電磁式振動盤的工作原理：

振(zhen)(zhen)(zhen)動(dong)盤(pan)是(shi)由振(zhen)(zhen)(zhen)動(dong)板,電(dian)(dian)磁(ci)(ci)鐵,銜(xian)鐵,彈(dan)簧片,安裝座,減振(zhen)(zhen)(zhen)膠墊組成,利用(yong)控制器產生(sheng)與(yu)系(xi)統(tong)(tong)固有頻率相同的(de)(de)(de)脈沖(chong)電(dian)(dian)流使電(dian)(dian)磁(ci)(ci)鐵勵磁(ci)(ci)后(hou),系(xi)統(tong)(tong)發(fa)生(sheng)共振(zhen)(zhen)(zhen),銜(xian)鐵及振(zhen)(zhen)(zhen)動(dong)板會快速的(de)(de)(de)拉(la)向電(dian)(dian)磁(ci)(ci)鐵,因為下降(jiang)速度很快,所以物料會浮在空中(zhong),并(bing)在重力作用(yong)下落向料盤(pan),接著(zhu)在彈(dan)簧片的(de)(de)(de)作用(yong)下,銜(xian)鐵及振(zhen)(zhen)(zhen)動(dong)板又被推回,這時使料盤(pan)內的(de)(de)(de)物料向前方移動(dong),該作用(yong)以每分鐘3000---10000次或更高的(de)(de)(de)次數反(fan)復進行,使用(yong)權(quan)料盤(pan)內的(de)(de)(de)物料平滑移動(dong).

交流電(dian)(dian)壓使電(dian)(dian)磁(ci)(ci)鐵產(chan)生(sheng)(sheng)磁(ci)(ci)場(chang)(chang),由于(yu)頻率很高(gao),故產(chan)生(sheng)(sheng)的磁(ci)(ci)力也是(shi)瞬間(jian)變化的,底盤下面(mian)有3---6組一定(ding)的角度(du)彈(dan)簧(huang)片,當(dang)電(dian)(dian)磁(ci)(ci)鐵同交流電(dian)(dian)瞬間(jian)產(chan)生(sheng)(sheng)磁(ci)(ci)場(chang)(chang),彈(dan)簧(huang)片受壓,當(dang)電(dian)(dian)壓正弦波(bo)變化的時候,彈(dan)簧(huang)片彈(dan)回(hui)來,就(jiu)產(chan)生(sheng)(sheng)了力.
