overspeed testing meaning in Chinese

超速试验

Overspeed test for industrial fan impeller
工业通风机叶轮超速试验
The effect of oil filler test that is improved is correspondence to the overspeed test , so it is no use to do overspeed test repeatedly . it can reduces the deterioration of the rotor ' s longevity , and that , it can reduce the starting time of the units , which can reduce the cost of fuel consumption and steam deterioration . especially to large capacity steam units that use the same style device , it will get large economic effectiveness
对使用同一原理的装置而言，这种新的技术思路具有指导性意义，改进后的注油试验使用起来的效果可以与超速试验相对应，不需要重复做超速试验，可以减少对因超速对转子的寿命的损耗，并且还缩短了试验所需要的时间，相应减少机组的启动耗时，节约燃料成本及汽水损耗，尤其是对使用同类装置的大容量机组而言，能够获得的经济效益将是巨大的。
