Asynchronous lub cev muaj zog - lub hauv paus ntsiab lus ntawm kev khiav hauj lwm thiab tswj nta
Txheem
Ntawm tag nrho cov hluav taws xob motors, lub asynchronous lub cev muaj zog yuav tsum tau tshwj xeeb tshaj yog sau tseg, lub hauv paus ntsiab lus ntawm kev ua hauj lwm yog raws li nyob rau hauv kev sib cuam tshuam ntawm magnetic teb ntawm stator nrog cov hluav taws xob tam sim no induced los ntawm daim teb no nyob rau hauv lub rotor winding. Lub teb sib nqus rotating yog tsim los ntawm peb-theem alternating tam sim no dhau los ntawm stator winding, uas suav nrog peb pawg coils.
Induction lub cev muaj zog - lub hauv paus ntsiab lus thiab daim ntawv thov
Lub hauv paus ntsiab lus ntawm kev ua haujlwm ntawm lub cev muaj zog asynchronous yog ua raws li qhov ua tau ntawm kev hloov hluav taws xob hluav taws xob rau hauv kev ua haujlwm txhua yam rau txhua lub tshuab thev naus laus zis. Thaum hla lub kaw rotor winding, lub magnetic teb induces ib tug hluav taws xob tam sim no nyob rau hauv nws. Yog li ntawd, lub rotating magnetic teb ntawm lub stator interacts nrog cov tam sim no ntawm lub rotor thiab ua rau cov tshwm sim ntawm ib tug rotating electromagnetic moments, uas teem lub rotor nyob rau hauv cov kev taw qhia.
Tsis tas li ntawd, cov yam ntxwv ntawm lub tshuab hluav taws xob induction yog ua raws li nws cov haujlwm hauv ob hom. Nws tuaj yeem ua haujlwm raws li lub tshuab hluav taws xob lossis lub tshuab hluav taws xob. Vim tias cov khoom zoo li no, nws feem ntau yog siv los ua lub xov tooj ntawm tes ntawm hluav taws xob, nrog rau ntau yam khoom siv thev naus laus zis thiab khoom siv.
Xav txog cov cuab yeej ntawm asynchronous lub cev muaj zog, nws yuav tsum tau sau tseg nws cov ntsiab lus pib, suav nrog lub pib capacitor thiab pib winding nrog kev ua haujlwm siab. Lawv txawv los ntawm lawv cov nqi qis thiab simplicity, tsis tas yuav tsum tau ntxiv cov theem hloov pauv. Raws li qhov tsis zoo, nws yuav tsum tau sau tseg qhov tsis muaj zog tsim ntawm qhov pib winding, uas feem ntau ua tsis tiav.
Induction lub cev muaj zog ntaus ntawv thiab cov cai tswj xyuas
Qhov pib Circuit Court ntawm lub asynchronous lub cev muaj zog tuaj yeem txhim kho los ntawm kev sib txuas hauv cov koob nrog cov pib capacitor winding. Tom qab lub capacitor raug txiav tawm, tag nrho cov yam ntxwv ntawm lub cav yog khaws cia tag nrho. Heev feem ntau, lub switching Circuit Court ntawm lub asynchronous lub cev muaj zog ua hauj lwm winding, muab faib ua ob theem txuas nrog series. Nyob rau hauv cov ntaub ntawv no, lub spatial hloov ntawm lub axes yog nyob rau hauv thaj tsam ntawm 105 mus rau 120 degrees. Cov motors nrog cov ncej shielded yog siv rau cov kiv cua cua sov.
Cov cuab yeej ntawm peb-theem asynchronous lub cev muaj zog yuav tsum tau kuaj xyuas txhua hnub, kev tu sab nraud thiab kho cov haujlwm. Ob zaug ib hlis lossis ntau dua, lub cav yuav tsum tau tshuab los ntawm sab hauv nrog cov cua compressed. Kev saib xyuas tshwj xeeb yuav tsum tau them rau cov kabmob lubrication, uas yuav tsum tsim nyog rau hom tshwj xeeb ntawm lub cev muaj zog. Kev hloov pauv ntawm cov roj nplua nyeem yog ua tiav ob zaug hauv lub xyoo, nrog rau kev sib xyaw ua ke ntawm cov bearings nrog roj av.
Lub hauv paus ntsiab lus ntawm kev ua haujlwm ntawm asynchronous lub cev muaj zog - nws cov kev kuaj mob thiab kho
Txhawm rau tswj peb-theem asynchronous lub cev muaj zog kom yooj yim thiab siv sijhawm ntev, nws yuav tsum tau saib xyuas lub suab nrov ntawm cov bearings thaum lub sijhawm ua haujlwm. Whistling, crackling los yog khawb lub suab yuav tsum tau zam, qhia tias tsis muaj lubrication, nrog rau thuds, qhia tias clips, pob, cais yuav puas.
Nyob rau hauv qhov xwm txheej ntawm lub suab txawv txawv los yog overheating, cov bearings yuav tsum tau disassembled thiab tshuaj xyuas.. Cov roj qub raug tshem tawm, tom qab ntawd tag nrho cov seem yog yaug nrog roj av. Ua ntej muab cov bearings tshiab rau ntawm ncej, lawv yuav tsum tau preheated nyob rau hauv cov roj mus rau qhov xav tau kub. Cov roj tshiab yuav tsum sau cov ntim ua haujlwm ntawm cov kabmob los ntawm ib feem peb, sib npaug sib npaug ntawm tag nrho cov kab.
Qhov xwm txheej ntawm lub nplhaib ntiv nplhaib yog txhawm rau txheeb xyuas lawv qhov chaw. Yog hais tias lawv raug cuam tshuam los ntawm xeb, qhov saum npoo yog ntxuav nrog cov ntawv xuab zeb mos thiab so nrog kerosene. Hauv cov xwm txheej tshwj xeeb, lawv qhov tho txawv thiab sib tsoo ua tiav. Yog li, nrog kev tu ib txwm ntawm lub cav, nws yuav tuaj yeem ua haujlwm rau nws lub sijhawm lav thiab ua haujlwm ntev dua.
