1. The extinguisher switch is not turned on and the extinguisher wire is shorted. Lack of engine oil (models with protector).
2. Sensor: Disconnect the oil sensor cable and replace the oil sensor if the gasoline engine can start.
3. Ignition system problems: Disconnect the spark plug and start the engine without loading, and observe the spark. It is normal for the spark to be white and red if there is no spark, replace the spark. plug or igniter. A single-phase generator (also called a single-phase alternator) is an alternating current electrical generator that produces a single, continuous alternating voltage. Single-phase generators can be used to produce electricity in single-phase electrical systems.
How to deal with sparking in generator carbon brushes
1. Check if the broom length is too short and reaches the lifeline, causing damageToo little pressure and the brush cannot make contact with the slide. ring;
p>
2. Check whether the spring pressure finger pressure is appropriate. If it is too small, it will cause brush jump discharge;
3. surface finish of the slip ring. If it is too hairy, it will increase the contact resistance of the brush and cause significant sparking.
4. Check the electrical resistance of the rotor to ensure that the resistance is normal; and there is no short circuit between turns;
5. Check if the oil gap in the bearing is too large, causing the slip ring to become electrified when the rotor rotates. the radial runout on the slip ring surface is too large. The brush bounces and sparks;
6. In addition, if the brush is consistent with the one used previously. The brush has current requirements conductor and speed of friction.
Methods to prevent sparking from generator carbon brushes: Check carbon brushes and slip rings daily
1. The wear length of the carbon brushes should not exceed 2/3. When the wear length of the carbon brush exceeds 2/3 (that is, the top of the carbon brush and the top of the brush holder are on the same plane), it should be replaced.
2. There is no spark from the carbon brush. When the carbon brush just begins to spark, it is necessary to find the cause and eliminate it in time.
3. There is no deviation of the carbon brush from the outside of the slip ring, and there is no crack on the edge of the carbon brush.
4. The carbon brush braid is well connected to the brush holder and the carbon brush, and there is no heat or contact with the brush holder.
5.The carbon brush does not jump, shake or get stuck in the brush holder.
