Kugwiritsa ntchito inverter yeniyeni ya Danfoss FC51

Makasitomala nthawi zambiri amafunikira makina ndi zida zamafakitale, monga makina oyikamo oyimirira, makina oyika m'malo, ndi zida zazing'ono zopangira ma mota, kuti ayimitse makinawo molondola pamalo enaake akatsitsidwa. Chifukwa champikisano waukulu wamsika, amafunafunanso njira zotsika mtengo kuti akwaniritse kuyimitsidwa kolondola kumeneku.

Ma inverters a Danfoss FC51 amapereka malo oimikapo magalimoto okhazikika omwe amakwaniritsa izi. Ndi machitidwe awo apadera a braking ndi mitengo yampikisano kwambiri, atulukira ngati chisankho choyenera kwa makasitomala, akupereka zotsatira zofanana ndi zotsika mtengo kwambiri.

Kuti tichitire fanizo, lingalirani za ntchito yaposachedwa yaposachedwa yokhazikitsidwa ndi Shanghai Xinling kwa kasitomala. Mapangidwe amakina akuwonetsedwa pazithunzi 1.

Masensa ozindikira malo amaikidwa kumapeto ndi kumunsi kwa makina opota, ndipo chochepetsera ma spindle motor chimakhala ndi chiŵerengero chochepa cha 1:10. Pongoganiza kuti injiniyo ikuyenda pa 62Hz, zimatengera pafupifupi 333ms kuti spindle imalize kusinthika kumodzi, kutengera kuthamanga kwagalimoto kwa 1800rpm.

Umu ndi momwe ntchito yoyimitsa yeniyeni imagwirira ntchito:

Akalandira lamulo loyimitsa, wowongolera amazindikira chizindikiro kuchokera ku sensor 1 ndipo nthawi yomweyo amasintha ma frequency a inverter kukhala 35Hz kudzera mukulankhulana. Izi zimapangitsa kuti mota ichepe kuchoka ku 62Hz kupita ku 35Hz mkati mwa theka la kusintha, kapena 165ms.
Woyang'anira akalandira chizindikiro kuchokera ku sensa 2, amachepetsanso liwiro la injini kukhala 7Hz mofananamo. Chifukwa chakuchita bwino kwa FC51 inverter, njira ziwiri zochepetsera izi zimatheka bwino komanso mokhazikika.
Atalandiranso chizindikirocho kuchokera ku sensa 1 kachiwiri, wolamulirayo amadula nthawi yomweyo terminal 33 ya inverter, ndikuyambitsa ndondomeko yake yoyimitsa. Izi zimayimitsa chopotera pa liwiro lalikulu, kukwanitsa kuyimitsa kobwerezabwereza kwapadera.

Sungani zoikamo za fakitale pazigawo zina zosagwirizana. Tiyenera kudziwa kuti kuyimitsidwa kwa FC51 kutha kugwiritsa ntchito terminal 33 yokha.
