Chinoshandura mafrequency - kana kuti variable frequency drive (VFD) - chishandiso chemagetsi chinoshandura magetsi ane frequency imwe kuenda kune magetsi ane frequency imwe. Voltage inowanzo fanana isati yatanga uye yapera. Mafrequency converters anowanzo shandiswa kudzora kumhanya kwemamota anoshandiswa kufambisa mapombi nemafeni.
Chinoshandura mafrequency mudziyo wemagetsi unoshandura magetsi ane frequency imwe kuenda kune magetsi ane frequency imwe. Voltage inowanzo fanana isati yatanga uye yapera. Mafrequency converters anowanzo shandiswa kudzora kumhanya kwemamota anoshandiswa kutyaira mapombi nemafeni.
Muenzaniso unotevera unoratidza kuti izvi zvinoshanda sei:
Fani inopihwa simba remagetsi re400 VAC, 50 Hz. Pa frequency iyi (50 Hz), feni inogona kumhanya nekumhanya kwakati. Kuti feni imhanye nekukurumidza, frequency converter inoshandiswa kuwedzera frequency kusvika (semuenzaniso) 70 Hz. Neimwe nzira, frequency inogona kushandurwa kuita 40 Hz kana feni ichida kumhanya zvishoma.
Hamudi kuisa michina panzvimbo yemagetsi isiriyo kana kuti munogona kubvumira utsi kuti hubude mumidziyo yenyu. Uye utsi hwacho hwakaita se "genie iri mubhodhoro", kana hwabuda mumudziyo wemagetsi, hamugone kuudzosera zvakare ... Midziyo mikuru uye yezvikamu zvitatu haigone kushanda pafrequency isiriyo sezvo frequency isiriyo inogona kukonzera kukuvara kana kupera nguva isati yakwana pamidziyo.
Saka, nzira yekusiyanisa chinoshandura frequency chaiyo chinoshandiswa pamuchina wekugezesa mota icho chichava chinangwa chikuru.
Kutaura zvazviri, vanenge vatengesi vanoti vane converter uye vanoisa pamuchina wekugezesa mota. Asi haisi frequency converter chaiyo inogona kuchinja voltage uye kumhanya kwemuchina wekugezesa mota. Kazhinji, imota diki ye0.4 inoshandiswa pamuchina unofamba, uye haigone kugadzira mamodheru akasiyana-siyana anoti Hi&low pressure yemvura yekupfapfaidza uye Hi&low speed yemafeni. Zvakatoipa ndezvokuti, kana isiri frequency converter, muchina paunotanga kushanda, instant current inopetwa ka6-7 pane general current, zvinoita kuti circus ikuvare uye magetsi aparare.
Muchina wekuwachisa mota weCBK unoshandisa tekinoroji ye18.5kw frequency converter kuti ufambise, uye nekuda kwekumanikidzwa kwemvura kwakanyanya uye kumhanya kwakanyanya uye kwakaderera kwemafeni, kushandiswa kwemagetsi kuchaderedzwa neinopfuura 15%, zvinoreva kuti muridzi anogona kugadzirira chero nzira yaanoda. Saka, muchina wekuwachisa mota weCBK unogona kuderedza kudiwa kwekugadzirisa uye mari inouya nawo.
Kazhinji, chero chinhu chine mota chinoda frequency converter, uye muchina wekuwachisa mota weCBK unogona kuita izvozvo.
