阻旋式產(chǎn)品及廠家
阻移式料位計(jì)是廣泛應(yīng)用于發(fā)電礦山等行業(yè)對(duì)煤粉、礦粉、水泥、化工原料等粉塵和顆粒料位進(jìn)行控制和監(jiān)測(cè)的儀表。儀表結(jié)構(gòu)簡(jiǎn)單、安裝方便、性能可靠、運(yùn)行周期長(zhǎng)，密封可靠，具有輸出控制信號(hào)和現(xiàn)場(chǎng)顯示雙重功能。無需調(diào)試即可投入運(yùn)行。

阻旋式料位計(jì)是采用微電機(jī)經(jīng)減速后，帶動(dòng)檢測(cè)葉片以5-6轉(zhuǎn)/分的轉(zhuǎn)速旋轉(zhuǎn)的。當(dāng)被測(cè)物料的料位上升使葉片的轉(zhuǎn)動(dòng)受到阻礙時(shí)，檢測(cè)機(jī)構(gòu)便圍繞主軸產(chǎn)生旋轉(zhuǎn)位移。此位移使其中一個(gè)微動(dòng)開關(guān)動(dòng)作發(fā)出有料信號(hào)，隨后另一個(gè)微動(dòng)開關(guān)動(dòng)作，切斷電機(jī)電源使其停轉(zhuǎn)。只要料位不變此種狀態(tài)便將一直保持下去。當(dāng)料位下降檢測(cè)葉片失去阻擋時(shí)，檢測(cè)機(jī)構(gòu)便依靠彈簧拉力恢復(fù)原態(tài)。首先一個(gè)微動(dòng)開關(guān)動(dòng)作接
