Cov cuab yeej siv ntau tshaj plaws rau cov tshuab hluav taws xob muaj xws li: stator ntsuas kub ntsuas, ntsuas ntsuas ntsuas ntsuas, ntsuas dej ntws tawm, stator winding grounding sib txawv tiv thaiv, thiab lwm yam.Qee lub cev muaj zog loj tau nruab nrog cov ncej vibration detection probes, tab sis vim yog qhov tsim nyog tsawg thiab tus nqi siab, kev xaiv me me.
• Hais txog kev ntsuas kub ntawm stator winding thiab tiv thaiv kub dhau: qee lub tshuab hluav taws xob qis siv PTC thermistor, thiab kev tiv thaiv kub yog 135 ° C lossis 145 ° C.Lub stator winding ntawm high-voltage motor yog embedded nrog 6 Pt100 platinum thermal resistors (peb-xaim system), 2 ib theem, 3 ua hauj lwm thiab 3 standby.
• Hais txog kev ntsuas kub thiab kev tiv thaiv kub dhau: txhua lub cev muaj zog yog muab nrog Pt100 ob chav platinum thermal tsis kam (peb-xaim system), tag nrho ntawm 2, thiab qee lub motors tsuas yog xav tau qhov ntsuas kub ntawm qhov chaw.Qhov kub ntawm lub cev muaj zog bearing plhaub yuav tsum tsis pub tshaj 80 ° C, lub tswb ntsuas kub yog 80 ° C, thiab kaw qhov kub yog 85 ° C.Lub cev muaj zog bearing kub yuav tsum tsis pub tshaj 95 ° C.
• Lub cev muaj zog yog muab kev tiv thaiv kev tiv thaiv dej: rau cov dej txias lub cev muaj zog nrog cov dej txias sab saud, feem ntau ntsia cov dej ntws tawm mus. Thaum lub qhov txias txias los yog ib qho ntawm cov dej xau tshwm sim, lub kaw lus tswj yuav teeb lub tswb.
• Kev tiv thaiv kev sib txawv ntawm cov stator windings: Raws li cov qauv hauv lub tebchaws, thaum lub zog lub cev muaj zog ntau dua 2000KW, cov stator windings yuav tsum tau nruab nrog cov khoom siv tiv thaiv grounding sib txawv.
Cov khoom siv lub cev muaj zog li cas?
Lub cev muaj zog stator
Lub cev muaj zog stator yog ib qho tseem ceeb ntawm cov motors xws li generators thiab starters.Lub stator yog ib qho tseem ceeb ntawm lub cev muaj zog.Lub stator muaj peb ntu: stator core, stator winding thiab ncej.Lub luag haujlwm tseem ceeb ntawm lub stator yog tsim kom muaj qhov sib nqus sib nqus, thiab lub luag haujlwm tseem ceeb ntawm lub rotor yog txiav los ntawm cov kab sib nqus ntawm lub zog hauv lub rotating magnetic teb los tsim (tso tawm) tam sim no.
lub cev muaj zog rotor
Lub rotor lub cev muaj zog kuj yog ib feem ntawm lub cev muaj zog.Lub cev muaj zog muaj ob ntu, rotor thiab stator. Nws yog siv los paub txog cov cuab yeej hloov pauv ntawm lub zog hluav taws xob thiab cov khoom siv hluav taws xob thiab cov khoom siv hluav taws xob thiab hluav taws xob hluav taws xob.Lub cev muaj zog rotor tau muab faib ua lub cev muaj zog rotor thiab lub tshuab hluav taws xob rotor.
stator winding
Lub stator winding tuaj yeem muab faib ua ob hom: centralized thiab faib raws li cov duab ntawm cov coil winding thiab txoj hauv kev ntawm cov hlua khi.Lub winding thiab embedding ntawm centralized winding yog ib qho yooj yim, tab sis cov efficiency yog tsawg thiab kev khiav hauj lwm kuj tsis zoo.Tam sim no, feem ntau ntawm cov stators ntawm AC motors siv cov kab sib faib. Raws li cov qauv sib txawv, cov qauv thiab cov txheej txheem ntawm coil winding, cov motors yog tsim los nrog ntau hom winding thiab specifications, yog li cov kev tsis sib xws ntawm windings kuj txawv.
lub cev muaj zog
Lub cev lub cev feem ntau yog hais txog sab nraud ntawm txhua yam khoom siv hluav taws xob thiab hluav taws xob.Lub cev muaj zog casing yog cov cuab yeej tiv thaiv ntawm lub cev muaj zog, uas yog ua los ntawm silicon steel ntawv thiab lwm yam ntaub ntawv los ntawm stamping thiab sib sib zog nqus nqus txheej txheem.Tsis tas li ntawd, qhov chaw tiv thaiv xeb thiab txau thiab lwm cov txheej txheem kev kho mob tuaj yeem tiv thaiv cov khoom siv sab hauv ntawm lub cev muaj zog.Lub luag haujlwm tseem ceeb: tsis muaj plua plav, tiv thaiv suab nrov, tsis muaj dej.
kawg cap
Lub hau kawg yog lub hau rov qab ntsia tom qab lub casing ntawm lub cev muaj zog, feem ntau hu ua "qhov kawg npog", uas yog tsim los ntawm lub cev npog, cov kabmob, thiab txhuam hluav taws xob.Txawm hais tias qhov kawg npog yog qhov zoo lossis qhov phem ncaj qha cuam tshuam rau qhov zoo ntawm lub cev muaj zog.Qhov zoo kawg npog feem ntau yog los ntawm nws lub siab - txhuam, nws txoj haujlwm yog tsav kev sib hloov ntawm lub rotor, thiab qhov no yog qhov tseem ceeb.
Lub cev muaj zog kiv cua
Cov kiv cua ntawm lub cev muaj zog feem ntau yog nyob ntawm tus Tsov tus tw ntawm lub cev muaj zog thiab yog siv rau qhov cua thiab cua txias ntawm lub cev muaj zog. Lawv feem ntau yog siv rau ntawm tus Tsov tus tw ntawm AC lub cev muaj zog, los yog muab tso rau hauv qhov tshwj xeeb qhov cua ducts ntawm DC thiab high-voltage motors.Cov kiv cua ntawm cov khoom tawg-pov thawj motors feem ntau yog ua los ntawm cov yas.
Raws li cov khoom faib: lub tshuab kiv cua tuaj yeem muab faib ua peb hom, thiab cov kiv cua yas, cam khwb cia txhuas kiv cua, cam khwb cia hlau ntxuam hniav.
bearing
Bearings yog ib qho tseem ceeb ntawm cov tshuab thiab khoom siv niaj hnub no.Nws lub luag haujlwm tseem ceeb yog txhawm rau txhawb nqa lub tshuab tig lub cev, txo cov kev sib txhuam coefficient thaum nws txav mus los, thiab xyuas kom meej nws cov kev sib hloov raug.
Rolling bearings feem ntau yog tsim los ntawm plaub ntu: lub nplhaib sab nraud, lub nplhaib puab, dov lub cev thiab lub tawb. Hais lus nruj me ntsis, nws yog tsim los ntawm rau qhov chaw: lub nplhaib sab nraud, lub nplhaib puab, dov lub cev, tawb, foob thiab lubricating roj.Feem ntau nrog lub nplhaib sab nraud, lub nplhaib puab thiab cov khoom dov, nws tuaj yeem txhais tau tias yog dov bearing.Raws li cov duab ntawm cov khoom dov, dov bearings tau muab faib ua ob pawg: pob bearings thiab cov menyuam bearings.
