Txhawm rau kom siv cov khoom siv hluav taws xob zoo dua, koj yuav tsum kawm ntxiv txog txhua yam ntawm cov khoom. Tib yam siv rau DC geared motors. Tom ntej no, cov chaw tsim khoom ntawm DC iav lub cev muaj zog yuav qhia txog kev sib hloov tshuab ntawm DC iav lub cev muaj zog.
Lub commutation defect ntawm DC geared lub cev muaj zog feem ntau txhais tau hais tias lub commutation spark nyob rau hauv lub txhuam tshaj tus qauv. Thaum lub sijhawm ua haujlwm ib txwm, qhov saum npoo ntawm lub commutator yuav tsum ci thiab yuav tsum muaj xim av tsaus nti cuprous oxide txij nkawm txheej. Cov txheej txheem kev saib xyuas tuaj yeem ua rau kom muaj kev sib cuag ntawm cov txhuam hniav thiab cov commutator thiab txo qhov luv luv tam sim no hauv qab txhuam. Tsis tas yuav tsum tswj lub commutator, thiab tom qab ntawd cov kev ua haujlwm ntawm lub commutator tuaj yeem txhim kho thiab cov pa taws tuaj yeem txo qis. Vim li cas cov txhuam hniav feem ntau yog cov cuab yeej hluav taws xob me me?
Piv txwv tias muaj cov xwm txheej hauv qab no nyob rau hauv ib puag ncig, qhov rov qab lub txim yuav nce ntxiv, uas yuav ua rau kom hnav cov txhuam hniav thiab commutator: tsis muaj oxygen txaus nyob rau hauv cov huab cua, thiab tsis muaj oxidation zoo tuaj yeem tsim rau saum npoo ntawm lub tshav kub exchanger. Membrane commutator; huab cua kub siab heev. Qhov saum npoo ntawm commutator tsis yooj yim los tsim cov oxide zaj duab xis. Cov huab cua muaj cov roj corrosive thiab plua plav, uas yuav ua rau cov oxide zaj duab xis ua rau puas tsuaj, ua rau muaj teeb meem hauv kev sib hloov thiab ua rau cov txhuam hniav ntxiv.
