The main reasons for the wear of
diesel generator carbon brushes include the following:
1. Sliding friction: During normal operation, the contact between the carbon brush and the commutator pole is inevitable, and this continuous sliding friction will cause a certain degree of wear.
2. Poor contact: The roughness of the slip ring surface will affect the contact quality between it and the carbon brush. If the contact is poor, it will cause excessive electric sparks and accelerate the wear of the carbon brush. In addition, if the carbon brush is not replaced in time and the length is too short, resulting in insufficient spring pressure, the carbon brush will also jump on the slip ring, causing poor contact and wear.
3. Uneven spring pressure: Uneven spring pressure on the carbon brush will cause inconsistent pressure on each carbon brush, thereby affecting the wear of the carbon brush.
4. Carbon brush quality: Hard carbon brushes or models that do not meet the requirements will also cause accelerated wear. You should choose carbon brushes of better quality and ensure that the models match.
5. Equipment tilt: The tilt of the equipment will cause problems such as poor contact of the carbon brush and inconsistent spring pressure, affecting the contact surface of the carbon brush, thereby increasing wear.
6. Short circuit phenomenon: Short circuit phenomenon in the circuit is relatively common, and the circuit needs to be checked regularly to prevent the occurrence of short circuit phenomenon.
