摘要
液压万能试验机的安装精度对试验机的正常使用至关重要,如果试验机的安装垂直度不能保证,就不能保证轴向拉伸,不仅影响试验的精度,同时也影响油管与油缸、油管与阀门的接口精度,容易造成接口密封问题,造成漏油现象,使试验机的稳压性能降低而导致试验机的工作寿命缩短。
Installation precision of universal testing machine is important to user. If vertical angle of testing machine is not ensured, axis tensile property is not ensured to influence the precision of testing and connect precision between oil pipe and oil cylinder, oil pipe and oil valve. Precision of connector seal easily is decreased to induce oil leakage and decrease stability and working time of testing machine.
