Kev txhawm rau niaj hnub siv thiab txhuam kom pom
Kev txhuam hniav zoo li qub thiab nrhiav kom pom Cov khoom siv txhuam hniav uas muag tau muag hauv khw yuav muab faib ua: loj, nruab nrab thiab tsawg, tsim los kho tu lub tshuab hluav taws xob, PCB Board, thiab lwm yam.
Kev txhuam txhuam txhuam hniav yog muab faib rau hauv: tuav kab, sib tsoo ob, txhua yam uas muaj qhov loj ntawm cov ntsiab lus, tsim los tu ntau yam khoom hauv hluav taws xob, PCB pawg thawj coj thiab lwm yam.
Qhov txhuam kuj raug faib ua peb hom: loj, nruab nrab, thiab me me, tsim kev tu ntau yam hauv hluav taws xob, PCB boards, thiab lwm yam.
Zoo li tus txhuam txhuam tshwj xeeb uas tsim los rau qee lub txheej txheem, xws li ntev txhuas txhuas los ntawm kev txhim kho rau cov yas luam yeeb.
ESD txhuam bristles muag muag thiab hnyav xaiv, yuav tsum ua raws li cov PCB cov khoom kom raug muab ntxuav los txiav txim rau cov kev cai, kev ntshai ntawm kev khawb ntawm kev siv cov plaub muag plaub txhuam xaiv, tab sis cov nyhuv ntxuav ntawm tawv txhuam dominant.
Txoj Kev Xeem:
Bristle deg tawv thiab txhuam tuav plaub hau tsis kam:
Kev sib tw kuaj taw tes rau qhov taw qhia thiab lub cev tsis muaj zog Tested electrode structure Loj: Colour electrode inch 63 mm ± 3 hli: Cov khoom siv hluav taws xob ua los ntawm stainless hlau lossis tooj liab; Cov khoom siv hluav taws xob Cov khoom siv cwj pwm 60 + 10 (Shore A grade), thickness 6 hli ± 1mm, nws lub cev ntim tsawg tshaj 500Ω: electrode hnyav 2.25 kg, 2.5 kg.
Saib ntawm qhov kev xeem ntawv qhov kev ntsuas
Thaum ntsuas qhov taw qhia-rau-taw kev, qhov khoom (khoom) yuav tsum tau muab tso rau ntawm ib qho insulating nto lossis tso rau hauv lub xeev qhov kev siv. Mesa ntom nti tsis ua haujlwm thiab ntim tsis ua haujlwm ntau dua li 1 x 10 ^ 13Ω, feem ntau, thiab lawv geometrical perimeter qhov loj tshaj cov khoom ntsuas 10 cm. Qhov kev ncua deb ntawm cov electrodes yog 300 hli. Hauv kev sim hauv av, qhov deb ntawm electrodes yog 900 mm txog 1000 hli.
Thaum kuaj qhov system ua haujlwm tsis zoo, txoj kev kuaj coj (hauv av) yuav tsum tau sim rau kev siv. Thaum lub sij hawm kev ntsuam xyuas engineering, lub electrode yog ntau tshaj 10 cm deb ntawm ntug ntawm cov khoom nyob rau hauv kev xeem.
Kev ntsuas qhov ntsuas rau qhov sib txawv ntawm qhov txawv:
2) Txhuam kom tsis muaj teeb meem hluav taws xob:
Cov kev sib txhuam ntawm kev sib txhuam los yog siv rau kev sib txhuam thiab qhov tsis sib chwv ntawm lub tshuab electrostatic voltage tau siv los ntsuas qhov kev siv hluav taws xob hluav taws xob. Kev sib txhuam hluav taws xob ntawm kev sib txhuam kev sib tw yog nyob rau hauv ib lub voj voog, muaj ib txoj kab uas muaj 50 mm mus txog 60 hli, ib qhov hnyav ntawm 1 kg, lub ntim ua rau ntau tshaj 1 x ^ 13 ohms, thiab ntaub ntim cov ntaub (piv rau daim duab 1): Thaum lub sij hawm qhov kev ntsuam xyuas, pib txhuam cov tshuab kev sib txhuam los ntawm kev txhuam cov hluav taws xob los ntawm cov khoom ntsuas, thiab qhov kev sib txhuam tsis sib npaug tau nres 20 zaug (zaug) sijhawm 20s), thiab qhov kev sib txhuam ntawm qhov kev sib txhuam ntawm kev sib txhuam tau ntsuas nrog ib hom non-contact type electrostatic voltmeter hauv 10 s.
