電磁式振動盤的工作原理：

振(zhen)動(dong)盤(pan)(pan)(pan)是(shi)由振(zhen)動(dong)板,電(dian)(dian)磁(ci)鐵(tie),銜(xian)(xian)鐵(tie),彈簧片(pian),安裝座,減振(zhen)膠(jiao)墊組成,利(li)用(yong)(yong)(yong)控制器產生與系(xi)統固有頻率相同的脈(mo)沖電(dian)(dian)流(liu)使(shi)電(dian)(dian)磁(ci)鐵(tie)勵磁(ci)后,系(xi)統發生共振(zhen),銜(xian)(xian)鐵(tie)及振(zhen)動(dong)板會(hui)快速的拉向電(dian)(dian)磁(ci)鐵(tie),因為下降(jiang)速度很快,所以(yi)(yi)物料會(hui)浮在(zai)空中,并在(zai)重力作(zuo)用(yong)(yong)(yong)下落向料盤(pan)(pan)(pan),接(jie)著在(zai)彈簧片(pian)的作(zuo)用(yong)(yong)(yong)下,銜(xian)(xian)鐵(tie)及振(zhen)動(dong)板又被推回,這時使(shi)料盤(pan)(pan)(pan)內的物料向前方移(yi)動(dong),該作(zuo)用(yong)(yong)(yong)以(yi)(yi)每分鐘3000---10000次(ci)(ci)或更高的次(ci)(ci)數反復(fu)進行,使(shi)用(yong)(yong)(yong)權料盤(pan)(pan)(pan)內的物料平滑移(yi)動(dong).

交流電壓(ya)使(shi)電磁(ci)(ci)鐵產(chan)生磁(ci)(ci)場,由(you)于頻(pin)率很高,故產(chan)生的磁(ci)(ci)力也是瞬間(jian)變化的,底盤下面(mian)有(you)3---6組一定的角度彈(dan)簧(huang)片,當電磁(ci)(ci)鐵同交流電瞬間(jian)產(chan)生磁(ci)(ci)場,彈(dan)簧(huang)片受壓(ya),當電壓(ya)正弦波變化的時(shi)候,彈(dan)簧(huang)片彈(dan)回來,就產(chan)生了力.
