K\u0101 r\u012bkoties, ja s\u016bk\u0146a motora zudumi ir p\u0101r\u0101k lieli?<\/h2>\n
    \n
  1. Main\u012bgie zudumi main\u0101s atkar\u012bb\u0101 no slodzes, tostarp statora pretest\u012bbas zudumi (vara zudumi), rotora pretest\u012bbas zudumi un suku pretest\u012bbas zudumi.<\/li>\n
  2. Fiks\u0113tie zudumi nav atkar\u012bgi no slodzes, ieskaitot serdes zudumus un meh\u0101niskos zudumus. Dzelzs zudumus veido ar\u012b hister\u0113zes zudumi un virpu\u013cstr\u0101vas zudumi, kas ir proporcion\u0101li sprieguma kvadr\u0101tam, un hister\u0113zes zudumi ir apgriezti proporcion\u0101li frekvencei.<\/li>\n
  3. Citi izkliedes zudumi ir meh\u0101niskie zudumi un citi zudumi, tostarp gult\u0146u berzes zudumi un v\u0113ja pretest\u012bbas zudumi, ko rada ventilatoru, rotoru utt. rot\u0101cija.<\/li>\n<\/ol>\n

    Pieci pas\u0101kumi motora zudumu samazin\u0101\u0161anai:<\/h2>\n

    Pirmk\u0101rt, statora zudumi: Galven\u0101s metodes, k\u0101 samazin\u0101t motora statora I^2R zudumus, ir \u0161\u0101das:<\/p>\n

      \n
    1. Palieliniet statora slota \u0161\u0137\u0113rsgriezuma laukumu. Ja statora \u0101r\u0113jais diametrs ir t\u0101ds pats, palielinot statora spraugas \u0161\u0137\u0113rsgriezuma laukumu, samazin\u0101sies magn\u0113tisk\u0101s \u0137\u0113des laukums un palielin\u0101sies zobu magn\u0113tiskais bl\u012bvums.<\/li>\n
    2. palielin\u0101t statora slota pilno slotu \u0101trumu, \u0161is zemsprieguma mazais motora efekts ir lab\u0101ks, lab\u0101k\u0101s tinuma un izol\u0101cijas izm\u0113ra piem\u0113ro\u0161ana, liela stieples \u0161\u0137\u0113rsgriezuma laukums var palielin\u0101t statora slota \u0101trumu.<\/li>\n
    3. p\u0113c iesp\u0113jas sa\u012bsin\u0101t statora tinuma gala garumu, statora tinuma gala zudumi veido 1\/4 ~ 1\/2 no kop\u0113jiem tinuma zudumiem, samazinot tinuma gala garumu, var uzlabot motora efektivit\u0101ti. Eksperimenti r\u0101da, ka gala garums samazin\u0101s par 20% un zudumi par 10%.<\/li>\n<\/ol>\n

      3, samaziniet harmonikas, uzlabojot statora tinumu konstrukciju.<\/p>\n

      4, uzlabot rotora gropes dizainu un koordin\u0101ciju, lai samazin\u0101tu harmonikas, palielin\u0101t fiks\u0113to un rotora zobu slotu, rotora gropes formas dizainu sl\u012bp\u0101 slot\u0101, izmantot s\u0113rijas sinusoid\u0101lo tinumu, izklied\u0113tu tinumu un \u012bsa att\u0101luma tinumu var iev\u0113rojami samazin\u0101t augstas harmonikas; T\u0101 ir efekt\u012bva metode, lai samazin\u0101tu papildu izkliedes zudumus, izmantojot magn\u0113tisko gropes dub\u013cus vai magn\u0113tisko gropes \u0137\u012bli, nevis tradicion\u0101lo izol\u0113to gropes \u0137\u012bli un aizpildot motora statora serdes gropi ar magn\u0113tiskajiem gropes dub\u013ciem.<\/p>\n

      Tre\u0161k\u0101rt, v\u0113ja berzes zudumi: v\u0113ja berzes zudumi veido aptuveni 25% no kop\u0113jiem motora zudumiem, kam j\u0101piev\u0113r\u0161 pien\u0101c\u012bga uzman\u012bba. V\u0113ja berzes zudumus galvenok\u0101rt rada gult\u0146i un bl\u012bv\u0113jumi, un tos var samazin\u0101t ar \u0161\u0101diem pas\u0101kumiem:<\/p>\n

      1, samazin\u0101t v\u0101rpstas izm\u0113ru, bet izpild\u012bt izejas griezes momenta un rotora dinamikas pras\u012bbas.<\/p>\n

      2, augstas efektivit\u0101tes gult\u0146u izmanto\u0161ana.<\/p>\n

      3, izmantojiet efekt\u012bvu e\u013c\u013co\u0161anas sist\u0113mu un sm\u0113rvielu.<\/p>\n

      4, pie\u0146emt modernu bl\u012bv\u0113\u0161anas tehnolo\u0123iju.<\/p>\n

      Ceturtk\u0101rt, rotora zudumi: motora rotora I^2R zudumi galvenok\u0101rt ir saist\u012bti ar rotora str\u0101vu un rotora pretest\u012bbu, un attiec\u012bg\u0101s ener\u0123ijas taup\u012b\u0161anas metodes galvenok\u0101rt ir:<\/p>\n

      1, samazin\u0101t rotora str\u0101vu, ko var apl\u016bkot no diviem aspektiem - sprieguma un motora jaudas koeficientu uzlabo\u0161anas.<\/p>\n

      2, palieliniet rotora slota \u0161\u0137\u0113rsgriezuma laukumu.<\/p>\n

      3, samazin\u0101t rotora tinuma pretest\u012bbu, piem\u0113ram, izmantojot biezu stiepli un zemas pretest\u012bbas materi\u0101lus, tas ir noz\u012bm\u012bg\u0101k maziem motoriem, jo mazie motori parasti ir lieti alum\u012bnija rotori, ja izmanto lietus vara rotoru, motora kop\u0113jos zaud\u0113jumus var samazin\u0101t par 10% l\u012bdz 15%, bet \u0161odienas lietais vara rotors prasa augstu ra\u017eo\u0161anas temperat\u016bru un tehnolo\u0123ija nav populariz\u0113ta, t\u0101 izmaksas ir augst\u0101kas nek\u0101 lietais alum\u012bnija rotors 15% l\u012bdz 20%.<\/p>\n

      Pieci, dzelzs serdes zudums: Motora dzelzs zudumus var samazin\u0101t ar \u0161\u0101diem pas\u0101kumiem:<\/p>\n

      1, samazin\u0101t magn\u0113tisko bl\u012bvumu, palielin\u0101t serdes garumu, lai samazin\u0101tu magn\u0113tisk\u0101 indukcijas bl\u012bvumu, bet palielin\u0101s motora izmantot\u0101s dzelzs daudzums.<\/p>\n

      2, samazin\u0101t dzelzs mikrosh\u0113mas biezumu, lai samazin\u0101tu induc\u0113t\u0101s str\u0101vas zudumu, piem\u0113ram, izmantojot auksti velm\u0113tu sil\u012bcija t\u0113raudu karsti velm\u0113tas sil\u012bcija t\u0113rauda loksnes viet\u0101, var samazin\u0101t sil\u012bcija t\u0113rauda loksnes biezumu, bet pl\u0101n\u0101 dzelzs serdes loksne palielin\u0101s dzelzs mikrosh\u0113mu skaitu un motora ra\u017eo\u0161anas izmaksas.<\/p>\n

      3, labas magn\u0113tisk\u0101s caurlaid\u012bbas auksti velm\u0113tas sil\u012bcija t\u0113rauda loksnes izmanto\u0161ana, lai samazin\u0101tu hister\u0113zes zudumus.<\/p>\n

      4, augstas veiktsp\u0113jas dzelzs skaidu izol\u0101cijas p\u0101rkl\u0101juma izmanto\u0161ana.<\/p>\n

      5, termisk\u0101 apstr\u0101de un ra\u017eo\u0161anas tehnolo\u0123ija, atliku\u0161ais spriegums p\u0113c dzelzs mikrosh\u0113mas apstr\u0101des nopietni ietekm\u0113s motora zudumu, sil\u012bcija t\u0113rauda loksnes apstr\u0101di, grie\u0161anas virzienu, trieciena b\u012bdes spriegums uz serdes zudumu ir liel\u0101ks. Grie\u0161ana gar sil\u012bcija t\u0113rauda loksnes velm\u0113\u0161anas virzienu un sil\u012bcija t\u0113rauda caurumo\u0161anas loksnes termisk\u0101 apstr\u0101de var samazin\u0101t 10% l\u012bdz 20% zudumus.<\/p>\n

      Uztur\u0113\u0161anas metodes<\/span><\/b><\/strong><\/h2>\n

      Profesion\u0101ls motoru apkopes un remonta centrs Motoru apkopes process: Statora un rotora t\u012br\u012b\u0161ana - Oglek\u013ca suku vai citu komponentu nomai\u0146a - Vakuuma F l\u012bme\u0146a spiediena iegremd\u0113\u0161anas kr\u0101sas - \u017d\u0101v\u0113\u0161ana - Dinamisk\u0101 l\u012bdzsvara kalibr\u0113\u0161ana.1. Lieto\u0161anas vide regul\u0101ri j\u0101uztur sausa, motora virsma j\u0101uztur t\u012bra, un gaisa iepl\u016bde nedr\u012bkst b\u016bt aizsprostota ar putek\u013ciem, \u0161\u0137iedr\u0101m utt. 2. Ja motora termisk\u0101 aizsardz\u012bba nep\u0101rtraukti darbojas, j\u0101nosaka, vai k\u013c\u016bmes c\u0113lonis ir motora p\u0101rslodze vai p\u0101r\u0101k maza aizsardz\u012bbas ier\u012bces iestat\u012bjuma v\u0113rt\u012bba. Tikai p\u0113c k\u013c\u016bmes nov\u0113r\u0161anas var s\u0101kt motora ekspluat\u0101ciju.3. Nodro\u0161iniet labu motora e\u013c\u013co\u0161anu ekspluat\u0101cijas laik\u0101. Tipisks elektromotors j\u0101e\u013c\u013co vai j\u0101nomaina p\u0113c aptuveni 5000 stundu darb\u012bbas. Ja ekspluat\u0101cijas laik\u0101 tiek konstat\u0113ts, ka gult\u0146i ir p\u0101rkarsu\u0161i vai e\u013c\u013co\u0161ana pasliktin\u0101s, savlaic\u012bgi j\u0101nomaina hidraulisk\u0101s sist\u0113mas sm\u0113rviela. Nomainot sm\u0113re\u013c\u013cu, vec\u0101 sm\u0113re\u013c\u013ca j\u0101no\u0146em, un gult\u0146u un gult\u0146u v\u0101ku e\u013c\u013cas rievas j\u0101not\u012bra ar benz\u012bnu. P\u0113c tam 1\/2 (2 poliem) un 2\/3 (4, 6 un 8 poliem) dobuma starp gult\u0146a iek\u0161\u0113jo un \u0101r\u0113jo gredzenu aizpildiet ar ZL-3 litija sm\u0113rvielu. 4. Kad beidzas gult\u0146u kalpo\u0161anas laiks, iev\u0113rojami palielin\u0101sies motora darb\u012bbas vibr\u0101cija un troksnis. Kad gult\u0146u radi\u0101lais kl\u012brenss sasniedz \u0161\u0101das v\u0113rt\u012bbas, gult\u0146i j\u0101nomaina. 5. Demont\u0113jot motoru, rotoru var no\u0146emt vai nu no v\u0101rpstas pagarin\u0101t\u0101 gala, vai no nepagarin\u0101t\u0101 gala. Ja nav nepiecie\u0161ams no\u0146emt ventilatoru, rotoru ir \u0113rt\u0101k no\u0146emt no v\u0101rpstas pagarin\u0101juma gala. No\u0146emot rotoru no statora, j\u0101nov\u0113r\u0161 statora tinuma vai izol\u0101cijas boj\u0101jumi. 6. Nomainot tinumu, ir j\u0101re\u0123istr\u0113 s\u0101kotn\u0113j\u0101 tinuma forma, izm\u0113rs, vijumu skaits, stieples diametrs utt. Ja \u0161ie dati ir pazaud\u0113ti, tie j\u0101ieg\u016bst no ra\u017eot\u0101ja. Patva\u013c\u012bga ori\u0123in\u0101l\u0101s konstrukcijas tinuma nomai\u0146a bie\u017ei vien pasliktina vienu vai vair\u0101kus motora darb\u012bbas aspektus un pat padara to nelietojamu.<\/p>","protected":false},"excerpt":{"rendered":"
