Qhov ncaj qha tshaj plaws ntawm asynchronous motors yog tias muaj qhov sib txawv ntawm qhov tseeb ntawm lub cev muaj zog thiab qhov ceev ntawm cov hlau nplaum, uas yog, muaj ib qho plam; piv nrog rau lwm qhov kev ua tau zoo ntawm lub cev muaj zog, lub plam ntawm lub cev muaj zog yog qhov yooj yim tshaj plaws kom tau txais, thiab txhua tus neeg siv lub cev muaj zog tuaj yeem siv qee qhov yooj yim Kev ua haujlwm yog xam.
Hauv kev qhia txog kev ua haujlwm tsis zoo ntawm lub cev muaj zog, tus nqi swb yog qhov tseem ceeb ntawm kev ua haujlwm, uas yog tus cwj pwm los ntawm qhov feem pua ntawm cov plam txheeb ze rau synchronous ceev. ntawm.Piv txwv li, lub zog zaus 2-ncej lub cev muaj zog nrog tus nqi qis ntawm 1.8% thiab 12-ncej lub cev muaj qhov sib txawv loj hauv qhov tseeb plam. Thaum tus nqi nplawm yog tib yam li 1.8%, lub plam ntawm 2-ncej fais fab zaus asynchronous lub cev muaj zog yog 3000 × 1.8% = 54 rpm, plam ntawm 12-ncej fais fab zaus lub cev muaj zog yog 500 × 1.8% = 9 rpm.Ib yam li ntawd, rau lub cev muaj zog nrog cov ncej sib txawv nrog tib txoj hlua khi, qhov sib thooj sib thooj yuav txawv heev.
Los ntawm kev sib piv kev tsom xam ntawm cov ntsiab lus ntawm plam thiab plam, plam yog tus nqi tiag, uas yog, qhov sib txawv ntawm qhov tseeb ceev thiab synchronous magnetic teb ceev, thiab chav tsev yog rev / min; thaum lub plam yog qhov sib txawv ntawm cov plam thiab cov synchronous ceev. feem pua.
Yog li ntawd, lub synchronous ceev thiab qhov tseeb ceev ntawm lub cev muaj zog yuav tsum tau paub thaum xam tus swb.Kev suav ntawm synchronous ceev ntawm lub cev muaj zog yog raws li cov qauv n = 60f / p (qhov twg f yog qhov ntsuas zaus ntawm lub cev muaj zog, thiab p yog tus naj npawb ntawm cov ncej ntawm lub cev muaj zog); Yog li ntawd, lub synchronous ceev sib haum mus rau lub hwj chim zaus 2, 4, 6, 8, 10 thiab 12 Qhov ceev yog 3000, 1500, 1000, 750, 600 thiab 500 rpm.
Qhov tseeb ceev ntawm lub cev muaj zog tuaj yeem kuaj pom los ntawm lub tachometer, thiab nws tseem suav nrog tus naj npawb ntawm kev hloov pauv ib feeb.Qhov tseeb ceev ntawm lub asynchronous lub cev muaj zog yog tsawg dua li synchronous ceev, thiab qhov sib txawv ntawm synchronous ceev thiab qhov tseeb ceev yog plam ntawm lub asynchronous lub cev muaj zog, thiab chav tsev yog rev / min.
Muaj ntau ntau hom tachometers, thiab hluav taws xob tachometers yog lub ntsiab lus dav dav: cov cuab yeej ntsuas kev sib hloov ceev tsim thiab tsim los ntawm cov cuab yeej hluav taws xob niaj hnub no feem ntau muaj cov sensors thiab cov lus qhia, thiab qee qhov kuj muaj cov teeb liab tso tawm thiab tswj.Qhov sib txawv ntawm cov cuab yeej siv hluav taws xob ntsuas hluav taws xob ceev, lub tachometer inductive tsis tas yuav nruab lub photoelectric sensor, tsis muaj lub cev muaj zog txuas ntxiv, thiab tuaj yeem siv rau hauv kev lag luam twj tso kua mis dej thiab lwm yam lag luam uas nws nyuaj rau nruab sensors.
