Uyini usayizi wokubhoboza wempompi ye-1/8 NPT?
Okuqukethwe
Kulesi sihloko, ngizokusiza ukuthi unqume uhlobo lokubhola olulungile nosayizi wokuthepha kwakho okungu-1/8" we-NPT.
Ompompi be-NPT banezintambo ezicijile futhi batholakala ngosayizi abahlukahlukene. Njengengcweti enolwazi, ngiyazi ukuthi kubaluleke kangakanani ukukhetha usayizi olungile wokubhoboza ukwenza imbobo efanelekile yompompi abangu-1/8 NPT. Uma kungenjalo, ukujula nobubanzi bembobo kuzovimbela umpompi we-NPT ukuthi ungahlali kahle.
Hlola ishadi lemethrikhi elilungile ukuze uthole usayizi olungile wokubhoboza we-1/8 NPT kampompi. I-11/32″ “R” drill ilungele ukufaka ompompi be-NPT abangu-1/8″.
Ngizokutshela okwengeziwe ngezansi. Ake sijule.
Ibhithi yokubhoboza usayizi olungile wompompi be-NPT
Kubaluleke kakhulu ukusebenzisa usayizi olungile wokubhola ukufaka impompi ye-NPT engu-1/8. Uma kungenjalo, umpompi we-1/8 NPT ngeke ubambe. Ingagqashula nakuleyo nto bese idala umonakalo.
Ngakho yimuphi usayizi wokubhoboza okufanele ukhethe?
Kufanele ukhethe u-11/32, "R" wokubhoboza uma usebenzisa impompi ye-NPT engu-1/8.
Thepha 1/8 NPT
Ukuthepha kwe-NPT (National Pipe Thread) kuvame ukudala kabusha imicu eyonakele noma ukwenza imicu emisha kumapayipi.
Ku-NPT, isigaba sochungechunge sangempela sicishiwe. Izinombolo azihambisani nosayizi oyintshi ngenxa yokuthi (ama-NPT taps) asuselwa kumkhakha namasayizi wamapayipi. (1)
Ngalo mqondo, ububanzi bompompi ongu-1/8" we-NPT akuwona u-0.125". Isekelwe emicu ekupheleni kwepayipi elingu-1/8". Ngakho-ke, cishe i-0.405" ku-diameter "enkulu".
Imicu, iziphetho zamapayipi, nezimbobo zokuthi 1/8 NPT zicishiwe. Ukuncipha kwenza zingavuzi kakhulu uma zihlanganiswa.
Ngakho-ke uma ubeka itheyiphu noma igrisi yepayipi ezingxenyeni zikampompi ze-1/8 NPT futhi uziqinise ngokuqinile, ngeke ubone noma yikuphi ukuvuza. (2)
Amanothi abalulekile: Ungasiki i-1/8 in. Thepha nge-NPT njengompompi ovamile. Akufanele iphahlazeke endabeni. Vele uyithephe ngokwanele ukuze uthole i-taper enhle yokufaka.
Ngincoma ukuthi uyithephe phansi ibe yiyintshi engu-3/4. Ukucindezela yonke indlela phansi kuzokhulisa ikhoni, kuyenze ibe nkulu kakhulu.
Uyibhola Kanjani I-1/8 NPT Tap
Ukubhoboza impompi ye-1/8 NPT kulula:
Isinyathelo 1: Maka indawo ofuna ukuyibhola
Ungasebenzisa noma yiliphi ithuluzi elifanelekile, elifana nomaka, ukumaka indawo.
Isinyathelo sesi-2: Thola i-drill yosayizi olungile
Njengoba sekushiwo, thatha i-drill "R", okungukuthi, i-drill enobubanzi obuyi-11/32 amayintshi.
Isinyathelo 3: Geza Imbobo
Gcoba ngokucophelela endaweni oyimake esinyathelweni sokuqala. Njengoba usebenzisa i-11/32 drill, ukujula nobubanzi bembobo kuzoba kuhle empompini ye-NPT engu-1/8, ezongena kahle emgodini.
Isinyathelo sesi-4: Faka i-1/8 NPT Tap
Ekugcineni, faka umpompi we-NPT ku-drill bese uyibeka phezu kwezinto. Phakathi nokufaka, yithephe ku-3/4 wengxenye efakwe imiluko njengenhla.
Ukufingqa
Ukuba ne-drill bit elungile kubalulekile uma usebenzisa i-1/8 NPT noma omunye umpompi wosayizi we-NPT. Lokhu kuqinisekisa ukuvuleka okuphelele nokufakwa kwe-faucet. Ungahlala ubhekisela kushadi lemethrikhi uma ukhohlwa usayizi wokubhoboza ongawusebenzisela usayizi onikeziwe wokuthepha we-NPT.
