壓電振動盤和電磁振動盤的區別

1、電(dian)(dian)磁(ci)(ci)式振(zhen)(zhen)動(dong)(dong)(dong)(dong)(dong)盤(pan)是由(you)(you)一個電(dian)(dian)磁(ci)(ci)振(zhen)(zhen)動(dong)(dong)(dong)(dong)(dong)器(電(dian)(dian)磁(ci)(ci)吸鐵和銜鐵的(de)總稱)作(zuo)動(dong)(dong)(dong)(dong)(dong)力(li)，將電(dian)(dian)能轉換為機(ji)械(xie)振(zhen)(zhen)動(dong)(dong)(dong)(dong)(dong)能，料斗(dou)下面(mian)有(you)個脈沖電(dian)(dian)磁(ci)(ci)鐵，可以使(shi)料斗(dou)垂直(zhi)方向振(zhen)(zhen)動(dong)(dong)(dong)(dong)(dong)，由(you)(you)于多組(3組及以上)彈(dan)簧片的(de)傾斜(xie)，使(shi)料斗(dou)繞其垂直(zhi)軸(zhou)做扭擺振(zhen)(zhen)動(dong)(dong)(dong)(dong)(dong)。料斗(dou)內零件(jian)，由(you)(you)于受(shou)到(dao)(dao)這(zhe)種振(zhen)(zhen)動(dong)(dong)(dong)(dong)(dong)，而沿螺旋(xuan)軌道上升(sheng)，直(zhi)到(dao)(dao)送到(dao)(dao)出料口。

2、壓(ya)(ya)電(dian)式(shi)振動(dong)盤是利(li)用壓(ya)(ya)電(dian)陶瓷(ci)作為(wei)驅(qu)動(dong)源的新型振動(dong)送(song)料裝置(zhi)，它利(li)用壓(ya)(ya)電(dian)片的逆壓(ya)(ya)電(dian)效應產(chan)生振動(dong)，作為(wei)驅(qu)動(dong)源驅(qu)動(dong)料槽實現物料的輸送(song)。它具有許(xu)多傳統振動(dong)送(song)料裝置(zhi)所不具備的特點:

(1)結(jie)構簡單(dan)，安裝和維護更加方(fang)便;

(2)應(ying)用壓電片(pian)作為驅動源，無(wu)(wu)需(xu)電機、電磁激振器等驅動裝置，也(ye)無(wu)(wu)需(xu)軸、桿、皮帶等機械傳動部件，結構簡單，易于加工制作;

(3)改變驅(qu)動信號中(zhong)(zhong)的幅值(zhi)、脈寬及頻率中(zhong)(zhong)的任意一個，都可以調節輸送(song)率，控制參數多(duo)，可控性好(hao); 

(4)無轉動慣性(xing)，幾(ji)乎(hu)沒有加速(su)和減速(su)過程，啟動、停止迅(xun)速(su)，反應性(xing)能快;

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

(6)在低頻率段(duan)或超聲段(duan)工作，噪音小;

(7)在共振(zhen)或無共振(zhen)狀態下工(gong)作(zuo)，因此能(neng)量消耗少;

(8)驅(qu)動力略(lve)顯不(bu)足(zu)，無法輸(shu)送(song)過重之料件(jian)，因此這類裝置大(da)多應用于物料的(de)微量或精量輸(shu)送(song)。
