Nrov Kev Paub Kev Tshawb Fawb Yog V / F Tswj Yog Dab Tsi?

V / f tswj, lossis voltage / zaus tswj (voltage / FreCuncy tswj), yog cov txheej txheem yooj yim rau kev hloov pauv kom tswj cov tshuab roj. Nws tswj tau qhov ceev ntawm lub cev muaj zog los ntawm kev hloov cov voltage thiab ntau zaus ntawm lub cev muaj zog nyob rau tib lub sijhawm, yog li lub cev muaj zog tuaj yeem tswj hwm kom sib nqus, yog li ua kom muaj zog ruaj khov.

Ua haujlwm ua haujlwm ntawm v / f tswj

1. Cov txheej txheem yooj yim

A. Qhov nrawm ntawm lub cev muaj zog yog sib npaug nrog cov zaus ntawm lub zog hluav taws xob: ceev= 120 * zaus / naj npawb / naj npawb ntawm ncej.

B. Txhawm rau kom lub sib nqus flux ntawm lub cev muaj zog tas li, nws yog ib qho tsim nyog los xyuas kom meej tias qhov kev sib piv ntawm voltage kom zaus (v / f piv) yog tas li.

2. Tswj txoj kev

A. Thaum lub cev muaj zog yuav hloov pauv, lub zaus hloov kho cov zis hluav taws xob thiab zaus nyob rau tib lub sijhawm kom cov piv ntawm ob ncua.

B. Piv txwv li, yog tias muaj feem txo los ntawm 50Hz, qhov ntsuas hluav taws xob rau 25z, tus ntsuas hluav taws xob tseem raug txo los ntawm cov ntsuas hluav taws xob rau ib nrab ntawm cov ntsuas hluav taws xob.

Qhov Zoo Ntawm V / F Tswj

1. Yooj yim thiab txhim khu kev qha

V / f Tswj Kev Tswj Tshuab yog paub tab, nrog ib tus qauv yooj yim, siv tau yooj yim siv thiab tswj hwm.
2. Cov haujlwm ruaj khov
Nws tuaj yeem tswj kev ua haujlwm ruaj khov ntawm lub cev muaj zog nyob rau hauv ntau qhov chaw nrawm thiab yog haum rau ntau yam kev ua haujlwm.
3. Tus nqi tsawg
Vim tias cov tswv yim tswj yooj yim, cov nqi kho vajtse thiab cov nqi software yog tsawg.

Qhov tsis zoo ntawm V / f tswj

1. Ua tsis tiav kev ua tau zoo
V / f tswj tsis tuaj yeem hloov kho lub voltage thiab ntau zaus nyob rau lub sijhawm tiag tiag, muaj lub zog qeeb zog dynamic, thiab muaj peev xwm tsis muaj peev xwm hloov kho kom haum.
2. Kev tswj hwm qhov raug
Nws muaj qhov tsis zoo hloov kho kom hloov pauv ntawm lub cev muaj zog, thiab tswj hwm cov kev tswj hwm qis thiab kev ua tau zoo.
3. Tsis zoo tsawg - ceev kev ua haujlwm
Thaum khiav ntawm kev nrawm nrawm, sib nqus flux ntawm lub cev muaj zog yog qhov nyuaj kom ua kom tas mus li, ua rau muaj kev poob qis thiab kev ua haujlwm tsis ruaj khov.

Daim Ntawv Thov V / f Tswj

1. Kiv cua thiab twj
Nws yog qhov haum rau kiv cua thiab nqus tswj nrog cov yam ntxwv tas mus li, uas tuaj yeem ua tiav lub zog - kev ua haujlwm txuag.
2. Cov conveyors thiab mixers
Nws yog siv nyob rau hauv qee zaus uas yuav tsum tau ceev tsis yog qhov siab thiab thauj cov kev hloov pauv me me.
3. Lwm tus
Nws yog qhov tsim nyog rau qee cov khoom siv uas muaj cov khoom siv tsawg rau cov lus teb zoo, xws li cov lus teb, xws li lwm yam, thiab lwm yam.
