電磁式振動盤的工作原理：

振動(dong)(dong)(dong)盤(pan)是由振動(dong)(dong)(dong)板(ban),電(dian)磁鐵(tie),銜鐵(tie),彈簧片,安裝(zhuang)座,減振膠(jiao)墊組成,利用(yong)控制(zhi)器產生與系(xi)統固有(you)頻(pin)率相(xiang)同的(de)(de)(de)(de)脈沖電(dian)流使電(dian)磁鐵(tie)勵磁后,系(xi)統發生共(gong)振,銜鐵(tie)及振動(dong)(dong)(dong)板(ban)會(hui)快速的(de)(de)(de)(de)拉向電(dian)磁鐵(tie),因為下降速度很快,所以(yi)(yi)物(wu)料會(hui)浮在(zai)空中,并(bing)在(zai)重(zhong)力作用(yong)下落向料盤(pan),接(jie)著在(zai)彈簧片的(de)(de)(de)(de)作用(yong)下,銜鐵(tie)及振動(dong)(dong)(dong)板(ban)又被推回,這時(shi)使料盤(pan)內的(de)(de)(de)(de)物(wu)料向前(qian)方移(yi)動(dong)(dong)(dong),該作用(yong)以(yi)(yi)每分鐘3000---10000次或更高的(de)(de)(de)(de)次數(shu)反復(fu)進(jin)行,使用(yong)權料盤(pan)內的(de)(de)(de)(de)物(wu)料平滑移(yi)動(dong)(dong)(dong).

交流電(dian)壓(ya)使電(dian)磁(ci)(ci)鐵(tie)產(chan)(chan)生(sheng)(sheng)磁(ci)(ci)場,由于(yu)頻率很高,故產(chan)(chan)生(sheng)(sheng)的磁(ci)(ci)力也是瞬(shun)間變化(hua)的,底盤下面有3---6組一定(ding)的角度彈(dan)簧片(pian),當電(dian)磁(ci)(ci)鐵(tie)同交流電(dian)瞬(shun)間產(chan)(chan)生(sheng)(sheng)磁(ci)(ci)場,彈(dan)簧片(pian)受壓(ya),當電(dian)壓(ya)正弦波(bo)變化(hua)的時(shi)候(hou),彈(dan)簧片(pian)彈(dan)回來(lai),就產(chan)(chan)生(sheng)(sheng)了力.
