Kushandiswa kweiyo chaiyo yekumira basa reDanfoss FC51 inverter
Vatengi vanowanzoda michina yemaindasitiri nemidziyo, senge yakamira yekurongedza michina, michina yekuisa, uye diki mota yekugadzira michina, kumisa nemazvo muchina spindle panzvimbo yakatarwa kana yadzikiswa. Tichifunga nezvemakwikwi akanyanya emusika, ivo vanotsvagawo mhinduro dzinodhura kuti vakwanise kumisa iyi chaiyo.
Danfoss FC51 yakatevedzana inverters inopa yakavakirwa-mukati chaiyo yekupaka basa inosangana nezvido izvi. Nekuita kwavo kwakasarudzika kwebhureki uye kukwikwidza kwakanyanya mitengo, vabuda sesarudzo yakanakira vatengi, vachiunza mhedzisiro yakafanana kune yakakwirira-yekupedzisira inverters.
Kuenzanisira, funga ichangoburwa chaiyo yekumira basa application yakaitwa neShanghai Xinling kumutengi. Iyo mechanical chimiro inoratidzwa muFigure 1.
Position yekuona sensors inoiswa kumusoro uye kuzasi kumagumo emuchina spindle, uye spindle mota inoderedza ine chiyero chekudzikisa che1:10. Tichifunga kuti mota iri kumhanya pa62Hz, zvinotora angangoita 333ms kuti spindle ipedze shanduko imwe chete, zvichibva pane inofungidzirwa mota kumhanya kwe1800rpm.
Heino mashandiro anoita iyo chaiyo yekumira basa:
Pakugamuchira murairo wekumira, mutongi anoona chiratidzo kubva ku sensor 1 uye pakarepo anogadzirisa iyo inverter yekubuda frequency kuseta kusvika 35Hz kuburikidza nekutaurirana. Izvi zvinoita kuti mota idzike kubva pa62Hz kuenda pa35Hz mukati mehafu yekuchinja, kana 165ms.
Kana iyo controller inogamuchira chiratidzo kubva ku sensor 2, inowedzera kudzikisa mota kumhanya kusvika 7Hz nenzira yakafanana. Nekuda kwekuita kwepamusoro kweFC51 inverter, aya maviri ekudzikisira maitiro anowanikwa zvakanaka uye zvakatsiga.
Pakugamuchira chiratidzo kubva ku sensor 1 zvakare, mutongi anobva abvisa terminal 33 yeiyo inverter, ichikonzera iyo chaiyo yekumira basa logic. Ichi chiito chinomisa spindle nekumhanya kwakanyanya, kuwana yakasarudzika yekudzokorora kumira chinzvimbo chechokwadi.
Chengetedza zvigadziriso zvefekitari kune mamwe maparamita asina hukama. Izvo zvinofanirwa kucherechedzwa kuti iyo chaiyo yekumira inverse logic basa reFC51 inogona chete kushandisa terminal 33.
