電磁式振動盤的工作原理：

振(zhen)(zhen)動(dong)盤(pan)是由振(zhen)(zhen)動(dong)板(ban),電(dian)磁(ci)鐵(tie),銜鐵(tie),彈(dan)簧片,安裝座,減振(zhen)(zhen)膠墊組成(cheng),利用(yong)控制器產生與系(xi)統(tong)固有頻率相同(tong)的脈(mo)沖(chong)電(dian)流使電(dian)磁(ci)鐵(tie)勵(li)磁(ci)后,系(xi)統(tong)發生共振(zhen)(zhen),銜鐵(tie)及振(zhen)(zhen)動(dong)板(ban)會(hui)快速(su)的拉(la)向(xiang)電(dian)磁(ci)鐵(tie),因為下(xia)降速(su)度(du)很快,所以物料會(hui)浮在(zai)空中,并(bing)在(zai)重力作(zuo)用(yong)下(xia)落(luo)向(xiang)料盤(pan),接著在(zai)彈(dan)簧片的作(zuo)用(yong)下(xia),銜鐵(tie)及振(zhen)(zhen)動(dong)板(ban)又被推回,這時使料盤(pan)內(nei)的物料向(xiang)前方移動(dong),該(gai)作(zuo)用(yong)以每分鐘3000---10000次或(huo)更高(gao)的次數反復進行,使用(yong)權料盤(pan)內(nei)的物料平(ping)滑移動(dong).

交流(liu)電(dian)(dian)(dian)壓(ya)使電(dian)(dian)(dian)磁鐵產生(sheng)磁場(chang),由于(yu)頻率很高,故產生(sheng)的磁力也(ye)是瞬間變化(hua)的,底(di)盤下面有3---6組一定的角度彈(dan)(dan)簧(huang)片,當電(dian)(dian)(dian)磁鐵同交流(liu)電(dian)(dian)(dian)瞬間產生(sheng)磁場(chang),彈(dan)(dan)簧(huang)片受(shou)壓(ya),當電(dian)(dian)(dian)壓(ya)正弦波變化(hua)的時(shi)候,彈(dan)(dan)簧(huang)片彈(dan)(dan)回來(lai),就產生(sheng)了力.
