Qhov sib txawv kub khiav lub rooj vag hom txiav txim siab lub qhov hluav taws xob qhov hluav taws xob thiab cov yam ntxwv ntawm cov hluav taws xob faib hluav taws xob, thiab ncaj qha txwv qhov chaw teeb tsa, lub kaum ntse ntse, hom thiab ntau npaum li cas ntawm cov thermocouples, uas yog lub hauv paus tseem ceeb rau kev ntsuas qhov taw qhia thaum ntxov.
Rau qhib sprue rooj vag nrog cov qauv yooj yim thiab cov ntaub ntawv du, cov cua sov faib yog sib xws thiab qhov ntsuas kub hloov pauv me me. Thermocouples tuaj yeem txais cov qauv ncaj nraim, teeb tsa hauv nruab nrab ntawm cov cua sov hauv nruab nrab ntawm cov nozzles, nrog cov txheej txheem kev teeb tsa qhov tob kom paub qhov ntsuas kub ruaj khov, thiab qhov teeb meem nyuaj yog tsawg nrog qhov xav tau tsawg dua.
Rau koob valve rooj vag dav siv nyob rau hauv siab- cov khoom muaj tseeb, lub zog sab hauv ntawm cov koob valve ua rau kev hloov pauv hauv zos, thiab qhov kub thiab txias nyob ze ntawm lub rooj vag hloov pom tseeb thaum qhib thiab kaw. Nws yog ib qho tsim nyog los npaj siab - rhiab heev bent thermocouples nyob ze rau pem hauv ntej kawg ntawm lub rooj vag los saib xyuas qhov kub thiab txias hloov ntawm cov yaj thaum lub sij hawm hloov, thiaj li kom tsis txhob muaj qhov tsis xws luag xws li xaim kos duab, cov khoom siv dripping thiab cov khoom siv lub rooj vag solidification.
Rau sab rooj vag thiab latent rooj vag kub runners txwv los ntawm pwm qauv, lub installation qhov chaw yog nqaim thiab thaiv. Cov thermocouples ncaj nraim tsis tuaj yeem ntsia tau rau hauv qhov chaw, yog li luv luv - hom kaum - kho tau cov thermocouples yuav tsum raug xaiv kom hla cov txheej txheem teeb meem thiab raug mus txog qhov ntsuas qhov ntsuas kub.
Tsis tas li ntawd, nyias nyias - zaj duab xis rooj vag kub runners muaj dav yaj tawm ntau thiab pom tseeb qhov kub ntawm qhov sib txawv, yog li nws yuav tsum tau nce tus naj npawb ntawm cov thermocouples rau thaj tsam ntsuas qhov ntsuas kub. Kev sib xyaw ua ke ntawm cov yam ntxwv ntawm cov rooj vag sib txawv los tsim cov phiaj xwm thermocouple layout schemes tuaj yeem ua rau qhov kub thiab txias tswj cov nyhuv thiab stabilize cov khoom molding zoo hauv paus.
