Izinto eziphakeme ze-temp gasket

Ngakho-ke,Ama-gaskets aphezulu aphezulu... Abantu bavame ukucabanga ukuthi konke kulula lapha - uthatha izinto ngephuzu eliphakeme elincibilikayo. Kepha lo mbono ongaqondile, uvame kakhulu, futhi ngagijimela kulokhu kaninginingi. Ukushisa okuphezulu nje kungenye yezici. Kubalulekile ukucubungula amanye amapharamitha amaningi: izakhiwo zemishini, ukumelana kwamakhemikhali, ukuhambisana nezinye izinto, kanye nezimo zokusebenza. Umuzwa uphakamisa ukuthi ukukhetha okulungile kwezinto ezibonakalayo kuyindlela ehlanganisiwe, hhayi nje ukusesha 'okushisayo' kakhulu.

Kungani kungapheli lokushisa okwanele ukuncibilika?

Konke kuqala ngokuqonda lokhoAma-gaskets aphezulu aphezuluAbasebenzanga ngokushisa okukhulu kakhulu, kodwa futhi nasebusweni lokushisa. Futhi leli banga lingahluka kakhulu. Izinto ezibonakalayo zingamelana ngokuphelele nemithwalo ye-Peak, kepha ngomsebenzi oqhubekayo ophansi kancane kunamazinga okushisa, ulahlekelwe yizakhiwo, ngokwesibonelo, ukuqina, futhi ekugcineni - ukuqina. Ngaphezu kwalokho, akuzona zonke izinto ezibekezelela ukubekezelela amazinga okushisa aphakeme azi ngokulinganayo ezimeni zemibandela yokushisa kwe-cyclic. Lokhu kuthinta kakhulu impilo yenkonzo.

Isibonelo, lapho sisebenza nezitofu eziphezulu, ekuqaleni sabheka i-graphite gasket. Iphuzu lokuncibilika legrafu, kunjalo, likhulu. Kepha i-graphite ngesivinini esikhulu futhi phambi kwe-oksijini iqala ukuwa, ukulahlekelwa ukunamathela kwayo kunobuso. Ukulahleka kokunamathela kuyindlela eqondile yokuvuza. Ngenxa yalokhu, senqabe ama-graphite futhi sashintshelwa ekusetshenzisweni okubiza kakhulu, kodwa ezinzile ekusebenzeni okusebenzayo, okuphezulu-kokuvelele kwe-fluororoplast.

Yiziphi izinto ezisetshenziswa kakhulu futhi kuliphi amacala?

Uma sikhuluma ngezinto ezijwayelekile, izikhundla eziholayo zihlala: izinto ze-ceramic (ikakhulukazi i-aricon carbide, ama-fluoroplasts (PTFE, PFA, ama-polymers asuselwa kuma-ceramics nama-polymers, kanye nezinye izinsimbi ezikhethekile kanye nama-alloys awo. Ukukhetha kuncike emisebenzini ethile.

Isibonelo, kumazinga okushisa aphezulu kakhulu (ngenhla kwe-1500 ° C), ama-gaskets we-ceramic cishe asetshenziswa njalo. Banokumelana okuhle kakhulu okushisayo kanye ne-inertia yamakhemikhali. Kepha ama-ceramics antekenteke, ngakho-ke kuvame ukuhlanganiswa nama-polymer matric ukukhulisa amandla okusebenza. Ezimweni lapho ukumelana kwamakhemikhali ezindaweni ezinolaka kubalulekile, kungcono ukusebenzisa ama-fluororoplasts. Basebenza kahle emazingeni okushisa anhlobonhlobo futhi abadalulwa amakhemikhali amaningi.

Isipiliyoni ngezinto ezihlanganisiwe: izinzuzo nokubi

Eminyakeni yakamuvaIzinto ezihlanganisiweInsimbi ithandwa kakhulu. Bakuvumela ukuthi uhlanganise izinzuzo zezinto zokwakha ezahlukahlukene - izinga lokushisa eliphakeme kanye nokumelana kwamakhemikhali kwama-ceramics ngokuguquguquka nokuqina kwemishini yama-polymers. Sisebenzise kwesinye sentuthuko yethu yamaphampu aphezulu avereture. Ngenxa yalokhu, bathola i-gasket ebekezelela amazinga okushisa aphezulu, ingcindezi kanye noketshezi olunolaka.

Kodwa-ke, izinto eziyinhlanganisela azincishwanga ezimbi. Ziyabiza kakhulu kunezinto zokwakha zendabuko, futhi inqubo yazo yokukhiqiza iyinkimbinkimbi ngokwengeziwe. Ngaphezu kwalokho, akulula ngaso sonke isikhathi ukubikezela ukuqina kwazo, ikakhulukazi ezimweni ezinzima zokusebenza. Uma i-matrix eyinhlanganisela ingalungile, ungathola i-gasket edonswa ngokushesha noma ichithwe.

Yini ebalulekile ukucubungula lapho ukhetha? Izakhiwo zemishini kanye nokuhambisana

Ngaphezu kokushisa nokumelana kwamakhemikhali, kubalulekile ukucubungula izakhiwo zemishini zezinto ezibonakalayo. I-gasket kufanele iqine ngokwanele ukumelana nengcindezi nemithwalo, kanye nezimo ngokwanele ukuqinisekisa ukulingana okuqinile ezindaweni ezikulo. Akumele sikhohlwe ngokuhambisana kwezinto ezinezinye izinto zohlelo. Ezinye izinto zokwakha zingasabela nezinye izinto, okubangela ukugqwala noma ezinye izici.

Isibonelo, lapho i-polymer ephezulu ye-polymer ixhumana nezinsimbi ezithile, kungenzeka ukuncipha kwe-dielectric, okuzolimaza i-gasket kanye nohlelo lonke. Ngakho-ke, kuyadingeka ukutadisha ngokucophelela ukuhambisana kwezinto zokwakha futhi, uma kunesidingo, sebenzisa izimbambo ezikhethekile noma ama-insulators.

Amaphutha okufanele agwenywe

Iphutha elivame kakhulu ukukhetha kwezinto ezibonakalayo kuphela ngephuzu lazo lokuncibilika, ngaphandle kokucabanga kwezinye izinto. Ngokuvamile bavame ukwenza iphutha, bakhethe izinto ezingabizi kakhulu, bangathathi ukuqina kwalo nokwethembeka. Elinye iphutha ukufakwa okungalungile kwe-gasket. Ukufakwa okungalungile kungaholela ekugqokeni kwayo ngaphambi kwesikhathi nokuvuza.

Emisebenzini yethu, bekukhona amacala lapho bekhetha izinto ezazisebenza kahle elabhorethri, kodwa ezimeni zangempela ezisebenzayo zacekelwa phansi ngokushesha. Isizathu sasivame ukufakwa okungafanele noma ukungahambelani kwezinto ezinezinto ezinezingxenye zohlelo. Ngakho-ke, ngaphambi kokukhetha lokho okuqukethwe, kuhlale kunconywa ukwenza ukuhlolwa ezimeni zangempela zokusebenza.

Iqiniso: Ama-gaskets amazinga okushisa aphezulu angumsebenzi obucayi

UkukhethaIzinto zokushisa -Resistant- Lokhu kungumsebenzi obhekele odinga ulwazi olujulile nesipiliyoni. Akunakwenzeka ukuncika kuphela kwimininingwane yethiyori - kuyadingeka ukubheka izimo zangempela zokusebenza nokuhlolwa. Le ukuphela kwendlela yokukhetha i-gasket ezokukhohlisa isikhathi eside.
