電磁式振動盤的工作原理：

振動(dong)盤(pan)是由振動(dong)板,電(dian)磁鐵(tie)(tie),銜(xian)鐵(tie)(tie),彈簧(huang)片,安裝(zhuang)座,減振膠墊(dian)組(zu)成,利用(yong)(yong)控制器產(chan)生與系統(tong)固有(you)頻率相同的脈沖電(dian)流(liu)使電(dian)磁鐵(tie)(tie)勵磁后,系統(tong)發生共振,銜(xian)鐵(tie)(tie)及(ji)振動(dong)板會快速(su)的拉(la)向(xiang)(xiang)電(dian)磁鐵(tie)(tie),因為下降(jiang)速(su)度很快,所以(yi)物料會浮在(zai)空中,并在(zai)重力作(zuo)用(yong)(yong)下落(luo)向(xiang)(xiang)料盤(pan),接著在(zai)彈簧(huang)片的作(zuo)用(yong)(yong)下,銜(xian)鐵(tie)(tie)及(ji)振動(dong)板又(you)被推回(hui),這時使料盤(pan)內(nei)的物料向(xiang)(xiang)前方移(yi)動(dong),該作(zuo)用(yong)(yong)以(yi)每分鐘3000---10000次或(huo)更(geng)高(gao)的次數反復進行,使用(yong)(yong)權料盤(pan)內(nei)的物料平滑移(yi)動(dong).

交(jiao)流電(dian)壓使電(dian)磁(ci)(ci)(ci)鐵產(chan)生(sheng)磁(ci)(ci)(ci)場(chang),由于(yu)頻率很(hen)高,故產(chan)生(sheng)的(de)磁(ci)(ci)(ci)力(li)也(ye)是瞬(shun)間變(bian)化的(de),底盤(pan)下面(mian)有3---6組(zu)一定的(de)角度彈簧片(pian),當電(dian)磁(ci)(ci)(ci)鐵同交(jiao)流電(dian)瞬(shun)間產(chan)生(sheng)磁(ci)(ci)(ci)場(chang),彈簧片(pian)受壓,當電(dian)壓正弦(xian)波變(bian)化的(de)時候,彈簧片(pian)彈回來,就產(chan)生(sheng)了力(li).
