電磁式振動盤的工作原理：

振動(dong)盤是由振動(dong)板,電(dian)磁(ci)鐵(tie)(tie),銜鐵(tie)(tie),彈簧片,安裝座,減振膠墊組成,利用控(kong)制(zhi)器產(chan)生(sheng)與系(xi)統(tong)固有頻率相(xiang)同(tong)的脈沖(chong)電(dian)流使電(dian)磁(ci)鐵(tie)(tie)勵磁(ci)后,系(xi)統(tong)發生(sheng)共振,銜鐵(tie)(tie)及振動(dong)板會(hui)(hui)快速的拉向(xiang)電(dian)磁(ci)鐵(tie)(tie),因(yin)為下降速度很快,所以(yi)物料(liao)會(hui)(hui)浮(fu)在(zai)空中,并在(zai)重力(li)作用下落向(xiang)料(liao)盤,接著在(zai)彈簧片的作用下,銜鐵(tie)(tie)及振動(dong)板又被推回(hui),這時使料(liao)盤內的物料(liao)向(xiang)前方移動(dong),該作用以(yi)每分鐘(zhong)3000---10000次(ci)或更(geng)高的次(ci)數反復進行,使用權料(liao)盤內的物料(liao)平滑(hua)移動(dong).

交流電(dian)(dian)(dian)(dian)壓(ya)使電(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)鐵產(chan)生磁(ci)(ci)(ci)場,由于頻率很(hen)高,故產(chan)生的(de)(de)磁(ci)(ci)(ci)力(li)(li)也(ye)是瞬間變(bian)(bian)化(hua)的(de)(de),底(di)盤下面有3---6組(zu)一(yi)定(ding)的(de)(de)角度彈(dan)(dan)簧(huang)片(pian),當電(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)鐵同交流電(dian)(dian)(dian)(dian)瞬間產(chan)生磁(ci)(ci)(ci)場,彈(dan)(dan)簧(huang)片(pian)受壓(ya),當電(dian)(dian)(dian)(dian)壓(ya)正弦波變(bian)(bian)化(hua)的(de)(de)時候,彈(dan)(dan)簧(huang)片(pian)彈(dan)(dan)回來,就產(chan)生了力(li)(li).
