遼寧(ning)省沈(shen)陽市30噸每小時種子非連續累計秤的價格

中間計量秤工作原(yuan)理:

物料經由(you)上料斗流(liu)進中(zhong)間計量斗,中(zhong)間計量斗物料裝滿后(hou),上位(wei)料門關(guan)閉,中(zhong)間計量斗進行流(liu)量的稱(cheng)量.稱(cheng)重穩定后(hou),稱(cheng)量的數(shu)值由(you)電(dian)(dian)腦(nao)自動進行累加.電(dian)(dian)腦(nao)累加完之(zhi)后(hou),自動將下(xia)位(wei)料門打開,物料流(liu)入(ru)下(xia)位(wei)放(fang)料斗內(nei).然后(hou)進入(ru)下(xia)一個(ge)循(xun)環(huan).整(zheng)個(ge)過程完全由(you)電(dian)(dian)腦(nao)自動控制(zhi)完成(cheng),無需人工.

在(zai)隨著(zhu)儀表更(geng)新(xin)換(huan)代(dai),特別是(shi)(shi)微電(dian)子技術(shu)引(yin)入稱重儀表制造行(xing)業,所以對于電(dian)子流量秤生產廠家或者是(shi)(shi)使用電(dian)子流量秤的用戶來(lai)說(shuo),儀表精度固(gu)然是(shi)(shi)一(yi)個重要指標,但在(zai)實際使用中(zhong),往往更(geng)強調(diao)儀表的穩定性(xing)(xing)和(he)可靠性(xing)(xing).
