Yintoni i-ISO 12151-1 kwaye yeyiphi inguqulelo yamva nje?
Isihloko se-ISO 12151-1 ludibaniso lwamandla e-hydraulic fluid kunye nokusetyenziswa ngokubanzi - ukufakwa kwe-hose fittings-part 1: Ukufakwa kwe-Hose fittings kunye ne-ISO 8434-3 O-ring face seal ends.
Ushicilelo lokuqala lukhutshwe kwi-1999 kwaye lulungiswe yiKomiti yezoBugcisa ISO/TC 131, iinkqubo zamandla e-Fluid, i-Subcommittee SC 4, izixhumi kunye neemveliso ezifanayo kunye namacandelo.
Inguqulo esebenzayo yangoku yi-ISO 12151-1: 2010 kunye ne-AMD 1: 2017, jonga ngezantsi kwephepha le-cover ye-ISO 12151-1 esemgangathweni, kunye nekhonkco kwiwebhusayithi ye-ISO.
I-ISO 12151-1 yavela kwi-SAE J516 (eyakhutshwa ngo-1952) i-O-ring face seal fittings, ngoko ke i-ORFS ifaka i-hose esetyenziswa ngokubanzi eMelika.
Ngowuphi umxholo ocaciswa yi-ISO 12151-1?
I-ISO 12151-1 ichaza iimfuno ngokubanzi kunye nobukhulu boyilo kunye nokusebenza kofakelo lwe-hose kunye ne-O-ring face seal ekupheleni ngokuhambelana ne-ISO 8434-3, eyenziwe ngentsimbi ye-carbon, ye-hose ye-hose ngaphakathi kwe-6,3 mm ukuya kwi-38. mm, equkayo, ngokuhambelana ne-ISO 4397.
Ukuba ufuna izinto ngaphandle kwe-carbon steel, kulungile kwaye nceda ubuze inkonzo yethu yabathengi.
Ngaba ophumeleleyo unemveliso ehambelanayo ye-ISO 12151-1?
Ophumeleleyo ubize olu hlobo lokulinganisa i-hose njenge-ORFS (i-O-Ring Face Seal) ifakela umbhobho, kunye nochungechunge lokulinganisa oyindoda inxalenye no.yi 142xx kwaye uthotho lobufazi yi 242xx.Ngezantsi ngumfanekiso oqhelekileyo wolu ngcelele.
142xx series uhlobo eqhelekileyo
242xx uthotho uhlobo eqhelekileyo
Ophumeleleyo umbhobho we-ORFS ufaka i-contour eyahlukileyo, efana ne-hex okanye ngaphandle kwe-hex yokufaneleka kwabasetyhini, isimbo A (umphezulu wokutywina awuvezwanga) okanye isimbo B (umphezulu wokutywina ubhengeziwe), ubude obahlukeneyo bokufakela ithumbu lokugoba, iinkcukacha jonga iphepha lekhathalogu kukhetho lwabathengi. .[Ikhonkco lokuKhuphela uluhlu]
Ophumeleleyo ithumbu le-ORFS lilinganisa inxalenye yendibano yombhobho evavanywa ngokuhambelana ne-ISO 19879, kunye nendibano yethumbu epheleleyo evavanyiweyo ngokuhambelana ne-ISO 6605.
Imfuno yokugqiba kwi-ISO 12151-1 yi-72 h engathathi hlangothi yovavanyo lwesitshizi setyuwa ngokuhambelana ne-ISO 9227 kwaye akukho rusa ebomvu, iindawo eziphumeleleyo zigqithise kakhulu imfuneko ye-ISO 12151-1.Apha ngezantsi kukho ukucaciswa kwe-ISO kunye nomfanekiso wokuvavanya ityuwa yokutshiza.
