Vibration failures of generator sets are very common, and Haixing Power also has a lot of contact. According to daily experience summary, the causes of vibration mostly come from the fault problems of internal components, and everyone needs to check them one by one from the following aspects.
1. The axis system of the linkage part is not centered, the center line does not overlap, and the centering is incorrect. The main reason for this failure is that it is caused by poor alignment and improper installation during the installation process. There is another situation where some linkage center lines overlap and coincide in the cold state, but after running for a period of time, the center lines are destroyed due to deformation of the rotor fulcrum, foundation, etc., which causes vibration.
2. There are problems with the gears and couplings connected to the diesel This type of fault is mainly manifested in poor gear choking, serious wear of the gear teeth, poor lubrication of the gear, skewed and misaligned coupling, tooth shape, wrong tooth pitch, tooth gap, or serious wear, which will cause vibration. generator set .
3. Defects in the structure and installation of the diesel generator set itself. This failure is mainly manifested in the elliptical journal, the bent shaft, the gap between the shaft and the bearing shell is too large or too small, the installation foundation of the bearing seat, foundation plate, a part of the foundation, and even the entire diesel generator set are not stiff enough, the fixing between the diesel generator set and the foundation plate is not firm, the bolts of the foot are loose, and the looseness between the bearing seat and the foundation plate, etc. The gap between the shaft and the bearing shell can not only cause vibration but also cause abnormal lubrication and temperature of the bearing shell.
In fact, we can prevent most vibration problems through installation steps. Friends who install the equipment by themselves should understand the correct steps in advance, or choose reliable partners and leave them to professionals to carry out the installation work, so as not to pose hidden dangers to the equipment if improper installation is posed.
