KCB系列齿轮泵的结构特点：KCB系列齿轮泵主要有齿轮、轴、泵体、安全阀、轴端密封等组成。齿轮泵经热处理有较高的硬度和强度，与轴一同安装在可更换的轴套内运转。泵内全部零件的润滑均在泵工作时利用输送介质而自动达到。泵内有设计合理的泄油和回油槽，使齿轮在工作中承受的扭矩力小，因此轴承负荷小，磨损小，泵效率高。泵设有安全阀作为超载保护，安全阀的全回流压力为泵额定排出压力的1.5倍，也可在允许排出压力范围内根据实际需要另外调整。

后，打开喷枪开始造粒。设备运行后，应及时观察雾化情况及料泵工作状况，若出现堵枪现象需立即清洗或更换喷嘴。设备正常运行后，还应定时收料、定时检查各系统运行情况，记录各工艺参数，并注意清理振动过滤筛。如遇紧急情况，必须立即关停设备，应首先关停送风机和料泵。如果突遇停电，应拉出燃气机，使塔体自然降温，然后打开排污阀，排尽料浆管道内浆料，并清洗设备。造粒是PTC设备长时间运行或因操作不当，部分设备内会出现集料而影响正常运行，此时需停止工作进行清洗。

刀闸阀出现后，大量的通用切断类阀门和调节阀门已被之取代。到今天，全球刀闸阀用量大的是美国和日本。刀型闸阀产品使用中注意事项及其特点:刀型闸阀的启闭件是闸板，闸板的运动方向与流体方向相垂直，刀型闸阀只能作全开和全关,不能作调节和节流。闸板有两个密封面,常用的模式闸板阀的两个密封面形成楔形、楔形角随阀门参数而异,通常为5,楔式刀型闸阀的闸板可以做成一个整体，叫做刚性闸板；也可以做成能产生微量变形的闸板,以改善其工艺性,弥补密封面角度在加工过程中产生的偏差,这种闸板叫做弹性闸板刀型闸阀关闭时,密封面可以只依靠介质压力来密封,即依靠介质压力将闸板的密封面压向另一侧的阀座来保证密封面的密封,这就是自密封.大部分刀型闸阀是采用强制密封的,即阀门关闭时，要依靠外力强行将闸板压向阀座,以保证密封面的密封性。

因为它要求在刚出现屈服现象时改变控制模式，而试验的目的本身就是为了要求取屈服点，怎么可能以未知的结果作为条件进行控制切换呢？所以在现实中，一般都是用同一种控制模式来完成整个的试验的（即使使用不同的控制模式也很难在上屈服点切换，一般会选择超前一点）。对于使用恒位移控制（速度控制）的试验机，由于材料在弹性阶段的应力速率与应变速率成正比关系，只要选择合适的试验速度，全程采用速度控制就可兼容两个阶段的控制特性要求。
