電磁式振動盤的工作原理：

振動(dong)(dong)盤是由(you)振動(dong)(dong)板,電(dian)(dian)磁鐵(tie),銜(xian)(xian)(xian)鐵(tie),彈簧(huang)片,安裝(zhuang)座,減振膠墊組成(cheng),利(li)用(yong)控制器產生(sheng)與系統(tong)固有頻率(lv)相同(tong)的(de)(de)脈沖電(dian)(dian)流使電(dian)(dian)磁鐵(tie)勵磁后,系統(tong)發生(sheng)共振,銜(xian)(xian)(xian)鐵(tie)及振動(dong)(dong)板會快速(su)的(de)(de)拉向(xiang)電(dian)(dian)磁鐵(tie),因為下降速(su)度很(hen)快,所以物料會浮(fu)在(zai)空中,并在(zai)重力(li)作用(yong)下落向(xiang)料盤,接著在(zai)彈簧(huang)片的(de)(de)作用(yong)下,銜(xian)(xian)(xian)鐵(tie)及振動(dong)(dong)板又被推回(hui),這時使料盤內的(de)(de)物料向(xiang)前方(fang)移動(dong)(dong),該作用(yong)以每(mei)分鐘(zhong)3000---10000次(ci)或更(geng)高(gao)的(de)(de)次(ci)數反(fan)復進(jin)行,使用(yong)權料盤內的(de)(de)物料平滑移動(dong)(dong).

交流電(dian)(dian)壓(ya)使(shi)電(dian)(dian)磁(ci)(ci)鐵產生(sheng)(sheng)磁(ci)(ci)場(chang),由(you)于頻率很高,故產生(sheng)(sheng)的(de)磁(ci)(ci)力也是瞬間變化(hua)的(de),底盤下面有3---6組(zu)一定(ding)的(de)角度彈簧片,當(dang)電(dian)(dian)磁(ci)(ci)鐵同交流電(dian)(dian)瞬間產生(sheng)(sheng)磁(ci)(ci)場(chang),彈簧片受(shou)壓(ya),當(dang)電(dian)(dian)壓(ya)正弦波變化(hua)的(de)時(shi)候,彈簧片彈回來,就(jiu)產生(sheng)(sheng)了力.
