A plate heat exchangerchishandiso chinoshanda zvakanyanya uye chakabatana kupisa kupisa chinoshandiswa zvakanyanya mukupisa, kutonhora, kubuda evaporation, condensation, uye mamwe maitiro. Iyo ine mutsara wesimbi mahwendefa akavharwa nerubber gaskets, achigadzira nhevedzano yekuyerera nzira. Fluids inoyerera pakati pemahwendefa ari pedyo, kuchinjana kupisa kuburikidza nemahwendefa e conductive.

Nekudaro, mumashandisirwo anoshanda, magasi erabha ari muplate heat exchangers anogona kukuvara, zvichikonzera kudzikiswa kwekutsinhana kwekushisa uye zvinogona kukanganisa kushanda kwakajairwa kwehurongwa hwese. Saka, ndezvipi zvikonzero zvekukuvadza kwerubha gasket muplate heat exchangers?

Kemikari Corrosion

Chekutanga, kemikari corrosion ndiyo inowanzokonzera kukanganisa kwerubha gasket. Mamiriro emakemikari emvura mukati memuchinjiziri wekupisa, senge maasidhi akasimba, mabhesi akasimba, kana organic solvents, anogona kuita nerubber gasket material, zvichiita kuti iderere, ipfave, kana kuoma, zvichiita kuti ikuvare. Pamusoro pezvo, mamwe makemikari anogona kukurumidzira kuchembera kwezvinhu zverabha, zvichiita kuti magasi arasikirwe nekusimba uye kuwedzera kuwedzera kwekukuvara.

High Temperature

Chechipiri, tembiricha yakakwira zvakare chikonzero chakakosha chekukuvara kwerubha gasket. Imwe neimwe mhando yerubha zvinhu ine yayo yekushivirira kwekushisa. Kana tembiricha iri mukati memuchinjiziri wekupisa yakadarika rubber gasket yekushivirira, gasket inogona kupfava, kuchembera, kurasikirwa nekusimba, uye pakupedzisira kukuvara. Kunyanya, munzvimbo dzepamusoro-tembiricha, kushanda kwezvinhu zverubha kunoderera zvakanyanya, zvichiwedzera njodzi yekukuvara.

Kunyanya Kudzvinyirira

Kuwedzeredza kudzvanywa chimwe chikonzero chekukuvara kwerubha gasket. Munguva yekushanda kweanopisa kupisa, masisitimu anodzvanya shanduko kana zvikanganiso zvekushanda zvinogona kukonzera kuti rubber gasket itakure kudzvanywa kupfuura kushivirira kwayo, zvichikonzera kukuvara. Kunyanya muzviitiko zvenguva zhinji system inotanga nekumira kana kudzvanyirira kwakanyanya, iyo gasket inonyanya kukuvara.

Fluid Impact

Fluid kukanganisa kunogonawo kukonzera rubber gasket kukuvara. Kana zvinwiwa zvichiyerera nekumhanya kwakanyanya, simba rekuita pa gasket rakakura, uye kuratidzwa kwenguva refu kumasimba akadaro kunogona kukonzera kukuvara kwegasket. Izvi zvinonyanya kuomarara painopinza kana painobuda neinopisa, uko kumhanya kwemvura kwakakwira.

Kuiswa kusina kunaka

Kuisa zvisina kunaka chinhu chemunhu chinokonzera rubber gasket kukuvara. Panguva yekuisa, kana gasket isina kunyatsoiswa kana kumanikidzwa zvakanyanya, inogona kukuvara. Pamusoro pezvo, zvishandiso zvisina kufanira kana nzira dzinoshandiswa panguva yekubvisa uye kuiswa nevashandi zvinogona kukuvadza gasket.

Natural Kuchembera

Nekufamba kwenguva, zvinhu zverabha zvinochembera nekuda kweoxidation, zvichirasikirwa nekuisa chisimbiso. Uku kuchembera kunokwidziridzwa mukupisa kwepamusoro-soro, hunyoro hwepamusoro, kana nharaunda dzakasimba dzeUV, kupfupisa hupenyu hwegasket.

Operational Errors

Kukanganisa kwekushanda kunogona kukonzera kukanganisa kwerubha gasket. Semuyenzaniso, kukurumidza kuvhura kana kuvhara mavharuvhu panguva yekupisa exchanger oparesheni kunogona kukonzera kusimba kuchinjika, kukuvadza gasket. Uyezve, kusatevedzera maitiro ekushanda kunogona kukonzera kukuvara kwegasket.

Maintenance Yakashata

Kusagadzirisa zvakanaka chimwe chikonzero chekukuvara kwerubha gasket. Pasina kucheneswa kwakakodzera uye kuongororwa panguva yekushanda kwenguva refu, tsvina uye zvimedu zvinogona kukonzera kupfeka kana kukwenya pane gasket. Izvi zvinonyanya kunetsa mumamiriro asina kunaka emvura kana zvinwiwa zvine akawanda akasimba masisitimu, zvichiita kuti gasket risanyanya kukuvara.

Kuve nechokwadi chekushanda kwakajairika kweplate heat exchanger uye kuwedzera hupenyu hwerubha gasket, matanho akati wandei anofanirwa kutorwa. Chekutanga, panguva yekugadzira uye yekusarudza chikamu, zvakakosha kuti unzwisise mamiriro ekushanda uye fluid zvimiro zveanopisa kupisa zvizere uye sarudza yakakodzera gasket zvinhu uye zvine musoro nzira dzekushandisa. Chechipiri, panguva yekuisa uye kushanda, kunyatsotevedzera maitiro ekushanda kunodiwa kuti udzivise kukanganisa kunokonzerwa nezvikanganiso zvekushanda. Uyezve, kuongorora nguva dzose, kucheneswa, uye kugadzirisa muchina wekupisa, pamwe chete nekutsiviwa nenguva kwemagasi akakuvadzwa, zvakakosha.

Mukupedzisa, zvikonzero zvekukuvadza kwerubha gasket mukatindiro inopisa exchangerszvakasiyana-siyana, kusanganisira kemikari corrosion, tembiricha yakakwira, kudzvanyirira kwakanyanya, kukanganiswa kwemvura, kuiswa kwakashata, kuchembera kwezvinhu, zvikanganiso zvekushanda, uye kusagadzirisa zvakanaka. Kuve nechokwadi chekushanda kwakajairika kweanopisa kupisa uye kuwedzera hupenyu hwegasket, akawanda ekudzivirira uye ekugadzirisa matanho anofanirwa kutorwa. Kuburikidza nedhizaini inonzwisisika, kusarudzwa, kuisirwa, kushanda, uye kugadzirisa, njodzi yekukuvara kwegasket inogona kuderedzwa, kuvandudza kushanda kweanopisa kupisa uye kugadzikana.
