壓電振動盤和電磁振動盤的區別

1、電磁式(shi)振(zhen)(zhen)(zhen)動(dong)盤是(shi)由(you)(you)一個(ge)電磁振(zhen)(zhen)(zhen)動(dong)器(電磁吸(xi)鐵和銜鐵的總(zong)稱(cheng))作動(dong)力，將電能(neng)轉換為機械(xie)振(zhen)(zhen)(zhen)動(dong)能(neng)，料斗(dou)下(xia)面有個(ge)脈沖電磁鐵，可以使料斗(dou)垂直方向振(zhen)(zhen)(zhen)動(dong)，由(you)(you)于多(duo)組(3組及以上(shang)(shang))彈簧片的傾斜，使料斗(dou)繞其(qi)垂直軸(zhou)做扭擺振(zhen)(zhen)(zhen)動(dong)。料斗(dou)內(nei)零件，由(you)(you)于受到這種振(zhen)(zhen)(zhen)動(dong)，而沿螺旋軌道上(shang)(shang)升，直到送到出料口。

2、壓(ya)(ya)電(dian)式(shi)振動(dong)(dong)(dong)(dong)盤是利用(yong)壓(ya)(ya)電(dian)陶瓷作為驅(qu)動(dong)(dong)(dong)(dong)源的(de)新型振動(dong)(dong)(dong)(dong)送(song)料裝置，它利用(yong)壓(ya)(ya)電(dian)片(pian)的(de)逆壓(ya)(ya)電(dian)效應產生振動(dong)(dong)(dong)(dong)，作為驅(qu)動(dong)(dong)(dong)(dong)源驅(qu)動(dong)(dong)(dong)(dong)料槽實(shi)現物料的(de)輸送(song)。它具(ju)有許(xu)多傳統振動(dong)(dong)(dong)(dong)送(song)料裝置所(suo)不具(ju)備(bei)的(de)特(te)點:

(1)結構(gou)簡單，安裝和維護(hu)更加(jia)方便;

(2)應用壓電片(pian)作為(wei)驅動(dong)源，無(wu)需電機、電磁(ci)激(ji)振器等驅動(dong)裝置，也無(wu)需軸、桿、皮(pi)帶等機械傳動(dong)部件，結構(gou)簡單，易于加工(gong)制作;

(3)改變驅(qu)動信號中的幅值、脈寬(kuan)及頻率中的任(ren)意(yi)一個，都可以調節輸送率，控制參數(shu)多，可控性(xing)好; 

(4)無轉動(dong)(dong)慣性(xing)，幾乎(hu)沒有加速(su)和(he)減速(su)過程，啟動(dong)(dong)、停止(zhi)迅速(su)，反應性(xing)能快(kuai);

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

(6)在低頻率(lv)段或超聲段工(gong)作，噪音小;

(7)在共振(zhen)(zhen)或無(wu)共振(zhen)(zhen)狀態下工作，因(yin)此能量消耗少(shao);

(8)驅動力略顯不足，無法輸(shu)送(song)過重(zhong)之(zhi)料件，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)。
