電磁式振動盤的工作原理：

振(zhen)動(dong)(dong)(dong)盤(pan)是由振(zhen)動(dong)(dong)(dong)板(ban),電磁(ci)鐵(tie),銜(xian)(xian)鐵(tie),彈(dan)簧片(pian),安裝座,減振(zhen)膠墊組成,利用(yong)控制器產生(sheng)與系統(tong)固有頻(pin)率相同的(de)(de)脈沖(chong)電流使(shi)電磁(ci)鐵(tie)勵磁(ci)后,系統(tong)發生(sheng)共振(zhen),銜(xian)(xian)鐵(tie)及振(zhen)動(dong)(dong)(dong)板(ban)會(hui)快速的(de)(de)拉向電磁(ci)鐵(tie),因為下(xia)降速度很快,所以物料(liao)(liao)會(hui)浮(fu)在空中(zhong),并在重(zhong)力(li)作(zuo)用(yong)下(xia)落向料(liao)(liao)盤(pan),接著(zhu)在彈(dan)簧片(pian)的(de)(de)作(zuo)用(yong)下(xia),銜(xian)(xian)鐵(tie)及振(zhen)動(dong)(dong)(dong)板(ban)又被(bei)推回,這時使(shi)料(liao)(liao)盤(pan)內的(de)(de)物料(liao)(liao)向前(qian)方移動(dong)(dong)(dong),該作(zuo)用(yong)以每分鐘3000---10000次(ci)或更(geng)高(gao)的(de)(de)次(ci)數反復進(jin)行,使(shi)用(yong)權料(liao)(liao)盤(pan)內的(de)(de)物料(liao)(liao)平(ping)滑移動(dong)(dong)(dong).

交(jiao)流電(dian)(dian)壓(ya)使電(dian)(dian)磁鐵(tie)產(chan)(chan)(chan)生(sheng)磁場(chang),由于頻率很高,故產(chan)(chan)(chan)生(sheng)的(de)磁力也是(shi)瞬(shun)間變(bian)化的(de),底盤下面有(you)3---6組一定的(de)角度彈(dan)簧(huang)片,當(dang)電(dian)(dian)磁鐵(tie)同交(jiao)流電(dian)(dian)瞬(shun)間產(chan)(chan)(chan)生(sheng)磁場(chang),彈(dan)簧(huang)片受壓(ya),當(dang)電(dian)(dian)壓(ya)正(zheng)弦波變(bian)化的(de)時候,彈(dan)簧(huang)片彈(dan)回來,就產(chan)(chan)(chan)生(sheng)了力.
