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)(dian)磁鐵,銜(xian)鐵,彈(dan)簧(huang)片,安裝座,減(jian)振(zhen)膠墊(dian)組成,利用控制器產生與系統固有頻率相同(tong)的(de)脈(mo)沖(chong)電(dian)(dian)流(liu)使(shi)(shi)電(dian)(dian)磁鐵勵(li)磁后(hou),系統發生共(gong)振(zhen),銜(xian)鐵及振(zhen)動(dong)(dong)板(ban)會快速的(de)拉(la)向(xiang)電(dian)(dian)磁鐵,因為下降速度很快,所以物料(liao)(liao)會浮在(zai)空(kong)中,并在(zai)重力作用下落向(xiang)料(liao)(liao)盤(pan),接著在(zai)彈(dan)簧(huang)片的(de)作用下,銜(xian)鐵及振(zhen)動(dong)(dong)板(ban)又被推回(hui),這時使(shi)(shi)料(liao)(liao)盤(pan)內的(de)物料(liao)(liao)向(xiang)前方移動(dong)(dong),該作用以每分(fen)鐘(zhong)3000---10000次或更高(gao)的(de)次數反復進行,使(shi)(shi)用權料(liao)(liao)盤(pan)內的(de)物料(liao)(liao)平(ping)滑移動(dong)(dong).

交(jiao)流電壓(ya)使電磁(ci)鐵(tie)(tie)產生(sheng)磁(ci)場,由于頻率很高(gao),故產生(sheng)的(de)磁(ci)力也是瞬間變化的(de),底盤(pan)下面(mian)有3---6組一定的(de)角度(du)彈(dan)簧(huang)片(pian)(pian),當電磁(ci)鐵(tie)(tie)同交(jiao)流電瞬間產生(sheng)磁(ci)場,彈(dan)簧(huang)片(pian)(pian)受壓(ya),當電壓(ya)正弦(xian)波變化的(de)時候,彈(dan)簧(huang)片(pian)(pian)彈(dan)回(hui)來,就產生(sheng)了力.
