壓電振動盤和電磁振動盤的區別

1、電(dian)(dian)(dian)(dian)磁(ci)式振(zhen)(zhen)動(dong)(dong)(dong)盤是由一個(ge)電(dian)(dian)(dian)(dian)磁(ci)振(zhen)(zhen)動(dong)(dong)(dong)器(電(dian)(dian)(dian)(dian)磁(ci)吸鐵(tie)和銜鐵(tie)的(de)總稱)作動(dong)(dong)(dong)力，將電(dian)(dian)(dian)(dian)能轉換(huan)為機械振(zhen)(zhen)動(dong)(dong)(dong)能，料(liao)斗(dou)下面(mian)有個(ge)脈沖電(dian)(dian)(dian)(dian)磁(ci)鐵(tie)，可以(yi)使料(liao)斗(dou)垂(chui)直方向振(zhen)(zhen)動(dong)(dong)(dong)，由于多組(zu)(3組(zu)及以(yi)上)彈(dan)簧(huang)片的(de)傾斜，使料(liao)斗(dou)繞其垂(chui)直軸做扭(niu)擺振(zhen)(zhen)動(dong)(dong)(dong)。料(liao)斗(dou)內零(ling)件(jian)，由于受(shou)到這種振(zhen)(zhen)動(dong)(dong)(dong)，而沿(yan)螺旋(xuan)軌道(dao)上升，直到送到出料(liao)口。

2、壓(ya)(ya)電式振(zhen)動(dong)(dong)盤是利用壓(ya)(ya)電陶瓷作為驅(qu)動(dong)(dong)源的(de)(de)新型振(zhen)動(dong)(dong)送料(liao)(liao)裝(zhuang)置，它利用壓(ya)(ya)電片的(de)(de)逆壓(ya)(ya)電效(xiao)應產生(sheng)振(zhen)動(dong)(dong)，作為驅(qu)動(dong)(dong)源驅(qu)動(dong)(dong)料(liao)(liao)槽實現物(wu)料(liao)(liao)的(de)(de)輸送。它具有許(xu)多傳統振(zhen)動(dong)(dong)送料(liao)(liao)裝(zhuang)置所不(bu)具備的(de)(de)特點:

(1)結構(gou)簡單，安裝和(he)維(wei)護更加(jia)方便;

(2)應用壓電(dian)片(pian)作為驅動(dong)源，無(wu)需電(dian)機、電(dian)磁激振(zhen)器等驅動(dong)裝置，也無(wu)需軸、桿、皮帶等機械(xie)傳(chuan)動(dong)部件(jian)，結(jie)構簡單，易于加工制作;

(3)改(gai)變(bian)驅動信號(hao)中(zhong)的幅值、脈寬及頻率(lv)中(zhong)的任(ren)意一個(ge)，都可以調節輸送率(lv)，控制參數多(duo)，可控性好(hao); 

(4)無轉(zhuan)動(dong)慣性(xing)，幾乎沒(mei)有加速和減速過(guo)程，啟動(dong)、停(ting)止迅速，反應性(xing)能快(kuai);

(5)不(bu)產生干擾電磁場(chang)，也不(bu)受(shou)電磁干擾信(xin)號的影(ying)響;

(6)在低頻(pin)率段或超聲段工作，噪音(yin)小;

(7)在共振(zhen)或(huo)無共振(zhen)狀態下(xia)工作，因此能量消耗少(shao);

(8)驅動力略顯不足，無法輸送過重之料件，因此這類裝置大多應(ying)用于物(wu)料的(de)微量或(huo)精量輸送。
