Cov qauv tsim ntawm Nruab Nrab-Frequency Direct Tam sim no Spot Vuam Tshuab

Medium-frequency direct tam sim no qhov chaw vuam tshuab yog cov cuab yeej tseem ceeb hauv ntau qhov kev lag luam, tshwj xeeb tshaj yog nyob rau hauv kev tsim khoom. Kev nkag siab txog lawv cov qauv yooj yim yog qhov tseem ceeb rau txhua tus neeg ua haujlwm nrog lossis nyob ib puag ncig cov tshuab no. Nyob rau hauv tsab xov xwm no, peb yuav delve rau hauv lub ntsiab Cheebtsam thiab functionalities ntawm ib tug nruab nrab-frequency direct tam sim no qhov chaw vuam tshuab.

1. Hloov pauv: Nyob rau hauv lub plawv ntawm lub tshuab lies lub transformer. Qhov kev tivthaiv no yog lub luag haujlwm rau kev hloov cov input alternating tam sim no (AC) mus rau hauv nruab nrab-frequency direct tam sim no (MFDC). MFDC yog qhov tseem ceeb rau kev ua tiav qhov tseeb thiab ua tau zoo ntawm qhov chaw vuam.
2. Rectifier: Txhawm rau kom muaj kev ruaj khov ntawm cov khoom siv tam sim no, lub rectifier yog ua haujlwm. Cov cuab yeej no hloov MFDC rau hauv daim ntawv ruaj khov haum rau kev siv vuam. Nws pab tswj cov vuam tam sim no zoo ib yam, uas yog qhov tseem ceeb rau qhov zoo tshaj plaws welds.
3. Tswj Vaj Huam Sib Luag: Cov tswj vaj huam sib luag yog qhov cuam tshuam los ntawm cov neeg ua haujlwm teeb tsa thiab kho cov vuam tsis xws li tam sim no, qhov hluav taws xob, thiab lub sijhawm vuam. Nws tso cai rau kev tswj kom meej, kom ntseeg tau tias welds ua tau raws li cov qauv kev xav tau.
4. Vuam Electrodes: Cov no yog cov khoom ntawm lub tshuab uas tuaj rau hauv kev sib cuag ncaj qha nrog lub workpiece. Feem ntau, muaj ob lub electrodes, ib qho chaw ruaj khov thiab ib qho txav tau. Thaum lawv tuaj ua ke, ib qho hluav taws xob hluav taws xob ua tiav, tsim cov cua sov uas xav tau rau kev vuam.
5. Txias System: Qhov chaw vuam ua kom muaj cua sov ntau, uas tuaj yeem ua rau lub tshuab puas. Txhawm rau tiv thaiv kom tsis txhob muaj cua sov, lub tshuab ua kom txias, feem ntau muaj dej lossis cua txias, tau muab tso rau hauv lub tshuab. Qhov system no pab tswj qhov kub thiab txias ua haujlwm.
6. Vuam Timer: Lub vuam timer yog lub luag haujlwm rau kev tswj xyuas lub sijhawm ntawm qhov vuam. Nws ua kom ntseeg tau tias cov electrodes nyob rau hauv kev sib cuag nrog lub workpiece rau lub sijhawm zoo tshaj plaws los tsim kom muaj zog thiab ruaj khov.
7. Kev nyab xeeb nta: Medium-frequency direct tam sim no qhov chaw vuam tshuab yog nruab nrog kev ruaj ntseg mechanisms xws li thaum muaj xwm ceev nres nyees khawm thiab overload tiv thaiv. Cov yam ntxwv no pab tiv thaiv kev sib tsoo thiab tiv thaiv ob lub tshuab thiab tus neeg teb xov tooj.

Nyob rau hauv xaus, ib tug nruab nrab-frequency ncaj tam sim no qhov chaw vuam tshuab lub hauv paus qauv muaj xws li cov khoom tseem ceeb xws li transformer, rectifier, tswj vaj huam sib luag, vuam electrodes, cua txias system, vuam timer, thiab kev nyab xeeb nta. Kev nkag siab txog yuav ua li cas cov khoom no ua haujlwm ua ke yog qhov tseem ceeb rau kev ua haujlwm ntawm lub tshuab kom muaj kev nyab xeeb thiab ua tau zoo, ua rau muaj qhov zoo ntawm qhov chaw welds hauv ntau daim ntawv thov kev lag luam.
