Uhura n'ubushyuhe bukabije, imiti, cyangwa ubushyuhe buke? Menya uburyo PTFE seal zikoreshwa mu mpeshyi (Variseal) zakora n'impamvu ari igisubizo cyizewe mu bikorwa bikomeye mu by'indege, imodoka, no mu nganda.
Intangiriro: Imipaka y'Ubuhanga bw'Ibipfukisho bya Elastomeric
Mu buhanga bukora neza, igice cyo gufunga akenshi ni cyo kintu cy'ingenzi kigena uburyo sisitemu yizewe. Nubwo imyenge isanzwe ya rubber nka O-rings ikora neza mu bikorwa byinshi, igera ku bushobozi bwayo iyo ihuye n'ubushyuhe bukabije, imiti ikaze, imikorere ihindagurika, cyangwa ibisabwa mu gushyushya buhoro. Ibi bibazo bisaba igisubizo gihuza imiterere y'ibikoresho bya polymeri zigezweho n'imbaraga zihoraho zo gufunga.
Iyi ni yo ngingo y’ikimenyetso gikoreshwa mu mpeshyi (kizwi cyane nka Variseal cyangwa Spring Seal). Iyi nkuru itanga ibisobanuro byimbitse ku buryo iyi kimenyetso ikora, ibibazo by’ingenzi ikemura, hamwe n’iby’ingenzi by’abahanga mu by’imiterere y’ikimenyetso bagaragaza ahantu hagoye gukorerwa ibintu.
1. Ihame ry'ingenzi: Ihuriro ry'Impeshyi na Polima
Ifu ikoresha ingufu z'impeshyi ni sisitemu y'ibice bibiri ikozwe neza cyane:
Ikoti rya Polymer: Ubusanzwe iminwa y'umupfundikizo ifite ishusho ya U ikozwe muri PTFE (Teflon®) cyangwa izindi polymer zikora neza nka PEEK cyangwa UHMWPE. Iri koti ritanga uburyo bwo gufunga bw'ibanze, rikoresha ubukana bw'ibinyabutabire, ubushyuhe bwinshi, hamwe n'uburyo bwo gukururana buri hasi cyane.
Isoko Itanga Ingufu: Isoko ikora nk'iy'icyuma gikozwe mu cyuma kitagira umugese cyangwa ibikoresho bikozwe mu buryo bworoshye nka Elgiloy®, iba mu gice cy'ikoti gifata U-channel.
Uburyo bwo gufunga bufite akamaro kanini:
1. Isoko itanga imbaraga zihoraho, zagenwe mbere, zisunika umunwa ufunga w'ikoti ku giti cyangwa ku rukuta rw'imyanya.
2. Iyo umuvuduko wa sisitemu ushyizwemo, ukora ku gipfundikizo, bikongera umuvuduko w'iminwa ku buso bwo guhuza. Ibi bitanga igipfundikizo cyizewe cyane kandi gikoresha umuvuduko.
3.Uruhare rw'ingenzi rw'impeshyi ni ugukemura ikibazo cyo kwangirika kw'ibikoresho no gukomeza gufunga nubwo hari imiterere idahwitse, ubushyuhe budasanzwe, cyangwa impinduka ziterwa n'ubushyuhe. Ibi bituma imikorere ihoraho mu gihe cyose cy'akazi k'impeshyi.
2. Imbogamizi z'ingenzi mu ikoreshwa ry'ibikoresho n'uburyo imyenge ikoreshwa mu mpeshyi ibikemura
Iri koranabuhanga ryagenewe gukemura ibibazo byihariye kandi bihenze by’ubuhanga:
Ikibazo: Ubushyuhe Bukabije n'Ubukonje bwa PTFE.
Ingero: Gufunga ibinyabutabire bihumanya nka azote y'amazi (-200°C) cyangwa ibinyabutabire bishyuha cyane (>200°C).
Umuti: PTFE igumana imiterere yayo mu bushyuhe bwinshi aho elastomer zinanirwa. Ariko, PTFE ikunze kugira "ubukonje" - guhinduka kw'amazi iyo idafite imbaraga nyinshi. Isoko ry'imbere rirwanya ubu bushyuhe, rigakomeza umuvuduko mwiza w'iminwa kandi rikarinda ko ipfundikanya ipfa uko igihe kigenda.
Ikibazo: Ibidukikije bya shimi cyangwa plasma bikaze.
Ingero: Gufunga ibintu bikomeye bya solvents, aside, bases, cyangwa ibikoresho bitunganya wafer bya semiconductor ukoresheje plasma yangiza.
Umuti: PTFE idafite imiti myinshi, itanga ubudahangarwa budasanzwe ku bintu byinshi birwanya imbaraga. Ibi bituma imisemburo ikoreshwa mu mpeshyi iba nziza mu gutunganya imiti, mu buvuzi no mu gukoresha imiti.
Ikibazo: Porogaramu zihinduka zifite amavuta make/adafite amavuta.
Ingero: Imigozi izunguruka yihuta cyane mu bikoresho byo mu rwego rwo hejuru, mu byumba by'isuku, cyangwa mu bikoresho aho amavuta adakenewe.
Umuti: Uburyo PTFE ikoresha amavuta karemano butuma izi seal zikora neza kandi zidasaza cyane, ndetse no mu gihe cyumye cyangwa kitarimo amavuta menshi. Ibi bigabanya ikoreshwa ry'amashanyarazi n'uburyo ubushyuhe bukoreshwa.
Ikibazo: Kwizerwa mu gihe kirekire hamwe no kubungabunga bike.
Ishusho: Ifunga ahantu hatagerwa cyangwa mu bikorwa aho igihe cyo kuruhuka kidateganijwe gihenze cyane.
Umuti: Imbaraga zihoraho z'impeshyi zigabanya kwangirika kw'iminwa, bigatuma agapapuro "kigenga ubwako." Ibi bivuze ko igihe cyo gukora cyagabanutse cyane kandi kongerera igihe hagati y'ibyangiritse (MTBF), bigabanya ikiguzi cyose cyo gutunga.
3. Igishushanyo mbonera cy'ingenzi n'uburyo bwo guhitamo ibikoresho kugira ngo bikore neza
Guhitamo agakoresho gakwiye gakoresha ingufu z'impeshyi si ibintu bisanzwe; bisaba gusuzuma witonze ibintu byinshi:
Ibikoresho by'ikoti:
Virgin PTFE: Igipimo ngenderwaho cy’ikoreshwa ry’ibinyabutabire n’ubushyuhe bwinshi.
PTFE yuzuye (urugero, irimo ikirahure, karuboni, grafiti, bronze): Ikoreshwa mu kongera ubushobozi bwo kudashira, kugabanya ubukonje, kongera ubushobozi bwo gutwara ubushyuhe, cyangwa kongera ubukana.
Izindi polymer (PEEK, UHMWPE): Zatoranijwe kubera ibikenewe byihariye nko gukomera cyane kwa mekanike (PEEK) cyangwa kudakomera cyane (UHMWPE).
Ubwoko bw'impeshyi n'ibikoresho:
Imbaraga z'impeshyi: Impeshyi zoroheje, ziciriritse, cyangwa ziremereye zitoranywa hashingiwe ku muvuduko, umuvuduko, n'ubushyuhe bukenewe.
Ibikoresho byo mu mpeshyi:
Icyuma kidashonga (302, 316): Kurwanya ingese muri rusange.
Elgiloy®/Hastelloy®: Ku bidukikije bigoye cyane bisaba ubudahangarwa budasanzwe ku mwobo, ubushyuhe bwinshi, n'amazi yangiza nk'amazi y'umunyu.
Imiterere y'ibumba: Igikombe cya U-cup gishobora kunozwa kugira ngo gikoreshwe mu buryo bwo kuzunguruka, buhindagurika, cyangwa butaziguye. Ibintu nk'inguni y'iminwa, uburebure bw'agatsinsino, n'ubugari bw'ikoti ni ingenzi kandi bigenwa neza iyo umuntu abigishije inama uruganda rubizi.
4. Itandukaniro mu nganda: Impamvu ubwiza ari ingenzi
Imikorere y’inyigo y’ikimenyetso gikoresha ingufu z’impeshyi igerwaho gusa binyuze mu kuba indashyikirwa mu nganda. Impeshyi zidakora neza cyangwa amakoti adakozwe neza bituma habaho kwangirika vuba. Inkingi z’ingenzi mu nganda zirimo:
Gutunganya neza amakoti: Ikoti rya PTFE rigomba kuba rikozwe mu buryo bunoze, ntabwo ari ugusohora gusa, kugira ngo rigere ku buremere bwiza kandi rigire ubuso bwiza ku munwa ufunga. Umunwa woroshye kandi uhoraho ni ingenzi kugira ngo habeho gucika intege no gufunga neza.
Ubudasa bw'impeshyi: Impeshyi igomba kuba ifatanye neza, kugira ngo imbaraga zikwirakwizwe neza mu ruziga rwose rw'igipfundikizo. Ubusumbane bw'impeshyi kuva ku rundi ruhande kugeza ku rundi ntibushobora kuganirwaho.
Igenzura ry’Ubuziranenge Rikomeye: Buri cyiciro cy’umusaruro kigomba kugenzurwa mu buryo bungana no kwemezwa n’ibikoresho. Gukurikirana kuva ku bikoresho fatizo kugeza ku bicuruzwa byarangiye bitanga icyizere cy’ubuziranenge n’uko byujuje ibisabwa (urugero: ROHS, REACH).
Umwanzuro: Kugaragaza Ikimenyetso Gikwiye cyo Kwizerwa Cyane
Ifuru zikoreshwa mu mpeshyi ni igisubizo cyizewe kandi cyizewe cyane ku bikorwa aho elastomer zisanzwe zidakora neza. Ubushobozi bwazo bwo gukora mu bihe bikomeye mu gihe zigabanya ikiguzi cyo kubungabunga igihe kirekire butuma ziba ishoramari ry’ubuhanga mu by’ubwubatsi.
Kugira ngo intsinzi igerweho ni ugusobanukirwa ibyo porogaramu isaba no gukorana n'umucuruzi utanga ubumenyi burambuye mu bijyanye n'ubumenyi bw'ibikoresho n'uburyo bwo gukora ibintu neza.
Witeguye gukemura ibibazo bikomeye byo gufunga?
Twandikire kugira ngo tuganire ku busabe bwawe.Itsinda ryacu rya tekiniki rishobora gutanga inama zishingiye ku makuru, imiterere yihariye, n'ingero kugira ngo umushinga wawe ugire icyo ugeraho.
