Nyob rau hauv tus txheej txheem ntawm kev siv CNC system ntawm kev lag luam tshuab cov cuab yeej, nws yog ib qho tsim nyog los txhim kho nws txoj kev tiv thaiv kev cuam tshuam. Cov txheej txheem muaj xws li: txwv tsis pub lub suab nrov, thaiv cov suab nrov kis tau tus mob, thiab txhim kho lub hauv paus ntawm CNC system. Kev xyaum tau ua pov thawj tias hauv kev ua haujlwm, siv cov txheej txheem no hloov pauv raws li qhov xwm txheej tshwj xeeb tuaj yeem txhim kho qhov muaj peev xwm tiv thaiv kev cuam tshuam ntawm NC system ntawm kev lag luam tshuab dhos.
1, Tshem tawm lub suab nrov cuam tshuam
Lub suab nrov ntawm CNC system feem ntau suav nrog suab nrov sab hauv thiab sab nraud. Rau cov suab nrov sab hauv, sim tshem tawm nws; Lub suab nrov sab nraud tsis tuaj yeem tshem tawm ncaj qha, tab sis nws tuaj yeem zam tau ntau li ntau tau. Hauv kev tsim khoom, kev ntsuas los tshem tawm cov suab nrov sab hauv thiab sab nraud feem ntau suav nrog cov hauv qab no:
1. Tshem tawm qhov kev xav ntawm kev hloov pauv
Hloov inductive loads xws li relays, contactors thiab motors yuav tsim high surge voltage, thiab nws mem tes zog yuav ua rau puas semiconductor li. Qhov xwm txheej no tuaj yeem cuam tshuam los ntawm kev siv cov diodes sib luag lossis txuas RC nqus Circuit Court. Lub DC relay coils ntawm lub tshuab cuab yeej lub cev muaj zog thiab cov cuab yeej hluav taws xob so lub cev muaj zog txuas nrog rau tib lub sijhawm nrog diodes, thiab RC absorption circuit txuas nrog rau tib lub sijhawm nrog lub contactor coil thiab lub cev muaj zog winding. Kev xyaum tau ua pov thawj tias cov nyhuv inhibition ntawm txoj kev no tseem pom tseeb heev. Tsis tas li ntawd, thyristor xoom hla kev hloov pauv tuaj yeem siv los hloov AC contactor, uas tuaj yeem tshem tawm cov suab nrov tsis tu ncua.
2. Tshem tawm DC fais fab mov suab nrov
Lub hwj chim mov ntawm feem ntau economical tshuab dhos CNC system computers yog tsim los ntawm peb lub davhlau ya nyob twg integrated voltage regulators. Lub Circuit Court yog yooj yim thiab txhim khu kev qha, tab sis lub peev xwm los suppress lub hwj chim mov suab nrov los ntawm sab nraud AC fais fab tuag yog tsis muaj zog heev. Txhawm rau txhawm rau cuam tshuam ntawm cov suab nrov, ntau theem lim Circuit Court tuaj yeem txiav txim siab los txhawb kev lim dej. Kev sib txuas cov kab lim ntawm cov tswv yim ntawm AC fais fab mov tuaj yeem tsis tsuas yog cuam tshuam cov tiam ntawm cov suab nrov nrov thiab hom suab nrov, tab sis kuj tseem siv tau rau cov suab nrov sab nraud.
2, Optimize Circuit Court tsim
Feem ntau cov kev lag luam CNC tshuab siv ib leeg-chip khoos phis tawj, uas yuav tsum tau nthuav tawm qee qhov txuas txuas txuas txuas. Lub input chaw nres nkoj ntawm ib leeg-chip computers yuav tsum tau ntxiv nrog rub resistors, tshwj xeeb tshaj yog lub interrupt chaw nres nkoj yuav tsum tau ntxiv nrog ib tug thiab shaping circuits, thiab cov zis chaw nres nkoj yuav tsum tau ntxiv nrog tam sim no tsav tsheb los txhim khu lub anti-interrupt peev ntawm cov tswv yim thiab tso zis ports. .
