How often should the engine carbon brush be changed?

The frequency of carbon brush replacement is not specified. According to the hardness of the carbon brush itself, the frequency of use and other factors to determine the frequency of replacement. If used frequently, it will be replaced in about a year. The main role of carbon brush is to rub metal while conducting electricity, mostly used in electric motors. Carbon brush commutation performance is good, long service life, suitable for all kinds of motor, generator and axle machine.

The replacement period of the carbon brush of the generator is related to the environment. The specific replacement period is as follows: The environment is good, there is no dust and sand, and the air humidity is not high. The carbon brush can be used for more than 100,000 kilometers. About 50,000 kilometers of dusty rural roads need to be replaced; Carbon brush is an easy to wear object, its wear is difficult to observe. The generator needs to be disassembled to be inspected, so the carbon brush needs to be repaired. Carbon brush can reach 2000h under good commutation conditions, but may only reach 1000h under extreme conditions, and its service life can generally reach 1000H-3000 h.

Carbon brush also known as brush, as a sliding contact, widely used in many electrical equipment. Carbon brush is used in commutator or slip ring of motor, as the sliding contact of drawing and introducing current, it has good electric conductivity, heat conduction and lubrication performance, and has certain mechanical strength and reversible spark instinct. Almost all motors use carbon brush, carbon brush is an important part of the motor. Widely used in all kinds of AC /DC generator, synchronous motor, battery DC motor, crane motor collector ring, all kinds of welders, etc. Carbon brushes are mainly made of carbon and wear easily. Regular maintenance and replacement should be carried out and carbon deposition removed.
