Gupakira glande ya PTFE nigisubizo cyiza kandi cyizewe cyo gufunga gikoreshwa mubikorwa bitandukanye byinganda.Itanga uburyo bwiza bwo gufunga no kuramba, bigatuma ihitamo ryambere ryo gufunga ibiti nigiti cya valve.Muri iki kiganiro, tuzareba uburyo gupakira gland ya PTFE ikora nimpamvu ifatwa nkimwe muburyo bwiza bwo gushiraho ikimenyetso kiboneka.
Gupakira gland nibikoresho bifunga kashe kugirango birinde kumeneka pompe, valve nibindi bikoresho bizunguruka.Mubisanzwe bikozwe mubikoresho bikozwe cyangwa bigoramye nka grafite, Teflon, cyangwa aramid fibre.Ibi bikoresho byatoranijwe kubushobozi bwabo bwo guhangana nubushyuhe bwo hejuru, umuvuduko hamwe n’ibidukikije bikabije.
PTFE, cyangwa polytetrafluoroethylene, ni fluoropolymer ya syntetique izwi cyane kubera imiti irwanya imiti kandi ifite ubukana buke.Bizwi cyane nka Teflon kandi ni ikirango cyanditswemo na sosiyete ikora imiti Chemours.PTFE irwanya imiti myinshi, acide na solde, bigatuma biba byiza mugupakira gland aho ibikoresho bifunga bigomba guhangana nibitangazamakuru bikaze.
Ihame ryakazi ryo gupakira gland ya PTFE iroroshye ariko ikora neza.Ibikoresho byo gupakira bishyirwa hafi yumutwe cyangwa uruti hanyuma bigahuzwa na glande.Glande ni kashe ya mashini, iyo ikomejwe, ikora kashe itekanye, idafite amazi.Gucomeka kw'ibikoresho byo gupakira bitera inzitizi hagati y'uruti cyangwa inkoni n'inzu, bikabuza amazi cyangwa gaze guhunga.
Kimwe mu byiza byingenzi byo gupakira gland ya PTFE nubushobozi bwayo bwo guhuza imiterere yikibaho cyangwa igiti cya valve, bigatuma kashe ifatika ndetse no mubikorwa bitandukanye.Ihinduka ryemerera gupakira kugirango yishyure igiti icyo aricyo cyose cyangwa igiti kidahuye cyangwa ingendo, birinda kumeneka no kugabanya ibisabwa byo kubungabunga.
Coefficient nkeya ya PTFE ituma imikorere ikora neza kandi igabanya kwambara kumutwe cyangwa kuruti.Ntabwo ibyo bigabanya gusa amahirwe yo kumeneka, binagura ubuzima bwigice.Byongeye kandi, gupakira gland ya PTFE ifite coefficient nkeya yo kwagura ubushyuhe, bigatuma irwanya ihindagurika ryubushyuhe hamwe nubushyuhe bwumuriro.
Glande ipakira ikozwe muri PTFE nayo izwiho ibyiza byo kwisiga.Igumana firime yoroheje yo gusiga ku giti cyangwa ku giti, bikagabanya ubukana no kwirinda kwambara cyane.Iyi mikorere yo kwisiga ituma gupakira gland ya PTFE ibereye rimwe na rimwe byumye-bikora cyangwa bidahagije byo gusiga amavuta.
Byongeye kandi, gupakira glande ya PTFE irashobora kwihanganira ubushyuhe buva kumiterere ya kirogenike kugeza ubushyuhe bukabije.Igumye itekanye kandi ikomeza ibimenyetso byayo no mubushyuhe bwo hejuru, bigatuma ihitamo kwizerwa kubisabwa.
Muri make, gupakira gland ya PTFE nigisubizo cyiza kandi gihindagurika cyo gufunga uburyo butandukanye bwo gukoresha inganda.Imiti idasanzwe irwanya imiti, imiterere mike yo guterana hamwe nibikorwa byiza byo gufunga bituma iba ihitamo ryambere ryo gufunga ibiti nigiti cya valve.Haba ahantu h'ubushyuhe bwo hejuru, inganda zitunganya imiti, cyangwa izindi porogaramu zisaba, gupakira gland ya PTFE itanga kashe itekanye, idasohoka ituma ibikoresho bikora neza mugihe bigabanya ibisabwa byo kubungabunga.
