  液壓萬能試驗機都有哪些部件組成及各部件的作用:

  What are the components of the hydraulic testing machine and their functions?

  液壓試驗機的主要組成部分有主機、檢測、液壓控制、電器、附件以及數據采集處理和控制這些部分。

  The main components of the hydraulic testing machine are the main engine, detection, hydraulic control, electrical appliances, accessories and data acquisition, processing and control.

  1、主機部分:由油缸、底座、立柱、工作活塞、工作臺、試樣夾持、上下移動衡量和活動橫梁等組成,主要的功能是由試樣夾持結構將試樣進行加緊與固定,對試樣進行加載。

  1. Main engine: It is composed of cylinder, base, column, working piston, worktable, sample clamping, up-down movement measurement and moving beam. Its main function is to tighten and fix the sample by sample clamping structure and load the sample.

  2、檢測部分:由電子引伸計、負荷傳感器(壓力傳感器)、光電編碼等,主要功能是對試驗對象所受試驗力、衡量運動的位移以及變形等的檢測。

  2. Detection part: by electronic extensometer, load sensor (pressure sensor), photoelectric coding and so on, the main function is to test the force, displacement and deformation of the test object.

  3、數據采集處理和控制部分:由控制電路、數據的采集和處理、打印機、計算機軟硬件系統、手動控制器件等組成,主要的功能是各種參數的設置、顯示、整個系統的控制、試驗過程與結果的記錄、數據的處理、存儲、試驗結果的輸出等。

  3. Data acquisition, processing and control part: It is composed of control circuit, data acquisition and processing, printer, computer software and hardware system, manual control components, etc. Its main functions are setting, displaying of various parameters, controlling of the whole system, recording of test process and results, data processing, storage and test conclusion. Output of fruit, etc.

  4、附件:由彎曲試驗附件和拉伸、壓縮試驗夾具以及其他一些特殊試驗附件比如說鉗口、夾頭等組成,基本的功能是通過對夾具的更換來完成各種特定的試驗。

  4. Accessories: It consists of bending test accessories, tension, compression test fixtures and other special test accessories such as clamps and chucks. Its basic function is to complete various specific tests by changing fixtures.

  5、液壓控制:主要由高壓油泵、油箱、回油閥、送油閥、截止閥、電液比例閥、工作活塞、測力油缸活塞以及主機的工作油箱等組成,主要的功能是控制試件的加載以及試件的加緊。

  5. Hydraulic control: It is mainly composed of high-pressure oil pump, tank, return valve, delivery valve, globe valve, electro-hydraulic proportional valve, working piston, force measuring cylinder piston and main engine's working tank. Its main function is to control the loading of test pieces and the tightening of test pieces.

  6、電氣部分:由各類繼電器、開關按鈕和交流接觸器等組成,主要功能是控制橫梁升降機構的動作、油泵電機的開關、各種限位和過載保護等。

  6. Electrical part: It is composed of relays, switch buttons and AC contactors. Its main functions are to control the action of lifting mechanism of cross beam, switch of oil pump motor, limit and overload protection. 文章來源:http://m.639cf.cn/
