Iyo ubajije ibikoresho bya gaze nziza kugirango birambye, uba umaze gutera ikirenge mucya kirombe cyo gusaba ibicuruzwa, ibicuruzwa bishaje, hamwe nubucuruzi nyabwo bwa siyanse yubucuruzi ituma abajenjeri barara nijoro. Ntabwo byoroshye nko gutoranya icyatsi-gisa nicyatsi; bijyanye nibitsinzwe neza, bimara igitutu nyacyo, kandi ntibitera akajagari gakomeye kubidukikije mugihe cyo kubyara cyangwa kujugunywa. Nabonye imishinga myinshi cyane aho gasike irambye yabaye ihuriro ridakomeye, biganisha kumeneka, kumanura, no gusetsa, imyanda myinshi. Reka duce urusaku.

Kurenga Icyatsi Cyatsi: Niki Kuramba Mubyukuri Bisobanura Igikuta

Mu murongo w'akazi, kuramba ntabwo ari inkoni gusa. Nibara ryubuzima. Ibikoresho birashobora gukorwa mubintu bitunganijwe neza, ariko niba bigabanutse mumezi atandatu mumurongo wimiti, urabisimbuza buri gihe-ibyo ntibiramba. Kuramba kwukuri kuringaniza kuramba, imikorere mubihe bikora (tekereza ubushyuhe, itangazamakuru, igitutu), ningaruka zanyuma yubuzima. Ndibuka umukiriya ushimangira kuri rebero runaka ya bio kumurongo wamazi ashyushye. Yagenzuye agasanduku gashobora kuvugururwa, ariko gusiganwa ku magare guhoraho byatumye gucika intege mu mwaka. Twabisimbuje hamwe na chimique yibanze cyane ya sintetike yamaze imyaka icumi. Ninde mubyukuri byari birambye? Uwo wasimbuye inshuro icumi, cyangwa uwo ushyiramo rimwe?

Ibi bituzanira ikibazo cyibanze: kuramba ninkingi yambere ya gasketi irambye. A. Ibikoresho bya Gasike ibyo birinda kumeneka umwanya muremure bigabanya ibyuka bihumanya ikirere, bikabika uburyo bwafunzwe (bwaba amazi, gaze, cyangwa imiti itunganijwe), kandi bikagabanya imikoreshereze yumutungo. Igicapo kirambye cyane nicyo wibagiwe kuko gikora gusa.

Noneho hariho ikirenge cyo gukora. Ingufu nubutunzi bukenewe kugirango habeho ibikoresho bibisi hanyuma ubigire urupapuro rwakoreshwa cyangwa rwuzuza ibikomere. Kurugero, isugi PTFE ifite ikirenge kinini cyumusaruro, ariko kutagira imbaraga no kuramba muri serivisi yangirika birashobora guhagarika ibyo mugihe runaka. Nukuringaniza kugoye nta gisubizo-kimwe-gisubizo-byose.

Ubusanzwe abakekwaho icyaha: Gufata neza-Ibikoresho

Reka tubone ibintu bifatika. Gucomeka Atari Asibesitosi (CNA) impapuro, nka fibre-ishimangirwa aramid cyangwa selile ivanze, ni urugo rwakazi. Nibyiza kubikorwa rusange, amazi, amavuta. Inguni zabo zirambye? Ntabwo ari asibesitosi (biragaragara, ibyingenzi), kandi amanota amwe akoresha fibre yongeye gukoreshwa. Ariko witondere ibisigarira bisigara - bimwe birashobora gutemba cyangwa kugabanya ubushyuhe bwubushyuhe. Nabakoresheje muri flanges yumuvuduko muke kumazi akonje nibisubizo byiza, ariko ntabwo nabishyira hafi yumuti ukomeye.

Igishushanyo cyagutse ni ikintu gishimishije. Nibyiza cyane kuri temps nyinshi, imiti myiza irwanya itangazamakuru ryinshi. Urebye kuramba, igishushanyo ni uburyo bwa karubone, ugereranije ni byinshi. Inzira yo kwaguka ni imbaraga nyinshi, nubwo. Intsinzi nini ni ukongera gukoreshwa - mubihe bimwe na bimwe, gasketi yakoreshejwe irashobora kongera gutunganywa. Nabonye zikoreshwa neza kuri flanges yubushyuhe munganda, zimara impinduka nyinshi. Ariko biroroshye mugihe cyo kwishyiriraho; ikintu kimwe kititaweho kandi ufite amarira, utera imyanda ako kanya.

Ibikoresho bishingiye kuri PTFE (isugi, yuzuye, yagutse) niyindi shyirahamwe. Imiti ya inert, ubugari bwagutse. Impaka zirambye hano zirakaze. Umusaruro wa Virgin PTFE urimo chimie ya PFAS, ni ibendera rikomeye ritukura kugirango ibidukikije bikomeze. Ariko, kuramba kwayo ntagereranywa kubora bimwe. Iterambere rishimishije cyane ryongeye gukoreshwa PTFE. Nashakishije gasketi zakozwe mubisubirwamo bya PTFE-igabanuka ryimikorere ni ntoya kubisabwa byinshi, kandi ikuraho imyanda mu myanda. Ni intambwe ihamye.

Elastomers nka EPDM cyangwa Nitrile. Niba ukeneye elastique no gufunga hejuru yuburinganire, ni abahatana. Amahitamo arambye hano arimo gukoresha ibishishwa bya reberi cyangwa bio-soko ya polymers. Ifatwa? Imiti nubushyuhe bwabo birakabije. Icyatsi cya EPDM gishobora kuba cyiza kuri sisitemu y'amazi meza ariko kizahinduka goo kumurongo wamavuta. Ugomba guhuza itangazamakuru neza.

Kwinjiza & Kubungabunga Ikarita Yishyamba

Dore ukuri gukunze kubura mumibare yamakuru: ibikoresho biramba cyane birashobora guhinduka imyanda mugushiraho nabi. Kurenza urugero-kumashanyarazi kumenagura gasketi mukuyoboka? Ibyo bishimangira flange, akenshi byangiza imiterere yimbere ya gasketi, kandi byemeza ubuzima bugufi. Munsi yumuriro? Kumeneka kuva kumunsi wambere. Imyitozo irambye irasobanutse neza, igenamigambi ikurikira inzira ikwiye nka ASME PCC-1. Nabaye ku mbuga aho bakoresheje gasike ihendutse, ikwiye ariko bakica iyinjizamo hamwe ningaruka zingaruka, biganisha kumeneka mugitangira no gufunga burundu kugirango bongere bongere. Gupfusha ubusa akazi, amasaha yo hasi, hamwe na gasike yashegeshwe kurenza kure ikiguzi cyibikoresho byashizweho neza.

Mu buryo nk'ubwo, kubungabunga filozofiya bifite akamaro. Igipapuro gifatwa nkigikoresho kimwe, cyo guta, cyangwa sisitemu yagenewe gusenywa neza kandi ishobora kongera gukoreshwa (kubwoko bumwe na bumwe bwakoreshwa nka gasketi zimwe zifunze)? Muri retrofit iheruka kubakiriya, twahinduye kuva kumpapuro zaciwe CNA tujya kuri gasketi yakomeretse hamwe na grafite yuzuza. Igiciro cyambere cyari kinini, ariko mugihe cyateganijwe guhinduka, barashobora gusa kongera gutwika gasketi yari isanzwe iyo igenzuwe ikabona amajwi. Ibyo byakijije ibikoresho n'umurimo.

Aha niho kugira umutanga wizewe wunvise ibyasabwe byose, ntabwo kugurisha urupapuro gusa, nibyingenzi. Umufatanyabikorwa nka Hamagara zitai yihuta ukora co., Ltd. (https://www.zitaifacens.com), ishingiye mubushinwa bukomeye bwihuta cyane, ibona ibi. Ntabwo ari umucuruzi wa gaseke gusa; bari mumutima wibidukikije byinganda. Kuba hafi yinzira nini zitwara abantu bivuze ko babona ibintu byinshi byukuri-byisi-byananiranye. Iyo muganiriye kumushinga hamwe nuwabikoze, uba ukoresheje ubwo burambe bufatika, kurwego rwo hasi kubyerekeranye nibiri mubyukuri, bimenyesha byimazeyo amahitamo arambye.

Ikiburanwa: Gusubiramo Amavuta Ashyushye Sisitemu

Reka ngende mu kazi runaka. Igihingwa cyatembye kuri 300 ° C sisitemu yo gukwirakwiza amavuta ashyushye. Bakoreshaga urupapuro rusanzwe rwa aramid. Cyakoze wenda amezi 8-12 mbere yo gukomera no kurira. Ibitonyanga bihoraho byari impanuka yumuriro hamwe n’amavuta, wongeyeho igihe cyo gusimbuza igihe cyarahenze.

Twabisesenguye. Ubushyuhe bwari hejuru yurugero rwa binder muri ibyo bikoresho bya CNA. Twasabye amahitamo abiri: premium, ubushyuhe bwo hejuru CNA hamwe na sisitemu ihamye ihamye, cyangwa gaze ya grafite yagutse. Igishushanyo cyari gifite igiciro cyo hejuru. Twakoresheje imibare: gushingira mubuzima buteganijwe bwa serivisi (grafite iteganijwe imyaka 3-5 nu mwaka 1 kuri premium CNA), kugabanya ibyago byo guhagarara bitateganijwe, hamwe nigikorwa cyogukora isuku (nta binder yo guteka), igishushanyo cyari amahitamo arambye kandi yubukungu mugihe cyimyaka 5.

Umukinnyi? Kwinjiza. Tugomba guhugura abakozi babashinzwe kubungabunga impapuro zoroshye, zoroshye. Nta gukata kuri flange, guhuza neza, hamwe nibisanzwe, byinshi-bitambutse bikurikiranye. Byatwaye igihe kinini mugushiraho kwambere. Ariko byarakomeje. Nyuma yimyaka itatu mugenzuzi ryateganijwe, gasketi yari ikiri muri spec. Nibyo biramba ushobora gupima: zeru zeru, gusimbuza zeru, imyanda ya zeru ikomoka kuri sisitemu mumyaka itatu.

None, Niki Cyiza? Ni Igisubizo gikubiyemo

Urabona, nta bikoresho byiza byiza. Igicapo cyiza kirambye nicyo gihuza neza na serivisi yacyo, gishyirwaho neza, kandi kiva mubuzima bwuzuye mubitekerezo. Ku muyoboro w'amazi ufite umuvuduko muke, CNA irimo ibiyikubiyemo bishobora kuba intandaro yo kuramba. Kuri serivisi ya acide yibasiwe, iramba, yimiti ya PTFE (cyangwa nziza, ikoreshwa neza PTFE) imara imyaka mirongo irashobora guhitamo icyatsi kibisi.

Inama nakugira? Ubwa mbere, sobanura ibipimo byawe bikora ubugome - itangazamakuru, kwibanda, ubushyuhe, igitutu, gusiganwa ku magare. Icya kabiri, shyira imbere kuramba no kudakora neza kuruta byose. Ikidodo kirekire kirambye ntigisanzwe. Icya gatatu, shakisha uburyo bukoreshwa muburyo butandukanye (nka PTFE cyangwa reberi isubirwamo) kugirango usabe - ikoranabuhanga riratera imbere. Hanyuma, fata iyinjizamo nkigice cyibikoresho. Igikuta cyiza cyangijwe nigituba ni imyanda 100%.

Nicyemezo gifatika, kijyanye nubuhanga bwubuhanga, ntabwo ari agasanduku. Ninimpamvu ibiganiro nababikora bafite ubumenyi bwimbitse bwo gusaba, nkibyo kuri Handan Zitai Yihuta, ni ingirakamaro. Ziherereye muri Yongnian, zibona ibyifuzo byananiranye bituruka mu nganda zitabarika, zibaha ibitekerezo bifatika, bidafite ishingiro kubyerekeranye nibikoresho bitanga imikorere irambye kwisi. Nubwoko bwubushishozi bukurenga kurutonde rwibisobanuro kandi mubyukuri byizewe, bigabanijwe-bigabanya imyanda.
