Packings: ezahlukeneyo kunye nesicelo neempawu

Packings - zimveliso ukuba kuthagetha iiseli ndlala. Le nto ingumsipha elastic ene icandelo isikwere okanye setyhula. Imveliso yenziwa asbestos vulu kunye nezinye izinto. izinto obekiweyo uyakwazi ukunika yengxinano ezihambayo kunye nemixube iindlela zokubhala. Ziqhawukile ukunyamezeleka kakuhle kwempembelelo bume ndlongondlongo kunye ukumelana neenguqu obushushu. Ngokutsho ukuvelisa i impahla ethengiswayo zihlelwe ibe asbestos ne-asbestos.

Packings kufuneka utywinwe kakuhle liyunithi nayiphi units zobunjineli. Zingakotshwa zohlulwa ngokwendidi ezininzi neeklasi. Ngamnye kubo kwinqanaba elithile kunye nexesha. Umzekelo, iimveliso asbestos zingasetyenziswa isixhobo oqhubekekisa ioli, kwaye anxibelelana ngayo iikhemikhali. inkqubo ushicilelo Advanced lwenziwa ngendlela bokushicilela ezizodwa.

Ezinye mveliso ezinamaphepha zimelwe isakhiwo kwimicu grafayithi ukuba buzane PTFE kwaye luqiniswe ngokusebenzisa ngomsonto cotton. packings ezinjalo lisetyenziselwa ukuvala ibhola kunye iimpompo centrifugal. Bona ukunqanda kakuhle ukuvuza kwamanzi. Kunye neemveliso kodwa ezithunyelwe uyakwazi ukulawula iimpompo ubushushu, kwakunye ukwehlisa intsebenziso yabo yombane. Inyaniso kukuba eliphantsi ukungavumelani kwe kunobunye. Inzuzo amanqaku grafayithi kukuba ukumelana kakhulu lobushushu eliphezulu (malunga 550 degrees ), Chemical ukuhlasela. Nangona kunjalo, akunakwenzeka ukuba avavanye imathiriyeli ukufuma kuba umntu negalelo umhlwa ngentsimbi kule seli.

packings grafayithi uziqeshile-lubricated. Sebenzisa le mveliso kufuneka ukuba kutywinwe iindawo uya kuhla zonke iindlela zokuthutha. inkqubo ushicilelo afuneka eziluncedo ngexesha breakage kwemibhobho yamanzi okanye iinkqubo ukufudumeza. Ngenxa okuphelisa kunokwenzeka kuphela ukuba ukunqanda ukuvuza, kodwa ukuthintela ukwenzeka yayo engaphezulu.

Ukuba usebenzisa ibhokisi Akunakuba ukupakisha kwimibhobho yeempompo centrifugal, kungcono ukukhetha intambo cotton. Pre-mveliso kufuneka kufuma kumatanki oyile, apho kuya kubakho imali encinci ngumthwebeba. Abaxhamla kule nto kukuba ukumelana ingcinezelo ukuya ku-20 MPA kwaye yenza imisebenzi yayo kakuhle ngaphezu ebanzi uluhlu lobushushu (ukusuka iqondo -40 ukuya +100). Kodwa ke, iimveliso zitshabalale ngokukhawuleza phantsi kwempembelelo alkalis kunye asidi.

An ngobuwena umdla kukho amatywina Polymer ndlala ezenziwe ngokusekelwe fluoropolymer. Ukuba zingenziwa ngohlobo amakhonkco, iitshiphusi okanye cuffs. Le nto uba luthambe ephantsi, ngoko ukongeza ukusebenzisa irabha ezitywine. Kwakhona yanika ukwahlukahlukana packings, kukho abo apho kusetyenziswa ucingo lobhedu.
