Ungakwazi ukubala ubude obufanele bokusika be-extrusion yesitoko sentambo yerabha ngesibali esilandelayo.Sicela uqinisekise amanani alungile we-diameter yangaphakathi (ID) kanye ne-cross-section yephrofayela (CS) kuqala bese wenza izibalo ezilula.
Ngokwesibonelo:
Esebenzisa intambo yobubanzi obungu-10mm (CS), umsebenzisi ufuna ukwenza indandatho ye-o evamile enobubanzi obungu-300-mm ngaphakathi.
Isibalo sokusika ubude bentambo ukwenza i-o-ring edingekayo simi kanje:
300 (ID)+10 (CS)= 310
310×3.1415926= 973.89mm
Intambo kufanele isikwe ibe ubude obungu-973.89 mm ukuze kwenziwe i-o-ring edingekayo.
Usayizi wentambo evamile ulinganiswa ngobubanzi bephrofayela.Leli shadi libonisa kokubili osayizi be-imperial kanye ne-metric.Ithebula futhi libonisa ukubekezelelwa kwentambo ye-o-ring, ukuze ukwazi ukubala ngokunembile ukuthi intambo ingalungela uhlelo lwakho olunembile.Phakathi kwalaba sayizi, usayizi wamayintshi uhluke kancane kusayizi we-AS568 o-ring, kuyilapho usayizi wemethrikhi usekelwe kakhulu emakethe yase-china nakwezinye izimakethe zaphesheya.Ngokuyisisekelo, singakwazi ukukhiqiza bonke laba osayizi bezintambo ngekhwalithi ephezulu, intengo encintisana kakhulu, kanye nokulethwa okusheshayo kakhulu.Uma usayizi othile ungekho ohlwini lwetafula, sicela usithinte ukuze uxoxe ngentambo yakho oyifisayo.Ukupakishwa kwentambo yenjoloba kungaba lula kakhulu noma kuboshwe ku-roller.Sicela u-ode ngokwezidingo zakho zangempela.
