壓電振動盤和電磁振動盤的區別

1、電(dian)(dian)(dian)磁(ci)(ci)式振(zhen)(zhen)動(dong)(dong)(dong)盤是由一個電(dian)(dian)(dian)磁(ci)(ci)振(zhen)(zhen)動(dong)(dong)(dong)器(電(dian)(dian)(dian)磁(ci)(ci)吸(xi)鐵和銜鐵的總稱(cheng))作動(dong)(dong)(dong)力(li)，將電(dian)(dian)(dian)能(neng)轉換為機(ji)械振(zhen)(zhen)動(dong)(dong)(dong)能(neng)，料斗下面有個脈沖電(dian)(dian)(dian)磁(ci)(ci)鐵，可以使(shi)料斗垂直方向振(zhen)(zhen)動(dong)(dong)(dong)，由于(yu)多組(zu)(3組(zu)及以上)彈簧片的傾斜，使(shi)料斗繞其垂直軸(zhou)做扭擺振(zhen)(zhen)動(dong)(dong)(dong)。料斗內零件，由于(yu)受到這種振(zhen)(zhen)動(dong)(dong)(dong)，而沿螺旋軌道上升，直到送到出料口。

2、壓(ya)電(dian)式振(zhen)動盤是利用(yong)壓(ya)電(dian)陶(tao)瓷(ci)作為(wei)驅動源(yuan)(yuan)的新型振(zhen)動送(song)(song)料裝(zhuang)置，它(ta)利用(yong)壓(ya)電(dian)片的逆壓(ya)電(dian)效應產生振(zhen)動，作為(wei)驅動源(yuan)(yuan)驅動料槽實(shi)現(xian)物料的輸(shu)送(song)(song)。它(ta)具有許多傳統振(zhen)動送(song)(song)料裝(zhuang)置所(suo)不具備的特點:

(1)結(jie)構(gou)簡單，安裝和維(wei)護更加方便;

(2)應(ying)用壓(ya)電(dian)片作為驅動(dong)源，無(wu)需電(dian)機(ji)、電(dian)磁激振器等(deng)驅動(dong)裝置，也無(wu)需軸、桿、皮(pi)帶等(deng)機(ji)械傳動(dong)部件，結構簡單，易于加工制作;

(3)改(gai)變(bian)驅動信號(hao)中的(de)幅值、脈寬及(ji)頻率中的(de)任意一(yi)個，都可(ke)(ke)以調(diao)節輸(shu)送率，控(kong)制參數多，可(ke)(ke)控(kong)性(xing)好; 

(4)無轉動(dong)慣性，幾(ji)乎沒有加(jia)速(su)(su)和減(jian)速(su)(su)過程(cheng)，啟動(dong)、停止迅速(su)(su)，反應性能(neng)快;

(5)不(bu)產生干(gan)(gan)擾電磁場，也(ye)不(bu)受(shou)電磁干(gan)(gan)擾信號的(de)影(ying)響;

(6)在(zai)低(di)頻(pin)率段或超(chao)聲段工作，噪(zao)音小;

(7)在共(gong)振(zhen)或無(wu)共(gong)振(zhen)狀態下工作，因此能量消耗(hao)少;

(8)驅動力略顯不足，無法(fa)輸(shu)(shu)送(song)過(guo)重之料(liao)件，因此(ci)這類裝置大多應用于物料(liao)的(de)微量或精(jing)量輸(shu)(shu)送(song)。
