What Are the Main Mechanical Faults of 350KW Volvo Diesel Generator

Today we are going to introduce to you the main mechanical faults of 350KW Volvo diesel generator.

The shaft system of the linkage part of 350KW Volvo diesel generator is not aligned, the center line is not coincident, and the centering is incorrect. This kind of failure is mainly caused by poor alignment and improper installation during installation. In another case, the center lines of some linkage parts are coincident in cold state, but after a period of operation, the center lines are damaged due to the deformation of rotor fulcrum, foundation, etc., resulting in vibration.

The gear and coupling connected with 350KW Volvo diesel generator are defective. This kind of fault is mainly manifested as poor engagement of gear, serious wear of gear teeth, poor lubrication of the opposite wheel, deflection and dislocation of coupling, incorrect tooth shape and pitch of toothed coupling, excessive clearance or serious wear, which will cause certain vibration.

Structural defects and installation problems of 350KW Volvo diesel generator. This kind of failure is mainly manifested in the ovality of the journal, the bending of the shaft, the excessive or too small clearance between the shaft and the bearing bush, the insufficient rigidity of the bearing pedestal, the foundation plate, some part of the foundation and even the entire Volvo generator set installation foundation, the loose fixation between the Volvo generator set and the foundation plate, the loose foundation bolts, the loose bearing pedestal and the foundation plate, etc. Too large or too small clearance between shaft and bearing bush can not only cause vibration, but also cause abnormal lubrication and temperature of bearing bush.

The load conducted vibration of 350KW Volvo diesel generator. For example, the vibration of the steam turbine of 350KW Volvo diesel generator, the vibration of the fan and water pump driven by 350KW Volvo diesel generator cause the vibration of the Volvo generating set.

Generally, in addition to 350KW Volvo diesel generator, when other brands of units have vibration, you can also use these reasons for reference. So we must face up to the vibration phenomenon during operation. It is likely that there is a problem with an internal component. At this time, it should be repaired in time to eliminate the fault.
