  • 瀝青混合料馬歇爾穩定度儀操作說明書

    時間:2013-07-17 作者:admin 點擊:1120次

    瀝青混合料馬歇爾穩定度儀設有過載保護,下降過位保護。操作簡便,測試數據準確,性能穩定可靠。儀器自動試驗,顯示并打印穩定度及對應的流值,繪制試件受力變形的坐標曲線圖

    一、使用范圍
    瀝青混合料馬歇爾穩定度儀以交通部《公路工程及瀝青混合料試驗規程》JTJ052-2000為準,適用于馬歇爾穩定度試驗和浸水馬歇爾穩定度,以進行瀝青混合料的配合比設計或瀝青路面施工質量檢驗。浸水馬歇爾穩定度試驗(根據需要,也可進行真空飽水馬歇爾試驗)供檢驗瀝青混合料受水損害時抵抗剝落的能力時使用,通過測試其水穩定性檢驗配合比設計的可行性。
    二、特點
    ◆采用液晶屏顯示,可動態顯示試驗曲線圖,中文顯示各種試驗數據,直觀方便;
    ◆采用全數字標定壓力和流值,無需手動調整電位器;
    ◆有防錯誤操作和過壓自動保護功能(若過壓,儀器自動停止加壓),不會出現因過壓而損壞儀器。
    三、主要技術參數
    1、壓力    測量范圍:0-30KN;顯示單位:0.01KN(10N)
    2、流值    測量范圍:0-10.00mm(實際可達15.00mm以上)
    3、工作電壓:220V;50HZ
    功    率:電子部分  20W;   機械部分  370W   
    4、打印機:16p微打。
    5、工作溫度:5-35℃;建議在室溫為10-30℃下使用。
    四、操作說明
    1、確認接地良好,插座到位,檢查無誤后即可通電開機。
    2、
    通電后顯示屏顯示如圖一
    3、試驗操作:
    將儀器安裝好,把試件放入壓頭內,插好流值傳感器,按“啟動”鍵,左下方“停止”變為“加載”,試驗開始。儀器自動控制機械部分加載,當加載至試件破碎時,儀器自動停止加載,自動記錄下此試件的大壓力(即穩定度)及其對應的流值,試驗完畢。儀器自動控制機械部分下降至一定高度,方便更換試件。試驗過程中顯示屏實時地顯示試驗狀態,并在試件接觸到傳感器時開始記錄顯示試驗曲線,左下方“停記”變為“記錄”,至試件破碎,并顯示峰值壓力,流量的數據及計算出的模數,如圖二。

    注:如果試件壓力超過3T,儀器過壓,自動保護;同時停止試驗,并將控制部分下降至一定高度。
    4、       打印:配有打印機的用戶在打印機連結無誤,試驗結束后按“打印”按鈕,打印機即打印后一次試驗的曲線及數據。
    5、       手動上升/下降:按住“上升”鍵不放,試件架上升;按住“下降”鍵不放,試件架下降,松開就停止。
    6、       過載保護設定:按“確認”鍵,顯示屏顯示大壓力保護值的設置,一般設30KN。選擇好后,按“確認”鍵,返回到開機狀態。
    7、       力值標定值的設定:
    按“校驗”鍵,提示輸入標定密碼,用“+、-”和“<、>”鍵輸入密碼8888,按“確認”鍵,顯示“壓力標定1設定”,此時是標定值的設定狀態。需要標定的力值點可以分為2點標定或5點標定。

    2點標定設置如下:
    壓力標定1設定  0000KN(此點為0000)按“確認”鍵到下一個點的設定
    壓力標定2設定  0030KN(此點為滿量程)按“確認”鍵到下一個點的設定
    壓力標定3設定  0000KN(不需要的為0)按“確認”鍵到下一個點的設定
    壓力標定4設定  0000KN(不需要的為0)按“確認”鍵到下一個點的設定
    壓力標定5設定  0000KN(不需要的為0)按“確認”鍵到正式標定程序

    5點標定設置如下:
    壓力標定1設定  0000KN(此點為0000)按“確認”鍵到下一個點的設定
    壓力標定2設定  0005KN按“確認”鍵到下一個點的設定
    壓力標定3設定  0010KN按“確認”鍵到下一個點的設定
    壓力標定4設定  0020KN按“確認”鍵到下一個點的設定
    壓力標定5設定  0030KN(此點為滿量程)按“確認”鍵進入正式標定程序
    力值標定程序操作方式:
    力值標定須在有標準測力裝置(如測力環)的情況下進行
    顯示“壓力標定1”             標準:0000KN,
    表示是準備標定*個點,標準力值是0000KN,在傳感器沒受力的情況下,按“確認”鍵,即完成*個點的標定。
    完成*個點標定的同時屏上顯示
    “壓力標定2”,標準:     0005KN,
    表示是準備標定*個點,標準力值是0005KN(此值是由“壓力標定2設定”設置的)手搖手柄加載使受力到0005KN時,按“確認”鍵保存,完成*個點的標定,同時并進入第三個點的標定,依次類推,完成5個點的標定。返回到開機狀態。
    如果只設置了2個標定點,當完成*個點后,儀器完成標定,返回到開機狀態。后面的“壓力標定3”,“壓力標定4”,“壓力標定5”,將不會出現。
    完成力值標定后,儀器的力值測量誤差應保證在精度范圍內,否則重標。
    8、       流值標定值的設定:
    按“校驗”鍵,提示輸入標定密碼,用“+、-”和“<、>”鍵輸入密碼7777,按“確認”鍵,顯示“流值標定1設定”,此時是標定值的設定狀態。需要標定的流值點可以分為2點標定或5點標定。

    2點標值設置如下:
    流值標定1設定  0000mm(此點為起始點)按“確認”鍵到下一個點的設定
    流值標定2設定  0015mm(此點為滿量程)按“確認”鍵到下一個點的設定
    流值標定3設定  0000mm(不需要的為0)按“確認”鍵到下一個點的設定
    流值標定4設定  0000mm(不需要的為0)按“確認”鍵到下一個點的設定
    流值標定5設定  0000mm(不需要的為0)按“確認”鍵到正式標定程序
    4點標定設置如下:
    流值標定1設定  0000mm(此點為起始點)按“確認”鍵到下一個點的設定
    流值標定2設定  0005mm               按“確認”鍵到下一個點的設定
    流值標定3設定  0010mm               按“確認”鍵到下一個點的設定
    流值標定4設定  0015mm(此點為滿量程)按“確認”鍵到下一個點的設定
    流值標定5設定  0000mm(不需要的為0)按“確認”鍵進入正式標定程序

    流值標定程序操作方式:
    顯示“流值標定1”,     標準:0000mm(正式進行標定)
    表示是準備標定*個點,標準流值是0000mm,在流值傳感器為0位時,(位移傳感器滑動桿上兩條刻度線上面一條)按“確認”鍵,即完成*個點的標定。
    同時顯示“流值標定2”,  標準:0005mm,(此值是由“流值標定2設定”設置的)表示是準備標定*個點,標準流值是0005mm,流值傳感器為5mm時,按“確認”鍵,完成*個點的標定,同時并進入第三個點的標定,依次類推,完成4個點的標定。返回到開機狀態(使用標準量塊標定)。
    如果,只設置了2個標定點,(將位移傳感器滑動桿上的兩條刻度線下面一條)按“確認”鍵完成*個點后,儀器完成標定,返回到開機狀態。后面的“流值標定3”,“流值標定4”,“流值標定5”,將不會出現。
    完成流值標定后,儀器的流值測量誤差應保證在精度范圍內,否則重標。

    ★注意事項:

    7、儀器不要與一個大功率用電器共用一電源插座。
    8、儀器應置于干燥處,不要常拔插接件,防止插頭接觸不良。
    9、空氣潮濕的地區,宜將傳感器存放于干燥箱中保存。
    10、儀器不用時,請用布蓋住,防止灰塵侵入。
    11、請不要私自打開或拆卸儀器。
