壓電振動盤和電磁振動盤的區別

1、電(dian)磁(ci)式振(zhen)動(dong)(dong)(dong)(dong)盤是由(you)(you)一個電(dian)磁(ci)振(zhen)動(dong)(dong)(dong)(dong)器(電(dian)磁(ci)吸鐵和銜鐵的總稱)作動(dong)(dong)(dong)(dong)力，將電(dian)能轉換為(wei)機械振(zhen)動(dong)(dong)(dong)(dong)能，料(liao)斗(dou)(dou)下面有(you)個脈沖電(dian)磁(ci)鐵，可以(yi)使料(liao)斗(dou)(dou)垂直方向振(zhen)動(dong)(dong)(dong)(dong)，由(you)(you)于多組(3組及以(yi)上)彈簧片的傾(qing)斜，使料(liao)斗(dou)(dou)繞其垂直軸做扭擺振(zhen)動(dong)(dong)(dong)(dong)。料(liao)斗(dou)(dou)內零件(jian)，由(you)(you)于受到(dao)這(zhe)種振(zhen)動(dong)(dong)(dong)(dong)，而沿螺旋軌(gui)道上升，直到(dao)送到(dao)出料(liao)口(kou)。

2、壓電(dian)式(shi)振(zhen)(zhen)(zhen)動(dong)(dong)(dong)盤是(shi)利(li)用壓電(dian)陶瓷(ci)作(zuo)為驅(qu)動(dong)(dong)(dong)源的新型(xing)振(zhen)(zhen)(zhen)動(dong)(dong)(dong)送料(liao)裝(zhuang)(zhuang)置，它利(li)用壓電(dian)片的逆壓電(dian)效(xiao)應產生振(zhen)(zhen)(zhen)動(dong)(dong)(dong)，作(zuo)為驅(qu)動(dong)(dong)(dong)源驅(qu)動(dong)(dong)(dong)料(liao)槽(cao)實現(xian)物料(liao)的輸送。它具有許多傳統振(zhen)(zhen)(zhen)動(dong)(dong)(dong)送料(liao)裝(zhuang)(zhuang)置所不具備(bei)的特點:

(1)結構簡單，安裝和(he)維護更加(jia)方便(bian);

(2)應用壓電(dian)(dian)片作為驅(qu)動(dong)源，無需電(dian)(dian)機、電(dian)(dian)磁(ci)激振器等(deng)驅(qu)動(dong)裝置，也(ye)無需軸(zhou)、桿、皮(pi)帶(dai)等(deng)機械傳動(dong)部(bu)件，結構簡單，易于(yu)加工(gong)制作;

(3)改變(bian)驅動(dong)信號中的幅值、脈寬及頻率中的任意(yi)一(yi)個，都可以調節(jie)輸送(song)率，控制參數多(duo)，可控性好; ;

(4)無轉動慣性(xing)(xing)，幾乎沒有(you)加速(su)(su)和減速(su)(su)過程，啟動、停(ting)止(zhi)迅(xun)速(su)(su)，反應(ying)性(xing)(xing)能快;

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

(6)在低頻率(lv)段(duan)或(huo)超(chao)聲(sheng)段(duan)工作，噪音小(xiao);

(7)在(zai)共振或無共振狀態下工作，因此能量(liang)消耗(hao)少(shao);

(8)驅動力略顯不足(zu)，無(wu)法(fa)輸送過(guo)重之料件，因此這類裝(zhuang)置大多應用于物料的微量或精量輸送。
