Yintoni i-ISO 12151-2 kwaye yeyiphi inguqulelo yamva nje?
Isihloko se-ISO 12151-2 ludibaniso lwamandla e-hydraulic fluid kunye nokusetyenziswa ngokubanzi - i-hose fittings-part 2: I-Hose fittings kunye ne-ISO 8434-1 kunye ne-ISO 8434-4 24 ° i-cone connector iphela nge-O-rings.
Ushicilelo lokuqala lukhutshwe kwi-2003 kwaye lulungiswe yiKomiti yezoBugcisa ISO/TC 131, iinkqubo zamandla e-Fluid, i-Subcommittee SC 4, izixhumi kunye neemveliso ezifanayo kunye namacandelo.
Inguqulelo esebenzayo yangoku yi-ISO 12151-2:2003, jonga ngezantsi kwephepha leqweqwe lomgangatho we-ISO 12151-2, kunye nekhonkco kwiwebhusayithi ye-ISO.

I-ISO 12151-2 yavela kwi-DIN 20066 (ekhutshwe ngo-1982) i-24 ° i-cone hose fittings, ngoko ke i-24 ° i-cone hose ifakela isetyenziswe ngokubanzi eJamani, eYurophu njl.
Ngowuphi umxholo ocaciswa yi-ISO 12151-2?
I-ISO 12151-2 ichaza iimfuno ngokubanzi kunye nobukhulu boyilo kunye nokusebenza kofakelo lwe-hose ene-24 ° isidibanisi sekhowuni esiphela nge-O-rings, ngokuhambelana ne-ISO 8434-1.Ezi zixhobo ze-hose zenziwe nge-carbon steel kwaye zenzelwe ukusetyenziswa kunye ne-hoses kunye ne-nominal ngaphakathi kwe-diameters ukusuka kwi-5 mm ukuya kwi-38 mm (iquka).
Ukuba ufuna izinto ngaphandle kwe-carbon steel, kulungile kwaye nceda ubuze inkonzo yethu yabathengi.
Ngaba ophumeleleyo unemveliso ehambelanayo ye-ISO 12151-2?
Ophumeleleyo biza olu hlobo lombhobho olufanelekileyo njenge-24 ° i-cone hose ehambelanayo, kunye noluhlu olufanelekileyo oluyindoda inxalenye.yi 104xx (L series) kunye 105xx (S series), kwaye series female yi 204xx (L series) kunye 205xx (S series).Ngezantsi ngumfanekiso oqhelekileyo wolu ngcelele.
104xx kunye 105xx series uhlobo eqhelekileyo
204xx kunye 205xx series uhlobo eqhelekileyo
Ophumeleleyo i-cone 24° ifaka ithumbu le-cone sebenzisa i-cap nut kunye ne-wire nut, ubude obuhlukeneyo bokulahla bokulinganisa ithumbu eligobayo, iinkcukacha jonga iphepha lekhathalogu.[Ikhonkco lokuKhuphela uluhlu]
Ophumeleleyo i-24° ye-cone hose ifaka isahlulo sendibano yethumbu evavanyiweyo ngokuhambelana ne-ISO 19879, kunye nendibano yethumbu epheleleyo evavanyiweyo ngokuhambelana ne-ISO 6605.
Imfuno yokugqiba kwi-ISO 12151-2 yi-72 h engathathi hlangothi yokuvavanya ityuwa-isitshizi ngokuhambelana ne-ISO 9227 kwaye akukho mhlwa obomvu, iindawo eziphumeleleyo zigqithise kakhulu imfuneko ye-ISO 12151-2.
Apha ngezantsi kukho ukucaciswa kwe-ISO kunye nomfanekiso wokuvavanya ityuwa yokutshiza.
