1. Rau perforation txiav, siv lub tshuab plasma txiav kom ntau li ntau tau los ntawm ntug. Qhov no yog los tiv thaiv qhov chaw tsis zoo xws li txiav nozzle. Nws pab siv lawv rau lub sijhawm ntev. Thaum siv lawv, ua ntej kho cov ntug ntawm lub workpiece thiab tom qab ntawd tig lub cuab yeej.
2. nquag arcing. Thaum txiav cov ntaub ntawv, qhov xwm txheej txiav tsis tau npaj ua ntej. Kev hloov kho tsis tu ncua ntawm kev txiav tsis tu ncua yuav ua rau nquag arcing, uas yuav ua rau kom poob ntawm nozzles thiab motors.
3. Lub nozzle yog overloaded, thiab qhov nce ntawm lub nozzle tam sim no tuaj yeem txhim kho qhov kev ua tau zoo, tab sis cov tam sim no ntau dhau yuav ua rau lub cev puas tsuaj. Qhov kev siv tam sim no ntawm lub nozzle yuav tsum tsis txhob raug ntaus rau tag nrho lub xeev, tsuas yog 95% ntawm qhov ua haujlwm tam sim no.
4. Yog hais tias qhov kev ncua deb me me los yog loj dhau, qhov kev ncua deb thiab txiav efficiency ntawm lub plasma tej tshuab yog tsis zoo correlated. Qhov kev ncua deb me me, qhov ua tau zoo dua. Tab sis lub teeb hluav taws xob uas me dhau yuav hnav lub taub hau txiav, yog li qhov kev ncua deb yuav tsum tau tswj kom tsim nyog. Nws yuav tsum raug sau tseg tias thaum tho, qhov kev ncua deb siv yuav tsum loj npaum li qhov ua tau.
5. Lub perforation thickness loj dhau, thiab qhov kev ncua deb ntawm lub tshuab txiav tuaj yeem perforate tau teev tseg, feem ntau yog ib nrab ntawm cov txiav thickness.
