Dab tsi ua haujlwm tsis zoo tshwm sim hauv kev siv kub khiav txhua hnub?

Ntau yam khoom siv tsis raug tuaj yeem tshwm sim tau yooj yim nyob rau hauv ntev - lub sij hawm tas mus li kev tsim khoom thiab siv cov txheej txheem kub khiav, uas yog cuam tshuam los ntawm cov yam ntxwv xws li cov khoom siv raw, pwm ua haujlwm ib puag ncig, kev ua haujlwm tshwj xeeb, kev laus laus, thiab kev teeb tsa yuam kev. Feem ntau ntawm cov kev ua txhaum no yog ze ze rau qhov tsis ua hauj lwm, kev tshawb nrhiav tsis raug, kev sib cuag tsis zoo, thiab cov teeb liab txawv txav ntawm cov tub ntxhais kub ntsuas cov khoom siv uas sawv cev los ntawm cov kub khiav thermocouples. Kev nkag siab txog qhov kub khiav tsis zoo, qhov ua txhaum ntawm qhov tshwm sim, thiab cov hauv paus ntsiab lus tuaj yeem pab cov neeg ua haujlwm tu cov neeg ua haujlwm kom paub txog cov teeb meem tam sim ntawd, tshem tawm cov teeb meem tam sim ntawd, txiav lub sijhawm kaw lub sijhawm, thiab tiv thaiv kev tsim khoom ntawm cov khoom yas faulty.

Qhov teeb meem feem ntau nrog cov neeg khiav dej num kub hauv kev siv txhua hnub yog qhov kub thiab txias tsis zoo hloov pauv, uas suav nrog qhov tsis muaj peev xwm ncav cuag qhov xav tau cua sov kub, cua sov qeeb qeeb, kub kub kub dhia, qhov kub tsis ruaj khov ntab nce thiab nqis, thiab qhov kub tsis sib haum ntawm txhua qhov kev faib tawm. Cov teeb meem ntawm cov thermocouple tsis ua hauj lwm yog thawj qhov ua rau cov teeb meem no: xoob thermocouple kev teeb tsa ua rau muaj kev sib cuag tsis zoo nrog cov khoom siv cua sov, uas ua rau qeeb qhov ntsuas kub thiab ntsuas kub tsawg; ntev - lub sij hawm siab - kub siv ua rau cov laus hlau core thiab teeb liab kis distortion ntawm thermocouples, uas ua rau ib tug cia li dhia nyob rau hauv cov zaub kub; Thermocouple siab-kub oxidation thiab sab hauv Circuit Court breakage ua rau tsis muaj qhov ntsuas kub tawm tswv yim, thiab tus tswj qhov kub thiab txias qhia txog tus lej tsis zoo. Qhov kub tsis sib xws kuj tuaj yeem tshwm sim los ntawm cov cua kub yeeb nkab burnout, xaim hlua hluav taws xob sib txuas, thiab cov rwb thaiv tsev kub tsis txaus, txawm li cas los xij feem ntau ntawm cov teeb meem kub hloov pauv feem ntau yog tshwm sim los ntawm thermocouple tsis ua haujlwm.

Kev sib dhos sib txawv ntawm lub manifold thiab nozzle nrog rau qhov chaw ntawm qhov kub khiav qhov kev sib txuas rau pwm kab noj hniav yog qhov chaw rau cov kub khiav sab hauv cov khoom ua txhaum. Melt overflow ntawm qhov sib txawv, cov khoom adhering rau qhov kub khiav nto, thiab nyuaj pwm qhib tom qab txias yog thawj cov tsos mob. Cov laj thawj tseem ceeb yog kev teeb tsa lub zog ntau dhau, kev laus thiab corrosion ntawm siab - kub resistant sealing gaskets, kev txhaj tshuaj ntau dhau, thiab qhov tsis txaus siab thermal expansion reserved qhov sib txawv hauv qhov kub khiav cov qauv tsim. Nyob rau lub sijhawm no, cov cua sov hauv zos ntau dhau thiab ua rau cov khoom siv sib khi ua kom nrawm yog tshwm sim los ntawm qhov ntev - lub sij hawm kub sib txawv ntsuas los ntawm cov thermocouples imprecise, uas ua rau indirect ua rau muaj teeb meem ntawm cov khoom to.

Kub khiav kub tsis ua hauj lwm-txog cov khoom molding tsos flaws, xws li nozzle hlau kos duab, cov khoom to, cov khoom nto hlawv cov cim, carbon deposition dub me ntsis, filling shortage, uneven khoom hnyav, thiab pom lub rooj vag kab, kuj muaj ntau heev nyob rau hauv ntau lawm. Lub ntsiab yog vim li cas ntawm nozzle hlau kos duab thiab cov ntaub ntawv dripping yog ib tug siab heev nozzle taub hau kub, uas yog tshwm sim los ntawm tus maub los teem ib tug heev kub kub vim nozzle thermocouples tsis muaj peev xwm ntsuas qhov ntsuas kub tiag tiag. Kev kub ceev hauv zos ntawm cov neeg khiav dej num kub ua rau cov khoom kub hnyiab kub hnyiab thiab cov pa roj carbon deposition, thaum lub thermocouples 'qhov kub thiab txias saib xyuas thaj tsam qhov muag tsis pom kev ua rau cov ntaub ntawv nyoos khaws cia ntawm qhov kub siab rau lub sijhawm ntev, nrog rau thermal degradation thiab carbonization. Zuag qhia tag nrho qis kub khiav kub thiab tsis zoo yaj fluidity, uas tshwm sim los ntawm erroneous thermocouple zuag qhia tag nrho kub nrhiav kom tau thiab irrational kub tswj, yog ua rau filling scarcity thiab uneven filling.

Tsis tas li ntawd, nquag burnout ntawm cov cua kub ntsiab lus, kub tswj teeb liab tsis ua hauj lwm, kub khiav valve koob jamming, thiab lwm yam mechanical thiab hluav taws xob teeb meem nquag tshwm sim nyob rau hauv tiag tiag ntau lawm. Kev ua haujlwm tsis ruaj khov uas tau coj los ntawm qhov ntev - cov ntaub ntawv kub hloov pauv yog lub hauv paus ntawm feem ntau ntawm cov teeb meem no. Txhawm rau txhawm rau txhim kho kev ua haujlwm tsis raug cai, ua kom rov qab zoo li qub, thiab ua tiav qhov tsis zoo ntawm kev txhaj tshuaj molding khoom tshwm sim los ntawm kev ua haujlwm kub ua haujlwm, cov neeg ua haujlwm saib xyuas yuav tsum xub xyuas lub xeev ua haujlwm ntawm txhua pab pawg ntawm cov kub khiav thermocouples, ntsuas qhov ntsuas kub kom raug, tshem tawm qhov kub thiab txias tsis ua haujlwm zais kev phom sij, thiab tom qab ntawd xyuas cov qauv thiab Circuit Court faults.
