环压测试仪的操作步骤
一、用途:l本機採用高精度感測器感應,測試紙和紙板之環壓強度、豎壓強度、膠合強度及平壓強度同時也可測試出拉力強度並直接顯示測試值。二、原理:l本機為電子顯示環壓/拉力試驗機,使用馬達傳動螺杆而使夾具移動,將裝置好試樣試驗夾具置於上下兩夾具之間,然後施予規定之速度,上夾具向下壓縮試樣時,上夾具上端的荷重元即感受到壓力;而拉力測試是上夾具向上移動,下夾具向下移動,同樣夾具感受到壓力,並將力轉換成電壓訊號輸給顯示器,結果連用LOADCELL力量感應器連接顯示器自動顯示力量值。
三、操作說明:1.機臺必須接220V+5%50HZ的電源,要有良好的接地保護措施。2.打開面板上的電源開關後,面板得電,顯示器會自動打開程序。3.確認機臺的行程保護裝置是否有效,是否合理。4.將測試試樣放置於夾具中間,依試樣的厚度選擇內盤直徑置於試樣座上(內盤上標示適合試樣厚度以mm為單位),小心地把試樣插入試樣座,並確保插到底部如下圖3,按測試鍵和上升或下降鍵開始測試。5.嚴禁上下夾具直接接觸,或以金屬類試件測試。6.在測試過程中,若有異常狀況,可按停止鍵,關掉電源後立即通知維修人員檢測。待故障排除後方可使用。7.打印機接受顯示器信號後,按打印鍵,即可打印當前日期、時間、次數和最大壓力值。(詳細操作見顯示器操作和打印機操作)8.顯示器接受上壓板頂的壓力感應器之信號,顯示當時最大壓力值。按下清零鍵,可清除顯示器上的數字。按下峰值鍵,在測試時可記錄下測試的最大值。
