電磁式振動盤的工作原理：

振(zhen)(zhen)動(dong)(dong)盤是(shi)由振(zhen)(zhen)動(dong)(dong)板,電(dian)(dian)磁鐵(tie),銜(xian)鐵(tie),彈簧片,安裝座,減振(zhen)(zhen)膠墊組成,利(li)用(yong)控(kong)制器(qi)產生與(yu)系(xi)統固(gu)有頻(pin)率相同的(de)(de)脈沖電(dian)(dian)流使(shi)電(dian)(dian)磁鐵(tie)勵磁后(hou),系(xi)統發(fa)生共振(zhen)(zhen),銜(xian)鐵(tie)及振(zhen)(zhen)動(dong)(dong)板會(hui)快(kuai)(kuai)速的(de)(de)拉向電(dian)(dian)磁鐵(tie),因為下(xia)降速度(du)很快(kuai)(kuai),所以物料會(hui)浮在空中,并在重力(li)作(zuo)(zuo)用(yong)下(xia)落向料盤,接著在彈簧片的(de)(de)作(zuo)(zuo)用(yong)下(xia),銜(xian)鐵(tie)及振(zhen)(zhen)動(dong)(dong)板又被推回,這(zhe)時使(shi)料盤內(nei)(nei)的(de)(de)物料向前方移動(dong)(dong),該(gai)作(zuo)(zuo)用(yong)以每分(fen)鐘3000---10000次或更(geng)高的(de)(de)次數反復進行,使(shi)用(yong)權料盤內(nei)(nei)的(de)(de)物料平滑移動(dong)(dong).

交流電(dian)(dian)(dian)壓使電(dian)(dian)(dian)磁(ci)(ci)鐵(tie)產(chan)(chan)(chan)(chan)生(sheng)(sheng)磁(ci)(ci)場(chang),由于頻率(lv)很高,故產(chan)(chan)(chan)(chan)生(sheng)(sheng)的(de)(de)磁(ci)(ci)力也是瞬間變(bian)化的(de)(de),底盤下(xia)面有(you)3---6組一(yi)定的(de)(de)角度彈(dan)簧(huang)(huang)(huang)片(pian),當電(dian)(dian)(dian)磁(ci)(ci)鐵(tie)同交流電(dian)(dian)(dian)瞬間產(chan)(chan)(chan)(chan)生(sheng)(sheng)磁(ci)(ci)場(chang),彈(dan)簧(huang)(huang)(huang)片(pian)受壓,當電(dian)(dian)(dian)壓正(zheng)弦(xian)波變(bian)化的(de)(de)時(shi)候,彈(dan)簧(huang)(huang)(huang)片(pian)彈(dan)回來,就產(chan)(chan)(chan)(chan)生(sheng)(sheng)了(le)力.
