電磁式振動盤的工作原理：

振動(dong)(dong)(dong)盤是由振動(dong)(dong)(dong)板,電(dian)磁(ci)鐵,銜(xian)鐵,彈(dan)(dan)簧(huang)片,安裝座,減振膠墊組(zu)成(cheng),利(li)用(yong)控(kong)制器(qi)產(chan)生與系(xi)統(tong)固有頻(pin)率(lv)相(xiang)同的脈沖電(dian)流使電(dian)磁(ci)鐵勵磁(ci)后(hou),系(xi)統(tong)發(fa)生共振,銜(xian)鐵及振動(dong)(dong)(dong)板會快速的拉向(xiang)電(dian)磁(ci)鐵,因為下(xia)降速度很快,所以(yi)物(wu)料(liao)會浮在空中,并在重力作(zuo)用(yong)下(xia)落向(xiang)料(liao)盤,接(jie)著在彈(dan)(dan)簧(huang)片的作(zuo)用(yong)下(xia),銜(xian)鐵及振動(dong)(dong)(dong)板又(you)被推回,這時使料(liao)盤內(nei)的物(wu)料(liao)向(xiang)前(qian)方移(yi)動(dong)(dong)(dong),該作(zuo)用(yong)以(yi)每(mei)分鐘3000---10000次或更高的次數反復進行,使用(yong)權(quan)料(liao)盤內(nei)的物(wu)料(liao)平滑移(yi)動(dong)(dong)(dong).

交(jiao)流電(dian)(dian)(dian)壓使電(dian)(dian)(dian)磁(ci)(ci)鐵產生(sheng)(sheng)磁(ci)(ci)場,由于頻率很高,故產生(sheng)(sheng)的(de)磁(ci)(ci)力(li)也是瞬(shun)間變化(hua)的(de),底盤(pan)下面有3---6組一定(ding)的(de)角度彈簧片,當(dang)電(dian)(dian)(dian)磁(ci)(ci)鐵同交(jiao)流電(dian)(dian)(dian)瞬(shun)間產生(sheng)(sheng)磁(ci)(ci)場,彈簧片受壓,當(dang)電(dian)(dian)(dian)壓正(zheng)弦波變化(hua)的(de)時(shi)候,彈簧片彈回來,就產生(sheng)(sheng)了(le)力(li).
