帶肋鋼筋螺紋鋼松弛試驗機，專機系列
主(zhu)要用于檢測預應力(li)(li)鋼絲、帶肋鋼筋、PC鋼棒和鋼絞線、螺(luo)紋鋼在常溫下的拉(la)伸應力(li)(li)松弛性能。

根據(ju)(ju)國家標準GB/T5224-2003《預應力(li)(li)混(hun)凝土用鋼(gang)絞線(xian)》、GB/T10120-1996《金屬(shu)應力(li)(li)松(song)(song)(song)弛(chi)試(shi)(shi)驗(yan)(yan)(yan)(yan)(yan)(yan)方法》的(de)(de)相關要(yao)求進(jin)行試(shi)(shi)驗(yan)(yan)(yan)(yan)(yan)(yan)，根據(ju)(ju)設定(ding)的(de)(de)試(shi)(shi)驗(yan)(yan)(yan)(yan)(yan)(yan)參數(shu)(shu)(shu)，自(zi)動完成試(shi)(shi)驗(yan)(yan)(yan)(yan)(yan)(yan)過程的(de)(de)控(kong)制、數(shu)(shu)(shu)據(ju)(ju)采集、顯示和保存（主要(yao)參數(shu)(shu)(shu)：試(shi)(shi)驗(yan)(yan)(yan)(yan)(yan)(yan)力(li)(li)、松(song)(song)(song)弛(chi)力(li)(li)、松(song)(song)(song)弛(chi)率(lv)或對數(shu)(shu)(shu)松(song)(song)(song)弛(chi)率(lv)、溫度），試(shi)(shi)驗(yan)(yan)(yan)(yan)(yan)(yan)完成后可以對數(shu)(shu)(shu)據(ju)(ju)進(jin)行分析(xi)和處理，并打印輸(shu)出用戶要(yao)求的(de)(de)試(shi)(shi)驗(yan)(yan)(yan)(yan)(yan)(yan)曲線(xian)及試(shi)(shi)驗(yan)(yan)(yan)(yan)(yan)(yan)報告，可選擇標準要(yao)求的(de)(de)各種試(shi)(shi)驗(yan)(yan)(yan)(yan)(yan)(yan)曲線(xian)（可繪制剩余試(shi)(shi)驗(yan)(yan)(yan)(yan)(yan)(yan)力(li)(li)或對數(shu)(shu)(shu)剩余力(li)(li)、松(song)(song)(song)弛(chi)力(li)(li)或對數(shu)(shu)(shu)松(song)(song)(song)弛(chi)力(li)(li)、松(song)(song)(song)弛(chi)率(lv)或對數(shu)(shu)(shu)松(song)(song)(song)弛(chi)率(lv)、溫度等跟(gen)時間(jian)或對數(shu)(shu)(shu)時間(jian)的(de)(de)關系曲線(xian)）。

技術參數：

大試驗(yan)力 300KN/600KN

有效測量范圍 2%～FS

示值相對誤(wu)差 ±1%

調速范圍 0.01-50mm/min(30噸(dun)）/0.001-25mm/min（60噸(dun)）

拉(la)伸(shen)大空間 1000-1200mm(30噸(dun)）/1600-2000mm(60噸(dun)）

同軸度 15%以內

性能特點：

1、本(ben)機(ji)采用高強(qiang)度(du)主機(ji)結(jie)構，試驗采用計算(suan)機(ji)控(kong)制(zhi)完成全部試驗過程(cheng)，操作均(jun)由鍵盤(pan)及鼠標來(lai)完成。

2、測量、控制系統采(cai)用計算機(ji)總線設計。即以P4工業控制計算機(ji)為(wei)內(nei)核(he)制造，其(qi)運算速度、控制精度、軟件功能、可靠性均能與計算機(ji)匹配達到(dao)良好效(xiao)果

3、采用(yong)(yong)交(jiao)流測量放(fang)大器(qi)避(bi)免了國內其它試(shi)驗機廠(公司)采用(yong)(yong)直流放(fang)大器(qi)易(yi)產生溫漂即“0”點(dian)漂移問題。

4、試驗(yan)力(li)測量分(fen)辨率可達1/300000。
