電磁式振動盤的工作原理：

振動(dong)(dong)盤(pan)(pan)是(shi)由振動(dong)(dong)板(ban),電(dian)(dian)磁鐵(tie)(tie),銜(xian)鐵(tie)(tie),彈(dan)簧(huang)片(pian),安裝座,減振膠墊組(zu)成,利用控制器產生與系(xi)統(tong)固有頻率(lv)相同的(de)(de)脈沖電(dian)(dian)流使(shi)電(dian)(dian)磁鐵(tie)(tie)勵磁后,系(xi)統(tong)發生共振,銜(xian)鐵(tie)(tie)及(ji)振動(dong)(dong)板(ban)會快(kuai)速的(de)(de)拉向(xiang)電(dian)(dian)磁鐵(tie)(tie),因為下降(jiang)速度(du)很快(kuai),所以物(wu)料會浮在(zai)空中,并在(zai)重力作用下落(luo)向(xiang)料盤(pan)(pan),接著(zhu)在(zai)彈(dan)簧(huang)片(pian)的(de)(de)作用下,銜(xian)鐵(tie)(tie)及(ji)振動(dong)(dong)板(ban)又被推回,這時使(shi)料盤(pan)(pan)內(nei)的(de)(de)物(wu)料向(xiang)前(qian)方移(yi)動(dong)(dong),該作用以每分鐘3000---10000次或更高(gao)的(de)(de)次數反復進行,使(shi)用權料盤(pan)(pan)內(nei)的(de)(de)物(wu)料平滑移(yi)動(dong)(dong).

交流(liu)電(dian)壓使電(dian)磁(ci)鐵產(chan)生(sheng)磁(ci)場(chang)(chang),由于頻(pin)率很(hen)高,故產(chan)生(sheng)的磁(ci)力也是瞬間變(bian)化的,底盤下面有(you)3---6組一定的角(jiao)度彈(dan)簧片(pian),當電(dian)磁(ci)鐵同交流(liu)電(dian)瞬間產(chan)生(sheng)磁(ci)場(chang)(chang),彈(dan)簧片(pian)受壓,當電(dian)壓正(zheng)弦波變(bian)化的時候(hou),彈(dan)簧片(pian)彈(dan)回來,就產(chan)生(sheng)了力.
