Dab tsi yog cov teeb meem kub khiav ntau tshaj plaws, thiab cov teeb meem thermocouple ua rau lub cev tsis ua haujlwm li cas? Kev kub khiav tsis raug ua rau cov nqi poob qis, qhov tsis zoo, cov khoom pov tseg, thiab pwm puas. Ntau qhov teeb meem tshwm sim los ntawm kev tswj qhov kub tsis ruaj khov, feem ntau txuas rau thermocouple malfunction, installation tsis raug, lossis teeb liab cuam tshuam. Kev nkag siab txog cov kev ua tsis tiav no pab cov molders siv kev tiv thaiv kev saib xyuas thiab txhim kho kev ruaj ntseg.
Kub drift los yog kev nyeem ntawv tsis ruaj khov yog ib qho teeb meem nquag, feem ntau tshwm sim los ntawm cov thermocouples degraded, puas cables, los yog av tsis zoo. Drifting kub ua rau tsis sib haum xeeb yaj viscosity, ua rau luv luv txhaj, flash, splay, los yog hlawv. Nyob rau tib lub sijhawm, thermal cycling rhuav tshem cov pob zeb hauv cov thermocouples, txo qhov raug.
Cov thermocouples tawg los yog disconnected ua rau poob ntawm qhov kub thiab txias tawm tswv yim. Cov tswj yuav nkag mus rau hom kev nyab xeeb, kaw cov cheeb tsam, lossis tso cai rau cua sov. Qhov no tuaj yeem hlawv cov khoom siv hluav taws xob, cov cua sov ua kom puas, lossis warp manifolds. Pwm kev co feem ntau ua rau cov kev sib txuas tsis muaj zog, tshwj xeeb tshaj yog ntawm cov ntsiab lus sib txuas.
Kev rwb thaiv tsev tsis zoo ua rau hluav taws xob to. Cov dej noo, resin paug, los yog lub cev puas tsuaj rau lub thermocouple sheath ua rau kev nyeem ntawv tsis raug, lub tswb tswj, thiab luv luv Circuit Court. Nyob rau hauv siab - ib puag ncig kub, rwb thaiv tsev deteriorates sai dua, accelerating tsis ua hauj lwm.
Thermocouple misplacement los yog kev teeb tsa tsis raug ua rau kev nyeem tsis raug. Sensors muab tso rau deb dhau ntawm qhov chaw yaj tsis tuaj yeem cuam tshuam cov txheej txheem tiag tiag. Overtightened installation yuav puas sensors thaum thermal expansion. Qhov tob lossis siab tsis raug kuj txo cov lus teb ceev.
Melt leakage thiab cov khoom degradation feem ntau cuam tshuam nrog kev tswj tsis zoo. Overheating ua rau polymer decomposition, dub specks, thiab carbon deposits. Underheating ua rau siab viscosity, siab siab, thiab tsis tiav filling. Ob leeg feem ntau tshwm sim los ntawm faulty thermocouple signals.
Cov teeb meem ntawm rooj vag xws li drooling, stringing, los yog khov qia los ntawm qhov tsis ruaj tsis khov nozzle ntsis kub. Thermocouples nyob deb dhau ntawm lub rooj vag tsis tuaj yeem hnov mob sai txaus kom muaj cua sov zoo.
Cov cua kub cua kub feem ntau yog tshwm sim los ntawm kev tswj tsis tau overheating vim qhov tsis ua hauj lwm ntawm thermocouple. Tsis muaj cov lus qhia meej, cov cua sov ua haujlwm ntawm lub zog tas li, ua rau muaj kev kub ntxhov sai.
Flow imbalance thiab inconsistent ib feem luj feem ntau qhia manifold kub variation, kuaj los ntawm underperforming thermocouples.
Txhawm rau txo cov teeb meem no, kev tshuaj xyuas tsis tu ncua ntawm thermocouples, cables, thiab connectors yog qhov tseem ceeb. Kev ntxuav, kev ntsuas kev tiv thaiv hluav taws xob, thiab kev txheeb xyuas qhov tseeb tiv thaiv kev ua tsis tiav feem ntau. Siv siab -zoo, hnav- tiv taus cov thermocouples tsim los rau cov neeg khiav dej num kub ua kom ntev kev pab cuam lub neej.
Hauv cov ntsiab lus, ntau qhov teeb meem kub khiav saum toj kawg nkaus yog ncaj qha lossis ncaj qha ntsig txog kev ua haujlwm ntawm thermocouple. Kev nqis peev hauv kev ntsuas qhov ntsuas kub kom ntseeg tau thiab kev saib xyuas niaj hnub ua tau zoo txhim kho kev ntseeg tau ntawm lub cev, txo cov nqi tsim khoom, thiab ua kom cov khoom zoo sib xws - qhov zoo.
