Lub hauv paus ntsiab lus tseem ceeb tom qab kuaj xyuas qhov kub khiav kev laus ntawm qhov kub thiab txias tsis xwm yeem yog nyob rau hauv kev txheeb xyuas qhov sib txawv ntawm qhov tseeb qhov kub thiab txias, ntsuas qhov kub sib txawv ntawm cov cheeb tsam, thiab soj ntsuam cov qauv hauv cov kev hloov pauv no. Thaum qhov kub sib txawv nyob rau hauv ib cheeb tsam tshwj xeeb tsis tu ncua tshaj ± 2℃, lossis thaum qhov kub ntawm lub taub hau poob ntau tshaj 5℃hauv qab nws qhov chaw teeb tsa -thiab qhov tsis sib xws no qhia tau tias muaj kev nthuav dav - nws tuaj yeem xaus lus tias lub kaw lus tau pib muaj hnub nyoog. Tus mob no feem ntau tshwm sim los ntawm cov cua kub degradation, thermocouple drift, los yog carbon buildup nyob rau hauv lub khiav raws; Yog li ntawd, yuav tsum muaj kev pov thawj zoo nrog rau kev tshuaj xyuas kho vajtse.
1. Temperature Field Mapping: Txheeb xyuas qhov chaw ntawm qhov tsis sib xws
Tom qab preheating pwm mus rau qhov kub thiab txias ua haujlwm thiab tuav nws li ob xuab moos, siv lub ntsuas kub sib cuag los ntsuas qhov ntsuas kub tiag tiag - los ntawm - taw tes rau ntawm qhov kawg ntawm txhua lub taub hau kub thiab hla ntawm lub phaj manifold.
Diagnostic Criteria:
Qhov kub thiab txias sib txawv hauv ib cheeb tsam > ± 2 degree: Qhia qhov cua sov tsis sib xws, uas tuaj yeem ua rau poob ntawm cov cua sov lub zog tso zis.
Nozzle tip kub < 5℃hauv qab no setpoint: Reflects tseem ceeb kub poob nyob rau hauv lub kawg ntawm tus khiav channel, feem ntau ntaus nqi rau carbon buildup los yog tsis txaus thermal rwb thaiv tsev.
Qhov sib txawv ntawm qhov kub thiab txias nce siab dua los yog sib npaug li 2℃tshaj peb qhov kev ntsuas sib law liag: Qhia tias cov txheej txheem kev laus tau nce zuj zus ntau dua li qhov tshwm sim los ntawm qhov sib txawv.
Kev Pom Zoo Kev Ua Haujlwm: Ua cov txheej txheem no txhua peb lub hlis los tsim "Tseem Ceeb Field Distribution Map," ua kom muaj txiaj ntsig zoo rau kev taug qab.
2. Kev sib piv nrog cov ntaub ntawv keeb kwm: Kev lees paub qhov kev poob qis
Sib piv qhov ntsuas kub tam sim no tiv thaiv cov khoom siv cov ntaub ntawv lees paub thawj zaug lossis cov txiaj ntsig hauv qab tau tsim los ntawm kev teeb tsa thawj zaug.
Cov ntsiab lus tseem ceeb:
Lub sijhawm cua sov teb rau ib cheeb tsam tshwj xeeb tau nce ntau dua 30%.
Lub setpoint kub yuav tsum tau manually nce (piv txwv li, los ntawm +10℃) kom tswj kom zoo pwm filling.
Tus tswj qhov kub thiab txias qhia txog qhov xwm txheej "ib txwm", tab sis qhov tseeb kub tseem qis dua qhov xav tau; Qhov no qhia tias muaj drift hauv lub teeb liab thermocouple.
Piv txwv Empirical: Hauv ib daim ntawv thov tshwj xeeb txuas pwm, nws tau tshawb pom tias qhov ntsuas kub ntawm Kub Nozzle #2 tsis tu ncua khiav 6℃qis dua qhov teeb tsa lub sijhawm txuas ntxiv. Qhov teeb meem no tau taug qab rov qab mus rau qhov qub thermocouple; Hloov cov khoom tivthaiv qhov kub thiab txias sib xws.
3. Kev koom ua ke nrog kev saib xyuas cov txheej txheem: Kev lees paub qhov cuam tshuam ntawm qhov ntsuas kub tsis xwm yeem
Siv lub tshuab txhaj tshuaj molding tshuab tswj kev sib tshuam-los yog kev soj ntsuam cov txheej txheem tshwj xeeb xws li Shotscope NX- los soj ntsuam thiab txheeb xyuas qhov ruaj khov ntawm pwm ntim lub sij hawm thiab lub siab nkhaus.
Associated Indicators:
Lub sijhawm ua haujlwm hloov pauv> ± 0.5 vib nas this;
Qhov hnyav sib txawv hauv ntau-cov khoom kab noj hniav nthuav dav ntawm ± 1% rau > ± 2.5%;
Lub zog hloov pauv nce zuj zus thaum lub sijhawm tuav, qhia txog qhov tsis sib xws ntawm cov dej ntws tawm.
Nco tseg: Cov kev tsis sib haum xeeb no feem ntau yog qhov cuam tshuam ncaj qha los ntawm qhov tsis sib xws ntawm qhov kub thiab txias.
4. Kev soj ntsuam dav dav: zam kev kuaj tsis raug
Qhov kub sib txawv ib leeg tsis tuaj yeem faib ncaj qha raws li "aging"; nws yuav tsum tau lees paub los ntawm tsawg kawg yog ib qho ntawm ob daim ntawv pov thawj hauv qab no:
|
Txhawb Nqa Pov Thawj |
Diagnostic tseem ceeb |
|
Kev sib txawv ntawm qhov kub thiab txias> ± 10% |
Paub meej tias hardware degradation; tswj cov teeb meem nrog kev tswj qhov kub thiab txias. |
|
Tsis zoo li thermocouple tsis kam lossis teeb liab drift |
Txoj cai tawm qhov ntsuas kub tsis raug; lees paub qhov tseeb qhov kub qhov sib txawv hauv qhov system. |
|
Qhov kub thiab txias sib txawv nqaim los ntawm<30% after carbon removal |
Qhia txog qhov muaj qhov tsis zoo ntawm cov qauv, tsis yog tsuas yog carbon buildup. |
Diagnostic Logic: Temperature Unevenness + Component Performance Exeeding Limits=Confirmed Laus; conversely, yog tias tsuas yog qhov ntsuas kub hloov pauv tau pom thaum cov khoom tseem nyob hauv cov lus qhia tshwj xeeb, qhov teeb meem yuav muaj kev cuam tshuam ib ntus.
