1. Lub luag hauj lwm ntawm Induction Chev nyob rau hauv ib qho induction cua sov system
Ib tug raug induction cua sov system feem ntau muaj xws li:
Induction fais fab mov
Induction kauj
Txias qhov system
Workpiece positioning fixture
Tswj qhov system
Kev ntsuas kub ntsuas qhov system
Cov khoom siv hluav taws xob xa tawm nruab nrab - lossis siab - zaus hloov tam sim no rau lub kauj, tsim kom muaj qhov sib nqus sib nqus nyob ib puag ncig nws.
Thaum cov khoom siv hlau ua haujlwm nkag mus rau hauv qhov chaw sib nqus no, induced tam sim no yog tsim nyob rau hauv cov khoom. Hluav taws xob tsis kam ces converts qhov tam sim no mus rau hauv tshav kub.
Hauv cov ntsiab lus yooj yim, lub hwj chim muab lub zog, thaumlub induction coil txiav txim seb lub zog ntawd hloov mus rau hauv lub workpiece li cas.
Yog hais tias lub kauj yog tsim tsis zoo, txawm tias lub siab - lub zog hluav taws xob yuav raug kev txom nyem los ntawm:
Ua cua sov qeeb
Kev siv hluav taws xob siab
Hauv zos overheating
Qhov chaw cua sov tsis raug
