*      产品概述:

WAW系列微机控制电液伺服*试验机主要用于金属材料的拉伸、压缩、弯曲等力学性能试验。增加相应附件后可对混凝土、砖、瓦、橡胶及其制品进行检测。

机型B由双立柱双丝杠油缸下置式主机及琴式油源控制柜组成,油泵采用进口低噪音高性能齿轮泵。拉伸空间位于主机上方,压缩、弯曲试验空间位于主机下方即中横梁和工作台之间。试验空间的调整通过中横梁移动来实现,中横梁升降采用链条传动。

机型C采用液压传感器间接测力,横穿移动横梁的蜗轮蜗杆传动机构来调整试验空间,调整试验空间时不需要丝杠旋转,使传动系统与定位系统*分离,保证了上下钳口的同轴度和主机的耐久性。*的丝杠间隙消除机构,保证了试验加载的连续性,电子引申计测试拉伸变形,计算机处理运算数据,具备试验数据屏显和存贮、曲线绘制和分析、打印结果等功能。

本机采用计算机全自动闭环控制、传感器测力、计算机屏幕实时显示、具有存储打印功能、试样液压自动夹紧。试验完成后自动求取材料的zui大力、抗拉强度、屈服强度、弹性模量、断后伸长率、断面收缩率等试验结果。

*      产品特点:

1、特制超厚钳口座在钳口夹持试样时、使钳口*包容在钳口座体内,使试样夹持更加可靠,杜绝了因钳口座浅而呈喇叭状变形损坏的可能,大大提高了设备的使用寿命。

2、在钳口座和钳口卡板之间增加了耐磨衬板,杜绝金属拉伸过程中氧化皮掉入,致使钳口座斜面划伤的现象,使夹持过程更顺滑,加成更牢靠。

3、具有等速应力、等速应变、等速位移、拉伸控制、程序编辑器等多种控制方式,各种控制方式在实验过程中可任意平滑切换。

4、测控软件基于中文windowsXP操作系统平台,具有运行速度快、界面温和、菜单提示、鼠标操作、具有多种试样信息输入模式、可满足不同材料的测试需要。对于相同条件的试样一次输入批量自动生成,还可制作条件模板。

5、试验自动完成后试样信息、试验数据、试验曲线等自动储存。

6、根据试验力大小或材料变形大小自动切换到适当量程,以确保试验数据测量的准确性。

7、试验数据(试验力、位移、变形)加载状态和试验曲线随试验过程动态实时屏幕显示。

8、根据实际需要可选择应力-应变、力-位移、力-时间、位移-时间等曲线上找到试验结果的相关对应点。

9、用户可根据实际需求任意编辑标准文本报表格式或EXCEL文本报表格式

10、当负荷超过满量程的2%-5%时自动过载保护停机

11、可根据试样条件、试验日期和试验数据等条件自动查询所有相关历史记录

12、软件预留数据库接口,方便于实验室间局域联网,便于实验数据管理。
