電磁式振動盤的工作原理：

振動(dong)(dong)盤(pan)是由振動(dong)(dong)板,電(dian)磁鐵(tie)(tie)(tie),銜鐵(tie)(tie)(tie),彈(dan)簧片(pian),安(an)裝座,減振膠墊組成,利(li)用控(kong)制器產生(sheng)與系統固有頻率相同的脈沖(chong)電(dian)流使(shi)電(dian)磁鐵(tie)(tie)(tie)勵磁后(hou),系統發生(sheng)共振,銜鐵(tie)(tie)(tie)及(ji)振動(dong)(dong)板會快速(su)的拉向(xiang)電(dian)磁鐵(tie)(tie)(tie),因為(wei)下降速(su)度很快,所以(yi)物(wu)料(liao)會浮在(zai)空中,并在(zai)重力作用下落(luo)向(xiang)料(liao)盤(pan),接著在(zai)彈(dan)簧片(pian)的作用下,銜鐵(tie)(tie)(tie)及(ji)振動(dong)(dong)板又被推回,這時(shi)使(shi)料(liao)盤(pan)內(nei)的物(wu)料(liao)向(xiang)前(qian)方(fang)移動(dong)(dong),該作用以(yi)每分(fen)鐘3000---10000次或更高的次數反復進行,使(shi)用權料(liao)盤(pan)內(nei)的物(wu)料(liao)平(ping)滑移動(dong)(dong).

交流(liu)電(dian)(dian)壓(ya)使(shi)電(dian)(dian)磁(ci)鐵產生磁(ci)場(chang),由于(yu)頻率很高,故(gu)產生的(de)(de)磁(ci)力也(ye)是(shi)瞬間(jian)(jian)變(bian)(bian)化的(de)(de),底盤下面有(you)3---6組一定的(de)(de)角度彈(dan)簧(huang)片,當電(dian)(dian)磁(ci)鐵同交流(liu)電(dian)(dian)瞬間(jian)(jian)產生磁(ci)場(chang),彈(dan)簧(huang)片受壓(ya),當電(dian)(dian)壓(ya)正弦波(bo)變(bian)(bian)化的(de)(de)時候,彈(dan)簧(huang)片彈(dan)回來(lai),就產生了力.
