Feem ntau ua rau Stator Failure
Kev puas tsuaj ntawm stator feem ntau tshwm sim los ntawm cov teeb meem hluav taws xob, khoom siv, lossis ib puag ncig, feem ntau ua rau muaj kev saib xyuas tsis zoo lossis siv tsis raug. Feem ntau cov laj thawj tau piav qhia hauv qab no, nrog rau kev nkag siab txog lawv cov teebmeem thiab cov xwm txheej tshwm sim.
Hluav taws xob overload los yog Voltage fluctuations
Cov teeb meem hluav taws xob yog qhov ua rau ntawm stator tsis ua haujlwm, vim tias cov stator windings muaj qhov cuam tshuam rau qhov voltage thiab tam sim no irregularities. Thaum lub cev muaj zog raug hluav taws xob ntau dhau -xws li lub hwj chim ntawm qhov hnyav dua li nws qhov peev xwm ntsuas - lossis tam sim no qhov hloov pauv voltage (spikes lossis dips), lub stator windings nqa ntau dhau tam sim no. Qhov no overload ua rau lub windings overheat sai, ua rau cov insulating txheej nyob ib ncig ntawm cov tooj liab los yog txhuas coils. Thaum lub sij hawm, cov rwb thaiv tsev tawg, ua rau luv luv Circuit Court ntawm windings (inter-tig luv circuits) los yog ntawm windings thiab stator core (hauv av faults), ob qho tib si ua rau lub stator inoperable.
Cov xwm txheej feem ntau suav nrog kev siv lub cev muaj zog tshaj nws lub zog ntsuas, lub zog tsis ruaj khov los ntawm daim phiaj, lossis kev xaim hluav taws xob tsis zoo uas ua rau muaj qhov tsis txaus ntseeg tam sim no. Voltage spikes, feem ntau tshwm sim los ntawm xob laim lossis hluav taws xob surges, tuaj yeem hlawv tawm ntawm stator windings tam sim ntawd.
Overheating (Thermal puas)
Lub tuam txhab yog 'Tus Tswv Cuab ntawm Tuam Tshoj Sab Hauv Tsev Kho Kom Zoo Nkauj', 'National Excellent Enterprise in Air Interior Decoration', thiab tau ntaus nqi raws li 'Top Ten Brands of Electric Curtains', nrog 7 cov khoom lag luam patents, thiab nws yog qhov zoo -paub hauv kev lag luam.
Rwb thaiv tsev Deterioration
Lub stator windings yog coated nrog ib tug insulating khoom (xws li, enamel, epoxy resin) los tiv thaiv luv luv circuits. Nyob rau tib lub sijhawm, qhov rwb thaiv tsev no degrades vim muaj hnub nyoog, cua sov, lossis tshuaj lom neeg, ua rau stator tsis ua haujlwm. Cov yam tseem ceeb ua kom cov rwb thaiv tsev deterioration muaj xws li:
• Kev laus: Ntau xyoo ntawm kev siv, cov khoom siv rwb thaiv tsev ua nkig, tawg, lossis tev tawm, nthuav tawm cov coils liab qab rau luv luv.
• Tshuaj lom neeg: Raug rau cov roj, cov kuab tshuaj, los yog cov roj corrosive (xws li, nyob rau hauv industrial lossis marine ib puag ncig) rhuav tshem cov rwb thaiv tsev, ua rau nws cov khoom tiv thaiv tsis muaj zog.
• Moisture ingress: Cov dej los yog cov av noo nkag mus rau hauv lub cev muaj zog, ua rau cov rwb thaiv tsev puas tsuaj thiab ua rau hauv av txhaum ntawm cov windings thiab cov tub ntxhais stator. Qhov no tshwm sim nyob rau sab nraum zoovlub cev muaj zog lossis cov uas siv nyob rau hauv siab - cov av noo (piv txwv li, twj tso kua mis, qhov chaw ntxuav).
Mechanical puas
Kev ntxhov siab lossis kev cuam tshuam ntawm lub cev tuaj yeem ua rau lub stator ncaj qha, tshwj xeeb tshaj yog nws cov tub ntxhais thiab windings. Common mechanical ua rau muaj xws li:
•Rotor rub: Raws li tau hais ua ntej lawm, faulty bearings lossis misalignment ntawm lub rotor thiab stator ua rau lub rotor rub tawm ntawm stator core. Qhov kev sib txhuam no rub lub hauv paus, ua rau cov windings puas, thiab ua kom sov, ua rau tsis ua haujlwm sai.
• Kev cuam tshuam lub cev: Kev tso lub cev muaj zog, kev teeb tsa tsis raug, lossis cov khoom khib nyiab (xws li, hlau shavings, plua plav) nkag mus rau lub cev muaj zog tuaj yeem cuam tshuam cov tub ntxhais stator, tawg winding coils, lossis cov khoom tawg.
• Kev vibration: Kev co ntau dhau los ntawm lub cev muaj zog lossis cov khoom siv nyob ib puag ncig tuaj yeem txo cov stator windings, ua rau lawv sib tsoo los yog cov tub ntxhais, ua rau cov rwb thaiv tsev puas thiab ua rau luv luv Circuit Court.
Contamination thiab Debris
Plua plav, av, hlau shavings, los yog lwm yam khib nyiab tuaj yeem sib sau ua ke hauv lub cev muaj zog, ua rau muaj kev puas tsuaj rau stator. Cov khoom zoo tuaj yeem daig ntawm cov stator windings, ua rau rwb thaiv tsev hnav lossis luv luv Circuit Court. Cov khib nyiab hlau, tshwj xeeb, tuaj yeem ua hluav taws xob, tsim kom muaj luv luv ntawm windings. Kev kis kab mob kuj thaiv qhov cua, ua rau muaj cua sov ntau dhau - ua rau lub voj voog ntawm kev puas tsuaj uas ua rau cov stator tsis ua haujlwm. Qhov no yog ib txwm muaj nyob rau hauv kev lag luam chaw uas cov motors raug rau cov pa phem.
Yuav tiv thaiv Stator Failure li cas
Thaum kev puas tsuaj ntawm stator tuaj yeem tshwm sim vim muaj ntau yam, kev saib xyuas thiab kev siv kom zoo tuaj yeem txo qhov kev pheej hmoo:
• Tsis txhob muaj hluav taws xob ntau dhau: Xyuas kom lub cev muaj zog siv nyob rau hauv nws cov nqi zog thiab qhov hluav taws xob ntau; siv surge protectors los tiv thaiv voltage spikes.
• Khaws qhov cua kom zoo: Tsis tu ncua ntxuav cov cua vents, cua txias kiv cua, thiab lub cev muaj zog sab nrauv kom ntseeg tau tias muaj cua sov dissipation txaus.
• Tshawb xyuas cov rwb thaiv tsev tsis tu ncua: Tshawb xyuas cov cim qhia txog kev puas tsuaj ntawm cov rwb thaiv tsev (xws li, kev hloov xim, tsw ntxhiab tsw) thiab hloov cov hlua khi tam sim ntawd.
• Tiv thaiv kom tsis txhob ya raws thiab kis kab mob: Khaws cov motors hauv qhov chaw qhuav, huv si; siv cov ntaub thaiv npog rau sab nraum zoov lossis siab - cov av noo.
• Txheeb xyuas cov kabmob thiab kev sib dhos: Tsis tu ncua lubricate bearings thiab xyuas kom lub rotor raug raws li txoj cai kom tsis txhob rub tawm ntawm stator.
Nyob rau hauv cov ntsiab lus, stator tsis ua hauj lwm feem ntau yog tshwm sim los ntawm hluav taws xob overload, overheating, rwb thaiv tsev deterioration, mechanical puas, los yog paug. Los ntawm kev nkag siab txog cov laj thawj no thiab ua raws li kev saib xyuas kom raug, koj tuaj yeem txuas ntxiv lub neej ntawm stator, txo lub sijhawm lub cev muaj zog, thiab ua kom ntseeg tau tias lub cev muaj zog.
