壓電振動盤和電磁振動盤的區別

1、電(dian)(dian)磁式振(zhen)(zhen)(zhen)動(dong)(dong)(dong)盤是由一個(ge)電(dian)(dian)磁振(zhen)(zhen)(zhen)動(dong)(dong)(dong)器(qi)(電(dian)(dian)磁吸鐵和銜鐵的總稱(cheng))作動(dong)(dong)(dong)力(li)，將電(dian)(dian)能轉換為機械(xie)振(zhen)(zhen)(zhen)動(dong)(dong)(dong)能，料斗(dou)(dou)下面有個(ge)脈(mo)沖電(dian)(dian)磁鐵，可以使料斗(dou)(dou)垂(chui)直(zhi)方(fang)向(xiang)振(zhen)(zhen)(zhen)動(dong)(dong)(dong)，由于(yu)多組(3組及以上(shang)(shang))彈簧片的傾(qing)斜，使料斗(dou)(dou)繞其(qi)垂(chui)直(zhi)軸(zhou)做扭擺(bai)振(zhen)(zhen)(zhen)動(dong)(dong)(dong)。料斗(dou)(dou)內零件(jian)，由于(yu)受(shou)到這種(zhong)振(zhen)(zhen)(zhen)動(dong)(dong)(dong)，而沿螺旋軌道上(shang)(shang)升，直(zhi)到送到出料口(kou)。

2、壓(ya)電(dian)(dian)式振動(dong)(dong)盤(pan)是利用(yong)壓(ya)電(dian)(dian)陶(tao)瓷作為驅(qu)(qu)動(dong)(dong)源(yuan)的(de)新型振動(dong)(dong)送料(liao)裝(zhuang)置，它(ta)利用(yong)壓(ya)電(dian)(dian)片的(de)逆(ni)壓(ya)電(dian)(dian)效(xiao)應產生(sheng)振動(dong)(dong)，作為驅(qu)(qu)動(dong)(dong)源(yuan)驅(qu)(qu)動(dong)(dong)料(liao)槽實現(xian)物料(liao)的(de)輸送。它(ta)具(ju)有許多傳統振動(dong)(dong)送料(liao)裝(zhuang)置所不具(ju)備的(de)特點:

(1)結構簡單，安(an)裝和維護(hu)更加方便;

(2)應用壓(ya)電(dian)片作(zuo)(zuo)為驅(qu)動源，無(wu)需(xu)(xu)電(dian)機、電(dian)磁激振(zhen)器等驅(qu)動裝置，也無(wu)需(xu)(xu)軸、桿、皮帶等機械傳動部(bu)件，結構簡單(dan)，易于加工制(zhi)作(zuo)(zuo);

(3)改(gai)變驅動信號中(zhong)的幅值、脈(mo)寬及頻率中(zhong)的任意(yi)一個，都可(ke)以調節(jie)輸送率，控制參數多，可(ke)控性好; 

(4)無轉動(dong)慣性，幾(ji)乎沒有(you)加(jia)速(su)和減速(su)過程，啟動(dong)、停止(zhi)迅速(su)，反(fan)應(ying)性能快;

(5)不產生干擾(rao)電(dian)磁場，也不受(shou)電(dian)磁干擾(rao)信(xin)號的影(ying)響;

(6)在低(di)頻率(lv)段或超(chao)聲段工作，噪音小;

(7)在共振或無(wu)共振狀態下工(gong)作(zuo)，因(yin)此能量消耗少;

(8)驅動力略(lve)顯(xian)不(bu)足，無法輸送過重之(zhi)料件，因此這(zhe)類(lei)裝置大(da)多(duo)應用(yong)于物(wu)料的(de)微量(liang)或精量(liang)輸送。
