叶片称力矩的目的在于使装配后的叶轮在园周上的不平衡量尽可能地得到最小的数值,其目的也是为转子在作动平衡时,能有一个良好的基础。国外对于叶片称力矩基本上已成为装配中的一道工序,我厂过去也有人提出过,但没有很好进行,以致在叶轮静平衡问题上,一直存在着严重质量事故。经过一段时间的摸索,我们觉得对叶片称力矩(特别是大叶片)是完全必要的,现将所得到的体会和试验效果作一介绍。一、对力矩称的认识力矩称顾名思义是称力矩的(见图①),其方法很简单,即将叶片装在力矩称的左端,利用杠杆原理,在右端装一弹簧,测出每个叶片的力矩数值(以百分表显示读数)由于叶片本身有一制造误差,装在称上
The purpose of the blade moment of force is to minimize the unbalance of the fitted impeller over the circumference of the circle and to provide a good basis for the balancing of the rotor during its operation. Abroad for the blade that torque has basically become a process in the assembly, I plant was also proposed in the past, but not well, so that in the static balance of the impeller, there has been a serious quality accident. After a period of exploration, we feel it is absolutely necessary to call the moment (especially the large blade) on the blade. Now we will introduce the experience and the experience we obtained. First, the moment of understanding known as the name of the moment that the name suggests is the moment (see Figure ①), the method is very simple, the blade is mounted on the left end of the moment said the use of lever principle, the right side of a spring installed to measure each leaf Torque values (readings in percent) Since the blades themselves have a manufacturing error, they are mounted on scales
