電磁式振動盤的工作原理：

振動盤(pan)(pan)是由振動板(ban),電(dian)磁鐵(tie),銜(xian)鐵(tie),彈簧(huang)片,安裝(zhuang)座,減振膠墊(dian)組成,利用(yong)(yong)(yong)控制器產生與系統固有頻率相同的脈沖電(dian)流使電(dian)磁鐵(tie)勵磁后,系統發生共振,銜(xian)鐵(tie)及(ji)振動板(ban)會(hui)快速(su)的拉向電(dian)磁鐵(tie),因為下(xia)(xia)降速(su)度很快,所以物料(liao)會(hui)浮在(zai)空(kong)中(zhong),并在(zai)重力作(zuo)用(yong)(yong)(yong)下(xia)(xia)落向料(liao)盤(pan)(pan),接(jie)著在(zai)彈簧(huang)片的作(zuo)用(yong)(yong)(yong)下(xia)(xia),銜(xian)鐵(tie)及(ji)振動板(ban)又被(bei)推回(hui),這時使料(liao)盤(pan)(pan)內(nei)的物料(liao)向前方移動,該作(zuo)用(yong)(yong)(yong)以每分鐘3000---10000次或(huo)更高(gao)的次數(shu)反復進(jin)行,使用(yong)(yong)(yong)權料(liao)盤(pan)(pan)內(nei)的物料(liao)平(ping)滑移動.

交(jiao)(jiao)流電壓(ya)使電磁(ci)(ci)鐵產生(sheng)磁(ci)(ci)場(chang),由于(yu)頻率很高,故產生(sheng)的(de)(de)磁(ci)(ci)力也是瞬(shun)間變化的(de)(de),底(di)盤下面有3---6組一定的(de)(de)角度(du)彈(dan)(dan)簧片(pian),當(dang)(dang)電磁(ci)(ci)鐵同交(jiao)(jiao)流電瞬(shun)間產生(sheng)磁(ci)(ci)場(chang),彈(dan)(dan)簧片(pian)受壓(ya),當(dang)(dang)電壓(ya)正(zheng)弦波(bo)變化的(de)(de)時候,彈(dan)(dan)簧片(pian)彈(dan)(dan)回(hui)來,就產生(sheng)了力.
