Embodiment Construction
[0065] Below, the present invention will be described in further detail in conjunction with the accompanying drawings and embodiments.
[0066] Such as figure 1 As shown, in this embodiment, the dynamic balance fault of the rotating machine is detected by the method for detecting the dynamic balance fault of the multi-disc shafting of the rotating machine without a test weight according to the present invention, and the details are as follows:
[0067] Carry out the dynamic balance test after the complete rotating machinery is assembled or under the real state of actual installation on site.
[0068] Such as figure 2 and image 3 As shown, the vibration sensors are arranged in the vertical and horizontal directions of the bearing seats on both sides of the rotor containing multiple discs, a total of 4 vibration sensors. Open the key phase groove (or paste reflective sheet) on the rotating shaft as the 0° mark on the rotating shaft, and define the angle of the reverse rotat...
