電磁式振動盤的工作原理：

振動(dong)盤(pan)是由振動(dong)板(ban),電(dian)磁鐵(tie),銜(xian)(xian)鐵(tie),彈簧(huang)片(pian),安裝座(zuo),減振膠墊組成,利用(yong)控制器產生與系(xi)統固有(you)頻率相同(tong)的脈沖電(dian)流使電(dian)磁鐵(tie)勵(li)磁后(hou),系(xi)統發生共(gong)振,銜(xian)(xian)鐵(tie)及振動(dong)板(ban)會(hui)(hui)快(kuai)(kuai)速的拉向(xiang)電(dian)磁鐵(tie),因為下(xia)降速度(du)很快(kuai)(kuai),所以(yi)物(wu)料(liao)(liao)會(hui)(hui)浮在(zai)空中,并在(zai)重力(li)作(zuo)(zuo)(zuo)用(yong)下(xia)落向(xiang)料(liao)(liao)盤(pan),接著在(zai)彈簧(huang)片(pian)的作(zuo)(zuo)(zuo)用(yong)下(xia),銜(xian)(xian)鐵(tie)及振動(dong)板(ban)又被推回,這時使料(liao)(liao)盤(pan)內的物(wu)料(liao)(liao)向(xiang)前方移動(dong),該作(zuo)(zuo)(zuo)用(yong)以(yi)每分鐘3000---10000次(ci)或更高(gao)的次(ci)數反(fan)復進行(xing),使用(yong)權料(liao)(liao)盤(pan)內的物(wu)料(liao)(liao)平滑移動(dong).

交流電(dian)(dian)(dian)壓使電(dian)(dian)(dian)磁(ci)鐵產(chan)生磁(ci)場(chang),由于頻率很高,故產(chan)生的(de)磁(ci)力也是瞬間(jian)變化(hua)的(de),底盤下面有3---6組一(yi)定的(de)角度彈簧片(pian),當(dang)電(dian)(dian)(dian)磁(ci)鐵同(tong)交流電(dian)(dian)(dian)瞬間(jian)產(chan)生磁(ci)場(chang),彈簧片(pian)受壓,當(dang)電(dian)(dian)(dian)壓正(zheng)弦波變化(hua)的(de)時(shi)候(hou),彈簧片(pian)彈回(hui)來,就產(chan)生了力.
