1）试验机在样板上施加力，试验机一般情况下要在0.1MM/秒-500MM/秒的速度范围内加载运行。 2）对于不同的材料要求的速度也不同，破裂长和疲劳等等动态和循环测试一般要在很长的时间内完成，而且需要在载荷比较低的伺服油压设备上才能完成的。 3）了解了工作原理后，就应该知道怎么操作了，而上面说到的不同材料的试验机又需要不同的速度，这点问题我们需要留意。 塑料拉力机在运行中也存在一些问题，如何预防这些问题的产生很重要。早期的塑料拉力机是有指针和图标记录器的，操作起来比较复杂，时间比较慢，而现在的塑料拉力机是采用数控器和电脑的软件控制，实现了全自动话的功能效果，操作起来方便，简单，速度快。这种全自动式的测试试验机，大大减少了人力，增加了工作效益，提供工厂的整体效益。

1) the test machine exerts force on the sample plate, and the test machine will normally load running in the range of 0.1MM/ seconds -500MM/ seconds. 2) the speed of different material requirements is also different. The dynamic and cyclic tests such as rupture length and fatigue are usually completed in a long time, and they need to be completed on the servo hydraulic equipment with relatively low load. 3) after knowing the working principle, we should know how to operate, and the test machine for different materials mentioned above needs different speed. We need to pay attention to this problem. There are also some problems in the operation of the plastic pulling machine. How to prevent these problems is very important. Plastic tensile machine is a pointer and early icon recorder, the operation is complex, time is relatively slow, and the plastic tensile machine is now using CNC machine and computer control software, realized the function of automatic word effect, convenient operation, simple and fast. This automatic test test machine greatly reduces manpower, increases work efficiency and provides the overall efficiency of the factory.
