WJ-90ⅡA型微电脑风机叶片动态盘测仪是由河北方岛测控技术研究所与北京科技大学、北京矿务局联合开发的具有高品质数字化处理系统功能的专利产品,可对高速机械目标进行微动量跟踪扫描,适用于矿井轴流式风机的动态监测。该机主机显示部份分左、中、右三组数值:左侧两位数值分别显示经编号的动叶数码值;右侧三位数值显示该号动叶的抖动幅值;中间四位数分别反映该号动叶的顶间隙值和传感器扫过叶片的轨迹长短值,从而可得知动叶的安装角度。以上数据是通过叶片识别传感器和数据传感器实现
WJ-90 Ⅱ A microcomputer fan blade dynamic disk tester is a patented product with high-quality digital processing system developed by Hebei Fangdao Measurement and Control Technology Research Institute, Beijing University of Science and Technology and Beijing Mining Bureau, which can micro-control high-speed mechanical targets Momentum tracking scan, suitable for the dynamic monitoring of mine axial fans. Machine main engine shows part of the left, middle and right three groups of values: the left two figures show the number of the paddle digital value; the right three-digit value shows the number of jitter leaves the jitter amplitude; the middle four digits Which respectively reflect the top clearance value of the moving leaf and the length of the path swept by the sensor, so that the mounting angle of the moving leaf can be obtained. The above data is realized by the blade identification sensor and the data sensor
