壓電振動盤和電磁振動盤的區別

1、電(dian)磁(ci)(ci)式振動(dong)(dong)盤是(shi)由一個電(dian)磁(ci)(ci)振動(dong)(dong)器(電(dian)磁(ci)(ci)吸鐵(tie)和(he)銜鐵(tie)的總稱)作動(dong)(dong)力，將電(dian)能轉(zhuan)換為機械(xie)振動(dong)(dong)能，料(liao)(liao)斗下面(mian)有個脈沖電(dian)磁(ci)(ci)鐵(tie)，可以使(shi)料(liao)(liao)斗垂(chui)直(zhi)方向振動(dong)(dong)，由于(yu)多組(zu)(3組(zu)及以上(shang))彈簧(huang)片的傾斜，使(shi)料(liao)(liao)斗繞其垂(chui)直(zhi)軸做扭擺振動(dong)(dong)。料(liao)(liao)斗內(nei)零(ling)件(jian)，由于(yu)受(shou)到這種(zhong)振動(dong)(dong)，而沿螺旋軌道(dao)上(shang)升，直(zhi)到送(song)到出料(liao)(liao)口。

2、壓(ya)電(dian)(dian)式(shi)振(zhen)(zhen)動(dong)(dong)盤是利用壓(ya)電(dian)(dian)陶(tao)瓷作為(wei)驅(qu)(qu)動(dong)(dong)源的(de)新型振(zhen)(zhen)動(dong)(dong)送(song)料裝置，它利用壓(ya)電(dian)(dian)片的(de)逆壓(ya)電(dian)(dian)效應(ying)產生振(zhen)(zhen)動(dong)(dong)，作為(wei)驅(qu)(qu)動(dong)(dong)源驅(qu)(qu)動(dong)(dong)料槽實現物料的(de)輸送(song)。它具(ju)有許多傳統(tong)振(zhen)(zhen)動(dong)(dong)送(song)料裝置所不具(ju)備的(de)特點(dian):

(1)結構簡(jian)單(dan)，安裝(zhuang)和維護更(geng)加方(fang)便;

(2)應用壓電(dian)片作為驅動(dong)源，無需(xu)電(dian)機、電(dian)磁(ci)激(ji)振(zhen)器等(deng)驅動(dong)裝置，也無需(xu)軸、桿、皮(pi)帶(dai)等(deng)機械傳動(dong)部件，結構簡單，易于加工制作;

(3)改(gai)變驅動(dong)信號(hao)中(zhong)(zhong)的幅值、脈(mo)寬及(ji)頻率中(zhong)(zhong)的任意(yi)一個，都可以(yi)調(diao)節輸(shu)送率，控(kong)制參數(shu)多，可控(kong)性好; 

(4)無(wu)轉動慣性，幾(ji)乎(hu)沒有加(jia)速和減速過程，啟(qi)動、停止迅速，反應性能快;

(5)不產(chan)生干擾電磁(ci)場，也不受(shou)電磁(ci)干擾信號的影響(xiang);

(6)在低頻率(lv)段或(huo)超聲段工作，噪(zao)音小(xiao);

(7)在(zai)共振或無共振狀態下(xia)工(gong)作(zuo)，因此(ci)能量消(xiao)耗少;

(8)驅動(dong)力略顯不足，無(wu)法輸送過重之料件(jian)，因此(ci)這類(lei)裝置(zhi)大(da)多應(ying)用于物料的微量或精(jing)量輸送。
