電磁式振動盤的工作原理：

振(zhen)動(dong)(dong)盤(pan)是由振(zhen)動(dong)(dong)板(ban),電(dian)磁(ci)鐵,銜(xian)鐵,彈簧片,安裝座,減振(zhen)膠墊(dian)組成,利(li)用控制器產生與系統固有頻(pin)率相同(tong)的(de)脈沖(chong)電(dian)流(liu)使(shi)電(dian)磁(ci)鐵勵磁(ci)后,系統發生共(gong)振(zhen),銜(xian)鐵及振(zhen)動(dong)(dong)板(ban)會快速(su)的(de)拉向(xiang)(xiang)電(dian)磁(ci)鐵,因為下(xia)降速(su)度(du)很(hen)快,所以物(wu)(wu)料(liao)(liao)會浮在空中,并在重力作用下(xia)落向(xiang)(xiang)料(liao)(liao)盤(pan),接著在彈簧片的(de)作用下(xia),銜(xian)鐵及振(zhen)動(dong)(dong)板(ban)又被推(tui)回,這時(shi)使(shi)料(liao)(liao)盤(pan)內的(de)物(wu)(wu)料(liao)(liao)向(xiang)(xiang)前(qian)方移(yi)動(dong)(dong),該作用以每分鐘3000---10000次或更高的(de)次數反復進行,使(shi)用權料(liao)(liao)盤(pan)內的(de)物(wu)(wu)料(liao)(liao)平(ping)滑移(yi)動(dong)(dong).

交流電(dian)壓使電(dian)磁(ci)鐵(tie)產生磁(ci)場(chang),由于(yu)頻率(lv)很高,故產生的磁(ci)力也(ye)是(shi)瞬間(jian)(jian)變化的,底盤下面有3---6組一(yi)定(ding)的角(jiao)度彈(dan)簧(huang)片(pian)(pian),當(dang)電(dian)磁(ci)鐵(tie)同交流電(dian)瞬間(jian)(jian)產生磁(ci)場(chang),彈(dan)簧(huang)片(pian)(pian)受壓,當(dang)電(dian)壓正弦(xian)波(bo)變化的時(shi)候(hou),彈(dan)簧(huang)片(pian)(pian)彈(dan)回來,就產生了力.
