電磁式振動盤的工作原理：

振(zhen)(zhen)動(dong)盤是由振(zhen)(zhen)動(dong)板,電(dian)(dian)磁(ci)(ci)(ci)鐵(tie),銜鐵(tie),彈(dan)簧片,安裝座,減振(zhen)(zhen)膠墊組(zu)成(cheng),利用(yong)(yong)控制器(qi)產(chan)生(sheng)與(yu)系(xi)統固有(you)頻率相(xiang)同(tong)的(de)(de)脈沖電(dian)(dian)流使(shi)電(dian)(dian)磁(ci)(ci)(ci)鐵(tie)勵磁(ci)(ci)(ci)后,系(xi)統發生(sheng)共(gong)振(zhen)(zhen),銜鐵(tie)及振(zhen)(zhen)動(dong)板會快速的(de)(de)拉向(xiang)(xiang)電(dian)(dian)磁(ci)(ci)(ci)鐵(tie),因(yin)為下降速度(du)很快,所以(yi)物料(liao)會浮在空(kong)中,并在重(zhong)力作用(yong)(yong)下落向(xiang)(xiang)料(liao)盤,接著在彈(dan)簧片的(de)(de)作用(yong)(yong)下,銜鐵(tie)及振(zhen)(zhen)動(dong)板又被推回,這時使(shi)料(liao)盤內的(de)(de)物料(liao)向(xiang)(xiang)前方(fang)移動(dong),該作用(yong)(yong)以(yi)每分鐘3000---10000次或更高的(de)(de)次數反(fan)復進行,使(shi)用(yong)(yong)權料(liao)盤內的(de)(de)物料(liao)平滑移動(dong).

交流電壓(ya)使電磁鐵產(chan)生(sheng)磁場,由于頻率很高,故(gu)產(chan)生(sheng)的磁力也是瞬間變化(hua)的,底(di)盤下(xia)面(mian)有3---6組一定的角度彈簧片(pian)(pian),當電磁鐵同交流電瞬間產(chan)生(sheng)磁場,彈簧片(pian)(pian)受(shou)壓(ya),當電壓(ya)正弦波變化(hua)的時候,彈簧片(pian)(pian)彈回來,就產(chan)生(sheng)了力.
