Ama-Seal nama-O-rings asetshenziswa kakhulu ezimbonini ezahlukene ukuvimbela ukuvuza nokugcina ubuqotho bezinto ezingaphansi kwezinguquko zengcindezi noma izinga lokushisa.Ukuthuthuka kwakamuva ku-static seal kanye nobuchwepheshe be-o-ring kuthuthukisa ukuthembeka kokusebenza, ukuqina kanye nokusebenza ngempumelelo kwezindleko.
Izigxivizo eziqinile zisetshenziswa ezinhlelweni ezinganyakazi futhi zenzelwe ukugcina uphawu phakathi kwezingxenye ezimbili ezinganyakazi.Zingenziwa ngezinto ezahlukene ezifana nerabha, i-Teflon ne-silicone.Lezi zimpawu zisetshenziswa ezimbonini ezahlukahlukene ezifana nokucubungula amakhemikhali, uwoyela negesi, nokudla nesiphuzo.
Enye yentuthuko yakamuva kubuchwepheshe bokuvalwa kwe-static ukuthuthukiswa kwezigxivizo zokushisa okuphezulu.Lezi zimpawu zingamelana namazinga okushisa adlulele, zizenze zilungele ukusetshenziswa kwezimboni ezifaka ukuchayeka kokushisa okuphezulu.Lezi zimpawu zenziwe ngezinto eziphambili ezimelana nokuwohloka kokushisa, ukuguguleka kanye ne-oxidation.
Ngaphezu kwezimpawu ezimile, izindandatho ze-O ziyizingxenye ezibalulekile ezimbonini eziningi, ezihlanganisa ezezimoto, i-aerospace kanye nokukhiqiza.Lezi zimpawu zisetshenziswa njengendlela ethembekile neyongayo yokuhlinzeka ngokucindezela nokulawula uketshezi.Zingenziwa ngezinto ezihlukahlukene futhi ukusetshenziswa kwazo kuncike ekusetshenzisweni kwazo ezikufunayo.
Enye yentuthuko eminingi kubuchwepheshe be-O-ring kwaba ukwethulwa kwama-O-rings anempilo yeshelufu eyandisiwe.Lezi zimpawu zingagcinwa isikhathi eside ngenkathi zihlala zisesimweni esiphezulu.Le ntuthuko ibalulekile ngoba iqeda isidingo sokushintsha izigxivizo izikhathi eziningi njengoba ziwohloka ngokuhamba kwesikhathi.
Enye intuthuko enkulu kubuchwepheshe be-O-ring ukusetshenziswa kwezinto ezingamelana nezimo ezimbi kakhulu ngenkathi zigcina ubuqotho bazo.Lezi zinhlobo zama-o-rings zenzelwe ukumelana namakhemikhali anonya, izicelo zokucindezela okukhulu kanye namazinga okushisa aphezulu.Ukusetshenziswa kwale O-ring kuthuthukisa ukwethembeka nokuqina ezimbonini ezifana ne-aerospace kanye nowoyela negesi.
Kafushane, ukuthuthuka kwe-static seal kanye nobuchwepheshe be-O-ring kube nomthelela omuhle ekusebenzeni kahle nokuphepha ezimbonini ezahlukahlukene.Ukwethulwa kwezigxivizo eziqinile ezisezingeni eliphezulu nezindandatho ze-O-impilo ende kwandisa imijikelezo yokusebenza futhi kunciphisa izindleko kuyilapho kugcinwa ubuqotho bomkhiqizo.Ukwengeza, ukusetshenziswa kwezinto ezingamelana nezimo ezinzima kukhulisa ukuqina nokuthembeka kukonke, kube lula ukuthuthukiswa kobuchwepheshe bokuvala uphawu.
