Ikoreshwa ryiza rya nitrile rubber gaskets? 

Noneho, urimo kwibaza kuri Tuvugishije ukuri, abantu benshi batekereza gusa kwihanganira amavuta bagahagarara aho. Ngiyo intangiriro ihamye, ariko irabura nuance. Mubikorwa, agaciro nyako ka NBR kari muburinganire bwacyo-gushiraho neza, guhagarika neza abrasion, hamwe no kurwanya amavuta, lisansi, hamwe n’imiti myinshi, byose ku giciro kidasenya banki. Nibikorwa byakazi, ntabwo byerekana pony. Amayeri ni ukumenya aho iyo mpirimbanyi ikorera n'aho itangirira gutandukana.

Aho NBR Yerekana Mubyukuri: Ahantu heza

Kubwanjye, ibyakera, nta-bwonko bukoreshwa biri muri sisitemu ya lisansi yimodoka. Turimo tuvuga modul ya pompe ya moderi, twohereza kashe yibice, gaze ya karbureti (kuri moteri ishaje, birumvikana), na O-impeta zitandukanye kumurongo. Urufunguzo hano ni uguhora uhura na lisansi na mazutu, akenshi hamwe ninyongeramusaruro zigezweho. Urwego rusanzwe rwa NBR, vuga hamwe na acrylonitrile yo hagati (ACN), ikemura neza. Nabonye bimara imyaka muribi bidukikije aho ubushyuhe budakunze kurenga 100 ° C. Birahanurwa.

Noneho hariho hydraulics rusange yinganda. Ntabwo sisitemu ikora cyane, irwanya umuriro wa fosifate ester-ibyo ni inyamaswa itandukanye - ariko sisitemu yawe isanzwe ishingiye kumavuta ya hydraulic mumashini. Igipapuro kiri hejuru ya valve, ibigega byamazi, hamwe numuyoboro muke. Barimo kwikuramo buri gihe kandi boga mumavuta. Igikoresho cya NBR cyateguwe neza hano gitanga kashe yizewe, ndende. Uburyo bwo kunanirwa mubusanzwe bugenda bukomera buhoro buhoro mumyaka myinshi, ntabwo bitunguranye bitunguranye, aribyo ushaka kugirango gahunda yo kubungabunga ibe.

Ahandi hantu hakunze kwirengagizwa ni ibikoresho byo gukaraba mugutunganya ibiryo. Noneho, nyumva-NBR ntabwo isanzwe-urwego rwibiryo keretse niba byujujwe kandi byemewe. Ariko kubidodo byo hanze kumazu ya pompe, gushira gasketi kubikoresho byatewe namazi ashyushye, isuku ya caustic, hamwe nisuku yoroheje, ni nyampinga uhenze cyane. Irwanya kubyimba no gutesha agaciro byica gaseke ya EPDM isanzwe muri iyo supu yimiti. Ugomba kumenya neza rwose ko bidahuye neza nibicuruzwa bitemba.

Imipaka na hafi ya Scenarios

Aha niho uburambe bugutwara amafaranga, mubisanzwe wirinda ikosa. Umutego munini ni ubushyuhe. Umubare ntarengwa wa NBR wemewe muri rusange nka 100-120 ° C ikomeza. Shyira kuri 135 ° C, kandi igihe cyo kubaho kiragabanuka. Nize ibi inzira igoye kumurongo wo gusohora compressor. Ibisobanuro byavugaga amavuta, bityo twakoresheje NBR. Cyakoze… amezi agera kuri atandatu mbere yuko gitekwa mu kajagari. Ubushyuhe bwo gusohora rimwe na rimwe bwagendaga burenga imipaka. Ako kazi gakeneye gaseke ya FKM (Viton). NBR ni ubushyuhe buke.

Ozone nikirere nikindi kintu kidakomeye. Niba gaze igiye guhura nizuba ryumuyaga numwuka wo hanze, cyane cyane ibikoresho byamashanyarazi bishobora kubyara ozone, NBR izacika. Ntabwo ari ibikoresho byo hanze. Nabonye bibaho kuri hydraulic fitingi yo hanze kubikoresho bigendanwa byicaye igihe kirekire. Ikidodo cyasaga neza kugeza ubikozeho kirasenyuka. Kuri ibyo bihe, wagarutse kuri EPDM cyangwa uruganda rudasanzwe.

Noneho hariho imiti ihuza hydrocarbone. Ketone, esters, acide ikomeye, feri ya feri (DOT 3, 4, 5.1) - ibi bizatera NBR isanzwe. Hariho imyumvire itari yo ivuga ko kurwanya amavuta bisobanura imiti irwanya imiti. Ntabwo aribyo. Burigihe, burigihe kugenzura imbonerahamwe ihuza amazi yihariye. Utanga isoko hamwe nubumenyi bwimbitse nubumenyi bwa tekinike ni ngombwa hano. Kurugero, isosiyete nka Hamagara zitai yihuta ukora co., Ltd., ikorera mu Bushinwa bunini busanzwe igice cya Yongnian, akenshi itwara amanota atandukanye. Mugihe kizwiho gufunga, benshi mubakora inganda zishyizwe hamwe nabo batanga cyangwa barashobora gutanga inama kubintu bikwiye byo gufunga inteko, bakumva ko bolt na gaze bigomba gukora nka sisitemu. Aho biherereye hafi yinzira nini zitwara abantu nka gari ya moshi ya Beijing-Guangzhou bivuze ko bakunze gushakisha cyangwa gutanga ibikoresho kubintu byinshi byinganda zikoreshwa mu nganda, bityo bakabona icyakora nikitagenda neza mumurima.

Ibyiciro by'ibikoresho na Sekibi murambuye

Ntabwo NBR yose yaremewe kimwe. Ibirimo acrylonitrile nibyo byingenzi. ACN yo hejuru itanga amavuta meza / lisansi ariko kubiciro byubushyuhe buke. Kuri gaze muri sisitemu ya hydraulic yuburayi bwamajyaruguru ibona -20 ° C, ACN NBR irashobora kuba ikomeye cyane kuburyo idashobora gufunga neza mugitangira. Wakenera kuvanga-ACN nkeya. Nubucuruzi.

Noneho hariho guteranya-kuzuza, plastiseri, hamwe na sisitemu yo gukiza. Igicapo cya kashe ifite imbaraga (nka kashe ya shaft) ikenera ibintu bitandukanye byo kurwanya abrasion hamwe na compression yashizwemo kuruta gaze ya static flange. Utanga isoko neza azabaza kubyerekeye gusaba: static cyangwa dinamike? Ubushyuhe bukomeje? Itangazamakuru ryuzuye? Umukazo? Ibisubizo byerekana ibice. Igiciro cyahendutse, rusange NBR gishobora gufunga muburyo bwambere ariko bikananirana imburagihe kuko bitagenewe guhangayika byihariye.

Ndibuka umushinga urimo gufunga sisitemu yo kuvanga biodiesel. Bisanzwe NBR yananiwe vuba. Ikibazo ntabwo cyari lisansi shingiro, ahubwo yibanze cyane kuri esters hamwe nubushobozi bwinyongera ziyongera mubivange. Twahindukiye kuri gaze ya hydrogène nitrile (HNBR), ifite imiti myinshi irwanya imiti nubushyuhe, maze ikibazo kirashira. Isomo kwari ukureba ibirenze izina ryamazi rusange kubintu bifatika, bigezweho.

Gushyira mu bikorwa no Kwubaka Ubwenge

Ndetse gaseke nziza irananirana niba yashizwemo nabi. NBR ifite compressible nziza, ariko ntabwo ibabarira bitagira akagero. Ubuso bwa flange burangiza ibintu. Birakabije, kandi bizacamo ibikoresho munsi yumutwaro. Biroroshye cyane (nkindorerwamo irangiza), kandi ntishobora kuba ifite kurumwa bihagije kugirango irinde kunyerera. Kurangiza neza cyangwa microinch 60-90 mubisanzwe ni ahantu heza.

Bolt torque hamwe nurutonde birakomeye. Ukeneye ndetse na compression kugirango utembe ibikoresho bya gaze gato mubitunganye bya flange. Kumenagura cyane, kandi uzakuramo reberi cyangwa uteze impagarara nyinshi kuburyo byihuta gusaza. Munsi ya torque, kandi izatemba. Buri gihe ukurikize OEM torque igaragara niba ihari. Niba atari byo, itegeko rusange kubisanzwe reberi ya nitrile kumurongo wicyuma nugushira kumurongo hagati yubunini bwa bolt hamwe nicyiciro, hanyuma ukongera kugenzura nyuma yubushyuhe.

Ububiko nikindi kintu cyoroshye abantu bitiranya. Ntugasige gaseke ya NBR mumasanduku ashyushye yizuba ryinshi, cyangwa urundarunda munsi yicyuma kiremereye. Bazafata seti, babone ozone, cyangwa byangiritse. Ubike mubipfunyika byumwimerere, ahantu hakonje, hijimye, humye. Ibintu by'ibanze, ariko watungurwa.

Igihe cyo Kureba Ahandi: Ibindi

None ni ryari utererana NBR? Ndangije kubimenyesha: ubushyuhe bukabije bukomeza (hejuru ya 120 ° C), guhura na ozone / ikirere, hamwe n’imiti ikaze hanze yumuryango wa hydrocarubone. Kujya mubindi bisobanuro noneho bigahinduka:

Icyemezo burigihe kiza kumazi yihariye, ubushyuhe, umuvuduko, nigiciro. Nta gaseke nziza yisi yose. Kubice byinshi byinganda zikoreshwa mu nganda n’imodoka zirimo peteroli ishingiye kuri peteroli ku bushyuhe buke, nitrile rubber gaskets guma usanzwe, guhitamo pragmatic. Imikoreshereze yabo myiza iri muribintu bitabarika, bidashimishije aho kwizerwa no gukoresha neza ibintu birenze imikorere idasanzwe. Ugomba kumenya imipaka, no kuyubaha.
