Iyini i-ISO 12151-2 futhi iyiphi inguqulo yakamuva?
Isihloko se-ISO 12151-2 siwukuxhunywa kwamandla oketshezi olunamanzi kanye nokusetshenziswa okuvamile - ukufakwa kwamapayipi - ingxenye 2: Ukufakwa kwepayipi nge-ISO 8434-1 kanye ne-ISO 8434-4 24° isixhumi sekhoni esigcina ngezindandatho ze-O.
Uhlelo lokuqala lwakhululwa ngo-2003 futhi lwalungiselelwa Ikomiti Lobuchwepheshe ISO/TC 131, amasistimu kagesi we-Fluid, Ikomidi elincane le-SC 4, izixhumi nemikhiqizo nezingxenye ezifanayo.
Inguqulo yamanje evumelekile yi-ISO 12151-2:2003, bona ngezansi kwekhasi lekhava le-ISO 12151-2 ejwayelekile, kanye nesixhumanisi esivela kuwebhusayithi ye-ISO.

I-ISO 12151-2 yavela ku-DIN 20066 (ikhishwe ngo-1982) ukufakwa kwepayipi le-cone engu-24°, ngakho ukufakwa kwepayipi le-cone okungu-24° kusetshenziswa kabanzi eJalimane, eYurophu njll..
Ikuphi okuqukethwe i-ISO 12151-2 ecacisayo?
I-ISO 12151-2 icacisa izidingo ezijwayelekile nezinobukhulu zokuklama nokusebenza kokufakwa kwepayipi elinesixhumi sekhoni engu-24° esiphetha ngo-O-rings, ngokuvumelana ne-ISO 8434-1.Lokhu kufakwa kwe-hose kwenziwa nge-carbon steel futhi kuhloswe ukuthi kusetshenziswe ngamapayipi anama-diameter angaphakathi ngaphakathi kusuka ku-5 mm kuya ku-38 mm (okuhlanganisiwe).
Uma ufuna izinto zokwakha ngaphandle kwe-carbon steel, kulungile futhi sicela ubuze isevisi yethu yamakhasimende.
Ingabe Owinile unomkhiqizo ohambisanayo we-ISO 12151-2?
Owinile shayela lolu hlobo lokulingana kwepayipi njengokulingana kwepayipi lekhoni elingu-24°, kanye nochungechunge lokulingana kwabesilisa ingxenye engunombolo.iyi-104xx (L series) kanye ne-105xx(S series), futhi uchungechunge lwabesifazane luyi-204xx(L series) kanye no-205xx(S series).Ngezansi kunesithombe esijwayelekile salolu chungechunge.
104xx kanye ne-105xx yochungechunge uhlobo olujwayelekile
204xx kanye no-205xx uhlobo olujwayelekile lochungechunge
Owinile 24° ithumbu lekhoni elilingana sebenzisa icap nut nentambo yocingo, ubude obuhlukile bokwehla bokulinganisa ipayipi eligobayo, imininingwane bheka ishidi lekhathalogi.[Isixhumanisi Sokulanda ikhathalogi]
Owinile 24° ingxenye yepayipi lekhoni elilingana lokuhlanganiswa kwepayipi elihlolwe ngokuhambisana ne-ISO 19879, kanye nokuhlanganiswa kwepayipi eliphelele elihlolwe ngokuhambisana ne-ISO 6605.
Isidingo sokuqeda ku-ISO 12151-2 ukuhlolwa kwesifutho sikasawoti esingathathi hlangothi esingama-72 ngokuhambisana ne-ISO 9227 futhi akukho nokugqwala okubomvu, izingxenye eziwinile zedlula kude imfuneko ye-ISO 12151-2.
Ngezansi ukucaciswa kwe-ISO kanye nesithombe sokuhlola isifutho sikasawoti Owinile.
