壓電振動盤和電磁振動盤的區別

1、電磁(ci)(ci)式振(zhen)(zhen)動(dong)(dong)(dong)(dong)(dong)盤是(shi)由(you)一個電磁(ci)(ci)振(zhen)(zhen)動(dong)(dong)(dong)(dong)(dong)器(電磁(ci)(ci)吸(xi)鐵(tie)和(he)銜鐵(tie)的(de)總稱)作(zuo)動(dong)(dong)(dong)(dong)(dong)力，將電能轉換為機械振(zhen)(zhen)動(dong)(dong)(dong)(dong)(dong)能，料(liao)(liao)斗(dou)下(xia)面有個脈沖電磁(ci)(ci)鐵(tie)，可(ke)以(yi)使料(liao)(liao)斗(dou)垂(chui)直方(fang)向振(zhen)(zhen)動(dong)(dong)(dong)(dong)(dong)，由(you)于多組(3組及以(yi)上(shang))彈簧片的(de)傾斜，使料(liao)(liao)斗(dou)繞其(qi)垂(chui)直軸做扭(niu)擺振(zhen)(zhen)動(dong)(dong)(dong)(dong)(dong)。料(liao)(liao)斗(dou)內零件，由(you)于受到(dao)這種振(zhen)(zhen)動(dong)(dong)(dong)(dong)(dong)，而沿螺旋軌(gui)道上(shang)升(sheng)，直到(dao)送(song)到(dao)出料(liao)(liao)口。

2、壓電(dian)(dian)式(shi)振(zhen)動(dong)盤(pan)是利用(yong)壓電(dian)(dian)陶瓷作為(wei)驅(qu)(qu)動(dong)源的(de)(de)新型(xing)振(zhen)動(dong)送(song)料(liao)裝置(zhi)，它(ta)利用(yong)壓電(dian)(dian)片的(de)(de)逆壓電(dian)(dian)效應產生(sheng)振(zhen)動(dong)，作為(wei)驅(qu)(qu)動(dong)源驅(qu)(qu)動(dong)料(liao)槽實(shi)現物料(liao)的(de)(de)輸送(song)。它(ta)具有許多傳統振(zhen)動(dong)送(song)料(liao)裝置(zhi)所不具備的(de)(de)特點:

(1)結構(gou)簡單，安(an)裝和維(wei)護更加(jia)方便;

(2)應用壓電(dian)(dian)片作為驅動源(yuan)，無(wu)需(xu)電(dian)(dian)機(ji)、電(dian)(dian)磁激振器(qi)等驅動裝置，也無(wu)需(xu)軸(zhou)、桿、皮帶等機(ji)械傳動部件，結構(gou)簡(jian)單，易于加工制作;

(3)改變驅動信(xin)號中(zhong)的幅值、脈寬及頻率中(zhong)的任意一個(ge)，都可以(yi)調節輸送率，控制(zhi)參數多，可控性好; 

(4)無轉動慣性，幾乎(hu)沒有加速和減(jian)速過程，啟(qi)動、停止迅速，反應性能快(kuai);

(5)不(bu)產生干擾(rao)電磁(ci)場(chang)，也不(bu)受電磁(ci)干擾(rao)信號的(de)影響;

(6)在低頻率段(duan)或超聲段(duan)工(gong)作，噪(zao)音小;

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

(8)驅動力略顯不(bu)足，無法(fa)輸(shu)送(song)過重之料件，因(yin)此(ci)這(zhe)類裝(zhuang)置大(da)多(duo)應(ying)用于(yu)物料的微量(liang)或精量(liang)輸(shu)送(song)。
