電磁式振動盤的工作原理：

振(zhen)動(dong)盤(pan)是由振(zhen)動(dong)板(ban)(ban),電(dian)磁(ci)鐵,銜鐵,彈(dan)簧片(pian),安裝(zhuang)座,減振(zhen)膠(jiao)墊(dian)組成,利用(yong)(yong)控制器產生與系統固有頻率相同的脈沖(chong)電(dian)流使電(dian)磁(ci)鐵勵磁(ci)后(hou),系統發(fa)生共振(zhen),銜鐵及(ji)振(zhen)動(dong)板(ban)(ban)會快速(su)的拉向(xiang)(xiang)電(dian)磁(ci)鐵,因為下降(jiang)速(su)度很快,所(suo)以物(wu)料(liao)會浮在空中,并在重力作(zuo)用(yong)(yong)下落向(xiang)(xiang)料(liao)盤(pan),接著在彈(dan)簧片(pian)的作(zuo)用(yong)(yong)下,銜鐵及(ji)振(zhen)動(dong)板(ban)(ban)又被推回(hui),這時使料(liao)盤(pan)內的物(wu)料(liao)向(xiang)(xiang)前方移動(dong),該作(zuo)用(yong)(yong)以每分鐘3000---10000次(ci)或(huo)更(geng)高(gao)的次(ci)數反復(fu)進行,使用(yong)(yong)權料(liao)盤(pan)內的物(wu)料(liao)平滑移動(dong).

交(jiao)流(liu)電(dian)壓使電(dian)磁(ci)(ci)鐵產(chan)生(sheng)磁(ci)(ci)場,由于(yu)頻率很高(gao),故產(chan)生(sheng)的(de)磁(ci)(ci)力也是(shi)瞬(shun)間(jian)(jian)變化的(de),底盤下面有(you)3---6組(zu)一定的(de)角度(du)彈(dan)簧(huang)片,當(dang)電(dian)磁(ci)(ci)鐵同交(jiao)流(liu)電(dian)瞬(shun)間(jian)(jian)產(chan)生(sheng)磁(ci)(ci)場,彈(dan)簧(huang)片受(shou)壓,當(dang)電(dian)壓正弦波變化的(de)時候,彈(dan)簧(huang)片彈(dan)回來,就產(chan)生(sheng)了力.
