電磁式振動盤的工作原理：

振(zhen)動(dong)(dong)盤是由振(zhen)動(dong)(dong)板(ban),電(dian)磁鐵(tie)(tie)(tie),銜鐵(tie)(tie)(tie),彈簧(huang)片,安裝座,減振(zhen)膠墊組成,利用(yong)(yong)控制器(qi)產生與系統固有(you)頻率相同的脈沖電(dian)流使電(dian)磁鐵(tie)(tie)(tie)勵磁后,系統發生共(gong)振(zhen),銜鐵(tie)(tie)(tie)及(ji)振(zhen)動(dong)(dong)板(ban)會快(kuai)速的拉(la)向電(dian)磁鐵(tie)(tie)(tie),因為下降速度很(hen)快(kuai),所以物料(liao)(liao)會浮在空中(zhong),并在重力作(zuo)(zuo)(zuo)用(yong)(yong)下落向料(liao)(liao)盤,接著在彈簧(huang)片的作(zuo)(zuo)(zuo)用(yong)(yong)下,銜鐵(tie)(tie)(tie)及(ji)振(zhen)動(dong)(dong)板(ban)又被(bei)推回,這(zhe)時使料(liao)(liao)盤內(nei)的物料(liao)(liao)向前方(fang)移動(dong)(dong),該作(zuo)(zuo)(zuo)用(yong)(yong)以每分(fen)鐘3000---10000次或更(geng)高的次數反復進行(xing),使用(yong)(yong)權(quan)料(liao)(liao)盤內(nei)的物料(liao)(liao)平滑移動(dong)(dong).

交(jiao)流電(dian)(dian)(dian)壓(ya)使(shi)電(dian)(dian)(dian)磁(ci)鐵產生(sheng)磁(ci)場,由(you)于頻(pin)率很高,故產生(sheng)的(de)(de)(de)磁(ci)力也(ye)是瞬(shun)間(jian)(jian)變化的(de)(de)(de),底盤下面有3---6組一定的(de)(de)(de)角度彈(dan)簧(huang)片,當電(dian)(dian)(dian)磁(ci)鐵同交(jiao)流電(dian)(dian)(dian)瞬(shun)間(jian)(jian)產生(sheng)磁(ci)場,彈(dan)簧(huang)片受(shou)壓(ya),當電(dian)(dian)(dian)壓(ya)正弦波變化的(de)(de)(de)時候,彈(dan)簧(huang)片彈(dan)回來(lai),就(jiu)產生(sheng)了(le)力.
