壓電振動盤和電磁振動盤的區別

1、電(dian)(dian)(dian)磁式振動(dong)盤是由(you)一個(ge)電(dian)(dian)(dian)磁振動(dong)器(qi)(電(dian)(dian)(dian)磁吸(xi)鐵和銜(xian)鐵的總(zong)稱(cheng))作動(dong)力，將(jiang)電(dian)(dian)(dian)能轉換(huan)為(wei)機械振動(dong)能，料(liao)斗(dou)(dou)下面有個(ge)脈(mo)沖電(dian)(dian)(dian)磁鐵，可(ke)以使料(liao)斗(dou)(dou)垂直(zhi)方向振動(dong)，由(you)于(yu)多組(zu)(3組(zu)及以上)彈(dan)簧片(pian)的傾斜(xie)，使料(liao)斗(dou)(dou)繞其垂直(zhi)軸做扭擺振動(dong)。料(liao)斗(dou)(dou)內零件，由(you)于(yu)受到(dao)這種振動(dong)，而(er)沿螺旋軌(gui)道上升，直(zhi)到(dao)送到(dao)出料(liao)口。

2、壓電(dian)(dian)(dian)式振(zhen)動(dong)盤是利用(yong)壓電(dian)(dian)(dian)陶(tao)瓷作(zuo)為驅動(dong)源的(de)新型振(zhen)動(dong)送(song)料裝置，它利用(yong)壓電(dian)(dian)(dian)片的(de)逆壓電(dian)(dian)(dian)效(xiao)應產(chan)生振(zhen)動(dong)，作(zuo)為驅動(dong)源驅動(dong)料槽(cao)實現物料的(de)輸送(song)。它具有許(xu)多傳統振(zhen)動(dong)送(song)料裝置所(suo)不具備的(de)特(te)點:

(1)結構簡(jian)單(dan)，安裝和維護更加方便;

(2)應用壓電片作為驅動(dong)(dong)(dong)源，無(wu)(wu)需(xu)電機、電磁激振器等驅動(dong)(dong)(dong)裝置，也無(wu)(wu)需(xu)軸、桿、皮帶(dai)等機械傳動(dong)(dong)(dong)部件，結構簡(jian)單，易于加工(gong)制作;

(3)改變(bian)驅(qu)動信(xin)號中(zhong)的幅值、脈寬及頻(pin)率(lv)中(zhong)的任意一個，都可(ke)以調節輸送率(lv)，控(kong)制參數(shu)多，可(ke)控(kong)性好; 

(4)無轉(zhuan)動(dong)(dong)慣性，幾乎沒(mei)有加速(su)和減(jian)速(su)過程，啟(qi)動(dong)(dong)、停止迅速(su)，反應性能快;

(5)不(bu)產生干(gan)擾電磁場，也不(bu)受電磁干(gan)擾信(xin)號(hao)的影響;

(6)在(zai)低(di)頻率段或超聲段工作(zuo)，噪(zao)音小;

(7)在共(gong)振或無(wu)共(gong)振狀態下工作(zuo)，因此(ci)能(neng)量消耗少(shao);

(8)驅動力(li)略顯不(bu)足(zu)，無法(fa)輸(shu)送過(guo)重之料(liao)件，因此(ci)這類裝置大多(duo)應用(yong)于物料(liao)的微量或精量輸(shu)送。
