What are the causes of mechanical wear of Volvo generator? How to reduce wear and tear?

In the case of long-term use of the generator, it will inevitably make the internal parts wear and tear consumption, there is no doubt that this will reduce the performance effect of the equipment and shorten its service life, so we must take reasonable prevention, in order to avoid its very troublesome accidents, so what are the causes of the generator wear? How to reduce wear and tear? The following details:

The cause of mechanical wear of generator

1. Metal normal fatigue wear, which is the inherent characteristics of the metal itself;

2. Fit relationship problem, parts in the process of processing no matter how high the precision of processing, can never reach 100% of the parts fit, fit part of the force surface is small is one of the root causes of metal fatigue wear;

3. The installation problem is that the installation position of the bearing can not be well controlled or the clearance of the bearing can not be effectively controlled during the installation process, which leads to the bearing being unable to be in an optimal state during the operation process, and then the operating resistance increases, the temperature rises, and more torque is applied to the mating surface, leading to the relative movement of the bearing inner ring and the shaft surface, resulting in the wear of the shaft;

4. Operation and maintenance, including poor lubrication of bearings, high operating temperature caused by blockage of cooling system, loose fastening device, etc.

Methods for reducing mechanical wear on generators

1. The number of brushes to be replaced each time should not be too much. At the same time, only 1 to 2 brushes are allowed to be replaced on each brush holder to prevent additional friction resistance.

2. When replacing a new brush, the generator brush should be ground well on the same model as the collector ring in advance, so that it can contact with the collector ring properly.

3. Brush, brush hold gap should meet the requirements of the product, no provisions, the gap can be 0.1 to 0.2 mm, the shape of the brush should be square, the upper and lower end size error should not be greater than 0.05 mm, otherwise can not be used.

Under normal circumstances, the clearance between the brush grip and the collector ring surface is 2 to 3 mm. When adjusting, a layer of 2 to 3 mm thick rubber pad can be attached to the collector ring surface, the brush grip is pressed to the rubber pad, and then the positioning screw is tightened, and the rubber gasket can be removed.

4. During the operation of the generator, the single-three-phase dual-purpose generator should also strengthen the maintenance and management of the collector ring and brush, establish a full-time maintenance system of the collector ring and brush, and carry out inspection and operation and maintenance of the collector ring and brush in strict accordance with the requirements of the generator operating rules.
