電磁式振動盤的工作原理：

振(zhen)動(dong)盤(pan)(pan)是由振(zhen)動(dong)板(ban)(ban),電(dian)磁鐵(tie),銜(xian)鐵(tie),彈簧片,安(an)裝座,減(jian)振(zhen)膠墊組成,利用(yong)控制器產(chan)生與系統固有頻(pin)率相同的脈沖電(dian)流使(shi)電(dian)磁鐵(tie)勵磁后(hou),系統發生共振(zhen),銜(xian)鐵(tie)及振(zhen)動(dong)板(ban)(ban)會(hui)快速的拉向(xiang)電(dian)磁鐵(tie),因為下降(jiang)速度(du)很快,所(suo)以物(wu)料會(hui)浮(fu)在空中,并在重力(li)作用(yong)下落(luo)向(xiang)料盤(pan)(pan),接(jie)著在彈簧片的作用(yong)下,銜(xian)鐵(tie)及振(zhen)動(dong)板(ban)(ban)又被推回,這時(shi)使(shi)料盤(pan)(pan)內的物(wu)料向(xiang)前(qian)方移動(dong),該作用(yong)以每分鐘3000---10000次或更高的次數反復進行,使(shi)用(yong)權料盤(pan)(pan)內的物(wu)料平滑移動(dong).

交流電(dian)(dian)(dian)壓(ya)使電(dian)(dian)(dian)磁鐵產生磁場,由于頻率很高,故(gu)產生的磁力(li)也是瞬間變(bian)化的,底(di)盤下面有3---6組(zu)一(yi)定(ding)的角度彈(dan)簧片(pian)(pian),當電(dian)(dian)(dian)磁鐵同交流電(dian)(dian)(dian)瞬間產生磁場,彈(dan)簧片(pian)(pian)受壓(ya),當電(dian)(dian)(dian)壓(ya)正弦波變(bian)化的時候,彈(dan)簧片(pian)(pian)彈(dan)回來,就產生了力(li).
