Dzidza nezve commutator repair

(1) Dunhu pfupi pakati pezvikamu zvevafambi
Iyo inonzi short circuit pakati pezvikamu zvevashambadzi zvinoreva kuti pane pfupi dunhu rekubatanidza pakati pezvikamu zviviri zviri pedyo zvevafambisi pane commutator. Dunhu pfupi pakati pezvikamu zvevafambi. Mhepo dzakakura dzichaonekwa pamusoro pemufambi; kana dunhu diki rakakomba, mhete yemoto inoitika pamusoro peiyo commutator.

Kugadziriswa kweiyo pfupi redunhu pakati pezvikamu zvevafambi kunotevera:
①Kucheneswa neslot yekuchenesa pepa Kana iyo armature winding ichipiswa nekuda kwepfupi-circuit kukanganisa, iyo yekukanganisa inogona kuwanikwa nenzira yekutarisa. Kuti uone kana kukanganisa kupfupi-kwedunhu kunoitika mukati memhepo kana pakati pezvikamu zvevafambi, musoro wewaya unomonereka wakabatana nechikamu chemufambi unofanirwa kubviswa, uye wozoshandisa cheki cheki kutarisa kana paine pfupi pfupi pakati pemufambi. zvikamu, senge pamusoro pechikamu chevafambi. Kana dunhu diki rawanikwa, kana spark ichipisa vanga, kazhinji shandisa slot yekuchenesa sheet inoratidzwa muMufananidzo 227 kukwenya machipisi esimbi mapfupi, hupfu hwebhurashi, zvinhu zvinoparadza, nezvimwewo, kusvikira cheki cheki chashandiswa. tarisa kuti hapana short-circuit. Uye shandisa mica powder uye shellac kana mica powder, epoxy resin uye polyamide resin (650) kusanganisa kuita paste, wozozadza grooves uye rega kuoma uye kuoma.
②Chenesa V-groove uye V-ring ye commutator block Kana iyo pfupi yedunhu pakati pemachipisi haigone kubviswa mushure mekunyatsobvisa kunze kwemarara pakati pemachipisi. Panguva ino, mufambisi anofanira kuparadzaniswa, uye V-groove neV-ring yeboka revatengesi inofanira kunyatsocheneswa. Usati wabvisa iyo commutator, peta pepa re elastic nehupamhi hwe 0.5 kusvika 1 mm kune yekunze denderedzwa ye commutator yekudzivirira, uye nyora nzvimbo yekukanganisa, uye wovhara iyo stacking die, uye ipapo Tora commutator parutivi. Uyezve tarisa kukanganisa pakati pezvikamu zvevashambadziri, pamusoro peV-groove uye V-ring, uye ita navo maererano nezvikanganiso zvakasiyana.
③ Kutsiviwa kwemica sheets pakati pemashiti Kana iyo pfupi dunhu pakati pemashiti isingagone kubviswa neiyo nzira iri pamusoro, chete mica sheets inogona kutsiviwa. Nzira yekutsiva iyo inter-chip mica flakes ndeyotevera.
Isa chikamu checommutator chiri pamusoro apa pandiro yakati sandara, tara mativi asina kunaka, wobva waisungirira nemhete yerabha, wobvisa simbi yewaya hoop kana waya yegirazi isina weft, uye shandisa chikamu chakapinza A chikamu chakafara chesaha. inopinzwa pakati pezvimedu zvakakanganisika, mushure mekusunungura, chimedu chine chinokanganisa chinoburitswa kunze, uye chimedu chitsva chemutanho cheiyo yakafanana neyakakanganiswa commutator chidimbu chinoiswa.
Mushure mekunge ndiro yemagetsi yatsiviwa, shandisa simbi hoops (ine kadhibhodhi gobvu mukati) kusungira boka rema commutator plate. Pisa iyo commutator block kusvika 165 ℃ ± 5 ℃, simbisa screws kekutanga, uye shandisa calibration rambi kutarisa kana dunhu pfupi pakati pemabhuroko rabviswa mushure mekutonhora. Kana iyo isina kubviswa, unofanira kunyatsotsvaga chikonzero chekukundikana kana kudzokorora basa riri pamusoro; kana dunhu pfupi pakati machipisi rabviswa, kuita gungano.
