Imbaraga nyinshi za gasketi ziramba? 

Iyo wunvise imbaraga nyinshi gasketi yumukara, niki kiza mubitekerezo? Benshi bahita batekereza ibara - iyo matte cyangwa rimwe na rimwe irabagirana gato umukara urangije - bakayigereranya nibikorwa byiza. Ariko uwo ni umutego wambere. Ibara ni uburyo bwo kuvura hejuru, akenshi fosifate cyangwa oxyde ya oxyde, rimwe na rimwe igifuniko cya elastomerique kashe yihariye. Ikibazo nyacyo kiramba ntabwo kijyanye nibara rifashe; ni bijyanye no kumenya niba imbaraga nyinshi ibikoresho byingenzi, bifatanije nubuso, birashobora kwihanganira ibidukikije byajugunywe. Nabonye imishinga myinshi aho itsinda ryerekanaga gasketi yumukara kugirango flange yumuvuduko ukabije, ikururwa nigitsure gikomeye, gusa guhura nikibazo cyo kunanirwa imburagihe kuko bibanze kuburanga aho kwibanda kubintu hamwe na serivise.

Intangiriro Inyuma

Reka twiyambure inyuma. Imbaraga zo hejuru mubisanzwe zerekeza kumurongo wibyuma. Dukunze kuvuga ibyuma byamasoko (nka 301/304/316 bitagira umwanda), ibyuma bya karubone, cyangwa rimwe na rimwe umuringa-nikel. Igikorwa cyo kwirabura, nka fosifike ya zinc itwikiriye ibyuma bya karubone, cyane cyane itanga ruswa irwanya ruswa hamwe nubuso buke bwo hejuru kugirango ifate neza. Ntabwo mu buryo bw'amayobera ihindura ibikoresho byo mu rwego rwo hasi muburyo bukomeye. Imbaraga zituruka ku bushyuhe bw'icyuma n'ubunini. Igenzura risanzwe ryerekana ubugari utitaye kugabana imitwaro. Uburebure bwa 1.5mm, bwirabura 304SS bushobora kureba igice, ariko munsi yumutwaro muremure mumurongo utaringaniye, urashobora gutanga cyangwa kunyerera, gutakaza imbaraga za kashe. Igipfukisho c'umukara kirashobora kuba kitameze neza, gitanga umutekano mubi mugihe kashe yananiwe.

Ndibuka urubanza kuri retrofit yubushyuhe. Umukiriya yashimangiye ko umukara wa oxyde wirabura usize icyuma cya karuboni icyuma gikomeretsa umurongo w’umuriro ushushe, avuga ko byakoreshejwe neza mu murongo w’amazi. Ubushyuhe bwo gusiganwa ku magare hamwe na kondine ya shimi muri serivisi ya parike byibasiye icyuma cya karubone munsi yacyo. Igifuniko ubwacyo cyarafashe, ariko twasanze ihungabana ryangirika mu byuma nyuma y'amezi umunani gusa. Kuramba hejuru yumukara byari byuzuye umutuku. Twahinduye kuri grafite yuzuye, yuzuye umukara 316L igikomere cyizunguruka, cyakemutse. Isomo? Ibidukikije - ubushyuhe, itangazamakuru, pH, umuvuduko wamagare - utegeka ibintu byingenzi. Ibara ni impanuka.

Indi nuance nuburinganire bwonyine. Ntabwo imyenda yose yirabura iringana. Igifuniko gihenze, cyoroshye cya fosifate kirashobora gushira mugihe cyo kwishyiriraho cyangwa kuva muri flange ntoya, bikerekana ibyuma byambaye ubusa. Igikoresho kinini cyirabura cya elastomer, nka fluoroelastomer, yongera imiti irwanya imiti ariko irashobora kugabanuka. Ugomba kumenya ibyo ugura. Nkunze kubaza abatanga urupapuro rwerekana - ni kuri ASTM A380 kubitagira umwanda? Ni polymer yihariye? Niba badashobora kuyitanga, iryo ni ibendera ritukura.

Umuvuduko, Ubushyuhe, na Squeeze

Kuramba munsi yumutwaro niho ibitekerezo bihura na gride. A. gasketi ntabwo ari ibintu byoroshye; ni ikintu cyabugenewe kigomba gutemba munsi yumutwaro wa bolt kugirango wuzuze ubusembwa bwa flange, hanyuma ukomeze gukira byoroshye kugirango ugumane kashe nkuko sisitemu ishyuha kandi ningutu zihindagurika. Igifuniko cyirabura kigira ingaruka kuri coefficient de frais. Ubushotoranyi buhanitse (butwikiriye umukara butanga) burashobora kuba bwiza mukurwanya umuyaga ariko birashobora gusaba umuriro mwinshi kugirango ugere kubwikubitiro bwambere. Niba itara ridahinduwe, urashobora munsi-compress, biganisha kumeneka kuva kumunsi wambere.

Twanyarukiye muriyi kumurongo wo gusohora compressor. Ukoresheje isoko rishya ryumukara wijimye wijimye wijimye, feri yakoresheje indangagaciro zabo zisanzwe. Ikizamini cya hydro cyambere cyatsinzwe, ariko mubikorwa, hamwe nu gusiganwa ku magare yumuriro, twabonye gutemba. Nyuma yo gusenywa, gasketi yerekanaga ikirenge kituzuye - igifuniko nticyari cyimuriwe mumaso ya flange, byerekana ko kitigeze gifunga neza. Igifuniko cyari kinini kandi gifata kurusha uwatanze isoko mbere. Tugomba guhonda torque hafi 15% kubunini bumwe. Nibintu bito, ariko byishe Uwiteka kuramba y'ibyo kwishyiriraho kugeza tubimenye.

Ubushyuhe nubundi bwicanyi. Ipfunyika nziza yumukara hejuru yicyuma gisanzwe cya karubone irashobora kuba nziza kugeza kuri 500 ° F, ariko hejuru yibyo, irashobora gutesha agaciro, gutwika, cyangwa gucumura. Nabonye impuzu z'umukara zihinduka ifu ya poweri mubushyuhe bwinshi, hasigara icyuma cyerekanwe. Kuri serivisi zohejuru cyane, urareba amarangi yihariye yubushyuhe bwo hejuru cyangwa, mubisanzwe, ukemera ko igifuniko kizashya kandi ukishingikiriza ku bushyuhe bwo hejuru bwa okiside yo mu cyuma ubwacyo, nko gukoresha 321SS cyangwa Inconel. Umukara muribi bihe akenshi ni ukumenyekanisha kwambere no kwirinda ingese mububiko, ntabwo kubikorwa bya serivisi.

Kunanirwa kwukuri-kwisi nicyo bigisha

Ntakintu cyigisha nko gutsindwa. Ndibuka icyiciro cya black-oxyde yatwikiriye impeta ya gasketi yo gutunganya imiti myinshi. Ibikoresho byari byiza (316SS), igipimo cyumuvuduko cyari cyiza. Bananiwe mu byumweru hamwe no gutobora munsi yigitambaro. Intandaro? Chloride mumigezi. Umwijima wa okiside wirabura utagira umwanda, nubwo ari mwiza mukurwanya ruswa muri rusange, urashobora rimwe na rimwe gutera imiterere ya crevice niba idashyizwe mubikorwa neza. Chloride yafatiwe muri micro-crevices ya coating yatumye habaho gutobora no kwangirika kwangirika kwangirika munsi. Igifuniko cyagize uruhare mu kunanirwa. Twahindukiye mu kibaya, cyatoraguwe kandi gishiramo gaze ya 316SS idafite igifuniko, maze ikibazo kirashira. Rimwe na rimwe, kurangiza biramba cyane ntabwo ari kurangiza na gato.

Ubundi buryo bwa kera ni ruswa ya galvanic. Icyuma gikozwe mu cyuma cya karubone icyuma gikoreshwa hagati yibyuma bibiri bidafite ingese. Ipitingi irashushanya mugihe cyo kwishyiriraho umwobo cyangwa impande. Noneho ufite anode ntoya (ibyuma bya karubone) ikora kuri cathode nini (idafite umwanda), mubidukikije. Ibyuma bya karubone byangirika vuba, bikarya igice cyikoreza imitwaro. Igifuniko cyirabura gisa neza hejuru ya 90% yubuso, ariko gasketi irabangamiwe kumpande zikomeye. Niyo mpanvu guhuza ibintu ari intambwe yambere idashobora kuganirwaho, cyane cyane kuruta ibara ryubuso.

Inararibonye zinteye gushidikanya cyane kurutonde urwo arirwo rwose rwerekana gasike yumukara nkibintu byingenzi. Ibisobanuro nyabyo - ASME B16.20, B16.21, ibikoresho bifatika (nko kuva mubukora bizwi nka Hamagara zitai yihuta ukora co., Ltd.. Urubuga https://www.zitaifacens.com Urashobora gutondekanya ibicuruzwa byabo, ariko ikiganiro nyacyo gitangira iyo ubajije raporo yikizamini inyuma yibyo gasket yumukara Urutonde.

Kwishyiriraho - Akanya k'ukuri

Kuramba nabyo byahimbwe mugihe cyo kwishyiriraho. Igipapuro cyirabura cyirabura kirashobora kwibasirwa cyane no gukemura ibyangiritse. Kujugunya hasi ya beto birashobora gukata igifuniko. Gukoresha icyuma cyogosha kugirango usukure flange ishaje hanyuma ushyireho gaze nshya irashobora gushiramo uduce duto duto duto duto. Buri gihe nshimangira kubiganza bisukuye, bifashe neza hamwe nahantu hateganijwe. Igifuniko ni umurongo wambere wo kwirwanaho; kumena mugihe cyo kwishyiriraho ni nko gusiga uruzitiro umaze gutema inkwi.

Gusiga amavuta ni indi ngingo. Ugomba gusiga amavuta yuzuye umukara? Muri rusange, oya. Igipfundikizo akenshi cyagenewe guterana amagambo. Ongeramo amavuta adashobora kubangikanya birashobora gusenya igifuniko cyangwa gukora ahantu hanyerera bitera gasketi gusohoka mukibazo. Isura ya flange igomba kuba ifite isuku kandi yumutse keretse uwakoze gasketi asabye cyane cyane kurwanya-gufata (mubisanzwe kubwoko bumwe na bumwe bwa grafite cyangwa PTFE). Aka ni akandi gace ukeka ko gasketi zose zirabura ari zimwe zitera ibibazo.

Kubona igitutu cya mbere nukuvuga. Igikoresho cyiza, kiramba kizicara kandi gifate. Rimwe na rimwe, hamwe n'ubwoko bushya, ushobora kubona urira gato hanyuma ugafunga nkuko igifuniko gihuye - mubisanzwe nibyiza. Ariko kumeneka bidasubirwaho bisobanura ikintu kibi: ibintu bitari byiza, umutwaro udahagije wa bolt, kwangirika kwangiritse, cyangwa flange guhura nibibazo. Ntushobora gukomeza gucana intege; ugomba gusuzuma.

None, Kuramba bisobanura iki?

Kurangiza, kuri a Imbaraga nyinshi z'umukara, kuramba bivuze ko ikomeza ibikorwa byayo byo gufunga ubuzima bwa serivisi bwateganijwe mubihe byagenwe. Igikara cyirabura nikigize ibyo, ariko kimwe gusa. Akazi kayo nukurinda mugihe cyo kubika no gutunganya, gutanga ubwumvikane buke, no gutanga bimwe byambere birwanya ruswa. Guterura biremereye bikorwa nimbaraga zibyuma bitanga umusaruro, kwihanganira kunyerera, no guhuza.

Mugihe cyo gusuzuma, ndabigabanya mubitekerezo: 1) Ibikoresho byingenzi kubidukikije bya shimi nubushyuhe. 2) Gushushanya (igikomere kiringaniye, kizunguruka, jacket) kubwoko bwumuvuduko nubwoko bwa flange. 3) Ubwoko bwo gutwikira bwo gukora hamwe na kashe ya mbere. 4) Uburyo bwo kwishyiriraho. Kubura umuntu uwo ari we wese abangamira sisitemu yose. Igicapo kiva mubukora kabuhariwe mukarere kegeranye cyane, nkakarere ka Yongnian aho Handan Zitai Yihuta ikora, akenshi ifite inyungu zumusaruro uhuriweho kuva wire / ububiko kugeza kubicuruzwa byarangiye, bishobora gusobanura guhuzagurika neza muribikoresho byingenzi - igice gikomeye.

Mukurangiza, ntugashishoze ukoresheje ibara. Kugaragaza ibisabwa mbere, hanyuma urebe uburyo bwo kuvura hejuru, niba bihari, bihuye. Igicapo kiramba cyane nicyo wibagiwe nyuma yo kwishyiriraho kuko ikora gusa, yaba umukara, ifeza, cyangwa ibyuma bisanzwe. Ibara niryo ryorohereza mububiko, ntabwo ari imashini. Imashini yita gusa kashe.
