電磁式振動盤的工作原理：

振(zhen)動(dong)(dong)盤(pan)是(shi)由(you)振(zhen)動(dong)(dong)板(ban),電(dian)磁鐵,銜(xian)鐵,彈簧片,安裝座,減振(zhen)膠墊組(zu)成,利用控(kong)制器產生與系(xi)統固有頻率相同(tong)的(de)脈(mo)沖電(dian)流使(shi)電(dian)磁鐵勵(li)磁后,系(xi)統發生共(gong)振(zhen),銜(xian)鐵及振(zhen)動(dong)(dong)板(ban)會快速(su)的(de)拉向電(dian)磁鐵,因(yin)為下降速(su)度很快,所(suo)以物料會浮在(zai)空中,并(bing)在(zai)重力作用下落向料盤(pan),接著(zhu)在(zai)彈簧片的(de)作用下,銜(xian)鐵及振(zhen)動(dong)(dong)板(ban)又(you)被(bei)推回,這時(shi)使(shi)料盤(pan)內(nei)的(de)物料向前方移動(dong)(dong),該作用以每(mei)分鐘(zhong)3000---10000次或更高的(de)次數反(fan)復(fu)進行,使(shi)用權料盤(pan)內(nei)的(de)物料平滑移動(dong)(dong).

交流(liu)電(dian)(dian)壓使電(dian)(dian)磁(ci)(ci)鐵產(chan)生磁(ci)(ci)場(chang)(chang),由于頻率很高,故產(chan)生的磁(ci)(ci)力(li)也是瞬間變(bian)化的,底盤(pan)下面有3---6組一定(ding)的角度(du)彈簧(huang)片(pian),當(dang)電(dian)(dian)磁(ci)(ci)鐵同交流(liu)電(dian)(dian)瞬間產(chan)生磁(ci)(ci)場(chang)(chang),彈簧(huang)片(pian)受壓,當(dang)電(dian)(dian)壓正弦波(bo)變(bian)化的時候,彈簧(huang)片(pian)彈回來,就(jiu)產(chan)生了力(li).
