Anti-Carbon Deposition Performance Analysis: Thermocouple Temperature Constant Control Extends Copper Bushing Heater Service Life
Cov pa roj carbon deposition ntawm kub khiav cua sov Cheebtsam yog ib qho teeb meem tshwm sim uas plagues ntev -lub sij hawm nruam txhaj tshuaj molding ntau lawm. Tom qab lub hlis ntawm kev ua haujlwm tsis muaj kev cuam tshuam, cov txheej txheem cua sov zoo sib sau ua ke ntau ntawm cov yas volatile carbon deposits rau ntawm qhov chaw, uas ua rau txo cov thermal conduction efficiency, nce nyob rau hauv lub zos kub thiab ceev tivthaiv aging. Ntau pawg saib xyuas yuav tsum tau disassemble thiab ntxuav cov cua kub tsis tu ncua, uas cuam tshuam rau kev tsim khoom. Raws li kev siv tau zoo, tooj liab bushing kub khiav cov cua sov muaj kev tiv thaiv zoo heev - carbon deposition qauv zoo, thiab matched thermocouple qhov kub thiab txias tswj tshuab tuaj yeem txo cov pa roj carbon deposition tiam thiab zoo heev rau kev pab cuam lub voj voog ntawm cov khoom cua sov.
Lub hauv paus ua rau kub khiav cov pa roj carbon deposition yog ntev -lub sij hawm hauv zos overheating ntawm cov cua sov. Thaum lub cheeb tsam kub ntawm lub nozzle kub tshaj lub yas decomposition pib, volatile tshuaj precipitated los ntawm molten yas yuav undergo high -kub carbonization thiab ua raws li cov cua kub saum npoo, tsim ntom carbon deposit txheej. Lub caij nplooj ntoos hlav coil tso cua sov ib txwm muaj qhov chaw kub kub hauv zos, thiab qhov kub sib txawv ntawm qhov kub thiab qis - qhov kub thiab txias yog qhov loj. High - qhov kub thiab txias tsis tu ncua ua rau cov yas carbonization, ua rau cov pa roj carbon deposits sai thiab nyuaj rau ntxuav. Cov qauv cladding tseem ceeb ntawm tooj liab bushing heaters kiag li tshem tawm hauv zos siab - kub qhov chaw, thiab tag nrho cov khaubncaws sab nraud povtseg kub tsis txhob overheating carbonization tej yam kev mob.
Cov khoom siv tooj dag muaj qhov du thiab ruaj khov siab -kub oxidation tsis kam, uas tsis yooj yim rau kev cog lus nrog carbonized volatile tshuaj piv nrog cov hlau ntxhib ntawm cov qauv cua sov. Txawm hais tias ib qho me me ntawm cov volatiles adheres, nws yuav tsis tsim cov pa roj carbon monoxide ruaj khov, thiab kev tu pwm tuaj yeem yooj yim tshem tawm cov ntaub nplaum. Qhov tseem ceeb tshaj, cov thermocouple qhov ntsuas qhov ntsuas kub tsis tu ncua tuaj yeem kaw qhov kub khiav kub hauv qhov kev pom zoo ib ntus, kom tsis txhob kub dhau ntawm cov yas decomposition txwv. Feem ntau cov pa roj carbon deposition teeb meem nyob rau hauv tiag tiag ntau lawm yog tshwm sim los ntawm ntev -lub sij hawm me ntsis kub overshoot ntawm uncontrolled cua sov systems, uas yuav tsum tau zam tag nrho los ntawm qhov tseeb kub locking.
Thermocouple tiag tiag- lub sijhawm saib xyuas tuaj yeem ntes cov kev hloov pauv kub hloov pauv los ntawm cov pa roj carbon deposition ua ntej. Cov pa roj carbon monoxide me ntsis yuav txo qhov kub ntawm qhov hluav taws xob thiab ua rau qeeb kub nce ntawm cov cua sov bushing. Kev tswj qhov kub thiab txias tuaj yeem ua tau zoo- kho cua sov lub zog raws li cov ntaub ntawv tawm tswv yim kom tswj tau qhov kub thiab txias, zam kom tsis txhob muaj cov pa roj carbon ntau los ntawm qhov kub thiab txias thiab ua rau lub voj voog ntev ntev - lub sijhawm ua haujlwm ruaj khov.

Kev sib xyaw ua ke ntawm kev tiv thaiv- carbon deposition qauv thiab thermocouple qhov ntsuas kub tsis tu ncua ua rau tooj liab bushing heaters muaj qhov ua tau zoo ntev - lub sijhawm ua haujlwm zoo hauv kev txhaj tshuaj molding tsis tu ncua. Tsawg carbon deposition thiab tsis tshua muaj attenuation yam ntxwv txo cov khoom tu zaus thiab ntau lawm downtime poob. Kev ntsuas kub ntsuas ntsuas ntsuas thiab kev saib xyuas cov txheej txheem tuaj yeem tsim raws li lub voj voog ntau lawm thiab hom yas kom ua kom lub neej ua haujlwm zoo tshaj plaws thiab kev ua haujlwm ntau lawm.
