Ukwakhiwa kohlelo lwamanzi ezimboni akuhlukaniseki ku-ukufakwa kwamapayipi ezinsimbinjengokuxhumeka. Ezinhlelweni ezahlukahlukene ezifana nendawo enomfutho ophezulu, izimo zokusebenza ezimbi kakhulu noma ukuthuthwa okuyingozi kwegesi noketshezi, inani elincane lezinto ezifakwe ngentambo lingabonakala yonke indawo. Ukusebenza kwazo okuhle kakhulu ekumelaneni nomfutho, ukumelana nokudlidliza kanye nokuvala kusiza uhlelo loketshezi ukuthi lusebenze ngokuphepha nangokuzinzile, okwenza luthembeke futhi lusetshenziswe abantu abaningi.
Ukuze wakhe uhlelo oluphephile loketshezi, isisekelo ukukhetha intambo efanele. Uma ufuna ukukhetha intambo efanele, udinga ukuyikhomba kuqala.
Izinhlobo zezintambo ezivamile ze-Hikelok
Kunezinhlobo ezimbili zezintambo ezivame ukusetshenziswa yiHikelok, enye intambo yokuxhuma, ehlukaniswe ngentambo ye-M kanye nentambo ye-UN, kanti enye intambo yepayipi, ehlukaniswe ngentambo ye-NPT, intambo ye-BSPP kanye nentambo ye-BSPT. Leli phepha lithatha kakhuluintambo yepayipinjengesibonelo.
Izinhlobo zezintambo zamapayipi
(1) Intambo ye-NPT(Intambo Yepayipi Ejwayelekile YaseMelika), kusetshenziswa i-ASME B1 20.1 ejwayelekile, i-engeli yephrofayili yamazinyo ingu-60 °, ingxenye ephezulu kanye nephansi lamazinyo kusesimweni esiphansi, kanti i-taper yentambo eyindilinga ingu-1 ∶ 16, ngokuvamile ebizwa ngokuthi intambo ye-taper.
(2) Intambo ye-BSPP, ehambisana nentambo ye-G (iBritish Standard Parallel Pipe), isebenzisa indinganiso ye-ISO 228-1, i-engeli yephrofayili yamazinyo ingu-55 °, ingxenye ephezulu yamazinyo kanye nephansi kumise okwe-arc, kanti intambo yangaphakathi neyangaphandle iyintambo yepayipi eliyindilinga, ngokuvamile ebizwa ngokuthi intambo ehambisanayo.
(3) Intambo ye-BSPT, ehambisana nentambo ye-R (intambo yepayipi yokuvala ejwayelekile yaseBrithani), isebenzisa indinganiso ye-ISO 7-1, i-engeli yephrofayili yamazinyo ingu-55 °, ingxenye ephezulu yamazinyo kanye nephansi kuyindilinga, kanti i-taper yentambo eyindilinga ingu-1∶16. Ngokuvamile eyaziwa ngokuthi intambo ye-taper.
Indlela yokuqinisekisa imininingwane yezintambo ezintathu zamapayipi
Kusukela kolwazi olungenhla, singazi ukuthi imicu yepayipi ingahlukaniswa ngezigaba ezimbili: intambo ye-taper kanye nentambo ehambisanayo. Ngakho-ke, lapho sihlukanisa intambo, kumele siqale sihlukanise ukuthi ngabe iyintambo ye-taper noma intambo ehambisanayo.
Ukuhlonza kwangaphambili
Ukwahlulela kokuqala kungenziwa ngokuya ngokuthi intambo ine-taper yini. Sebenzisa i-vernier caliper ukukala ububanzi phakathi kweziqongo zezinyo entanjeni yokuqala, yesine neyokugcina egcwele ngokuya ngesimo esiboniswe esithombeni esingezansi. Uma ububanzi bukhula noma buncipha kancane kancane, kubonisa ukuthi intambo ine-taper, okuyintambo ye-BSPT noma intambo ye-NPT entanjeni ye-taper. Uma wonke ububanzi bufana, kubonisa ukuthi intambo ayina-taper futhi iyintambo ye-BSPP efanayo.
Ukuqinisekiswa okwengeziwe
Kukhona intambo eyodwa kuphela ye-BSPP yentambo ehambisanayo, ngakho-ke kuyadingeka ukuhlukanisa kabanzi ukuthi ngabe intambo ye-BSPT noma intambo ye-NPT entanjeni ekhonjisiwe.
Ukulinganiswa kwe-engeli yephrofayili yezinyo: yahlulelwe ngokwe-engeli yephrofayili yamazinyo, intambo ye-BSPT ene-engeli yephrofayili yamazinyo engu-55 ° kanye nentambo ye-NPT ene-engeli yephrofayili yamazinyo engu-60 °.
Intambo ye-BSPT Intambo ye-NPT
Bheka ukuma kwezinyo: hlulela ngokuma kwengxenye ephezulu yezinyo kanye nengxenye engezansi yezinyo. Intambo ye-BSPT ingaphezulu eliyindilinga kanye nengxenye engezansi eyindilinga, kanti intambo ye-NPT ingaphezulu eliyisicaba kanye nengxenye engezansi eyindilinga.

Isahlulelo sokugcina
Amathuluzi amabili alandelayo ayadingeka ukuqinisekisa ngokunembile uhlobo lwentambo.
Indlela 1: sebenzisa igeyiji yentambo bese ukhetha igeyiji yentambo ehambisanayo ukuze uqinisekise okokugcina. Intambo elinganisiwe iboshwe kahle ngegeyiji yentambo. Uma imithetho yokuhlola igeyiji yentambo ehambisanayo idluliswa, incazelo yentambo iyincazelo yangempela yentambo elinganisiwe.
Indlela yesi-2: sebenzisa i-tooth gauge bese ukhetha i-tooth gauge ehambisanayo ukuze uqhathanise kuze kube yilapho i-tooth gauge ifanelana kahle ne-thread elinganisiwe, khona-ke i-thread specification iyi-specification yangempela ye-thread elinganisiwe.
Ngaphezu kwezindlela ezingenhla, singahlola nezindinganiso zentambo ezihambisanayo zezintambo ezintathu ngemva kokulinganisa ububanzi bomqhele wentambo nge-vernier caliper nokwahlulela intambo ye-taper kanye nentambo ehambisanayo, bese sithola incazelo yentambo enobubanzi bomqhele wentambo obufanayo nentambo elinganisiwe ku-thread standard ukuze kuqinisekiswe okwengeziwe, kodwa isahlulelo sokugcina sisadinga usizo lwe-thread gauge kanye ne-tooth gauge.
Uma uthenga izinto zokufaka amapayipi eHikelok, kunconywa ukuthi uzifake futhi uzisebenzise kanye nama-valve okulawula eHikelok. Ungakhethaivalvu yenaliti, ivalvu yebhola, ivalvu yokusiza elinganayo, ivalvu yokulinganisa, ivalvu yokuhlola, ama-valve manifold, uhlelo lokuhlola amasampula, njll., ukuze kwenziwe ukuxhumana kohlelo loketshezi kuphephe futhi kusebenze kahle kakhudlwana.
Ukuze uthole imininingwane eyengeziwe yoku-oda, sicela ubheke okukhethiweamakhathalogikuvuliweIwebhusayithi esemthethweni kaHikelokUma unemibuzo yokukhetha, sicela uxhumane nabasebenzi bezokuthengisa abangochwepheshe be-Hikelok abasebenza amahora angama-24 online.
