電磁式振動盤的工作原理：

振(zhen)(zhen)動(dong)盤(pan)是由振(zhen)(zhen)動(dong)板,電(dian)磁(ci)(ci)鐵,銜(xian)(xian)鐵,彈簧片,安裝座,減振(zhen)(zhen)膠墊組成,利(li)用控制器產生與系統(tong)固有頻率(lv)相同的脈沖電(dian)流使(shi)電(dian)磁(ci)(ci)鐵勵磁(ci)(ci)后,系統(tong)發生共振(zhen)(zhen),銜(xian)(xian)鐵及(ji)振(zhen)(zhen)動(dong)板會(hui)快(kuai)速的拉向(xiang)電(dian)磁(ci)(ci)鐵,因為下(xia)(xia)降速度很快(kuai),所以物(wu)料(liao)會(hui)浮在空(kong)中(zhong),并在重力作用下(xia)(xia)落向(xiang)料(liao)盤(pan),接著在彈簧片的作用下(xia)(xia),銜(xian)(xian)鐵及(ji)振(zhen)(zhen)動(dong)板又被推回,這時使(shi)料(liao)盤(pan)內的物(wu)料(liao)向(xiang)前方移(yi)動(dong),該作用以每分(fen)鐘3000---10000次或更高的次數反復(fu)進(jin)行(xing),使(shi)用權料(liao)盤(pan)內的物(wu)料(liao)平滑移(yi)動(dong).

交流電(dian)(dian)壓使電(dian)(dian)磁(ci)(ci)(ci)鐵(tie)產生磁(ci)(ci)(ci)場,由(you)于頻率(lv)很高(gao),故產生的磁(ci)(ci)(ci)力也(ye)是瞬間變化的,底盤下面有3---6組(zu)一定(ding)的角度彈(dan)簧片(pian),當電(dian)(dian)磁(ci)(ci)(ci)鐵(tie)同交流電(dian)(dian)瞬間產生磁(ci)(ci)(ci)場,彈(dan)簧片(pian)受壓,當電(dian)(dian)壓正弦波(bo)變化的時候,彈(dan)簧片(pian)彈(dan)回(hui)來(lai),就產生了力.
