電磁式振動盤的工作原理：

振(zhen)動(dong)(dong)盤(pan)(pan)是由(you)振(zhen)動(dong)(dong)板(ban),電(dian)(dian)磁(ci)(ci)鐵,銜(xian)鐵,彈簧片,安(an)裝座,減振(zhen)膠墊組成,利(li)用(yong)控制(zhi)器產生與系統(tong)固有頻率(lv)相同(tong)的(de)脈(mo)沖電(dian)(dian)流使(shi)電(dian)(dian)磁(ci)(ci)鐵勵(li)磁(ci)(ci)后,系統(tong)發生共(gong)振(zhen),銜(xian)鐵及振(zhen)動(dong)(dong)板(ban)會(hui)快(kuai)速的(de)拉向電(dian)(dian)磁(ci)(ci)鐵,因為下降速度(du)很快(kuai),所以物料(liao)(liao)會(hui)浮在(zai)(zai)空(kong)中,并在(zai)(zai)重力作用(yong)下落向料(liao)(liao)盤(pan)(pan),接著(zhu)在(zai)(zai)彈簧片的(de)作用(yong)下,銜(xian)鐵及振(zhen)動(dong)(dong)板(ban)又(you)被推(tui)回,這(zhe)時(shi)使(shi)料(liao)(liao)盤(pan)(pan)內(nei)的(de)物料(liao)(liao)向前(qian)方移動(dong)(dong),該(gai)作用(yong)以每分鐘3000---10000次或更(geng)高的(de)次數反復進行,使(shi)用(yong)權料(liao)(liao)盤(pan)(pan)內(nei)的(de)物料(liao)(liao)平(ping)滑移動(dong)(dong).

交流電(dian)(dian)壓(ya)(ya)使電(dian)(dian)磁鐵產(chan)生磁場(chang),由于頻(pin)率很(hen)高(gao),故產(chan)生的(de)(de)磁力也是瞬間變化(hua)的(de)(de),底盤下(xia)面有3---6組一定的(de)(de)角度彈(dan)簧片(pian),當電(dian)(dian)磁鐵同交流電(dian)(dian)瞬間產(chan)生磁場(chang),彈(dan)簧片(pian)受壓(ya)(ya),當電(dian)(dian)壓(ya)(ya)正弦波變化(hua)的(de)(de)時候,彈(dan)簧片(pian)彈(dan)回來,就產(chan)生了力.
