Xaiv cov qauv ntawm Thermocouple tiv thaiv lub tes tsho rau kev ua haujlwm hnyav

Kev cia siab ib leeg rau ntawm lub plhaub qub ntawm cov thermocouples tuaj yeem tsis tuaj yeem tiv thaiv kev puas tsuaj sab nraud rau lub sijhawm ntev hauv qhov chaw txhaj tshuaj molding ntau lawm nrog rau kev ua haujlwm hnyav xws li kub kub, muaj zog corrosion, cov khoom hnyav scouring, thiab plua plav ntom ntom. Nws tseem yog ib qho yooj yim ua rau kev sojntsuam hnav, lub plhaub corrosion, thiab ua tsis tiav thaum ntxov hauv lub sijhawm luv luv. Kev siv tshwj xeeb siab- lub tes tsho tiv thaiv kev ua tau zoo rau cov thermocouples tau ua pov thawj los ua qhov kev tiv thaiv kev tiv thaiv zoo uas tuaj yeem ua kom ruaj khov ntev -lub sijhawm ntsuas qhov kub thiab txias, ua kom lub neej ntev ntawm qhov ntsuas kub ntsuas, thiab cais ntau yam kev cuam tshuam sab nraud. Txhawm rau kom phim cov khoom tiv thaiv zoo tshaj plaws raws li ntau yam xwm txheej ua haujlwm, nws yuav tsum ua kom pom tseeb cov qauv kev xaiv ntawm lub tes tsho tiv thaiv.

High-kub engineering plastics thiab tshwj xeeb hloov plastics yog cov piv txwv ntawm ultrahigh kub molding ib puag ncig uas yog lub hom phiaj tseem ceeb ntawm siab -cov tsho tiv thaiv kub. Lub plhaub hlau zoo ib yam muaj qhov tsis zoo rau siab - kub oxidation, cov khoom muag muag, thiab cov qauv deformation nyob rau hauv xws li kev ua haujlwm ib puag ncig, uas kuj muaj qhov ntev -lub sij hawm tsis tu ncua siab - kub tawg thiab kub conduction. Imported high-kub alloy cov ntaub ntawv, xws li molybdenum alloy thiab chromium-nickel alloy, yog siv los ua tus hwm siab - kub tiv thaiv tes tsho. Cov ntaub ntawv no tuaj yeem tiv taus qhov kub thiab txias tsis tu ncua tsis hloov lawv tus kheej cov qauv hlau. Lawv tuaj yeem tswj xyuas cov phab ntsa sab nraud kom zoo rau kev ua haujlwm ruaj khov ntawm cov cua sov ua haujlwm, muaj kev tiv thaiv zoo rau oxidation ntawm qhov kub thiab txias, thiab yuav tsis tawm cov oxide tuab rau ntawm qhov chaw ntev heev. Thaum xaiv, xyuam xim rau lub tes tsho qhov ntsuas qhov ntsuas kub tsis tu ncua thiab xaiv qhov ntsuas kub kom haum raws li tus neeg khiav dej num kub qhov kub ua haujlwm siab tshaj plaws. Tsis txhob siv lub tes tsho qis- qhov kub thiab txias thaum lub sij hawm kub los tiv thaiv cov qauv kev tiv thaiv tsis tau sai.

Cov iav fiber ntau- puv polymers, cov ntaub ntawv ntxiv nrog cov ntxhia hmoov, thiab lwm yam siab - cov ntaub ntawv hardness yog tsim tshwj xeeb los ntawm kev siv coj- tiv thaiv kev cuam tshuam - tiv thaiv lub tes tsho. Lub plhaub zoo tib yam yuav raug polished sai sai thiab puas thaum lub sij hawm siab - txheej txheem melt flow vim hais tias cov ntaub ntawv nyuaj lossi tawm tsam thiab scour lub thermocouple sojntsuam nto. Hnav- cov tsho tiv thaiv tiv thaiv nrog cov tawv tawv heev thiab muaj zog tiv thaiv -scouring muaj peev xwm siv cov phab ntsa tuab tuab thiab cov thev naus laus zis kho qhov tawv tawv. Txhawm rau tiv thaiv kev sib txhuam ncaj qha thiab hnav ntawm cov khoom tawv tawv thiab lub plhaub qub, cov phab ntsa sab hauv snugly haum rau lub thermocouple sojntsuam, dispersing lub instantaneous cuam tshuam quab yuam uas tsim los ntawm cov khoom ntws. Integrated seamless forming tes tsho yuav tsum yog qhov tseem ceeb thoob plaws hauv txoj kev xaiv vim tias lawv muaj peev xwm ua haujlwm ntev dua - lub sij hawm hloov kev cuam tshuam thiab muaj kev cuam tshuam tag nrho ntau dua li cov qauv sib txuas.

Los tiv thaiv- lub tes tsho tiv thaiv corrosion tuaj yeem siv rau hauv cov chaw tsim khoom uas muaj ntau cov pa roj acidic volatile, oily corrosive chav, thiab cov tshuaj precipitates -xws li nplaim hluav taws- cov yas retardant, degradable plastics, thiab cov khoom siv raw khoom hloov kho cov ntaub ntawv-. Cov ntaub ntawv corrosive no yuav maj mam erode lub thermocouples 'hlau plhaub, nkag mus rau hauv sab hauv los ntawm microscopic qhov, thiab corrode lub insulating fillers thiab internal hlau cores. Multi-txheej txheej tiv thaiv-corrosion passivation txheej yog siv rau saum npoo ntawm tag nrho cov khoom tiv thaiv- lub tes tsho tiv thaiv corrosion, uas siv cov khoom siv vuam thiab sealing tshuab thiab tsis muaj qhov khoob thoob plaws. Cov txheej no zoo cais tawm qhov ntxeem tau ntawm cov corrosive gasses thiab kua precipitates. Txhawm rau ua tiav qhov xav tau los tiv thaiv{11}} tiv thaiv corrosion, nws yog ib qho tsim nyog los txheeb xyuas hom kev tiv thaiv corrosion ntawm lub tes tsho, xaiv cov kua qaub- cov qauv tiv thaiv rau acidic gas ib puag ncig, thiab xaiv cov roj- tiv taus thiab hnyav- cov lus qhia tshwj xeeb rau roj fume{15}} nplua nuj ib puag ncig.

Kev sib koom ua ke tshwj xeeb yuav tsum tau ua raws li ntxiv rau kev xaiv kev faib ua haujlwm. Ua ntej, txhawm rau kom tswj tau qhov kub ntawm qhov ceev thiab qhov ntsuas kub ntawm qhov ntsuas kub, lub sab hauv txoj kab uas hla ntawm lub tes tsho tiv thaiv yuav tsum sib phim rau sab nraud ntawm qhov sib txuas ntawm cov thermocouple sojntsuam. Qhov no yuav muab lub rooj sib dhos snug haum yam tsis muaj qhov sib txawv ntau dhau los yog yuam extrusion. Qhov thib ob, lub tes tsho tiv thaiv qhov ntev yuav tsum tau muab tso rau kom tsim nyog raws li qhov tseeb ntawm qhov tob tob kom nws tuaj yeem npog tag nrho cov thawj qhov ntsuas kub ntsuas qhov ntsuas qhov ntsuas thaj tsam yam tsis cuam tshuam nrog cov xov txuas tsis tu ncua thiab kho. Thib peb, txhawm rau ua kom haum rau ntau yam kev xav tau, cov qauv tsim yuav tsum raug xaiv raws li qhov chaw teeb tsa, nrog lub tes tsho ncaj ncaj rau qhov chaw qhib thiab tshwj xeeb tsim khoov lub tes tsho tiv thaiv rau qhov chaw nqaim nqaim.

Tshawb xyuas lub tes tsho tiv thaiv qhov hnav, corrosion, thiab deformation tsis tu ncua thaum siv txhua hnub thiab tu. Hloov cov tsho uas hnav tsis zoo los yog ua haujlwm tsis zoo ntawm lub tes tsho tiv thaiv kom sai li sai tau. Nws yuav tsum tau hais tias lub tes tsho tiv thaiv tsuas yog muab kev tiv thaiv sab nraud thiab tsis muaj kev cuam tshuam rau lub thermocouple lub peev xwm los nkag siab qhov kub thiab txias. Txawm tias muaj cov khoom siv tiv thaiv, lub cev thermocouple tseem yuav tsum tau ntxuav kom zoo thiab ntsuas qhov tsis tu ncua. Ib qho kev tiv thaiv sab nraud muaj zog rau cov ntsuas kub ntsuas cov khoom tuaj yeem tsim los ntawm kev tshawb fawb xaiv thiab siv lub tes tsho tiv thaiv thermocouple ua raws li cov qauv kev ua haujlwm. Qhov no tseem tuaj yeem txo qis qhov tsis ua hauj lwm ntawm cov khoom siv hauv qhov chaw hnyav, txo qhov zaus ntawm kev hloov pauv, thiab tsim kom muaj kev ua haujlwm ruaj khov dua rau kev tsim cov khoom tshwj xeeb txhaj tshuaj molding.
