壓電振動盤和電磁振動盤的區別

1、電(dian)(dian)磁(ci)式振(zhen)(zhen)(zhen)動(dong)(dong)盤(pan)是由一(yi)個電(dian)(dian)磁(ci)振(zhen)(zhen)(zhen)動(dong)(dong)器(電(dian)(dian)磁(ci)吸(xi)鐵(tie)(tie)和銜鐵(tie)(tie)的總稱(cheng))作動(dong)(dong)力，將電(dian)(dian)能(neng)轉換為機械(xie)振(zhen)(zhen)(zhen)動(dong)(dong)能(neng)，料(liao)斗下面有個脈沖(chong)電(dian)(dian)磁(ci)鐵(tie)(tie)，可(ke)以(yi)使(shi)料(liao)斗垂直(zhi)(zhi)方(fang)向振(zhen)(zhen)(zhen)動(dong)(dong)，由于多組(3組及以(yi)上(shang))彈簧片的傾斜，使(shi)料(liao)斗繞其垂直(zhi)(zhi)軸(zhou)做扭擺振(zhen)(zhen)(zhen)動(dong)(dong)。料(liao)斗內零件(jian)，由于受到(dao)(dao)(dao)這種振(zhen)(zhen)(zhen)動(dong)(dong)，而(er)沿螺旋(xuan)軌道上(shang)升，直(zhi)(zhi)到(dao)(dao)(dao)送到(dao)(dao)(dao)出料(liao)口。

2、壓(ya)電(dian)式振(zhen)動(dong)(dong)(dong)盤是利(li)用壓(ya)電(dian)陶瓷作為(wei)驅(qu)動(dong)(dong)(dong)源的(de)新型振(zhen)動(dong)(dong)(dong)送(song)(song)料(liao)裝置(zhi)(zhi)，它利(li)用壓(ya)電(dian)片的(de)逆壓(ya)電(dian)效應產生振(zhen)動(dong)(dong)(dong)，作為(wei)驅(qu)動(dong)(dong)(dong)源驅(qu)動(dong)(dong)(dong)料(liao)槽實現(xian)物料(liao)的(de)輸送(song)(song)。它具(ju)(ju)有許多傳統(tong)振(zhen)動(dong)(dong)(dong)送(song)(song)料(liao)裝置(zhi)(zhi)所不具(ju)(ju)備的(de)特點(dian):

(1)結構簡單，安裝(zhuang)和(he)維護更加方便(bian);

(2)應用壓電(dian)(dian)片作(zuo)為驅動源，無需電(dian)(dian)機、電(dian)(dian)磁(ci)激振器等驅動裝置，也無需軸、桿、皮帶等機械傳(chuan)動部件，結構簡(jian)單(dan)，易于(yu)加工制作(zuo);

(3)改變(bian)驅動信號中的(de)幅值、脈寬及(ji)頻率中的(de)任意一(yi)個(ge)，都可以調節輸(shu)送率，控制參(can)數多(duo)，可控性(xing)好(hao); 

(4)無轉動慣性(xing)，幾乎(hu)沒有(you)加速和減速過程，啟動、停止迅速，反應(ying)性(xing)能快;

(5)不產生干(gan)擾(rao)(rao)電磁場，也不受電磁干(gan)擾(rao)(rao)信號的(de)影響;

(6)在(zai)低頻(pin)率段或超聲段工作，噪音(yin)小;

(7)在(zai)共振或無共振狀(zhuang)態下(xia)工作，因此能量消耗(hao)少;

(8)驅動(dong)力略顯(xian)不足，無(wu)法(fa)輸送過重之(zhi)料件，因此這(zhe)類裝(zhuang)置大多應(ying)用于物料的微量或(huo)精(jing)量輸送。
