Tshaj - ntim thiab hauv qab - ntim yog cov teeb meem tshwm sim los ntawm qhov tsis sib xws ntawm cov viscosity, uas yog tswj ncaj qha los ntawm qhov kub thiab txias. Yog tias cov yaj kub dhau lawm, nws ntws yooj yim dhau, ua rau dhau - ntim, nyem, thiab ncua sij hawm mus. Yog tias cov yaj txias dhau lawm, viscosity nce, ua rau hauv qab - ntim, txhaj tshuaj luv luv, thiab cov cim dab dej. Thermocouples tswj qhov kub thiab txias kom ruaj khov ua kom tus cwj pwm tuaj yeem kwv yees, tiv thaiv cov teeb meem no.
Hauv ntau-kab kab noj hniav pwm, qhov kub sib txawv ntawm cov nozzles ua rau tsis sib xws. Ib kab noj hniav tuaj yeem dhau - ntim thaum lwm qhov qis dua - ntim, ua rau cov khoom seem siab. Txhua lub thermocouple saib xyuas nws thaj tsam ntawm nws tus kheej, tso cai rau tus tswj kom sib npaug ntawm cov cua sov thiab ua kom cov viscosity zoo ib yam thoob plaws txhua qhov kab noj hniav. Qhov kev sib npaug no tshwj xeeb yog qhov tseem ceeb rau siab -cavitation pwm ua qhov me me, qhov tseeb.
Thaum lub sij hawm tuav, kub stability ncaj qha cuam tshuam rau packing siab kis tau tus mob. Lub teeb liab thermocouple ruaj khov ua kom ntseeg tau tias cov yaj nyob ib puag ncig, tso cai rau kev ntim khoom kom zoo yam tsis muaj siab dhau. Kev hloov pauv kub cuam tshuam cov txheej txheem no, ua rau cov neeg ua haujlwm tsis tuaj yeem ua tiav cov txiaj ntsig zoo ib yam. Los ntawm kev tswj xyuas qhov kub thiab txias, cov thermocouples txhim kho qhov hnyav sib xws, txo qis flash thiab txhaj tshuaj luv luv, thiab ua kom tag nrho cov txheej txheem ruaj khov.
