Umbhobho yeyona nxalenye ibalulekileyo yenkqubo yolwelo egqibeleleyo. Ngaphambi kokukhetha umbhobho, kubalulekile ukuqonda isixhumi sepayipi, iimpawu zolwelo kunye nendawo yokufakela, ukuze kuqinisekiswe iimeko ekufuneka zihlangatyezwe ngumbhobho ofunekayo yinkqubo, ezifana nemeko yomphezulu, iimfuno zezinto, umgangatho wobunzima, ubukhulu bodonga, ububanzi kunye nobude. Emva kokuqokelela ulwazi olungentla, ukhetho oluchanekileyo lombhobho lunokuhlangabezana nofakelo lwenkqubo kwaye luqinisekise ukusebenza okuthembekileyo kwenkqubo ngaphandle kokuvuza.
Hikelok'siimveliso zemibhobhobandakanyaityhubhukunye nombhobho. Ungakhetha njani xa uqhagamshela inkqubo? Singayiqonda ngokweenkcukacha umahluko wabo kwiinkalo ezine ezilandelayo, size emva koko senze isigqibo kunye neemeko zokusebenza.
1. Iinkcukacha ezahlukeneyo kunye nokuchonga.Ityhubhu imelwe bububanzi bangaphandle kunye nobukhulu bodonga, kubandakanya iityhubhu eziqhekeziweyo kunye neetyhubhu ze-metric. Ityhubhu imelwe yi-NPS (ubungakanani bepayipi eqhelekileyo) + ishedyuli Hayi. Apha i-NPS ayisiyo ububanzi bangaphandle bombhobho, kodwa bubungakanani obuqhelekileyo.
2. Imigangatho eyahlukeneyo yemveliso. Ityhubhu isebenzisa umgangatho we-ASTM A269 A213 SA213, kwaye umphezulu ngokubanzi kufuneka ufakwe i-anneal, ubunzima bungadluli kwi-90hrb. Ityhubhu isebenzisa umgangatho we-ASTM A312 SA312, kwaye akukho mfuneko yemeko yomphezulu. Ngenxa yokuba imigangatho yahlukile, ukunyamezelana kunye neemeko zezinto zetyhubhu kunye nombhobho nazo zahlukile.
3. Ukuchonga uxinzelelo okwahlukileyo.Kuba ukunyamezelana kufanele kuqwalaselwe kuyilo, kwaye ukunyamezelana kwemigangatho efanelekileyo yetyhubhu kungqongqo kuneyombhobho, ngoko ke i-pressure bearing ebaliweyo nayo yahlukile. Ityhubhu ingamela ngokuchanekileyo i-pressure psi, ngelixa umbhobho uhlala usebenzisa i-PN ukumela uxinzelelo.
4. Usetyenziso olwahlukeneyo. Ngenxa yeenkcukacha zayo ezininzi, kulula ukuzigoba, ukuziqhelanisa noqhagamshelwano lweepayipi ezahlukeneyo, ulwakhiwo oluncinci, ukufakelwa nokugcinwa okulula, umjelo wokuhamba kakuhle kunye nokwehla koxinzelelo oluncinci, iityhubhu zihlala zisetyenziswa kwinkqubo yoqhagamshelo lwezixhobo. Ipayipi ayinazo iinkcukacha ezininzi kwaye inobunzima obuphezulu, ngoko ke ayinakudityaniswa ngokulula, ngoko ke isetyenziswa kakhulu kwinkqubo yepayipi yamandla kunye nenkqubo yepayipi.
In Iimveliso zikaHikelok, xa uodolaityhubhu, ingasetyenziswa kunyeizixhobo zetyhubhu ezimbini ze-ferrule, iivalvu zenaliti, iivalvu zebhola, iivalvu zokhuseleko, iivalvu zokujongakunye nezinye iivalvu.i-siphonyenziwe ngetyhubhu ngenkqubo ethile.iinkqubo zokuthatha iisampulu, ityhubhu nayo iyinxalenye ebalulekileyo yokudibanisa.
Ukuze ufumane iinkcukacha ezithe vetshe malunga noku-odola, nceda ujonge ukhethoiikhathalogukuvuliweIwebhusayithi esemthethweni kaHikelokUkuba unemibuzo yokukhetha, nceda unxibelelane nabasebenzi abangochwephesha bokuthengisa kwi-intanethi baseHikelok abasebenza iiyure ezingama-24.
