電磁式振動盤的工作原理：

振動(dong)盤(pan)(pan)(pan)是由振動(dong)板,電(dian)磁鐵,銜鐵,彈簧片,安(an)裝座,減振膠(jiao)墊組(zu)成(cheng),利用(yong)控制器產生與系統固(gu)有頻率相(xiang)同的(de)(de)脈沖電(dian)流使(shi)電(dian)磁鐵勵磁后,系統發生共(gong)振,銜鐵及振動(dong)板會(hui)(hui)快速的(de)(de)拉向電(dian)磁鐵,因為下(xia)降速度很快,所以(yi)物料會(hui)(hui)浮(fu)在(zai)空中,并在(zai)重(zhong)力作用(yong)下(xia)落向料盤(pan)(pan)(pan),接著(zhu)在(zai)彈簧片的(de)(de)作用(yong)下(xia),銜鐵及振動(dong)板又(you)被推回(hui),這(zhe)時使(shi)料盤(pan)(pan)(pan)內(nei)的(de)(de)物料向前方移(yi)動(dong),該(gai)作用(yong)以(yi)每分鐘(zhong)3000---10000次或更(geng)高的(de)(de)次數反(fan)復進行(xing),使(shi)用(yong)權料盤(pan)(pan)(pan)內(nei)的(de)(de)物料平滑移(yi)動(dong).

交(jiao)流電(dian)(dian)(dian)壓使電(dian)(dian)(dian)磁(ci)鐵(tie)產(chan)生磁(ci)場,由于頻(pin)率很(hen)高,故(gu)產(chan)生的磁(ci)力(li)也是(shi)瞬(shun)間(jian)變化的,底盤下面有(you)3---6組一定的角度(du)彈簧(huang)片,當電(dian)(dian)(dian)磁(ci)鐵(tie)同交(jiao)流電(dian)(dian)(dian)瞬(shun)間(jian)產(chan)生磁(ci)場,彈簧(huang)片受壓,當電(dian)(dian)(dian)壓正弦波(bo)變化的時候,彈簧(huang)片彈回來,就產(chan)生了力(li).
