Izindandatho Zokusekela ze-PTFE

Incazelo emfushane:

Ama-PTFE Backup-up Rings ayizingxenye ezibalulekile ezinhlelweni zokuvala ezicindezela kakhulu, ezenzelwe ukuqinisa ama-primary seal njenge-O-rings nokuvimbela ukuphuma ngaphansi kokucindezeleka okukhulu kwemishini. Akhiwe nge-polytetrafluoroethylene (PTFE), lawa ma-ring abonisa ukungangeni kahle kwamakhemikhali, amelana cishe nazo zonke izinto ezinamandla okuhlanganisa ama-acid aqinile, ama-alkali aqinile, izinyibilikisi eziphilayo, kanye namagesi aqothulayo. I-coefficient yawo yokungqubuzana ephansi kakhulu kanye nokuqina okuvelele kobukhulu kwenza kube lula ukusebenza okuthembekile ekusetshenzisweni okuguquguqukayo ngamazinga okushisa asukela ku-200°C kuya ku-+260°C. Amandla aphezulu okucindezela kanye nezici ezingaguquki ziqinisekisa ukusatshalaliswa komthwalo ofanele, zivikela ngempumelelo ama-elastomeric seal ekushayweni noma ekulimaleni ngesikhathi sokushintshashintsha kwengcindezi. Ngezakhiwo ezingezona ezinamathelayo kanye nokuhambisana ne-FDA/USP Class VI lapho kudingeka khona, ama-PTFE Backup Rings asetshenziswa kabanzi ezimbonini ezibalulekile njengemishini ye-oyili negesi, ama-reactor okucubungula amakhemikhali, izinhlelo ze-hydraulic, kanye nemishini yezokwelapha efuna ukusebenza ngaphandle kokungcola. Inhlanganisela yazo yokungangeni kwamakhemikhali kanye nokuqina kwemishini kuzenza zibe yinto ebalulekile ekugcineni ubuqotho be-seal ezindaweni zokusebenza ezinzima.

Kuyini Ama-PTFE Backup-up Rings

Ama-Backup Rings e-PTFE (Polytetrafluoroethylene) ayizingxenye ezibalulekile ezinhlelweni zokuvala, eziklanyelwe ngqo ukuvimbela ukuphuma nokuguqulwa kwezimpawu zokuqala ngaphansi kokucindezeleka okuphezulu nezimo ezimbi kakhulu. Lezi zindandatho zinikeza ukwesekwa okubalulekile kuma-O-rings kanye nezinye izimpawu ze-elastomeric, okuqinisekisa ukuthembeka kwesikhathi eside kanye nobuqotho ekusetshenzisweni kwezimboni okudingakalayo.

Izici Eziyinhloko Zezindandatho Zokusekela ze-PTFE

Ukumelana Okumangalisayo Kwamakhemikhali

Ama-PTFE Backup Rings aziwa ngokungangeni kwawo kwamakhemikhali, anikeza ukumelana okungenakuqhathaniswa namakhemikhali ahlukahlukene, okuhlanganisa ama-asidi, izisekelo, izinyibilikisi, kanye namafutha. Lokhu kuwenza abe ngcono ukusetshenziswa ezindaweni ezingcolisa kakhulu lapho ezinye izinto zingawohloka khona.

Ibanga Lokushisa Elibanzi

I-PTFE ingasebenza ngempumelelo kuzo zonke izinhlobo zokushisa ezibanzi, kusukela emazingeni okushisa acwebezelayo kuya ngaphezu kuka-500°F (260°C). Lokhu kuguquguquka kuqinisekisa ukuthi ama-PTFE Backup Rings ahlala esebenza kahle futhi ethembekile kokubili ekushiseni okukhulu kanye nokubanda.

I-Coefficient Ephansi Yokungqubuzana

I-PTFE ine-coefficient ephansi ngokwemvelo yokungqubuzana, okunciphisa ukuguguleka kwezingxenye zokuhlangana futhi kunciphisa ukulahleka kwamandla. Lesi sici sisiza futhi ekunciphiseni ingozi yokugabha nokubanjwa, okuqinisekisa ukusebenza kahle ngisho nangaphansi kwemithwalo ephezulu.

Amandla Aphezulu Okusebenza Kwemishini

Ama-PTFE Backup Rings aklanywe ukuze amelane nokucindezeleka okukhulu kwemishini kanye nokucindezela okuphezulu. Ukwakhiwa kwawo okuqinile kuvimbela ukuphuma kanye nokuguquguquka, ngaleyo ndlela kuthuthukisa ukusebenza okuphelele kanye nobude besikhathi besistimu yokuvala.

Ayingcolisi futhi ayihambisani ne-FDA

I-PTFE iyinto engangcolisi, okwenza ifanelekele ukusetshenziswa lapho ukuhlanzeka nobumsulwa kubalulekile khona, njengasezimbonini zokucubungula ukudla, zemithi, kanye neze-semiconductor. Ama-PTFE Backup Rings amaningi ayatholakala futhi ngamamaki ahambisana ne-FDA, okuqinisekisa ukuthi ahlangabezana nezindinganiso eziqinile zomthetho.

Izicelo ze-PTFE Backup Rings

Izinhlelo ze-Hydraulic kanye ne-Pneumatic

Ama-PTFE Backup Rings asetshenziswa kabanzi kuma-hydraulic cylinders, ama-actuator, kanye nezinhlelo zomoya ukuvimbela ukuphuma kwe-seal nokugcina ubuqotho bokuvala ngaphansi kwengcindezi ephezulu. Ukungqubuzana kwawo okuphansi kanye nokumelana nokuguguleka nakho kunegalelo ekunciphiseni ukulungiswa kanye nokuphila isikhathi eside kwenkonzo.

Ukucubungula Amakhemikhali

Ezitshalweni zamakhemikhali, ama-PTFE Backup Rings anikeza ukwesekwa okuthembekile kwezivalo ezivezwe kumakhemikhali anolaka, ama-asidi, kanye nezinyibilikisi. Ukungangeni kwazo kwamakhemikhali kuqinisekisa ukusebenza kwesikhathi eside ngaphandle kokuwohloka.

Izindiza kanye Nokuvikela

Ama-PTFE Backup Rings ayizingxenye ezibalulekile ezinhlelweni ze-hydraulic zezindiza, izimpahla zokufika, kanye nezinye izinhlelo zokusebenza ezisebenza kahle kakhulu. Amandla azo okubekezelela amazinga okushisa aphezulu kanye nokucindezeleka kuzenza zibe zilungele ukuqinisekisa ukuphepha nokuthembeka ezindaweni zezindiza.

Imboni Yezimoto

Ezinhlelweni zezimoto, ama-PTFE Backup Rings asetshenziswa ezinhlelweni zokudlulisa, amayunithi okuqondisa amandla, kanye nezinhlelo zamabhuleki ukuthuthukisa ukusebenza kokuvala kanye nokuqina. Ukungqubuzana kwawo okuphansi kanye nokumelana nokuguguleka kunegalelo ekuthuthukisweni kokusebenza kahle kanye nokunciphisa ukulungiswa.

Ukucutshungulwa Kokudla Nemithi

Ezimbonini lapho ukungcola kufanele kugwenywe khona, ama-PTFE Backup Rings aqinisekisa ukuthi izivalo zihlala zihlanzekile futhi azithinteki. Amazinga azo ahambisana ne-FDA abaluleke kakhulu ekusetshenzisweni okubandakanya ukudla, imithi, kanye namadivayisi ezokwelapha.

Kungani Kufanele Ukhethe Izindandatho Zokusekela ze-PTFE?

Ukusebenza Okuthuthukisiwe Kokuvala

Ama-PTFE Backup Rings anciphisa kakhulu ingozi yokukhishwa kwe-seal kanye nokuguqulwa kwayo, okuqinisekisa ukuthi ama-primary seal agcina ubuqotho bawo ngisho nangaphansi kwezimo ezimbi kakhulu. Lokhu kuholela ekusebenzeni okuthembekile nokungavuzi.

Ukuguquguquka Nokuqina

Ngenxa yobubanzi bawo bokushisa, ukumelana namakhemikhali, kanye namandla omshini, ama-PTFE Backup Rings afaneleka ezinhlotsheni eziningi zezicelo. Ukuqina kwawo kuqinisekisa impilo yesevisi ende kanye nezindleko zokulungisa ezincishisiwe.

Ukwenza Ngokwezifiso Nokutholakala

Ama-PTFE Backup Rings atholakala ngobukhulu obuhlukahlukene, izimo, kanye namazinga ezinto ezibonakalayo ukuze kuhlangatshezwane nezidingo ezithile zohlelo lokusebenza. Abakhiqizi abaningi banikeza nezixazululo ezenziwe ngokwezifiso ukubhekana nezinselele ezihlukile.

Isixazululo Esisebenza Kahle Ngezindleko

Nakuba i-PTFE iyinto esebenza kahle kakhulu, ukonga izindleko kusukela ekunakekelweni okuncishisiwe, impilo yesevisi ende, kanye nokusebenza kahle kohlelo okuthuthukisiwe kwenza i-PTFE Backup Rings ibe yisinqumo esingabizi kakhulu sezinhlelo zokusebenza ezidinga kakhulu.
