壓電振動盤和電磁振動盤的區別

1、電(dian)磁式振(zhen)(zhen)動(dong)(dong)盤是由一個電(dian)磁振(zhen)(zhen)動(dong)(dong)器(電(dian)磁吸(xi)鐵和銜鐵的總稱)作動(dong)(dong)力(li)，將電(dian)能轉換為機械振(zhen)(zhen)動(dong)(dong)能，料(liao)斗下面有個脈(mo)沖(chong)電(dian)磁鐵，可以(yi)使料(liao)斗垂(chui)直方向(xiang)振(zhen)(zhen)動(dong)(dong)，由于多組(3組及(ji)以(yi)上(shang))彈簧(huang)片的傾斜，使料(liao)斗繞其垂(chui)直軸做扭擺振(zhen)(zhen)動(dong)(dong)。料(liao)斗內(nei)零件(jian)，由于受(shou)到這種振(zhen)(zhen)動(dong)(dong)，而沿螺旋軌(gui)道上(shang)升，直到送到出料(liao)口。

2、壓(ya)電(dian)式振動(dong)(dong)(dong)(dong)盤是利用(yong)壓(ya)電(dian)陶瓷作為驅(qu)動(dong)(dong)(dong)(dong)源(yuan)的新型振動(dong)(dong)(dong)(dong)送(song)料裝置(zhi)，它利用(yong)壓(ya)電(dian)片(pian)的逆壓(ya)電(dian)效應產生(sheng)振動(dong)(dong)(dong)(dong)，作為驅(qu)動(dong)(dong)(dong)(dong)源(yuan)驅(qu)動(dong)(dong)(dong)(dong)料槽實現物料的輸送(song)。它具有許多傳統(tong)振動(dong)(dong)(dong)(dong)送(song)料裝置(zhi)所不具備的特點:

(1)結構簡單，安裝和維護(hu)更加方(fang)便;

(2)應(ying)用壓電(dian)片作(zuo)為驅動(dong)(dong)源，無需電(dian)機、電(dian)磁激振器等(deng)驅動(dong)(dong)裝置(zhi)，也無需軸、桿(gan)、皮帶等(deng)機械傳動(dong)(dong)部件，結構(gou)簡單(dan)，易于加(jia)工制作(zuo);

(3)改變驅動信(xin)號中的(de)幅值、脈寬及頻率(lv)中的(de)任(ren)意一(yi)個，都可以調(diao)節輸送率(lv)，控制參數(shu)多(duo)，可控性好(hao); 

(4)無轉動(dong)慣性，幾乎沒有加(jia)速(su)和減速(su)過程(cheng)，啟動(dong)、停(ting)止迅速(su)，反(fan)應性能快;

(5)不產生干擾電磁場，也(ye)不受電磁干擾信號的(de)影響;

(6)在低頻率段(duan)或超(chao)聲段(duan)工(gong)作，噪音小(xiao);

(7)在共(gong)振或(huo)無共(gong)振狀態下工作，因(yin)此(ci)能(neng)量消耗少(shao);

(8)驅動(dong)力略顯不足(zu)，無法輸送(song)過重之料件，因(yin)此(ci)這類(lei)裝置大多應用于物料的微量或(huo)精量輸送(song)。
