電磁式振動盤的工作原理：

振動(dong)盤是由振動(dong)板,電(dian)(dian)磁鐵,銜(xian)鐵,彈簧(huang)片,安裝座,減振膠(jiao)墊(dian)組成(cheng),利用(yong)(yong)控制器(qi)產生(sheng)與系(xi)統固有頻率相(xiang)同的脈沖電(dian)(dian)流使電(dian)(dian)磁鐵勵磁后,系(xi)統發(fa)生(sheng)共振,銜(xian)鐵及(ji)振動(dong)板會(hui)快速(su)的拉向電(dian)(dian)磁鐵,因(yin)為下(xia)降速(su)度很快,所(suo)以(yi)物料(liao)(liao)(liao)會(hui)浮在空中,并在重力作(zuo)用(yong)(yong)下(xia)落向料(liao)(liao)(liao)盤,接著(zhu)在彈簧(huang)片的作(zuo)用(yong)(yong)下(xia),銜(xian)鐵及(ji)振動(dong)板又被推回,這時使料(liao)(liao)(liao)盤內(nei)的物料(liao)(liao)(liao)向前方移(yi)動(dong),該作(zuo)用(yong)(yong)以(yi)每分鐘(zhong)3000---10000次或更高的次數(shu)反復(fu)進(jin)行(xing),使用(yong)(yong)權料(liao)(liao)(liao)盤內(nei)的物料(liao)(liao)(liao)平滑(hua)移(yi)動(dong).

交流(liu)電(dian)(dian)壓(ya)使電(dian)(dian)磁(ci)(ci)鐵產生(sheng)磁(ci)(ci)場,由于(yu)頻率很(hen)高,故產生(sheng)的(de)(de)磁(ci)(ci)力(li)也是(shi)瞬(shun)間變化的(de)(de),底盤下面有3---6組一(yi)定的(de)(de)角度(du)彈(dan)(dan)簧片,當電(dian)(dian)磁(ci)(ci)鐵同交流(liu)電(dian)(dian)瞬(shun)間產生(sheng)磁(ci)(ci)場,彈(dan)(dan)簧片受壓(ya),當電(dian)(dian)壓(ya)正弦波(bo)變化的(de)(de)時候,彈(dan)(dan)簧片彈(dan)(dan)回來,就產生(sheng)了力(li).
