A frequency converter - kapena variable frequency drive (VFD) - ndi chipangizo chamagetsi chomwe chimasintha ma frequency ndi ma frequency amodzi kukhala apano ndi ma frequency ena. Mphamvu yamagetsi nthawi zambiri imakhala yofanana isanayambe komanso itatha kutembenuka. Ma frequency converters amagwiritsidwa ntchito powongolera liwiro la ma mota omwe amagwiritsidwa ntchito poyendetsa mapampu ndi mafani.
A frequency converter ndi chipangizo chamagetsi chomwe chimasintha ma frequency ndi ma frequency amodzi kukhala apano ndi ma frequency ena. Mphamvu yamagetsi nthawi zambiri imakhala yofanana isanayambe komanso itatha kutembenuka. Ma frequency converters amagwiritsidwa ntchito powongolera liwiro la ma mota omwe amagwiritsidwa ntchito poyendetsa mapampu ndi mafani.
Chitsanzo chotsatirachi chikuwonetsa momwe izi zimagwirira ntchito:
Kukupiza kumaperekedwa ndi 400 VAC, 50 Hz. Pafupipafupi (50 Hz), zimakupiza zimatha kuthamanga pa liwiro linalake. Kuti mafani azitha kuthamanga mwachangu, chosinthira pafupipafupi chimagwiritsidwa ntchito kukulitsa ma frequency mpaka (mwachitsanzo) 70 Hz. Kapenanso, ma frequency amatha kusinthidwa kukhala 40 Hz ngati fan ikuyenda pang'onopang'ono.
Simukufuna kulumikiza zida kugwero lamagetsi lolakwika kapena mungakhale pachiwopsezo cholola utsi kutuluka m'zida zanu. Ndipo utsi uli ngati "genie mu botolo", ikathawira ku chipangizo chamagetsi, simungathe kuziyikanso ... ... Zida zazikulu ndi 3 gawo sizingagwire ntchito pafupipafupi molakwika chifukwa mafupipafupi olakwika amatha kuwononga kapena kuvala msanga. pa zida.
Chifukwa chake, Momwe mungasiyanitsire chosinthira chenicheni chogwiritsa ntchito pamakina ochapira magalimoto chomwe chidzakhala cholinga chachikulu.
Kwenikweni, pafupifupi wamalonda amanena kuti ali ndi chosinthira ndikugwiritsa ntchito pa makina ochapira magalimoto. Koma sikusintha kwenikweni komwe kumatha kusintha ma voliyumu komanso kuthamanga kwa makina ochapira magalimoto. Nthawi zambiri, ndi injini yaying'ono ya 0,4 yomwe ikugwiritsidwa ntchito pathupi loyenda, ndipo siyingakhazikitse mitundu yosiyanasiyana yomwe ndi Hi&low pressure ya kupopera madzi ndi Hi&low liwiro la mafani. Choipa kwambiri, ngati sichosinthira pafupipafupi, makina akamayamba kugwira ntchito, nthawi yomweyo ndi nthawi 6-7 kuposa nthawi zonse, zimakhala zosavuta kuwononga ma circus ndikuwonongeka kwamagetsi.
Makina ochapira magalimoto a CBK amatengera ukadaulo wa 18.5kw frequency converter kuti ayendetse, ndipo chifukwa cha kuthamanga kwapamwamba & Kutsika kwa kupopera madzi ndi High & Low liwiro la mafani, kugwiritsa ntchito magetsi kudzapulumutsidwa ndi zoposa 15%, zomwe zikutanthauza kuti mwiniwake akhoza kukhazikitsa njira iliyonse yomwe angafune. ngati ku. Chifukwa chake, makina ochapira magalimoto a CBK amatha kuchepetsa kufunika kokonzanso komanso ndalama zomwe zimabwera nazo.
Nthawi zambiri, chilichonse chokhala ndi mota mkati mwake chimafunika chosinthira pafupipafupi, ndipo makina ochapira magalimoto a CBK amatha kuchita izi.
