電磁式振動盤的工作原理：

振動(dong)(dong)(dong)盤是由(you)振動(dong)(dong)(dong)板(ban),電(dian)磁(ci)鐵,銜(xian)鐵,彈簧(huang)(huang)片,安裝座,減振膠(jiao)墊組成,利用控制器產生與系(xi)統固有頻率相(xiang)同的脈沖電(dian)流使(shi)電(dian)磁(ci)鐵勵磁(ci)后(hou),系(xi)統發生共(gong)振,銜(xian)鐵及振動(dong)(dong)(dong)板(ban)會快速的拉向電(dian)磁(ci)鐵,因為下降速度很(hen)快,所以物料(liao)(liao)會浮在(zai)空中,并在(zai)重力作用下落向料(liao)(liao)盤,接(jie)著在(zai)彈簧(huang)(huang)片的作用下,銜(xian)鐵及振動(dong)(dong)(dong)板(ban)又被推回,這時(shi)使(shi)料(liao)(liao)盤內的物料(liao)(liao)向前方(fang)移(yi)動(dong)(dong)(dong),該作用以每分鐘3000---10000次(ci)或(huo)更高的次(ci)數反(fan)復進行,使(shi)用權料(liao)(liao)盤內的物料(liao)(liao)平滑移(yi)動(dong)(dong)(dong).

交(jiao)流電(dian)壓使電(dian)磁(ci)(ci)鐵(tie)產(chan)生磁(ci)(ci)場,由于頻率很(hen)高,故(gu)產(chan)生的(de)(de)磁(ci)(ci)力(li)也是瞬間(jian)(jian)變(bian)化的(de)(de),底(di)盤下面有3---6組(zu)一(yi)定的(de)(de)角度彈(dan)簧片,當電(dian)磁(ci)(ci)鐵(tie)同交(jiao)流電(dian)瞬間(jian)(jian)產(chan)生磁(ci)(ci)場,彈(dan)簧片受壓,當電(dian)壓正弦波(bo)變(bian)化的(de)(de)時候,彈(dan)簧片彈(dan)回來,就產(chan)生了力(li).
