Motokari iri kupisa here? Ingogona zvibodzwa zvisere izvi!
Iyo mota inodiwa uye yakakosha inopa simba mukugadzirwa kwevanhu uye hupenyu. Mamota mazhinji anoburitsa kupisa kwakanyanya panguva yekushandiswa, asi nguva zhinji ivo havazive magadzirisirwo. Chakanyanya kuoma ndechekuti havazive chikonzero. Iko kukonzeresa kupisa kwemota kunofanirwa kuve kwekutanga kubatwa panguva yekushandiswa kwemota. Ngatitarisei zvikonzero zvinowanzoitika nei mota ichipisa zvakanyanya. 1. Mhepo yemhepo pakati pe stator uye rotor yemota idiki kwazvo, izvo zvinogona kutungamirira nyore kudhumhana pakati pe stator ne rotor. Mumamotor epakati uye madiki, iro gap remhepo rinowanzo 0.2mm kusvika 1.5mm.Kana iyo gap yemhepo yakakura, iyo excitation ikozvino inodiwa kuti ive yakakura, nekudaro ichikanganisa simba remota; kana mhepo yepamhepo idiki, rotor inogona kukwiza kana kudhumhana.Kazhinji, nekuda kwekunyanya kushivirira kwekutakura uye kupera uye kushanduka kwegomba remukati revhavha yekupedzisira, mbezo dzakasiyana dzemuchina base, chivharo chekupedzisira uye rotor zvinokonzeresa kutsvaira, izvo zvinokonzeresa nyore mota kupisa kana kutopisa.Kana kutakura kunowanikwa kuti kwakasakara, inofanira kuchinjwa munguva, uye chivharo chekupedzisira chinofanira kuchinjwa kana kubvongodzwa. Nzira yekurapa iri nyore ndeyekuisa chivharo chekupedzisira. 2. Kudengenyeka kusina kujairika kana ruzha rwemota zvinogona kuita kuti mota iwedzere kupisa Mamiriro ezvinhu aya ndeekuzunguzika kunokonzerwa nemota pachayo, mazhinji ayo ari nekuda kwekusagadzikana kweiyo rotor, kutadza kubereka, yakabhenda shaft, dzakasiyana shaft nzvimbo dzevhavha yekupedzisira, chigadziko chemuchina, uye rotor, yakasununguka fasteners, kana kusaenzana. nheyo yekuiswa kwemotokari, uye kuiswa kusina kukodzera Inogona kukonzerwa nekufambisa kubva kumagumo emagetsi, iyo inofanira kubviswa maererano nemamiriro ezvinhu chaiwo. 3. Kana kubereka kusingashande zvakanaka, zvechokwadi kuchaita kuti motokari inopisa. Kana bearing iri kushanda zvakajairika zvinogona kutongwa nekunzwa uye tembiricha ruzivo. Iwe unogona kutarisa magumo ekubereka nemaoko ako kana thermometer kuti uone kana tembiricha yayo iri mukati meyakajairika; iwe unogona zvakare kushandisa tsvimbo yekuteerera (tsvimbo yemhangura) kubata bhokisi rekutakura. Kana iwe ukanzwa ruzha rwekuita, zvinoreva kuti bhora rimwe kana akati wandei rinogona kupwanywa. Kuridza ruzha, zvinoreva kuti mafuta ekuzora ekutakura haana kukwana, uye mota inofanirwa kushandura girisi yekuzora maawa ega ega e3,000 kusvika ku5,000 maawa. 4. Iyo magetsi emagetsi akawandisa, iyo yekukurudzira ikozvino inowedzera, uye mota ichapisa Yakawandisa voltage inogona kukanganisa iyo motor insulation, ichiisa panjodzi yekuparara.Kana magetsi emagetsi akanyanya kuderera, iyo electromagnetic torque inoderera. Kana iyo torque yekutakura isingadzike uye kumhanya kwerotor kwakadzikira, kutsvedza kwakawedzera kuchaita kuti mota iwande uye kupisa. Kuremerwa kwenguva refu kuchakanganisa hupenyu hwemota.Kana iyo matatu-phase voltage iri asymmetrical, ndiko kuti, kana voltage yeimwe chikamu yakakwira kana yakaderera, ikozvino yeimwe chikamu ichave yakakura kwazvo, uye mota ichapisa. Panguva imwecheteyo, torque ichaderera uye "humming" inzwi richabudiswa. Mushure menguva refu, kupemha kunozokuvadzwa. Muchidimbu, zvisinei kuti voltage yakawandisa, yakaderera kana kuti voltage iri asymmetrical, ikozvino ichawedzera, uye mota ichapisa nekukuvadza mota.Naizvozvo, zvinoenderana nechiyero chenyika, shanduko yemagetsi emagetsi emota haifanirwe kudarika ± 5% yehuwandu hwakayerwa, uye simba rekubuda remota rinogona kuchengetedza kukosha kwakayerwa.Iko magetsi emagetsi emagetsi haabvumirwi kudarika ± 10% yehuwandu hwehuwandu, uye mutsauko pakati pematatu emagetsi emagetsi emagetsi haafaniri kudarika ± 5% yehuwandu hwehuwandu. 5. Kupeta dunhu diki, kutendeuka-ku-kutendeuka pfupi dunhu, chikamu-ku-chikamu chipfupi chedunhu uye mhepo yakavhurika yedunhu. Mushure mekuvharwa pakati pewaya mbiri dziri padyo mumhepo yakuvadzwa, ma conductor maviri anogunzvana, iyo inonzi mhepo ipfupi pfupi.Mamhepo mapfupi emhepo anoitika mumhepo yakafanana anonzi turn-to-turn short circuits.Dunhu diki rinomonereka rinoitika pakati pezvikamu zviviri zvinotenderedza zvinonzi phase-to-phase short circuit.Hazvina mhosva kuti ndeipi, ichawedzera ikozvino yechikamu chimwe kana nhanho mbiri, kukonzera kupisa kwenzvimbo, uye zera iyo insulation yekukuvadza mota.Winding open circuit (Winding open circuit) zvinoreva kutadza kukonzerwa ne stator kana rotor winding yemotor iri kuputswa kana kuvhuvhuta.Ingave iri pfupi redunhu kana rakavhurika redunhu remhepo, rinogona kukonzera mota kupisa kana kutopisa.Nokudaro, inofanira kuvharwa pakarepo mushure mokunge izvi zvaitika. 6. Izvo zvinhu zvinodonhedza mumotor, izvo zvinoderedza kuvharika kwemota, nekudaro kuderedza inobvumidzwa tembiricha kukwira kwemota. Kana zvinhu zvakasimba kana guruva rikapinda mumotor kubva mubhokisi rekusangana, rinosvika pamukaha wemhepo pakati pe stator uye rotor yemota, zvichiita kuti mota itsvairwe, kudzamara kuvharirwa kwemotor winding kwapera, uye mota yakuvadzwa. kana kuraswa.Kana mvura uye gasi midhiya ikanyudza mumotor, inokonzeresa zvakananga kuti insulation yemota idonhe uye ifambe.General liquid uye gasi leakage ine zvinotevera zviratidzo: (1) Kudonhedza kwemidziyo yakasiyana-siyana uye mapaipi ekutakura, kuvuza kwepombi yemuviri zvisimbiso, midziyo yekutsvaira uye pasi, nezvimwe. (2) Mushure mekunge mafuta emuchina adonha, anopinda mumotokari kubva pakakoromoka rebhokisi rekumberi. (3) Chisimbiso chemafuta chechidzikisira chakabatana nemota chakapfekwa, uye oiri yekuzora yemuchina inopinda nedivi remota shaft. Mushure mekuunganidza mukati memotor, inonyungudutsa iyo motor insulation varnish, iyo inoderedza zvishoma nezvishoma kushanda kwemota. 7. Inenge hafu yemoto inopisa inokonzerwa nekushayikwa kwechikamu chekushanda kwemotokari Kushaikwa kwechikamu kunowanzoita kuti mota ikundikane kumhanya kana kukurumidza kunonoka mushure mekutanga, kana kune "humming" inonzwika kana kutenderera kusina simba uye ikozvino inowedzera.Kana mutoro uri pa shaft usingashanduki, motokari inoremerwa zvakanyanya, uye stator yemazuva ano ichasvika 2 nguva iyo yakarongwa kukosha kana kunyange yakakwirira.Iyo mota ichapisa kana kutopisa mukati menguva pfupi.Zvikonzero zvikuru zvekushaikwa kwechikamu chekushanda ndeizvi: (1) Kana imwe nhanho yetambo yemagetsi ikagurwa nekuda kwekutadza kweimwe midziyo, mamwe matatu-chikamu midziyo yakabatana netambo inomhanya isina chikamu. (2) Imwe nhanho yedunhu rinotyora kana contactor yabuda muchikamu nekuda kwe bias voltage burnout kana kusabatana zvakanaka. (3) Kushaikwa kwechikamu chinokonzerwa nekuchembera uye kupfeka kwemutsetse unouya wemota. (4) Imwe-chikamu mhepo yemotokari yakaputsika, kana imwe-chikamu chekubatanidza mubhokisi rejunction yakasununguka. 8. Zvimwe zvisiri zvemagetsi uye kukundikana kwemagetsi zvinokonzera Kukwira kwekushisa kwemota kunokonzerwa nedzimwe dzisiri-mechini uye kutadza kwemagetsi kunogonawo kutungamira mukutadza kwemota mumatambudziko akaomarara.Kana iyo ambient tembiricha yakakwira, mota isina fan, fan haina kukwana, kana chivharo chefani chisipo.Muchiitiko ichi, zvinodikanwa kumanikidza kutonhora kuti uone kufefetedza kana kutsiva fan blades, zvikasadaro kushanda kwakajairika kwemota hakugone kuvimbiswa. Kupfupisa, kuti ushandise nzira chaiyo yekugadzirisa kukanganisa kwemotokari, zvinodikanwa kuti uzive hunhu uye zvikonzero zvekukanganisa kwakajairika mota, kubata zvakakosha, uye kugara uchiongorora uye kugadzirisa.Nenzira iyi, kutsauka kunogona kudziviswa, nguva inogona kuchengetedzwa, zvikanganiso zvinogona kubviswa nekukurumidza sezvinobvira, uye mota inogona kunge iri mune yakajairika inoshanda mamiriro.Kuti uve nechokwadi chekugadzirwa kwakajairika kwemusangano.
