電磁式振動盤的工作原理：

振動盤(pan)(pan)是由振動板,電(dian)磁(ci)鐵(tie),銜鐵(tie),彈(dan)簧片(pian),安裝座,減振膠(jiao)墊組(zu)成,利用(yong)(yong)控制器產生與(yu)系統(tong)固有(you)頻率相同的(de)(de)脈沖電(dian)流使(shi)電(dian)磁(ci)鐵(tie)勵磁(ci)后,系統(tong)發生共振,銜鐵(tie)及振動板會(hui)快速(su)的(de)(de)拉向(xiang)電(dian)磁(ci)鐵(tie),因為(wei)下(xia)(xia)降速(su)度很(hen)快,所以(yi)物料會(hui)浮在(zai)空中,并在(zai)重力(li)作用(yong)(yong)下(xia)(xia)落向(xiang)料盤(pan)(pan),接著(zhu)在(zai)彈(dan)簧片(pian)的(de)(de)作用(yong)(yong)下(xia)(xia),銜鐵(tie)及振動板又被推回,這時(shi)使(shi)料盤(pan)(pan)內的(de)(de)物料向(xiang)前方移(yi)動,該作用(yong)(yong)以(yi)每分鐘(zhong)3000---10000次(ci)或(huo)更高的(de)(de)次(ci)數反(fan)復進(jin)行,使(shi)用(yong)(yong)權料盤(pan)(pan)內的(de)(de)物料平滑移(yi)動.

交流(liu)電(dian)(dian)壓使電(dian)(dian)磁(ci)鐵(tie)產生(sheng)(sheng)磁(ci)場(chang)(chang),由于頻(pin)率(lv)很高(gao),故產生(sheng)(sheng)的(de)磁(ci)力也(ye)是(shi)瞬間變化(hua)的(de),底盤下(xia)面(mian)有3---6組一定的(de)角度彈簧片(pian),當電(dian)(dian)磁(ci)鐵(tie)同交流(liu)電(dian)(dian)瞬間產生(sheng)(sheng)磁(ci)場(chang)(chang),彈簧片(pian)受壓,當電(dian)(dian)壓正弦波變化(hua)的(de)時候,彈簧片(pian)彈回來,就產生(sheng)(sheng)了力.
