Iyo inowanzo shandiswa yekuona michina yemagetsi motors inosanganisira: stator tembiricha yekuyera mudziyo, inotakura tembiricha yekuyera mudziyo, mvura inodonha yekuona mudziyo, stator winding grounding differential dziviriro, nezvimwe.Mamwe mahombe mota akashongedzerwa shaft vibration yekuona probes, asi nekuda kwekushomeka kwakaderera uye mutengo wakakwira, sarudzo idiki.
• Maererano ne stator winding tembiricha monitoring uye over-temperature kudzivirira: mamwe low-voltage motors anoshandisa PTC thermistors, uye tembiricha yekudzivirira i135 ° C kana 145 ° C.Iyo stator mhepo yeakakwira-voltage mota yakamisikidzwa ne6 Pt100 platinum thermal resistors (matatu-waya system), 2 pachikamu, 3 kushanda uye 3 yakamira.
• Panyaya yekutakura kutarisa kwekushisa uye kuchengetedzwa kwepamusoro-kupisa: imwe neimwe kutakura kwemotokari inopiwa nePt100 kaviri platinum thermal resistance (matatu-waya system), inokwana 2, uye mamwe mamota anongoda chete pane-saiti tembiricha kuratidza.Tembiricha yemota inotakura goko haifanire kudarika 80°C, tembiricha yealarm i80°C, uye tembiricha yekudzima i85°C.Iyo injini inotakura tembiricha haifanirwe kudarika 95 ° C.
• Injini inopihwa matanho ekudzivirira kudonha kwemvura: kune mota yakanyoroveswa nemvura ine kutonhora kwemvura yepamusoro, switch yekuona kubuda kwemvura inowanzoiswa. Kana iyo inotonhorera inodonhedza kana imwe huwandu hwekuvuza ikaitika, iyo control system inoburitsa alarm.
• Grounding differential dziviriro ye stator windings: Zvinoenderana neakakodzera nyika zviyero, kana iyo mota simba rakakura kupfuura 2000KW, iyo stator windings inofanira kunge yakashongedzerwa negrounding differential protection devices.
Zvigadzirwa zvemotor zvinoiswa sei?
Motor stator
Iyo mota stator chikamu chakakosha chemotor senge jenareta uye kutanga.Iyo stator chikamu chakakosha chemota.Iyo stator ine zvikamu zvitatu: stator core, stator winding uye furemu.Basa guru re stator nderekugadzira magineti inotenderera, uye basa guru re rotor rinofanira kutemwa nemagineti mitsara yesimba mune inotenderera magnetic field kuti ibudise (output) ikozvino.
mota rotor
Iyo mota rotor zvakare chikamu chinotenderera mumotokari.Motokari ine zvikamu zviviri, rotor uye stator. Inoshandiswa kuona mudziyo wekushandura pakati pesimba remagetsi nemagetsi emagetsi uye simba remagetsi uye simba remagetsi.Iyo mota rotor yakakamurwa kuita mota rotor uye jenareta rotor.
stator winding
Iyo stator winding inogona kukamurwa kuita mhando mbiri: pakati uye kugoverwa zvinoenderana nechimiro checoil mhepo uye nzira yekumisikidzwa wiring.Iko kupeta uye kuisirwa kwepakati pemhepo inotenderera iri nyore, asi kunyatsoita kwakadzikira uye kuita kwekuita kwakashata zvakare.Parizvino, mazhinji emastators e AC motors anoshandisa akagoverwa windings. Zvinoenderana neakasiyana mamodheru, mamodheru uye maitiro ekugadzirisa coil mhepo, iwo mota dzakagadzirwa nemhando dzakasiyana dzemhepo uye zvirevo, saka tekinoroji maparamendi emhepo inotenderera zvakare akasiyana.
mota dzimba
Iyo mota casing kazhinji inoreva kune yekunze casing yezvese magetsi nemagetsi zvishandiso.Iyo mota casing mudziyo wekudzivirira wemota, iyo inogadzirwa nesilicon simbi pepa uye zvimwe zvinhu nekutsikisa uye kudhirowa kwakadzika maitiro.Uye zvakare, iyo yepamusoro anti-ngura uye kupfapfaidza uye mamwe maitiro ekurapa anogona kunyatso chengetedza mukati memidziyo yemota.Mabasa makuru: guruva, anti-ruzha, kusapinda kwemvura.
end cap
Chivharo chekupedzisira chivharo chekumashure chakaiswa kuseri kwekasi yemota, inowanzozivikanwa se "yekupedzisira chivharo", iyo inonyanya kuumbwa nemuviri wekuvhara, inotakura, uye bhurasho remagetsi.Kunyangwe chivharo chekupedzisira chakanaka kana chakaipa chinokanganisa zvakananga kunaka kwemotokari.Chifukidziro chakanaka chekupedzisira chinonyanya kubva pamwoyo wayo - bhurashi, basa rayo nderokufambisa kutenderera kwe rotor, uye chikamu ichi ndicho chikamu chinokosha.
Motor fan blades
Iwo fan blades emota anowanzo kuwanikwa pamuswe wemota uye anoshandiswa kufefetera uye kutonhora kwemota. Iwo anonyanya kushandiswa pamuswe weiyo AC mota, kana anoiswa mune yakakosha kufefetera maducts eDC uye akakwira-voltage motors.Iwo ma fan blades emamotor-ekudzivirira-kuputika anowanzo kugadzirwa epurasitiki.
Zvinoenderana nemhando yezvinyorwa: mota fan blades inogona kukamurwa kuita mhando nhatu, uye epurasitiki fan blades, akakanda aluminium fan blades, akakanda simbi fan blades.
kubereka
Bearings chinhu chakakosha mumichina yemazuva ano nemidziyo.Basa rayo guru ndere kutsigira mechanical inotenderera muviri, kuderedza friction coefficient panguva yekufamba kwayo, uye kuve nechokwadi chekutenderera kwayo.
Rolling bearings anowanzo kuumbwa nezvikamu zvina: mhete yekunze, mhete yemukati, muviri unokunguruka uye keji. Kunyatsotaura, inoumbwa nezvikamu zvitanhatu: mhete yekunze, mhete yemukati, muviri unotenderedza, keji, chisimbiso uye mafuta ekuzora.Kunyanya nemhete yekunze, mhete yemukati uye inotenderedza zvinhu, inogona kutsanangurwa sekutenderera inobereka.Zvichienderana nechimiro chezvimisikidzwa, mabheji ekutenderera akakamurwa kuita mapoka maviri: bhora bhora uye roller bearings.
