電磁式振動盤的工作原理：

振動盤(pan)是由(you)振動板,電(dian)(dian)磁(ci)鐵,銜(xian)鐵,彈簧片(pian),安裝(zhuang)座(zuo),減振膠(jiao)墊組成,利(li)用(yong)控制(zhi)器產(chan)生與系(xi)統固有頻率(lv)相同的(de)脈(mo)沖電(dian)(dian)流使電(dian)(dian)磁(ci)鐵勵磁(ci)后(hou),系(xi)統發生共振,銜(xian)鐵及振動板會(hui)快速(su)(su)的(de)拉向(xiang)電(dian)(dian)磁(ci)鐵,因為下(xia)降速(su)(su)度很快,所(suo)以物料會(hui)浮在空(kong)中,并在重力作(zuo)用(yong)下(xia)落向(xiang)料盤(pan),接著在彈簧片(pian)的(de)作(zuo)用(yong)下(xia),銜(xian)鐵及振動板又被推回,這(zhe)時使料盤(pan)內(nei)的(de)物料向(xiang)前方(fang)移(yi)動,該(gai)作(zuo)用(yong)以每(mei)分(fen)鐘3000---10000次或(huo)更高的(de)次數反復進行,使用(yong)權料盤(pan)內(nei)的(de)物料平滑移(yi)動.

交流電(dian)(dian)壓(ya)(ya)使電(dian)(dian)磁(ci)(ci)鐵產(chan)(chan)生磁(ci)(ci)場,由于頻率很高,故產(chan)(chan)生的(de)磁(ci)(ci)力(li)也是(shi)瞬間變化(hua)的(de),底盤下(xia)面(mian)有3---6組一定(ding)的(de)角度彈(dan)簧(huang)片(pian)(pian),當電(dian)(dian)磁(ci)(ci)鐵同(tong)交流電(dian)(dian)瞬間產(chan)(chan)生磁(ci)(ci)場,彈(dan)簧(huang)片(pian)(pian)受(shou)壓(ya)(ya),當電(dian)(dian)壓(ya)(ya)正弦波變化(hua)的(de)時候,彈(dan)簧(huang)片(pian)(pian)彈(dan)回(hui)來,就產(chan)(chan)生了力(li).
