壓電振動盤和電磁振動盤的區別

1、電(dian)磁(ci)(ci)式(shi)振(zhen)(zhen)動(dong)(dong)盤是由一個電(dian)磁(ci)(ci)振(zhen)(zhen)動(dong)(dong)器(電(dian)磁(ci)(ci)吸(xi)鐵和(he)銜鐵的(de)總(zong)稱(cheng))作動(dong)(dong)力，將電(dian)能轉換為機械振(zhen)(zhen)動(dong)(dong)能，料(liao)斗(dou)下面(mian)有個脈(mo)沖(chong)電(dian)磁(ci)(ci)鐵，可(ke)以使(shi)料(liao)斗(dou)垂直方(fang)向振(zhen)(zhen)動(dong)(dong)，由于多組(3組及以上(shang))彈簧片的(de)傾斜，使(shi)料(liao)斗(dou)繞(rao)其垂直軸(zhou)做(zuo)扭(niu)擺振(zhen)(zhen)動(dong)(dong)。料(liao)斗(dou)內(nei)零(ling)件(jian)，由于受到(dao)這(zhe)種振(zhen)(zhen)動(dong)(dong)，而沿螺旋軌道上(shang)升，直到(dao)送到(dao)出料(liao)口(kou)。

2、壓電式振(zhen)動(dong)(dong)(dong)(dong)盤是(shi)利(li)用壓電陶瓷作(zuo)為(wei)(wei)驅動(dong)(dong)(dong)(dong)源(yuan)的新型振(zhen)動(dong)(dong)(dong)(dong)送(song)(song)料(liao)裝(zhuang)置(zhi)，它利(li)用壓電片的逆壓電效應產生振(zhen)動(dong)(dong)(dong)(dong)，作(zuo)為(wei)(wei)驅動(dong)(dong)(dong)(dong)源(yuan)驅動(dong)(dong)(dong)(dong)料(liao)槽實現物料(liao)的輸送(song)(song)。它具有許多傳(chuan)統振(zhen)動(dong)(dong)(dong)(dong)送(song)(song)料(liao)裝(zhuang)置(zhi)所不具備(bei)的特點:

(1)結(jie)構簡單，安(an)裝和維護更(geng)加(jia)方便;

(2)應用(yong)壓電片作(zuo)為驅動源(yuan)，無需電機、電磁(ci)激(ji)振器等驅動裝置，也無需軸、桿、皮帶(dai)等機械傳動部件，結構(gou)簡單，易于加工制作(zuo);

(3)改變驅動信號中的幅值、脈寬(kuan)及頻(pin)率中的任意一個，都可(ke)(ke)以調(diao)節輸送率，控(kong)(kong)制(zhi)參數多，可(ke)(ke)控(kong)(kong)性好(hao); 

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

(5)不產(chan)生(sheng)干擾(rao)電磁場，也不受電磁干擾(rao)信號的影(ying)響;

(6)在低頻率段或(huo)超(chao)聲(sheng)段工作，噪音小;

(7)在共振(zhen)或無共振(zhen)狀(zhuang)態下工作，因此能(neng)量消耗少(shao);

(8)驅動力略顯不(bu)足，無(wu)法(fa)輸(shu)(shu)送過(guo)重之料件，因(yin)此(ci)這類(lei)裝置大(da)多應用(yong)于物料的微(wei)量或(huo)精量輸(shu)(shu)送。
