Nyob rau hauv niaj hnub industrial ntau lawm, hluav taws xob motors yog dav siv.Ntau hom, cov ntaub ntawv voltage thiab voltage theem ntawm hluav taws xob motors tshwm nyob rau hauv endlessly.Cov hauv qab no yog cov lus piav qhia luv luv ntawm cov laj thawj rau kev ua haujlwm ib ntus thiab kev tiv thaiv kev tiv thaiv.
Classification ntawm motors
Fais motors tuaj yeem muab faib ua DC motors, asynchronous motors thiab synchronous motors raws li cov qauv sib txawv thiab cov qauv kev ua haujlwm.Synchronous motors tseem tuaj yeem muab faib ua cov hlau nplaum ruaj khov synchronous motors, tsis kam synchronous motors thiab hysteresis synchronous motors.Asynchronous motors tuaj yeem muab faib ua induction motors thiab AC commutator motors.Induction motors tau muab faib ua peb-theem asynchronous motors, ib-theem asynchronous motors thiab ntxoov ntxoo ncej asynchronous motors.AC commutator motors tau muab faib ua ib-theem series motors,AC thiab DC dual-lub hom phiaj motors thiab repulsion motors.
Kev puas tsuaj tshwm sim los ntawm kev ua haujlwm ib-theem ntawm peb-theem asynchronous motors
Peb-theem asynchronous motors muaj ob txoj kev xaim: Y-hom thiab Δ-type.Thaum Y-txuas lub cev muaj zog ua haujlwm nyob rau hauv ib theem, tam sim no nyob rau hauv lub disconnected theem yog xoom.Cov theem tam sim no ntawm ob theem dhau los ua kab tam sim no.Nyob rau tib lub sijhawm, nws yuav ua rau xoom taw tes drift thiab nws theem voltage kuj yuav nce.
Thaum lub cev muaj zog nrog Δ-hom xaim raug txiav tawm sab hauv, lub cev muaj zog hloov mus rau V-hom thaiv nyob rau hauv qhov kev txiav txim ntawm peb-theem fais fab mov, thiab ob-theem tam sim no nce 1.5 npaug.Thaum lub cev muaj zog nrog Δ-hom xaim raug txiav tawm sab nraud, nws yog qhov sib npaug ntawm ob-theem windings tau txuas nrog hauv series thiab peb pawg windings tau txuas nrog tib lub sijhawm ntawm ob-kab voltages.Tam sim no nyob rau hauv obwindingstxuas hauv series tseem tsis hloov.Qhov ntxiv tam sim no ntawm pab pawg thib peb yuav tau nce 1.5 npaug.
Piv txwv li, thaum lub cev muaj zog ua haujlwm nyob rau hauv ib theem, nws cov winding tam sim no nce sai, thiab cov winding thiab hlau casing kub ceev ceev, hlawv cov rwb thaiv tsev winding thiab tom qab ntawd hlawv lub cev muaj zog winding, cuam tshuam rau kev ua haujlwm ib txwm muaj.Yog tias qhov chaw nyob ib puag ncig tsis zoo, qhov chaw ib puag ncig yuav sib sau.Muaj cov khoom tawg yooj yim uas tuaj yeem ua rau hluav taws tau yooj yim thiab ua rau muaj qhov tshwm sim loj dua.
Ua rau lub cev muaj zog ib-theem kev ua haujlwm thiab kev tiv thaiv kev tiv thaiv
1.Thaum lub cev muaj zog tsis tuaj yeem pib, muaj lub suab nrov nrov, thiab lub plhaub muaj qhov kub thiab txias los yog qhov ceev yuav txo qis thaum lub sijhawm ua haujlwm, thiab qhov kub thiab txias nce, lub hwj chim yuav tsum raug txiav tam sim ntawd thiab qhov ua rau tsis ua hauj lwm yuav tsum. ua tib zoo nrhiav.Txiav txim siab seb tus mob saum toj no yog tshwm sim los ntawm qhov tsis muaj theem.
2.Thaum cov kab hluav taws xob ntawm lub ntsiab hluav taws xob yog nyias dhau los yog ntsib kev puas tsuaj sab nraud, peb-theem fais fab mov ntawm lub cev muaj zog yuav ua rau kev ua haujlwm ib-theem vim muaj kev kub hnyiab los yog sab nraud quab yuam ntaus.Lub peev xwm nqa kev nyab xeeb ntawm lub zog tseem ceeb ntawm lub cev muaj zog yog 1.5 mus rau 2.5 npaug ntawm cov ntsuas tam sim no ntawm lub cev muaj zog, thiab kev nyab xeeb nqa lub peev xwm ntawm cov kab hluav taws xob muaj feem cuam tshuam nrog txoj kev tso ntawm cov kab hluav taws xob.Tshwj xeeb tshaj yog thaum nws sib npaug los yog sib tshuam nrog cov kav dej kub, lub caij nyoog yuav tsum siab tshaj 50cm.Kev nyab xeeb nqa lub peev xwm ntawm lub hwj chim qaum uas tuaj yeem khiav mus ntev ntawm 70 ° C kub nce tuaj yeem raug kuaj xyuas los ntawm tus kws kho hluav taws xob phau ntawv qhia.Raws li kev paub dhau los, kev nyab xeeb nqa lub peev xwm ntawm tooj liab xov hlau yog 6A ib square millimeter, thiab cov xov hlau txhuas yog 4A ib square millimeter.Tsis tas li ntawd, tooj liab-aluminium hloov cov pob qij txha yuav tsum tau siv thaum tooj liab-aluminium hlau pob qij txha, kom tsis txhob oxidation ntawm tooj liab-aluminium cov ntaub ntawv thiab cuam tshuam rau kev sib koom ua ke.
3. Kev teeb tsa tsis raug ntawm huab cua hloov lossis cov khoom tiv thaiv tuaj yeem ua rau lub cev ua haujlwm ib zaug.Yog tias qhov hloov pauv huab cua me me dhau lawm, nws yuav yog vim lub zog hluav taws xob tam sim no loj dhau los hlawv cov kev sib txuas sab hauv ntawm lub tshuab hluav taws xob, ua rau theem kev tiv thaiv kev tiv thaiv loj dhau, ua haujlwm ib-theem lub cev muaj zog.Qhov ntsuas tam sim no ntawm qhov hloov pauv huab cua yuav tsum yog 1.5 txog 2.5 npaug ntawm qhov ntsuas tam sim no ntawm lub cev muaj zog.Tsis tas li ntawd, thaum lub sijhawm ua haujlwm ntawm lub cev muaj zog, nws yuav tsum tau saib xyuas tias qhov hloov pauv huab cua me me dhau lawm, lossis qhov zoo ntawm qhov hloov pauv huab cua nws tus kheej muaj teeb meem, thiab qhov hloov pauv huab cua tsim nyog yuav tsum tau hloov.
4.Cov kab kev sib txuas ntawm cov khoom hauv lub txee tswj tau raug hlawv, uas yuav ua rau lub cev muaj zog khiav hauv ib theem.Cov laj thawj rau kev sib txuas kab hluav taws xob yog raws li hauv qab no:
① Cov kab kev sib txuas yog nyias dhau, thaum lub cev muaj zog tshaj tam sim no nce, nws yuav hlawv cov kab txuas.② Cov khoom sib txuas ntawm ob qho kawg ntawm txoj kab sib txuas yog nyob rau hauv kev sib cuag tsis zoo, ua rau cov kab sib txuas ua kom sov, yog li hlawv cov kab txuas.Muaj cov tsiaj me me, xws li nas nce toj ntawm ob kab, ua rau luv luv ntawm cov kab thiab hlawv tawm ntawm txoj kab txuas.Txoj kev daws teeb meem yog: ua ntej pib ua haujlwm txhua lub sijhawm, lub txee tswj yuav tsum tau qhib kom ua tib zoo xyuas seb cov xim ntawm txhua qhov kev sib txuas tau hloov pauv, thiab seb lub rwb thaiv tsev ntawm daim tawv nqaij puas muaj qhov kub hnyiab.Cov kab hluav taws xob tsim nyog tau nruab raws li qhov kev thauj khoom tam sim no ntawm lub cev muaj zog, thiab cov khoom txuas txuas nrog raws li cov txheej txheem yuav tsum tau ua.
Peroration
Nyob rau hauv kev tsim kho, peb yuav tsum nruj me ntsis raws li cov specifications ntawm ntau yam kev tsim kho txheej txheem los xyuas kom meej qhov zoo ntawm installation.Kev saib xyuas tsis tu ncua ntawm ntau yam khoom siv thiab kev tshuaj xyuas thiab kho tsis tu ncua thaum lub sijhawm ua haujlwm yuav tsum zam qhov tsis tsim nyog poob thiab kev phom sij los ntawm kev ua haujlwm ib-theem ntawm lub cev muaj zog.
