壓電振動盤和電磁振動盤的區別

1、電(dian)(dian)磁(ci)式(shi)振(zhen)動(dong)(dong)(dong)盤是由(you)一個(ge)電(dian)(dian)磁(ci)振(zhen)動(dong)(dong)(dong)器(qi)(電(dian)(dian)磁(ci)吸(xi)鐵和銜(xian)鐵的總(zong)稱)作動(dong)(dong)(dong)力，將電(dian)(dian)能轉(zhuan)換為機械(xie)振(zhen)動(dong)(dong)(dong)能，料(liao)斗下面有(you)個(ge)脈沖電(dian)(dian)磁(ci)鐵，可以(yi)使料(liao)斗垂(chui)直(zhi)方(fang)向(xiang)振(zhen)動(dong)(dong)(dong)，由(you)于多組(3組及(ji)以(yi)上)彈簧片的傾斜，使料(liao)斗繞其垂(chui)直(zhi)軸做扭擺振(zhen)動(dong)(dong)(dong)。料(liao)斗內零件，由(you)于受到這種振(zhen)動(dong)(dong)(dong)，而沿螺(luo)旋(xuan)軌道(dao)上升，直(zhi)到送到出(chu)料(liao)口。

2、壓(ya)(ya)電(dian)(dian)式振(zhen)動(dong)(dong)盤是利(li)用壓(ya)(ya)電(dian)(dian)陶瓷作(zuo)為驅動(dong)(dong)源的(de)新型振(zhen)動(dong)(dong)送(song)料(liao)裝(zhuang)置，它(ta)利(li)用壓(ya)(ya)電(dian)(dian)片(pian)的(de)逆(ni)壓(ya)(ya)電(dian)(dian)效應產生振(zhen)動(dong)(dong)，作(zuo)為驅動(dong)(dong)源驅動(dong)(dong)料(liao)槽(cao)實現(xian)物料(liao)的(de)輸(shu)送(song)。它(ta)具有許多傳(chuan)統振(zhen)動(dong)(dong)送(song)料(liao)裝(zhuang)置所不具備(bei)的(de)特(te)點:

(1)結構簡(jian)單(dan)，安裝和維護更(geng)加方便;

(2)應(ying)用壓電(dian)片作為驅動源，無需電(dian)機(ji)、電(dian)磁(ci)激(ji)振器(qi)等(deng)驅動裝置(zhi)，也無需軸、桿、皮帶等(deng)機(ji)械傳(chuan)動部(bu)件(jian)，結構簡單，易于加(jia)工制作;

(3)改變驅動(dong)信號中(zhong)的幅值、脈(mo)寬及(ji)頻(pin)率中(zhong)的任意一個，都可以調節輸送率，控(kong)制參數多(duo)，可控(kong)性好; 

(4)無轉動慣性(xing)，幾乎沒有加(jia)速和減(jian)速過(guo)程(cheng)，啟動、停止迅速，反(fan)應性(xing)能快;

(5)不(bu)產生干(gan)擾電磁場，也不(bu)受(shou)電磁干(gan)擾信號(hao)的影響;

(6)在(zai)低頻率(lv)段或超聲段工作，噪音小;

(7)在共振(zhen)或無(wu)共振(zhen)狀態(tai)下工作，因(yin)此能量消耗少;

(8)驅動力略顯不足，無法(fa)輸送過(guo)重之料件，因(yin)此(ci)這類(lei)裝(zhuang)置大多應用于(yu)物料的微量或精量輸送。
