  液压万能试验机都有哪些部件组成及各部件的作用:

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

  液压试验机的主要组成部分有主机、检测、液压控制、电器、附件以及数据采集处理和控制这些部分。

  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、主机部分:由油缸、底座、立柱、工作活塞、工作台、试样夹持、上下移动衡量和活动横梁等组成,主要的功能是由试样夹持结构将试样进行加紧与固定,对试样进行加载。

  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、检测部分:由电子引伸计、负荷传感器(压力传感器)、光电编码等,主要功能是对试验对象所受试验力、衡量运动的位移以及变形等的检测。

  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、数据采集处理和控制部分:由控制电路、数据的采集和处理、打印机、计算机软硬件系统、手动控制器件等组成,主要的功能是各种参数的设置、显示、整个系统的控制、试验过程与结果的记录、数据的处理、存储、试验结果的输出等。

  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:由弯曲试验附件和拉伸、压缩试验夹具以及其他一些特殊试验附件比如说钳口、夹头等组成,基本的功能是通过对夹具的更换来完成各种特定的试验。

  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、液压控制:主要由高压油泵、油箱、回油阀、送油阀、截止阀、电液比例阀、工作活塞、测力油缸活塞以及主机的工作油箱等组成,主要的功能是控制试件的加载以及试件的加紧。

  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、电气部分:由各类继电器、开关按钮和交流接触器等组成,主要功能是控制横梁升降机构的动作、油泵电机的开关、各种限位和过载保护等。

  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. 文章来源:http://www.quanlitest.com/
