe ezindinganisweni ze-ISO ezithathwe yizinhlangano eziningi zezwe, isampula edlula i-ring gauge engu-6g ngokuvamile izokwanelisa abahloli kungakhathaliseki ukuthi iphrojekthi ikuliphi izwe. Sigcina ama-couplers anezintambo ze-metric ethuizinduku zomhlabathi zensimbi ezifakwe i-galvanizedkanye neyethuizinduku ezicwengekile zethusingobukhulu obungu-M12 kuya ku-M24.

Ukubekezelelana Nokulingana Kwemicu: Okushiwo Yizinombolo Ekuzijwayezeni

Ukubekezelelana kwentambo kusitshela ukuthi izingxenye ezimbili zizohlanganiswa ngesandla, nge-wrench, noma cha nhlobo. Nasi ithebula lokubhekisela lezindinganiso zentambo yenduku yomhlabathi ozohlangana nazo:

Embonini yethu, sisebenzisa ama-ring gauge nama-plug gauge alinganiswe nalawa ma-tolerance band kuyo yonke inqubo yokukhiqiza. Kumthengi obuyekeza isampula, iseluleko esiwusizo kakhulu engingasinikeza ngokusekelwe eminyakeni yami kulo mkhakha: Ngihlala ngiphatha i-mating coupler noma i-gauge eyaziwayo ekuhlolweni kwesampula. Ukuhlola ukuhamba/ukungahambi kuthatha ngaphansi kwemizuzwana eyishumi ngenduku ngayinye futhi kubamba ukuzulazula kobukhulu okungase kuphuthelwe yisilinganiso se-caliper sodwa.

Amaphutha Emicu Evamile Nendlela Yokuwabona

Eminyakeni edlule efektri yethu, ngibhale uhlu lwamaphutha abangela izikhalazo zasensimini kaningi. Nakhu ithimba lethu le-QC kanye nabahloli bamakhasimende ethu abakubhekile — nalokho engikuncoma ukuthi ukuhlole ngesikhathi sokubuyekezwa kwakho okulandelayo kwesampula:

• Umonakalo wokusonta: Kwenzeka lapho izintambo zesilisa nezesifazane zingalingani ngaphambi kokuqina. Izintambo zokuqala ezimbili kuya kwezintathu zibonisa ukuguquguquka. Kusampula, lokhu kuziveza njengokuzizwa okuqinile lapho siphendula ngesandla i-coupling. Sikuqeda lokhu ekukhiqizeni ngokuchoboza ukungena kwentambo yesilisa kuma-degrees angu-30.
• Ubukhulu obukhulu be-diameter: I-thread crest edlula umkhawulo ophezulu we-tolerance band ngeke ingene kwi-coupler. Lokhu kwenzeka kaningi ezindongeni lapho ukugoqa intambo kwenziwa khona ngemva kokufakwa kwe-copper coating kanye ne-coating enezela ukujiya okungalindelekile. Silawula lokhu ngokuqapha isisindo se-coating ngendawo ngayinye ngaphambi kwesinyathelo sokufaka i-thread.
• Ububanzi bephimbo elingaphansi kosayizi: Ukulingana okuxegayo okuvumela ukuhlanganiswa ukuthi kuxegaxeke. Nakuba kungase kubonakale kulula ngesikhathi sokuhlanganiswa, intambo exegayo isho indawo yokuxhumana encishisiwe kanye nokumelana kukagesi okuphezulu ejoyintini. Onjiniyela bethu babeka ama-rolling dies ukuze aqondise phakathi kwebhendi yokubekezelelana, hhayi umkhawulo ophansi.
• Ama-burrs ezimpandeni zentambo: Ama-burrs abukhali ashiywe yithuluzi lokusika elibuthakathaka noma idayisi eligugile lokugoqa. Angasika intambo yokuhlangana ngesikhathi sokuhlanganiswa futhi adala amaphuzu okugxila ekucindezelekeni asheshisa ukukhathala ngaphansi kokujikeleza okuphindaphindiwe kokushisa. Ukuhlolwa okusheshayo kwensimu ithimba lethu elikusebenzisayo: sebenzisa indwangu yekotini eceleni kwentambo - uma ama-fiber ebamba, ama-burrs akhona.
• Ukugoba ngentambo: Ukwemboza ngethusi noma nge-zinc okukhuhla intambo ngesikhathi sokwakheka. Lokhu kuveza insimbi eyisisekelo ekugqwaleni, okwandisa ukumelana kwamalunga ngokuhamba kwesikhathi. Sihlola ukunamathela ngenqubo yokugoba nokukhuhla kuyo yonke inqwaba.

Uhlu Lokuhlola Lokuvunyelwa Kwesampula: Iphrothokholi Yangaphakathi Yefektri Yethu

Uma omunye wamakhasimende ethu ecela isampula yangaphambi kokukhiqizwa kwemikhiqizo yethuIzixhumi zenduku yomhlaba ezinentambo eziyi-14.2mmnoma yimuphi omunye umkhiqizo wokumisa ngentambo, sibheka uhlu lokuhlola olunamaphuzu ayishumi nambili. Ngabelana ngengxenye ethile yentambo lapha ngoba yisigaba abathengi abaningi abasibuza ngaso:

1. Ukuqinisekiswa kwefomu lentambo: Qinisekisa i-engeli yentambo (ama-degree angu-60 e-UNC/UNF/metric, ama-degree angu-55 e-BSP) usebenzisa i-optical comparator noma i-thread gauge.
2. Ukulinganiswa kwephimbo: Sebenzisa igeyiji yephimbo lentambo ukuqinisekisa ukuthi iphimbo le-TPI noma le-mm lihambisana nencazelo. Ku-5/8″-11 UNC, i-intshi ngayinye yobude bephimbo kufanele ibonise imicu engu-11 egcwele.
3. Ububanzi obukhulu: Kala nge-micrometer ezindaweni ezimbili eziqhelelene ngama-degree angu-90. Zombili lezi zibalo kumele zibe ngaphakathi kwebhendi yokubekezelelana yekilasi elichaziwe.
4. Ububanzi bephimbo: Sebenzisa i-micrometer yentambo noma indlela yezintambo ezintathu. Lesi yisibonakaliso esibucayi kakhulu sekhwalithi yentambo.
5. Ukuhlolwa kwe-Go/no-go gauge: I-go gauge kumele idlule ngokukhululeka; i-no-go gauge akumele idlule ukujika okungaphezu kwamabili. Lokhu kuhlolwa okukodwa kuthinta iningi lezinkinga zobukhulu.
6. Ukuhlolwa kokulingana kokuxhuma: Hlanganisa induku yesampula ngesandla nge-coupler yokuhlanganisa. I-joint kufanele ihlale ngokugcwele ngamandla aqinile njengomunwe kanye nokujika okungadluli okukodwa nengxenye ngesikrufu.
7. Ukuhlolwa okubonakalayo nokuthintayo: Hlola ama-burrs, amaphutha okufaka i-plating, kanye nokungalungi kobuso. Abahloli bethu bafaka uzipho emnweni wentambo — kufanele luzizwe lubushelelezi futhi lufana.
8. Ukuhlolwa kwe-torque: Sebenzisa i-torque yokuhlanganisa ecacisiwe (ekukhiqizweni kwethu, sicacisa i-40-60 Nm yokuxhumanisa induku yomhlaba engu-5/8″-11 UNC) bese siqinisekisa ukuthi ama-joint holds awasuswanga.

Emgqeni wethu wokukhiqiza, sithatha izithombe zokufundwa kwesilinganiso seqoqo ngalinye lesampula futhi sifaka izithombe embikweni wokuhlola othunyelwa nesampula. Lokhu kucaca kube ngesinye sezizathu ezenza amakhasimende ethu emikhakheni yezokuxhumana kanye nezinsizakalo aqhubeke nokucacisa ukuthiizinduku zomhlabathi ezinentambo zokuhlanganisa.

Izinto Ezibalulekile: Indlela Insimbi Eyisisekelo Ethinta Ngayo Ukusebenza Kwentambo

Intambo ithembeke kuphela njengendwangu esikiwe kuyo. Nansi indlela izinto ezintathu zenduku yomhlabathi esisebenza ngazo ezisebenza ngayo kule ntambo:

Insimbi Embozwe Ngethusi

Iningi levolumu yethu lingena kuizinduku zomhlabathi ezimbozwe ngethusi. Ingqimba yethusi (ngokuvamile engu-0.254 mm noma okungenani engu-0.508 mm) inikeza ukumelana nokugqwala kanye nokuqhuba, kuyilapho ingaphakathi lensimbi linikeza amandla okushayela. Sifaka izintambo zethu ngemva kokuzibeka sisebenzisa ama-rolling dies anezinti ze-carbide acindezela esikhundleni sokusika ithusi, sigcine ungqimba luqhubeka. Seluleka abathengi ukuthi bahlole ukuthi ithusi liyabonakala futhi aliphukile esiqongweni sentambo - insimbi engenalutho izogqwala, esikubonile ekuhlolweni kwensimu enhlabathini phakathi nezinyanga.

Insimbi Ehlanganisiwe Eshisayo

Okwethuizinduku zokumisa ezishisayo ezifakwe ngogesisebenzisaInduku yomhlaba ehlanganisiwe yensimbi engu-Q235ukwakhiwa. Isembozo se-zinc sisebenza okungenani ama-micron angu-50-80 nge-ISO 1461, sisetshenziswa ngokucwilisa induku esiqediwe ku-zinc encibilikisiwe. Ekukhiqizweni kwethu, intambo iyasikwa ngemva kokufaka i-galvanizing, okuveza insimbi engenalutho esiqongweni. Lokhu kuyamukeleka uma i-coupler nayo i-galvanised futhi i-joint ivaliwe. Siphinde sinikezeinduku yomhlabathi eqiniswe nge-galvanizedimikhiqizo enezinketho zokufaka intambo ezifakwe i-galvanized.

Insimbi engagqwali

Ngezindawo ezinokugqwala okuphezulu — ukufakwa kogu, izitshalo zamakhemikhali, noma inhlabathi enokuqukethwe okuphezulu kwe-chloride — sinikezelaizinduku zensimbi engagqwali ezinentambongamamaki angu-304 kanye no-316. I-Austenitic stainless work-iyenza lukhuni ngesikhathi sokugoqa, okungacindezela ububanzi bephimbo ngaphandle kokubekezelelana. Ithimba lethu lobunjiniyela livumelana nenqubo yokugoqa enamaphasi amabili kanye nokulinganisa phakathi kwamaphasi.

Iziqondiso Zokufakwa Kwensimu Zezinduku Zokuxhuma Ezinemicu

Ngisho nenduku ehlanganiswe kahle ingahluleka ensimini uma umfakisi engalandeli inqubo efanele. Ngokusekelwe kwimpendulo evela kumakhasimende ethu kanye nokuvakashela kwami ​​​​isayithi, nansi imikhuba ehlobene nokusebenza okuthembekile kwesikhathi eside:

• Hlanza izintambo ngaphambi kokuhlanganiswa. Inhlabathi, ukungcola, kanye nokungcola kokupakisha entanjeni kuzovimbela ukuhlangana ngokuphelele futhi kungalimaza isiqongo sentambo. Ibhulashi eliqinile kanye ne-wipe ngendwangu ehlanzekile kuthatha imizuzwana engamashumi amathathu futhi kuvimbele amahora okuxazulula izinkinga.
• Qondanisa ngaphambi kokuqinisa. Qala ukuhlanganisa ngesandla, ujikeleze induku ngokwewashi ngokucindezela okuthambile kwe-axial. Uma induku ingaphenduki ngokukhululeka ekuphendukeni kokuqala okubili okugcwele, siyahlehla bese siphinda siqondanise. Ukuphoqa intambo engaqondile kuzoyihlubula.
• Sebenzisa i-anti-oxidation compound ezingosini ezimbozwe ngethusi. Sifaka ungqimba oluncane lwe-anti-oxidation paste ehambisana nethusi entanjeni ngaphambi kokuhlanganiswa ukuze sigcwalise ama-micro-voids futhi sivimbele ukungena komswakama okuholela ekugqwaleni kwe-galvanic engosini.
• Shayela ngesando sokushayisana, hhayi isando sokushelela. Ukushaya okuphindaphindiwe okuvela kusesando sokushelela kudala izikhathi zokugoba endaweni yokuxhumanisa engaqhekeza intambo ehlanganisiwe. Isando esishayela ngenduku yomhlabathi sinikeza amandla aqondile e-axial.
• Qinisekisa ukumelana nomhlabathi ngemva kokufakwa. Sebenzisa isihloli sokumelana nomhlabathi (indlela yokuwa kwamandla ngakunyeIEEE 81) ukuqinisekisa ukuthi induku efakiwe ihlangabezana nokumelana komklamo. Ukwanda okungazelelwe kokumelana uma kuqhathaniswa nenduku enesigaba esisodwa kungabonisa ukuthi intambo ayisebenzi kahle.

Iklayenti lethu enyakatho yeKhanada lisebenzise i-sectionalamasethi enduku yokubumbange-UNC couplings ukuze ifinyelele amamitha angu-18 nge-permafrost. Ngokulandela inqubo yokuqondanisa engenhla, abasebenzi baxhuma futhi bashayela izingxenye eziyishumi nambili ezingamamitha angu-1.5 ngaphandle kokwehluleka kwentambo eyodwa futhi baphumelela ukuhlolwa kokwamukelwa kwenkampani esebenzela okokuqala.

Indima Yezindinganiso Zemicu Ekuhambisaneni Nezinga Lesistimu

Ngokombono wethu, izinhlelo zokusekela phansi azikho zodwa. Ziyingxenye yesimiso esijwayelekileukuvikelwa kombani kanye nokufakwa phansi kukagesiukufakwa okumele kuhlangabezane namakhodi kazwelonke nawamazwe ngamazwe. Izinga lentambo ku-ground rod coupler yakho lingase libonakale liyinto encane, kodwa lixhumanisa nohlaka olukhulu lokuthobela imithetho ngezindlela abahloli bezimali nabahloli bomshuwalense abazihlolayo:

• I-IEEE 80 (ukufakwa kwesisekelo se-AC) — idinga ukuqhubeka kukagesi okuqhubekayo. Ukubekezelelana kwangaphandle kwamalunga kungase kube nokumelana okuphula lokhu. Inkomba:IEEE 80.
• I-UL 467 (Imishini yokusekela nokubopha) — I-UL ihlola ama-electrode okusekela ukuze ithole amandla okusebenza, ukuhanjiswa kwamandla, kanye nokumelana nokugqwala. I-coupler ehluleka ukuhlolwa kwe-UL 467 ngeke ithole uhlu. Ireferensi:UL.
• I-IEC 62561 (Izingxenye zesistimu yokuvikela umbani) — ihlanganisa izixhumi, ama-conductor, kanye nama-electrode omhlaba. Ingxenye 7 ikhuluma ngqo ngokufaka umhlaba. Ama-couplers anezintambo kumele aphumelele ukuhlolwa kwemishini kanye nogesi kule nqubo yokufakwa kwe-LPS.
• Amakhodi kagesi kazwelonke (NEC, BS 7671, AS/NZS 3000) — amakhodi amaningi adinga izingxenye zokusekela ezisohlwini. Isixhumi esingafakwanga ohlwini singabangela ukuthi ukufakwa kungaphumeleli ekuhlolweni.

Emsebenzini wami namakhasimende aphesheya kwezilwandle, ngisize abaningana abathole izinduku zomhlabathi kubaphakeli abangazange baqinisekise amazinga entambo, kodwa ngesikhathi sokuhlolwa kwezimali bathole ukuthi abaxhumanisi abazange bahlangabezane nencazelo. Ukuphazamiseka kokuhlolwa kabusha nokuthengwa kabusha kudlule kakhulu isikhathi esithathwayo ukuqinisekisa ukubekezelelana kwentambo esigabeni sesampula. Ngenxa yokuthi ukwehluleka kokuthobela imithetho kwehla kancane kancane ohlelweni lwephrojekthi, ukuthola intambo efanele kusampula yokuqala kungenye yezenzo ezinenzuzo ephezulu unjiniyela wokuthenga angazithatha.

Indlela Esisekela Ngayo Amaklayenti Ngenqubo Yokuvunyelwa Kwesampula

Uma ucela isampula esikhungweni sethu sokukhiqiza — kungakhathaliseki ukuthiinduku yomhlaba yensimbi eboshwe ngethusi, ukuhlanganiswa okuhlanganisiwe okuhlanganisiwe, nomainduku yensimbi engagqwali enentambo— nansi into esiyinikezayo:

• Umbiko wokuhlola olinganiselayo onezilinganiso zentambo ezithathwe ngamaphuzu amathathu ngobude bokuxhumanisa.
• Izithombe eziseduze zesimo sentambo ekukhulisweni okungu-10x ezibonisa isimo se-crest kanye nokuqhubeka kwe-plate.
• Izitifiketi zokuhlola izinto eziqinisekisa izinga lensimbi eyisisekelo (ngokuvamile i-Q235 noma okulingana nayo nge-GB/T 700), uhlobo lokumboza, kanye nobukhulu bokumboza.
• Ividiyo yokuhlola ukulingana kokuxhumanisa ekhombisa ukuhlanganiswa kwesandla kanye nokusetshenziswa kwe-torque kusampula yangempela.
