Which component problems will cause the generator set to vibrate?

Vibration faults in generator sets are very common, and Haixing Power has been exposed to them more often. According to daily experience, the causes of vibrations mostly come from the failure of internal components. We need to investigate one by one from the following aspects.

1. The shaft system of the linkage part is misaligned, the center lines do not coincide, and the centering is incorrect. The main cause of this failure is poor alignment and improper installation during the installation process. Another situation is that the center lines of some linkage parts are coincident in the cold state, but after running for a period of time due to the deformation of the rotor fulcrum, foundation, etc., the center lines are destroyed again, resulting in vibration.

2. With dieselGenerator setThe connected gears and couplings are defective. This kind of failure mainly manifests as poor gear meshing, severe gear tooth wear, poor wheel lubrication, skewed and misaligned couplings, incorrect tooth shape and pitch of the gear coupling, excessive clearance or severe wear, all of which will cause vibration.

3. Structural defects and installation problems of the diesel generator set itself. This kind of failure mainly manifests as elliptical journal, bent shaft, too large or too small gap between shaft and bearing bush, insufficient stiffness of bearing seat, foundation plate, certain part of foundation and even the entire installation foundation of diesel generator set. Diesel generator set and foundation The plates are not firmly fixed, the foot bolts are loose, the bearing seat and the base plate are loose, etc. If the gap between the shaft and the bearing bush is too large or too small, it can not only cause vibration but also cause abnormalities in the lubrication and temperature of the bearing bush.

In fact, most vibration problems can be prevented through installation steps. Friends who install equipment by themselves should understand the correct steps in advance, or choose a reliable partner and let professionals perform the installation work to avoid improper installation that may cause hidden dangers to the equipment. .
