電磁式振動盤的工作原理：

振動(dong)(dong)盤(pan)是由振動(dong)(dong)板(ban),電磁(ci)(ci)鐵(tie)(tie),銜(xian)鐵(tie)(tie),彈簧片,安裝座,減振膠(jiao)墊(dian)組成,利用(yong)控制器產生(sheng)與系(xi)統固有(you)頻率(lv)相同的脈沖電流使電磁(ci)(ci)鐵(tie)(tie)勵磁(ci)(ci)后,系(xi)統發生(sheng)共振,銜(xian)鐵(tie)(tie)及振動(dong)(dong)板(ban)會快(kuai)速的拉(la)向(xiang)電磁(ci)(ci)鐵(tie)(tie),因為(wei)下降速度很快(kuai),所以(yi)物(wu)(wu)料(liao)會浮在(zai)空中,并在(zai)重力作用(yong)下落向(xiang)料(liao)盤(pan),接著在(zai)彈簧片的作用(yong)下,銜(xian)鐵(tie)(tie)及振動(dong)(dong)板(ban)又被推回,這時使料(liao)盤(pan)內(nei)的物(wu)(wu)料(liao)向(xiang)前方(fang)移(yi)動(dong)(dong),該作用(yong)以(yi)每分鐘3000---10000次(ci)或(huo)更(geng)高的次(ci)數反復進行,使用(yong)權料(liao)盤(pan)內(nei)的物(wu)(wu)料(liao)平滑(hua)移(yi)動(dong)(dong).

交(jiao)(jiao)流(liu)電(dian)(dian)壓使電(dian)(dian)磁鐵產(chan)(chan)(chan)生磁場,由于頻率很高,故產(chan)(chan)(chan)生的磁力也是(shi)瞬間(jian)變(bian)化的,底(di)盤下(xia)面(mian)有(you)3---6組(zu)一定的角(jiao)度(du)彈(dan)簧(huang)(huang)片(pian),當(dang)電(dian)(dian)磁鐵同交(jiao)(jiao)流(liu)電(dian)(dian)瞬間(jian)產(chan)(chan)(chan)生磁場,彈(dan)簧(huang)(huang)片(pian)受壓,當(dang)電(dian)(dian)壓正弦波變(bian)化的時候,彈(dan)簧(huang)(huang)片(pian)彈(dan)回來(lai),就產(chan)(chan)(chan)生了力.
