電磁式振動盤的工作原理：

振(zhen)動(dong)(dong)盤(pan)是由振(zhen)動(dong)(dong)板(ban),電磁(ci)(ci)鐵(tie)(tie),銜(xian)(xian)鐵(tie)(tie),彈簧片(pian),安裝(zhuang)座,減振(zhen)膠墊組成,利用(yong)控制器(qi)產生與系統(tong)固有頻(pin)率相同的脈沖電流使(shi)電磁(ci)(ci)鐵(tie)(tie)勵磁(ci)(ci)后,系統(tong)發(fa)生共振(zhen),銜(xian)(xian)鐵(tie)(tie)及(ji)振(zhen)動(dong)(dong)板(ban)會(hui)(hui)快速的拉向電磁(ci)(ci)鐵(tie)(tie),因為下降速度很快,所以物料(liao)(liao)會(hui)(hui)浮在空中,并在重力作(zuo)(zuo)用(yong)下落(luo)向料(liao)(liao)盤(pan),接著(zhu)在彈簧片(pian)的作(zuo)(zuo)用(yong)下,銜(xian)(xian)鐵(tie)(tie)及(ji)振(zhen)動(dong)(dong)板(ban)又被推回,這時(shi)使(shi)料(liao)(liao)盤(pan)內的物料(liao)(liao)向前方移動(dong)(dong),該作(zuo)(zuo)用(yong)以每分鐘3000---10000次(ci)或(huo)更高(gao)的次(ci)數反復進(jin)行,使(shi)用(yong)權料(liao)(liao)盤(pan)內的物料(liao)(liao)平(ping)滑移動(dong)(dong).

交(jiao)流(liu)電(dian)(dian)壓(ya)使電(dian)(dian)磁(ci)鐵產生磁(ci)場,由于頻率很高,故(gu)產生的(de)磁(ci)力(li)也是瞬間變化的(de),底盤下面有3---6組一定的(de)角度彈(dan)簧片(pian),當(dang)電(dian)(dian)磁(ci)鐵同交(jiao)流(liu)電(dian)(dian)瞬間產生磁(ci)場,彈(dan)簧片(pian)受(shou)壓(ya),當(dang)電(dian)(dian)壓(ya)正弦(xian)波(bo)變化的(de)時候,彈(dan)簧片(pian)彈(dan)回來(lai),就產生了力(li).
