PTFE Inyuma-Impeta

Ibisobanuro bigufi:

Impeta zinyuma za PTFE ningingo zingenzi muri sisitemu yo gufunga umuvuduko ukabije, wagenewe gushimangira kashe yibanze nka O-impeta no gukumira ibicuruzwa biturutse ku mihangayiko ikabije. Yakozwe na polytetrafluoroethylene (PTFE), izo mpeta zigaragaza ubudahangarwa bw’imiti budasanzwe, zirwanya ibitangazamakuru hafi ya byose bikarishye birimo acide zikomeye, alkalis zikomeye, ibishishwa kama, na gaze yangiza. Coefficient ya ultra-low friction hamwe nuburinganire buhebuje butuma ibikorwa byizewe mubikorwa byingirakamaro hamwe nubushyuhe buri hagati ya -200 ° C na + 260 ° C. Imbaraga zo gukanda cyane hamwe nibiranga bidahinduka bituma igabanywa ryimitwaro myiza, ririnda neza kashe ya elastomerike kugirango itangirika cyangwa yangiritse mugihe ihindagurika ryumuvuduko. Hamwe nimiterere idasanzwe idafite inkoni hamwe na FDA / USP Icyiciro cya VI kubahiriza aho bikenewe, Impeta zinyuma za PTFE zikoreshwa cyane mubikorwa bikomeye nkibikoresho bya peteroli na gaze, ibikoresho bitunganya imiti, sisitemu ya hydraulic, hamwe n’imashini zikoresha imiti zisaba gukora nta bwandu. Guhuza imiti idahwitse hamwe nubushobozi bwo gukanika imashini bituma biba ngombwa kugirango bakomeze ubusugire bwa kashe mubidukikije bikora nabi.

Niki Impeta yinyuma ya PTFE

PTFE (Polytetrafluoroethylene) Impeta zimanikwa ningingo zingenzi muri sisitemu yo gufunga kashe, zagenewe cyane cyane gukumira no guhindagura kashe ya kashe yibanze mukibazo cyinshi kandi mubihe bikabije. Izi mpeta zitanga inkunga ikomeye kuri O-impeta nizindi kashe ya elastomeric, itanga igihe kirekire kandi yizewe mubisabwa mubikorwa byinganda.

Ibyingenzi byingenzi biranga impeta ya PTFE

Kurwanya Imiti idasanzwe

Impeta zo mu bwoko bwa PTFE zizwi cyane kubera ubudahangarwa bw’imiti, zitanga imiti itagereranywa y’imiti myinshi, harimo aside, ibishingwe, ibishishwa, n’ibicanwa. Ibi bituma biba byiza gukoreshwa mubidukikije byangirika cyane aho ibindi bikoresho byangirika.

Ikirere Cyinshi

PTFE irashobora gukora neza murwego rwubushyuhe bwagutse, kuva ubushyuhe bwa kirogenike kugeza hejuru ya 500 ° F (260 ° C). Iyi mpinduramatwara yemeza ko Impeta zinyuma za PTFE ziguma zikora kandi zizewe haba mubushyuhe bukabije nubukonje.

Coefficient nkeya yo guterana amagambo

PTFE ifite coefficente nkeya yo guterana, igabanya kwambara kubice byo guhuza kandi bikagabanya gutakaza ingufu. Uyu mutungo kandi ufasha mukugabanya ibyago byo guhitana no gufata, kwemeza imikorere myiza no mumitwaro myinshi.

Imbaraga Zikomeye

Impeta zinyuma za PTFE zakozwe kugirango zihangane ningutu zingirakamaro hamwe ningutu nyinshi. Ubwubatsi bwabo bukomeye burinda gusohora no guhindura ibintu, bityo bikazamura imikorere muri rusange no kuramba kwa sisitemu.

Kutanduza kandi FDA-Yubahiriza

PTFE ni ibikoresho bidahumanya, bituma bikenerwa mu bikorwa aho isuku n’isuku ari ngombwa, nko mu gutunganya ibiribwa, imiti, n’inganda zikoresha amashanyarazi. Impeta nyinshi za PTFE ziraboneka no mubyiciro bya FDA, byemeza ko byujuje ubuziranenge bukomeye.

Porogaramu ya PTFE Yibitse Impeta

Sisitemu ya Hydraulic na Pneumatic

Impeta zinyuma za PTFE zikoreshwa cyane muri silindiri ya hydraulic, actuator, na sisitemu ya pneumatike kugirango wirinde gusohora kashe no gukomeza ubusugire bwa kashe mugihe cyumuvuduko mwinshi. Ubuvanganzo buke no kwambara birwanya uruhare nabyo bigabanya kubungabunga no kuramba kwa serivisi.

Gutunganya imiti

Mu bimera byimiti, PTFE Backup Rings itanga inkunga yizewe kubidodo byatewe nimiti ikaze, acide, hamwe na solde. Imiti yimiti yabo itanga imikorere yigihe kirekire nta kwangirika.

Ikirere n'Ingabo

Impeta zinyuma za PTFE ningingo zingenzi muri sisitemu ya hydraulic yindege, ibikoresho byo kugwa, nibindi bikorwa bikora neza. Ubushobozi bwabo bwo guhangana nubushyuhe bukabije nigitutu bituma bakora neza mukurinda umutekano no kwizerwa mubidukikije.

Inganda zitwara ibinyabiziga

Muri porogaramu zikoresha amamodoka, Impeta zinyuma za PTFE zikoreshwa muri sisitemu yo kohereza, amashanyarazi, hamwe na sisitemu ya feri kugirango byongere imikorere yikimenyetso kandi biramba. Ubushotoranyi bwabo buke no kwambara birwanya uruhare mu kunoza imikorere no kugabanya kubungabunga.

Gutunganya ibiryo na farumasi

Mu nganda aho hagomba kwirindwa umwanda, Impeta zinyuma za PTFE zemeza ko kashe ikomeza kugira isuku kandi idakora. Amanota yabo yujuje FDA afite agaciro cyane mubikorwa birimo ibiryo, imiti, nibikoresho byubuvuzi.

Kuki Hitamo Impeta Zibitse za PTFE?

Kunoza imikorere ya kashe

Impeta zinyuma za PTFE zigabanya cyane ibyago byo gukuramo kashe no guhindura ibintu, byemeza ko kashe yibanze ikomeza ubusugire bwayo nubwo haba mubihe bikabije. Ibi biganisha kumikorere yizewe kandi idasohoka.

Guhindagurika no Kuramba

Nubushyuhe bwagutse buringaniye, imiti irwanya imiti, nimbaraga za mashini, Impeta zinyuma za PTFE zirakwiriye kumurongo mugari wa porogaramu. Kuramba kwabo bituma ubuzima bumara igihe kirekire no kugabanya amafaranga yo kubungabunga.

Guhitamo no kuboneka

Impeta zinyuma za PTFE ziraboneka mubunini butandukanye, imiterere, hamwe n amanota yibikoresho kugirango byuzuze ibisabwa byihariye. Ababikora benshi nabo batanga ibisubizo byihariye kugirango bakemure ibibazo byihariye.

Igisubizo Cyiza

Mugihe PTFE ari ibikoresho-bikora cyane, kuzigama ibiciro bivuye kugabanuka kubungabungwa, ubuzima bwa serivisi bwagutse, hamwe no kunoza imikorere ya sisitemu bituma PTFE Backup Rings ihitamo igiciro cyiza kubisabwa.
