Ukwakhiwa kwesistimu yoketshezi lwezimboni ayinakuhlukaniswa neizinsimbi zamapayipi okufakwayonjengokuxhumana. Kuzinhlelo zokusebenza ezihlukahlukene ezifana nemvelo enengcindezi ephezulu, izimo zokusebenza eziyingozi kakhulu noma ezokuthutha eziyingozi zegesi-uketshezi, isibalo esincane sokufakwa kwentambo singabonakala yonke indawo. Ukusebenza kwabo okuhle kakhulu ekumelaneni nokucindezela, ukumelana nokudlidliza kanye nokuvala kusiza isistimu yoketshezi ukuthi isebenze ngokuphepha nangokuzinza, okubenza bathenjwa futhi basetshenziswe abantu abaningi.
Ukwakha isistimu yoketshezi ephephile, isisekelo siwukukhetha intambo efanele. Uma ufuna ukukhetha umucu olungile, udinga ukuwukhomba kuqala.
Izinhlobo zezintambo ezijwayelekile ze-Hikelok
Kunezinhlobo ezimbili zezintambo ezivame ukusetshenziswa yi-Hikelok, enye intambo yokuxhuma, ehlukaniswe ngentambo ye-M ne-UN, kanti enye intambo yepayipi, ehlukaniswe ngentambo ye-NPT, intambo ye-BSPP kanye nentambo ye-BSPT. Leli phepha ngokuyinhloko lithathaintambo yepayipinjengesibonelo.
Izinhlobo zezintambo zamapayipi
(1) Uchungechunge lwe-NPT(I-American National Standard Pipe Thread), kusetshenziswa indinganiso ye-ASME B1 20.1, i-engeli yephrofayili yezinyo ingu-60 °, phezulu nezinyosi kusesimweni sendiza, kanti i-taper yentambo eyi-conical ingu-1 ∶ 16, ngokuvamile ebizwa ngokuthi i-taper thread. .
(2) Intambo ye-BSPP, ehambisana nentambo ye-G (i-British Standard Parallel Pipe), isebenzisa indinganiso ye-ISO 228-1, i-engeli yephrofayili yezinyo ingu-55 °, phezulu nezinyosi zimise okwe-arc, kanti intambo yangaphakathi nengaphandle iyintambo yepayipi eyicylindrical, ngokuvamile ebizwa ngokuthi intambo ehambisanayo.
(3) Intambo ye-BSPT, ehambisana nentambo engu-R (umcu wepayipi elivalekayo elivamile laseBrithani), isebenzisa indinganiso ye-ISO 7-1, i-engeli yephrofayela yezinyo ingu-55 °, phezulu nezinyosi kuyi-arc eyindilinga, futhi i-taper yentambo eyikhonikhi ngu-1∶16. Ngokuvamile eyaziwa ngokuthi i-taper thread.
Ukuqinisekisa kanjani ukucaciswa kwemicu yepayipi emithathu
Kusukela olwazini olungenhla, singakwazi ukwazi ukuthi izintambo zamapayipi nazo zingahlukaniswa zibe izigaba ezimbili: intambo ye-taper kanye nentambo ehambisanayo. Ngakho-ke, lapho sihlukanisa intambo, kufanele siqale sihlukanise ukuthi intambo ye-taper noma intambo ehambisanayo.
Umazisi wokuqala
Isahlulelo sokuqala singenziwa ngokuya ngokuthi intambo ine-taper. Sebenzisa i-vernier caliper ukuze ulinganise ububanzi phakathi kwamathiphu ezinyo kuntambo yokuqala, yesine neyokugcina egcwele ngokuhambisana nendawo eboniswe emfanekisweni ongezansi. Uma ububanzi bukhula kancane kancane noma buncipha, kubonisa ukuthi intambo ine-taper, okuyintambo ye-BSPT noma intambo ye-NPT kuntambo ye-taper. Uma wonke ama-diameter afana, kubonisa ukuthi intambo ayinayo i-taper futhi iyintambo ehambisanayo ye-BSPP.
Ukuqinisekisa okwengeziwe
Kunentambo eyodwa kuphela ye-BSPP yochungechunge olufanayo, ngakho-ke kuyadingeka ukuhlukanisa ukuthi intambo ye-BSPT noma intambo ye-NPT kuntambo eyikhonikhi.
Isilinganiso se-engeli yephrofayela yezinyo: yahlulelwa ngokwe-engeli yephrofayili yezinyo, intambo ye-BSPT ene-engeli yephrofayili yezinyo engu-55 ° kanye nentambo ye-NPT ene-engeli yephrofayili yezinyo engu-60 °.
Intambo ye-BSPT ye-NPT
Bheka isimo sezinyo: ijaji ngokuma kwezinyo elingaphezulu nangaphansi kwezinyo. Intambo ye-BSPT ingaphezulu okuyindilinga nangaphansi eyindilinga, futhi umucu we-NPT ungaphezulu nesicaba.
Intambo ye-BSPT ye-NPT
Isahlulelo sokugcina
Amathuluzi amabili alandelayo ayadingeka ukuze kuqinisekiswe ngokunembile uhlobo lochungechunge.
Indlela yoku-1: sebenzisa igeji yentambo bese ukhetha igeji yentambo ehambisanayo ukuze uqinisekise okokugcina. Intambo elinganisiwe igoqwe kahle ngegeji yentambo. Uma imithetho yokuhlola intambo yokulinganisa idluliswa, ukucaciswa kwentambo kuwukucaciswa kwangempela kwentambo elinganisiwe.
Indlela yesi-2: sebenzisa igeji yezinyo bese ukhetha igeji yezinyo elihambisanayo ukuze uqhathanise kuze kube yilapho igeji yezinyo ilingana kahle nentambo elinganisiwe, khona-ke ukucaciswa kwentambo kuwukucaciswa kwangempela kwentambo elinganisiwe.
Ngaphezu kwalezi zindlela ezingenhla, singaphinde sihlole izindinganiso zentambo ezihambisanayo zezintambo ezintathu emva kokulinganisa ububanzi bomqhele wentambo nge-caliper ye-vernier nokwahlulela intambo ye-taper nentambo ehambisanayo, futhi sithole ukucaciswa kwentambo enobubanzi obufanayo bomqhele. njengentambo elinganisiwe esilinganisweni sentambo ukuze kuqinisekiswe okwengeziwe, kodwa isahlulelo sokugcina sisadinga usizo lwegeji yentambo kanye negeji yezinyo.
Lapho uthenga okokufakwa kwepayipi le-Hikelok, kutuswa ukuthi ulifake futhi ulisebenzise kanye nama-valve okulawula e-Hikelok. Ungakhethai-valve yenaliti, i-valve yebhola, i-valve yokusiza ngokulinganayo, i-valve yokulinganisa, hlola i-valve, ama-valve amaningi, uhlelo lwamasampula, njll., ukuze kwenziwe uxhumano lwesistimu yoketshezi luphephe futhi lusebenze kahle.
Ukuze uthole imininingwane eyengeziwe yoku-oda, sicela ubheke okukhethiweamakhathalogikuIwebhusayithi esemthethweni ye-Hikelok. Uma unanoma yimiphi imibuzo yokukhetha, sicela uxhumane nabasebenzi abathengisa ku-inthanethi be-Hikelok bamahora angu-24.
