A frequency converter - kana variable frequency drive (VFD) - chishandiso chemagetsi chinoshandura ikozvino ine frequency imwe kuenda kune yazvino ine imwe frequency. Iyo voltage inowanzo fanana pamberi uye mushure mekushandura frequency. Frequency converters anowanzo shandiswa kukurumidza kudzora mota dzinoshandiswa kutyaira pombi uye mafeni.
A frequency converter mudziyo wemagetsi unoshandura ikozvino ine frequency imwe kuenda kune yazvino ine imwe frequency. Iyo voltage inowanzo fanana pamberi uye mushure mekushandura frequency. Frequency converters anowanzo shandiswa kukurumidza kudzora mota dzinoshandiswa kutyaira pombi uye mafeni.
Muenzaniso unotevera unoratidza kuti izvi zvinoshanda sei:
Fani inopihwa ikozvino ye400 VAC, 50 Hz. Pane iyi frequency (50 Hz), fan inogona kumhanya neimwe kumhanya. Kuita kuti fan imhanye nekukurumidza, frequency converter inoshandiswa kuwedzera frequency kusvika (semuenzaniso) 70 Hz. Neimwe nzira, iyo frequency inogona kushandurwa kuita 40 Hz kana fan ichimhanya zvishoma.
Iwe hausi kuda kubaya midziyo mune isiriyo sosi yemagetsi kana iwe unomhanyisa njodzi yekubvumidza chiutsi kuti chibude kubva mumidziyo yako. Uye utsi hwakafanana ne "genie mubhodhoro", kana ichinge yatiza kubva mumudziyo wemagetsi, haugone kuidzosera mukati ...... Yakakura uye 3 chikamu midziyo haigone kushanda pane iyo isiriyo frequency sezvo iyo isiriyo frequency inogona kukonzera kukuvara kana kupera nguva isati yakwana. pamidziyo.
Naizvozvo, Maitiro ekusiyanisa chaiyo frequency converter inoshandisa pamushini wekugeza mota icho chichava chinangwa chikuru.
Chaizvoizvo, anenge mutengesi anoti vane chekushandura uye vanoisa pamushini wekugeza mota. Asi haisi yechokwadi frequency converter iyo inogona kushandura voltage uye kufambisa kumhanya yemuchina wekugeza mota. Kazhinji, inenge 0.4 diki mota ichiisa pairi kufamba muviri, uye haigone kumisikidza mhando dzakasiyana dziri Hi&low pressure yekupfapfaidza mvura uye Hi&low speed yemafeni. Chii chakanyanya kuipa, kana isiri frequency converter, kana muchina uchitanga kushanda, iko iko zvino kuri 6-7 nguva pane general current, zvichava nyore kukonzeresa kukuvadzwa kwesekisi uye kupera kwemagetsi.
CBK yekugezesa mota muchina unotora 18.5kw frequency converter tekinoroji kutyaira, uye nekuda kweYakakwira & Yakaderera kudzvanywa kwemvura yekupfapfaidza uye Yakakwira & Yakaderera kumhanya kwevateveri, mashandisirwo emagetsi achaponeswa neinopfuura 15%, zvinoreva kuti muridzi anogona kuseta chero maitiro aaizoita. like to. Naizvozvo, CBK yekuwachisa mota muchina unogona kuderedza kudiwa kwekugadzirisa uye mutengo unouya nawo.
Kazhinji, chero chinhu chine mota mairi chinoda frequency converter, uye CBK yekugezesa mota muchina unogona kuzviita.
