(1) Electromagnetic yam: thaum lub zog reactive lossis excitation tam sim no raug kho, lub txim ntawm cov pa roj carbon txhuam tau pom tseeb hloov, thiab thaum lub exciter yog commutated, cov pa roj carbon txhuam tsis zoo nrog lub commutator, kev tiv thaiv kev sib cuag loj dhau. , thiab oxide zaj duab xis thickness ntawm lub commutator los yog lub nplhaib plam tsis sib npaug, ua rau tam sim no kev faib tawm ntawm cov pa roj carbon txhuam tsis sib npaug: los yog qhov kev hloov pauv ntawm lub sijhawm tam sim ntawd, thiab tam sim ntawd luv luv Circuit Court ua rau qhov txawv txav ntawm cov commutator los xij; overload thiab imbalance ntawm chav tsev; Kev xaiv cov txhuam hniav yog qhov tsis tsim nyog, qhov sib nrug ntawm cov txhuam hniav tsis sib xws, qhov zoo ntawm cov txhuam hniav yog qhov teeb meem, thiab lwm yam.
(2) Mechanical yam: qhov nruab nrab ntawm lub commutator tsis yog lawm, lub rotor yog unbalanced, lub vibration ntawm lub chav tsev yog loj, lub rwb thaiv tsev ntawm lub commutator pieces yog convex los yog lub commutator yog protruding, cov pa roj carbon txhuam hniav yog tsis du. , los yog nto ntawm lub commutator yog ntxhib thiab kev sib cuag tsis zoo; Qhov saum npoo ntawm lub commutator tsis huv, thiab qhov sib txawv ntawm huab cua nyob rau hauv tus ncej thim rov qab tsis tsim nyog; Lub caij nplooj ntoos hlav siab ntawm cov txhuam hniav tsis sib xws lossis qhov loj me tsis haum; Cov txhuam hniav yog xoob dhau ntawm txhuam txhuam thiab dhia, lossis cov txhuam hniav yog nruj heev thiab tau daig hauv txhuam txhuam; Los yog txhuam txhuam thiab qhov chaw ntawm lub nplhaib sau tsis yog ntsug, thiab lwm yam.
(3) chemical yam tseem ceeb: chav tsev khiav hauv cov roj corrosive, los yog chav tsev khiav hauv qhov chaw tsis muaj oxygen, qhov chaw ntawm lub commutator thiab cov pa roj carbon txhuam tau raug puas tsuaj los ntawm cov txheej txheem ntawm cov tooj liab oxide zaj duab xis, cov commutation. tau tsim, qhov kwv yees tawm ntawm qhov tsis sib haum xeeb ntawm kev sib hloov tsis muaj lawm, lub commutator spark intensifies nyob rau hauv tus txheej txheem ntawm kev hloov kho cov oxide zaj duab xis rau ntawm qhov chaw sib cuag, thiab cov pa roj carbon txhuam thiab cov commutator muaj kuab paug.
