壓電振動盤和電磁振動盤的區別

1、電(dian)(dian)磁(ci)式振(zhen)(zhen)(zhen)(zhen)動(dong)(dong)盤是由(you)一個(ge)電(dian)(dian)磁(ci)振(zhen)(zhen)(zhen)(zhen)動(dong)(dong)器(qi)(電(dian)(dian)磁(ci)吸鐵和銜(xian)鐵的總稱)作動(dong)(dong)力，將電(dian)(dian)能轉換為(wei)機(ji)械(xie)振(zhen)(zhen)(zhen)(zhen)動(dong)(dong)能，料(liao)斗(dou)(dou)下面有個(ge)脈(mo)沖電(dian)(dian)磁(ci)鐵，可以使(shi)料(liao)斗(dou)(dou)垂直方(fang)向振(zhen)(zhen)(zhen)(zhen)動(dong)(dong)，由(you)于(yu)多(duo)組(zu)(3組(zu)及以上(shang))彈簧片(pian)的傾(qing)斜，使(shi)料(liao)斗(dou)(dou)繞其(qi)垂直軸做扭擺(bai)振(zhen)(zhen)(zhen)(zhen)動(dong)(dong)。料(liao)斗(dou)(dou)內零件，由(you)于(yu)受到這種振(zhen)(zhen)(zhen)(zhen)動(dong)(dong)，而(er)沿螺(luo)旋軌道(dao)上(shang)升(sheng)，直到送到出料(liao)口(kou)。

2、壓(ya)電式(shi)振(zhen)動(dong)(dong)(dong)盤是利用壓(ya)電陶瓷作為驅動(dong)(dong)(dong)源的(de)新型振(zhen)動(dong)(dong)(dong)送(song)料裝置，它利用壓(ya)電片(pian)的(de)逆壓(ya)電效應產(chan)生(sheng)振(zhen)動(dong)(dong)(dong)，作為驅動(dong)(dong)(dong)源驅動(dong)(dong)(dong)料槽實現物料的(de)輸送(song)。它具有許多傳統振(zhen)動(dong)(dong)(dong)送(song)料裝置所不具備的(de)特點(dian):

(1)結構簡單，安裝(zhuang)和維護(hu)更加方(fang)便;

(2)應用(yong)壓電片作為驅(qu)動(dong)(dong)源，無需電機(ji)、電磁激(ji)振器等驅(qu)動(dong)(dong)裝置，也無需軸、桿、皮帶(dai)等機(ji)械傳動(dong)(dong)部件，結構簡單，易于加(jia)工制作;

(3)改變驅動(dong)信(xin)號中(zhong)的(de)幅(fu)值、脈(mo)寬及(ji)頻率中(zhong)的(de)任意(yi)一個，都(dou)可以調節(jie)輸(shu)送率，控(kong)制參(can)數多，可控(kong)性好(hao); 

(4)無轉動慣性，幾(ji)乎沒(mei)有加速(su)和(he)減速(su)過(guo)程，啟動、停止迅速(su)，反應性能快;

(5)不產生干擾(rao)電磁場(chang)，也不受電磁干擾(rao)信號的影響;

(6)在低頻率段或超聲段工(gong)作(zuo)，噪(zao)音小(xiao);

(7)在(zai)共振或(huo)無共振狀態下工作，因(yin)此能量消(xiao)耗(hao)少(shao);

(8)驅(qu)動力(li)略(lve)顯不足，無法輸(shu)送過重之料(liao)件，因(yin)此這類裝置大(da)多應用于物料(liao)的微量或精量輸(shu)送。
