Chii chinonzi VFD Yakagadzirwa Ne

A variable frequency drive (VFD) chinhu chemagetsi chinodzora kumhanya uye torque yemota yemagetsi nekusiyanisa frequency uye voltage yesimba rinopihwa kwairi. VFDs, inozivikanwawo se AC dhiraivha kana inogadziriswa frequency madhiraivha, anoshandiswa kukwenenzvera kuita kwemota, kuchengetedza simba, uye kunatsiridza maitiro ekutonga mumashandisirwo akasiyana siyana.

Pane zvikonzero zvakawanda zvekugadzirisa kumhanya kwemota.
Semuyenzaniso:

Chengetedza simba uye uvandudze maitiro ehurongwa
Shandura simba mumashandisirwo akasanganiswa
Adapt drive kumhanya kuti ugadzirise zvinodiwa
Adapt drive torque kana simba rekugadzirisa zvinodiwa
Kuvandudza nzvimbo yekushanda
Deredza ruzha, sekubva kune mafeni nemapombi
Deredza kushushikana kwemechani mumakina uye kuwedzera hupenyu hwebasa
Deredza mashandisirwo emagetsi epamusoro, dzivirira kuwedzera kwemutengo wemagetsi, uye kuderedza saizi yemota inodiwa

 

Ndeapi mabhenefiti makuru ekushandisa inosiyana frequency drive?

Iyo inosiyana frequency drive inogadzirisa magetsi kuti ienderane nezvinodiwa zvesimba zvechishandiso chinotyairwa, ndiko kuti kuchengetedza kwesimba kana kukwidziridzwa kushandiswa kwesimba kunowanikwa.
Muchinyakare chakananga-on-line (DOL) mashandiro, uko mota inogara ichimhanya yakazara zvisinei nekudiwa chaiko, inosiyana frequency drive inogona kuderedza zvakanyanya kushandiswa kwesimba. Iine inosiyana frequency drive, magetsi kana mafuta ekuchengetedza e40% akajairika. Iyo snowball mhedzisiro inoreva kuti kushandisa inoshanduka frequency drive inogona zvakare kubatsira sisitimu kuderedza NOx uye CO2 emissions.

MaVFD anhasi anosanganisa networking uye diagnostics kuti zvidzore zvirinani uye kubudirira kukuru. Saka kuchengetedza kwesimba, hungwaru kudzora mota, uye kuderedzwa kwepamusoro mafungu-aya ndiwo mabhenefiti ekusarudza VFD seyako mota drive system controller.

VFDs anonyanya kushandiswa kudzora mafeni, pombi, uye macompressor, ayo anoita makumi manomwe neshanu muzana eVFD maapplication pasi rese.

Manyoro ekutanga uye akazara-mutsetse anobatika ndiwo maviri eakareruka emota controller. A soft starter chinhu chakasimba-chigadzirwa chinopa hunyoro, hunodzorwa kukwirisa kwemota kubva pakutanga kusvika kuzere kumhanya.
