牽引武漢電(dian)磁鐵的作用有(you)哪些？
牽(qian)引(yin)(yin)武(wu)(wu)漢電(dian)(dian)(dian)(dian)(dian)(dian)(dian)磁(ci)鐵(tie)(tie)可以被理解為(wei)主要用(yong)來(lai)牽(qian)引(yin)(yin)機械裝置、開啟或者關(guan)閉(bi)各種閥門，以執行自(zi)動(dong)控制(zhi)任(ren)務。常見的(de)(de)(de)牽(qian)引(yin)(yin)武(wu)(wu)漢電(dian)(dian)(dian)(dian)(dian)(dian)(dian)磁(ci)鐵(tie)(tie)的(de)(de)(de)鐵(tie)(tie)芯都是(shi)軟磁(ci)性材(cai)料(liao)而制(zhi)，它的(de)(de)(de)作用(yong)顯(xian)而易見，如對電(dian)(dian)(dian)(dian)(dian)(dian)(dian)動(dong)機進行制(zhi)動(dong)以達(da)到準(zhun)確停車(che)的(de)(de)(de)目的(de)(de)(de)叫制(zhi)動(dong)武(wu)(wu)漢電(dian)(dian)(dian)(dian)(dian)(dian)(dian)磁(ci)鐵(tie)(tie);電(dian)(dian)(dian)(dian)(dian)(dian)(dian)磁(ci)繼電(dian)(dian)(dian)(dian)(dian)(dian)(dian)器和接觸器的(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)磁(ci)系統、自(zi)動(dong)開關(guan)的(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)磁(ci)脫扣器及(ji)操作的(de)(de)(de)被稱為(wei)自(zi)動(dong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)器電(dian)(dian)(dian)(dian)(dian)(dian)(dian)磁(ci)控制(zhi)系統武(wu)(wu)漢電(dian)(dian)(dian)(dian)(dian)(dian)(dian)磁(ci)鐵(tie)(tie)，還有一類用(yong)于起重裝置來(lai)吊(diao)運鋼錠、鋼材(cai)、鐵(tie)(tie)砂等鐵(tie)(tie)磁(ci)性材(cai)料(liao)的(de)(de)(de)被分(fen)為(wei)起重武(wu)(wu)漢電(dian)(dian)(dian)(dian)(dian)(dian)(dian)磁(ci)鐵(tie)(tie)。
