電磁式振動盤的工作原理：

振(zhen)動(dong)(dong)盤(pan)(pan)(pan)是由振(zhen)動(dong)(dong)板(ban)(ban)(ban),電磁鐵(tie),銜鐵(tie),彈(dan)簧片,安(an)裝座,減(jian)振(zhen)膠墊組成(cheng),利用(yong)控制器產生與系統固(gu)有頻率相同的(de)脈沖電流使電磁鐵(tie)勵磁后,系統發生共振(zhen),銜鐵(tie)及振(zhen)動(dong)(dong)板(ban)(ban)(ban)會(hui)快(kuai)速的(de)拉向(xiang)電磁鐵(tie),因為下降速度很快(kuai),所以物料(liao)會(hui)浮在(zai)空(kong)中(zhong),并在(zai)重(zhong)力(li)作(zuo)用(yong)下落向(xiang)料(liao)盤(pan)(pan)(pan),接(jie)著在(zai)彈(dan)簧片的(de)作(zuo)用(yong)下,銜鐵(tie)及振(zhen)動(dong)(dong)板(ban)(ban)(ban)又被推(tui)回,這時使料(liao)盤(pan)(pan)(pan)內(nei)的(de)物料(liao)向(xiang)前方(fang)移動(dong)(dong),該作(zuo)用(yong)以每分鐘3000---10000次或(huo)更高的(de)次數反復進(jin)行,使用(yong)權(quan)料(liao)盤(pan)(pan)(pan)內(nei)的(de)物料(liao)平滑移動(dong)(dong).

交(jiao)流電(dian)(dian)(dian)壓使電(dian)(dian)(dian)磁(ci)鐵產(chan)(chan)生(sheng)磁(ci)場,由于頻率很高,故產(chan)(chan)生(sheng)的磁(ci)力(li)也是(shi)瞬間(jian)變化(hua)的,底盤下(xia)面(mian)有3---6組一定的角度彈(dan)簧片(pian)(pian),當(dang)電(dian)(dian)(dian)磁(ci)鐵同交(jiao)流電(dian)(dian)(dian)瞬間(jian)產(chan)(chan)生(sheng)磁(ci)場,彈(dan)簧片(pian)(pian)受壓,當(dang)電(dian)(dian)(dian)壓正弦波變化(hua)的時候(hou),彈(dan)簧片(pian)(pian)彈(dan)回來(lai),就產(chan)(chan)生(sheng)了(le)力(li).
