粉體真(zhen)空稱重(zhong)系統由投料(liao)(liao)(liao)(liao)站(zhan)或(huo)物料(liao)(liao)(liao)(liao)儲倉、真(zhen)空加料(liao)(liao)(liao)(liao)機稱重(zhong)裝(zhuang)置、PLC控制器等部件組成(cheng)，可完成(cheng)單物料(liao)(liao)(liao)(liao)定重(zhong)量加料(liao)(liao)(liao)(liao)或(huo)多(duo)種物料(liao)(liao)(liao)(liao)不同配(pei)方配(pei)料(liao)(liao)(liao)(liao)的自動(dong)供料(liao)(liao)(liao)(liao)配(pei)料(liao)(liao)(liao)(liao)。廣(guang)泛(fan)應用(yong)于醫(yi)藥、食(shi)品、化工(gong)、電池材(cai)(cai)料(liao)(liao)(liao)(liao)、建材(cai)(cai)、冶金、飼料(liao)(liao)(liao)(liao)加工(gong)等行(xing)業。

以粉(fen)體(ti)真空稱(cheng)(cheng)(cheng)重(zhong)(zhong)系(xi)(xi)(xi)統應用于兩(liang)種物(wu)(wu)(wu)(wu)料(liao)(liao)自動(dong)稱(cheng)(cheng)(cheng)重(zhong)(zhong)配料(liao)(liao)為例說(shuo)明粉(fen)體(ti)真空承重(zhong)(zhong)系(xi)(xi)(xi)統的工作原理。物(wu)(wu)(wu)(wu)料(liao)(liao)A、B分(fen)別儲存在(zai)兩(liang)個料(liao)(liao)倉中(zhong)(zhong)(zhong)，粉(fen)體(ti)真空稱(cheng)(cheng)(cheng)重(zhong)(zhong)系(xi)(xi)(xi)統開始(shi)工作，真空泵(beng)啟動(dong)，物(wu)(wu)(wu)(wu)料(liao)(liao)A粉(fen)倉底部螺旋(xuan)(xuan)(xuan)放(fang)(fang)料(liao)(liao)閥(fa)A達到(dao)一(yi)定重(zhong)(zhong)量(liang)時(shi)，螺旋(xuan)(xuan)(xuan)停止，放(fang)(fang)料(liao)(liao)閥(fa)A關閉，剩余在(zai)輸送(song)管中(zhong)(zhong)(zhong)的物(wu)(wu)(wu)(wu)料(liao)(liao)繼續被吸(xi)(xi)入到(dao)稱(cheng)(cheng)(cheng)重(zhong)(zhong)料(liao)(liao)斗(dou)中(zhong)(zhong)(zhong)，吸(xi)(xi)凈(jing)后(hou)秤(cheng)中(zhong)(zhong)(zhong)物(wu)(wu)(wu)(wu)料(liao)(liao)A的重(zhong)(zhong)量(liang)正(zheng)好是設定的重(zhong)(zhong)量(liang)。此時(shi)，物(wu)(wu)(wu)(wu)料(liao)(liao)B料(liao)(liao)倉底部螺旋(xuan)(xuan)(xuan)放(fang)(fang)料(liao)(liao)閥(fa)B打開，螺旋(xuan)(xuan)(xuan)啟動(dong)，物(wu)(wu)(wu)(wu)料(liao)(liao)B被吸(xi)(xi)入稱(cheng)(cheng)(cheng)重(zhong)(zhong)料(liao)(liao)斗(dou)中(zhong)(zhong)(zhong)，秤(cheng)中(zhong)(zhong)(zhong)物(wu)(wu)(wu)(wu)料(liao)(liao)B達到(dao)一(yi)定重(zhong)(zhong)量(liang)時(shi)，螺旋(xuan)(xuan)(xuan)停止，放(fang)(fang)料(liao)(liao)閥(fa)B關閉，剩余在(zai)輸送(song)管中(zhong)(zhong)(zhong)的物(wu)(wu)(wu)(wu)料(liao)(liao)繼續被吸(xi)(xi)入到(dao)稱(cheng)(cheng)(cheng)重(zhong)(zhong)料(liao)(liao)斗(dou)中(zhong)(zhong)(zhong)，吸(xi)(xi)凈(jing)后(hou)秤(cheng)中(zhong)(zhong)(zhong)物(wu)(wu)(wu)(wu)料(liao)(liao)B的重(zhong)(zhong)量(liang)正(zheng)好是設定的重(zhong)(zhong)量(liang)。真空泵(beng)停止。

粉(fen)體真(zhen)空稱(cheng)重系統較傳統的粉(fen)體稱(cheng)重系統具有工(gong)藝(yi)流(liu)程短、稱(cheng)重精度高、可(ke)靠性(xing)高、設備(bei)布局高度靈活、大幅降(jiang)低廠房高度等優(you)點。根據稱(cheng)重裝置(zhi)在(zai)粉(fen)體真(zhen)空稱(cheng)重系統中(zhong)不同位置(zhi)，可(ke)組(zu)成多種加法(fa)秤、減法(fa)秤，以適(shi)應客戶的不同要(yao)求。
