電磁式振動盤的工作原理：

振動(dong)(dong)盤(pan)是由振動(dong)(dong)板(ban),電磁(ci)鐵(tie)(tie)(tie),銜鐵(tie)(tie)(tie),彈簧(huang)(huang)片(pian),安裝座,減(jian)振膠墊組成,利用(yong)(yong)控制器產生與(yu)系(xi)統固有頻率相同的(de)(de)脈沖電流(liu)使(shi)電磁(ci)鐵(tie)(tie)(tie)勵磁(ci)后(hou),系(xi)統發生共振,銜鐵(tie)(tie)(tie)及振動(dong)(dong)板(ban)會(hui)快(kuai)速(su)的(de)(de)拉向電磁(ci)鐵(tie)(tie)(tie),因為下(xia)(xia)降速(su)度很快(kuai),所(suo)以物(wu)料(liao)(liao)會(hui)浮在(zai)空中(zhong),并在(zai)重力(li)作(zuo)用(yong)(yong)下(xia)(xia)落(luo)向料(liao)(liao)盤(pan),接著在(zai)彈簧(huang)(huang)片(pian)的(de)(de)作(zuo)用(yong)(yong)下(xia)(xia),銜鐵(tie)(tie)(tie)及振動(dong)(dong)板(ban)又被推回,這(zhe)時使(shi)料(liao)(liao)盤(pan)內的(de)(de)物(wu)料(liao)(liao)向前(qian)方移動(dong)(dong),該作(zuo)用(yong)(yong)以每分(fen)鐘3000---10000次或更(geng)高的(de)(de)次數反復進行,使(shi)用(yong)(yong)權料(liao)(liao)盤(pan)內的(de)(de)物(wu)料(liao)(liao)平(ping)滑(hua)移動(dong)(dong).

交流電(dian)(dian)(dian)(dian)壓使電(dian)(dian)(dian)(dian)磁(ci)(ci)鐵產(chan)生(sheng)(sheng)磁(ci)(ci)場(chang),由于頻率很高,故產(chan)生(sheng)(sheng)的(de)磁(ci)(ci)力(li)也是瞬間(jian)變化的(de),底(di)盤(pan)下(xia)面有3---6組(zu)一定的(de)角度彈(dan)簧片(pian)(pian),當電(dian)(dian)(dian)(dian)磁(ci)(ci)鐵同交流電(dian)(dian)(dian)(dian)瞬間(jian)產(chan)生(sheng)(sheng)磁(ci)(ci)場(chang),彈(dan)簧片(pian)(pian)受壓,當電(dian)(dian)(dian)(dian)壓正弦波變化的(de)時候,彈(dan)簧片(pian)(pian)彈(dan)回來,就產(chan)生(sheng)(sheng)了力(li).
