另一種安裝方式是在夾具移動桿邊豎直設(shè)置一根光柵尺和兩根可在豎直方向上移動、帶有小夾子的水平標(biāo)距桿（俗稱：大變形）。這種傳感器的安裝方式和上面所說的手動測量的使用原理是一致的，只是將標(biāo)尺改成光柵尺，將手動操作改成由試樣帶動標(biāo)距桿移動，安徽錨具疲勞試驗機。安裝在標(biāo)距上的傳感器適用于金屬或標(biāo)準(zhǔn)厚度橡膠試樣的拉伸試驗，因為拉伸這些試樣時的力值較大，帶動標(biāo)距桿移動的力值與之相比很小，雖然會對試樣有一定影響，但不足以影響整個試驗的成敗。但橡膠拉伸性能檢測中有一些特殊試樣就不能采取接觸式傳感器進行標(biāo)距測量，例如醫(yī)用橡膠手套試樣。橡膠手套的主要成分為天然乳膠，拉伸試驗過程中所用的拉力值比一般的橡膠制品小，同時GB7543－1996《橡膠醫(yī)用手套》中規(guī)定拉伸性能試驗的試樣是直接在橡膠醫(yī)用手套成品上直接裁取的，所以裁取下的試樣厚度很小，大約只有，這樣厚度的乳膠試樣只需要很小的力值就可以將試樣拉伸很長。所以采取接觸式標(biāo)距測量方式對試樣拉伸試驗會產(chǎn)生很大的影響，影響原因如下：其一，安徽錨具疲勞試驗機，接觸試樣的標(biāo)距桿的自重會將試樣向下扯，影響拉力測量；其二，安徽錨具疲勞試驗機，標(biāo)距桿的夾持對被夾持部位的拉伸有一定的影響，使其不能自由拉伸。檢測設(shè)備一般有疲勞試驗機和游標(biāo)卡尺。安徽錨具疲勞試驗機</p><div

<p> 液壓源由油箱，與伺服電機一體的進口內(nèi)嚙合齒輪泵，電磁閥及閥塊，冷卻器，溢流閥，壓力表等組成。液壓源采用無泄漏技術(shù)，在任何工作環(huán)境和工作狀態(tài)下，油液無外泄及滴漏；液壓源采用降噪音技術(shù)，減少了運行噪音； </p> <p> 液壓源動力采用自適應(yīng)型的伺服泵技術(shù)，即根據(jù)試驗需求，設(shè)定頻率和振幅，當(dāng)這兩個參數(shù)給定的時候，控制系統(tǒng)將根據(jù)兩個參數(shù)自動調(diào)整油泵的流量，從而將系統(tǒng)的發(fā)熱量降到比較低，同時，系統(tǒng)的噪音也降到比較低，系統(tǒng)所消耗的電力、水能源都將降到比較低。該技術(shù)已在我公司大流量的疲勞試驗機上應(yīng)用，其效果十分明顯。浙江合金疲勞試驗機疲勞試驗機特點是可以實現(xiàn)高負(fù)荷、高頻率、低消耗，從而縮短試驗時間，降低試驗費用1。</p><div

6.測力活塞與測力油缸間隙大，在打到高噸位時，可以從測力油缸下部看到。正常情況是看不到滴油或高噸位時有間歇滴油，如果成線狀流出，說明測力活塞應(yīng)更換。在觀察漏油時，應(yīng)注意接頭漏油和缸塞漏油的區(qū)別，且不可由于錯看而得出錯誤的判斷。7.送油閥中活塞與活塞套有損傷或彈簧變軟。這樣每次加載所能達到的負(fù)荷基本不變，送油閥噪音大，當(dāng)負(fù)荷不能再上升時，送油閥回油管出油量大。應(yīng)取出并研磨活塞與活塞套，如損傷嚴(yán)重應(yīng)予更換彈簧。8．送油閥穩(wěn)壓彈簧剛度低或節(jié)流針空腔有堵塞。主要表現(xiàn)：每次加載只能達到一定負(fù)荷，當(dāng)負(fù)荷不能再上升時，回油管出油量大。排除方法：更換剛度適宜的穩(wěn)壓彈簧或清洗臟物。9.送油閥阻尼針與阻尼孔間隙過小。主要表現(xiàn)：每次加載只能達到一定負(fù)荷，當(dāng)負(fù)荷不能再上升時，送油閥回油管出油量大。排除方法：取出阻尼針，沿阻尼針軸向用銼刀適當(dāng)銼去一部分。10.帶動油泵的皮帶松動，有打滑現(xiàn)象。加載到某一負(fù)荷后不能再上升，送油閥回油管無油流出，油泵無工作聲。排除方法：松開電動機固定螺絲，調(diào)整好位置，使皮帶拉緊，再將電動機固定螺絲擰緊。若皮帶變形太大，就得更換新的皮帶。11.油泵柱塞銹蝕。主要表現(xiàn)：在加載過程中。</p><p>

這類故障經(jīng)常發(fā)生，而且產(chǎn)生的原因較多。1.用油黏度太低（加載時送油閥回油管一直有油流出）。一般采用中等黏度的礦物油，不含水、酸及其他混合物，常溫下不分解，不變稠，必要時可用黏度計測量。如果用油不當(dāng)，會使閥門和油路堵塞，并可能引起振動或管路泄露。**好應(yīng)按說明書的要求用油。2.油壓系統(tǒng)嚴(yán)重漏油，油路系統(tǒng)漏油一般都出現(xiàn)在緩沖閥、回油閥、送油閥、油泵及管路的連接處，加墊后擰緊螺絲即可。若是密封墊片壞了，就必須拆開此處更換新的。墊片應(yīng)有紫銅或鋁合金制成。3.油箱油量不足。加載到一定負(fù)荷，送油閥回油管有“噗”、“噗”聲響，且出油少、有氣泡。當(dāng)負(fù)荷不能再上升時，回油管無油流出。排除方法：往試驗機油箱內(nèi)加油，直至看到油液面達到視油窗一半即可。4.油泵的集油器未壓緊在泵體上。這樣每次加載都只能達到一定負(fù)荷，且負(fù)荷不能再上升，送油閥回油管無油流出。排除方法：用扳手將油泵后端的固定螺釘擰緊。如仍有問題，再將集油器卸下，在集油器與泵體之間增加墊圈。5.工作活塞和油缸的配合間隙過大，間隙溢油過多，可以從溢油等出口看到。其辦法是加厚油液的黏度，如果還不能解決問題，經(jīng)過精密測量后，應(yīng)到生產(chǎn)廠調(diào)換活塞和油缸。安徽錨具疲勞試驗機</p><p
