Lub tshuab nqus tsev khov- ziab kom qhuav yog nyob ntawm lub tshuab nqus tsev siab kom paub txog qhov ncaj qha sublimation ntawm cov dej khov hauv cov ntaub ntawv. Thaum cov cuab yeej muaj cov ntsiab lus ntawm cov pa tawm, cov cua sab nraud txuas ntxiv nkag mus rau hauv lub tshuab ziab khaub ncaws. Lub tshuab nqus tsev yuav tsum tau ua kom khiav ntawm siab load kom tswj tau lub hom phiaj nqus tus nqi. Lub tshuab nqus tsev tsis txaus yuav ua rau tus nqi sublimation qeeb. Cov ntaub ntawv muaj feem xyuam rau lub zos melting, shrinkage thiab lub cev qhuav dej, ua rau cov khoom tiav tsis tsim nyog kev ntxhib los mos thiab zoo heev tsis kam lees tus nqi. Hauv qhov xwm txheej hnyav, tag nrho cov khoom siv raw yuav raug pov tseg.
Feem ntau lub tshuab nqus tsev vacuum tsis ua haujlwm yog los ntawm qhov system sealing. Cov khoom tseem ceeb muaj xws li drying chamber door silicone sealing strip, pipeline flange sealing gaskets, nqus valve sealing rings, dynamic ncej seals ntawm turnover mechanisms. Cov khoom siv roj hmab polymer no ua haujlwm sib hloov hauv qhov kub thiab txias, qhov kub thiab txias hloov ib puag ncig rau lub sijhawm ntev. Tom qab ua haujlwm ntev -, cov teeb meem xws li hardening, cracking, deformation, nto adhesion ntawm cov khoom seem yuav maj mam tshwm. Cov qhov khoob me me uas tsim los ntawm cov teeb meem no dhau los ua txoj hauv kev rau huab cua nkag.
Cov tuam txhab lag luam yuav tsum tsim cov kev tshuaj xyuas tsis tu ncua rau cov khoom sib khi. Ua ntej txhua pawg tsim khoom, cov neeg ua haujlwm yuav tsum tau kuaj xyuas seb lub qhov rooj kaw qhov rooj puas zoo, ntxuav cov khib nyiab, roj thiab lwm yam khoom seem uas txuas rau saum npoo. Cov teeb meem txawv teb chaws daig ntawm lub sealing nto thiab cov roj hmab sawb yuav ua rau tsis tiav compression thiab mus tas li indentation ntawm sealing sawb. Yog tias pom muaj zog, tawg thiab elastic poob, hloov cov khoom siv hauv lub sijhawm es tsis txhob txuas ntxiv ntau lawm.
Rau cov cuab yeej uas pom tseeb lub tshuab nqus tsev vacuum, cov txheej txheem kom pom cov pa taws yuav tsum tau ua. Cov txheej txheem kev kuaj pom muaj xws li kev ntsuas lub tshuab nqus tsev zoo li qub, tshuaj ntsuam xyuas lub tshuab nqus dej. Tom qab lub khov- lub tshuab ziab khaub ncaws raug kaw thiab tso rau hauv lub tshuab nqus tsev, txiav tawm lub tshuab nqus tsev thiab kaw lub tshuab nqus tsev nrawm. Yog hais tias lub siab nce siab tshaj tus qauv ntau, nws ua pov thawj tias muaj qhov pom tseeb to. Tom qab ntawd tsom mus rau kev kuaj xyuas lub qhov rooj, txhua qhov kev sib txuas flange, qhov chaw valve. Nws yog ib qho tsim nyog yuav tsum nco ntsoov tias kev quab yuam ntau dhau thaum kaw lub qhov rooj yuav ua rau lub cev deformation mus tas li ntawm lub sealing sawb; tsim nyog clamping quab yuam yuav tsum tau khaws cia raws li cov khoom yuav tsum tau.
Ntau lub chaw tsim khoom tsuas yog hloov cov khoom siv tom qab muaj qhov tshwm sim loj heev, uas ua rau muaj kev pheej hmoo ntawm kev hloov pauv hauv kev tsim khoom. Kev saib xyuas txhua hnub tuaj yeem ua rau lub neej ua haujlwm ntev ntawm cov khoom sib khi. Tsis txhob siv cov tshuaj ntxuav corrosive los txhuam cov roj hmab; tiv thaiv ntev - lub sij hawm ncaj qha mus cuag cov roj thiab kua qaub kua txiv. Rau lub sijhawm ntev - cov khoom kaw lub sijhawm, ua kom lub qhov rooj qhib me ntsis kom tsis txhob ntev - lub sij hawm compression deformation ntawm sealing strip.
Kev tswj xyuas kev sib khi zoo tuaj yeem tswj xyuas lub tshuab nqus tsev ruaj khov ntawm lub tshuab ziab khaub ncaws, lav qhov kev ua kom qhuav zoo ib yam ntawm txhua pawg ntawm cov khoom siv, tswj lub zog siv nyob rau hauv qhov kev xav tau, thiab txo qis cov khoom lag luam tsis tsim nyog rau khov - cov khoom lag luam ua zaub mov qhuav.
