Ukusebenza kwesistimu yoketshezi lwezimboni kuncike ekusebenzisaneni kwengxenye ngayinye eletha uketshezi lwenqubo yakho lapho iya khona. Ukuphepha nokukhiqiza kwesitshalo sakho kuncike ekuxhumekeni kwamahhala okuvuzayo phakathi kwezingxenye. Ukuhlonza ukufaneleka kwesistimu yakho yoketshezi, qala uqonde futhi ukhombe usayizi wentambo nephimbo.

Ngisho nochwepheshe abanolwazi ngezinye izikhathi bakuthola kunzima ukuhlonza imicu. Kubalulekile ukuqonda uchungechunge olujwayelekile kanye nemigomo yokunqanyulwa kanye namazinga ukuze usize ukuhlukanisa imicu ethile.
Uhlobo lochungechunge: Intambo yangaphandle kanye nentambo yangaphakathi ibhekisela endaweni yentambo ekuhlanganyeleni. Intambo yangaphandle iphumela ngaphandle kwelunga, kuyilapho intambo yangaphakathi ingaphakathi kwelunga. Uchungechunge lwangaphandle lufakwa ochungechungeni lwangaphakathi.
Iphimbo: iphimbo ibanga eliphakathi kwemicu. Ukuhlonza iphimbo kuncike kumazinga athile ochungechunge, njenge-NPT, ISO, BSPT, njll. Iphimbo lingavezwa ngemicu iyintshi ngayinye kanye ne-mm.
Isengezo kanye ne-dedendum: kuneziqongo nezigodi entanjeni, ezibizwa ngokuthi i-adendum kanye ne-dedendum ngokulandelanayo. Indawo eyisicaba phakathi kwesihloko nempande ibizwa ngokuthi i-flank.
Khomba uhlobo lochungechunge
Isinyathelo sokuqala sokuhlonza usayizi wentambo kanye nezwi ukuthi ube namathuluzi afanele, okuhlanganisa i-vernier caliper, i-pitch gauge kanye negayidi yokuhlonza iphimbo. Zisebenzise ukuze unqume ukuthi intambo i-tapered noma iqondile. i-tapered-thread-vs-straight-thread-diagram
Intambo eqondile (ebuye ibizwe ngokuthi intambo ehambisanayo noma intambo yomshini) ayisetshenziselwa ukuvala, kodwa isetshenziselwa ukulungisa inathi emzimbeni wesixhumi se-casing. Kumelwe bathembele kwezinye izici ukuze benze izimpawu zokuvuza, njengeama-gaskets, ama-O-rings, noma i-metal to metal contact.
Imicu ecijile (eyaziwa nangokuthi imicu eguquguqukayo) ingavalwa lapho izinhlangothi zezinyo zezintambo zangaphandle nezangaphakathi zidwetshwa ndawonye. Kuyadingeka ukusebenzisa i-thread sealant noma i-thread tape ukuze ugcwalise igebe phakathi kwethiphu lezinyo kanye nezimpande zamazinyo ukuvimbela ukuvuza koketshezi lwesistimu endaweni ehlangene.
Intambo ye-taper ise-engeli emgqeni ophakathi, kuyilapho intambo ehambisanayo ihambisana nomugqa ophakathi. Sebenzisa i-vernier caliper ukuze ulinganise ithiphu ukuze uthiphu ububanzi bentambo yangaphandle noma intambo yangaphakathi kuchungechunge olugcwele lokuqala, lwesine nolokugcina. Uma ububanzi bukhula ekugcineni kowesilisa noma kuncipha ekugcineni kowesifazane, intambo iyancipha. Uma wonke ama-diameter afana, intambo iqondile.
Ukulinganisa ububanzi bentambo
Ngemva kokubona ukuthi usebenzisa izintambo eziqondile noma ezicijile, isinyathelo esilandelayo ukunquma ububanzi bomucu. Futhi, sebenzisa i-vernier caliper ukukala intambo yangaphandle yegama noma ububanzi bentambo yangaphakathi ukusuka phezulu kwezinyo ukuya phezulu kwezinyo. Ukuze uthole imicu eqondile, kala noma yimuphi uchungechunge olugcwele. Ngemicu ecijile, linganisa umucu ogcwele wesine noma wesihlanu.
Izilinganiso zobubanzi ezitholiwe zingase zehluke kumasayizi avamile emicu enikeziwe esohlwini. Lolu shintsho lubangelwa ukubekezelelana okuyingqayizivele kwezimboni noma zokukhiqiza. Sebenzisa inkomba yokuhlonza intambo yomkhiqizi ukuze unqume ukuthi ububanzi busondele kusayizi olungile ngangokunokwenzeka. intambo-pitch-gauge-measurement-diagram
Nquma iphimbo
Isinyathelo esilandelayo ukunquma iphimbo. Hlola intambo ngokumelene nokuma ngakunye nge-pitch gauge (eyaziwa nangokuthi ikamu) kuze kutholakale ukufanelana okuphelele. Ezinye izimo zentambo yesiNgisi neye-metric zifana kakhulu, ngakho-ke kungathatha isikhathi.
Misa izinga lephimbo
Isinyathelo sokugcina ukusungula izinga le-pitch. Ngemva kokunqunywa kobulili, uhlobo, ububanzi obuncane kanye nephimbo lentambo, izinga lokuhlonza intambo lingabonakala ngomhlahlandlela wokuhlonza intambo.
