Kev sib tsoo tshwm sim los ntawm txhuam hnav yog ib qho teeb meem tshwm sim hauv kev ua haujlwm ntawm DC motors lossis lub qhov txhab rotor asynchronous motors. Sparks tsis tsuas yog ua kom cov txhuam hniav thiab cov commutators / plam rings, tab sis kuj tsim hluav taws xob cuam tshuam thiab tej zaum yuav ua rau muaj kev nyab xeeb. Morteng txheeb xyuas cov laj thawj ntawm qhov teeb meem los ntawm cov hauv qab no:
Kev ua tau zoo: ceev txhuam hnav thiab hloov tsis tu ncua; pom sparks thaum lub sij hawm ua hauj lwm, txawm burning nto ntawm lub nplhaib plam; txhuam dhia los yog vibration.
Lub ntsiab mechanical ua rau sparks:
Kev txhuam txhuam tsis zoo: Qhov no yog ib qho ua rau ntau tshaj plaws.
Lub caij nplooj ntoos hlav tsis txaus: Caij nplooj ntoos hlav hnub nyoog, deformation, los yog thawj qhov chaw siab uas qis dhau tuaj yeem ua rau muaj kev sib cuag tsis txaus ntawm cov txhuam thiab cov commutator / plam nplhaib, ua rau kev sib cuag, ua rau cov ntsiab lus sib tiv tauj kom sov, thiab ua rau cov nplaim taws yuav tshwm sim thaum lub sij hawm tam sim no commutation los yog micro-vibrations.
Lub caij nplooj ntoos hlav siab dhau: Thaum lub siab ntau dhau tuaj yeem txhim kho kev sib cuag, nws ua rau muaj kev sib txhuam thiab hnav ntau dua, ua rau cov cua sov thiab cov pa roj carbon ntau dhau, thiab tuaj yeem ua rau cov oxide zaj duab xis rau ntawm qhov chaw sib txuas, yog li ua kom tawg.
Cov txhuam hniav daig hauv cov txhuam hniav: Deformation ntawm tus txhuam hniav, sib sau cov nyiaj, cov txhuam tsis sib haum, lossis hnav ntawm ob sab ntawm cov txhuam hniav tuaj yeem ua rau lawv txav mus rau hauv cov txhuam hniav, tiv thaiv kom tsis txhob ua raws li qhov me me vibrations lossis eccentricity ntawm commutator / plam rings, ua rau tsis ruaj tsis khov.
Qhov chaw tsis xws luag ntawm lub commutator / plam nplhaib: Nto irregularities (scratches, pits, burn marks), ntau ellipticity / eccentricity, protruding mica nplooj (commutator), los yog ntau tshaj axial txav yuav cuam tshuam tus du, nruam zawv zawg sib cuag ntawm txhuam thiab rotating nto.
Kev txhim kho txhuam tsis raug: Txhuam tsis raug ntsia ntawm qhov chaw nruab nrab lossis ntawm lub kaum sab xis.
Ntau lub tshuab kev co: kev vibration los ntawm lub cev muaj zog nws tus kheej los yog cov khoom siv tsav yog kis mus rau qhov chaw txhuam hniav, ua rau txhuam txhuam.
Kev hnav tsis sib xws ntawm commutator/slip nplhaib: Ua rau qhov tsis sib xws.
