壓電振動盤和電磁振動盤的區別

1、電(dian)(dian)(dian)(dian)磁(ci)式振動(dong)(dong)(dong)盤是由(you)(you)一個(ge)電(dian)(dian)(dian)(dian)磁(ci)振動(dong)(dong)(dong)器(電(dian)(dian)(dian)(dian)磁(ci)吸鐵(tie)和銜鐵(tie)的總稱)作(zuo)動(dong)(dong)(dong)力(li)，將電(dian)(dian)(dian)(dian)能轉(zhuan)換為機械(xie)振動(dong)(dong)(dong)能，料(liao)(liao)(liao)斗(dou)下面有個(ge)脈沖電(dian)(dian)(dian)(dian)磁(ci)鐵(tie)，可以使(shi)料(liao)(liao)(liao)斗(dou)垂(chui)(chui)直方向振動(dong)(dong)(dong)，由(you)(you)于(yu)多組(zu)(3組(zu)及以上(shang))彈簧片的傾斜，使(shi)料(liao)(liao)(liao)斗(dou)繞其垂(chui)(chui)直軸做扭(niu)擺振動(dong)(dong)(dong)。料(liao)(liao)(liao)斗(dou)內零件，由(you)(you)于(yu)受(shou)到(dao)這種振動(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)(liao)口(kou)。

2、壓(ya)(ya)電(dian)式振(zhen)動(dong)盤(pan)是利(li)用(yong)壓(ya)(ya)電(dian)陶瓷作為驅(qu)(qu)動(dong)源的新(xin)型振(zhen)動(dong)送料裝置，它(ta)利(li)用(yong)壓(ya)(ya)電(dian)片的逆壓(ya)(ya)電(dian)效應產(chan)生振(zhen)動(dong)，作為驅(qu)(qu)動(dong)源驅(qu)(qu)動(dong)料槽實現物料的輸送。它(ta)具(ju)有許多傳統振(zhen)動(dong)送料裝置所不具(ju)備(bei)的特點:

(1)結構簡單，安(an)裝和維護更加方便;

(2)應用壓電(dian)片(pian)作為驅動(dong)源，無需電(dian)機(ji)、電(dian)磁激振器等驅動(dong)裝置，也無需軸、桿、皮(pi)帶等機(ji)械(xie)傳動(dong)部(bu)件，結(jie)構簡單，易于加工(gong)制(zhi)作;

(3)改變驅動信號中的幅值、脈寬及頻率中的任意(yi)一個，都可以調節輸送率，控制參數(shu)多(duo)，可控性好(hao); 

(4)無轉(zhuan)動慣(guan)性，幾乎沒有(you)加速和減速過程，啟動、停止迅(xun)速，反應性能快;

(5)不產生干擾電磁(ci)場，也(ye)不受電磁(ci)干擾信(xin)號的(de)影響;

(6)在(zai)低頻率段(duan)或超聲段(duan)工作，噪(zao)音小;

(7)在共(gong)(gong)振(zhen)或(huo)無共(gong)(gong)振(zhen)狀態(tai)下工(gong)作，因(yin)此能量消耗少;

(8)驅動(dong)力(li)略顯不(bu)足，無法(fa)輸送過重(zhong)之料件，因此這類裝置大多(duo)應用于(yu)物料的微量(liang)或精量(liang)輸送。
