Packings: ezihlukahlukene futhi isicelo izici

Packings - kukhona imikhiqizo okukhomba amaseli indlala. Indaba ngentambo nokunwebeka elinendawo kwesigaba isikwele noma isiyingi. Umkhiqizo wenziwe asbestos ntambo nezinye izinto zokusetshenziswa. impahla Ngenxa unikezwa anganikeza yobunzima ezihambayo umile compounds izindlela. Izintambo bubekezelelwa kahle ithonya endaweni enobudlova futhi livikela okushisa. Ngokwe yokukhiqiza elinama umkhiqizo kungenziwa oluthathwa zibe asbestos futhi asbestos.

Packings kufanele uphawu kahle amayunithi kunoma iyiphi amayunithi zobunjiniyela. Abakwazi ihlukaniswe izinhlobo eziningi nezigaba. Ngamunye wabo has ezingeni elithile futhi sempilo. Ngokwesibonelo, imikhiqizo asbestos ingasetshenziswa imishini ukuthi icubungula uwoyela, futhi baxhumana amakhemikhali. inqubo ukuphrinta Advanced wenziwa esebenzisa ukucindezela ekhethekile.

Eminye imikhiqizo ungaqukatha amelwe isakhiwo graphite Imicu yotshani ukuthi ukuba afuthwe ngesibulali PTFE futhi wasisekela esebenzisa intambo ukotini. packings okunjalo zisetshenziselwa unamathelise plunger namaphampu centrifugal. Basuke ukuvimbela kahle amanzi ukuvuza. Futhi imikhiqizo okwamanje ezithunyelwe ukwazi ukulawula amaphampu ukushisa, kanye nokunciphisa amandla abo ukusetshenziswa. Iqiniso lokuthi babe ongaphakeme Coefficient friction. Inzuzo graphite izihloko siwukuthi bangamalungu ukumelana kakhulu lokushisa eliphezulu (degrees mayelana 550 ), Chemical kuhlasela. Nokho, akunakwenzeka, amandla okubeka kwento nomswakama ngoba kungaba nomthelela ukugqwala metal ku izindlela.

Graphite packings sizibangela nivame. Sebenzisa mikhiqizo kufanele kube bonyana batshidze izindawo lizoshona zonke izindlela zokuthutha. inqubo ukuphrinta ngokuvamile kudingeka Izinsiza ngesikhathi zokugwema ukuphuka amapayipi amanzi noma bafudumale izinhlelo. Ngenxa relievers okungagcini nje ukumisa ukuvuza, kodwa futhi ukuvimbela ivela khona phambili.

Uma usebenzisa ibhokisi ukugxusha ukupakisha for amaphampu centrifugal, kungcono ukuba ukhethe intambo ukotini. Oku-umkhiqizo kufanele ofakwe uwoyela isilinda, lapho kuzoba khona esincane wax. Buhle le nto ukuthi kungenza umelane nezingcindezi kuze 20 MPA futhi yenza imisebenzi yayo angaphezu ububanzi lokushisa ububanzi (kusuka degrees -40 kuya +100). Nokho, imikhiqizo ngokushesha wabhubhisa bedle alkalis futhi acid.

I samuntu ezithakazelisayo lwezimpawu polymer indlala, okuyinto zenziwa esekelwe fluoropolymer. Abakwazi kwenziwe ngesimo izindandatho, izigqebhezi zokudlala noma cuffs. Le nto has a kuyaqina ongaphakeme, ngakho ngaphezu zisebenzisa lwezimpawu zenjoloba. Futhi inqobo ukwahlukahlukana packings, kukhona labo lapho esetshenziswa wire ithusi.
