1. Mhepo yemhepo pakati pe stator uye rotor yemotokari iduku zvikuru, izvo zviri nyore kukonzera kudhumhana pakati pe stator uye 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 kweiyo yakakomba kunze-kwe-kushivirira kwekutakura uye kupera uye kushandurwa kwegomba remukati revhavha yekupedzisira, akasiyana mbezo yemuchina base, chivharo chekupedzisira uye rotor zvinokonzeresa kutsvaira, izvo zvinogona kukonzera nyore. injini kupisa kana kutopisa.Kana kutakura kunowanikwa kuti kwakasakara, inofanira kuchinjwa munguva, uye chivharo chekupedzisira chinofanira kuchinjwa kana kubvongodzwa.Nzira yekurapa iri nyore ndeyekuisa sleeve pachivharo chekupedzisira.
2. Kudengenyeka kusina kujairika kana ruzha rwemota zvinogona kukonzera kupisa kwemota zviri nyore
Mamiriro ezvinhu aya ndeekuzunguzika kunokonzerwa nemota pachayo, mazhinji ayo anokonzerwa nekusasimba kwesimba rerotor, pamwe nekutadza kutakura, kukotama kweshaft inotenderera, nzvimbo dzakasiyana dzeaxial dzevhavha yekupedzisira, base yemuchina uye rotor. , yakasununguka fasteners kana kusaenzana injini yekuisa nheyo, uye kuiswa hakusi munzvimbo.Inogonawo kukonzerwa nekuguma kwemagetsi, iyo inofanira kubviswa maererano nemamiriro ezvinhu chaiwo.
3. Kubata hakushandi zvakanaka, izvo zvichanyatsoita kuti motokari inopisa
Kana kubereka kunoshanda nguva dzose kunogona kutongwa nekunzwa uye ruzivo rwekushisa.Shandisa ruoko kana thermometer kuona painoperera kuti uone kana tembiricha yaro iri mukati menguva yakajairika;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 kutsiviwa negirisi maawa matatu kusvika zviuru zvishanu ega ega ekushanda.
4. Iyo magetsi emagetsi akawandisa, iyo yekukurudzira ikozvino inowedzera, uye mota ichapisa
Yakawandisa voltages inogona kukanganisa iyo motor insulation, ichiisa panjodzi yekuparara.Kana magetsi emagetsi akanyanya kuderera, iyo electromagnetic torque inoderedzwa.Kana iyo torque yemutoro isina kuderedzwa uye kumhanya kwerotor kwakadzikira, kuwedzera kweiyo slip ratio kuchaita kuti mota iwedzere uye kupisa, uye kuremerwa kwenguva refu kuchakanganisa hupenyu hwemota.Kana iyo matatu-phase voltage iri asymmetric, ndiko kuti, kana voltage yechimwe chikamu yakakwira kana yakaderera, ikozvino yeimwe chikamu ichave yakakura kwazvo, mota ichapisa, uye panguva imwe chete, torque ichave. kuderedzwa, uye ruzha rwe "humming" ruchabudiswa, izvo zvichakuvadza kumonereka kwenguva refu.
Muchidimbu, hazvina mhosva kuti voltage yakawandisa, yakaderera kana kuti voltage is asymmetrical, ikozvino ichawedzera, uye mota ichapisa nekukuvadza mota.Naizvozvo, zvinoenderana nechiyero chenyika, shanduko yemagetsi emagetsi emagetsi haifanire kudarika ± 5% yehuwandu hwakayerwa, uye iyo mota inobuda simba inogona kuchengetedza yakayerwa kukosha.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 mekunge kuvharirwa pakati pewaya mbiri dziri padyo mumhepo kunenge kwakuvadzwa, makondukita maviri anodhumhana, anonzi mapfupi emhepo.Dunhu diki rinomonereka rinoitika mumhepo yakafanana inonzi turn-to-turn short circuit.Dunhu diki rinomonereka rinoitika pakati pezvikamu zviviri zvinomonereka rinonzi interphase short circuit.Hazvina mhosva kuti ndeipi, ichawedzera ikozvino yechikamu chimwe kana nhanho mbiri, kukonzera kupisa kwenzvimbo, uye kukuvadza mota nekuda kwekuchembera kwekudzivirira.Winding open circuit zvinoreva kukanganisa kunokonzerwa nekutsemuka kana kupisa kwe stator kana rotor winding of motor.Kunyangwe mhepo ipfupi-yakatenderedzwa kana yakavhurika-yakatenderedzwa, inogona kukonzera mota kupisa kana kupisa.Nokudaro, inofanira kumiswa pakarepo mushure mokunge izvi zvaitika.
6. Izvo zvinhu zvinopinda mukati memotor, izvo zvinoderedza kusungirirwa kwemota, nekudaro kuderedza kukwira kunobvumidzwa kwekushisa kwemota.
Zvishandiso zvakasimba kana guruva rinopinda mumotor kubva mubhokisi rekusangana rinosvika pakagero remhepo pakati pe stator uye rotor yemota, zvichiita kuti mota itsvairwe, kudzamara kuvharirwa kwemotor winding kwapera, zvichiita kuti mota ikuvadzwe kana kuraswa. .Kana iyo yemvura uye gasi yepakati ikanyudza mumotor, inokonzeresa zvakananga kuti mota insulation idonhe uye kufamba.
General liquid uye gasi kuvuza kune zvinotevera zviratidzo:
(1) Kudonhedza kwemidziyo yakasiyana-siyana uye mapaipi ekufambisa, kuvuza kwepombi yemuviri zvisimbiso, midziyo yekutsvaira uye pasi, nezvimwe.
(2) Mushure mekunge mafuta emuchina adonha, anopinda mumotokari kubva pakakoromoka rebhokisi rekumberi.
(3) Zvisimbiso zveoiri senge chinodzikisira chakabatana nemota zvinopfekwa, uye oiri yekuzora yemuchina inopinda ichitevedza mota shaft.Mushure mekuunganidza mukati memotor, iyo mota insulating pendi inonyungudika, kuitira kuti iyo insulation performance yemota inoderedzwa zvishoma nezvishoma.
7. Inenge hafu yemoto inopisa inokonzerwa nekushayikwa kwechikamu chekushanda kwemotokari
Kushaikwa kwechikamu kunowanzoita kuti mota ikundikane kumhanya, kana kutenderera zvishoma nezvishoma mushure mekutanga, kana kuburitsa ruzha rwe "humming" kana simba risiri kutenderera uye ikozvino inowedzera.Kana mutoro uri pa shaft usingashanduki, motokari inoremerwa zvakanyanya uye stator ikozvino ichava 2 nguva iyo yakarongwa kukosha kana kunyange yakakwirira.Munguva pfupi, injini ichapisa kana kutopisa.kukonzera kurasikirwa kwechikamu.
Zvikonzero zvikuru ndezvizvi:
(1) Kutadza kwesimba kwechikamu chimwe kunokonzerwa nezvimwe kutadza kushanda patambo yemagetsi kuchaita kuti mamwe matatu-chikamu midziyo yakabatana netambo ishande isina chikamu.
(2) Imwe nhanho yedunhu rinotyora kana contactor yabuda muchikamu nekuda kwekutsva kwe bias voltage kana kusabatana zvakanaka.
(3) Kurasikirwa kwechikamu nekuda kwekuchembera, kupfeka, nezvimwe zvemutsetse unouya wemota.
(4) Iyo imwe-chikamu mhepo inotenderera yemota yakavhurika dunhu, kana imwe-chikamu chekubatanidza mubhokisi rejunction yakasununguka.
8. Zvimwe zvisiri zvemagetsi kukundikana kwemagetsi zvinokonzera
Kukwira kwekushisa kwemota kunokonzerwa nedzimwe dzisiri dzemagetsi kutadza kwemagetsi zvinogonawo kutungamira mukutadza kwemota mumatambudziko akaomarara.Kana tembiricha ye ambient yakakwira, mota inoshaya fan, fan haina kukwana, kana chivharo che fan chisipo.Muchiitiko ichi, kutonhora kwekumanikidzwa kunofanirwa kuve nechokwadi kuti ive nechokwadi chekufefetedza kana kutsiva mablades fan, 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, isu tinogona kudzivirira kutsauka, kuchengetedza nguva, kugadzirisa dambudziko nekukurumidza sezvinobvira, uye chengetedza mota iri mune yakajairika inoshanda mamiriro.Kuti uve nechokwadi chekugadzirwa kwakajairika kwemusangano.
