Ibyiza bya 0-Impeta

Iyo ibice bimwe bya 0-impeta yabuze, kandi igipimo cya kashe kizwi mugihe ibice bitabonetse, 0-ring kits dimension areal kuko itanga guhitamo ibice hamwe nubunini bwa O-impeta kubikorwa bitandukanye.

Ibikoresho 0-impeta bikozwe muburyo buhanitse kandi bwa nitrile reberi iramba 0-ings. Impeta zitunganijwe neza mumasanduku yo kubika neza.

Ibikoresho 0-impeta ni inganda zisanzwe, kandi zifite hejuru hejuru yikingirizo, zirimo ibisobanuro birambuye, nubunini bwa kashe ya 0-impeta muri buri gice.

Ibikoresho 0-impeta bitangwa muri reberi ya nitrile kubera ko abantu benshi bakoresha ibikoresho mugihe mumazi yumunyu, ozone ibafasha mugutera NBR. Kubwibyo, Viton na NBR oring agasanduku bakoresheje intoki mukumena ubukana bwa nitrile.

Agasanduku ka Viton ningirakamaro mugusana robine kubera NBR, kandi impeta ya kits ft valves zitandukanye ikora cyane cyane moderi ikunzwe.

0-impeta ifite akamaro mukugabanya amafaranga yo kubungabunga kimwe nabakozi binteko mugukuraho gukeka muguhitamo iki gihe cyo kuzigama.

0-impeta itanga ibyoroshye kandi byoroshye kuyikoresha, bityo ikaba nziza kubisabwa no gukomeza.

Ibisobanuro

Impeta yo gufunga (impeta ya ptfe) ikomatanya ibintu bya elastique hamwe na kashe ya reberi hamwe n’imiti ya Teflon. Ikozwe muri silicone cyangwa Viton rubber (fluororubber) imbere yimbere kandi ugereranije na Teflon FeP (polyperfluorinated Ethylene propylene) cyangwa Teflon Pfa (soluble polytetrafluoron) ikomatanyirijwe hamwe, iyi mpeta ya reberi TEflon itanga imikorere myiza yo gufunga.

Rubber O-impeta byoroshye kwambara, imiti irwanya ruswa hamwe na gaze irwanya gaze irakennye, ubukana bwa O-impeta irakomeye kugirango irwanye kwikuramo ariko elastique idahwitse. Teflon FeP / TeFLon PFA O-impeta zifite imbaraga zo gukomera no gutuza imiti (keretse iyo byibasiwe nicyuma cya alkali, fluorine hamwe na halide imwe mubushyuhe bwinshi) kandi ifite elastique nziza hafi ya reberi O-impeta, FeP / TeFLon PFA ifite coefficient nkeya cyane ya guterana amagambo (0.1 kugeza 0.2 gusa) hamwe no guhangana cyane na gaze ya gaze, ituma kashe mpeta yometseho ikwiriye gukoreshwa nabi. Kubwibyo, ptfe yatwikiriye O-impeta, aho kuba reberi ihenze ya PERfluorinated O-ring.

Imikorere

Ubuso bwubusa kandi busa bwa teFLon FEP / TEFLon PFA hamwe na reberi yimbere bituma impeta yose ifunga kugirango igumane kashe imwe, elastike no kwikuramo buri ngingo kumyenda yimpeta, irashobora gushyirwaho inshuro nyinshi mugikorwa cyo gukomeza igitutu. Hamwe no kwiyongera k'umuvuduko wo hagati, impeta yo gufunga irahagarikwa muri rusange. Impeta yo gufunga ni nkamazi maremare yijimye, kandi umuvuduko uyikoraho woherezwa mubyerekezo byose nta kugabanya.

Ibikoresho

Teflon FEP na Teflon PFA birasa cyane, ariko teflon PFA ifite ubushyuhe bwo hejuru kurenza Teflon FEP

Impeta ikomeye yo gufunga impeta ni *, umubare munini wibisabwa hamwe na kashe ihamye hamwe na kashe ya dinamike. Ububiko bwa silicone reberi yometseho impeta ya diametre muri rusange ni nini, ikoreshwa mukidodo gihamye, ubukana bwayo hamwe no kwikomeretsa biri munsi yimpeta zifunze impeta.

Kwikuramo

Kubaho kwa feP yo hanze ituma impeta yo gufunga ifite imbaraga zo gukomera no kurwanya ubukana, kandi intangiriro yimbere ikozwe muri silicone reberi cyangwa reberi ya Viton ituma impeta yikidodo ikomeza kugumya gukomera munsi yubushyuhe bwo hejuru bwa 205 ℃. Kugereranya imikorere yikigereranyo cya kalrez rubber (perfluoroether rubber), Viton reberi na feP yometseho impeta mugikoresho cyo guhunika cyerekanwe kumashusho: Ibisubizo byikizamini byerekana ko imiterere yumubiri wa rubber silicone cyangwa Viton rubber na Teflon FeP / TeFLon Imiterere yimiti ya PFA ihujwe no gukora impeta yikingira impeta, ifite compressible nziza mugihe ikomeza reberi. Ikidodo c'impeta gikozwe neza gikozwe neza hamwe no kugenzura ubuziranenge hifashishijwe uburyo budasanzwe aho polimeri ya Teflon FeP iba ​​yuzuye neza muri reberi yimbere kandi O-impeta ikorwa muburyo bwo kwihanganira bisanzwe. Amakuru yakoreshejwe yerekana ko dufite ubwitange bwiza kubicuruzwa byacu byambarwa, bishingiye ku gupima imikorere no kugenzura byimazeyo kugirango abakiriya banyuzwe kandi bakoreshe neza ibicuruzwa. Ugereranije nibindi bikoresho byose bya reberi cyangwa TEFlon o-impeta, impeta yo gufunga ifite kashe ntagereranywa hamwe nubuzima burebure, cyane cyane mubitangazamakuru bikaze.

Kurwanya Kurwanya Imiti

Teflon FEP / Teflon PFA nigice cyibanze cyimpeta. Ifite imbaraga zo kurwanya isuri. Ku bushyuhe busanzwe bwa serivisi, Teflon FeP / Teflon PFA yibasiwe n’imiti mike, kandi imiti idahuye gusa hano. Kurugero, ibyuma bimwe bikomeye, fluorine hamwe na halide bimwe ntibishobora kubangikanya na Teflon FeP / Teflon PFA.

Iyo ihuye na Teflon FeP (ubushyuhe ntarengwa busabwa: 204 ℃ / 400F) / Teflon PFA (hasabwa ubushyuhe ntarengwa: 260 ℃ / 500F), imiti imwe nimwe yibitekerezo byinshi izabyitwaramo. Ku bushyuhe bwinshi, Teflon FeP / Teflon PFA yangizwa n’ibintu kama birimo 80% NaOH na KOH, hydride yicyuma nka acide boric (B2 H6), chloride ya aluminium, ammonia (NH3) na acide amine (NH2) na imino (R) = NH). Muburyo bwa 80f, okiside idakira ya 70% acide nitric nayo irashobora kuba 80f.

Niba ikoreshwa muribi bihe, ibicuruzwa bigomba kugeragezwa bidasanzwe. Usibye imiti yavuzwe, impeta yo gutwikira ubusanzwe iba yinjije imiti yindi miti.

Amabwiriza yo kwishyiriraho impeta yo gufunga impeta

1.

2. Koresha amavuta yoroheje cyangwa amavuta meza kugirango usige hejuru yimpeta yikimenyetso hamwe nuguhuza nibice bijyanye.

3. Niba impeta yo gufunga impeta itwikiriye bigoye kuyishyira ku rufunzo, irashobora kwibizwa mumazi ashyushye muminota mike kugirango yongere. Kworoshya no kwaguka O-impeta byoroshye gushira. Shyiramo O-impeta mugihe ishyushye hanyuma usubire mubunini bwayo iyo ikonje.

4. Ntugapfukame o-impeta yimpeta yambaye cyane, bitabaye ibyo bizatera inkeke ya teflon kandi bigira ingaruka kumikoreshereze.

Gusabwa gukenera impeta ya kashe nuburyo bukurikira

Ikirango gihamye: 15% -20%

Ikimenyetso kidasanzwe: 10% -12%

Indwara y'umusonga: 7% -8%

Igice cyambukiranya

Igice cya O gifunze impeta impeta yikimenyetso nigicuruzwa gisanzwe, birumvikana ko gishobora no gukora impande enye zingana nu mpande enye zometseho impeta zifunga impeta, iyi mpeta yo gufunga ikoreshwa hejuru yikimenyetso kinini kandi irashobora kwihanganira igitutu kinini, hamwe nubunini bwayo. Birashobora gukorwa hamwe na o-shusho igice cyometseho impeta impeta imwe, ariko bisaba kwikuramo hasi.

Ikimenyetso cya O-kashe yerekana impeta irasanzwe cyane, kare cyangwa urukiramende igice cyometseho impeta zikoreshwa mubihe bimwe byihariye, nyamuneka hamagara isosiyete yacu cyangwa abadandaza mbere yo gutumiza no kugisha inama.

Igice cy'urukiramende rw'impeta yometseho impeta yateguwe hakurikijwe imiterere ya nomero yubuso bwa nyuma bwo gufunga igifuniko, iki gipapuro gifunga kashe cyitwa impeta y'urukiramende, impeta yo hanze yashizwemo na teFLon FEP / PFA ibisobanuro bitandukanye na diametero zifunze Urukiramende rufunga impeta yubunini bwuruhererekane nimpeta yatwikiriye nayo iruzuye.
