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(shí)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，江蘇疲勞試驗(yàn)機(jī)廠家供應(yīng)，不變稠，必要時(shí)可用黏度計(jì)測(cè)量。如果用油不當(dāng)，會(huì)使閥門和油路堵塞，并可能引起振動(dòng)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(shí)，回油管無(wú)油流出。排除方法：往試驗(yàn)機(jī)油箱內(nèi)加油，直至看到油液面達(dá)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(dá)到一定負(fù)荷，且負(fù)荷不能再上升，送油閥回油管無(wú)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，江蘇疲勞試驗(yàn)機(jī)廠家供應(yīng)，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(cè)量后，應(yīng)到生產(chǎn)廠調(diào)換活塞和油缸。一種主要用于測(cè)定金屬及其合金材料在室溫狀態(tài)下的拉伸，江蘇疲勞試驗(yàn)機(jī)廠家供應(yīng)、壓縮或拉、壓交變負(fù)荷的疲勞性能試驗(yàn)的機(jī)器。江蘇疲勞試驗(yàn)機(jī)廠家供應(yīng)</p><div

7.試樣斷裂時(shí)的伸長(zhǎng)率（扯斷伸長(zhǎng)率）。二、根據(jù)以上所測(cè)參數(shù)的要求。橡膠拉伸試驗(yàn)過程中需要**的數(shù)據(jù)有兩項(xiàng)：拉力力值和標(biāo)距變化量。所以用于測(cè)試橡膠拉伸性能的橡膠拉力試驗(yàn)機(jī)必須滿足以下四個(gè)要求：1.大行程。由于橡膠在拉伸時(shí)變形量很大，尤其是乳膠制品，伸長(zhǎng)率有可能高達(dá)1000%以上。所以在橡膠試樣斷裂之前，必須保證夾持器有足夠的行程。2.高精度及高頻率的數(shù)據(jù)采集。拉伸橡膠不需要很大的力，拉力測(cè)量范圍不需要很大，所以需要力值的精度較高。一般要求測(cè)力儀，拉力機(jī)，硫化儀能夠求取小數(shù)點(diǎn)后兩位以上精度的力值。此外由于檢測(cè)橡膠拉伸性能需要拉伸過程中的數(shù)個(gè)拉力值，而拉伸試驗(yàn)又不可重復(fù)，所以即時(shí)準(zhǔn)確記錄每個(gè)試驗(yàn)段的拉力力值對(duì)于試驗(yàn)成敗起著非常重要的作用。3.準(zhǔn)確的標(biāo)距測(cè)量和記錄裝置（如圖）。試樣標(biāo)距的測(cè)量是計(jì)算橡膠伸長(zhǎng)率的重要數(shù)據(jù)，所以橡膠拉伸試驗(yàn)中拉力試驗(yàn)機(jī)必須準(zhǔn)確地測(cè)量試樣的應(yīng)變量，并即時(shí)地記錄下來。4.可以準(zhǔn)確描述應(yīng)力－應(yīng)變曲線的裝置。拉伸試樣中的拉力值和標(biāo)距之間有著密切的聯(lián)系，例如：試樣的定伸應(yīng)力需要測(cè)量試樣拉伸到給定伸長(zhǎng)率的力值，而定應(yīng)力則需要測(cè)量試樣拉伸到給定應(yīng)力的標(biāo)距。試驗(yàn)完成后。上海超高頻疲勞試驗(yàn)機(jī)疲勞試驗(yàn)機(jī)根據(jù)試驗(yàn)頻率可分為低頻疲勞試驗(yàn)機(jī)、中頻疲勞試驗(yàn)機(jī)、高頻疲勞試驗(yàn)機(jī)、超高頻疲勞試驗(yàn)機(jī)6。</p><div
