壓電振動盤和電磁振動盤的區別

1、電(dian)磁(ci)式(shi)振(zhen)動(dong)(dong)(dong)盤是由(you)一個(ge)電(dian)磁(ci)振(zhen)動(dong)(dong)(dong)器(電(dian)磁(ci)吸鐵(tie)和(he)銜鐵(tie)的總稱)作動(dong)(dong)(dong)力，將電(dian)能轉換為機械振(zhen)動(dong)(dong)(dong)能，料(liao)斗(dou)下面有個(ge)脈沖電(dian)磁(ci)鐵(tie)，可以使料(liao)斗(dou)垂(chui)直方向(xiang)振(zhen)動(dong)(dong)(dong)，由(you)于多組(3組及以上)彈(dan)簧片的傾斜(xie)，使料(liao)斗(dou)繞其(qi)垂(chui)直軸(zhou)做扭擺振(zhen)動(dong)(dong)(dong)。料(liao)斗(dou)內零件(jian)，由(you)于受(shou)到這種振(zhen)動(dong)(dong)(dong)，而(er)沿螺旋軌道上升，直到送到出料(liao)口。

2、壓電(dian)(dian)(dian)式振(zhen)動(dong)(dong)(dong)盤(pan)是利用(yong)(yong)壓電(dian)(dian)(dian)陶瓷作為驅(qu)動(dong)(dong)(dong)源(yuan)(yuan)的(de)新型振(zhen)動(dong)(dong)(dong)送料裝置，它(ta)利用(yong)(yong)壓電(dian)(dian)(dian)片的(de)逆壓電(dian)(dian)(dian)效應產生(sheng)振(zhen)動(dong)(dong)(dong)，作為驅(qu)動(dong)(dong)(dong)源(yuan)(yuan)驅(qu)動(dong)(dong)(dong)料槽實現物料的(de)輸送。它(ta)具(ju)有(you)許多傳統振(zhen)動(dong)(dong)(dong)送料裝置所(suo)不具(ju)備的(de)特點:

(1)結(jie)構簡(jian)單，安裝和維(wei)護更加(jia)方便(bian);

(2)應用壓電(dian)(dian)片(pian)作(zuo)為驅動(dong)(dong)源，無需電(dian)(dian)機、電(dian)(dian)磁激(ji)振器等驅動(dong)(dong)裝置，也無需軸、桿、皮帶等機械傳動(dong)(dong)部件，結(jie)構(gou)簡(jian)單(dan)，易于加(jia)工制作(zuo);

(3)改變驅動信號(hao)中的幅(fu)值、脈(mo)寬及頻率中的任意(yi)一(yi)個，都可(ke)以調節(jie)輸(shu)送率，控制參數多，可(ke)控性(xing)好; 

(4)無(wu)轉(zhuan)動慣性，幾乎沒有(you)加速(su)(su)和(he)減速(su)(su)過程，啟(qi)動、停止迅速(su)(su)，反(fan)應(ying)性能(neng)快(kuai);

(5)不(bu)產生干擾(rao)(rao)電磁場，也不(bu)受電磁干擾(rao)(rao)信號的影響;

(6)在低頻率段(duan)或超(chao)聲段(duan)工作，噪音(yin)小;

(7)在共振(zhen)或無共振(zhen)狀(zhuang)態下工作，因此(ci)能(neng)量消耗少;

(8)驅動力(li)略顯不足，無法輸送過重(zhong)之(zhi)料件，因此這類裝置大多應用于物料的微量(liang)(liang)或精量(liang)(liang)輸送。
