Kusankha zida zoyezera magalimoto ndi zowonjezera

Chiyambi:Zida zodziwira zomwe zimagwiritsidwa ntchito kwambiri pama motors ndi: chipangizo choyezera kutentha kwa stator, chipangizo choyezera kutentha, chipangizo chodziwira kuti madzi akutuluka, chitetezo cha stator winding grounding, etc.Ma motors ena akuluakulu ali ndi ma probes ozindikira ma shaft vibration, koma chifukwa cha kufunikira kotsika komanso kukwera mtengo, kusankhako kumakhala kochepa.

Zida zodziwira zomwe zimagwiritsidwa ntchito kwambiri pama motors amagetsi ndi izi: chipangizo choyezera kutentha kwa stator, chipangizo choyezera kutentha, chipangizo chodziwira kuti madzi akutuluka, chitetezo cha stator winding grounding, etc.Ma motors ena akuluakulu ali ndi ma probes ozindikira ma shaft vibration, koma chifukwa cha kufunikira kotsika komanso kukwera mtengo, kusankhako kumakhala kochepa.

• Pankhani ya kuyang'anira kutentha kwa stator ndi kuteteza kutentha kwambiri: ma motors ena otsika kwambiri amagwiritsa ntchito PTC thermistors, ndipo kutentha kwa chitetezo ndi 135 ° C kapena 145 ° C.Mapiritsi a stator a motor-voltage motor amaphatikizidwa ndi 6 Pt100 platinamu matenthedwe resistors (waya atatu dongosolo), 2 pa gawo, 3 ntchito ndi 3 standby.

• Ponena za kunyamula kuyang'anira kutentha ndi chitetezo cha kutentha kwambiri: kunyamula kulikonse kwa galimoto kumaperekedwa ndi Pt100 double platinamu kukana kutentha (machitidwe atatu a waya), chiwerengero cha 2, ndi injini zina zimangofunika kuwonetsera kutentha kwa malo.Kutentha kwa chipolopolo chonyamula galimoto sikuyenera kupitirira 80 ° C, kutentha kwa alamu ndi 80 ° C, ndipo kutentha kwa shutdown ndi 85 ° C.Kutentha kwa injini sikuyenera kupitirira 95 ° C.

• Galimoto imapatsidwa njira zopewera kuti madzi asatayike: pagalimoto yoziziritsa madzi yokhala ndi kuziziritsa kwamadzi kumtunda, chosinthira chozindikira kuti madzi akutuluka nthawi zambiri chimayikidwa. Kutayikira koziziritsa kutayikira kapena kutayikira kwina kwina, makina owongolera amatulutsa alamu.

• Kutetezedwa kosiyana kwa ma stator windings: Malinga ndi mfundo za dziko, mphamvu ya injini ikakhala yoposa 2000KW, ma windings a stator ayenera kukhala ndi zida zotetezera kusiyanitsa.

Gulu la zida zamagalimoto

Kodi zida zamagalimoto zimagawidwa bwanji?

Moto stator

Ma motor stator ndi gawo lofunikira la ma mota monga ma jenereta ndi oyambira.Stator ndi gawo lofunikira la injini.Stator ili ndi magawo atatu: stator core, stator winding ndi frame.Ntchito yaikulu ya stator ndi kupanga mphamvu ya maginito yozungulira, ndipo ntchito yaikulu ya rotor iyenera kudulidwa ndi mizere ya maginito ya mphamvu mu maginito ozungulira kuti apange (zotulutsa) zamakono.

rotor yamoto

The motor rotor ndi gawo lozungulira mu injini.Galimoto ili ndi magawo awiri, rotor ndi stator. Amagwiritsidwa ntchito kuzindikira chipangizo chotembenuka pakati pa mphamvu zamagetsi ndi mphamvu zamakina ndi mphamvu zamakina ndi mphamvu zamagetsi.Rotor yamagalimoto imagawidwa kukhala rotor yama motor ndi rotor ya jenereta.

kukwera kwa stator

Mapiritsi a stator amatha kugawidwa m'mitundu iwiri: yapakati ndikugawidwa molingana ndi mawonekedwe a koyilo yokhotakhota komanso njira yolumikizira ma waya.Kumangirira ndi kuyika kwa mapindikidwe apakati kumakhala kosavuta, koma kuyendetsa bwino kumakhala kochepa komanso kuyendetsa bwino kumakhala kovuta.Pakalipano, ambiri mwa ma stators a AC motors amagwiritsa ntchito ma windings ogawidwa. Malingana ndi mitundu yosiyanasiyana, zitsanzo ndi machitidwe a mapiritsi a coil, ma motors amapangidwa ndi mitundu yosiyanasiyana ya mafunde ndi mafotokozedwe, kotero kuti magawo aukadaulo a ma windings amasiyananso.

nyumba zamoto

Casing yamoto nthawi zambiri imatanthawuza kuyika kwakunja kwa zida zonse zamagetsi ndi zamagetsi.Chophimba chamoto ndi chipangizo chotetezera cha injini, chomwe chimapangidwa ndi chitsulo cha silicon ndi zipangizo zina popondaponda ndi kujambula mozama.Komanso, pamwamba odana ndi dzimbiri ndi kupopera mbewu mankhwalawa ndi njira mankhwala akhoza bwino kuteteza zida mkati galimoto.Ntchito zazikulu: zopanda fumbi, zotsutsana ndi phokoso, zopanda madzi.

kapu yomaliza

Chophimba chakumapeto ndi chivundikiro chakumbuyo chomwe chimayikidwa kumbuyo kwa casing ya galimoto, yomwe imadziwika kuti "chivundikiro chakumapeto", chomwe chimapangidwa makamaka ndi chivundikiro, chotengera, ndi burashi yamagetsi.Kaya chivundikiro chomaliza ndi chabwino kapena choyipa chimakhudza mwachindunji mtundu wagalimoto.Chophimba chabwino chomaliza makamaka chimachokera pamtima - burashi, ntchito yake ndikuyendetsa kuzungulira kwa rotor, ndipo gawo ili ndilo gawo lofunikira.

Mitundu yamagetsi yamagetsi

Ma fan fan nthawi zambiri amakhala kumchira wa mota ndipo amagwiritsidwa ntchito popumira mpweya komanso kuziziritsa injiniyo. Amagwiritsidwa ntchito kwambiri pamchira wa mota ya AC, kapena amayikidwa mumayendedwe apadera a DC ndi ma motor-voltage apamwamba.Ma fan blade a injini zosaphulika nthawi zambiri amapangidwa ndi pulasitiki.

Malinga ndi gulu lazinthu: masamba amakupiza agalimoto amatha kugawidwa m'mitundu itatu, ndi masamba amakupi apulasitiki, masamba opangira aluminium oponyera, ma fan chitsulo.

kubereka

Bearings ndi gawo lofunikira pamakina ndi zida zamakono.Ntchito yake yayikulu ndikuthandizira thupi lozungulira pamakina, kuchepetsa kugunda kwapakati pakuyenda kwake, ndikuwonetsetsa kulondola kwake.

Zopiringa nthawi zambiri zimakhala ndi zigawo zinayi: mphete yakunja, mphete yamkati, thupi logudubuza ndi khola. Kunena zowona, ili ndi magawo asanu ndi limodzi: mphete yakunja, mphete yamkati, thupi lozungulira, khola, chisindikizo ndi mafuta opaka mafuta.Makamaka ndi mphete yakunja, mphete zamkati ndi zinthu zogudubuza, zitha kufotokozedwa ngati kunyamula.Malinga ndi mawonekedwe a zinthu zogubuduza, mayendedwe ogudubuza amagawidwa m'magulu awiri: mayendedwe a mpira ndi ma roller bearings.
