          持久蠕變?cè)囼?yàn)機(jī)的系列結(jié)構(gòu)

                目前國(guó)內(nèi)生產(chǎn)的電子式蠕變持久試驗(yàn)機(jī)有30、50、100、200KN四種規(guī)格。電子式蠕變持久試驗(yàn)機(jī),主要由主機(jī)、高溫爐及溫控系統(tǒng)、測(cè)控系統(tǒng)、附件、計(jì)算機(jī)系統(tǒng)等部分組成。試驗(yàn)機(jī)可單控或群控。RJ系列機(jī)械式蠕變持久試驗(yàn)機(jī)規(guī)格有30、50、100、200KN四種規(guī)格。
            機(jī)械式蠕變持久試驗(yàn)機(jī)主要由主機(jī)、高溫爐及溫控系統(tǒng)、測(cè)變形系統(tǒng)、計(jì)算機(jī)系統(tǒng)等部分組成,試驗(yàn)機(jī)可單控或群控。
          持久蠕變?cè)囼?yàn)機(jī)的結(jié)構(gòu)和原理按結(jié)構(gòu)和原理分機(jī)械式、電子式兩種,機(jī)械式為傳統(tǒng)的產(chǎn)品;電子式是近幾年開發(fā)的新產(chǎn)品。由于電子式蠕變持久試驗(yàn)機(jī)與機(jī)械式相比具有*的優(yōu)點(diǎn),市場(chǎng)需求量急增,尤其是蠕變性能試驗(yàn)的場(chǎng)合。電子式蠕變持久試驗(yàn)機(jī)具有如下特點(diǎn):
            a、 不僅進(jìn)行蠕變持久試驗(yàn),還能進(jìn)行應(yīng)力松弛試驗(yàn)及低周蠕變循環(huán)試驗(yàn);
            b、 無(wú)沖擊自動(dòng)施加或卸除試驗(yàn)力; 
            c、 以多步驟方式控制恒試驗(yàn)力、恒變形、勻試驗(yàn)力速率、勻變形速率,其控制功能符合GB/T228標(biāo)準(zhǔn),能夠進(jìn)行金屬材料短時(shí)高溫拉伸或室溫拉伸試驗(yàn)。雖然電子式試驗(yàn)機(jī)具有上述優(yōu)點(diǎn),但電子式試驗(yàn)機(jī)測(cè)力系統(tǒng)的溫度漂移和標(biāo) 
            定值漂移是無(wú)法*消除的。所以電子式試驗(yàn)機(jī)適合于較短時(shí)間(通常3個(gè)月之內(nèi))試驗(yàn),長(zhǎng)時(shí)間試驗(yàn)建議使用機(jī)械式試驗(yàn)機(jī)。
          持久蠕變?cè)囼?yàn)機(jī)主機(jī)
            上橫梁與臺(tái)面用兩根立柱相連,構(gòu)成門式高剛度框架,臺(tái)面中央裝有滾珠絲杠副。伺服電機(jī)的轉(zhuǎn)動(dòng)經(jīng)減速機(jī),帶動(dòng)絲杠旋轉(zhuǎn)。下拉桿上裝有行程開關(guān),用于保護(hù)下夾頭的極限位置;伺服電機(jī)上的光電編碼器用于下夾頭位置檢測(cè)及試驗(yàn)速度的反饋。速度控制采用了進(jìn)口全數(shù)字交流伺服系統(tǒng),通過(guò)高精度反饋構(gòu)成全閉環(huán)控制,不僅調(diào)速范圍寬,且響應(yīng)速度快而定位時(shí)間短。 
            下拉桿與測(cè)力傳感器聯(lián)接、上拉桿與衡量聯(lián)接均用球形支座,而且兩球座間距大轉(zhuǎn)動(dòng)自如,有效地保證夾頭間同軸度。
          高溫爐及控溫系統(tǒng)
            a、高溫爐 
            我公司生產(chǎn)的高溫爐有對(duì)開式和圓筒式兩種結(jié)構(gòu)。對(duì)開式高溫爐配有轉(zhuǎn)動(dòng)式支架,裝卸試樣方便;圓筒式高溫爐配有電動(dòng)升降結(jié)構(gòu),對(duì)中性好,裝卸試樣也方便。 
            高溫爐采用型HREφ1.5mm(或φ5mm)粗爐絲,低電壓100V(或24V)供電。因此,電爐壽命長(zhǎng),絕緣要求低。 
            b、控溫系統(tǒng)
            采用了日本島電溫度控制儀,該控制儀是智能型調(diào)節(jié)儀,性能可靠,操作簡(jiǎn)單,精度高。選用了可控硅移相式過(guò)零控制電路,防止升溫過(guò)沖不超過(guò)3℃,并且溫度波動(dòng)小。
