電磁式振動盤的工作原理：

振(zhen)(zhen)(zhen)動(dong)盤(pan)(pan)(pan)是由振(zhen)(zhen)(zhen)動(dong)板,電(dian)(dian)(dian)磁鐵(tie)(tie),銜鐵(tie)(tie),彈(dan)簧片,安裝座,減振(zhen)(zhen)(zhen)膠墊(dian)組成,利用(yong)控制器產生與系統固有(you)頻率相同(tong)的(de)脈(mo)沖(chong)電(dian)(dian)(dian)流使(shi)電(dian)(dian)(dian)磁鐵(tie)(tie)勵磁后,系統發生共(gong)振(zhen)(zhen)(zhen),銜鐵(tie)(tie)及振(zhen)(zhen)(zhen)動(dong)板會快速的(de)拉(la)向電(dian)(dian)(dian)磁鐵(tie)(tie),因為下降速度很快,所(suo)以物(wu)料會浮在空中,并在重力作用(yong)下落向料盤(pan)(pan)(pan),接著在彈(dan)簧片的(de)作用(yong)下,銜鐵(tie)(tie)及振(zhen)(zhen)(zhen)動(dong)板又(you)被推回(hui),這時使(shi)料盤(pan)(pan)(pan)內(nei)的(de)物(wu)料向前方移動(dong),該作用(yong)以每分鐘3000---10000次或(huo)更高(gao)的(de)次數反復進行,使(shi)用(yong)權料盤(pan)(pan)(pan)內(nei)的(de)物(wu)料平滑移動(dong).

交流電(dian)(dian)壓(ya)使電(dian)(dian)磁鐵產(chan)生(sheng)磁場,由于頻(pin)率很(hen)高(gao),故產(chan)生(sheng)的(de)磁力(li)也是瞬間變(bian)化(hua)的(de),底(di)盤下面有(you)3---6組一(yi)定(ding)的(de)角度彈簧片,當電(dian)(dian)磁鐵同交流電(dian)(dian)瞬間產(chan)生(sheng)磁場,彈簧片受壓(ya),當電(dian)(dian)壓(ya)正弦波(bo)變(bian)化(hua)的(de)時候,彈簧片彈回來(lai),就產(chan)生(sheng)了力(li).
