Izixhobo ezisetyenziswa ngokuqhelekileyo zokufumanisa iinjini zombane ziquka: isixhobo sokulinganisa ubushushu be-stator, isixhobo sokulinganisa ubushushu, isixhobo sokubona ukuvuza kwamanzi, i-stator winding grounding grounding differential protection, njl.Ezinye iinjini ezinkulu zixhotyiswe nge-shaft vibration probes zokubona, kodwa ngenxa yemfuno ephantsi kunye neendleko eziphezulu, ukhetho luncinci.
• Ngokubhekiselele kwi-stator winding monitoring yeqondo lobushushu kunye nokukhuselwa kobushushu obugqithisileyo: ezinye iimotor ezine-voltage ephantsi zisebenzisa i-PTC thermistors, kwaye ubushushu bokhuselo yi-135°C okanye i-145°C.I-stator winding ye-high-voltage motor ifakwe kunye ne-6 Pt100 i-platinum resistors ye-thermal (inkqubo ye-wire-three), i-2 ngesigaba ngasinye, i-3 yokusebenza kunye ne-3 yokulinda.
• Ngokubhekiselele kwi-bearing monitoring monitoring and over-temperature protection: nganye yokuthwala i-motor ibonelelwa nge-Pt100 i-platinum double thermal resistance (inkqubo ye-wire-three), i-2 iyonke, kunye nezinye ii-motor zifuna kuphela umboniso wokushisa kwisayithi.Ubushushu beqokobhe elithwala i-motor akufanele lidlule kwi-80 ° C, iqondo lokushisa yi-80 ° C, kwaye ubushushu bokucima ngu-85 ° C.Iqondo lobushushu lemoto akufunekanga libe ngaphezu kwama-95°C.
• Injini ibonelelwa ngamanyathelo okuthintela ukuvuza kwamanzi: kwimoto epholiswe ngamanzi enokupholiswa kwamanzi aphezulu, iswitshi yokufumanisa ukuvuza kwamanzi ifakelwe ngokubanzi.Xa ukuvuza okupholileyo okanye umlinganiselo othile wokuvuza kwenzeka, inkqubo yokulawula iya kukhupha i-alam.
• Ukukhuselwa kokwahluka komgangatho we-stator windings: Ngokwemigangatho yelizwe efanelekileyo, xa amandla emoto engaphezulu kwe-2000KW, i-stator windings kufuneka ixhotyiswe ngezixhobo zokukhusela ezisezantsi.
Zihlelwa njani izincedisi zeemoto?
Istator yemoto
I-motor stator yinxalenye ebalulekileyo yeenjini ezifana neejeneretha kunye nabaqalayo.I-stator yinxalenye ebalulekileyo yemoto.I-stator iqulethwe ngamacandelo amathathu: i-stator core, i-stator winding kunye nesakhelo.Umsebenzi oyintloko we-stator kukuvelisa intsimi yamagnetic ejikelezayo, kwaye umsebenzi oyintloko we-rotor kufuneka unqunywe yimigca yamagnetic yamandla kwindawo ejikelezayo yamagnetic ukuvelisa (imveliso) yangoku.
i-motor rotor
I-motor rotor ikwayinxalenye ejikelezayo kwi-motor.I-motor iqukethe iinxalenye ezimbini, i-rotor kunye ne-stator.Isetyenziselwa ukuqonda isixhobo sokuguqula phakathi kwamandla ombane kunye namandla oomatshini kunye namandla oomatshini kunye namandla ombane.I-motor rotor ihlukaniswe kwi-motor rotor kunye ne-rotor generator.
ukujika kwestator
I-stator winding inokwahlulwa ibe ziindidi ezimbini: i-centralized kwaye isasazwe ngokwemilo ye-coil winding kunye nendlela ye-wiring edibeneyo.Ukujija kunye nokufakela i-wingized winding kulula, kodwa ukusebenza kakuhle kuphantsi kwaye ukusebenza okusebenzayo kukwabi.Okwangoku, uninzi lwe-stators yeenjini ze-AC zisebenzisa i-windings esasazwayo.Ngokweemodeli ezahlukeneyo, iimodeli kunye neemeko zenkqubo ye-coil windings, ii-motor zenzelwe iintlobo ezahlukeneyo zomoya kunye neenkcukacha, ngoko ke iiparitha zobugcisa ze-windings nazo zihluke.
izindlu zeemoto
I-motor casing ngokubanzi ibhekisa kwi-casing yangaphandle yazo zonke izixhobo zombane nezombane.I-motor casing sisixhobo sokukhusela se-motor, esenziwe nge-silicon sheet sheet kunye nezinye izinto ngokugxilwa kunye nenkqubo enzulu yokuzoba.Ukongeza, umphezulu wokuchasa umhlwa kunye nokutshiza kunye nolunye unyango lwenkqubo inokukhusela kakuhle izixhobo zangaphakathi zemoto.Imisebenzi ephambili: uthuli, anti-ingxolo, ungangeni manzi.
isiphelo cap
Isigqubuthelo sokugqibela sisigqubuthelo sangasemva esifakwe ngasemva kwecasing yemoto, eyaziwa ngokuba “sisigqubuthelo sokugqibela”, esakhiwe ikakhulu ngumzimba wokugquma, i-bearing, kunye nebrashi yombane.Nokuba isiciko sokugqibela silungile okanye sibi sichaphazela ngokuthe ngqo umgangatho wenjini.Isigqubuthelo esilungileyo sokugqibela siphuma entliziyweni - i-brush, umsebenzi wayo kukuqhuba ukujikeleza kwe-rotor, kwaye le nxalenye inxalenye ephambili.
Iintsimbi zefeni yemoto
Iiblayidi zefeni yemoto zihlala zibekwe emsileni wenjini kwaye zisetyenziselwa ukungena komoya kunye nokupholisa imotor.Zisetyenziswa ikakhulu kumsila we-AC motor, okanye zibekwe kwiindlela ezikhethekileyo zokungenisa umoya ze-DC kunye ne-high-voltage motors.Ii-fan blades zee-motor-proof-proof ngokuvamile zenziwe ngeplastiki.
Ngokwahlulahlulo lwemathiriyeli: iiblayidi zefeni yemoto zinokwahlulwa zibe ziindidi ezintathu, kunye neeblayizi zeplastiki zefestile, iiblayisi ze-aluminium eziphosekileyo, iintsimbi zentsimbi.
ukuzala
Iibheringi ziyinxalenye ebalulekileyo koomatshini kunye nezixhobo zangoku.Umsebenzi wayo oyintloko kukuxhasa umzimba ojikelezayo womatshini, ukunciphisa i-coefficient ye-friction ngexesha lokuhamba kwayo, kunye nokuqinisekisa ukuchaneka kwayo kokujikeleza.
Iibheringi eziqengqelekayo ngokuqhelekileyo zenziwe ngamacandelo amane: iringi yangaphandle, iringi yangaphakathi, umzimba oqengqelekayo kunye nekheji.Ukuthetha ngokuthe ngqo, yenziwe ngamacandelo amathandathu: umsesane wangaphandle, umsesane wangaphakathi, umzimba oqengqelekayo, ikheji, itywina kunye neoyile yokuthambisa.Ngokukodwa ngendandatho yangaphandle, i-ring yangaphakathi kunye nezinto eziqengqelekayo, inokuchazwa njengokuthwala.Ngokwemilo yezinto ezijikelezayo, iibheringi ezijikelezayo zihlulwe zibe ngamacandelo amabini: iibhola zebhola kunye ne-roller bearings.
