電磁式振動盤的工作原理：

振(zhen)(zhen)動(dong)(dong)盤是(shi)由振(zhen)(zhen)動(dong)(dong)板,電(dian)(dian)磁(ci)(ci)鐵(tie)(tie),銜(xian)鐵(tie)(tie),彈簧(huang)片,安(an)裝座,減振(zhen)(zhen)膠墊組成,利用(yong)(yong)控制器產生(sheng)與(yu)系(xi)統固有頻率(lv)相同的(de)(de)脈沖電(dian)(dian)流使(shi)電(dian)(dian)磁(ci)(ci)鐵(tie)(tie)勵磁(ci)(ci)后,系(xi)統發生(sheng)共振(zhen)(zhen),銜(xian)鐵(tie)(tie)及振(zhen)(zhen)動(dong)(dong)板會(hui)快速的(de)(de)拉向(xiang)電(dian)(dian)磁(ci)(ci)鐵(tie)(tie),因(yin)為下(xia)降(jiang)速度很快,所(suo)以物料(liao)會(hui)浮在空中(zhong),并在重力作用(yong)(yong)下(xia)落向(xiang)料(liao)盤,接(jie)著(zhu)在彈簧(huang)片的(de)(de)作用(yong)(yong)下(xia),銜(xian)鐵(tie)(tie)及振(zhen)(zhen)動(dong)(dong)板又被推回,這時使(shi)料(liao)盤內(nei)的(de)(de)物料(liao)向(xiang)前方移動(dong)(dong),該作用(yong)(yong)以每分鐘3000---10000次(ci)或更高的(de)(de)次(ci)數反復進行,使(shi)用(yong)(yong)權料(liao)盤內(nei)的(de)(de)物料(liao)平滑(hua)移動(dong)(dong).

交(jiao)流電(dian)(dian)壓使電(dian)(dian)磁(ci)鐵產(chan)生(sheng)磁(ci)場(chang),由于頻率很(hen)高(gao),故產(chan)生(sheng)的磁(ci)力也是(shi)瞬間變化(hua)的,底盤下面(mian)有3---6組(zu)一定的角度彈(dan)簧(huang)片(pian),當電(dian)(dian)磁(ci)鐵同交(jiao)流電(dian)(dian)瞬間產(chan)生(sheng)磁(ci)場(chang),彈(dan)簧(huang)片(pian)受壓,當電(dian)(dian)壓正弦波(bo)變化(hua)的時候(hou),彈(dan)簧(huang)片(pian)彈(dan)回(hui)來,就產(chan)生(sheng)了力.
