Kodi VFD Yapangidwa Ndi Chiyani?

A variable frequency drive (VFD) ndi chipangizo chamagetsi chomwe chimayendetsa liwiro ndi torque ya mota yamagetsi posintha ma frequency ndi ma voliyumu amagetsi omwe amaperekedwa. Ma VFD, omwe amadziwikanso kuti ma AC drives kapena ma drive frequency osinthika, amagwiritsidwa ntchito kukhathamiritsa magwiridwe antchito agalimoto, kupulumutsa mphamvu, ndikuwongolera kuwongolera kwamachitidwe osiyanasiyana.

Pali zifukwa zambiri zosinthira liwiro la mota.
Mwachitsanzo:

Sungani mphamvu ndikuwongolera magwiridwe antchito
Sinthani mphamvu muzogwiritsa ntchito zosakanizidwa
Sinthani liwiro lagalimoto kuti ligwirizane ndi zofunikira
Sinthani torque yagalimoto kapena mphamvu kuti ikwaniritse zofunikira
Sinthani malo ogwirira ntchito
Chepetsani phokoso, monga kuchokera ku mafani ndi mapampu
Chepetsani kupsinjika kwamakina mumakina ndikukulitsa moyo wautumiki
Chepetsani kugwiritsa ntchito magetsi pachimake, pewani kukwera kwamitengo yamagetsi, ndikuchepetsa kukula kwagalimoto yofunikira

 

Kodi maubwino otani ogwiritsira ntchito ma frequency frequency drive?

Ma frequency a frequency drive amasintha magetsi kuti agwirizane ndi kufunikira kwa mphamvu pazida zoyendetsedwa, momwemo kusunga mphamvu kapena kugwiritsa ntchito bwino mphamvu kumakwaniritsidwira.
M'ntchito zachikhalidwe zachindunji (DOL), komwe injini nthawi zonse imayenda mwachangu mosasamala kanthu komwe ikufunika, kuyendetsa pafupipafupi kumatha kuchepetsa kwambiri kugwiritsa ntchito mphamvu. Ndi ma frequency frequency drive, magetsi kapena mafuta amapulumutsa 40% ndizofanana. Zotsatira za snowball zikutanthauza kuti kugwiritsa ntchito ma frequency frequency drive kungathandizenso dongosolo kuchepetsa mpweya wa NOx ndi CO2.

Ma VFD amasiku ano amaphatikiza maukonde ndi zowunikira kuti athe kuwongolera bwino komanso kuchita bwino. Chifukwa chake kupulumutsa mphamvu, kuwongolera kwanzeru zamagalimoto, komanso kuchepetsedwa kwa mafunde okwera kwambiri - izi ndi zabwino posankha VFD ngati chowongolera choyendetsa galimoto yanu.

Ma VFD amagwiritsidwa ntchito kwambiri kuwongolera mafani, mapampu, ndi ma compressor, omwe amapanga 75% ya mapulogalamu a VFD padziko lonse lapansi.

Zoyambira zofewa ndi zolumikizira zamzere zonse ndi ziwiri mwazowongolera zamagalimoto zosavuta. Choyambira chofewa ndi chipangizo chokhazikika chomwe chimapereka mathamangitsidwe odekha, oyendetsedwa bwino a mota kuyambira koyambira mpaka liwiro lonse.
