電磁式振動盤的工作原理：

振(zhen)動(dong)(dong)盤是由振(zhen)動(dong)(dong)板(ban),電磁(ci)鐵(tie),銜(xian)(xian)鐵(tie),彈簧片,安裝座(zuo),減振(zhen)膠墊組(zu)成(cheng),利(li)用(yong)控(kong)制(zhi)器產(chan)生(sheng)與系統固有頻(pin)率相同的(de)(de)(de)脈沖電流使電磁(ci)鐵(tie)勵磁(ci)后,系統發生(sheng)共振(zhen),銜(xian)(xian)鐵(tie)及振(zhen)動(dong)(dong)板(ban)會快速(su)(su)的(de)(de)(de)拉向(xiang)(xiang)電磁(ci)鐵(tie),因(yin)為下(xia)降(jiang)速(su)(su)度很快,所以物料會浮在空中,并在重力作(zuo)用(yong)下(xia)落向(xiang)(xiang)料盤,接(jie)著在彈簧片的(de)(de)(de)作(zuo)用(yong)下(xia),銜(xian)(xian)鐵(tie)及振(zhen)動(dong)(dong)板(ban)又被推回(hui),這時使料盤內的(de)(de)(de)物料向(xiang)(xiang)前(qian)方移動(dong)(dong),該作(zuo)用(yong)以每分鐘3000---10000次(ci)或更高的(de)(de)(de)次(ci)數反(fan)復進行,使用(yong)權料盤內的(de)(de)(de)物料平滑移動(dong)(dong).

交(jiao)流電(dian)(dian)壓使電(dian)(dian)磁(ci)(ci)鐵產生(sheng)(sheng)磁(ci)(ci)場(chang)(chang),由于頻率很高,故(gu)產生(sheng)(sheng)的磁(ci)(ci)力也是瞬間(jian)變化(hua)的,底盤下面(mian)有3---6組一定的角度(du)彈簧(huang)片(pian),當電(dian)(dian)磁(ci)(ci)鐵同(tong)交(jiao)流電(dian)(dian)瞬間(jian)產生(sheng)(sheng)磁(ci)(ci)場(chang)(chang),彈簧(huang)片(pian)受壓,當電(dian)(dian)壓正弦波變化(hua)的時候,彈簧(huang)片(pian)彈回(hui)來(lai),就產生(sheng)(sheng)了(le)力.
