Resistance chaw vuam yog ib txoj kev siv dav rau kev koom nrog cov khoom siv hlau hauv ntau qhov kev lag luam. Txawm li cas los xij, zoo li txhua lub tshuab, qhov chaw vuam tshuab tuaj yeem ntsib qhov yuam kev thiab ua haujlwm tsis zoo thaum lub sijhawm. Hauv tsab xov xwm no, peb yuav tham txog yuav ua li cas los ntsuas tus kheej ntawm qhov chaw vuam tshuab los txheeb xyuas thiab txheeb xyuas cov teeb meem tshwm sim.
Kev nyab xeeb ua ntej
Ua ntej peb delve rau hauv cov txheej txheem daws teeb meem, nws yog ib qho tseem ceeb uas yuav tsum tau hais txog qhov tseem ceeb ntawm kev nyab xeeb. Xyuas kom meej tias lub tshuab vuam raug txiav tawm ntawm lub zog hluav taws xob thiab tag nrho cov txheej txheem kev nyab xeeb tau ua raws li ua ntej sim ua qhov ntsuas tus kheej lossis kho. Cov iav kev nyab xeeb, nrog rau cov hnab looj tes vuam thiab lub kaus mom hlau, yuav tsum hnav txhua lub sijhawm thaum ua haujlwm no.
Kauj Ruam 1: Kev Ntsuam Xyuas Kev Pom Kev
Pib los ntawm kev ua kom pom kev zoo ntawm lub tshuab vuam. Tshawb xyuas cov kab xoob xoob xoob, cov xaim puas, lossis pom tseeb ntawm kev hnav thiab tsim kua muag. Xyuas kom tseeb tias tag nrho cov kev sib txuas muaj kev ruaj ntseg thiab tsis muaj qhov cuam tshuam pom hauv qhov chaw vuam.
Kauj Ruam 2: Kev kuaj xyuas hluav taws xob
- Fais fab mov: Paub meej tias lub hwj huam mov rau lub tshuab vuam yog ruaj khov. Kev hloov hluav taws xob tuaj yeem ua rau muaj teeb meem vuam. Siv ib lub multimeter los xyuas qhov voltage ntawm lub tshuab input.
- Hloov pauv: Tshawb xyuas lub vuam transformer rau cov cim qhia ntawm overheating, xws li discoloration los yog burnt tsw. Yog tias pom muaj teeb meem, qhov hloov pauv yuav xav tau hloov pauv.
- Tswj Vaj Huam Sib Luag: Tshawb xyuas lub vaj huam sib luag rau cov lej yuam kev lossis teeb ceeb toom. Nrog rau lub tshuab phau ntawv txhais lus cov lej yuam kev thiab ua qhov tsim nyog.
Kauj Ruam 3: Vuam Electrodes
- Electrode condition: Txheeb xyuas qhov xwm txheej ntawm vuam electrodes. Lawv yuav tsum tau huv si, tsis muaj khib nyiab, thiab muaj ib tug du, undamaged nto. Hloov cov electrodes uas hnav los yog puas lawm.
- Kev sib tw: Xyuas kom meej tias cov electrodes raug sib raug zoo. Misalignment tuaj yeem ua rau cov welds tsis sib xws. Kho lawv yog tias tsim nyog.
Kauj Ruam 4: Vuam Parameters
- Tam sim no thiab Sijhawm Teeb Meem: Xyuas kom tseeb tias lub tshuab vuam tam sim no thiab lub sijhawm teeb tsa tsim nyog rau cov khoom siv vuam. Nrog rau cov txheej txheem vuam specifications (WPS) rau kev taw qhia.
- Vuam Siab: Txheeb xyuas thiab kho qhov vuam siab raws li cov khoom tuab thiab hom. Lub siab tsis raug tuaj yeem ua rau cov welds tsis muaj zog lossis tsis tiav.
Kauj Ruam 5: Test Welds
Ua ib qho kev sim welds ntawm cov khoom seem uas zoo ib yam li cov workpieces koj yuav tau vuam. Tshawb xyuas qhov zoo ntawm cov welds, nrog rau lawv lub zog thiab cov tsos. Kho lub tshuab chaw raws li xav tau kom ua tiav qhov xav tau weld zoo.
Kauj Ruam 6: Cov ntaub ntawv
Sau tag nrho cov txheej txheem kuaj tus kheej, suav nrog txhua qhov kev hloov kho thiab cov txiaj ntsig ntawm kev ntsuas welds. Cov ntaub ntawv no yuav muaj txiaj ntsig zoo rau yav tom ntej siv thiab tshuaj ntsuam xyuas cov teeb meem yog tias lawv rov tshwm sim dua.
Kev saib xyuas tsis tu ncua thiab ntsuas tus kheej ntawm qhov chaw vuam tshuab yog qhov tseem ceeb los xyuas kom meej qhov zoo sib xws, zoo welds thiab tiv thaiv kom tsis txhob raug nqi poob. Los ntawm kev ua raws li cov kauj ruam no thiab ua raws li kev ceev faj txog kev nyab xeeb, koj tuaj yeem txheeb xyuas thiab daws cov teeb meem uas tshwm sim, ua kom koj txoj haujlwm vuam ua haujlwm zoo. Yog tias muaj teeb meem ntau dua, nws raug nquahu kom sab laj nrog tus kws tshaj lij lossis lub tshuab tsim khoom rau kev pab ntxiv.
