Iyini i-ISO 12151-1 futhi iyiphi inguqulo yakamuva?
I-ISO 12151-1 Isihloko se-ISO 12151-1 siwukuxhunywa kwamandla oketshezi we-hydraulic kanye nokusetshenziswa okujwayelekile - ukufakwa kwepayipi -Ingxenye 1: Ukufakwa kwepayipi elineziphetho ze-ISO 8434-3 O-ring face seal.
Uhlelo lokuqala lwakhululwa ngo-1999 futhi lwalungiselelwa IKomidi Lobuchwepheshe ISO/TC 131, amasistimu kagesi we-Fluid, Ikomidi elincane le-SC 4, izixhumi nemikhiqizo nezingxenye ezifanayo.
Inguqulo yamanje evumelekile yi-ISO 12151-1:2010 kanye ne-AMD 1:2017, bona ngezansi kwekhasi lekhava le-ISO 12151-1 ejwayelekile, kanye nesixhumanisi esivela kuwebhusayithi ye-ISO.
I-ISO 12151-1 yavela ku-SAE J516 (eyakhishwa ngo-1952) ukufakwa kwepayipi le-O-ring face seal, ngakho ukufakwa kwepayipi le-ORFS kusetshenziswa kabanzi eMelika.
Ikuphi okuqukethwe i-ISO 12151-1 ecacisayo?
I-ISO 12151-1 icacisa izidingo ezijwayelekile nezinobukhulu zokuklama nokusebenza kokufakwa kwepayipi elineziphetho ze-O-ring yobuso ngokuhambisana ne-ISO 8434-3, eyenziwe ngensimbi ye-carbon, yamapayipi okuzisholo ngaphakathi kwamadayamitha angu-6,3 kuya ku-38. mm, ngokuhlanganisa, ngokuhambisana ne-ISO 4397.
Uma ufuna izinto zokwakha ngaphandle kwe-carbon steel, kulungile futhi sicela ubuze isevisi yethu yamakhasimende.
Ingabe Owinile unomkhiqizo ohambisanayo we-ISO 12151-1?
Owinile shayela lolu hlobo lokulingana kwepayipi njenge-ORFS (O-Ring Face Seal) ifaka ipayipi, kanye nochungechunge lokulingana kwabesilisa ingxenye engunombolo.ingu-142xx kanti uchungechunge lwabesifazane luyi-242xx.Ngezansi kunesithombe esijwayelekile salolu chungechunge.
142xx uchungechunge uhlobo olujwayelekile
242xx uchungechunge uhlobo olujwayelekile
Ukufakwa kwepayipi le-ORFS eliwinile kunekholiyumu ehlukile, njenge-hex noma ngaphandle kwe-hex yokulinganisa kwabesifazane, isitayela A (indawo evalekayo ayidalulwanga) noma isitayela B (indawo yokuvala isobala), ubude obuhlukile bokudonsa bokufakwa kwepayipi eligobayo, imininingwane bheka ishidi lekhathalogi ukuze uthole ukukhetha kwamakhasimende. .[Isixhumanisi Sokulanda ikhathalogi]
Owinile we-ORFS ingxenye efaka ipayipi lepayipi elihlolwe ngokuvumelana ne-ISO 19879, kanye nokuhlanganiswa kwepayipi eliphelele elihlolwe ngokuvumelana ne-ISO 6605.
Isidingo sokuqeda ku-ISO 12151-1 ukuhlolwa kwesifutho sikasawoti esingama-72 h ngokuhambisana ne-ISO 9227 futhi akukho nokugqwala okubomvu, izingxenye zabawinile zidlula kude imfuneko ye-ISO 12151-1.Ngezansi ukucaciswa kwe-ISO kanye nesithombe sokuhlola isifutho sikasawoti Owinile.
