style="text-indent:25px">萬能拉力試驗機安裝有哪些細節(jié)以及對夾具的要求?在裝夾時盡可能的將試樣前后裝平行，平行后再做拉伸；在鋼絲類纏繞夾具中，不能出現(xiàn)線壓線的情況，這樣會造成局部的應力集中，往往會從壓線處斷，造成斷點差；對楔形夾具來說，試樣的左、右對中是由夾具保證的，但前后卻容易裝斜，裝斜后在拉伸過程中試樣兩側(cè)受力不均勻，有可能撕裂試樣或斷點差；對于搭接試樣，應使搭接面通過傳感器的力作用中心。淺析電液伺服萬能試驗機的維護知識？電液伺服萬能試驗機主機采用油缸下置式主機，采用微機控制和顯示功能，主要用于金屬、非金屬的拉伸、壓縮、彎曲和剪切試驗，適用于冶金、建筑、輕工、航空、航天、材料、大專院校、科研單位等領(lǐng)域。任何一款產(chǎn)品在使用過程中都需要使用者合理地維護，才能保證設(shè)備的正常運行。</p><p style="text-indent:25px">電液伺服壓力萬能試驗機是以液壓為主動力的萬能試驗機。主要用于各種固體材料的拉伸，壓縮，彎曲，剪切等強度實驗。與電液試驗機不同的是其實驗時的控制方式必須具備加力速度（或應力速率）、變形速度（或應變速率）及力（或應力）保持和變形（或應變）保持的功能，兩種功能能夠平穩(wěn)切換而不影響實驗結(jié)果。電液伺服萬能試驗機主要有單空間和雙空間兩種結(jié)構(gòu)。單空間試驗機（不論油缸上置型或油缸下置型）只有一個實驗空間，拉伸，壓縮，卷曲等實驗均在此空間進行。傳動器（油缸活塞組）可雙向運動，液壓控制系統(tǒng)較復雜，其特點是拉伸，壓縮，剪切實驗很方便，但是在做彎曲實驗時，由于試驗臺較重，裝卸不太方便。雙空間結(jié)構(gòu)的試驗機，根據(jù)工作油缸在主機的設(shè)置位置，也分為油缸上置型和油缸下置型。雙空間結(jié)構(gòu)試驗機，一般拉伸試驗在一個空間進行。壓縮，彎曲，剪切在另一個空間進行。油缸上置型試驗機，拉伸空間在主機下部空間，實驗時，用升降鉗口座調(diào)整空間，裝夾試樣較方便。電液伺服萬能試驗機清掃與清潔，在試驗過程中不可避免的會產(chǎn)生一些粉塵，如氧化皮、金屬碎屑等等。</p><div

style="text-indent:25px">液壓萬能試驗機的調(diào)試和實驗步驟：油泵在初次運轉(zhuǎn)時候，先將測力計側(cè)面蓋板取下，觀察由送油閥流回油箱的油是否有間歇現(xiàn)象，如果有這種情況可將油泵上面M8堵松開排除空氣再觀察回油箱的油是否斷斷續(xù)續(xù)，如再有此現(xiàn)象可將油泵端面上的外六角螺絲擰下，用鋼絲彎鉤撥動油泵內(nèi)出油閥鋼球，觀察鋼球是否跳動(油泵在開動情況下)待鋼球動后，將六方螺絲擰上，油泵便正常工作。油缸接管后也可能有空氣進入到管內(nèi)，會影響指針轉(zhuǎn)動的不平穩(wěn)，排除的方法就是開動油泵，關(guān)閉回油閥，打開送油閥，使主體工作活塞上升一段距離，然后打開回閥，使油泵經(jīng)工作油缸通過回油閥，回到油箱，這樣循環(huán)一段時間，就能將內(nèi)部空氣排凈，空氣排凈后，再開始作正式試驗。萬能試驗機同步顯示試驗力、峰值、位移、速度、試驗狀態(tài)、試驗曲線等。工程機械液壓試驗臺生產(chǎn)廠家</p><p
