Maintenance opportunities It is recommended that the key components and carbon brushes of the regulator be stopped for inspection and maintenance every three months. 2 Maintenance methods to check whether the carbon brush holder is loose, whether the carbon brush is in the same plane, the same straight line, whether the contact is excellent, showing any kind of situation should be replaced in time, otherwise, it will affect the normal operation and service life of the voltage stabilizer. If it is found that the carbon brush is worn too fast, check whether the coil of the column regulator is smooth and clean, whether there is a flash point; whether the load current is too large.

The spark nature of the spark level determines whether the unit can run 0 normal operation without spark 1 about 1/4 of the carbon brush has no harm to the successive operation of the carbon brush due to a small part of its small cremation points. therefore, it is considered that the practice has no spark reversal, and it is allowed to have 2 carbon brushes folded in half to attack fine sparks. 3 all or most of them have black marks on the slip ring and traces on the carbon brushes, this spark is allowed to exist when the temporary overload starts to change the direction, begging to stop and deal with all 4 carbon brushes to generate considerable sparks, and the operation is not allowed to run.

The carbon brush of the motor and the carbon brush of the generator are also collectively referred to as the motor carbon brush or the motor brush. The commutator is composed of a brush and a commutation ring, and the carbon brush is a kind of brush. Due to the rolling of the rotor, the brush always conflicts with the commutation ring, and the electric spark erosion occurs at the moment of commutation, so the brush is a vulnerable part in the DC motor.

The spark nature of spark grade determines whether the unit can run 0 normal operation without spark 1 about 1/4 of the carbon brush has no harm to the successive operation of the carbon brush due to a small part of its small cremation points. therefore, it is considered that there is no spark reversal in practice, and about half of the carbon brushes are allowed to have fine sparks 3 all or most of them show black marks on the slip ring and traces on the carbon brush during the successive operation, this spark is allowed to exist when it is temporarily overloaded and started to change direction. Please stop and deal with it. 4 All carbon brushes will generate considerable sparks. Work is not allowed. Operation is not allowed.

The effect of motor carbon brushes in the motor:

1. Add the external current (excitation current) to the rolling rotor (input current) through the carbon brush. 2. Introduce the electrostatic charge on the large shaft into the ground (grounding carbon brush) (output current) through the carbon brush. 3. Change the current direction (in commutator motor, the brush also plays a commutation effect). 4. Lead the large shaft (ground) to the protection equipment for rotor grounding protection and measure the positive and negative ground electricity of the rotor.

Natural running-in method equipment process: power failure admission> removal of old carbon brushes> removal of old carbonized film (this operation is required when replacing carbon brushes of different materials or when the carbonized film is too thick)> cleaning the inside of the motor> new carbon brushes of equipment> equipment viewing> natural running-in (about 0.5-3 hours, depending on the size and size)> completion
