電磁式振動盤的工作原理：

振(zhen)(zhen)動(dong)(dong)(dong)盤(pan)是由振(zhen)(zhen)動(dong)(dong)(dong)板(ban),電(dian)磁(ci)鐵,銜鐵,彈簧片,安(an)裝座,減振(zhen)(zhen)膠墊(dian)組成,利用(yong)控制器產生與系(xi)統固有頻(pin)率相同的脈沖(chong)電(dian)流使電(dian)磁(ci)鐵勵磁(ci)后,系(xi)統發生共振(zhen)(zhen),銜鐵及振(zhen)(zhen)動(dong)(dong)(dong)板(ban)會快速的拉向電(dian)磁(ci)鐵,因為下降速度很快,所以物料會浮在空中,并(bing)在重力作用(yong)下落向料盤(pan),接著在彈簧片的作用(yong)下,銜鐵及振(zhen)(zhen)動(dong)(dong)(dong)板(ban)又被推回,這時使料盤(pan)內(nei)的物料向前方移動(dong)(dong)(dong),該作用(yong)以每分鐘(zhong)3000---10000次或(huo)更高的次數(shu)反復進行,使用(yong)權料盤(pan)內(nei)的物料平滑(hua)移動(dong)(dong)(dong).

交流電(dian)(dian)(dian)壓使電(dian)(dian)(dian)磁(ci)鐵(tie)產(chan)生磁(ci)場(chang),由于頻率很高,故(gu)產(chan)生的磁(ci)力(li)也是瞬間變化(hua)的,底盤下面有3---6組一定的角度彈簧(huang)片(pian)(pian),當(dang)電(dian)(dian)(dian)磁(ci)鐵(tie)同交流電(dian)(dian)(dian)瞬間產(chan)生磁(ci)場(chang),彈簧(huang)片(pian)(pian)受壓,當(dang)電(dian)(dian)(dian)壓正弦波變化(hua)的時候,彈簧(huang)片(pian)(pian)彈回來,就產(chan)生了(le)力(li).
