Ukubuka: 1 Umbhali: Lynn Liu Isikhathi Sokushicilela: 2026-11-03 Umsuka: Isayithi
Izingcaphuno ezimbili zihlala etafuleni elilodwa. Zombili zithi i-DIN 2353, uchungechunge olukhanyayo, ishubhu engu-12 mm, ibha engu-315, i-zinc-nickel. Eyodwa ishibhe ngamaphesenti ayishumi nesishiyagalombili. Umthengi uyakugunyaza, i-athikili yokuqala ilinganisa ukudweba, futhi okokufakwayo kungena emshinini osebenza izinyanga eziyishumi nanye ngaphambi kokuba ilunga elilodwa liqale ukukhala. Akukho okwakubangelwa ukubekezelelana. Inkinga incane futhi inzima ukuphikisana nayo: izinga litshele umphakeli intambo kanye nekhoni engu-24 degree. Ayizange ibatshele ukuthi ekabani indandatho yokusika ingena esikhwameni.
Ngakho nansi impendulo emfushane. Ukufakwa kwe-DIN 2353 kuyashintshana kusixhumi esibonakalayo futhi akukho kwenye indawo. Uchungechunge, i-engeli yekhoni, ishubhu elingaphandle kwedayamitha kanye nobukhulu bochungechunge bulungisiwe, yingakho noma iyiphi imboni enekhono ingenza ingxenye exhuma ekugcineni kweshubhu lakho. Ukuhlangana kuyindaba ehlukile. Indandatho yokusika, i-nati elishayelayo, insimbi ngemuva kwayo kanye namaphepha afakazela inkatho konke kushiywe kumhlinzeki. Leso sikhala yilapho ukuthengwa kwesibili kungalungile, futhi i-oda lokuthenga livala noma likushaya indiva.
Lesi sihloko siphendula imibuzo amathimba ahlonzayo asibekela yona, ngokulandelana aqhamuka ngayo: lokho ukumakwa kuqinisekisa ngempela, noma ungakwazi ukugcina amantongomane namaringi akho akhona, kungani izingcaphuno ezimbili 'ze-metric bulkhead' zingeyona ingxenye efanayo, lapho isilinganiso sokucindezela siyeka ukuqhathaniseka, futhi yini okufanele ihlale ku-RFQ ngaphambi kokuthi umthombo omusha ubale njengokulingana.
Ukumakwa engxenyeni kuyisimangalo sobukhulu, hhayi isimangalo sokusebenza. Uma i-fitting iphethe i-DIN 2353 kanye nochungechunge lwencwadi, umphakeli ukutshela ukuthi ifana nomdwebo. Ilokho kuphela.
Izinga lilungisa uhlu olufushane. I-engeli yekhoni engu-24 degree. Intambo ebhanqa neshubhu ngayinye ububanzi obungaphandle, ngakho-ke i-6 mm ithatha i-M12x1.5, i-8 mm ithatha i-M14x1.5, i-10 mm ithatha i-M16x1.5 futhi i-12 mm ithatha i-M18x1.5 ochungechungeni olukhanyayo. Ubukhulu bochungechunge, ngochungechunge olukhanyayo lulinganiselwe kumabha angu-315 nochungechunge olusindayo kumabha angu-630. Ubukhulu bodonga ishubhu okufanele ithwale.
Ishiya uhlu olude luvuliwe. Ijiyomethri yokusika yeringi, okuhlanganisa ukuthi inonqenqema olulodwa noma amabili, ukuthi ilukhuni kangakanani nokuthi i-lead-in ishaywa kanjani. Iphrofayili yangaphakathi yentongomane ephusha iringi phambili. Ugqinsi lwe-plating ngaphakathi kobubanzi obuvunyelwe. Ibanga lensimbi, njengoba i-C45 carbon steel kanye ne-316L engagqwali kokubili kuyizinketho ezisemthethweni futhi akukhona okuzenzakalelayo. Ukuthi inkatho ihloliwe yini noma ikalwe kuphela. Futhi yiziphi izincwadi ezihamba nebhokisi.
Funda lolo hlu futhi futhi isiphetho asikhululekile. I-DIN 2353 iziphatha njengezinga lechweba elingaphezu kakhulu kwezinga elihlanganyelwe. Izimboni ezimbili zingakuthobela zombili futhi zisathumela amalunga aziphatha ngendlela ehlukile ngemva kwemijikelezo eyinkulungwane yokucindezela.
Cha, hhayi njengomkhuba. Inathi, iringi kanye nomzimba kusebenza njengesistimu eyodwa, futhi izinga lidonsa kuphela imvilophu kuleyo sistimu.
Indandatho yokusika iyisizathu. Ekuhlanganiseni kokuqala iringi iluma phezu kweshubhu kanye nezihlalo zayo zangemuva ngokumelene nekhoni emzimbeni. Leyo isethi yaphakade. Hlukanisa ilunga futhi iringi isivele yakhiwe ngokumelene neshubhu elilodwa nesihlalo esisodwa. Ibeke komunye umzimba futhi kufanele ilume okwesibili. Indandatho esebenze kanzima kanye ayiwusiki umsele ohlanzekile wesibili, futhi uphawu olutholayo luyinhlanhla kunokuklama.
I-nati ibalulekile ngesizathu esifanayo ngakolunye uhlangothi. Inati ithuluzi elakha iringi. Ikhoni yakhona yangaphakathi ishayela ubuso bangemuva beringi phambili ngebanga elibekiwe, kanti umehluko omncane kuleyo phrofayili ushintsha ukuthi iringi ihambe ibanga elingakanani nokuthi ihlale kuphi. Inadi elivela embonini ethile eringini elisuka kwenye liyizingxenye ezimbili zethuluzi lokucindezela elenzelwe imidwebo ehlukene.
Umthetho wokuthola imali olandelayo ulula. Faka inadi, iringi kanye nomzimba ohlelweni lokuthenga njengento eyodwa yomugqa enenombolo eyodwa, hhayi njengemigqa emithathu efika ndawonye. Uma umthombo wesibili kufanele ungene, ulethe njengesethi ephelele futhi ugunyaze kabusha ukuhlanganisa ngeshubhu yakho ngevalu yakho yetorque. Kukhona okuhlukile okukodwa okusemthethweni: uma umzimba kuwukuphela kwengxenye ophelelwe yiyo, umthombo wesibili umzimba uwedwa futhi ugcine amantongomane namaringi angempela, inqobo nje uma isihlalo sekhoni sihlola nge-engeli efanayo nokujula.
Cha, futhi leli iphutha lereferensi esilibona kakhulu. Zombili izingxenye zidlula umugqa ngephaneli. Kokubili ukufakwa kwe-bulkhead. Zombili ziyi-metric. Awenzi umsebenzi ofanayo.
I-6C kulayini we-Ruihua Hardware iyi-metric male 24 degree cone bulkhead ochungechungeni olukhanyayo. Ikunikeza uxhumano lweshubhu nhlangothi zombili zephaneli, futhi zombili iziphetho zivala ikhoni. I-6E iyi-metric male O-ring bulkhead. Ivaleka ngendandatho ye-O ehlala echwebeni elihlanganisiwe. Ukulungiswa kwechweba elihlukile, uphawu oluhlukile, ukubhoboza okuhlukile ngephaneli.
Uma umdwebo wakho ubiza i-cone bulkhead engu-24 degree bese umphakeli omusha ethumela i-O-ring bulkhead ngoba bobabili bahlezi ngaphansi 'kwe-metric bulkhead' kuthebula lereferensi ephambanayo, uthola ingxenye elingana imbobo hhayi isekethe. Izofaka. Ingase ibambe ngisho nengcindezi ephansi. Ichweba efika kulo akulona nje ichweba elakhelwe lona.
Ireferensi yezinkambu ezine, hhayi egameni: intambo, uhlobo lophawu, ishubhu elingaphandle kobubanzi, uchungechunge. Uma umphakeli engakwazi ukugcwalisa zone zengxenye ayinikezayo ngokumelene nenombolo yakho yengxenye, ireferensi ephambene ayiqediwe. Bangakwazi ukubuyekeza uhla olugcwele ku- ikhasi lemikhiqizo.
I-2BC kanye ne-2BD kububanzi be-Ruihua Hardware ama-metric kanye ne-BSP thread studs enophawu oluhlanganisiwe. Zivala ubuso obuyisicaba bembobo ebheke endaweni, zisebenzisa iwasha ye-elastomer evalelwe ngaphansi kwe-hex. Ngosayizi abaningana intambo iyintambo engu-M efanayo ongayithola ku-24 degree cone stud.
Lolo chungechunge olwabiwe luwugibe. Faka i-bond seal stud embotsheni yekhoni futhi ingena kahle futhi izwakala ilungile. Ngeke ivaleke, ngoba iwasha idinga ubuso obunomshini oyisicaba ukuze iphihlizwe, futhi imbobo yekhoni inikeza ikhoni lapho iwasha ilindele ubuso. Okuhlehlayo kufana ncamashi: i-24 degree cone stud embotsheni yotywino enobuso bendawo ayinakho ikhoni yokuhlala, ngakho-ke ukuthintana kwensimbi kuya kwensimbi okwenza ukuvala kungenzeki.
Lolu uhlobo olubiza kakhulu lwengxenye engalungile ngoba ifaka ngaphandle kwesikhalazo. Akukho okuphambene. Akukho okuphuma phambili kusenesikhathi. Ihluleka ngengcindezi, noma emjikelezweni wokushisa wokuqala, noma ebhentshini lokuhlola embonini yekhasimende, okuyindawo embi kakhulu yokuthola. Ungahlola ububanzi be-stud ku- Ikhasi lophawu elihlanganisiwe le-2BC 2BD.
Akunjalo, ngoba ibha engu-315 iyinombolo yochungechunge kunomphumela wokuhlola. Uchungechunge olukhanyayo lulinganiselwe kubha engu-315 nochungechunge olusindayo kubha engu-630, futhi zombili izinombolo zithatha udonga lweshubhu olulungile kanye nelunga elihlanganiswe kahle. Shintsha noma usilingi uyanyakaza.
Izinto ezintathu ziwuhambisa kusekethe wangempela. Ukujiya kodonga lweshubhu kububanzi obufanayo obungaphandle, njengoba udonga oluncane luguquguquka kakhulu ngaphansi kwama-spikes bese lukhulula iringi. Okubalulekile, ngoba i-C45 ne-316L aziphathi ngendlela efanayo ngaphansi kokuhamba ngebhayisikili ngisho noma zombili zihlangana nomdwebo wobukhulu. Futhi umbuso wokuhlola, ngoba okuningi okwahlolwa ubufakazi akuyona into efanayo nenqwaba eyalinganiswa futhi yapakishwa. Uma umbuzo owuchungechunge ngokwawo usavuliwe, indatshana yangaphambili ivuliwe I-DIN 2353 ekhanyayo iqhathaniswa nochungechunge olusindayo idlula lapho okujwayelekile kudonsa lowo mugqa.
Ngakho cela isisekelo, hhayi inombolo. Ingcindezi yokuhlolwa kobufakazi kanye nesilinganiso sesampula inkatho ngayinye, noma umbiko wokuhlolwa kokuqhuma. Ukuze uthole ukuvikelwa kwendawo, cela umbiko kunenkulumo ethi: 8 kuya ku-12 microns we-zinc-nickel enamahora angu-240 wesifutho sikasawoti esimaphakathi ku-ASTM B117 iwuphawu, kuyilapho 'i-zinc nickel' iyodwa iyincazelo kuphela.
Imigqa eyisikhombisa. Zonke zikhona ngoba umthengi ubanjwe ngaphandle kwayo.
Okujwayelekile kanye nochungechunge. Caphula i-DIN 2353 ne-ISO 8434-1 ndawonye, bese uqamba uchungechunge: ukukhanya, i-cone engu-24 degree, indandatho yokusika. Izinombolo ezimbili ezijwayelekile zivimba umphakeli ekukhetheni uchungechunge egameni lakho.
I-tube, hhayi nje ukulingana. Ngaphandle kobubanzi nodonga, isibonelo 12 x 1.5 mm, kanye nempahla kanye nolaka.
Intambo ne-seal, ebhalwe ngokwehlukana. I-M18x1.5 kanye ne-24 degree cone amaqiniso amabili. 'Metric' akuyona enye yazo.
Ukwelashwa kwendawo ngezinombolo. I-Zinc-nickel kuma-microns ayi-8 kuye kwayi-12, amahora angama-240 i-ASTM B117, noma i-zinc engenalutho uma yilokho okushiwo umdwebo.
Amadokhumenti. I-TS EN 10204 3.1 inombolo yokushisa ngayinye, umbiko wobukhulu, kanye nokumaka olindele ukukubona engxenyeni.
Ifomu elethiwe. Inathi, indandatho nomzimba kunikezwa njengesethi eyodwa emeshayo evela kunkatho eyodwa, ingenayo imigqomo exubile ebhokisini.
Isinyathelo sokugunyaza. I-athikili yokuqala ehlanganiswe eshubhuni lakho, ifakwe isikrufu sakho, ingcindezi yajikeleza, yavalwa ngaphambi kokuthi kukhishwe i-oda lokuthenga.
Umugqa wesikhombisa yiwona oyehliswayo uma umsebenzi wephuzile. Futhi iwukuphela komugqa ohlola ilunga kunomdwebo.
Akuvamile ku-invoyisi, futhi ngokuvamile endaweni ethile lapho kusebenza. Izindawo ezine ongazibheka ngaphambi kokuthi usayine.
Izitifiketi zikhokhiswa inkatho ngayinye. Isitifiketi esingu-3.1 sifaka inombolo yokushisa, hhayi ucezu. Hlanganisa osayizi abayishumi nambili endaweni eyodwa yokukhiqiza futhi izindleko zesitifiketi zisabalele kulo lonke uhlelo. Hlukanisa i-oda elifanayo ube ama-oda okuthenga ayishumi nambili futhi uthenga amalotho ayishumi nambili, imijikelezo yokuhlola eyishumi nambili kanye namasethi ayishumi nambili wamaphepha, okuvamise ukuba lapho amaphesenti ayishumi nesishiyagalombili aye khona.
Inani elincane le-oda ngosayizi ngamunye, hhayi nge-oda ngalinye. I-oda elinosayizi abayishumi nambili ngobuncane bosayizi ngamunye ukuzibophezela kosayizi abayishumi nambili. Buza ukuthi ubuncane bubalwa ngayiphi indlela ngaphambi kokuqhathanisa inani eliphelele.
Isikhathi sokuhola ngokumelene nesitobhi somugqa. Osayizi besitoko namasayizi enziwe ukuze a-odwe yimikhiqizo ehlukene ngamanani ahlukene. Ikhotheshini eshibhile ekuholeni kwamasonto ayisithupha ayishibhile uma umshini ulindile, futhi i-delta kulula ukuyibala uma sewazi izindleko zakho zokuphumula ngosuku.
Sebenza kabusha kanye nezimangalo. Ijoyinti elilodwa lokukhala emshinini ogunyaziwe libiza ngaphezu kwegebe lentengo uma ugijima ngokugcwele: uwoyela okhishiwe, ishubhu elisha, iringi entsha, ukufinyelela kwe-crane kanye nosuku lwabasebenzi. Futhi ngaphandle kokumaka inkatho nesitifiketi esingu-3.1 awukwazi ukulandelela inqwaba embi emuva enombolweni yokushisa, ngakho udonsa yonke inkatho esikhundleni sokuncibilika okukodwa.
Kwa-Ruihua Hardware, okulethwayo kuyisethi efanisiwe kunesikhwama sezingxenye. Amantongomane, indandatho yokusika nomzimba kukhiqizwa futhi kupakishwe njengesistimu eyodwa ngosayizi ngamunye, ngamakepisi okuvikela intambo, bese kuba yikhathoni kanye nephalethi. Zonke izingcezu ziyahlolwa ngaphambi kokuthi zihambe, futhi osayizi abajwayelekile bacashunwa ezinsukwini eziyi-7 kuye kweziyi-15.
Insimbi iyi-C45 carbon steel njengejwayelekile, kanti i-316L itholakala lapho isekethe noma iwashdown ikufuna. I-Surface iyi-zinc-nickel kuma-microns angu-8 kuya kwangu-12, aqinisekiswa amahora angu-240 e-ASTM B117, noma i-zinc engenalutho yomsebenzi wangaphakathi. Izingxenye zochungechunge olusindayo zivivinywa ngaphambi kokuthunyelwa. Ukumaka engxenyeni kuthwala uchungechunge nosayizi, ngakho umgcini wesitolo angakwazi ukuhlukanisa umzimba olula kosindayo ngaphandle kwe-caliper.
I-O-ring bulkhead engenhla iyisibonelo esihle sokuthi kungani ukupakisha kubalulekile. Ungabona imininingwane ku- Ikhasi le-bulkhead ye-6E O-ring , kufaka phakathi i-cap yokuvikela intambo, engewona umhlobiso. Intambo egobile ku-bulkhead stud iyingxenye enqatshiwe ekungeneni kwezimpahla, futhi leyo mpikiswano ibiza ngaphezu kwekepisi.
Emzimbeni ofanayo kuphela futhi endaweni efanayo, iqiniswe kunani elifanayo. Indandatho efakwe i-torque ilume ishubhu futhi yahlala phezu kwekhoni, ngakho-ke ithathe isethi. Iyise komunye umzimba futhi kufanele isike umsele wesibili, okuyinto indandatho eqinile yokusebenza engayenzi ngokuhlanzekile. Phatha iringi njengento esebenzisekayo futhi intengo ngaleyo ndlela.
Cha. Amasekhethi angaphakathi kuphakethe lamandla angaguquki ngokuvamile amukela isimemezelo esingu-2.2 kanye nombiko wobukhulu. Amakhasimende okugcina aseYurophu, umsebenzi wasolwandle kanye nemisebenzi yokuphepha kufanele aphathe i-3.1 ngokushisa ngakunye. Nquma iphrojekthi ngayinye futhi uyibeke ku-RFQ, ngoba ukuyengeza ngemva kwe-oda kusho into entsha nesikhathi sokuhola esisha.
Yebo, nge-adaptha, kodwa usungaba ngumnikazi wamalunga amabili esikhundleni selilodwa. I-adaptha kufanele ihambisane ne-DIN 2353 ngakolunye uhlangothi kanye nochungechunge lwe-G olunophawu olulungile ngakolunye. Ijoyinti ngalinye linenani lalo le-torque kanye nendlela yalo yokuvuza, futhi umhlangano ukhula isikhathi eside, okuvame ukuba yisizathu sangempela sokuthi i-adaptha ingakwazi ukungena.
Izinkambu ezinhlanu: ezijwayelekile kanye nochungechunge, ishubhu elingaphandle kobubanzi nodonga, intambo kanye nohlobo lophawu, impahla nengaphezulu, kanye nemibhalo edingekayo. Ngalezo ezinhlanu, izingcaphuno ezimbili zichaza ingxenye efanayo. Ngaphandle kwabo, uqhathanisa izingxenye ezimbili ezihlukene ngamanani amabili.
Kungaba, uma lonke ukujoyina kugunyazwe njengesethi. Umzimba, amantongomane nendandatho evela kumnikezeli ofanayo, kuhlanganiswe kushubhu yakho ngevelu yetorque yakho, futhi kuhlanganiswe ukuhlolwa kobufakazi noma umbiko wokuhlola. Ukuxuba amabhrendi ngaphakathi kwelunga elilodwa inhlanganisela ehlulekayo.
Thumela izinto ezinhlanu: uchungechunge, ishubhu elingaphandle kobubanzi nodonga, uhlobo lwentambo nophawu, imfuneko yendawo enezinombolo, kanye nemibhalo oyidingayo. Zithumele ku-Ruihua Hardware ngokusebenzisa i- ikhasi lokuxhumana futhi impendulo ibuya nochungechunge, isisekelo sokuhlola kanye nesikhathi sokuhola esibhaliwe, ukuze ukwazi ukubeka izingcaphuno ezimbili eceleni futhi ubone ukuthi igebe lingokoqobo yini. Uma umdwebo umdala futhi uchungechunge lungacacile, yisho kanjalo. Umbuzo obuzwe ngaphambi kwe-oda ushibhile kunejoyinti elikhala ngemuva kokuthunywa.
