Tam sim no, zaus hloov dua siab tswj thev naus laus zis tau dhau los ua qhov kev tswj hwm ceev ceev, uas tuaj yeem siv dav hauv ntau yam lag luam rau stepless variable tsav ceev. Raws li cov zaus hloov pauv yog ntau dua thiab ntau dua qub siv hauv kev tswj hwm kev lag luam, nws ua rau kev siv cov kev hloov pauv hloov pauv ntau dua thiab ntau dua thiab
Ib lub cev muaj zog, tseem hu ua hluav taws xob lub cev muaj zog, yog cov khoom siv hluav taws xob uas hloov lub zog hluav taws xob rau hauv lub zog hluav taws xob. When the current flows in a magnetic field, the motor that operates by receiving power for rotary motion is relatively common, but there exist many types of motors, if the motor can be roughly divided into two types, AC and DC, according to the type of drive power used, and these motors can be further divided into subtypes.
Piv nrog rau tib neeg lub cev muaj zog, inverter motors thiab cov motors zoo tib yam hauv tsos tsis yog qhov chaw sib txawv, txawm li cas los xij, nyob rau hauv cov kev ua haujlwm lossis siv thiab lwm qhov chaw sib txawv. Txawm li cas los xij, ntau tus neeg muas zaub tsis paub hom tsav twg los xaiv thaum kev yuav khoom. Hauv qab no peb yuav siv Inverter Motors thiab cov tsheb loj thiab qhia qhov piv txwv thiab luv luv qhia lawv qhov sib txawv.
Inverter lub cev muaj zog thiab lub cev muaj zog zoo tib yam yog dab tsi
Inverter lub cev muaj zog kuj tseem hu ua ntau zaus hloov dua siab tshiab lub cev muaj zog, los ntawm zaus hloov dua siab tshiab peb feem ntau hais, txhawm rau tswj lub cev muaj zog. Qhov tseeb, ntxiv rau qhov inverter lub cev muaj zog nws tus kheej, xws li peb {}}}}}}}}}}} {}} {} {} {} {} {} Cov kev hloov pauv kuj tseem tuaj yeem paub txoj haujlwm ntawm cov haujlwm hauv inverter. Nws yog tus cwj pwm los ntawm zaus tuaj yeem hloov kho raws li lub thauj mus los hloov cov tshuab hluav taws xob, koj tuaj yeem siv cov khoom siv qis dua los txo cov zaus, kom lub cev muaj zog kom tau txais lub zog txhim khu kev qha; xws li loads sib dua, koj tuaj yeem siv Inverter cov motors kom txo tau cov zaus kom ua tiav lub hom phiaj ntawm kev txo qis qhov tam sim no thiab nrawm, yog li kom txuag lub zog. Cov roj motors dog dig, tseem hu ua Motors, yog hom hluav taws xob siv hluav taws xob, siv rau cov khoom siv hluav taws xob, uas tuaj yeem muab cov lus qhia ntawm caj npab ntawm kev siv hluav taws xob. Nws cov yam ntxwv yog ntev npaum li lub zog yog nyob, nws tuaj yeem hloov, ntev npaum li qhov kev sib hloov, thiab nws tsis tuaj yeem hloov kho nrawm, thiab nrawm tuaj yeem tsuas yog qeeb qeeb los ntawm lub reducer.
Zaus hloov pauv lub cev muaj zog thiab cov kev ua kom zoo dua ntawm cov khoom siv hluav taws xob, tab sis kuj tseem muaj kev hloov pauv ntawm hluav taws xob ntau dua, tab sis kuj tseem muaj zog ntawm cov khoom siv hluav taws xob tsis yooj yim yog qhov sib nqus ntawm cov khoom sib nqus tsis yooj yim rau qhov tsis yooj yim; Thiab cov qauv ntawm cov neeg muaj peev txheej zoo ib yam yog yooj yim thiab yooj yim tswj, tus nqi kuj tseem siv ntau dua li cov kev hloov pauv hloov pauv, tab sis nws yuav raug siv rau kev kub ntxhov. Tab sis kev siv yuav raug hlawv vim yog overheating.
Zaus hloov pauv lub cev muaj zog thiab lub cev muaj zog zoo tib yam dab tsi yog qhov sib txawv
1, cov cua sov dissipation muaj ntau: cov kiv cua zoo thiab txias kiv cua siv tib txoj kab thiab cov kiv cua txias nrog cov kab sib cais. Yog li ntawd, thaum muaj zaus ntawm lub cev muaj zog zoo tib yam tsawg dhau, nws yuav raug hlawv vim qhov kub siab. Cov motors zoo tib yam yog tsim raws li ntau zaus ntawm cov nqi hluav taws xob thiab tsuas yog ua kom muaj zog nyob rau hauv cov kev ntsuas kub, thiab tsuas yog inverter motors zoo dua li cov neeg muaj tsheb.
2, rwb thaiv tsev theem yog txawv: inverter lub cev muaj zog yuav tsum tau withstand siab electromagnetic teb, yog li nws rwb thaiv tsev theem yog siab dua li cov neeg muaj zog. Nyob rau hauv ib txwm muaj xwm txheej, cov neeg muaj lub cev muaj zog tsis tuaj yeem siv rau cov kev hloov pauv hloov pauv ntawm cov nqi hloov pauv ntau dua, feem ntau yog siv cov kiv cua thiab cov twj siv hluav taws xob hauv lub zog {}} kev hloov pauv.
3, Qhov kev pabcuam lub neej yog txawv: Qhov kev pabcuam lub neej ntawm kev nquag hloov dua siab tshiab lub cev muaj zog yog feem ntau ntev dua li lub cev muaj zog. Lub cev muaj zog zoo tib yam hauv kev ua haujlwm, cov chaw nqa hluav taws xob tuaj yeem mus txog ob peb txhiab rau ntau dua li kaum kilohertz, uas yuav ua rau lub cev muaj zog siab dua}}}}}}}}}}} Lub cev muaj zog inverter tuaj yeem ua haujlwm nyob rau hauv lub tshuab hluav taws xob ntawm lub tshuab hluav taws xob, nws qhov kev ua tau zoo yuav ruaj khov, thiab muaj kev pabcuam ntev dua. Inverter lub cev muaj zog yog ib hom zaus hloov kho kom tswj lub zog, thiab cov kev ua kom sov thiab kev pab cuam lub neej thiab yog li ntawm qee qhov tsis zoo ib yam.
Hauv qee cov cuab yeej qub qub kho dua tshiab, txhawm rau ua tiav qee qhov tshwm sim, cov zaus hloov pauv yog siv los tsav lub cev muaj zog. Txhawm rau kom txuag peev, peb {-} theem asynchronous motors yuav tsum tau siv ntau li ntau tau.
Nyob rau hauv dab tsi tshwm sim yog nws pom zoo kom siv cov tshuab hluav taws xob tshwj xeeb?
① Ua haujlwm zaus> 50Hz lossis tseem txog 200 ~ 400Hz, feem ntau zoo li-}}}}}}}} {pawv muaj zog thiab bearings tsis tuaj yeem tiv thaiv.
② Kev Ua Haujlwm Ntau zaus<10HZ, the load is large and to work continuously for a long time, ordinary three-phase asynchronous motors rely on the machine's airfoils can not meet the cooling needs of the motor, the motor will be seriously overheated, especially easy to damage the motor.
Lub cev muaj zog thiab saib lub load ceev piv d ntau dua lossis sib npaug rau 10 thiab nquag hloov pauv hauv kev ua haujlwm ntawm bar (d {}} nmax / nmin).
④ Qhov kev tswj nrawm nrawm D yog loj, lub voj voog ua haujlwm yog luv luv, lub sij hawm tseem loj, nws yuav tsum tau paub txog hom haujlwm ua haujlwm ntawm lub zog kev tawm tsam braking.
⑤ Yog tias nws tsim nyog siv inverter lub cev muaj zog vim tias qhov kev xav tau ntawm kev kis tau, siv inverter lub cev muaj zog.
Inverter lub cev muaj zog muaj cov cwj pwm hauv qab no.
①tail Lub cev muaj zog kub dissipation, uas yog tsav los ntawm kev ywj pheej constant {}}} Lub cev muaj zog tas li, kev ywj pheej ntawm qhov ceev ntawm inverter lub cev muaj zog.
② Cov neeg kho tshuab lub zog ntawm inverter lub cev muaj zog tsim kom ntseeg tau tias lub cev muaj zog siv tau ntawm qhov nrawm thiab muaj kev nyab xeeb thiab txhim khu kev qha.
③ Qhov zoo tshaj plaws ntau ntawm cov qauv sib nqus yog qhov loj, nws tuaj yeem hloov kho kom muaj cov kev siv ntau tshaj plaws thiab kev siv qis tshaj plaws.
④ tsim qauv rwb thaiv tau muaj ntau dua li cov nquag peb {{{}}} paim hluav taws xob asynchronous lub zog, uas muaj peev xwm ntau dua thiab siab dua feem kub hluav taws xob.
⑤ Thaum khiav ntawm qhov kev kub ceev, lub suab nrov, kev tsim cov khoom tsim tawm tsis siab tshaj li cov neeg zoo li cov qauv asynchronous ntawm tib tus qauv.
